Product Description

onsemi 1N5231CTR is a single general purpose Zener diode designed for voltage regulation and protection applications. It is housed in a through hole SOD-27 package with 2 pins, suitable for easy PCB mounting and assembly in electronic circuits.

The diode features a nominal Zener voltage of 5.1 V with a tolerance of ±2 %, making it ideal for precise voltage referencing and stabilization tasks in industrial and consumer electronic devices. With a maximum power dissipation of 500 mW, it can efficiently handle moderate power loads without thermal failure.

It supports a wide operating temperature range from -65°C to 200°C, allowing it to perform reliably in demanding environments such as automotive electronics, industrial controls, and power supplies. The maximum reverse leakage current of only 5 μA ensures minimal current loss and improved circuit efficiency.

The maximum Zener impedance of 17 Ω helps maintain voltage stability under varying current loads, enhancing overall circuit reliability. The compact dimensions (length 4.56 mm, height 1.91 mm) and through hole mounting type make it suitable for versatile PCB designs and manual soldering processes.
