The 1.5SMC33AHE3/9AT: AEC-Q101 qualification means this part is screened for automotive-grade reliability — temperature cycling, high-temperature reverse bias, and ESD robustness per the automotive stress profile.
Clamping voltage and breakdown margin
Unidirectional clamping (single-channel) means the diode conducts in avalanche only on the positive transient; the forward drop handles negative surges. The DO-214AB (SMC) package footprint matches the industry-standard SMCJ land pattern, so the PCB layout is compatible with other 1500 W TVS diodes in the same case size.
Active production and sourcing
Supplied in tape-and-reel packaging (the /9AT suffix), this suits automated pick-and-place assembly. The base product number 1.5SMC33 covers the full family; the AHE3 suffix denotes AEC-Q101 automotive qualification and the TransZorb die design.
