The 1SMB5919BT3 is a 3W Zener voltage regulator diode from On Semiconductor, part of the 1SMB59xxBT3 series. It provides a nominal Zener voltage of 5.6V with a tolerance of ±5%. The device features a low maximum Zener impedance of 2Ω at the test current, ensuring stable voltage regulation. Forward voltage is 1.5V at 200mA, and reverse leakage current is 5µA at 3V reverse voltage. The diode is rated for an ESD immunity of >16kV per the Human Body Model, making it robust for harsh environments.
Designed for surface mount assembly, the 1SMB5919BT3 is housed in a DO-214AA (SMB) plastic package with a modified L-bend lead style for reliable solder connections. The package is void-free, transfer-molded plastic with UL 94 V-0 flammability rating. Thermal characteristics include a junction-to-lead thermal resistance of 25°C/W and junction-to-ambient of 226°C/W. Maximum steady state power dissipation is 3W when measured at zero lead length at lead temperature 75°C, derated at 40mW/°C above 75°C. At ambient temperature of 25°C, power dissipation is 550mW.
This Zener diode is suitable for voltage regulation, overvoltage protection, and voltage reference applications in a wide range of electronic equipment. Its operating temperature range spans -65°C to +150°C, accommodating demanding thermal conditions. The device is offered in tape and reel packaging for automated assembly.
