The SZ1SMB5951BT3G is a 3W surface mount Zener voltage regulator diode from On Semiconductor's 1SMB59xxBT3G series. It features a nominal Zener voltage of 120V with ±5% tolerance and a maximum Zener impedance of 380Ω. The device is designed for general purpose voltage regulation and protection applications.
Electrical characteristics include a maximum forward voltage of 900mV at 10mA and a reverse leakage current of 1µA at 91.2V. The diode can dissipate up to 3W at a lead temperature of 75°C (zero lead length) and 550mW at 25°C ambient on an FR-4 board. It operates over a junction temperature range of -65°C to 150°C.
The part is housed in a DO-214AA (SMB) package with a modified L-bend lead style for improved solder joint contact. It is rated for ESD Class 3 (>16kV) per the Human Body Model and has a UL 94 V-0 flammability rating. The SZ prefix indicates automotive qualification (AEC-Q101) and PPAP capability.
