1N5231BTR Description

Short technical summary and product information.

The 1N5231BTR is a Zener diode from ON Semiconductor, part of the 1N5221B-1N5252B series. It features a nominal zener voltage of 5.1V with a ±5% tolerance, tested at 20mA. The maximum power dissipation is 500mW, with a derating of 4mW/°C above 50°C. The device operates over a temperature range of -65°C to 200°C.

This diode is suitable for voltage regulation, clamping, and reference applications in low-power circuits. It offers a low impedance of 17Ω at the test current and a reverse leakage current of 5µA at 2V.

The 1N5231BTR is packaged in a DO-35 (DO-204AH) through-hole axial lead package, making it easy to integrate into PCB designs. The tape and reel packaging (TR suffix) facilitates automated assembly.
