Overview
The Microchip Technology 1N5352AE3/TR8 is a silicon Zener diode with a nominal voltage of 15V and a tolerance of ±10%. It features a maximum power dissipation of 5W at 25°C, operating within a temperature range of -65°C to +150°C. The device utilizes an axial-lead T-18 package and includes the e3 suffix for RoHS compliance and TR8 suffix for tape-and-reel packaging.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and exhibits minimal voltage change versus current
- Features flexible axial-lead mounting terminals suitable for through-hole applications
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement systems
Procurement Notes
Verify the specific ordering suffixes against official Microchip documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the component meets all required environmental standards and thermal management specifications for the intended application environment before finalizing procurement.
Selection Notes
Select this component based on its 5W power rating and 15V breakdown voltage requirements. Consider the thermal resistance characteristics and derating curves when designing heat sinking solutions. Verify compatibility with existing circuit layouts due to the specific T-18 package dimensions and lead spacing.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options indicated by suffix letters.
Replacement Considerations
Surface mount equivalents are available as SMBJ5352A or SMBG5352A. Direct pin-to-pin replacements should be verified against updated datasheets to ensure identical electrical parameters and mechanical fit.
