Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP22804BSN-7 is determined by strict equivalence across the following critical parameters:

• Switch Type: USB Switch
• Output Type: P-Channel with 1:1 ratio
• Current Rating: 2.5A maximum output
• Voltage Range: 2.7V ~ 5.5V load voltage
• On-Resistance: 50mOhm typical
• Package: 6-UDFN Exposed Pad (U-DFN2020-6)
• Fault Protection: Current Limiting (Fixed), Over Temperature, UVLO
• Features: Load Discharge, Status Flag
• Operating Temperature: -40°C ~ 85°C

The AP22804ASN-7 meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, mechanical packaging, and functional features, making them directly interchangeable in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the AP22804BSN-7 and AP22804ASN-7 are active production components from Diodes Incorporated with identical ROHS3 compliance and REACH unaffected status. Selection between these parts is based on inventory availability and supply chain considerations rather than technical differentiation. Both parts carry MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special storage or handling requirements beyond standard ESD precautions.

For applications requiring USB power switching with 2.5A maximum output current in the 2.7V to 5.5V range, either part number provides equivalent performance and reliability. PCB layout and thermal management considerations remain consistent across both variants due to identical package geometry and electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can AP22804ASN-7 be used as a direct replacement for AP22804BSN-7?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output current ratings, voltage ranges, on-resistance characteristics, and package dimensions. No circuit modifications are required for substitution.

Q: Are there any differences in fault protection between these parts?

A: No. Both parts implement identical fault protection mechanisms: fixed current limiting, over-temperature protection, and UVLO (Under-Voltage Lock-Out).

Q: Do these parts require different PCB layouts or thermal management?

A: No. Both parts use the 6-UDFN Exposed Pad package (U-DFN2020-6) with identical mechanical dimensions and thermal characteristics. PCB layout and thermal design remain unchanged.

Q: What is the significance of the different suffix letters (BSN vs ASN)?

A: The suffix designates different manufacturing batches or tape reel configurations from Diodes Incorporated. The electrical and functional specifications remain identical.

Q: Are both parts suitable for USB power switching applications?

A: Yes. Both parts are classified as USB switches with identical 1:1 high-side P-Channel configuration, making them suitable for USB power delivery and load switching applications within the specified voltage and current ranges.

Q: What is the moisture sensitivity classification for these parts?

A: Both parts carry MSL Level 1 (Unlimited), indicating no moisture-related storage or handling restrictions beyond standard ESD protection practices.
