Product Overview
Motorola 2N5190, a JEDEC-registered NPN bipolar power transistor in a flat plastic case. It pairs a 4 A collector current rating with 40 W of dissipation and a 40 V rating, and the screw hole through the body lets it bolt flat to a heat sink.
Key Features
- Part number: 2N5190, Motorola marking
- Type: NPN bipolar junction transistor
- Collector current: 4 A
- Voltage rating: 40 V
- Power dissipation: 40 W
- Transition frequency: 2 MHz
- Package: TO-126 / TO-225, three in-line through-hole leads, mounting hole through the body
Applications
- Swapping out a failed 2N5190 on an older board where the number is printed on the parts list or the silkscreen
- Series-pass element in a small linear supply on the bench, screwed to a heat sink
- Driving relays, lamps, solenoids or small DC motors
Frequently Asked Questions
Is this a TO-126 or a TO-225 transistor?
Both. The 2N5190 is catalogued under each name for the same flat plastic case, so a parts list that calls for either one is asking for this body.
Motorola put a screw hole through this slab of plastic, and not so it could hang on a pegboard. Bolt it down first, then solder the leads.
