1N5366B Description

Short technical summary and product information.

The 1N5366B is a 5W Zener diode from On Semiconductor, part of the 1N53 series. It offers a nominal zener voltage of 39V with a tolerance of ±5%, making it suitable for voltage regulation applications. The device features a low zener impedance of 14 Ω at the test current, and a forward voltage of 1.2V at 1A. With a maximum reverse leakage current of 500 nA at 29.7V, it ensures stable operation.

 

This diode is designed for through-hole mounting in an axial lead T-18 case. It can handle a maximum power dissipation of 5W and operates over a wide temperature range from -65°C to 200°C. The device also offers an ESD rating of Class 3 (>16 kV) per HBM and a surge power rating of 180W at 8.3 ms, providing robust performance in transient conditions.

 

Typical applications include voltage clamping, regulation, and protection circuits in power supplies and industrial electronics. The axial package allows for easy insertion in printed circuit boards. The RoHS3 compliant version is available, though compliance should be verified.
