1500W bidirectional TVS for 12V rail protection
The 1.5SMC15CA V7G: The single bidirectional channel handles positive and negative transients symmetrically, so you don't need to worry about orientation on the PCB — useful for AC-coupled telecom lines or unipolar rails where reverse polarity protection is already in place.
Housed in a DO-214AB (SMC) surface-mount package, the same footprint as standard SMC diodes. The 1500W rating demands a decent copper pad on the cathode tab side to sink the transient heat — a 12x12mm pad per JEDEC recommendations keeps the junction below 150°C during the surge. The base product number is 1.5SMC15; the V7G suffix indicates the reel and packing variant.
Sourcing and compliance
Typical compliance documentation includes RoHS and REACH declarations from the manufacturer; UL recognition and IEC 61000-4-5 surge testing apply to the 1.5SMC series. Confirm specific certs with the lot-specific documentation at time of order.
