SZMM3Z43VT1G Description

Short technical summary and product information.

The SZMM3Z43VT1G is a Zener voltage regulator diode from On Semiconductor, part of the SZMM3ZxxxT1G series. It provides a nominal Zener voltage of 43V with a tolerance of ±7% and a maximum power dissipation of 300mW on an FR-4 board. The device features a maximum impedance of 150Ω and a reverse leakage current of 50nA at 30.1V. Forward voltage is 900mV at 10mA. The diode is housed in a compact SOD-323 (SC-76) surface mount package, weighing 4.507mg. It is designed for voltage regulation in space-constrained applications such as cellular phones, handheld portables, and high-density PCBs. The SZ prefix indicates automotive qualification per AEC-Q101 and PPAP capability. The device is Pb-Free and has an ESD rating of >16kV (Class 3) per Human Body Model. Operating temperature range is -65°C to 150°C. Thermal resistance junction-to-ambient is 416°C/W on a standard FR-4 board.
