1SMB5927B

Diodes - Zener - Single

Zener Diode1.5W12VSMB

The 1SMB5927B is a 1.5W Zener diode with a 12V nominal voltage and 5% tolerance, suitable for general-purpose voltage regulation in surface-mount applications.

Best for

  • Voltage regulation
  • Transient voltage suppression

Avoid if

  • Applications requiring power dissipation significantly exceeding 1.5W
  • Extremely space-constrained designs where smaller packages like SOD-123 are required

Check before use

  • Lead temperature at the mounting point
  • Derating requirements at high ambient temperatures
