BZX584C3V9Q

Diodes - Zener - Single

Zener diode3.9 VSOD523AEC-Q101automotive

BZX584C3V9Q is a 3.9 V nominal Zener diode in SOD523, tested at 5 mA and rated for 250 mW dissipation at 25 °C.

Best for

  • General voltage regulation
  • Compact automotive electronic circuits

Avoid if

  • The circuit requires a tightly regulated voltage without accounting for Zener tolerance and dynamic impedance
  • Power dissipation exceeds the thermally derated package limit

Check before use

  • Operating current and regulation voltage
  • PCB footprint and cathode orientation
  • Ambient-temperature power derating
  • Supplier lifecycle and availability
