Product details

TVS diode for 12.8 V rails — what the ratings mean

The 1.5SMC15C: The 1500 W rating is the peak pulse power dissipation at 25 °C — derate for elevated ambient temperature per the manufacturer's curve. The bidirectional configuration means a single device protects both positive and negative transients on the same line, saving board space versus two unidirectional diodes in anti-series. The DO-214AB (SMC) surface-mount package supports standard reflow soldering and is compatible with automated pick-and-place assembly.

Obsolete — sourcing through independent channels

Littelfuse has designated the 1.5SMC15C as obsolete.

Frequently asked questions

What is the closest pin-compatible alternative to the 1.5SMC15C?

The DO-214AB footprint is shared with many SMCJ-series TVS diodes, but electrical parameters (standoff, breakdown, clamping) must be matched to the application.
