1500 W peak pulse in a DO-201AE axial package
The 1.5KE550A-TP is a 1500 W (1.5 kW) peak pulse power Zener TVS diode from Micro Commercial Co, designed to clamp fast overvoltage transients on high-voltage rails up to 467 V reverse standoff.
Automotive temperature range and qualification
The Automotive grade designation means the device is manufactured and tested to the reliability and temperature-stress requirements typical of AEC-Q101-level discrete components — a meaningful signal for design-in reviews where the bill of materials must carry an automotive pedigree. The DO-201AE axial-lead package is a through-hole form factor suited for high-reliability soldering in power supplies, telecom line cards, and industrial control boards where the board-level thermal cycling and surge current demand a robust mechanical connection.
