DPLS4140E-13 Equivalent & Substitute Parts

Part Overview

The DPLS4140E-13 is a PNP bipolar junction transistor manufactured by Diodes Incorporated, rated for 140 V collector-emitter breakdown voltage and 4 A maximum collector current in a surface mount SOT-223-3 package. This device is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. Alternative equivalent parts are available from Diodes Incorporated and other manufacturers that maintain the same electrical and mechanical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the DPLS4140E-13 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Transistor type: PNP
Collector current rating: 4 A (minimum)
Collector-emitter breakdown voltage: 140 V (minimum)
Package type: SOT-223-3 or SOT-223-4 (surface mount)
DC current gain: 100 @ 1A, 5V (minimum)
Operating temperature range: -55°C to 150°C (minimum)

Acceptable Parameter Variations:

Power dissipation may exceed 1 W (higher ratings are acceptable)
Transition frequency may differ (no minimum requirement specified)
Vce saturation may vary within acceptable limits for the application
Collector cutoff current (ICBO) may vary

Parts are grouped into two categories:

Direct Equivalents (Diodes Incorporated): ZX5T955GTA, FZT955TA, and ZXTP2014GTA maintain all critical electrical parameters while offering active product status and higher power ratings (3 W).

Cross-Manufacturer Equivalents: CZT955 TR PBFREE (Central Semiconductor Corp), PBHV9414ZX (Nexperia USA Inc.), and NZT753 (Fairchild Semiconductor) meet the core electrical requirements but may have minor parameter deviations.

Non-Equivalent Parts: PZT2907AT1G and PZT2907AT3G do not qualify as substitutes due to insufficient collector current (600 mA vs. 4 A required) and reduced collector-emitter breakdown voltage (60 V vs. 140 V required).

Engineering Selection Recommendations

Recommended Direct Substitutes (Diodes Incorporated):

ZX5T955GTA, FZT955TA, and ZXTP2014GTA are the primary substitutes for DPLS4140E-13. All three parts are manufactured by Diodes Incorporated, maintain identical electrical specifications for collector current, breakdown voltage, and DC current gain, and carry active product status. These parts offer improved power dissipation ratings (3 W vs. 1 W), providing design margin for thermal management. All are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Cross-Manufacturer Alternatives:

CZT955 TR PBFREE (Central Semiconductor Corp) meets all critical electrical parameters and offers the highest transition frequency (200 MHz). This part is active and RoHS3 compliant.

PBHV9414ZX (Nexperia USA Inc.) is qualified to AEC-Q100 automotive standards and carries active product status. However, power dissipation is limited to 650 mW, which is below the original 1 W specification. This part is suitable only for applications where thermal dissipation does not exceed 650 mW.

Not Recommended:

NZT753 (Fairchild Semiconductor) has a reduced collector-emitter breakdown voltage of 100 V, which is insufficient for applications requiring the full 140 V rating. This part does not qualify as a direct substitute.

PZT2907AT1G and PZT2907AT3G (onsemi) have maximum collector current of 600 mA and breakdown voltage of 60 V, making them unsuitable for this application.

Frequently Asked Questions (FAQ)

Q: Can ZX5T955GTA be used as a direct replacement for DPLS4140E-13?

A: Yes. ZX5T955GTA meets all critical electrical parameters: 4 A collector current, 140 V breakdown voltage, 100 hFE minimum, and SOT-223-3 package. The part is manufactured by the same company (Diodes Incorporated) and carries active product status. The increased power rating (3 W vs. 1 W) provides additional thermal margin.

Q: What is the difference between FZT955TA and ZX5T955GTA?

A: Both parts are manufactured by Diodes Incorporated and meet the same electrical specifications for collector current, breakdown voltage, and DC current gain. FZT955TA has a slightly lower transition frequency (110 MHz vs. 120 MHz) and marginally higher Vce saturation (370 mV vs. 360 mV at 300 mA, 3 A). Both are suitable substitutes.

Q: Why is NZT753 not recommended as a substitute?

A: NZT753 has a maximum collector-emitter breakdown voltage of 100 V, which is 40 V below the DPLS4140E-13 specification of 140 V. This part cannot be used in applications requiring the full voltage rating and does not qualify as an equivalent.

Q: Can PBHV9414ZX be used in high-power applications?

A: PBHV9414ZX has a maximum power dissipation of 650 mW, which is below the original 1 W specification. This part is suitable only for applications where thermal dissipation does not exceed 650 mW. For applications requiring the full 1 W or higher power handling, use ZX5T955GTA, FZT955TA, or ZXTP2014GTA instead.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts (ZX5T955GTA, FZT955TA, ZXTP2014GTA, CZT955 TR PBFREE, and PBHV9414ZX) are RoHS3 compliant. NZT753 compliance status is not specified in the provided data.

Q: What is the difference between SOT-223-3 and SOT-223-4 packages?

A: Both are surface mount packages with identical pin pitch and footprint compatibility. SOT-223-3 has three leads (Collector, Base, Emitter), while SOT-223-4 has four leads with an additional thermal pad. For PCB layout purposes, verify footprint compatibility with your design before substitution.

Q: Is CZT955 TR PBFREE suitable for automotive applications?

A: CZT955 TR PBFREE is not specified with automotive qualification. PBHV9414ZX carries AEC-Q100 qualification for automotive use. If automotive qualification is required, use PBHV9414ZX, subject to the power dissipation limitation noted above.

Q: What packaging options are available for substitutes?

A: ZX5T955GTA is available in Cut Tape (CT). FZT955TA and ZXTP2014GTA are available in Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® respectively. CZT955 TR PBFREE and PBHV9414ZX are available in Tape & Reel (TR). Select packaging based on your procurement and assembly requirements.
