For BOM positions still requiring this exact order code, procurement must rely on independent distribution and broker channels.
AEC-Q101 qualification — what it means for replacement
This part carries Automotive, AEC-Q101 qualification, which means it was tested to the stress and reliability requirements for automotive-grade semiconductors — temperature cycling, high-temperature reverse bias, and surge endurance at -65°C to 150°C junction. Any pin-compatible replacement considered for a production line must also be AEC-Q101 certified to avoid a PPAP deviation. The bidirectional channel protects a single signal or power rail; the 185 pF capacitance at 1 MHz is typical for a 600 W TVS in this voltage class and will not load a 1 MHz bus, but should be checked for higher-frequency interfaces.
Parametric baseline for cross-shopping
The 47.8 V reverse standoff and 53.2 V minimum breakdown set the DC operating ceiling: the protected rail must stay below 47.8 V continuous. Clamping at 77 V at the 7.8 A peak pulse current defines the voltage the downstream circuit must survive during a surge. Package is DO-214AA (SMB), surface-mount, supplied on Tape & Reel.
