Engineering Selection Recommendations

AONS36308 Selection Criteria: This part is suitable for applications requiring active product status with confirmed long-term availability. The AONS36308 provides 26A continuous drain current at 25°C (Ta) with 6.1mOhm maximum on-resistance, maintaining electrical performance within the 30V operating envelope. Active product status and ROHS3 compliance ensure regulatory alignment and supply chain continuity.

AONS36306 Selection Criteria: This part is suitable for applications requiring enhanced current handling capability. The AONS36306 provides 28A continuous drain current at 25°C (Ta) with 5.2mOhm maximum on-resistance, offering improved performance characteristics over the AONS36308. Active product status, higher inventory availability (7955 units), and ROHS3 compliance support long-term design implementation.

Compliance and Regulatory Alignment: Both substitute parts maintain identical regulatory certifications to the original AONS36354: ROHS3 compliance, MSL 1 rating, REACH unaffected status, EAR99 ECCN classification, and 8541.29.0095 HTSUS code. These certifications ensure direct substitution without regulatory or supply chain complications.

Inventory and Procurement: AONS36308 maintains 4068 units in stock; AONS36306 maintains 7955 units in stock. Both parts are available in Tape & Reel packaging format, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can AONS36308 and AONS36306 be used interchangeably with AONS36354?

A: Both parts share the same 30V Vdss rating, N-Channel MOSFET technology, and 5x6 DFN package footprint. Electrical and mechanical compatibility is established through these common parameters. Selection between AONS36308 and AONS36306 depends on specific current and on-resistance requirements of the application circuit.

Q: What are the key differences between AONS36308 and AONS36306?

A: The primary differences are continuous drain current ratings and on-resistance specifications. AONS36308 provides 26A (Ta) / 53A (Tc) with 6.1mOhm on-resistance. AONS36306 provides 28A (Ta) / 63A (Tc) with 5.2mOhm on-resistance. Both maintain identical voltage ratings, gate charge, input capacitance, and thermal operating range.

Q: Are package dimensions identical across all three parts?

A: All three parts utilize 5x6 DFN surface mount packages. AONS36308 uses 8-DFN-EP (enhanced power) configuration; AONS36306 uses standard 8-DFN configuration. Both maintain mechanical compatibility with PCB layouts designed for the original AONS36354.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. AONS36308 and AONS36306 both maintain ROHS3 compliance, MSL 1 rating, REACH unaffected status, EAR99 ECCN classification, and 8541.29.0095 HTSUS code, identical to the original AONS36354.

Q: What is the significance of the base product number AONS363?

A: The shared base product number AONS363 indicates that AONS36354, AONS36308, and AONS36306 are part of the same product family from Alpha & Omega Semiconductor Inc., confirming functional and electrical relationship across the three part numbers.

Q: How do gate charge and input capacitance specifications affect circuit design?

A: Both substitute parts maintain identical gate charge (30 nC @ 10V) and input capacitance (1000 pF @ 15V) specifications. These parameters determine gate drive circuit requirements and switching speed characteristics. Identical specifications ensure that existing gate drive designs require no modification.

Q: What inventory considerations apply to part selection?

A: AONS36306 maintains higher inventory availability (7955 units) compared to AONS36308 (4068 units). For applications requiring extended production runs or long-term supply assurance, AONS36306 provides greater procurement flexibility.
