Michael Wenzel effectively selected schottky diodes to prevent latch-up and provided direction to suppliers to develop more compact transient protection devices. He led the introduction of new transistor suppliers when load driver designs changed and conveyed expectations to thermistor suppliers for wider temperature performance. Wenzel maintained strong ties with over 150 electronic component suppliers and local representative firms and addressed any process change or end of life notifications to ensure a smooth transition. He supported having two qualified suppliers for over 600 part numbers and swiftly qualified replacement parts to prevent single sourcing situations. Additionally, Wenzel introduced ROHS compliance to suppliers in 2004 and qualified over 2000 ROHS compliant parts to transition from legacy to compliant components.
