Product details

Transient protection for 45V rails

Its 50V minimum breakdown voltage and 72.7V maximum clamping at 20.6A (10/1000µs pulse) define the protection envelope for downstream silicon.

Active status and sourcing position

Sourced per RFQ — confirm current lead time and price breaks for your BOM quantity.

Housed in the DO-214AB (SMC) surface-mount package, rated for -65°C to 150°C junction temperature. The wide temperature range suits outdoor telecom cabinets, industrial motor drives, and automotive aftermarket modules where ambient heat is high.

Frequently asked questions

Is SMCJ45CAE3/TR13 bidirectional?

Yes, it has one bidirectional channel, clamping transients of either polarity symmetrically. Use it on AC lines, bipolar supplies, or data lines where the signal swings through zero.

What is the difference between SMCJ45CAE3/TR13 and SMCJ45A?

The 'C' in the order code indicates bidirectional clamping; SMCJ45A is unidirectional. Both are 1500W parts in the same DO-214AB package. Choose bidirectional for AC or bipolar circuits, unidirectional for single-polarity rails.
