The 1SMB5943B-13 is a 56V Zener diode from Diodes Incorporated, part of the 1SMB59xxB series. It offers a nominal Zener voltage of 56V with ±5% tolerance and a maximum power dissipation of 3.0W at a lead temperature of +75°C. The device features a low forward voltage of 1.5V at 200mA and a maximum Zener impedance of 86Ω at the test current.
Designed for surface mount assembly, the 1SMB5943B-13 is housed in a DO-214AA (SMB) package with a matte tin finish and copper alloy leadframe. It is rated for an operating temperature range of -65°C to +150°C and has a thermal resistance of 226°C/W junction-to-ambient on standard FR-4 PCB. The device also features an ESD rating of >16kV per the Human Body Model, ensuring robust protection in handling and operation.
This Zener diode is RoHS3 compliant, halogen and antimony free, and has a moisture sensitivity level of 1 (unlimited). It is supplied in tape and reel packaging with a standard quantity of 3000 units per reel, making it suitable for automated assembly processes.
