The 1SMB5937BT3G is a 3W plastic surface mount Zener voltage regulator diode from onsemi (formerly On Semiconductor). This device offers a nominal Zener voltage of 33V with ±5% tolerance and a maximum Zener impedance of 33Ω at test current. It is designed for general purpose voltage regulation and overvoltage protection applications.
Key electrical characteristics include a reverse leakage current of 1 µA at 25.1V reverse voltage, a forward voltage of 1.5V at 200mA, and an ESD rating of Class 3 (>16 kV) per Human Body Model. The device can dissipate up to 3W steady state at a lead temperature of 75°C (zero lead length), with a junction-to-lead thermal resistance of 25°C/W and junction-to-ambient thermal resistance of 226°C/W on standard FR-4 board.
The 1SMB5937BT3G is housed in a surface mount DO-214AA (SMB) package with modified L-bend leads for improved solder joint reliability. The case is flame retardant rated UL 94 V-0 and compatible with lead-free soldering processes (260°C for 10 seconds maximum). The device is Pb-free and RoHS compliant, with an operating temperature range of -65°C to +150°C. Tape and reel packaging is standard with 2500 units per reel.
