2N5002 Temperature-Power Derating Curve
2N5002 Temperature Derating Curve

The chart indicates the maximum power dissipation with increasing case temperature. Maximum operational power dissipation is achievable at 25C. However above 25C the maximum package dissipation, or power, must be reduce to insure that the devices junction temperature remains constant. The higher the ambient temperature is increased the lower the allowable power dissipation, as depicted in the curves.
Derating is the method of decreasing a devices operational limits as temperature is increased, in this case derating a devices operational power dissipation vs increasing case temperature. This particular graph depicts the derating of a 2N5002 transistor in a TO-59 metal package. Transistor Derating Curves.

Refer to MIL-PRF-19500/534; Semiconductor Device, Transistor, NPN, Silicon, Power, Types 2N5002 and 2N5004, [TO-59]

Inactive for new designs, use MIL-PRF-19500/613, A 2N7373 in a TO-254 package.
MIL-PRF-19500/613 is a TO-254 package version of MIL-PRF-19500/534, which is a TO-210 (TO-59) package version. The military 2N7373 contains the same die as the military 2N5004. The MIL-PRF-19500/613 is preferred over the MIL-PRF-19500/534 whenever interchangeability is not a problem. For new design use 2N7373. The 2N5004 is inactive for new designs [for the government or military designs].

2N5002 Maximum Operation Ratings:
Collector Emitter Voltage = 80 volts dc
Emitter Base Voltage = 5.5 volts dc
Power Dissipation 250C = 58 Watts
Operating Temperature = -65 to +2000C
Storage Temperature = -65 to +2000C
Refer to the 2N5002 data sheet for additional data

Design Note; This device requires wires to attach to the three terminals. Use the largest and shortest wires possible. Heavy gauge wires insure low resistance and voltage drop across the wires, and short wires insure good heat transfer and low inductance.
