The 1SMB5919BT3G from On Semiconductor is a 3W plastic surface mount Zener voltage regulator diode. It features a nominal Zener voltage of 5.6V with ±5% tolerance and low Zener impedance of 2Ω. The device is rated for 3W power dissipation at a lead temperature of 75°C, and 550mW at ambient temperature of 25°C on an FR-4 board. It offers an ESD rating of Class 3 (>16 kV) per Human Body Model. Operating temperature range is -65°C to +150°C. The package is a void-free, transfer-molded plastic DO-214AA (SMB) case with a modified L-Bend lead design. The part is Pb-Free and flammability rated UL 94 V-0.
The nominal Zener voltage is 5.6V with ±5% tolerance.
Maximum steady state power dissipation is 3W at lead temperature 75°C (derate 40mW/°C above 75°C). At 25°C ambient on FR-4 board, power is 550mW.
It is packaged in a surface mount DO-214AA (SMB) case.
Operating and storage temperature range is -65°C to +150°C.
The datasheet states the device is Pb-Free. RoHS compliance is unverified but the part is considered RoHS3 compliant in the database.
