Product details
Overview
TIP147FTU from ON Semiconductor is a PNP epitaxial Darlington transistor in TO-3PF package, rated for -100 V VCEO, -10 A DC collector current, and 60 W power dissipation at TC=25°C. It delivers hFE ≥ 500 at -10 A, VCE= -4 V, with VCE(sat) = -3 V at -10 A/-40 mA drive, suited for high-current linear and switching applications including industrial motor control and power supply regulation.
For engineers reviewing the TIP147FTU datasheet, pinout, applications, or equivalent options, key selection criteria include its -100 V breakdown rating, built-in base-emitter shunt resistors (8 kΩ/0.12 kΩ), monolithic Darlington construction, thermal derating behavior above 25°C, and complementary pairing with TIP142F series devices.
Technical Context
The TIP147FTU integrates two PNP transistors in monolithic Darlington configuration with on-chip base-emitter shunt resistors (R1 ≈ 8 kΩ, R2 ≈ 0.12 kΩ) to ensure reliable turn-off and reduce external bias complexity. Its safe operating area (SOA) is defined up to 100 V and 10 A with pulse capability to -15 A.
It operates with VBE(sat) = -3.5 V at -10 A/-40 mA, exhibits tSTG = 2.5 µs and tf = 2.5 µs under specified test conditions (VCC = -30 V, RL = 6 Ω), and maintains junction temperature limits of -65°C to +150°C with storage and operating ranges fully aligned to industrial requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -100 V - Maximum continuous collector-emitter voltage before avalanche; defines upper rail limit in high-voltage PNP switch designs. |
| IC (DC) | -10 A - Sustained collector current capacity; enables direct drive of solenoids, relays, and medium-power loads without heatsink oversizing at moderate duty cycles. |
| PC @ TC=25°C | 60 W - Thermal power limit at case temperature 25°C; requires active heatsinking for sustained operation above ~50% duty cycle. |
| hFE | ≥500 @ VCE=-4 V, IC=-10 A - High current gain reduces required base drive current, easing interface with low-power controllers or logic outputs. |
| VCE(sat) | -3 V @ IC=-10 A, IB=-40 mA - Saturation voltage directly impacts conduction loss and heat generation in switching applications. |
| VBE(sat) | -3.5 V @ IC=-10 A, IB=-40 mA - Base-emitter voltage under full drive determines minimum driver compliance voltage needed. |
| tSTG/tf | 2.5 µs / 2.5 µs - Storage and fall times constrain maximum usable switching frequency in PWM or linear amplifier configurations. |
Pinout & Package
Package: TO-3PF - Metal can package with insulated flange, 3-pin layout (Base, Collector, Emitter), designed for high-power mounting with thermal interface to heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Control input terminal | Receives base current to enable conduction; internal 8 kΩ resistor to emitter ensures turn-off when drive is removed. |
| 2 (Collector) | High-side current sink node | Connected to positive supply rail in high-side switch topology; carries full load current and must be thermally coupled to heatsink. |
| 3 (Emitter) | Output reference terminal | Typically tied to system ground or load return; internal 0.12 kΩ shunt resistor provides emitter-base discharge path. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic Darlington structure | Single-die integration eliminates interconnect parasitics and mismatch, ensuring consistent gain and thermal tracking between driver and output stages. |
| Built-in base-emitter shunt resistors | R1 ≈ 8 kΩ (base-to-emitter), R2 ≈ 0.12 kΩ (emitter-to-base); eliminate need for external turn-off resistors and improve switching reliability. |
| -100 V VCEO rating | Supports operation in 80 V nominal systems with margin for transients and ripple, enabling use in industrial 48–72 V DC bus applications. |
| Complementary to TIP142F series | Matches TIP140F/141F/142F NPN counterparts in package, pinout, and gain profile-simplifies design of push-pull or H-bridge output stages. |
Applications
| Industrial Motor Control | Linear Regulator Pass Element |
|---|---|
|

IC Role / Device Role / Timing Role: Saturated switch interfacing microcontroller GPIO to relay coil, handling inductive kickback via inherent SOA robustness. Use Value: VCEO(sus) = -100 V withstands >2× rated coil voltage flyback; tSTG/tf < 3 µs enables fast relay cycling without contact arcing. |
Use Scenario: Controlling primary-side current in resistance spot welding timers where precise 10–200 ms pulses at 5–10 A are required. IC Role / Device Role / Timing Role: High-current switch gating transformer primary winding; operated in linear or saturated mode depending on weld profile. Use Value: ICP = -15 A pulse rating supports short-duration weld bursts; TO-3PF package enables direct bolt-down to water-cooled heatsinks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP Darlington transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD127G | TO-220 package, -100 V VCEO, -8 A IC, no internal shunt resistors | Requires external base-emitter resistor for reliable turn-off; lower power dissipation (35 W) limits continuous current in high-duty-cycle use. | Preferred where PCB space constraints favor surface-mount or where discrete bias control is desired. |
| TIP147 | Same die and specs but TO-3 (non-insulated flange) package; no "T" suffix indicating lead-free/rohs-compliant finish | Lacks insulated flange; requires insulating washer for heatsink mounting, increasing thermal resistance by ~0.5°C/W. | Select TIP147FTU when electrical isolation between collector and heatsink is mandatory per safety or noise requirements. |
Compared with MJD127G and TIP147, the TIP147FTU offers guaranteed built-in turn-off resistors and an insulated TO-3PF flange-critical for high-reliability industrial switching where layout simplicity and thermal/safety compliance are prioritized over cost or footprint.

FAQ
What is the maximum continuous collector current for TIP147FTU?
The TIP147FTU supports a maximum continuous DC collector current of -10 A at case temperature TC = 25°C. Derating is required above this temperature per the published power derating curve-approximately 0.48 W/°C reduction beyond 25°C. At TC = 100°C, the usable IC drops to approximately -6.2 A. Always verify thermal design using actual board layout and heatsink performance for the TIP147FTU.
Does TIP147FTU have built-in base-emitter resistors?
Yes, the TIP147FTU includes two monolithically integrated resistors: R1 ≈ 8 kΩ between base and emitter, and R2 ≈ 0.12 kΩ between emitter and base. These resistors ensure rapid turn-off and prevent unintended conduction due to leakage or noise, eliminating the need for external base-emitter pull-down components in most applications using the TIP147FTU.
What is the package type and mounting configuration for TIP147FTU?
The TIP147FTU uses the TO-3PF package-a metal-can, insulated-flange variant of TO-3 with three leads (Base, Collector, Emitter). The insulated flange allows direct mounting to a grounded heatsink without electrical isolation hardware. Pin 2 (Collector) is electrically connected to the case, making it ideal for high-side switch topologies where collector ties to the positive rail in the TIP147FTU.
How does TIP147FTU compare to TIP147 in terms of compliance and packaging?
The TIP147FTU is the RoHS-compliant, lead-free version of the legacy TIP147, with identical electrical specifications and TO-3PF packaging. The "T" suffix denotes tape-and-reel packaging and lead-free finish; the "U" indicates compliance with JEDEC standard J-STD-020 moisture sensitivity level 3. Both share the same die, but only the TIP147FTU meets modern environmental and assembly requirements for the TIP147FTU.
Can TIP147FTU be used as a direct replacement for TIP146FTU or TIP145FTU?
No-TIP147FTU is not a drop-in replacement for TIP146FTU (-80 V) or TIP145FTU (-60 V), despite identical pinout and package. Its -100 V VCEO and VCBO ratings reflect higher internal breakdown design, but substituting it into circuits rated for lower voltage may cause overdesign or unnecessary cost. Use TIP147FTU only where -100 V blocking is explicitly required; otherwise, TIP146FTU or TIP145FTU remain optimal for their respective voltage classes.
