The On Semiconductor SZ1SMB5918BT3G is a 3W surface mount Zener voltage regulator diode. It offers a nominal Zener voltage of 5.1V with a tolerance of ±5%. The device is designed for general purpose voltage regulation and protection applications. It is housed in a DO-214AA (SMB) surface mount package, featuring modified L-Bend leads for improved solder joint reliability. Key electrical characteristics include a maximum Zener impedance of 4Ω at the test current, a maximum reverse leakage current of 5µA at 2V, and a maximum forward voltage of 1.5V at 200mA. The device operates over a junction temperature range of -65°C to 150°C. It has an ESD rating of Class 3 (>16kV) per the Human Body Model and is rated UL 94 V-0 for flammability.
