The On Semiconductor SZ1SMB5953BT3G is a 3-watt plastic surface mount Zener voltage regulator diode designed for general-purpose voltage regulation and protection applications. It offers a nominal Zener voltage of 150V with a ±5% tolerance, making it suitable for precise voltage clamping and reference circuits.
This device is rated for a maximum steady-state power dissipation of 3W at a lead temperature of 75°C, with derating above that temperature. At an ambient temperature of 25°C on an FR-4 board with the recommended footprint, the power dissipation is 550mW. The diode also features a maximum forward voltage of 1.5V at 200mA and a low reverse leakage current of 1µA at 114V.
The SZ1SMB5953BT3G is housed in a DO-214AA (SMB) surface mount package with a modified L-bend lead design for improved solder joint reliability. It is AEC-Q101 qualified for automotive applications and has an ESD rating of Class 3 (>16kV) per the Human Body Model. The device is Pb-free and has a flammability rating of UL 94 V-0.
