DZ23C56-G3-08

Overview

The DZ23C56-G3-08 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 56 V with a standard tolerance of ±5 %. The device operates at a test current of 2 mA and features a maximum reverse leakage current of 50 µA at 42 V. Dynamic resistance is specified at 135 Ω (max) at the test current, with a temperature coefficient ranging from 9 to 11 x 10⁻⁴/°C. Power dissipation reaches 500 mW on leads and 300 mW on FR-4 boards, supporting an operating junction temperature up to 150 °C.
