This document describes the features and characteristics of the BZT03 series voltage regulator diodes, including glass passivated, high maximum operating temperature, low leakage current, and excellent stability. The series includes 38 types with a zener working voltage range of 7.5 to 270V, and 45 types with a transient suppressor stand-off voltage range of 6.2 to 430V.
The document is a product specification sheet for the Philips BZT03 series of discrete semiconductor devices. These are glass passivated voltage regulator diodes available in SOD57 packages with high maximum operating temperatures.
The datasheet details two main applications: use as voltage regulator diodes and use as transient suppressor diodes. It lists specific electrical characteristics such as forward voltage, differential resistance temperature coefficient, and reverse breakdown voltage for various types ranging from C7V5 to C470.
| Forward voltage | 1.2 V max at Ir = 0.5 A |
|---|---|
