SZBZX84B27LT1G

SZBZX84B27LT1G Description

The SZBZX84B27LT1G from onsemi is a high-performance 27V Zener diode designed for precision voltage regulation in automotive and surface-mount applications. Packaged in a compact SOT23-3 form factor, it delivers a 225 mW power dissipation with a tight ±2% tolerance on the nominal Zener voltage (Vz), ensuring reliable performance in critical circuits. Its low reverse leakage current (50 nA @ 18.9 V) and optimized forward voltage (900 mV @ 10 mA) make it ideal for low-power designs requiring stable voltage references. The device is RoHS3 compliant, REACH unaffected, and meets automotive-grade reliability standards, making it suitable for harsh environments.
