SMAJ33A product

SMAJ33A

Transient Voltage Suppressors (TVS)

TVS Diode400WSMA33V

The SMAJ33A is a 400W unidirectional TVS diode in an SMA package, providing robust transient voltage protection for 33V circuits.

Best for

  • General circuit protection
  • I/O interface protection
  • Power supply transient suppression

Avoid if

  • High-energy surge environments exceeding 400W
  • Bidirectional signal lines (requires SMAJ33CA)

Check before use

  • Polarity orientation
  • Thermal derating requirements
