1N5354C/TR8

Overview

The Microchip Technology 1N5354C/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation with a nominal Zener voltage of 17 V and a tight tolerance of ±2%, indicated by the 'C' 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 2.5 Ohms, a maximum reverse current of 500 nA, and a test current of 70 mA.

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 requiring no dry pack

Applications

• Voltage regulation in power supply circuits
• Reference voltage sources for electronic systems
• Overvoltage protection components

Procurement Notes

Verify component authenticity and datasheet revision status upon acquisition. Confirm that the specific part number matches the required electrical parameters, particularly the 17 V Zener voltage and ±2% tolerance associated with the C suffix. Ensure the TR8 tape and reel packaging aligns with automated assembly requirements. Check for any discontinuance notifications or alternative sourcing options due to potential lifecycle changes.

Selection Notes

Select this component when precise voltage regulation is required with tighter tolerances than standard B-suffix devices offer. The 5-watt power dissipation rating supports high-current applications provided adequate heat sinking is implemented. Verify compatibility with the T-18 axial lead package dimensions and ensure the operating environment falls within the specified -65°C to +150°C temperature range.

Part Context

This component belongs to the Microsemi (now Microchip Technology) 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The 1N5354 variant specifically targets the 17 V regulation point. The TR8 suffix indicates the device is supplied in a tape and reel format suitable for high-volume automated placement processes.
