Additional Details

The 2SB631K transistor is commonly used in low to medium power amplifier circuits. The hFE range specifies the DC current gain, which is the ratio of collector current to base current. A higher hFE allows the transistor to provide more current gain for a given input current. The transition frequency (fT) indicates the frequency at which the current gain drops to unity (1). The TO-92 package is a through-hole package, which makes it suitable for prototyping and breadboarding. The datasheet provides detailed electrical characteristics and thermal considerations for reliable operation of the device. Always consult the datasheet for specific design requirements and limitations.
