Active production — 1500W unidirectional TVS in DO-214AB
The 1.5SMC16A TR13 PBFREE: Rated for 13.6 V reverse standoff, 15.2 V minimum breakdown, and 22.5 V clamping at 67 A peak pulse current (10/1000 µs waveform). The single unidirectional channel handles one polarity of transient — typical for clamping a DC rail or signal line to ground.
What the ratings mean for the BOM
The 1500 W peak pulse rating at 10/1000 µs means the diode absorbs a 1 ms half-sine surge of that energy without failing. For shorter transients (e.g. 8/20 µs), the peak power capability is higher — the 67 A figure at the 10/1000 µs waveform is the conservative limit for comparing parts across datasheets. Operating temperature spans -65°C to 150°C junction, covering cold-start automotive and high-temp industrial enclosures.
Sourcing and compliance
The TR13 suffix indicates 13-inch reel packaging; the PBFREE designation confirms RoHS compliance without added lead.
