STP57N65M5 Equivalent & Substitute Parts

Part Overview

The STP57N65M5 is an N-Channel MOSFET rated for 650V drain-to-source voltage with 42A continuous drain current at 25°C. This device is manufactured by STMicroelectronics as part of the MDmesh™ V series and is housed in a TO-220-3 package for through-hole mounting applications. The part is Active in product status and fully compliant with RoHS3 and REACH regulations.

Substitute parts are necessary when TO-220 package availability is limited or when alternative package formats (TO-247-3 or TO-247-4L) are required for specific circuit board layouts or thermal management strategies. All substitute parts maintain identical electrical performance characteristics while offering different mechanical packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STP57N65M5 is determined by electrical parameter equivalence across the MDmesh™ V series. All substitute parts maintain identical electrical specifications:

Electrical Equivalence Criteria:

• Drain-to-Source Voltage (Vdss): 650V
• Continuous Drain Current (Id): 42A at 25°C
• On-State Resistance (Rds On): 63mOhm @ 21A, 10V
• Gate Threshold Voltage (Vgs(th)): 5V @ 250µA
• Gate Charge (Qg): 98nC @ 10V
• Input Capacitance (Ciss): 4200pF @ 100V
• Maximum Power Dissipation: 250W
• Operating Temperature: 150°C (TJ)

Package Variations: Substitute parts differ only in mechanical packaging format while maintaining through-hole mounting type. The STP57N65M5 uses TO-220-3 package, while substitutes employ TO-247-3 or TO-247-4L packages. These package differences affect printed circuit board layout, lead configuration, and thermal interface requirements but do not alter electrical performance or functional operation.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are Active products manufactured by STMicroelectronics and maintain full compliance with RoHS3 and REACH regulations. Selection between the STP57N65M5 and its substitutes is determined by package format requirements and circuit board design constraints.

TO-220-3 Package (STP57N65M5): Select this configuration when existing printed circuit board layouts are designed for TO-220 lead spacing and mounting hole patterns. This package offers standard three-lead through-hole configuration.

TO-247-3 Package (STW57N65M5 and STWA57N65M5): Select either TO-247-3 variant when circuit board design accommodates the larger TO-247 package footprint. Both parts are electrically identical; selection depends on inventory availability and lead time requirements.

TO-247-4L Package (STW57N65M5-4): Select this configuration when four-lead through-hole mounting is required or when circuit design specifies the TO-247-4L package format. This variant provides an additional lead configuration option within the same electrical performance envelope.

All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. All parts are classified under ECCN EAR99 and HTSUS 8541.29.0095 for regulatory and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the STP57N65M5 be directly replaced with STW57N65M5 on an existing circuit board?

A: Direct replacement requires circuit board redesign. The STP57N65M5 uses TO-220-3 package while STW57N65M5 uses TO-247-3 package. Lead spacing, hole patterns, and mounting hole positions differ between these packages. Physical modification of the printed circuit board is necessary to accommodate the different package format.

Q: Are all substitute parts electrically identical to the STP57N65M5?

A: Yes. All substitute parts maintain identical electrical specifications including Vdss (650V), Id (42A), Rds On (63mOhm), Vgs(th) (5V), Qg (98nC), Ciss (4200pF), and maximum power dissipation (250W). Electrical performance and functional operation are equivalent across all listed parts.

Q: What is the difference between STW57N65M5 and STW57N65M5-4?

A: Both parts are electrically identical N-Channel MOSFETs rated for 650V and 42A. The primary difference is package configuration: STW57N65M5 uses TO-247-3 (three-lead) package while STW57N65M5-4 uses TO-247-4L (four-lead) package. Lead configuration and printed circuit board mounting patterns differ accordingly.

Q: Can I use STWA57N65M5 as a substitute for STP57N65M5?

A: STWA57N65M5 is electrically equivalent to STP57N65M5 but uses TO-247-3 package instead of TO-220-3. Circuit board redesign is required to accommodate the different package footprint and lead spacing.

Q: Are there any thermal performance differences between these substitute parts?

A: All parts maintain identical maximum power dissipation rating of 250W at Tc and identical operating junction temperature of 150°C (TJ). Thermal performance is equivalent across all listed parts. Thermal interface design and heat sink requirements depend on circuit board layout and package mounting configuration rather than electrical specifications.

Q: What is the inventory status of these substitute parts?

A: STP57N65M5 (TO-220-3) has 4767 pieces in stock. STW57N65M5 (TO-247-3) has 19143 pieces in stock. STW57N65M5-4 (TO-247-4L) has 1700 pieces in stock. STWA57N65M5 (TO-247-3) has 2100 pieces in stock. All parts are new original stock.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts including STP57N65M5, STW57N65M5, STW57N65M5-4, and STWA57N65M5 are ROHS3 Compliant and REACH Unaffected. All parts carry Moisture Sensitivity Level 1 (Unlimited).
