1N5356/TR8

Overview

The Microchip Technology 1N5356/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 19V and a standard tolerance of ±5%. The device features a T-18 axial lead package, operates within a temperature range of -65°C to +150°C, and includes a TR suffix indicating tape and reel packaging.

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
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

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

Procurement Notes

Verify the specific electrical characteristics against the official datasheet before integration. Confirm that the tape and reel packaging aligns with automated assembly requirements. Ensure thermal management strategies account for the specified power dissipation limits at elevated temperatures.

Selection Notes

Select this component when a 5-watt power rating and 19V regulation point are required. Consider the ±5% tolerance for general-purpose applications. Evaluate the thermal resistance specifications to ensure adequate heat sinking for steady-state operation.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage range from 3.3V to 200V with various tolerance options identified by suffix letters.

Replacement Considerations

Equivalent parts include other 5W Zener diodes with 19V nominal voltage and ±5% tolerance. Verify pinout compatibility and thermal performance characteristics when substituting.
