AEC-Q101 qualification and temperature range
The 1.5SMBJ17CA: This part belongs to the Automotive, AEC-Q101, 1.5SMBJ series, meaning it has passed the stress and reliability tests required for automotive-grade discrete semiconductors: temperature cycling, high-temperature reverse bias, and ESD robustness.
The bidirectional configuration means a single device protects both polarities on the same line — no need for two unidirectional parts in anti-series. The tape-and-reel packaging suits automated pick-and-place assembly for volume production.
