1N5354E3/TR8

Overview

The Microchip Technology 1N5354E3/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 17 V and a ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 0.5 µA at 12.9 V and a dynamic impedance of 2.5 Ω. The device utilizes an axial-lead T-18 package and includes the e3 suffix for RoHS compliance and TR 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 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 suffixes against official documentation to confirm RoHS compliance and reel packaging specifications. Confirm that the component meets all required electrical tolerances and thermal ratings for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when a 5-watt power dissipation rating and a 17 V nominal breakdown voltage are required. Ensure the design accommodates the specified thermal resistance and allows for adequate heat sinking to maintain operation within the -65°C to +150°C temperature limits.
