TIP42C is STMicroelectronics’ 100 V PNP power transistor in TO-220 — 6 A continuous, 65 W with a heatsink — the exact PNP complement to the TIP41C, for push-pull audio output stages, H-bridge high sides, and PNP series regulators. The ‘C’ suffix is the 100 V grade (TIP42 40 V / A 60 V / B 80 V / C 100 V): same current and package across grades, so match the grade to your rail voltage. Selection advice: pair with TIP41C (same 100 V / 6 A / TO-220, in this catalog) for complementary designs — but keep both halves in the same manufacturer family, since hFE spreads (15–75) differ between vendors and unmatched pairs distort. The 65 W rating needs a real heatsink; a bare TO-220 in still air is good for roughly 2 W. VCE(sat) reaches 1.5 V at 6 A, so budget the conduction loss in efficiency-sensitive designs. Active, stocked in tube packing. Parameters trace to the manufacturer datasheet; state quantity, packing and date-code requirements in your RFQ — we reconfirm the offered lot before quotation and reply within 24 hours.
TIP42C is an STMicroelectronics PNP silicon power transistor in TO-220 — 100 V VCEO/VCBO, 6 A continuous collector current (10 A peak), 65 W power dissipation at 25 °C case temperature, VCE(sat) 1.5 V maximum at 6 A, hFE 30 minimum, 3 MHz transition frequency, -65 °C to +150 °C junction. The complementary NPN is TIP41C for push-pull output stages.
Against TIP32C: same 100 V rating and TO-220 package, but 6 A / 65 W versus 3 A / 40 W — the TIP42C is the higher-current upgrade, not a voltage or pinout change. Select it for audio output stages and switching service where 3 A is insufficient; verify the hFE rank if your design depends on minimum gain.

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
The suffixes in TIP42C are not decoration — each one pins down the orderable configuration: TO-220 package plus the grade and packing the code was qualified for. Treat any code that differs by a single suffix character as a different device and quote the full code exactly as printed on your BOM.
The package (TO-220) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.
Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.
Add TIP42C to your RFQ with the complete ordering code, the manufacturer (STMicroelectronics), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
