Product details

Automotive-grade 30V TVS in DO-214AC

The SMAJ30AQ-13-F: It is designed to clamp transients on 30V nominal rails in automotive and industrial environments. The 33.3V minimum breakdown voltage ensures the TVS triggers before the protected circuit's voltage tolerance is exceeded.

AEC-Q101 qualification and operating range

The -55°C to +150°C junction temperature range covers under-hood and cabin electronics without derating. The unidirectional channel (single TVS) is suited for DC rails where polarity is fixed.

Supplied in DO-214AC (SMA) package, surface mount. The SMA footprint is common and matches standard solder reflow profiles. Available in Tape & Reel (TR) or Cut Tape (CT) options for volume or prototype quantities. The base product number SMAJ30 covers multiple variants; the 'AQ' suffix denotes the automotive AEC-Q101 grade, and '-13-F' indicates the reel packaging. Ensure the BOM specifies this exact ordering code for the automotive temperature and reliability grade.
