ATP101-TL-H P-Channel MOSFET 30V 25A Equivalent & Substitute Parts

Part Overview

The ATP101-TL-H is a P-Channel MOSFET manufactured by onsemi, rated for 30V drain-to-source voltage and 25A continuous drain current at 25°C in the ATPAK surface mount package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The ATP101-TL-H serves applications requiring P-Channel switching and linear regulation in power management circuits. Substitution is required due to product discontinuation and limited inventory availability relative to active alternatives.

Substitute Part Grouping Explanation

Substitution of the ATP101-TL-H is determined by the following electrical and mechanical parameters:

Primary Substitution Criteria:

FET Type: P-Channel
Drain-to-Source Voltage (Vdss): 30V minimum
Continuous Drain Current (Id): 25A or greater at rated temperature
Gate-Source Voltage (Vgs): ±20V or greater
On-Resistance (Rds On): Comparable or lower at specified gate voltage
Surface Mount packaging with compatible footprint or pinout

Secondary Compatibility Factors:

Gate Charge (Qg): Lower values reduce switching losses
Input Capacitance (Ciss): Lower values improve switching speed
Power Dissipation capability: Minimum 30W at case temperature
Operating Temperature range: Minimum 150°C junction temperature
RoHS3 compliance and REACH unaffected status

Substitute parts are grouped into two categories: MFR Recommended (direct onsemi alternative) and Similar (functionally equivalent from other manufacturers). All listed substitutes meet or exceed the electrical specifications of the ATP101-TL-H within their respective package constraints.

Engineering Selection Recommendations

FDD6685 (onsemi PowerTrench®)

The FDD6685 is the manufacturer-recommended substitute from onsemi. This part is in active production status, ensuring long-term availability and supply chain stability. The FDD6685 meets all electrical requirements of the ATP101-TL-H with improved on-resistance (20 mOhm vs. 30 mOhm) and extended operating temperature range (−55°C to 175°C vs. 150°C maximum). The TO-252-3 DPAK package requires PCB layout modification from the original ATPAK footprint. RoHS3 compliance and REACH unaffected status are maintained.

DMP3028LK3-13 (Diodes Incorporated)

The DMP3028LK3-13 is an active product offering superior continuous drain current (27A at case temperature) and lower on-resistance (25 mOhm at 7A, 10V). This part is suitable for applications requiring higher current capacity within the same voltage class. The TO-252-3 DPAK package is compatible with standard surface mount assembly processes. Operating temperature range extends to −55°C to 150°C. RoHS3 compliance and REACH unaffected status are confirmed.

AOD417 (Alpha & Omega Semiconductor Inc.)

The AOD417 provides electrical equivalence to the ATP101-TL-H with matching 25A continuous drain current and identical gate-source voltage rating. However, this part is classified as obsolete, limiting its suitability for new designs requiring long-term component availability. The TO-252 DPAK package is compatible with standard surface mount processes. RoHS3 compliance is maintained.

STD26P3LLH6 (STMicroelectronics DeepGATE™ STripFET™ VI)

The STD26P3LLH6 offers the lowest gate charge (12 nC) among substitute options, providing reduced switching losses and improved switching speed. Continuous drain current is rated at 12A (case temperature), which is lower than the ATP101-TL-H specification. This part is suitable for applications where switching performance is prioritized over maximum current capacity. The DPAK package is compatible with standard surface mount assembly. Operating temperature extends to 175°C. RoHS3 compliance and REACH unaffected status are confirmed.

Frequently Asked Questions (FAQ)

Q: Can the FDD6685 directly replace the ATP101-TL-H without PCB modification?

A: The FDD6685 uses the TO-252-3 DPAK package, while the ATP101-TL-H uses the ATPAK package. Although both are surface mount packages with 2 leads plus tab, the footprint dimensions differ. PCB layout modification is required for direct substitution.

Q: What is the primary advantage of the DMP3028LK3-13 over the ATP101-TL-H?

A: The DMP3028LK3-13 provides higher continuous drain current (27A at case temperature) and lower on-resistance (25 mOhm at 7A, 10V), resulting in reduced power dissipation in high-current applications. The part is also in active production status.

Q: Is the AOD417 suitable for new product designs?

A: The AOD417 is classified as obsolete. While it provides electrical equivalence to the ATP101-TL-H, its discontinued status makes it unsuitable for new designs requiring long-term component availability and supply chain continuity.

Q: Which substitute part offers the best switching performance?

A: The STD26P3LLH6 has the lowest gate charge specification (12 nC @ 4.5V), which reduces switching losses and improves switching speed. This characteristic is beneficial in high-frequency switching applications. However, its continuous drain current rating (12A at case temperature) is lower than the ATP101-TL-H.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (FDD6685, AOD417, DMP3028LK3-13, and STD26P3LLH6) are RoHS3 compliant and REACH unaffected, maintaining regulatory compliance with the original ATP101-TL-H.

Q: What is the difference between Ta and Tc current ratings?

A: Ta (ambient temperature) current rating is measured at 25°C ambient conditions. Tc (case temperature) current rating is measured at the specified case temperature, typically higher than ambient. Tc ratings generally reflect higher current capacity due to improved thermal conditions at the device case.

Q: Can the STD26P3LLH6 handle the full 25A continuous current of the ATP101-TL-H?

A: No. The STD26P3LLH6 is rated for 12A continuous drain current at case temperature, which is below the ATP101-TL-H specification of 25A. This part is suitable only for applications requiring 12A or less.

Q: Which substitute offers the widest operating temperature range?

A: Both the FDD6685 and AOD417 offer the widest operating temperature range (−55°C to 175°C), compared to the ATP101-TL-H maximum of 150°C. The DMP3028LK3-13 extends to −55°C to 150°C, and the STD26P3LLH6 reaches 175°C maximum.
