Note that some surplus listings describe the 1700C as a germanium device — federal supply data lists it as silicon. No manufacturer datasheet is publicly available for this part, so verify pinout, gain and saturation characteristics electrically before designing it into a circuit. As with other TO-3 power devices, the collector is connected to the case, so the package must be insulated from a grounded heatsink where the circuit requires it.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQ\u0026amp;A\u003c\/strong\u003e\u003cbr\u003eQ: Is the TRW 1700C silicon or germanium? A: Silicon. Federal supply data for NSN 5961-00-772-8144 lists the device as silicon, although some surplus listings incorrectly describe it as germanium.\u003cbr\u003eQ: What are the alternate part numbers?
