Key Parameters

Substitute Part Grouping Explanation

Substitution of the AON6992 is determined by strict equivalence across the following critical parameters: drain-to-source voltage rating (Vdss), continuous drain current capability (Id), on-resistance (Rds On), gate threshold voltage (Vgs(th)), package type (8-DFN 5x6), surface mount configuration, and dual N-channel asymmetrical topology. All substitute parts must maintain the same voltage class (30V), support equivalent or higher current ratings, preserve on-resistance characteristics within acceptable tolerance, and utilize identical or mechanically compatible packaging.

The AONY36302 and AONY36352 are qualified substitutes based on matching Vdss (30V), equivalent Rds On specifications (5.2mOhm and 5.3mOhm/2mOhm respectively), compatible gate threshold voltages, identical package geometry (8-DFN 5x6), and dual N-channel asymmetrical configuration. Both substitute parts are classified as active products, addressing the obsolescence status of the AON6992.

Parameter Comparison

Engineering Selection Recommendations

The AONY36302 and AONY36352 are both qualified substitutes for the obsolete AON6992. Selection between these alternatives is based on product availability, compliance requirements, and specific application parameters.

AONY36302 is recommended for applications requiring manufacturer-specified active product status with standard FET feature classification. This part maintains the 5.2mOhm on-resistance specification identical to the AON6992 and supports continuous drain currents of 20A (Ta) and 51A (Tc), providing equivalent or superior performance within the 30V voltage class.

AONY36352 is recommended for applications where Tape & Reel packaging is required and where the dual on-resistance specifications (5.3mOhm and 2mOhm) and dual gate threshold voltage specifications (2.1V and 1.9V) are compatible with circuit design requirements. This part is ROHS3 compliant and MSL Level 1, matching the compliance profile of the original AON6992. The AONY36352 supports continuous drain currents of 18.5A (Ta) and 49A (Tc), maintaining functional equivalence within the specified voltage and current operating envelope.

Both substitute parts are manufactured by Alpha & Omega Semiconductor Inc., share identical package geometry (8-DFN 5x6), maintain the dual N-channel asymmetrical configuration, and operate across the full -55°C to 150°C temperature range. Both parts carry REACH Unaffected and EAR99 ECCN classifications, consistent with the original AON6992.

Frequently Asked Questions (FAQ)

Q: Can the AONY36302 or AONY36352 be used as direct replacements for the AON6992 in existing PCB designs?

A: Yes, both AONY36302 and AONY36352 are mechanically and electrically compatible with the AON6992. All three parts utilize the 8-DFN (5x6) surface mount package with identical pin configuration and footprint. No PCB layout modifications are required for substitution.

Q: What is the difference between the AONY36302 and AONY36352?

A: The primary differences are packaging format and electrical specifications. The AONY36302 is supplied in standard packaging, while the AONY36352 is supplied in Tape & Reel format. The AONY36352 provides dual on-resistance and gate threshold voltage specifications, offering flexibility for different circuit operating conditions. The AONY36302 maintains single specifications matching the AON6992 profile more closely.

Q: Are there differences in gate charge between the AON6992 and the substitute parts?

A: Yes. The AON6992 specifies 13nC gate charge at 10V. The AONY36302 specifies 30nC, and the AONY36352 specifies 20nC and 52nC. Higher gate charge increases switching losses and may require gate driver adjustments in high-frequency applications. Circuit validation is necessary to confirm compatibility with existing gate drive circuitry.

Q: Do the substitute parts maintain the same input capacitance as the AON6992?

A: The AON6992 specifies 820pF input capacitance at 15V. The AONY36302 specifies 1000pF, representing a 22% increase. The AONY36352 specifies 820pF and 2555pF, with the higher value representing a significant increase. Input capacitance affects gate drive requirements and switching speed. Applications sensitive to capacitive loading require validation against substitute part specifications.

Q: Are all three parts RoHS compliant?

A: The AON6992 and AONY36352 are both ROHS3 compliant. The AONY36302 RoHS status is not specified in the provided data. Compliance verification with the AONY36302 manufacturer is required for applications with mandatory RoHS requirements.

Q: What is the moisture sensitivity level for each part?

A: The AON6992 and AONY36352 are both classified as MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions. The AONY36302 MSL classification is not specified in the provided data. Standard moisture control procedures are recommended for all surface mount components during storage and assembly.

Q: Can the AONY36352 be used in applications where Tape & Reel packaging is not required?

A: Yes. The AONY36352 is functionally equivalent to the AON6992 and AONY36302 regardless of packaging format. The Tape & Reel designation refers to the supply format, not the component itself. The actual device performance and pin configuration are identical to cut tape or bulk supply formats.

Q: How do the continuous drain current ratings compare between the three parts?

A: The AON6992 specifies 19A and 31A continuous drain current. The AONY36302 specifies 20A (Ta) and 51A (Tc), with additional ratings of 30A (Ta) and 85A (Tc). The AONY36352 specifies 18.5A (Ta) and 49A (Tc), with additional ratings of 30A (Ta) and 85A (Tc). All three parts meet or exceed the AON6992 current requirements. The (Ta) and (Tc) designations indicate ambient and case temperature conditions respectively.

Q: Are export control classifications identical across all three parts?

A: Yes. The AON6992, AONY36302, and AONY36352 all carry ECCN classification EAR99 and REACH Unaffected status, indicating identical export control and chemical compliance profiles.
