Product details
Overview
TIP147 from ON Semiconductor is a PNP Darlington silicon power transistor designed for low-frequency switching and general-purpose amplifier applications. It features a minimum collector-emitter sustaining voltage of 100 Vdc, continuous collector current rating of 10 A, total power dissipation of 125 W at TC = 25°C, DC current gain (hFE) ≥1000 at IC = 5.0 A and VCE = 4 V, and monolithic construction with built-in base-emitter shunt resistor. It is commonly used in high-current linear regulators and motor control circuits.
For engineers reviewing the TIP147 datasheet, pinout, applications, or equivalent options, key selection considerations include its 100 V VCEO(sus), 10 A IC continuous rating, 125 W PD capability, Darlington configuration enabling high current gain with minimal base drive, and TO-218 (SOT-93) package thermal performance with RJC = 1.0 °C/W.
Technical Context
The TIP147 operates as a PNP Darlington pair with integrated base-emitter shunt resistor, delivering high DC current gain while reducing external component count. Its safe operating area is defined by both thermal limits (125 W at TC = 25°C, derated above 25°C) and secondary breakdown constraints, especially under unclamped inductive loads up to 100 mJ.
Switching behavior is characterized by delay time ≤0.15 µs, rise time ≤0.55 µs, storage time ≤2.5 µs, and fall time ≤2.5 µs under specified resistive load conditions (VCC = 30 V, IC = 5.0 A, IB = 20 mA). Saturation performance includes VCE(sat) ≤2.0 V at IC = 5.0 A/IB = 10 mA and ≤3.0 V at IC = 10 A/IB = 40 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO(sus) | 100 Vdc minimum - supports operation in 80–100 V rail systems without breakdown |
| IC (Continuous) | 10 Adc - enables direct drive of high-power loads such as solenoids and relay coils |
| PD @ TC = 25°C | 125 W - requires heatsink mounting for sustained full-load operation |
| hFE | ≥1000 @ IC = 5.0 A, VCE = 4 V - reduces required base drive current to ~5 mA for 5 A output |
| RJC | 1.0 °C/W - allows efficient heat transfer from junction to heatsink in TO-218 package |
| VCE(sat) | ≤2.0 V @ IC = 5.0 A, IB = 10 mA - limits conduction loss to ≤10 W at 5 A |
| Switching ts/tf | ≤2.5 µs each - suitable for line-frequency (50/60 Hz) and audio-range switching, not RF |
Pinout & Package
Package: SOT-93 (TO-218), case 340D, metal tab with isolated collector terminals. Mounting requires insulating washer and torque-controlled screw for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Control input node | Accepts low-current drive signal; internal shunt resistor provides turn-off bias path |
| 2 (Collector) | Main current sink terminal | Electrically connected to metal tab; must be insulated from heatsink unless common-collector topology is used |
| 3 (Emitter) | High-current output reference | Serves as output return path; carries full load current and defines circuit ground reference in emitter-follower configurations |
| 4 (Collector) | Second collector connection | Dual-collector design improves current handling and thermal distribution; paralleled internally with Pin 2 |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP Darlington power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD127G | TO-252 (DPAK) surface-mount package; lower PD = 30 W; VCEO = 100 V; hFE ≥1000 @ IC = 2 A | Not suitable for >3 A continuous loads or forced-air/heatsink-limited environments requiring >125 W dissipation | Select when PCB space is constrained and thermal management uses board copper; not a drop-in replacement for TIP147's through-hole TO-218 footprint |
| BDW53C | TO-220 package; PD = 90 W; VCEO = 100 V; hFE ≥750 @ IC = 5 A; no integrated base shunt resistor | Requires external 10 kΩ base-emitter resistor for reliable turn-off; less robust against EMI-induced false turn-on | Choose where cost sensitivity outweighs reliability in electrically noisy settings; layout must accommodate external resistor |
Compared with MJD127G and BDW53C, the TIP147 offers superior thermal capacity (125 W vs. 30 W or 90 W), integrated turn-off assurance, and proven ruggedness in unclamped inductive switching-making it preferred for industrial motor and power supply designs demanding long-term reliability at full rated current.

FAQ
What is the maximum continuous collector current rating for the TIP147?
The TIP147 has a maximum continuous collector current (IC) rating of 10 Adc at TC = 25°C. This rating assumes proper heatsinking and derates linearly with increasing case temperature - for example, at TC = 100°C, the usable IC drops to approximately 5 A. The device also supports 15 A peak current for short durations (5 ms, 10% duty cycle), making it suitable for pulsed load applications like solenoid actuation. Always verify actual thermal conditions using RJC = 1.0 °C/W and ambient temperature constraints.
Does the TIP147 include an internal base-emitter resistor, and what is its function?
Yes, the TIP147 incorporates a monolithic base-emitter shunt resistor. Its primary function is to ensure reliable turn-off by providing a defined discharge path for base charge, preventing unintended conduction due to leakage currents or noise coupling. This eliminates the need for an external pull-down resistor in most applications, simplifying PCB layout and improving robustness in electrically noisy industrial environments. The resistor value is optimized within the die structure and is not separately specified in the datasheet.
Can the TIP147 be used in complementary pairs with NPN devices, and which part is recommended?
Yes, the TIP147 is explicitly designed as the PNP complement to the NPN TIP142 - both share identical voltage (100 V VCEO), current (10 A IC), power (125 W PD), and thermal (RJC = 1.0 °C/W) ratings, and are listed together as Preferred Devices in the ON Semiconductor datasheet. This symmetry ensures matched gain, saturation, and thermal behavior in push-pull or Class AB amplifier outputs. Using mismatched pairs (e.g., TIP147 with TIP141) introduces imbalance in conduction thresholds and thermal runaway risk.
What is the safe operating area (SOA) limitation for the TIP147 under inductive switching conditions?
The TIP147 is characterized for unclamped inductive switching with a rated energy limit of 100 mJ, verified per Figure 7 in the official datasheet. This means it can safely absorb 100 millijoules of stored inductive energy during turn-off without second breakdown - for example, with a 100 mH coil carrying 1.42 A. Exceeding this limit risks immediate failure. Designers must calculate L × I²/2 for their specific load and either add clamping (e.g., flyback diode + snubber) or select lower-inductance actuators to remain within the TIP147 SOA boundary.
Is the TIP147 available in a lead-free (Pb-free) version, and how is it marked?
Yes, the Pb-free version is designated TIP147G and is fully compliant with RoHS Directive 2011/65/EU. It shares identical electrical, thermal, and mechanical specifications with the standard TIP147, including the same TO-218 (SOT-93) package and 125 W power rating. The "G" suffix appears in the device marking (e.g., "TIP147G") and ordering code, and the packaging label clearly indicates Pb-free status. No requalification is needed when migrating from TIP147 to TIP147G in existing designs.
