NTE87 (NPN) & NTE88 (PNP)
Silicon Complementary Transistors
High Power Audio, Disk Head Positioner
for Linear Applications
Description:
The NTE87 (NPN) and NTE88 (PNP) are complementary silicon power transistors in a TO3 type
package designed for high power audio, disk head positioners, and other linear applications. These
devices can also be used in power switching circuits such as relay or solenoid drivers, DC–to–DC
converters or inverters.
Features:
D High Safe Operating Area: 1.2A @ 100V
D Completely Characterized for Linear Operation
D High DC Current Gain: hFE = 20 Min @ IC = 2A
D Low Saturation Voltage: 2V
D For Low Distortion Complementry Designs
