1N5335C/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5335C/TR12 is a silicon unidirectional voltage regulator diode belonging to the JEDEC registered 1N5333B through 1N5388B series. It features a nominal Zener voltage of 3.9 V with a tight tolerance of ±2%, indicated by the C suffix. The device is rated for a maximum power dissipation of 5.0 watts and operates within a temperature range of -65°C to +150°C. Packaged in a T-18 axial lead format, it utilizes a void-free transfer molded thermosetting epoxy body. The TR suffix designates tape and reel packaging compliant with EIA-296 standards.
