SZNZ8F18VMX2WT5G Description

Short technical summary and product information.

The SZNZ8F18VMX2WT5G is a 18V Zener diode from On Semiconductor's NZ8F series, designed for voltage regulation in space-constrained applications. It offers a nominal Zener voltage of 18V with ±5% tolerance, a maximum Zener impedance of 50Ω, and a forward voltage of 0.9V at 10mA. The device dissipates up to 250mW on a standard FR-4 board and operates over a junction temperature range of -65°C to 150°C.

 

This Zener diode is housed in a compact X2DFNW surface mount package (2-XDFNW, 1x0.6mm) with wettable flanks, enabling automated optical inspection (AOI). The SZ prefix indicates automotive qualification (AEC-Q101) and PPAP capability, making it suitable for automotive control units and other high-reliability systems.

 

Typical applications include voltage regulation and overvoltage protection in cellular phones, handheld portables, and automotive electronics. The device is supplied in tape and reel packaging with 8000 units per reel, and is RoHS compliant, Pb-Free, and Halogen Free.
