Small 39.3 KB PDF covering the 2SC4562, with an unexplained _E suffix in the name, listed under schematics. Because 2SC is the JIS prefix for high-frequency NPN bipolar transistors, this is most likely a short datasheet. The name states no maker or package. Use it to identify the base, collector and emitter pins, read maximum ratings and gain data, and evaluate a substitute. Check the actual part marking against the document before relying on the pinout or ratings given.
