1N5352E3/TR8

Overview

The Microchip Technology 1N5352E3/TR8 is a silicon unidirectional 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 RoHS compliance indicated by the e3 suffix.

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 for through-hole integration

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 suffix against official documentation to confirm tape-and-reel packaging and RoHS compliance status. Confirm that the component matches the JEDEC registered series specifications before procurement.

Selection Notes

Select this component when a 15V reference with ±10% tolerance is required. Ensure adequate heat sinking is provided to maintain operation within the 5W power dissipation limit and verify thermal resistance requirements for the specific mounting configuration.

Part Context

This part belongs to the 1N5333B through 1N5388B series of 5-watt silicon 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.

Replacement Considerations

Surface mount equivalents are available as SMBJ5352AE3 or SMBG5352AE3. Verify pinout compatibility and thermal performance when transitioning between axial lead and surface mount packages.
