1N5365B/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5365B/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 36 V with a ±5% tolerance, indicated by the B 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 11 Ohms and a maximum reverse current of 0.5 µA.

Single Zener Diodes 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

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify component authenticity and datasheet revision status before procurement. Confirm that the TR8 suffix corresponds to tape and reel packaging per EIA-296 standards. Ensure the specific lot meets required environmental screening levels if applicable to the design specifications.

Single Zener Diodes Selection Notes

Select this component when a 36 V regulation point with tight ±5% tolerance is required. The 5 W power dissipation rating supports high-current applications provided adequate heat sinking is implemented. Verify thermal resistance requirements against the intended mounting method on FR4 PCBs or direct lead attachment.
