1SMB5938BT3G Description

Short technical summary and product information.

The 1SMB5938BT3G is a 36V Zener diode from On Semiconductor's 1SMB59xxBT3G series, designed for voltage regulation in surface mount applications. It offers a nominal Zener voltage of 36V with ±5% tolerance and a maximum steady-state power dissipation of 3W at lead temperature 75°C (derated to 550mW at ambient 25°C on FR-4 board). The device features a low Zener impedance of 38Ω at test current and a reverse leakage current of 1µA at 27.4V.

 

This Zener diode is housed in a void-free, transfer-molded plastic DO-214AA (SMB) package with modified L-bend leads for reliable surface mounting. It is rated for operating temperatures from -65°C to +150°C and has a flammability rating of UL 94 V-0. The cathode is indicated by a polarity band.

 

Typical applications include voltage regulation, overvoltage protection, and reference voltage generation in power supplies, automotive electronics, and industrial control systems. The device is Pb-Free and RoHS3 compliant.
