a-Ampere N-P-N Darlington Power Transistors
60-80-100 Volts, 60 Watts Gain of 500 at 0.5 A Gain of 1000 at 3 A
Features:
Applications:
- Operates from IC without predriver
- Power switching - Audio amplifiers
• Low leakage at high temperature
• Hammer drivers
- High reve... second-breakdown capability • Series and shunt regulators
The RCA120, RCA121, and RCA122 are monolithic n-p-n silicon Darlington transistors designed for low- and mediumfrequency power applications. The double epitaxial construction of these devices provides good forward and reverse second-breakdown capability; their high gain makes it possible for them to be driven directly from integrated circuits.
These devices are supplied in theJEDEC TO-220AB straightlead vers.
