1.5 kW peak pulse — the protection envelope for a 7 V rail
The SMCJ7.0A-13-F: Its 7.78 V minimum breakdown voltage triggers before the protected circuitry sees damaging overvoltage, and the 12 V maximum clamping voltage at 125 A peak pulse current (10/1000 µs waveform) limits the let-through energy to a level most downstream components survive. This is a general-purpose transient suppressor — the 'No' on power line protection means it is best suited for signal lines, low-voltage DC power inputs, or I/O ports rather than mains or high-energy bus clamping.
DO-214AB SMC — footprint and thermal path
Housed in the DO-214AB (SMC) package, the device sits on a surface-mount pad that conducts heat into the PCB copper plane. The wide -55°C to 150°C junction temperature range means it operates reliably in outdoor telecom enclosures, industrial control cabinets, or under-hood automotive environments without derating concerns at the high end. Supplied in Tape & Reel (TR) with a Cut Tape (CT) option, the SMCJ7.0A-13-F flows through standard pick-and-place lines. The single unidirectional channel handles one polarity — for AC or bidirectional protection, pair two devices back-to-back or select a bidirectional variant from the SMCJ family.
Active production — sourcing posture
The base product number SMCJ7.0 covers the full voltage range; the -13-F suffix denotes the tape-and-reel packaging variant.
