Specification of SF36 SF56 SF58 5A/400V/600V direct insertion ultrafast recovery rectifier diode DO-27

Here’s the product information for the SF36, SF56, SF58 diodes. These are direct insertion ultrafast recovery rectifier diodes. They come in the standard DO-27 package. Their main ratings are 5 Amps average forward current, 400 Volts or 600 Volts peak repetitive reverse voltage. The SF36 handles 400V. The SF56 and SF58 handle 600V. They are designed for speed and efficiency.

Ultrafast recovery is their key feature. The reverse recovery time (trr) is very low. It is typically 35 nanoseconds. This fast switching minimizes power loss. It reduces heat generation in circuits. Efficiency improves significantly. This makes them ideal for high-frequency applications. Switching power supplies benefit greatly. Freewheeling diode functions need this speed. Inverter circuits rely on fast diodes. Motor drive controls use these diodes effectively.

The forward voltage drop (VF) is important. At 5A, VF is typically 1.3 Volts. A low VF means less energy wasted as heat. System efficiency gets better. Power dissipation stays manageable. Good thermal performance results. The DO-27 package helps with heat. It provides a solid mounting surface. Heat sinks attach easily. This ensures stable operation.

These diodes handle high surge currents. Non-repetitive surge current (IFSM) is rated at 150 Amps. This offers protection against unexpected spikes. Circuit reliability increases. Transient events are less damaging. The junction temperature range is wide. Operation from -65°C to +150°C is possible. Harsh environments are acceptable. Industrial settings pose no problem. Automotive applications use similar specs.

You will find them in many power conversion tasks. Switch-mode power supplies (SMPS) use them. DC-DC converters need fast diodes. Freewheeling paths in inductive loads require them. Snubber circuits utilize their speed. General-purpose rectification works too. Their robustness suits demanding designs. Engineers trust these diodes for performance. They offer a solid balance of speed, voltage, and current handling.

Applications of SF36 SF56 SF58 5A/400V/600V direct insertion ultrafast recovery rectifier diode DO-27

The SF36, SF56, and SF58 rectifier diodes are essential parts. They are direct insertion components. They fit the DO-27 package standard. These diodes handle 5 amps of current. They are rated for 400 volts or 600 volts. Their key feature is ultrafast recovery. This fast switching matters greatly.

These diodes excel in switch-mode power supplies (SMPS). SMPS need fast switching diodes. Slow diodes cause significant power loss. The ultrafast recovery minimizes this loss. Less power loss means better efficiency. Better efficiency means less heat. Less heat allows smaller heat sinks. This saves space and cost. The SF36/SF56/SF58 are perfect here. They manage high-frequency switching smoothly.

Inverters are another major application. Inverters convert DC power to AC power. They also rely on fast switching. The diodes prevent reverse current flow. Ultrafast recovery is critical for performance. It ensures clean power output. It reduces stress on other components. The 400V/600V ratings suit many inverter designs.

Freewheeling diodes are vital. They protect circuits from voltage spikes. These spikes happen when inductive loads switch off. Think motors or solenoids. The SF36/SF56/SF58 act as freewheeling diodes. Their fast action clamps the spike quickly. This protects sensitive transistors. It prevents damage to the circuit.

The DO-27 package is robust. It allows easy mounting on circuit boards. Its axial leads simplify manual insertion. The diodes offer high surge current capability. This handles unexpected overloads briefly. They provide reliable performance. Their ultrafast characteristic improves overall system speed. It enhances power conversion efficiency. These diodes are workhorses. They are found in power supplies, motor drives, welding equipment. Any application demanding fast, efficient rectification considers them. Their specifications make them a practical choice.

5 FAQs of SF36 SF56 SF58 5A/400V/600V direct insertion ultrafast recovery rectifier diode DO-27

Here are five common questions about the SF36, SF56, and SF58 5A/400V/600V direct insertion ultrafast recovery rectifier diodes in DO-27 packages:

What are these diodes used for? These diodes convert AC power to DC power. They are ultrafast. This makes them perfect for switch-mode power supplies. They work well in high-frequency inverters. They handle high-frequency switching efficiently.

How fast are they really? Their reverse recovery time is extremely short. This is the key ultrafast feature. It minimizes switching losses. This means less wasted energy. It also reduces heat generation in circuits. Performance improves significantly at high frequencies.

What do the voltage ratings mean? The 5A rating is the average forward current. Voltages? Both matter. 400V is the repetitive peak reverse voltage. 600V is the non-repetitive peak reverse voltage. These ratings show the maximum reverse voltage the diode can block safely.

What is the DO-27 package? DO-27 is a common axial-leaded package. It has a cylindrical body. The leads come straight out from each end. This design suits direct insertion into circuit boards. It allows easy mounting. Soldering is straightforward. The package is reliable for power applications.

Why choose ultrafast recovery? Standard rectifiers are too slow for modern power electronics. They cause excessive losses at high speed. Ultrafast diodes like these solve that problem. They switch off very quickly. This prevents current from flowing backwards inefficiently. System efficiency gets better. Heat sinks can potentially be smaller.
