TN6725A CB TO-226 E NPN Darlington Transistor This device is designed for applications requiring extremely high current gain at collector currents to 1A. Sourced from Process 05. See MPSA14 for characteristics. Absolute Maximum Ratings* Symbol TA = 25°C unless otherwise noted Parameter Value Units VCES Collector-Emitter Voltage 50 V VCBO Collector-Base Voltage 60 V VEBO Emitter-Base Voltage 12 V IC Collector Current - Continuous 1.2 A TJ, Tstg Operating and Storage Junction Temperature Range -55 to +150 °C *These ratings are limiting values above which the serviceability of any semiconductor device may be impaired. NOTES: 1) These ratings are based on a maximum junction temperature of 150°C. 2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
