The 1SMB5947B-13 is a 3W surface mount Zener diode from Diodes Incorporated, part of the 1SMB5920B-1SMB5956B series. It features a nominal Zener voltage of 82V with a ±5% tolerance. The device is designed for automated assembly and offers a power dissipation of 3W at a terminal temperature of +75°C, and 550mW at +25°C ambient temperature on FR-4 PCB.
Electrical characteristics include a maximum forward voltage of 1.5V at 200mA, a maximum reverse leakage current of 1µA at 62.2V, and a maximum Zener impedance of 160Ω at IZT. The diode is rated for ESD protection per Human Body Model with Class 3 performance (>16kV). It operates over a junction temperature range of -65°C to +150°C with thermal resistance of 25°C/W junction-to-terminal and 226°C/W junction-to-ambient on standard PCB.
The diode is housed in a surface-mount DO-214AA (SMB) package with molded plastic case material rated UL 94V-0. The termination is matte tin finish, solderable per MIL-STD-202. It is supplied in tape and reel packaging with 3000 units per reel. The device is RoHS3 compliant, halogen and antimony free, and has MSL Level 1 moisture sensitivity per J-STD-020.
