1SMB5956B-13

The 1SMB5956B-13 is a 3.0W surface mount Zener diode from Diodes Incorporated, offering a nominal Zener voltage of 200V with ±5% tolerance. It is designed for general purpose voltage regulation and protection circuits. The device is housed in a DO-214AA (SMB) package with molded plastic case material rated UL 94V-0, and features a copper alloy leadframe with matte tin plating for excellent solderability.

Key electrical specifications include a maximum impedance of 1200Ω at the Zener test current of 2.5mA, a reverse leakage current of 1µA at 152V, and a forward voltage of 1.5V at 200mA. The component is rated for continuous power dissipation of 3W at a case temperature of +75°C, derating at 40mW/°C above that temperature. At ambient temperature of +25°C, power dissipation is 550mW with a derating of 4.4mW/°C.

The diode has an ESD rating of Class 3 (>16kV) per Human Body Model, making it robust for handling in automated assembly processes. It is RoHS3 compliant, lead-free, halogen and antimony free (Green), and has a Moisture Sensitivity Level of 1 (unlimited). The operating temperature range is -65°C to +150°C. Supplied in tape and reel packaging with 3000 units per reel, the 1SMB5956B-13 is suitable for high-volume surface mount manufacturing.
