AWSS5H60: A 5 A, 60 V Schottky for Automotive Lighting and ECU Power

AWSS5H60 appears in the Good-Ark new-release table as a 5 A, 60 V Schottky rectifier in eSGC (TO-277). Its useful starting point is a load whose forward-current and reverse-voltage requirements can fit the smaller family classes. This review separates the current budget from the package label.

Build the current budget from the conduction interval

Identify whether the diode carries the full load current or conducts during only one interval of a switching or protection cycle. List average, RMS and peak currents separately. A load that averages a modest current can still impose high charging pulses; the average alone cannot establish surge capability.

For an intentionally simplified rectangular waveform of 4 A during 25% of the period and zero otherwise, the diode average current is 1 A and its RMS current is 2 A. These calculated values describe the assumed waveform, not an AWSS5H60 operating approval. The exact datasheet must supply the applicable current and thermal limits.

Decide whether the 60 V class fits

Measure or calculate the largest reverse voltage at the diode terminals under the relevant normal and fault conditions. Include startup and switching overshoot where they apply. A nominal vehicle rail voltage does not establish the worst reverse stress.

If the reverse-voltage requirement cannot fit the 60 V class, compare AWSS5H100 through its own documentation. If current is the limiting factor while the voltage requirement fits, compare AWSS10H60 instead. These are different selection changes and need different evidence.

Turn the shortlist into a board-level decision

At the intended current and temperature, obtain forward-drop and reverse-leakage data. Use the actual pad, copper and enclosure in the temperature assessment. The eSGC name does not provide a universal thermal resistance or allow the 5 A label to be used without its test conditions.

The AWSS family guide owns the four-part matrix; keep this page with the load-current calculation and the evidence for the 60 V decision.

Obtain the exact model documents

Use the AWSS5H60 product page to locate the manufacturer entry. Obtain the current datasheet revision and resolve any missing operating, thermal, surge or qualification limit before approving the part.
