Overview
The Microchip Technology 1N5357CE3/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 20 volts and a ±2% tolerance. It operates within a temperature range of -65°C to +150°C, features a maximum reverse current of 0.5 µA at 14.4V, and has a dynamic impedance of 3.0 ohms. The component utilizes an axial-lead T-18 package and is supplied in tape and reel format.
Feature Summary
- Provides precise voltage regulation with tight manufacturing tolerances
- Capable of handling high surge stresses and steady-state power dissipation
- Features flexible axial-lead mounting terminals for through-hole applications
Applications
- Voltage regulation circuits requiring stable reference voltages
- Power supply protection against overvoltage conditions
- General-purpose electronic equipment utilizing axial-lead components
Procurement Notes
Verify the specific suffix configuration when ordering to ensure correct tolerance and packaging. Confirm RoHS compliance status as indicated by the e3 designation. Check manufacturer documentation for any updates regarding lead times or discontinuation notices before finalizing procurement plans.
Selection Notes
Select this component for applications requiring a 20-volt reference with high precision. Ensure adequate heat sinking is provided to maintain performance within the specified thermal limits. Verify that the operating current remains within the tested parameters defined in the electrical characteristics table.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The 'C' suffix indicates a tighter ±2% voltage tolerance compared to standard variants. The 'e3' suffix denotes RoHS compliance, while 'TR8' specifies the tape and reel packaging format.
Replacement Considerations
Compatible substitutes include other 1N5357 variants with matching voltage ratings. Ensure replacement parts maintain the required ±2% tolerance and 5-watt power dissipation capabilities. Verify that the physical T-18 package dimensions are compatible with existing board layouts.
