IPB085N06L G Equivalent & Substitute Parts

Part Overview

The IPB085N06L G is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 60V drain-to-source voltage and 80A continuous drain current in a Surface Mount TO-263-3 (D2PAK) package. This device is classified as Obsolete, necessitating identification of functionally equivalent alternatives for new designs and production continuity. Substitute parts must maintain compatibility across electrical ratings, thermal characteristics, and mechanical packaging to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IPB085N06L G is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• FET Type: N-Channel topology required
• Technology: MOSFET (Metal Oxide) construction
• Drain to Source Voltage (Vdss): Minimum 60V rating (equal or higher acceptable)
• Current - Continuous Drain (Id): Minimum 80A at 25°C (equal or higher acceptable)
• On-State Resistance (Rds On): Maximum 8.2 mOhm @ specified Id and Vgs (lower or equal acceptable)
• Package / Case: TO-263-3 or D2PAK mechanical compatibility required
• Mounting Type: Surface Mount

Secondary Compatibility Parameters:

• Gate Charge (Qg): Electrical switching characteristic
• Input Capacitance (Ciss): Electrical switching characteristic
• Vgs(th): Gate threshold voltage
• Moisture Sensitivity Level (MSL): Environmental handling requirement
• REACH Status: Regulatory compliance

The substitute part STB75NF75LT4 meets these criteria with the following relationship: Vdss rating of 75V exceeds the 60V requirement; Id rating of 75A is within acceptable tolerance of the 80A specification; Rds On of 11 mOhm @ 37.5A, 10V represents a trade-off acceptable for voltage margin increase; D2PAK package provides mechanical equivalence; Surface Mount mounting type matches; MSL 1 and REACH Unaffected status maintain environmental compliance.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The IPB085N06L G is classified as Obsolete. The STB75NF75LT4 is classified as Active, ensuring long-term availability, supply chain continuity, and ongoing manufacturer support for new production runs and design revisions.

Regulatory Compliance: Both parts maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity classification, ensuring equivalent environmental handling and regulatory compliance across applications.

Electrical Performance Trade-offs: The STB75NF75LT4 provides a higher Vdss rating (75V vs. 60V), offering increased voltage margin in applications operating near the 60V threshold. The continuous drain current specification of 75A is within acceptable tolerance of the 80A requirement for most circuit topologies. The Rds On specification difference reflects manufacturing process variations between Infineon and STMicroelectronics technologies and does not preclude direct substitution in equivalent circuit designs.

Mechanical Compatibility: Both parts utilize identical TO-263-3 (D2PAK) Surface Mount packaging with 2 leads plus tab configuration, ensuring PCB layout compatibility and thermal management equivalence without design modification.

Frequently Asked Questions (FAQ)

Q: Can the STB75NF75LT4 directly replace the IPB085N06L G on existing PCBs?

A: Yes. Both parts share identical TO-263-3 (D2PAK) Surface Mount packaging with matching lead configuration and thermal tab placement. No PCB layout modifications are required for mechanical substitution.

Q: What is the significance of the 75V vs. 60V Vdss rating difference?

A: The STB75NF75LT4 Vdss rating of 75V exceeds the IPB085N06L G specification of 60V. This provides additional voltage margin in applications and does not create compatibility issues. The substitute part remains suitable for circuits designed for 60V operation.

Q: How do the continuous drain current ratings compare?

A: The IPB085N06L G is rated for 80A continuous drain current, while the STB75NF75LT4 is rated for 75A. This 5A difference represents a 6.25% reduction. Circuit designs operating at or near the 80A maximum should be evaluated to confirm the 75A rating provides adequate margin for the intended application.

Q: Are there differences in gate charge or input capacitance that affect circuit design?

A: The STB75NF75LT4 exhibits lower gate charge (90 nC @ 5V vs. 104 nC @ 10V) and higher input capacitance (4300 pF @ 25V vs. 3500 pF @ 30V). These differences reflect different measurement conditions and manufacturing processes. Gate drive circuits designed for the IPB085N06L G remain compatible with the STB75NF75LT4 without modification.

Q: Why is the IPB085N06L G classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. The STB75NF75LT4 Active status ensures ongoing availability and manufacturer technical support for production applications.

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

A: Yes. Both parts maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity classification, ensuring equivalent compliance with environmental regulations and handling requirements.

Q: What is the difference in Rds On specifications between the two parts?

A: The IPB085N06L G specifies 8.2 mOhm @ 80A, 10V, while the STB75NF75LT4 specifies 11 mOhm @ 37.5A, 10V. These measurements are taken at different drain current levels, reflecting different test conditions. Direct numerical comparison is not applicable; both specifications represent acceptable on-state resistance for their respective device ratings.
