Product Overview
The TIP29C is the 100 V grade of the TIP29 NPN power series, and at 1.0 A continuous and 30 W it is the lightest-duty part in the TIP group (onsemi's published TIP29C data).
20 are on the shelf, sold each. The representative unit photographed reads TIP29C across the black face with the Motorola batwing and 737 on the line below it, and a round factory stamp sits above the part number, too soft in these photos to read out. 737 is a string and stays one here: nothing in the published data we work from decodes these stamped codes, so we will not hand you a manufacture date we cannot source. The tab is bare with a clear mounting hole, the back of it photographs a dull red-brown, and the three leads are full length and unbent with a grey, lightly mottled finish rather than a bright mirror.
Key Features
- Polarity: NPN silicon power transistor
- VCEO: 100 V, the C voltage grade (per onsemi's published TIP29C data)
- IC: 1.0 A continuous (per onsemi)
- PD: 30 W at TC = 25 degC (per onsemi)
- Package: TO-220 plastic (TO-220AB), three leads, metal tab with mounting hole
- Mount: through-hole
- Series: TIP29/TIP30 is the published complementary pair, so this part's grade-matched PNP counterpart by number is a TIP30C (per onsemi)
- Body marking on the unit photographed: TIP29C, Motorola batwing, 737
- No pin assignment or tab connection is quoted here; the data we work from does not publish one for this package, so check onsemi's published TIP29C data against your board before mounting
- Verify against onsemi's published TIP29C data before designing in.
Applications
- Medium power linear and switching stages
- Driver transistor ahead of a larger output pair
- Lamp, relay and small solenoid switching
- Repair of legacy boards built around the TIP29 family
Frequently Asked Questions
How many should I order?
Order the count the build needs. 20 are here and they sell one at a time, which covers a repair and a drawer's worth of spares on the same order instead of two. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
The C says 100 volts, so can I use it where a TIP31C went?
The suffix reads the same and the current rating does not. Across TIP29/30, TIP31/32 and TIP41/42 the C suffix means 100 V VCEO, so on voltage this part stands with the rest. On current it does not: onsemi's published TIP29C data gives 1.0 A continuous and 30 W, while onsemi's published data gives the TIP31B 3.0 A and 40 W and the TIP42C 6.0 A and 65 W. A TIP29C dropped into a socket sized for a 3 A part will hold the voltage off and then run out of current, so size it by the amps and not by the letter. What ships is the transistor alone, with no heatsink, insulator or hardware.
A hundred volts standing behind a single amp: the TIP29C has always been the modest one at the family table.
