Specification of MMSZ4684 DIODE ZENER 3.3V 500MW SOD123

The MMSZ4684 is a Zener diode. It provides a stable voltage reference. This part is rated for 3.3 volts. Its nominal Zener voltage is 3.3V. You measure this voltage at the test current (Izt) of 20mA. Actual voltage might vary slightly. It falls within a small range around 3.3V. The tolerance is typically ±5%.

This diode comes in a small SOD123 surface mount package. This package is popular for circuit boards. It saves space. The SOD123 has two leads. A visible band marks the cathode end. Correct orientation during assembly is crucial. Check the datasheet for exact dimensions.

Power handling is a key specification. The MMSZ4684 can dissipate up to 500 milliwatts (mW) of power. This is its maximum total power dissipation. Remember this limit. Exceeding it damages the diode. Power dissipation depends on current and voltage. Higher ambient temperatures reduce the safe power level. The diode handles less power when it gets hot. Always consider derating.

The diode operates effectively over a wide temperature range. Standard storage conditions are from -65°C to +175°C. Its performance is stable within these extremes. The Zener voltage changes a little with temperature. This change is its temperature coefficient. The coefficient is usually around -1.9 mV/°C for this voltage. Voltage decreases slightly as temperature increases.

Reverse leakage current is very low before breakdown. It stays minimal below the Zener voltage. This ensures good efficiency. The diode handles moderate currents. Its maximum DC current depends on power and voltage. The dynamic impedance is low. Voltage stays stable even if current changes somewhat.

The MMSZ4684 suits many common applications. It works well for basic voltage regulation tasks. It protects sensitive components from overvoltage spikes. Use it in simple voltage clamping circuits. It fits power supplies needing a stable reference. It is also good for basic signal conditioning. This diode is a reliable choice for 3.3V stabilization needs. Its small size makes it ideal for compact electronics.

Applications of MMSZ4684 DIODE ZENER 3.3V 500MW SOD123

The MMSZ4684 diode is a Zener diode. It controls voltage precisely at 3.3V. This is its key job. It handles up to 500 milliwatts of power. Its small SOD123 package saves space on circuit boards. This makes it good for many electronic uses.

One major use is voltage regulation. Sometimes power supplies aren’t perfectly stable. Their voltage can change. The MMSZ4684 fixes this. When the voltage tries to go above 3.3V, the diode starts conducting heavily. This pulls the voltage back down to 3.3V. It keeps the voltage steady for sensitive parts. This is crucial for microcontrollers or sensors needing exact voltage.

Another important job is protecting circuits. Sudden voltage spikes can damage electronics. These spikes come from power surges or static electricity. Place the MMSZ4684 across the input of a sensitive component. If a spike pushes the voltage over 3.3V, the diode activates. It shorts the excess voltage safely to ground. This stops the high voltage from reaching the protected part. It acts like a pressure relief valve for electricity.

The diode also works well for signal clamping. Signals in circuits sometimes swing too high or too low. This can confuse other components. Use the MMSZ4684 to limit a signal’s maximum voltage. Connect its cathode to the signal line. Connect its anode to ground. If the signal tries to go above 3.3V plus a small diode drop, the diode conducts. This prevents the signal from exceeding that safe level. It clips the top of the waveform cleanly.

You find this diode in many places. It stabilizes voltage for small logic circuits. It protects USB ports or communication lines. It sets reference levels in simple sensor interfaces. Its small size fits into tight spaces like mobile gadgets. Its reliable 3.3V breakdown suits many low-power digital systems perfectly. Its cost is low. Its performance is dependable. It solves common voltage control problems effectively.

5 FAQs of MMSZ4684 DIODE ZENER 3.3V 500MW SOD123

Here are five common questions about the MMSZ4684 3.3V Zener Diode:

What does the MMSZ4684 Zener diode do?
It regulates voltage. It lets current flow forward like a regular diode. But it also lets current flow backwards once a specific voltage is reached. This voltage is 3.3 volts. It protects sensitive parts in your circuit from seeing too much voltage.

How precise is the 3.3V rating?
The actual voltage isn’t exactly 3.3V every time. It has a tolerance. The tolerance is usually ±5%. This means the real voltage could be between 3.135V and 3.465V. Check your specific datasheet for the exact tolerance.

What does the 500mW power rating mean?
This tells you the most power the diode can safely handle. Power is voltage times current. 500mW equals half a watt. You must ensure the diode never gets hotter than this limit. Exceeding it can destroy the diode.

What is the SOD123 package?
SOD123 describes the physical size and shape of the diode. It’s a very small surface-mount package. It looks like a tiny rectangle with two metal ends. This size is common for many diodes. It saves space on circuit boards.

Can I use a different Zener diode instead?
Maybe. But you must check the specifications carefully. The replacement needs the same voltage rating. It needs the same or better power rating. It must also fit the SOD123 footprint. Using a different diode without checking can cause problems.
