BMS3003 MOSFET P-Channel 60V 78A TO-220ML Equivalent & Substitute Parts

Part Overview

The BMS3003 is a P-Channel MOSFET manufactured by onsemi, rated for 60V drain-to-source voltage with 78A continuous drain current in a Through Hole TO-220ML package. This device is classified as Obsolete product status, making identification of equivalent and substitute components necessary for ongoing design support, production continuity, and system maintenance.

The BMS3003 serves applications requiring P-Channel switching and linear regulation in moderate to high-current circuits operating at voltages up to 60V. Obsolescence requires engineers to evaluate functionally compatible alternatives that maintain electrical and mechanical compatibility within the target application.

Substitute Part Grouping Explanation

Substitution of the BMS3003 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Criteria:

1. FET Type: P-Channel topology is mandatory for functional equivalence
2. Drain to Source Voltage (Vdss): Minimum 60V rating required; higher ratings are acceptable
3. Continuous Drain Current (Id): Minimum 78A at rated temperature; higher ratings are acceptable
4. Mounting Type: Through Hole configuration required for mechanical compatibility
5. Package / Case: TO-220-3 footprint required for PCB layout compatibility
6. Gate Charge (Qg): Lower values improve switching performance; values up to 285 nC are acceptable
7. Rds On (Max): Lower on-resistance improves efficiency; values up to 6.5 mOhm are acceptable
8. Operating Temperature Range: Minimum -55°C to 150°C required; extended ranges are acceptable
9. Vgs (Max): ±20V gate voltage rating required for drive circuit compatibility

The substitute part SUP90P06-09L-E3 meets all critical substitution criteria and is classified as Active product status, providing long-term availability and design support.

Parameter Comparison

Engineering Selection Recommendations

SUP90P06-09L-E3 as Primary Substitute for BMS3003:

The SUP90P06-09L-E3 qualifies as a direct substitute based on the following engineering criteria:

1. Electrical Compatibility: Both devices share identical Vdss (60V) and Vgs (Max) (±20V) ratings. The substitute provides higher continuous drain current (90A vs. 78A), exceeding the original specification and providing design margin.

2. Mechanical Compatibility: Both devices use Through Hole mounting in TO-220-3 package configuration, ensuring PCB footprint and thermal interface compatibility without layout modification.

3. Product Status Advantage: The SUP90P06-09L-E3 is classified as Active product status, ensuring long-term availability, manufacturing continuity, and technical support. The BMS3003 Obsolete status creates supply chain risk.

4. Compliance and Certification: The SUP90P06-09L-E3 carries ROHS3 Compliant certification, meeting modern environmental and regulatory requirements. Both devices share identical MSL (1 - Unlimited) and ECCN (EAR99) classifications.

5. Performance Characteristics: The substitute exhibits lower gate charge (240 nC vs. 285 nC) and lower input capacitance (9200 pF vs. 13200 pF), resulting in improved switching speed and reduced drive circuit loading. Extended operating temperature range (-55°C to 175°C vs. -55°C to 150°C) provides additional thermal margin.

6. On-Resistance Trade-off: The substitute exhibits higher Rds On (9.3 mOhm @ 30A, 10V vs. 6.5 mOhm @ 39A, 10V). This parameter difference requires evaluation within the specific application thermal budget. Higher current rating and superior thermal dissipation capability (250W Tc vs. 40W Tc) offset this characteristic in most applications.

Selection Guidance:

Use SUP90P06-09L-E3 as the recommended substitute for new designs and production continuity. For applications with strict on-resistance requirements below 6.5 mOhm, conduct thermal analysis to confirm the substitute's thermal performance compensates for the higher on-resistance specification.

Frequently Asked Questions (FAQ)

Q: Can SUP90P06-09L-E3 directly replace BMS3003 without PCB modification?

A: Yes. Both devices use identical TO-220-3 Through Hole package configuration and pin assignment. No PCB layout changes are required for mechanical and electrical interface compatibility.

Q: What is the significance of the higher continuous drain current in SUP90P06-09L-E3 (90A vs. 78A)?

A: The higher current rating provides design margin and allows the substitute to operate at lower junction temperature for equivalent power dissipation. This improves reliability and extends device lifetime in the application.

Q: How does the higher Rds On of SUP90P06-09L-E3 (9.3 mOhm vs. 6.5 mOhm) affect circuit performance?

A: Higher on-resistance increases conduction losses and heat dissipation. The substitute's superior thermal capability (250W Tc vs. 40W Tc) and higher current rating typically compensate for this difference. Conduct thermal analysis for applications operating near maximum power dissipation limits.

Q: Is the extended operating temperature range of SUP90P06-09L-E3 (-55°C to 175°C vs. -55°C to 150°C) beneficial?

A: Yes. The extended upper temperature limit provides additional thermal margin and allows operation in higher ambient temperature environments without derating. This is advantageous for applications with limited thermal management.

Q: What is the impact of lower gate charge in SUP90P06-09L-E3 (240 nC vs. 285 nC)?

A: Lower gate charge reduces switching time and drive circuit power consumption. This improves switching efficiency and reduces electromagnetic interference (EMI) in high-frequency applications.

Q: Does the lower input capacitance of SUP90P06-09L-E3 (9200 pF vs. 13200 pF) affect drive circuit design?

A: Lower input capacitance reduces gate drive current requirements and improves switching speed. This simplifies drive circuit design and reduces power consumption in the gate drive stage.

Q: Why is the Active product status of SUP90P06-09L-E3 important compared to the Obsolete status of BMS3003?

A: Active product status ensures long-term manufacturing availability, consistent quality, and ongoing technical support from the manufacturer. Obsolete products face supply discontinuation, potential quality degradation, and lack of manufacturer support.

Q: Are there any compliance or regulatory differences between BMS3003 and SUP90P06-09L-E3?

A: Both devices share identical ECCN (EAR99) and MSL (1 - Unlimited) classifications. SUP90P06-09L-E3 carries ROHS3 Compliant certification, meeting modern environmental regulations. Both are REACH Unaffected or Vendor Undefined, indicating no REACH substance of concern restrictions.

Q: Can SUP90P06-09L-E3 be used in applications requiring the exact Rds On specification of BMS3003?

A: Applications with strict on-resistance requirements must evaluate the thermal impact of the higher Rds On specification. Conduct thermal simulation to confirm the substitute's thermal performance remains within acceptable limits for the specific application power dissipation profile.

Q: What packaging format is SUP90P06-09L-E3 supplied in?

A: SUP90P06-09L-E3 is supplied in Tube packaging, suitable for automated assembly processes. Verify packaging compatibility with your procurement and assembly workflow.
