1N5337/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5337/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 4.7 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 plastic encapsulated axial-lead package. The TR8 suffix denotes tape and reel packaging compliant with EIA-296 standards.
