STW63N65DM2 Equivalent & Substitute Parts

Part Overview

The STW63N65DM2 is an N-Channel MOSFET rated for 650V drain-to-source voltage with 60A continuous drain current at 25°C, housed in a TO-247-3 through-hole package. Manufactured by STMicroelectronics as part of the MDmesh™ series, this device is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance, voltage ratings, current ratings, and thermal characteristics are maintained across the same or compatible package configurations, enabling direct or near-direct circuit board replacement without performance degradation.

Substitute Part Grouping Explanation

Substitution eligibility for the STW63N65DM2 is determined by matching the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Drain to Source Voltage (Vdss): 650V
• Continuous Drain Current (Id) @ 25°C: 60A (Tc)
• On-State Resistance (Rds On): 50mOhm @ 30A, 10V
• Gate Threshold Voltage (Vgs(th)): 5V @ 250µA
• Gate Charge (Qg): 120nC @ 10V
• Power Dissipation: 446W (Tc)
• Operating Temperature Range: -55°C to 150°C (TJ)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package Classification: TO-247-3 or compatible TO-247 variants
• Technology: N-Channel MOSFET (Metal Oxide)

Compliance & Status:

• Product Status: Active
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts maintain identical or equivalent electrical performance while accommodating minor packaging variations (standard TO-247-3 versus TO-247 Long Leads) and optional automotive qualification grades.

This part is supplied in Tube packaging and features TO-247 Long Leads configuration. Selection of this substitute is appropriate when extended lead length is required for specific PCB layout or mechanical assembly requirements. All electrical performance and compliance characteristics remain equivalent to the STW63N65DM2.

Compliance & Status Alignment: All three parts maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity level (MSL 1), ensuring long-term availability and regulatory alignment across substitute selections.

Frequently Asked Questions (FAQ)

Q: Can STW65N65DM2AG be used as a direct replacement for STW63N65DM2?

A: Yes. The STW65N65DM2AG maintains identical electrical specifications including 650V Vdss, 60A continuous drain current, 50mOhm Rds On, and 446W power dissipation. Both devices are housed in TO-247-3 through-hole packages. The primary difference is automotive-grade qualification (AEC-Q101) on the STW65N65DM2AG and Tube packaging format. Direct PCB substitution is supported.

Q: What is the difference between TO-247-3 and TO-247 Long Leads?

A: Both package types use the same three-pin TO-247 footprint and are mechanically compatible for through-hole mounting. TO-247 Long Leads provides extended lead length, which may be beneficial for specific PCB layouts or mechanical assembly configurations. Electrical performance and thermal characteristics remain identical.

Q: Is the STWA63N65DM2 suitable for automotive applications?

A: The STWA63N65DM2 is a standard-grade device without automotive qualification. For automotive applications requiring AEC-Q101 certification, the STW65N65DM2AG is the appropriate selection.

Q: Are all three parts ROHS3 compliant?

A: Yes. The STW63N65DM2, STW65N65DM2AG, and STWA63N65DM2 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What determines substitution eligibility for these MOSFET parts?

A: Substitution is determined by matching Drain-to-Source Voltage (650V), Continuous Drain Current (60A @ 25°C), On-State Resistance (50mOhm @ 30A, 10V), Gate Threshold Voltage (5V @ 250µA), Gate Charge (120nC @ 10V), Power Dissipation (446W), Operating Temperature Range (-55 to 150°C), and Through-Hole mounting in TO-247-3 or compatible TO-247 packages.

Q: Can packaging format (Bulk vs. Tube) affect electrical performance?

A: No. Packaging format affects only handling, storage, and manufacturing processes. Electrical specifications, thermal characteristics, and performance remain identical regardless of whether the part is supplied in Bulk or Tube format.
