Product details

Automotive-grade transient suppression for 128V rails

The 1.5SMC150CAHR7G: It clamps transients at 207V max while standing off 128V continuously, making it a fit for protecting 128V DC bus lines in automotive electronics. AEC-Q101 qualification confirms it meets the stress and reliability tests required for under-hood and chassis-mounted modules — the -55°C to 150°C operating junction range covers the full automotive temperature envelope with margin.

The bidirectional design means a single device protects both polarities — no need to orient the diode on the PCB, which simplifies placement and reduces BOM line items.

Frequently asked questions

What is the peak pulse power rating of 1.5SMC150CAHR7G?

It is rated for 1500W (1.5kW) peak pulse power under a 10/1000µs waveform. The clamping voltage at that peak current is 207V max, with a peak pulse current of 7.6A.
