The SZ1SMB5931BT3G from On Semiconductor is a surface mount Zener voltage regulator diode designed for general purpose voltage regulation and protection. This diode offers a nominal Zener voltage of 18V with a tolerance of ±5%. It is capable of dissipating up to 3W of power when measured at a lead temperature of 75°C, and 550mW at an ambient temperature of 25°C. The device features a low reverse leakage current of 1µA maximum at 13.7V and a forward voltage of 1.5V maximum at 200mA. The Zener impedance is 12Ω maximum at the test current. Packaged in a DO-214AA (SMB) surface mount package, the diode is suitable for automated assembly. It is AEC-Q101 qualified for automotive applications and has an ESD rating of Class 3 (>16 kV) per the Human Body Model. The operating temperature range spans -65°C to 150°C. The device is lead-free (Pb-Free) and meets UL 94 V-0 flammability rating. Typical applications include voltage regulation, overvoltage clamping, and protection circuits in automotive, industrial, and consumer electronics.
