1N5356AE3/TR8

Overview

The Microchip Technology 1N5356AE3/TR8 is a silicon Zener diode with a nominal voltage of 19 V and a power dissipation rating of 5 W. It features a ±10% voltage tolerance, indicated by the 'A' suffix, and RoHS compliance via the 'e3' suffix. The device utilizes a T-18 axial lead package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum reverse current of 0.5 µA at 13.7 V and a dynamic impedance of 3.0 Ω.

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 component authenticity against official Microchip documentation. Confirm that the e3 suffix indicates lead-free RoHS compliance and the TR8 suffix denotes tape and reel packaging. Ensure the specific lot matches the required JEDEC registration standards for the 1N5356 series.

Selection Notes

Select this component when a 19 V reference with 5 W power handling is required. The A suffix provides standard 10% tolerance suitable for general applications. Consider thermal derating curves if ambient temperatures exceed 25°C or if mounted on FR4 PCBs without adequate copper pads.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip). The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters.

Replacement Considerations

Compatible substitutes include the 1N5356A/TR8 and 1N5356AE3. Verify that replacement parts maintain the same 19 V nominal voltage, 5 W power rating, and T-18 package dimensions.
