Specification of MMSZ3V3ET1 DIODE ZENER 3.3V 500MW SOD123

This diode is the MMSZ3V3ET1. It’s a Zener diode. Its main job is voltage regulation. It keeps a steady voltage at 3.3 volts. This specific voltage is its Zener voltage. It handles up to 500 milliwatts of power. This power rating is crucial. It tells you the maximum energy it can safely dissipate. The SOD123 surface-mount package houses it. This package is very common. It’s small and fits easily onto circuit boards.

You’ll find this diode useful in many circuits. It protects sensitive parts from voltage spikes. It provides a stable reference voltage. It clamps voltage levels. The voltage tolerance is tight. It’s typically within ±5% of 3.3V. This accuracy is important for reliable performance. The maximum leakage current is low. It’s only 5 microamps at 1 volt reverse bias. This low leakage saves power.

The diode handles heat well. Its thermal resistance is 300 degrees Celsius per watt. This value shows how effectively heat moves from the junction to the air. The operating temperature range is broad. It works from -65 degrees Celsius up to +150 degrees Celsius. This range suits many environments. Storage temperatures match this range.

The SOD123 package is compact. It has two leads. It’s designed for automated assembly. The part number MMSZ3V3ET1 identifies it clearly. You see this marking on the device itself. This diode is a solid choice for basic 3.3V regulation needs. Its combination of voltage, power, and package is dependable.

Applications of MMSZ3V3ET1 DIODE ZENER 3.3V 500MW SOD123

This MMSZ3V3T1G diode gives a steady 3.3 volts. It’s a Zener diode. It works backwards. Normal diodes block reverse current. This one lets specific reverse current flow at its breakdown voltage. That voltage is 3.3 volts precisely. It handles up to 500 milliwatts of power. The SOD123 package is small. It fits easily on circuit boards.

Its main job is protecting circuits. Sensitive parts can break if voltage spikes happen. This diode stops that. It connects between the signal line and ground. Normal voltages pass through fine. If voltage jumps above 3.3 volts, the diode activates. It pulls the extra voltage down to ground. This clamps the voltage at 3.3V. It shields components like inputs on microchips.

It’s also great as a voltage reference. Some circuits need a fixed voltage to compare against. This diode provides that stable 3.3V point. It’s used in power supplies or measurement tools. The voltage stays constant even if input power changes a bit. This stability is important.

You see it in power supplies too. It helps make clean, regulated DC power. It might set the output voltage level. It can protect the regulator chip itself. It ensures the output doesn’t go too high.

This diode suits battery-powered things well. Its low power needs help save energy. The small SOD123 size fits tight spaces. Think mobile phones, tablets, sensors. It protects USB ports or memory chips. It sets bias points in radios. It provides reference voltages in simple sensors. It’s reliable and cheap. Engineers pick it for many 3.3V tasks. It offers solid protection and a stable reference point.

5 FAQs of MMSZ3V3ET1 DIODE ZENER 3.3V 500MW SOD123

What is the MMSZ3V3ET1 diode used for?
It protects circuits from overvoltage. It keeps the voltage steady at 3.3 volts. Use it for voltage regulation. Use it to shield sensitive electronic parts from voltage spikes.

How accurate is the 3.3V Zener voltage?
The voltage is not perfectly exact. It can vary. Check the datasheet for the tolerance. The tolerance is usually around ±5%. This means the actual voltage could be between 3.135V and 3.465V. Account for this in your design.

Can it handle more than 500mW power?
No. 500 milliwatts is its maximum rating. Exceeding this damages the diode. Ensure the current through the diode stays low enough. Calculate the power: Power = Zener Voltage x Current. Keep power below 500mW always. Good heat sinking helps.

Does it leak current when off?
Yes. A tiny current flows even below the breakdown voltage. This is called leakage current. The leakage is very small, typically nanoamps. It is usually negligible for most uses. Check the datasheet for exact leakage specs at your operating voltage.

Does temperature affect its performance?
Yes. Temperature changes the Zener voltage slightly. The voltage coefficient tells you how much. For this diode, expect small shifts. Higher temperatures usually mean a higher voltage. Consider temperature effects in precision circuits. The SOD123 package size influences heat dissipation.
