1N5253B Description

Short technical summary and product information.

The 1N5253B from ON Semiconductor is a 25V Zener diode with a maximum power dissipation of 500mW. It features a ±5% voltage tolerance and a Zener impedance of 35Ω. The reverse leakage current is typically 100nA at 19V, making it suitable for low-power voltage regulation and reference applications.

 

This device is housed in a through-hole DO-35 (DO-204AH) axial lead package, allowing for reliable mounting on printed circuit boards. It operates over a wide temperature range of -65°C to 200°C, ensuring stable performance in demanding environments.

 

Designed for voltage clamping, overvoltage protection, and precision voltage reference circuits, the 1N5253B offers good thermal stability and low noise characteristics. Its compact form factor and compatibility with standard soldering processes make it a practical choice for consumer electronics and industrial control systems.
