1N5372AE3/TR12

Overview

The Microchip Technology 1N5372AE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by Microsemi. It provides voltage regulation at a nominal Zener voltage of 62 V with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 42 Ohms and a maximum reverse current of 0.5 µA. The component is RoHS compliant (e3 suffix) and supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack

Applications

• Voltage regulation circuits requiring 5W power dissipation
• Power supply protection against overvoltage conditions
• Reference voltage generation in electronic systems

Procurement Notes

Verify the specific suffix configuration to ensure correct voltage tolerance and compliance status. Confirm that the 'TR12' designation matches the required tape and reel packaging specifications for automated assembly processes. Cross-reference the manufacturer part number with official datasheets to validate electrical parameters before integration into designs.

Selection Notes

Select this component when a 62 V Zener voltage with ±10% tolerance is required for 5W applications. Ensure adequate heat sinking is provided to maintain operation within the specified thermal limits. Consider the T-18 package dimensions for PCB layout constraints and verify compatibility with the intended operating temperature range of -65°C to +150°C.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes produced by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters. These plastic encapsulated diodes are designed for high DC currents and feature low thermal resistance.

Replacement Considerations

Equivalent parts within the 1N5333-5388B series may be considered if voltage tolerance and power ratings match. Verify mechanical dimensions and terminal plating compatibility for direct replacement.
