Product details

AEC-Q101 Zener TVS for 60V rails

The 1.5SMBJ60A-H: Its 60V reverse standoff voltage (66.7V min breakdown) and 96.8V clamping clamp 15.5A transients, making it a fit for protecting 48V and 60V nominal rails in automotive and industrial power buses.

AEC-Q101 qualification certifies this part for automotive stress grades — the -55°C to 150°C junction temperature range covers under-hood and engine-bay thermal profiles. The DO-214AA (SMB) package is a standard surface-mount footprint for power TVS diodes, compatible with reflow soldering profiles used in automotive ECU assembly.

Frequently asked questions

What is the clamping performance of the 1.5SMBJ60A-H at its peak pulse current?

At 15.5A peak pulse current (10/1000µs waveform), the 1.5SMBJ60A-H clamps at 96.8V maximum. The 60V reverse standoff means it stays off the line under normal 48V or 60V bus conditions, only conducting when a transient exceeds the 66.7V minimum breakdown threshold.

Which automotive-grade qualification does the 1.5SMBJ60A-H carry?

It is AEC-Q101 qualified, covering the semiconductor device stress tests and reliability requirements for automotive-grade components. The -55°C to 150°C junction temperature range supports deployment in under-hood and powertrain environments.
