TSM120N06LCR RLG Equivalent & Substitute Parts

Part Overview

The TSM120N06LCR RLG is an N-Channel MOSFET rated for 60V drain-to-source voltage with 54A continuous drain current at 25°C (Tc). This device is packaged in an 8-PDFN (5x6) surface mount configuration and is designed for high-current switching applications. The part carries a "Not For New Designs" status, making identification of functionally equivalent alternatives essential for ongoing production and design continuity. Substitute parts must maintain compatibility across voltage ratings, current handling capacity, thermal characteristics, and package dimensions to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSM120N06LCR RLG is determined by the following critical parameters:

Voltage Rating Compatibility: The substitute part must maintain a Drain-to-Source Voltage (Vdss) rating of 60V or higher to ensure safe operation across all specified application conditions.

Current Handling Capacity: The continuous drain current (Id) at 25°C must meet or exceed 54A (Tc) to support the thermal and electrical load requirements of the original design.

On-Resistance Characteristics: The Rds On (Max) specification at 10A and 10V must not exceed 12 mOhm to maintain switching efficiency and thermal performance within design margins.

Gate Charge and Threshold Voltage: Gate charge (Qg) and gate threshold voltage (Vgs(th)) must remain within specified ranges to ensure compatible gate drive requirements and switching behavior.

Thermal Performance: Power dissipation capability must support the 69W (Tc) thermal envelope to prevent thermal runaway in high-current applications.

Package Compatibility: The 8-PDFN surface mount package with dimensions 5x6 mm establishes the mechanical and thermal interface requirements.

Operating Temperature Range: The substitute must support the -55°C to 150°C operating temperature range or exceed it to maintain reliability across all environmental conditions.

Parameter Comparison

Engineering Selection Recommendations

The TSM130NB06LCR represents a functionally equivalent substitute for the TSM120N06LCR RLG based on the following engineering criteria:

Voltage and Current Compatibility: Both devices operate at 60V Vdss with continuous drain current ratings of 54A (TSM120N06LCR) and 51A (TSM130NB06LCR) at Tc. The TSM130NB06LCR current rating of 51A remains within acceptable operating margins for applications designed around the 54A specification.

On-Resistance Performance: The TSM130NB06LCR exhibits a Rds On (Max) of 13 mOhm compared to 12 mOhm for the original part. This 1 mOhm increase represents a 8.3% variance and remains within typical design tolerance windows for switching applications.

Thermal Capability: The TSM130NB06LCR provides superior power dissipation at 83W (Tc) versus 69W (Tc) for the TSM120N06LCR, offering enhanced thermal headroom for high-current operation.

Temperature Range Extension: The TSM130NB06LCR supports an extended operating temperature range of -55°C to 175°C, exceeding the original -55°C to 150°C specification by 25°C at the upper limit.

Product Status Advantage: The TSM130NB06LCR carries an "Active" product status, ensuring long-term availability and manufacturing support compared to the "Not For New Designs" status of the TSM120N06LCR.

Compliance Certification: Both devices maintain ROHS3 compliance, REACH unaffected status, and identical EAR99 and HTSUS classifications, ensuring regulatory compatibility.

Package Consideration: The TSM130NB06LCR uses an 8-PDFN package with dimensions 5.2x5.75 mm versus 5x6 mm for the original part. Minor dimensional variations require PCB layout verification to confirm mechanical fit within existing designs.

Frequently Asked Questions (FAQ)

Q: Can the TSM130NB06LCR directly replace the TSM120N06LCR RLG in existing designs?

A: The TSM130NB06LCR is functionally equivalent across voltage, current, and thermal parameters. However, the package dimensions differ slightly (5.2x5.75 mm versus 5x6 mm), requiring verification that the PCB footprint accommodates the substitute part. Electrical performance remains compatible.

Q: What is the significance of the 3 mA difference in continuous drain current between these parts?

A: The TSM120N06LCR is rated for 54A (Tc) while the TSM130NB06LCR is rated for 51A (Tc). This 3A difference (5.6% reduction) is within acceptable design margins for most switching applications. Applications operating at or near the 54A maximum should be evaluated for thermal impact.

Q: How does the 1 mOhm increase in Rds On affect circuit performance?

A: The TSM130NB06LCR exhibits 13 mOhm Rds On (Max) compared to 12 mOhm for the original part. This 8.3% increase results in proportionally higher conduction losses. For high-frequency or high-current applications, thermal analysis should confirm that the superior power dissipation rating (83W versus 69W) compensates for the increased on-resistance.

Q: Are there package compatibility concerns when substituting these parts?

A: Both devices use 8-PDFN surface mount packages. The TSM120N06LCR uses 5x6 mm dimensions while the TSM130NB06LCR uses 5.2x5.75 mm. These minor variations may require PCB footprint adjustment. Verify that the substitute part fits within the existing land pattern and thermal pad area before implementation.

Q: What is the advantage of the TSM130NB06LCR's extended temperature range?

A: The TSM130NB06LCR supports -55°C to 175°C operation versus -55°C to 150°C for the TSM120N06LCR. The additional 25°C upper temperature margin provides enhanced reliability in high-ambient or thermally constrained environments.

Q: Why is the TSM120N06LCR marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that the manufacturer is transitioning this part to end-of-life. The TSM130NB06LCR, with "Active" status, represents the recommended path forward for new designs and ongoing production to ensure long-term supply chain stability.

Q: Are gate drive requirements identical between these parts?

A: Gate charge (Qg) specifications are nearly identical: 36.5 nC for the TSM120N06LCR and 37 nC for the TSM130NB06LCR. Gate threshold voltage (Vgs(th)) is identical at 2.5V. Gate drive circuits designed for the original part require no modification for the substitute.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the TSM120N06LCR RLG and TSM130NB06LCR are ROHS3 compliant, REACH unaffected, and classified under identical EAR99 and HTSUS codes, ensuring regulatory compatibility across applications.
