STDLED625 N-Channel MOSFET 620V 5A DPAK Equivalent & Substitute Parts

Part Overview

The STDLED625 is an N-Channel MOSFET manufactured by STMicroelectronics, rated for 620V drain-to-source voltage with 5A continuous drain current at 25°C. This device is housed in a Surface Mount DPAK (TO-252-3) package and is designed for high-voltage switching applications requiring 70W maximum power dissipation. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching or exceeding critical electrical parameters including drain-to-source voltage rating, continuous drain current capability, on-state resistance characteristics, and compatible Surface Mount DPAK packaging. Substitutes must maintain compatibility with the same gate drive voltage and thermal operating range requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the STDLED625 are qualified based on the following critical parameters:

Voltage Rating Compatibility: Substitute devices must have a Drain-to-Source Voltage (Vdss) rating equal to or greater than 620V to ensure safe operation in the same circuit topology.

Current Capability: Substitute devices must support continuous drain current (Id) at 25°C equal to or greater than 5A to handle the same load requirements without thermal derating.

On-State Resistance (Rds On): Substitute devices must maintain Rds On characteristics at 10V gate drive voltage comparable to or better than the main part to ensure efficient switching performance and minimize power loss.

Package Compatibility: All substitute parts must use Surface Mount DPAK (TO-252-3) packaging to ensure mechanical and thermal compatibility with existing PCB layouts and thermal management solutions.

Compliance and Status: Substitute parts must maintain Active product status and RoHS3 compliance to ensure long-term availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

IPD70R1K4P7SAUMA1 (Infineon CoolMOS™ P7 Series): This substitute provides a higher Drain-to-Source Voltage rating of 700V, offering additional voltage margin for high-voltage switching applications. However, the continuous drain current rating of 4A is lower than the STDLED625's 5A specification. This device is suitable for applications where voltage headroom is prioritized and current requirements do not exceed 4A. The part maintains Active product status, RoHS3 compliance, and REACH unaffected status. Extended operating temperature range (-40°C to 150°C) provides broader thermal flexibility compared to the main part.

SPD03N60C3ATMA1 (Infineon): This substitute provides a Drain-to-Source Voltage rating of 600V, which is marginally lower than the STDLED625's 620V specification. The continuous drain current rating of 3.2A is significantly lower than the main part's 5A capability. This device is suitable only for applications with reduced current requirements and lower voltage stress margins. The part maintains Active product status, RoHS3 compliance, and REACH unaffected status. Extended operating temperature range (-55°C to 150°C) provides superior low-temperature performance.

Both substitute parts maintain compatible Surface Mount DPAK packaging, matching gate drive voltage of 10V, and equivalent on-state resistance characteristics. Selection between substitutes depends on specific application requirements for voltage margin, current capacity, and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can the IPD70R1K4P7SAUMA1 directly replace the STDLED625 in all applications?

A: The IPD70R1K4P7SAUMA1 provides higher voltage rating (700V vs. 620V) but lower continuous drain current (4A vs. 5A). Direct replacement is suitable only for applications where continuous drain current does not exceed 4A. Applications requiring the full 5A current capability must use the original STDLED625 or equivalent parts with matching or higher current ratings.

Q: What are the key differences between the two substitute parts?

A: The IPD70R1K4P7SAUMA1 offers higher voltage rating (700V) with lower current (4A), while the SPD03N60C3ATMA1 offers lower voltage rating (600V) with even lower current (3.2A). The IPD70R1K4P7SAUMA1 is the preferred substitute when voltage margin is critical. The SPD03N60C3ATMA1 is suitable only for reduced-current applications below 3.2A.

Q: Are all substitute parts available in the same DPAK package?

A: Yes. All listed substitute parts use the Surface Mount TO-252-3 DPAK (2 Leads + Tab) package, ensuring mechanical and thermal compatibility with existing PCB layouts designed for the STDLED625.

Q: Do the substitute parts meet the same compliance requirements as the STDLED625?

A: Yes. All substitute parts are RoHS3 compliant, REACH unaffected, and maintain Active product status, ensuring regulatory alignment and long-term availability.

Q: What is the impact of lower power dissipation ratings in the substitute parts?

A: The IPD70R1K4P7SAUMA1 (23W) and SPD03N60C3ATMA1 (38W) have lower maximum power dissipation ratings compared to the STDLED625 (70W). This reflects their lower current ratings and indicates reduced thermal load in applications operating within their specified current limits. Applications requiring the full 70W dissipation capability must use the original STDLED625.

Q: Can gate drive voltage be different between the main part and substitutes?

A: No. All parts in this comparison use 10V as the drive voltage for maximum Rds On specification, ensuring consistent gate drive requirements and switching performance across the selection.
