SMAZ22-13-F

Single Zener Diodes Overview

The SMAZ22-13-F is a 1.0W surface mount Zener diode from Diodes Incorporated, housed in an SMA (DO-214AC) package. It features a nominal Zener voltage of 22V with a standard tolerance of ±5%, ranging from 20.9V to 23.1V. The device operates at a test current of 25mA and exhibits a maximum Zener impedance of 15Ω at the test current and 180Ω at the knee current. Maximum reverse leakage current is specified as 0.5µA at 16.7V. It supports a power dissipation of 1.0W at +50°C, derating by 10mW/°C above this temperature, with an operating and storage temperature range of -65°C to +150°C.
