D44H8 / NZT44H8 Discrete POWER & Signal Technologies D44H8 NZT44H8 C B E C E C TO-220 SOT-223 B NPN Power Amplifier This device is designed for power amplifier, regulator and switching circuits where speed is important. Sourced from Process 4Q. Absolute Maximum Ratings* Symbol VCEO IC TJ, Tstg Collector-Emitter Voltage Collector Current - Continuous TA = 25°C unless otherwise noted Parameter Value 60 8.0 -55 to +150 Units V A °C Operating and Storage Junction Temperature Range *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 degrees C. 2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
