Diodes

Zener Diode1.5W51VSMA

The 1SMA5942A is a 1.5W, 51V Zener diode in an SMA (DO-214AC) surface-mount package, designed for voltage regulation and surge protection.

Best for

  • Voltage regulation
  • Surge protection
  • General-purpose clamping

Avoid if

  • Applications requiring extremely low leakage current below 1µA
  • Space-constrained designs where SMA is too large

Check before use

  • Lead temperature derating
  • Maximum forward current limits
