The MM3Z43VB is a Zener diode from On Semiconductor offering a nominal Zener voltage of 43V with a tolerance of ±2%. It is rated for a maximum power dissipation of 200mW, making it suitable for low-power voltage regulation and protection applications. The device features a forward voltage of 1V at 10mA and a low reverse leakage current of 45nA at 30.1V. The maximum Zener impedance at the test current is 141Ω.
The diode is designed for surface mount assembly in a compact SOD-323F package (SC-90 case). It operates over a wide temperature range from -65°C to 150°C, with a maximum junction temperature of 150°C. The thermal resistance from junction to ambient is 595°C/W, which should be considered for power dissipation in high-temperature environments.
Typical applications include voltage reference, overvoltage clamping, and protection circuits in consumer, industrial, and automotive electronics where space is limited. The Pb-free and RoHS-compliant finish supports lead-free soldering processes.
