TIP147 PNP Darlington Transistor Equivalent & Substitute Parts

Part Overview

The TIP147 is a PNP Darlington bipolar junction transistor manufactured by onsemi, rated for 100 V collector-emitter breakdown voltage and 10 A maximum collector current in a TO-247-3 through-hole package. The TIP147 carries an obsolete product status, necessitating identification of active equivalent and substitute parts for new designs and ongoing production requirements. Direct equivalents and similar alternatives are available from onsemi and STMicroelectronics with matching or comparable electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TIP147 are classified based on electrical parameter equivalence and package compatibility. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Transistor Type: PNP - Darlington
• Current - Collector (Ic) (Max): 10 A
• Voltage - Collector Emitter Breakdown (Max): 100 V
• Vce Saturation (Max) @ Ib, Ic: 3 V @ 40 mA, 10 A
• Current - Collector Cutoff (Max): 2 mA
• DC Current Gain (hFE) (Min) @ Ic, Vce: 1000 @ 5 A, 4 V
• Operating Temperature Range: -65°C to 150°C (TJ)

Package Considerations:

• Direct equivalents maintain TO-247-3 package compatibility
• Similar alternatives may use TO-220-3 package with reduced power dissipation capability (90 W vs. 125 W)

Compliance Status:

• Direct equivalents prioritize active product status and RoHS3 compliance
• Similar alternatives from alternate manufacturers provide functional equivalence with compliance certifications

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - TIP147G (onsemi):

The TIP147G is the primary direct substitute for the obsolete TIP147. Both parts share identical electrical specifications, including 10 A collector current, 100 V breakdown voltage, 125 W power dissipation, and TO-247-3 package configuration. The TIP147G maintains active product status and achieves RoHS3 compliance, addressing regulatory requirements for new designs. The TIP147G is supplied in tube packaging and is suitable for direct replacement in existing circuit designs without modification.

Similar Alternative - TIP147T (STMicroelectronics):

The TIP147T from STMicroelectronics provides functional equivalence with identical electrical performance in collector current, breakdown voltage, saturation characteristics, and current gain. The primary distinction is the TO-220-3 package configuration, which reduces maximum power dissipation to 90 W compared to the 125 W rating of the TO-247-3 package. The TIP147T is active and RoHS3 compliant. Selection of the TIP147T requires thermal design verification to confirm that the reduced power dissipation capability is acceptable for the application. The TO-220-3 package may require different mounting hardware and thermal management provisions compared to TO-247-3 implementations.

Frequently Asked Questions (FAQ)

Q: Can TIP147G be used as a direct replacement for TIP147?

A: Yes. The TIP147G is electrically and mechanically identical to the TIP147, with matching TO-247-3 package, 10 A collector current, 100 V breakdown voltage, and 125 W power dissipation. The TIP147G is active and RoHS3 compliant, making it the preferred substitute for obsolete TIP147 applications.

Q: What is the primary difference between TIP147G and TIP147T?

A: The TIP147G uses a TO-247-3 package with 125 W maximum power dissipation, while the TIP147T uses a TO-220-3 package with 90 W maximum power dissipation. Electrical specifications for collector current, breakdown voltage, and current gain are identical. Package selection depends on thermal requirements and available mounting space in the application.

Q: Can TIP147T replace TIP147 in all applications?

A: TIP147T provides electrical equivalence but with reduced power dissipation capability (90 W vs. 125 W). Applications requiring sustained power dissipation above 90 W must use TIP147G or the original TIP147. The TO-220-3 package also requires different mounting provisions than TO-247-3. Thermal analysis is required to confirm suitability for each application.

Q: Are there compliance differences between the substitute parts?

A: The TIP147 is RoHS non-compliant. Both TIP147G and TIP147T are RoHS3 compliant. All three parts are REACH Unaffected. For applications subject to RoHS requirements, TIP147G or TIP147T must be selected.

Q: What is the operating temperature range for each part?

A: TIP147 and TIP147G both operate from -65°C to 150°C (TJ). TIP147T specifies a maximum operating temperature of 150°C (TJ) without a stated minimum. For applications requiring operation below 0°C, TIP147G is the appropriate selection.

Q: How do the packages differ mechanically?

A: TIP147 and TIP147G use TO-247-3 packages, which feature three leads and a larger mounting footprint suitable for higher power dissipation. TIP147T uses TO-220-3 package, which has a smaller footprint and different lead configuration. PCB layout and thermal management designs must be adapted when switching between these packages.
