SMA5931B product

SMA5931B

Diodes - Zener - Single

Zener Diode18V1.5WSMA

The SMA5931B is a 1.5W, 18V surface-mount Zener diode in a DO-214AC (SMA) package, designed for voltage stabilization and clipping applications.

Best for

  • Voltage regulation
  • Signal clipping
  • Transient protection

Avoid if

  • Applications requiring extremely low power dissipation
  • Space-constrained designs where smaller packages like SOD-123 are required

Check before use

  • Thermal derating curve at operating temperatures above 75°C
