The SZ1SMB5941BT3G is a 3W plastic surface mount zener voltage regulator diode from On Semiconductor's 1SMB59xxBT3G series. It offers a nominal zener voltage of 47V with ±5% tolerance. This diode is designed for general purpose voltage regulation and reference applications.
Key electrical specifications include a maximum forward voltage of 1.5V at 200mA, maximum reverse leakage current of 1μA at 35.8V, and a maximum zener impedance of 67Ω. The device is rated for continuous power dissipation of 3W measured at lead temperature 75°C, derating linearly above that temperature. At ambient temperature 25°C on FR-4 PCB, the dissipation rating is 550mW.
The device is housed in a DO-214AA (SMB) surface mount package with modified L-bend leads. It features an ESD rating of Class 3 (>16kV) per Human Body Model, and is rated for operating and storage temperatures from -65°C to 150°C. The SZ prefix indicates automotive qualification (AEC-Q101) and PPAP capability.
