The SZMMBZ5249BLT1G is a 19V Zener diode from onsemi, part of the MMBZ52xxBLT1G series. It offers a nominal Zener voltage of 19V with ±5% tolerance and a maximum power dissipation of 225mW on FR-5 board. The device is designed for voltage regulation in space-constrained applications, featuring a compact SOT-23-3 surface mount package. Electrical characteristics include a maximum Zener impedance of 23Ω, reverse leakage current of 100nA at 14V, and forward voltage of 900mV at 10mA. The diode operates over a junction temperature range of -65°C to 150°C and has thermal resistance of 556°C/W on FR-5 board and 417°C/W on alumina substrate. The SZ prefix indicates automotive qualification per AEC-Q101, and the device is Pb-Free, Halogen Free, and RoHS compliant. It features an ESD rating of greater than 16kV per the Human Body Model, enhancing robustness in handling and operation.
