Product Overview
The TIP42C is the 100 V grade of the TIP42 PNP power series, the heaviest of the TIP parts at 6.0 A continuous and 65 W (onsemi's published TIP42C data).
6 are on the shelf, sold each. The representative unit photographed reads TIP42C on the black face, with the Motorola batwing and 605 stamped under it and a small circular factory stamp lettered MEXICO around its rim sitting above the part number. 605 is left as it was found: the published data behind this page carries no decode for these stamped codes, so it is a marking string here and not a date. The tab is bare and flat with the mounting hole clear, the back of the tab photographs a dull red-brown, and the three leads are full length, straight and bright, with a fleck of pale residue at one lead root.
Key Features
- Polarity: PNP silicon power transistor
- VCEO: -100 V, the C voltage grade (per onsemi's published TIP42C data)
- IC: -6.0 A continuous (per onsemi)
- PD: 65 W at TC = 25 degC (per onsemi)
- hFE: 30 minimum (per onsemi)
- fT: 3 MHz (per onsemi)
- Package: TO-220AB plastic, three leads, metal tab with mounting hole; through-hole mount
- Series: TIP41/TIP42 is the published complementary pair, so the grade-matched NPN counterpart to this part is a TIP41C, which is not in this listing (per onsemi)
- Body marking on the unit photographed: MEXICO stamp, TIP42C, Motorola batwing, 605
- No pin assignment or tab connection is quoted here, because the data we work from does not publish one for this package; check onsemi's published TIP42C data against your board before mounting
- Verify against onsemi's published TIP42C data before designing in.
Applications
- PNP output device in a complementary audio amplifier
- Higher-current series pass element in a linear supply
- Motor and solenoid drive above the reach of a 3 A part
- Repair of legacy boards built around the TIP41/TIP42 pair
Frequently Asked Questions
How many should I order?
Order the count the build needs. 6 is the count on the shelf, sold one at a time, so if you want a matched set and a spare, take them on one order. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
Can I put a TIP32C in this socket instead?
Only if the socket never asked for the current. Both parts are PNP TO-220 devices at the same C grade of 100 V VCEO, and there the similarity stops: onsemi's published data gives the TIP42C 6.0 A continuous and 65 W, and the TIP32C 3.0 A continuous and 40 W. Going down that step halves the current headroom and takes a third off the dissipation, which is the difference between a stage that idles warm and one that does not survive the first fault. Going the other way, a TIP42C in a TIP32C position is the bigger device and its 3 MHz fT and 30 minimum hFE are worth checking against the drive your circuit provides. We ship the transistor by itself, with no heatsink, insulator or mounting hardware.
Six amps and sixty-five watts out of a package the size of a postage stamp, with the mounting hole still bright.
