1N5224B Description

Short technical summary and product information.

The 1N5224B from On Semiconductor is a unidirectional Zener diode designed for voltage regulation and reference applications. It provides a nominal Zener voltage of 2.8V with a tolerance of ±5%, ensuring reliable clamping and regulation in low-voltage circuits. The device can dissipate up to 500mW of power, making it suitable for low-power protection and biasing tasks.

 

This Zener diode offers a maximum impedance of 30Ω at the Zener test current and features a forward voltage of 900mV at 200mA. Its low reverse leakage current of 50µA at 1V helps maintain efficiency in sensitive designs. The DO-35 axial-lead package supports through-hole mounting and is compatible with standard PCB layouts.

 

Typical applications include voltage regulation in power supplies, overvoltage protection in consumer electronics, and reference voltage generation in analog circuits. The 1N5224B is a through-hole component suitable for prototyping and production in moderate-volume builds.
