IRLR210ATF N-Channel MOSFET 200V 2.7A Equivalent & Substitute Parts

Part Overview

The IRLR210ATF is an N-Channel MOSFET manufactured by onsemi, rated for 200V drain-to-source voltage with 2.7A continuous drain current at 25°C. The device is housed in a TO-252AA (DPAK) surface mount package and is classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain electrical compatibility across critical parameters including voltage rating, current handling capability, and thermal characteristics while accommodating the same or compatible package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRLR210ATF is determined by strict equivalence across the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: The substitute part must maintain a Drain-to-Source Voltage (Vdss) rating of 200V or greater to ensure safe operation under identical circuit conditions.

Current Handling: The substitute part must support continuous drain current (Id) at or above 2.7A at 25°C to fulfill the same load requirements.

On-State Resistance (Rds On): The substitute part's maximum on-state resistance must not exceed the original specification to prevent excessive power dissipation and thermal stress in the circuit.

Package Compatibility: The substitute part must use the TO-252-3 (DPAK) surface mount package with identical pin configuration to ensure direct board-level replacement without layout modifications.

Gate Drive Voltage: The substitute part must operate with standard gate drive voltages (5V or 10V) to maintain compatibility with existing gate driver circuits.

Temperature Range: The substitute part must support the operating temperature range of -55°C to 150°C or wider to ensure reliability across all application conditions.

Compliance and Availability: The substitute part must have active product status and current manufacturing availability to ensure long-term supply chain viability.

Engineering Selection Recommendations

Primary Substitute: AOD4504

The AOD4504 from Alpha & Omega Semiconductor Inc. is the qualified substitute for the obsolete IRLR210ATF. Both devices share identical voltage ratings (200V Vdss), compatible current handling specifications, and identical TO-252-3 (DPAK) package geometry. The AOD4504 maintains the same moisture sensitivity level (MSL 1) and regulatory compliance status (REACH Unaffected, EAR99).

Availability and Supply Chain: The AOD4504 is classified as an active product with 20,300 pieces in current inventory, ensuring reliable long-term availability compared to the obsolete IRLR210ATF status.

Regulatory and Compliance Alignment: Both parts share identical REACH status, ECCN classification, and HTSUS codes, ensuring no regulatory barriers to substitution.

Thermal Performance: The AOD4504 provides enhanced thermal capability with a maximum power dissipation of 42.5W at Tc compared to 21W for the IRLR210ATF, offering improved thermal headroom in applications requiring sustained current delivery.

Operating Temperature Range: The AOD4504 extends the upper operating temperature limit to 175°C compared to 150°C for the IRLR210ATF, providing additional margin for high-temperature applications.

Gate Drive Considerations: The AOD4504 operates at 10V gate drive voltage compared to 5V for the IRLR210ATF. Existing gate driver circuits must be evaluated to confirm compatibility with the higher drive voltage specification.

Frequently Asked Questions (FAQ)

Q: Can the AOD4504 be used as a direct replacement for the IRLR210ATF without circuit modifications?

A: The AOD4504 shares the same TO-252-3 (DPAK) package footprint and pin configuration, enabling direct board-level replacement. However, gate driver circuits must be evaluated for compatibility with the 10V drive voltage specification of the AOD4504 versus the 5V specification of the IRLR210ATF.

Q: What are the key electrical differences between the IRLR210ATF and AOD4504?

A: The primary differences are gate threshold voltage (2V for IRLR210ATF versus 3.7V for AOD4504), gate charge (9nC at 5V versus 115nC at 10V), and on-state resistance characteristics measured at different current and voltage conditions. Both devices maintain the same 200V voltage rating and support the required current levels.

Q: Why does the AOD4504 have higher gate charge than the IRLR210ATF?

A: Gate charge is measured at the device's specified gate drive voltage. The AOD4504 is characterized at 10V drive voltage while the IRLR210ATF is characterized at 5V. Higher gate drive voltage results in higher gate charge values. Gate driver circuits must be sized accordingly for the AOD4504's 10V specification.

Q: Is the AOD4504 suitable for applications requiring operation at the upper temperature limit of the IRLR210ATF?

A: Yes. The AOD4504 supports an extended operating temperature range of -55°C to 175°C, which encompasses the -55°C to 150°C range of the IRLR210ATF. The AOD4504 provides additional margin for high-temperature applications.

Q: What is the impact of the higher input capacitance (Ciss) of the AOD4504 on circuit performance?

A: The AOD4504 has input capacitance of 328pF at 100V compared to 240pF at 25V for the IRLR210ATF. Higher input capacitance increases gate charge and may affect switching speed and gate driver power dissipation. Gate driver circuits should be evaluated for adequate current sourcing capability.

Q: Are there any compliance or regulatory differences between the two parts?

A: No. Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS codes (8541.29.0095), ensuring no regulatory barriers to substitution.

Q: What is the significance of the AOD4504 being an active product versus the IRLR210ATF being obsolete?

A: Active product status ensures continued manufacturing, quality control, and long-term supply chain availability. The IRLR210ATF's obsolete status indicates discontinued production, making the AOD4504 the appropriate choice for new designs and ongoing production requirements.

Q: Can the AOD4504 handle higher continuous current than the IRLR210ATF?

A: Yes. The AOD4504 supports 6A continuous drain current at Tc compared to 2.7A for the IRLR210ATF, providing enhanced current handling capability. This allows the AOD4504 to support higher load currents or provide additional design margin in existing applications.
