The 1SMB5915BT3G is a 3.9V Zener voltage regulator diode from On Semiconductor's 1SMB59xxBT3G series. It is designed for 3W power dissipation at a lead temperature of 75°C, with a maximum steady-state power dissipation of 550mW at 25°C ambient. The device features a zener impedance of 7.5Ω and a reverse leakage current of 25µA at 1V. It offers an ESD rating of Class 3 (>16kV) per the Human Body Model, ensuring robust protection in handling and operation.
This diode is housed in a void-free, transfer-molded plastic DO-214AA (SMB) package with modified L-Bend leads for improved solder contact. It supports surface mount assembly and is rated for operating temperatures from -65°C to 150°C. The leads are corrosion resistant and readily solderable, with a maximum soldering temperature of 260°C for 10 seconds. The package is rated UL 94 V-0 for flammability.
The 1SMB5915BT3G is Pb-Free and RoHS compliant, making it suitable for environmentally sensitive designs. It is commonly used in voltage regulation, overvoltage protection, and reference voltage applications in consumer, industrial, and automotive electronics (note: AEC-Q101 qualification applies to SZ-prefix variants).
The zener voltage is 3.9V.
The power rating is 3W at a lead temperature of 75°C, and 550mW at 25°C ambient.
The package is DO-214AA (SMB), surface mount.
The operating temperature range is -65°C to 150°C.
The datasheet states it is Pb-Free, and the existing database indicates RoHS3 compliance, though this is unverified.
The forward voltage is 1.5V at 200mA.
The ESD rating is Class 3 (>16kV) per the Human Body Model.
