AOD512 MOSFET N-Channel 30V Equivalent & Substitute Parts

Part Overview

The AOD512 is an N-Channel MOSFET manufactured by Alpha & Omega Semiconductor Inc., rated for 30V drain-to-source voltage with continuous drain current of 27A (Ta) and 70A (Tc) in a Surface Mount TO-252 (DPAK) package. This device is classified as Active product status and is RoHS3 compliant. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate components with enhanced electrical performance within the same voltage and package class.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AOD512 are qualified based on the following electrical and mechanical parameters:

Substitution Criteria:

• Drain-to-Source Voltage (Vdss): Equal to or greater than 30V
• Package Type: TO-252-3 (DPAK) Surface Mount configuration
• FET Type: N-Channel MOSFET technology
• Operating Temperature Range: Minimum -55°C to 175°C
• RoHS3 Compliance: Required
• Moisture Sensitivity Level: MSL 1 or equivalent

The IPD90N03S4L02ATMA1 qualifies as a substitute because it maintains the same 30V voltage rating, uses identical TO-252-3 DPAK packaging, operates across the same temperature range, and meets RoHS3 compliance requirements. The substitute part provides enhanced continuous drain current capability (90A Tc versus 70A Tc) and improved thermal performance, making it suitable for applications requiring higher current capacity within the same voltage and package constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (AOD512): The AOD512 is suitable for applications requiring a 30V N-Channel MOSFET with moderate current handling (27A Ta, 70A Tc) in a compact TO-252 DPAK package. This part maintains Active product status with full RoHS3 compliance and MSL 1 rating, ensuring long-term availability and environmental regulatory adherence.

Substitute Part Selection (IPD90N03S4L02ATMA1): The IPD90N03S4L02ATMA1 is suitable when higher continuous drain current capacity (90A Tc) is required within the same 30V voltage rating and TO-252 DPAK package footprint. This Infineon OptiMOS™ series device maintains identical compliance certifications (RoHS3, MSL 1) and operating temperature range (-55°C to 175°C). The substitute part exhibits lower on-resistance (2.2mOhm @ 90A, 10V) and higher power dissipation capability (136W Tc), supporting applications with increased thermal and current demands.

Both parts are Active status products with equivalent regulatory compliance, ensuring interchangeability within the specified electrical and mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the IPD90N03S4L02ATMA1 directly replace the AOD512 in existing designs?

A: Yes, the IPD90N03S4L02ATMA1 is a direct substitute for the AOD512. Both devices share identical 30V drain-to-source voltage rating, TO-252-3 DPAK package configuration, and Surface Mount mounting type. Pin configuration and package dimensions are equivalent, allowing direct PCB-level substitution without layout modifications.

Q: What are the key differences between these two parts?

A: The primary differences are continuous drain current capacity and power dissipation. The IPD90N03S4L02ATMA1 provides 90A (Tc) versus the AOD512's 70A (Tc), with corresponding power dissipation of 136W (Tc) versus 83W (Tc). The substitute part also exhibits slightly lower on-resistance (2.2mOhm @ 90A, 10V) and higher gate charge (140 nC @ 10V). These enhancements make the Infineon device suitable for higher-current applications.

Q: Are both parts RoHS3 compliant?

A: Yes, both the AOD512 and IPD90N03S4L02ATMA1 are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both parts are REACH unaffected and classified under ECCN EAR99.

Q: What is the operating temperature range for both devices?

A: Both the AOD512 and IPD90N03S4L02ATMA1 operate across the identical temperature range of -55°C to 175°C (TJ), ensuring thermal compatibility across industrial and extended-temperature applications.

Q: Does the higher gate charge of the IPD90N03S4L02ATMA1 affect circuit design?

A: The IPD90N03S4L02ATMA1 has a gate charge of 140 nC @ 10V compared to the AOD512's 64 nC @ 10V. This higher gate charge requires proportionally more energy for gate switching. Circuit designs must account for this difference in gate driver capability and switching speed characteristics. The higher input capacitance (9750 pF @ 25V versus 3430 pF @ 15V) also affects gate drive circuit performance.

Q: Are there any package or pinout differences between these parts?

A: No. Both devices use the TO-252-3 DPAK (2 Leads + Tab) package with identical pin configuration and mechanical dimensions. The package designation SC-63 applies to both parts, confirming physical and electrical compatibility.

Q: What is the maximum gate voltage for each device?

A: The AOD512 supports a maximum gate voltage (Vgs Max) of ±20V, while the IPD90N03S4L02ATMA1 supports ±16V. Circuit designs must ensure gate drive voltage does not exceed the lower ±16V limit when using the Infineon substitute.
