Product details

Automotive-grade transient suppression

The SMAJ70CAQ-13-F: The DO-214AC (SMA) package is a surface-mount footprint with a low profile — it reflows on standard lead-free profiles and the cathode band identifies the bidirectional orientation (both directions are identical, so the band is a reference mark, not a polarity indicator).

Active production, sourced per RFQ

For a BOM position that calls this exact order code, the fit is confirmed by the 70V reverse standoff and the AEC-Q101 automotive grade — any replacement would need to match the DO-214AC footprint, the bidirectional polarity, and the 400W peak pulse rating.
