TPSMBJ12CA

TVS - Diodes

TVS diodeBidirectional12 V600 WSMBDO-214AA

TPSMBJ12CA is a 12 V bidirectional SMB TVS diode rated for 600 W 10/1000 µs surge pulses, with 19.9 V maximum clamping at 30.2 A.

Best for

  • Bidirectional transient voltage clamping
  • 12 V standoff protection rails
  • SMB surface-mount protection designs

Avoid if

  • The protected node cannot tolerate a 19.9 V clamp voltage
  • Compliance, qualification, or MSL requirements require documented evidence

Check before use

  • Confirm the actual surge waveform is within the 600 W 10/1000 µs rating
  • Verify PCB footprint against the DO-214AA package drawing
  • Check current distributor availability and compliance documentation
