Overview
The Microchip Technology 1N5372CE3/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 62 V and a tight ±2% tolerance. It operates within a temperature range of -65°C to +150°C, features a maximum reverse leakage current of 500 nA, and has a dynamic impedance of 42 Ohms at a test current of 20 mA. The component utilizes a T-18 axial lead 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
- Clamping applications in electronic systems
Procurement Notes
Verify the specific suffix configuration to ensure compliance with required tolerance levels and RoHS standards. Confirm that the tape and reel packaging aligns with automated assembly requirements. Cross-reference the manufacturer's latest documentation to validate electrical characteristics and mechanical dimensions before finalizing procurement specifications.
Selection Notes
Select this component when a 62 V reference with high precision is necessary. The ±2% tolerance distinguishes it from standard variants. Ensure adequate heat sinking is provided to maintain performance within the specified thermal limits during operation.
Part Context
This device 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 the standard B (±5%) or A (±10%) options. The 'e3' suffix denotes RoHS compliance, while 'TR12' specifies the tape and reel packaging format.
Replacement Considerations
Compatible substitutes include other 62 V Zener diodes with similar 5 W power ratings and ±2% tolerance. Verify that alternative components match the T-18 package dimensions and thermal resistance characteristics to ensure seamless integration into existing designs.
