TVS - Diodes

TVS Diode500WUnidirectionalDO-15

The SA33A is a 500W unidirectional TVS diode from Littelfuse, optimized for protecting sensitive circuits against voltage transients.

Best for

  • I/O interface protection
  • VCC bus protection
  • Telecom and industrial circuits

Avoid if

  • Bidirectional protection is required (use SA33CA instead)

Check before use

  • Verify the peak pulse power and current ratings against the expected transient energy levels.
