D44H8 60V PNP TO220 Transistor Data
Key transistor data for the D44H8 transistor including key electrical parameters, pinout, package type and many other key transistor datasheet details.
The D45H8 is a PNP power transistor packaged in a TO220 package and it has a dissipation of 50W although some specifications may rate it a little higher at 70 W depending upn the manufacturer, etc.
The PNP D45H8 is the complement for the NPN D44H8 transistor and together thay are able to provide a complementary output pair for efficient power output stages.

| fT Min | Minimum cutoff frequency at which the current gain in a common emitter circuit falls to unity. |
| COB Max | Maximum collector capacitane, normally measured with emitter open circuit. |
| hFE | DC current gain for HFE at IC. [Note hfe is the small signal gain and although this may be slightly different, the transistor current gain will vary considerably from ne transistor to the next of the same type.] |
