Product details
Overview
TIP147TU from ON Semiconductor is a PNP silicon Darlington power transistor designed for high-current, low-frequency switching and linear amplifier applications. It delivers 10 A continuous collector current, sustains 100 Vdc collector-emitter voltage, and achieves minimum DC current gain (hFE) of 1000 at IC = 5 A and VCE = 4 V - enabling robust operation in motor control drivers and industrial power supplies.
For engineers reviewing the TIP147TU datasheet, pinout, applications, or equivalent options, key selection criteria include its 100 VCEO(sus) rating, monolithic construction with built-in base-emitter shunt resistor, thermal resistance of 1.0 °C/W (junction-to-case), and compatibility with TO-218 (Case 340D–02) heatsink mounting.
Technical Context
The TIP147TU integrates two PNP transistors in monolithic Darlington configuration with an internal base-emitter shunt resistor (~8.0 kΩ), reducing external bias complexity and improving turn-off speed. Its complementary NPN counterpart is TIP142, supporting push-pull designs.
It operates within –65°C to +150°C junction temperature range and features second-breakdown-limited safe operating area (SOA) up to 100 V × 10 A (dc), with thermal resistance RθJC = 1.0 °C/W ensuring efficient heat transfer to heatsinks when mounted per Case 340D–02 mechanical specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO(sus) | 100 Vdc minimum - supports unclamped inductive loads up to 100 V without secondary breakdown under specified test conditions. |
| IC (continuous) | 10 Adc - enables direct drive of medium-power solenoids, relays, and DC motor windings without external current boosting. |
| hFE (min) | 1000 @ IC = 5 A, VCE = 4 V - allows low-base-drive-current switching (e.g., <5 mA base current for 5 A load), simplifying driver stage design. |
| VCE(sat) | 2.0 V max @ IC = 5 A, IB = 10 mA - limits conduction loss to ≤10 W at 5 A, critical for thermal management in sealed enclosures. |
| RθJC | 1.0 °C/W - mandates use of mechanically secured heatsink (e.g., thermal paste + screw clamp) to maintain TJ ≤150°C at full 125 W dissipation. |
| Switching ts/tf | 2.5 µs max each - suitable for ≤20 kHz PWM switching in lamp dimmers and battery chargers, but not for high-frequency SMPS. |
Pinout & Package
Package: TO-218 variant (ON Semiconductor Case 340D–02), metal tab isolated, intended for bolt-down heatsink mounting with insulating washer. Dimensions: 20.35 mm × 18.20 mm × 16.20 mm (L×W×H), 4-pin single-in-line (SIL) layout with dual collector terminals for current sharing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Control input node | Accepts low-current drive (≤0.5 Adc continuous); internal ~8.0 kΩ shunt resistor ensures reliable turn-off without external pull-down. |
| 2 (Collector) | Main current sink path | Primary high-current output terminal; electrically tied to metal tab - must be insulated from heatsink unless common-collector topology is used. |
| 3 (Emitter) | Power return reference | Connected to system ground or negative rail; carries full load current and defines emitter-follower or common-emitter bias point. |
| 4 (Collector) | Redundant current sink path | Dual-collector construction lowers effective on-resistance and improves thermal distribution - both collectors must be paralleled externally. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic Darlington pair | Eliminates discrete interstage wiring, reduces parasitic inductance, and guarantees matched transistor characteristics for stable gain. |
| Built-in base-emitter shunt resistor | ~8.0 kΩ resistor ensures rapid charge removal from base region, cutting storage time (ts) to ≤2.5 µs without external components. |
| 100 VCEO(sus) rating | Enables direct interface with 90 VAC rectified rails or 72 VDC battery systems without snubber networks in resistive/inductive loads. |
| 125 W total dissipation @ TC = 25°C | Supports high-duty-cycle linear regulation (e.g., lab power supply pass element) when paired with ≥1.0 °C/W heatsink assembly. |
Applications
| Industrial Motor Control | Linear Power Supply Pass Element |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current PNP Darlington switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD127G | TO-252 (DPAK) surface-mount package; 80 VCEO, 8 A continuous, RθJC = 3.0 °C/W. | Limited to ≤60 W dissipation; requires PCB copper pour + forced air for equivalent thermal performance. | Select for space-constrained PCBs where heatsink mounting is impractical and voltage stress stays below 80 V. |
| BDW53C | TO-220 package; 100 VCEO, 12 A continuous, no integrated base shunt resistor. | Requires external 10 kΩ base-emitter resistor for reliable turn-off; higher base drive current needed. | Select when cost sensitivity outweighs board-space savings and driver IC can supply ≥20 mA base current. |
Compared with MJD127G and BDW53C, the TIP147TU uniquely combines 100 VCEO(sus), 10 A current capability, monolithic base-shunt integration, and TO-218 package optimized for bolt-down heatsinking - making it the preferred choice for ruggedized industrial switching where reliability and thermal margin are prioritized over footprint size.

FAQ
What is the maximum safe operating voltage for TIP147TU in inductive switching applications?
The TIP147TU has a minimum collector-emitter sustaining voltage VCEO(sus) of 100 Vdc at IC = 30 mA, validated under unclamped inductive load testing. For reliable operation, peak transient voltage must remain ≤100 V - requiring appropriate snubbers or clamping diodes if back-EMF exceeds this threshold. Always verify actual circuit waveforms with oscilloscope capture during prototype validation of the TIP147TU.
Does TIP147TU require an external base-emitter resistor for turn-off?
No - the TIP147TU incorporates a monolithic ~8.0 kΩ base-emitter shunt resistor, eliminating the need for external turn-off components. This internal resistor ensures rapid discharge of base charge, limiting storage time to ≤2.5 µs. External resistors may still be used for fine-tuning drive strength, but are not required for basic functionality of the TIP147TU.
Can TIP147TU be used in parallel with other TIP147TU devices to increase current capacity?
Yes - the TIP147TU's dual-collector (pins 2 and 4) and matched gain characteristics support current sharing when paralleled with identical units. Use individual base resistors (e.g., 10 Ω) and emitter ballast resistors (0.1 Ω) to ensure thermal and current balance. Derate total current by 15% per additional device to maintain safe junction temperature in the TIP147TU array.
What is the thermal resistance from junction to case (RθJC) for TIP147TU, and how does it affect heatsink selection?
The TIP147TU specifies RθJC = 1.0 °C/W, measured from die junction to the metal tab surface. To maintain TJ ≤150°C at full 125 W dissipation, the combined RθCS (case-to-sink) and RθSA (sink-to-ambient) must be ≤0.5 °C/W. This demands a high-performance heatsink (e.g., 0.25 °C/W) with thermal interface material and mechanical clamping - not adhesive tape or clip-on mounts - for the TIP147TU.
Is TIP147TU pin-compatible with TIP145 or TIP146?
No - while TIP145 (60 V) and TIP146 (80 V) share the same Case 340D–02 package and pinout (Base–Collector–Emitter–Collector), the TIP147TU is not a drop-in replacement due to its higher 100 V rating and distinct SOA curve. Substituting without verifying voltage margin, thermal derating, and switching behavior risks premature failure. Always validate circuit performance with the exact TIP147TU specification set.
