1N5231B-TR Description

Short technical summary and product information.

The 1N5231B-TR is a 5.1V Zener diode from Vishay Dale, part of the 1N5221 to 1N5267 series of small signal Zener diodes. It offers a nominal Zener voltage of 5.1V with a tolerance of ±5%, making it suitable for voltage regulation and reference applications.

 

Key electrical specifications include a maximum power dissipation of 500mW at ambient temperatures up to 25°C, a maximum Zener impedance of 17Ω at a test current of 20mA, and a low reverse leakage current of 5µA at 2V reverse voltage. The forward voltage is 1.1V maximum at 200mA forward current. The device features a typical temperature coefficient of 0.03%/K for stable operation over temperature.

 

The diode is housed in a DO-35 (DO-204AH) through-hole package with axial leads, suitable for manual and automated insertion. It has a thermal resistance of 300K/W junction-to-ambient and a maximum junction temperature of 175°C. The storage temperature range is -65°C to +175°C.

 

Typical applications include voltage stabilization, overvoltage protection, and reference voltage generation in various electronic circuits.
