The SZMMBZ5262BLT1G from the SZMMBZ52xxBLT1G series is a 51V Zener voltage regulator diode in a surface mount SOT-23 package. It offers a nominal Zener voltage of 51V with ±5% tolerance and a maximum power dissipation of 225mW on FR-5 board (derated 1.8 mW/°C above 25°C). The device features a maximum impedance of 125 Ω at the Zener test current and a forward voltage of 900 mV at 10 mA. Reverse leakage current is limited to 100 nA at 39 V.
The operating and storage junction temperature range spans -65°C to +150°C. Thermal resistance junction-to-ambient is 556°C/W on FR-5 board and 417°C/W on alumina substrate. The diode is rated for ESD protection exceeding 16 kV (Human Body Model, Class 3) and carries a flammability rating of UL 94 V-0.
Designed for automated assembly, the SOT-23 package has a corrosion-resistant finish and cathode polarity band. The SZ prefix indicates automotive qualification (AEC-Q101 compliant) and PPAP capability. The component is Pb-Free, Halogen Free/BFR Free, and RoHS3 compliant.
