Product details

Active production, AEC-Q101 qualified

The SMBJ20AQ-13-F: It is rated for the -55°C to +150°C junction temperature range common in under-hood and engine-bay electronics.

Clamping performance for 20V rails

With a 20V reverse standoff voltage, this Zener TVS protects 20V nominal supply rails.

DO-214AA SMB footprint and single-channel layout

The DO-214AA (SMB) package is a surface-mount footprint with a low profile — the solder pad pattern is standard and shared with many SMB-packaged TVS diodes, easing second-source qualification. Unidirectional single-channel configuration means one TVS per protected line; for bidirectional protection on AC or bipolar rails, two parts back-to-back are needed.
