1SMB5914BT3G

The 1SMB5914BT3G is a 3.6V Zener diode from On Semiconductor, part of the 1SMB59xxBT3G series of 3W plastic surface mount Zener voltage regulators. It offers a nominal Zener voltage of 3.6V with a tolerance of ±5%, and a maximum power dissipation of 3W at a lead temperature of 75°C. The device is designed for voltage regulation and overvoltage protection in a wide range of electronic circuits.

With a Zener impedance of 9Ω and a reverse leakage current of 75µA at 1V, this diode provides stable and efficient voltage clamping. It also features a forward voltage of 1.5V at 200mA. The device is rated for ESD protection up to Class 3 (>16 kV) per Human Body Model, making it robust for handling during assembly.

Packaged in a DO-214AA (SMB) surface mount package, the diode has a modified L-bend lead style and is supplied in tape and reel packaging (2500 units per reel). The operating temperature range spans -65°C to 150°C, suitable for harsh environments. The thermal resistance from junction to lead is 25°C/W and from junction to ambient is 226°C/W on a standard FR-4 board.

The 1SMB5914BT3G is Pb-free and RoHS compliant, with a flammability rating of UL 94 V-0. It is a reliable choice for voltage regulation in consumer, industrial, and automotive applications (automotive qualified versions are available with SZ prefix).
