Additional Details:

The 2N5305 typically has a collector-emitter voltage (VCEO) rating of 80V and a collector current (IC) rating of 8A. The power dissipation (PD) is typically around 50W. The current gain (hFE) is typically between 20 and 70. It is commonly packaged in a TO-3 package. The operating temperature range is usually between -65°C to +200°C. This is a through-hole component and requires appropriate heat sinking when operated at high power levels. The saturation voltage VCE(sat) is typically around 1V at the rated collector current and base current.
