Product details
Overview
TIP41C from onsemi is an NPN silicon power transistor in TO-220AB package, rated for 100 VCEO, 6 A continuous collector current, and 65 W total power dissipation at TC = 25°C. It serves as a general-purpose amplifier and switching device in linear power supplies, motor drivers, and relay interface circuits.
For engineers reviewing the TIP41C datasheet, pinout, applications, or equivalent options, key selection criteria include its 100 V blocking capability, 6 A DC current rating, thermal resistance of 1.67°C/W (junction-to-case), unclamped inductive energy handling (62.5 mJ), and Pb-free TO-220 packaging suitable for industrial-grade soldering processes.
Technical Context
The TIP41C operates as a bipolar junction transistor with fixed NPN polarity, requiring base current drive to control collector current flow. Its safe operating area (SOA) is defined up to 100 V and 6 A under pulsed conditions, with secondary breakdown limits validated at TJ = 150°C.
It features a minimum DC current gain (hFE) of 15 at IC = 3.0 A and VCE = 4.0 V, saturation voltage ≤1.5 V at IC = 6.0 A / IB = 600 mA, and fT ≥3.0 MHz - confirming suitability for low-to-moderate frequency switching and analog amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 Vdc - maximum collector-emitter voltage before breakdown; enables use in 80–100 V DC bus applications. |
| IC (continuous) | 6.0 Adc - sustained collector current capacity; supports medium-power load switching without forced cooling. |
| PD @ TC = 25°C | 65 W - thermal design must maintain case temperature ≤25°C to sustain full power; derates 0.52 W/°C above. |
| RJC | 1.67 °C/W - junction-to-case thermal resistance; requires heatsink interface with ≤1.67°C/W thermal path to maintain reliability. |
| hFE (min) | 15 @ IC = 3.0 A - ensures sufficient current gain for base drive efficiency in switching configurations. |
| VCE(sat) | ≤1.5 V @ IC = 6.0 A / IB = 600 mA - defines conduction loss ceiling; yields ≤9 W resistive dissipation at full load. |
| fT | ≥3.0 MHz - usable for audio-frequency amplification and PWM switching up to ~100 kHz with margin. |
Pinout & Package
Package: TO-220AB (Case 221A), plastic-encapsulated, through-hole mounting, with electrically isolated tab (collector-connected). Mounting hole accommodates M3 screw; tab must be insulated if not used as heat sink ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitting terminal for majority carriers | Low-impedance return path; connects to system ground or load return in common-emitter configuration. |
| 2 (Base) | Control electrode for carrier injection | Receives current-limited drive signal; requires series resistor to limit IB ≤2.0 A peak per datasheet. |
| 3 (Collector) | Current collection terminal | Connected to high-side load or power rail; tab is internally bonded to this pin - electrically active and thermally critical. |
Key Features
| Feature | Design Value |
|---|---|
| 100 V VCEO rating | Supports operation across 48 V, 72 V, and 96 V industrial DC systems without cascading devices. |
| 62.5 mJ unclamped inductive energy | Enables robust relay and solenoid driving without external snubbers under specified test conditions (L = 20 mH, 10 Hz). |
| UL 94 V-0 epoxy encapsulation | Meets flammability safety requirements for enclosed industrial equipment and power supplies. |
| Pb-Free TO-220 package option (TIP41CG) | Complies with RoHS Directive 2011/65/EU; compatible with standard lead-free reflow and wave soldering profiles. |
| ESD robustness (HBM >8 kV) | Reduces handling sensitivity during manual assembly and board-level testing; lowers risk of latent field failures. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJE13009 | Higher VCEO (400 V), lower IC (12 A), TO-220 package; fT ≈ 4 MHz, RJC = 1.5°C/W. | Better suited for flyback SMPS primary switches; less optimal for linear regulation due to higher VCE(sat). | Select when higher voltage isolation or switching efficiency is prioritized over linear-mode thermal performance. |
| BD249C | Lower VCEO (80 V), same IC (6 A), TO-126 package; hFE min = 40, RJA = 80°C/W (no heatsink). | Limited to ≤60 V systems; unsuitable for high-power dissipation without large heatsink. | Choose only for space-constrained PCBs where 80 V max and moderate thermal budget are acceptable. |
Compared with MJE13009 and BD249C, the TIP41C offers balanced 100 V/6 A capability with superior thermal resistance (RJC = 1.67°C/W) and proven reliability in linear and switching roles - making it preferred for industrial power stages where voltage margin and heatsink efficiency are jointly critical.

FAQ
What is the maximum collector-emitter voltage rating for the TIP41C?
The TIP41C has a maximum collector-emitter sustaining voltage (VCEO(sus)) of 100 Vdc at IC = 30 mA and IB = 0. This rating is confirmed in the Electrical Characteristics table and defines the absolute upper limit for DC or peak pulse voltage across the collector and emitter terminals. Exceeding this value risks avalanche breakdown and permanent damage to the TIP41C.
Can the TIP41C be used in a linear regulator configuration?
Yes, the TIP41C is explicitly designed for general-purpose amplifier and switching applications, including linear power supply regulation. Its 65 W power dissipation at TC = 25°C, low saturation voltage (≤1.5 V), and stable hFE across current range make it suitable as a pass transistor in adjustable regulators delivering up to 5 A. Thermal design must ensure case temperature remains within derating limits to avoid exceeding junction temperature.
Is the TIP41C pin-compatible with other TIP41 variants like TIP41A or TIP41B?
No - while all TIP41x variants share identical TO-220AB package and pinout (Emitter-Base-Collector), they differ in voltage ratings: TIP41A = 60 V, TIP41B = 80 V, TIP41C = 100 V. Substituting TIP41C for TIP41A in a 60 V circuit is electrically safe but may incur unnecessary cost and thermal overhead; substituting a lower-voltage variant for TIP41C risks catastrophic failure under 100 V stress. Always match the exact voltage requirement to the variant.
Does the TIP41C have a Pb-free packaging option?
Yes, the Pb-free version is designated TIP41CG and is documented in the Ordering Information table. It uses the same TO-220AB mechanical form factor and electrical specifications as the standard TIP41C, with lead-free terminations compliant with RoHS Directive 2011/65/EU. The "G" suffix indicates compliance, and both versions share identical thermal and electrical performance data.
What is the thermal resistance from junction to case (RJC) for the TIP41C?
The TIP41C has a maximum thermal resistance of 1.67°C/W from junction to case (RJC), as specified in the Thermal Characteristics table. This value assumes proper mounting with thermal compound and mechanical pressure on the collector tab. It enables accurate calculation of junction temperature rise (ΔTJ = PD × RJC) when designing heatsinks for the TIP41C in high-power applications.
