Product Overview
Motorola's MJE1100 is an NPN silicon Darlington power transistor in the TO-127 plastic package, Motorola Case 90. The MJE1100 family of plastic medium-power complementary transistors was designed for the driver and output stages of complementary audio amplifiers.
Key Features
- Polarity: NPN Darlington, silicon
- Collector-emitter voltage (VCEO): 60 V
- Collector-base voltage (VCB): 60 V
- Collector current (IC): 5 A
- Power dissipation (PD): 70 W
- DC current gain (hFE): 750 minimum
- Package: TO-127 (Motorola Case 90), 3-lead through-hole plastic body with a round mounting hole
- Exposed metal heatsink pad on the back
Applications
- Replacing a failed driver or output Darlington in a vintage complementary audio amplifier built around the MJE1100.
- Switching relays, solenoids or lamps from a weak control signal, where 750 minimum gain lets a small base current handle amps.
- Pass element in a bench-built linear power supply, bolted to a heatsink through the body's mounting hole.
Frequently Asked Questions
What package is the MJE1100 in?
TO-127, which Motorola called Case 90: a flat plastic power body with three flat leads, a round mounting hole through the body and an exposed metal pad on the back.
Is the MJE1100 still in production?
No. Motorola's discrete line passed to ON Semiconductor, now onsemi, and the MJE1100 is no longer offered.
What is the PNP complement to the MJE1100?
The MJE1090 through MJE1093 are the PNP units of the same series. The MJE1090 matches this part at 60 V, 5 A and 750 minimum gain in the TO-127 package.
Two transistors share one plastic body here, so a trickle of base current moves real collector current. The MJE1100 is out of production, which makes an unused one the straightest path back to an amplifier's original parts list.
