The -55°C to 150°C junction temperature range covers automotive under-hood and industrial enclosure environments; no derating needed at typical ambient temperatures up to 85°C. ## General-purpose class — no power-line rating Marked as General Purpose applications with no power line protection, this TVS is intended for signal and low-power rail transient suppression — not for sustained overvoltage clamping on mains or high-current DC buses. The bidirectional configuration means polarity is irrelevant during placement; the part clamps equally on positive and negative transients, simplifying layout on AC-coupled or bipolar signal lines.","metaTitle":"SMAJ30CA-13 Diodes Inc TVS, 30V Bidirectional, 400W","metaDescription":"SMAJ30CA-13 bidirectional TVS diode, 30V reverse standoff, 48.4V clamp, 400W peak pulse.
