Additional Details

The 2SC4691 is typically packaged in a TO-220 or similar through-hole package. Its high breakdown voltage (VCEO) allows it to operate reliably in high-voltage circuits. The high collector current (IC) capability enables the device to drive inductive loads, such as motors and transformers. The low saturation voltage (VCE(sat)) minimizes power dissipation when the transistor is in the ON state, improving overall circuit efficiency. The fast switching speed allows for efficient operation in high-frequency switching power supplies. The device has a relatively high power dissipation capability. Proper heatsinking is often required to maintain the junction temperature within the allowable range. The transistor is designed for linear mode, as well as pulse applications.
