PSMB20J58CA

Transient Voltage Suppressors (TVS)

bidirectional TVS58 V2000 WSMBDO-214AARoHSMSL 1

PSMB20J58CA is a bidirectional 58 V SMB TVS diode for transient suppression on circuits exposed to inductive switching or lightning-related surges.

Best for

  • Bidirectional transient suppression on 58 V or lower normal-voltage lines
  • Protection of IC, MOSFET, and sensor signal circuits from inductive switching transients
  • Surface-mount designs using the SMB footprint

Avoid if

  • A unidirectional TVS response is required
  • The protected circuit cannot tolerate up to 93.6 V during the specified 10/1000 µs surge
  • Package thermal capability or surge waveform differs materially from the datasheet test conditions

Check before use

  • Verify the actual surge waveform, repetition rate, and ambient-temperature derating.
  • Confirm PCB copper area and thermal design support the intended surge duty.
  • Check clearance, creepage, and placement near the transient entry point.
