Specification of MMSZ4V3T1 DIODE ZENER 4.3V 500MW SOD123

Here’s the product description for the MMSZ4V3T1 diode. It provides stable 4.3V voltage regulation. This Zener diode is built for protection and regulation tasks. It reliably clamps voltage spikes. It maintains a steady reference voltage. The rated Zener voltage is 4.3V. This is measured at a specific test current (IZT = 20mA). The tolerance is tight, typically ±5%. This ensures predictable circuit performance.

Its maximum power dissipation is 500 milliwatts. This applies at an ambient temperature of 25°C. Power handling decreases as temperature rises. The thermal resistance is 357°C/W. You must consider this for heat management. Exceeding the power limit damages the diode. Always design with sufficient safety margin.

The diode comes in the compact SOD123 surface-mount package. This small size saves valuable board space. It’s ideal for modern, dense electronics. The package offers good thermal performance. It suits automated assembly processes well.

Key electrical specs matter for design. The maximum reverse leakage current is low. It’s only 100nA at the working voltage (VR = 1V). The forward voltage is standard for silicon diodes. Expect around 1V at 10mA forward current (VF). The dynamic impedance (ZZT) is 60 ohms at the test current. This affects regulation sharpness. Lower impedance is generally better.

Operating temperature range is wide. It functions reliably from -65°C to +150°C. This suits demanding industrial environments. Storage temperature matches this range. The diode handles typical soldering conditions. Peak reflow temperatures reach 260°C.

5 FAQs of MMSZ4V3T1 DIODE ZENER 4.3V 500MW SOD123

What does the MMSZ4V3T1 diode do?
This diode keeps voltage steady at 4.3 volts. It acts like a pressure relief valve for electricity. If voltage tries to go above 4.3V, the diode lets extra current flow. This action clamps the voltage down. It protects sensitive parts in your circuit.

What are the main specs?
Its key rating is 4.3 volts Zener voltage. The diode handles 500 milliwatts of power. It uses a SOD123 surface-mount package. This package is small and common for circuit boards.

What package is it in?
The diode comes in a SOD123 package. SOD123 is a standard surface-mount type. It has two leads. The body is rectangular and small. This size fits well on crowded boards.

Where do you use this diode?
Use it for basic voltage regulation. It protects inputs on integrated circuits. It stabilizes voltage references. It guards against voltage spikes. Simple power supplies often need it. It’s good where 4.3V stability matters.

Any handling precautions?
Yes. Watch the polarity. The cathode end is marked with a band. Solder it correctly. Don’t exceed the 500mW power limit. Too much power overheats it. Overheating destroys the diode. Use standard ESD precautions. Static electricity can damage it.
