Product details

Package, mounting, and tape-and-reel packaging

The 1.5SMCJ20CA: The DO-214AB (SMC) is a standard 2-pin J-lead surface-mount package — compatible with standard SMT assembly and reflow profiles, with a copper die-attach tab that also serves as the primary thermal path; Tape & Reel (TR) packaging is standard for high-volume assembly.

Active production status and sourcing posture

For BOM planners, this means a new-design commitment carries low lifecycle risk, though independent-distribution quotes should still confirm current date-code availability at RFQ.

Frequently asked questions

How can I source 1.5SMCJ20CA and get a current price?

No stock-holding commitment is made on this listing.

What type of protection does the 1.5SMCJ20CA provide?

The 1.5SMCJ20CA is a bidirectional Zener TVS diode — it clamps voltage transients by avalanche breakdown above its 22.2 V minimum breakdown, limiting the protected node to 32.4 V at the peak surge current of 46.3 A, making it suitable for protecting downstream circuits on 20 V-class rails.
