1500 W bidirectional TVS — 18.8 V standoff, DO-214AB
The 1.5SMC22CA-E3/9AT: Breakdown is guaranteed between 20.9 V and the clamp ceiling, so a 24 V supply bus with transients exceeding the rail sees the TVS clamp before the load sees damage.
Package and board-fit — DO-214AB (SMC)
The supplier device package is listed as DO-214AB (SMCJ), confirming the JEDEC-standard outline. The wide TJ window means the TVS maintains its clamping characteristic through thermal cycling — no derating concern at 85°C ambient, though the peak pulse power curve in the datasheet should be consulted for sustained high-temperature operation above 25°C.
Active lifecycle — sourcing posture
The part ships in Tape & Reel (TR) packaging, consistent with the DO-214AB format for automated pick-and-place assembly.
