Product details

The base product number SMCJ110 covers a family of unidirectional and bidirectional variants in the same DO-214AB package, so a BOM change between them is a pick-and-place tape change, not a board respin.

Bidirectional clamping — one device for bipolar rails

Power line protection is not specified (the part is not intended for continuous overvoltage clamping on mains), but it handles the 8.4A peak pulse current defined by the 10/1000µs surge waveform, which covers most IEC 61000-4-5 surge test levels on secondary-side circuits.

Frequently asked questions

Where can I buy SMCJ110CAE3/TR13 and how do I get a price?

SMCJ110CAE3/TR13 is available through independent distribution channels. No stock-holding claim is made here.

Is SMCJ110CAE3/TR13 RoHS compliant?

The part is listed as RoHS compliant based on the manufacturer's standard product marking. The /TR13 suffix indicates tape-and-reel packaging; the suffix in the base number typically denotes RoHS and Pb-free termination finish per Microchip's naming convention.

What is the difference between SMCJ110A and SMCJ110CA?

SMCJ110A is the unidirectional version (single-direction clamping) while SMCJ110CA is the bidirectional version (both directions). Both share the same DO-214AB package, 110V standoff, and 1500W rating. The SMCJ110CAE3/TR13 is the bidirectional variant with Pb-free finish and tape-and-reel packaging.

Can SMCJ110CAE3/TR13 be used for 12V surge protection?

No. The reverse standoff voltage is 110V, which is far above a 12V rail. For 12V protection you need a TVS with a standoff voltage near 12V (e.g., SMCJ12A or SMCJ12CA). Using a 110V-rated device on a 12V line will not trigger breakdown until the transient exceeds 122V, leaving the 12V circuitry unprotected.

Is SMCJ110CAE3/TR13 obsolete?

No. The product status is Active. Microchip continues to manufacture this part; there is no EOL notice or last-time-buy window in effect.
