1SMB5927BT3 Description

Short technical summary and product information.

The 1SMB5927BT3 is a 3W surface mount Zener diode from ON Semiconductor, part of the 1SMB59xxBT3 series. It offers a nominal Zener voltage of 12V with ±5% tolerance, making it suitable for voltage regulation and overvoltage protection applications. The device features a maximum Zener impedance of 6.5Ω at the test current, and a reverse leakage current of only 1µA at 9.1V reverse voltage. Forward voltage is a maximum of 1.5V at 200mA forward current.

 

The diode is rated for a maximum steady-state power dissipation of 3W at a lead temperature of 75°C (zero lead length), with a derating of 40mW/°C above 75°C. At an ambient temperature of 25°C on a standard FR-4 board, the power dissipation is 550mW. The thermal resistance from junction to lead is 25°C/W, and from junction to ambient is 226°C/W. Operating and storage temperature range is -65°C to +150°C.

 

The device is packaged in a void-free, transfer-molded plastic DO-214AA (SMB) case with modified L-bend leads, suitable for surface mount assembly. It is rated for ESD Class 3 (>16kV) per the Human Body Model, and has a flammability rating of UL 94 V-0. The maximum lead temperature for soldering is 260°C for 10 seconds. Polarity is indicated by a cathode band.
