18 V ZenerSOD-123AEC-Q101500 mWAutomotive

MMSZ5248BQ is an AEC-Q101 qualified 18 V nominal Zener diode in SOD-123, intended for general regulation and voltage-clamping functions.

Best for

  • Automotive-qualified voltage regulation
  • 18 V nominal voltage clamping
  • Compact SOD-123 designs

Avoid if

  • A tightly regulated 18 V output is required across a wide current range
  • Power dissipation can exceed 500 mW at Ta = 25 °C
  • A verified lifecycle status is mandatory

Check before use

  • Zener voltage at the intended operating current
  • Thermal derating above 25 °C ambient
  • Cathode polarity and PCB footprint
  • Reverse leakage at the required reverse voltage
