SZBZX84B18LT1G Description

Short technical summary and product information.

SZBZX84B18LT1G is a Zener voltage regulator diode from On Semiconductor, part of the SZBZX84BxxxLT1G series. It is designed for voltage regulation in surface mount applications requiring compact size and reliable performance. Key specifications include a nominal zener voltage of 18V, power dissipation of 225mW, maximum impedance of 45Ω, reverse leakage current of 50nA at 12.6V, and forward voltage of 900mV at 10mA. The device operates over a junction temperature range of -65°C to 150°C. The package is SOT-23-3 (also known as TO-236-3 and SC-59), surface mount, suitable for automated assembly. It is available in tape and reel packaging with 3000 units per reel. Compliance includes RoHS3, Pb-Free, REACH unaffected, and MSL 1 (unlimited). The SZ prefix indicates automotive qualification (AEC-Q101) and PPAP capability. Applications include voltage regulation in cellular phones, handheld portable devices, and high-density PCBs.
