1SMB5918BT3G Description

Short technical summary and product information.

The 1SMB5918BT3G is a 3W plastic surface mount Zener voltage regulator diode from onsemi's 1SMB59xxBT3G series. It provides a nominal Zener voltage of 5.1V with a tolerance of ±5%. This device is designed for voltage regulation and protection in a wide range of electronic circuits.

 

Key electrical characteristics include a Zener impedance of 4Ω, a forward voltage of 1.5V at 200mA, and a reverse leakage current of 5µA at 2V. The diode can operate over a junction temperature range of -65°C to +150°C and is rated for a maximum steady state power dissipation of 3W at a lead temperature of 75°C.

 

The component is housed in a void-free, transfer-molded plastic DO-214AA (SMB) package designed for surface mount assembly. It features a modified L-bend lead form for improved contact area and is marked with a cathode polarity band. The package is rated UL 94 V-0 for flammability.
