1N5370B Description

Short technical summary and product information.

The 1N5370B is a Zener voltage regulator diode from Microsemi, part of the 1N53 series. It offers a nominal Zener voltage of 56V with a tolerance of ±5%, making it suitable for precise voltage reference and regulation applications. The device is rated for a maximum steady-state power dissipation of 5W at 25°C (lead temperature 3/8 inch from case), with a derating factor of 40 mW/°C above 25°C.

 

Key electrical specifications include a maximum Zener impedance of 35Ω at the test current IZT, a reverse leakage current of 500 nA at 40.3V, and a forward voltage of 1.2V at 1A. The diode also features an ESD rating of Class 3 (greater than 16 kV per Human Body Model) and a non-repetitive surge rating of 180W for 8.3 ms, providing robust protection in transient environments.

 

Mechanically, the 1N5370B is housed in a void-free, transfer-molded thermosetting plastic T-18 axial lead package. It is designed for through-hole mounting with a cathode indicated by a polarity band. The operating temperature range is -65°C to 150°C for DC conditions, with a maximum lead soldering temperature of 260°C for 10 seconds. The device is available in Pb-free packages, compliant with RoHS standards.
