Additional Details:

The 2SA562-O features a collector-base voltage (VCBO) rating of -30V, a collector-emitter voltage (VCEO) rating of -25V, and an emitter-base voltage (VEBO) rating of -5V. The collector current (IC) is rated at -50mA, and the collector power dissipation (PC) is 200mW. The operating junction temperature (Tj) is 150°C. The transistor is typically supplied in a small signal package, such as a TO-92 or similar through-hole package. The "O" in the part number likely refers to a specific gain rank, with different ranks offering slightly varying hFE values. Careful attention to the datasheet is recommended for optimal circuit design.

This transistor is known for its relatively high hFE and low noise figure, which makes it valuable for amplifying weak signals. Its compact size also allows for use in miniaturized electronic devices.
