1N5259B Description

Short technical summary and product information.

The 1N5259B is a Zener diode from Microchip Technology, part of the 1N5221-1N5281B series of 0.5 watt voltage regulators. It offers a power dissipation of 500 mW and a tolerance of ±5%. The device is designed for through-hole mounting in a DO-35 (DO-204AH) axial-leaded glass package.

 

Electrical characteristics include a forward voltage of 1.5 V at 200 mA, impedance (Zzt) of 80 Ω, and reverse leakage current of 100 nA at 30 V. The operating temperature range spans -65°C to 175°C (TJ), making it suitable for a wide range of environments.

 

This Zener diode is commonly used for voltage regulation and protection in low-power circuits. The DO-35 package allows for easy insertion in through-hole PCB designs. The part is RoHS3 compliant and REACH unaffected, though these compliance claims are unverified.
