Specification of MMSZ5238B DIODE ZENER 8.7V 500MW SOD123

The MMSZ5238B is a Zener diode. It provides stable voltage regulation. Its nominal Zener voltage is 8.7 volts. This voltage is crucial for protecting circuits. It prevents voltage spikes from damaging sensitive parts. The tolerance on this voltage is tight. It is typically ±5%. You get reliable performance. The diode handles a power dissipation of 500 milliwatts. This power rating is important. It shows how much energy the diode can safely absorb. You must consider heat buildup. The SOD123 surface-mount package is very compact. Its small size saves valuable board space. This package is common in modern electronics. The maximum thermal resistance is 200°C/W. This number tells you how well heat moves away from the diode. Lower numbers are better. It connects the junction temperature to the ambient air. Proper heat management is essential. The diode operates within a wide temperature range. The junction temperature can go from -65°C to +150°C. This makes it suitable for many environments. Storage temperature is also -65°C to +175°C. Handle it carefully during assembly. Avoid excessive heat during soldering. Follow recommended soldering profiles. This prevents damage to the component. Use it for voltage clamping tasks. It works well in voltage reference circuits. It protects inputs from overvoltage events. Its small size fits densely packed designs. Check the forward voltage drop too. It is around 1.5 volts at 20mA forward current. This matters if current flows the normal way. Reverse leakage current is very low. It is typically 100 nanoamperes at 5 volts. This minimizes power loss when blocking. Always refer to the official datasheet. Confirm all specifications for your specific application. Design your circuit carefully. Ensure adequate power derating. Keep the operating temperature well below the maximum.

Applications of MMSZ5238B DIODE ZENER 8.7V 500MW SOD123

The MMSZ5238B is a Zener diode. It regulates voltage at 8.7 volts. This specific voltage point is useful in many circuits. You need stable voltage references. This diode provides that. Its 500mW power rating handles common low-power tasks. The SOD123 surface-mount package is very small. It saves valuable board space in modern electronics.

One key job is voltage regulation. Sensitive circuits need protection from overvoltage. This diode clamps the voltage to 8.7V. It prevents damage to components downstream. Place it across the power supply line. It activates if the voltage spikes above 8.7V. It safely shunts excess current to ground.

Another important use is surge protection. Electronic devices face voltage transients. These spikes come from power lines or static discharge. The MMSZ5238B acts as a barrier. It absorbs or diverts these sudden energy surges. It protects integrated circuits and other delicate parts. This is vital for reliable operation.

It also works in signal clipping circuits. Waveforms sometimes need shaping. This diode can clip off signal peaks exceeding 8.7V. This modifies the waveform for specific needs. It creates squarer signals from sine waves.

You find this diode protecting inputs and outputs. It guards microcontrollers, sensors, and communication ports. Its fast response time catches quick transients. Its small SOD123 size fits almost anywhere. Designers choose it for its reliable 8.7V breakdown and compact form. It’s common in power supplies, consumer gadgets, and automotive modules.
