NTE273 PNP Silicon Darlington Complementary Power Amplifier

Formerly: ECG273

(PNP) Silicon Darlington Complementary Power Amplifiers

See also >>> NTE272 (NPN)

Description:
The NTE272 (NPN) and NTE273 (PNP) are silicon complementary Power Amplifiers in a TO202 type case designed for use in complementary amplifiers and driver applications.

Features:
- High DC Current Gain:
hFE = 25,000 (Min) @ IC = 200mA
= 15,000 (Min) @ IC = 500mA
- Collector−Emitter Breakdown Voltage: V(BR)CES = 40V @ IC = 500mA
- Low Collector−Emitter Saturation Voltage: VCE(sat) = 1.5V @ IC = 1A
- Monolithic Construction for High Reliability

Note 1. NTE273 is a discontinued device and no longer available.
Note 2. Due to the monolithic construction of this device, breakdown voltages of both transistor elements are identical. V(BR)CES is tested in lieu of V(BR)CEO in order to avoid errors caused by noise pickup. The voltage measured during the V(BR)CES test is the V(BR)CEO of the output transistor.
Note 3. Pulse test: Pulse Width ≤ 300μs, Duty Cycle ≤ 2.0%.

Uniwatt darlington transistors can be used in any number of low power applications, such as relay drivers, motor control and as general purpose amplifiers. As an audio amplifier these devices, when used as a complementary pair, can drive 3.5 watts into a 3.2ohm speaker using a 14 volt supply with less than one per cent distortion. Because of the high gain the base drive requirement is as low as 1mA in this application. They are also useful as power drivers for high current application such as voltage regulators.
