1N5366B/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5366B/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation in axial-leaded T-18 packages. It provides a nominal Zener voltage of 39 V with a ±5% tolerance and operates within a temperature range of -65°C to +150°C. The device features a maximum reverse current of 0.5 µA at 28.1 V and a dynamic impedance of 14 Ω at a test current of 30 mA. Packaged in tape and reel format per EIA-296 standards, it supports high surge currents and withstands significant thermal stress when adequately heat sunk.
