Key Parameters

Substitute Part Grouping Explanation

Substitution of the AOZ8000CIL_3 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff: 5.5V (Max)
• Voltage - Breakdown (Min): 6.6V
• Package / Case: SOT-23-6 (identical physical footprint)
• Type: Steering (Rail to Rail) with 4 Unidirectional Channels
• Mounting Type: Surface Mount

Application-Specific Considerations:

• Power Line Protection capability
• Operating Temperature Range compatibility
• Capacitance characteristics at 1MHz

The AOZ8904CIL qualifies as a substitute part based on matching the core voltage standoff, breakdown voltage, package type, steering configuration, and power line protection designation. Differences in clamping voltage, peak pulse current, and power dissipation must be evaluated against specific circuit requirements.

Engineering Selection Recommendations

AOZ8904CIL Substitution Assessment:

The AOZ8904CIL is an active product from Alpha & Omega Semiconductor Inc. with identical package geometry (SOT-23-6) and matching core voltage parameters (5.5V standoff, 6.6V breakdown). Both components maintain REACH Unaffected compliance status and MSL Level 1 moisture sensitivity rating.

The primary distinction between the main part and substitute lies in current handling capacity and clamping voltage specification. The AOZ8000CIL_3 supports 12A peak pulse current with 15V clamping, while the AOZ8904CIL is rated for 4A peak pulse current with 18V typical clamping. The AOZ8904CIL operates across a narrower temperature range (-40°C to 125°C versus -55°C to 125°C).

Selection of the AOZ8904CIL as a substitute is appropriate for applications where the lower peak pulse current specification and higher clamping voltage are compatible with circuit design parameters. The active product status of the AOZ8904CIL provides superior long-term supply chain availability compared to the obsolete AOZ8000CIL_3.

Frequently Asked Questions (FAQ)

Q: Can the AOZ8904CIL directly replace the AOZ8000CIL_3 in existing designs?

A: Direct replacement is possible only if the circuit design accommodates the AOZ8904CIL's lower peak pulse current rating (4A versus 12A) and higher clamping voltage (18V typical versus 15V maximum). The identical SOT-23-6 package and matching voltage standoff/breakdown parameters enable physical and electrical compatibility at the package level. Circuit-level validation is required to confirm functional equivalence.

Q: What are the key differences in electrical performance?

A: The AOZ8000CIL_3 provides higher peak pulse current capacity (12A at 10/1000µs) and lower clamping voltage (15V maximum), while the AOZ8904CIL offers lower peak pulse current (4A at 8/20µs) and higher clamping voltage (18V typical). Both devices maintain identical reverse standoff voltage (5.5V) and breakdown voltage (6.6V minimum). Pulse waveform specifications differ between the two parts.

Q: Are there temperature range considerations for substitution?

A: The AOZ8000CIL_3 operates from -55°C to 125°C junction temperature, while the AOZ8904CIL operates from -40°C to 125°C. Applications requiring operation below -40°C junction temperature cannot use the AOZ8904CIL as a substitute. Applications within the -40°C to 125°C range are compatible with both devices.

Q: How do capacitance differences affect circuit performance?

A: The AOZ8000CIL_3 exhibits 1.85pF capacitance at 1MHz, while the AOZ8904CIL exhibits 1.25pF at the same frequency. This 0.6pF difference may influence high-frequency signal integrity in sensitive applications. Circuits with stringent capacitance requirements should evaluate this parameter against design specifications.

Q: What is the significance of the product status difference?

A: The AOZ8000CIL_3 carries Obsolete status, indicating discontinued manufacturing and limited future availability. The AOZ8904CIL maintains Active status, ensuring ongoing production, established supply chains, and manufacturer support. For new designs or long-term production requirements, the active AOZ8904CIL is the preferred selection.

Q: Are packaging and moisture sensitivity identical?

A: Both the AOZ8000CIL_3 and AOZ8904CIL utilize SOT-23-6 surface mount packages with MSL Level 1 (Unlimited) moisture sensitivity rating. Packaging dimensions, lead configuration, and moisture handling requirements are identical. The AOZ8904CIL is supplied in Tape & Reel format, while the AOZ8000CIL_3 packaging format is not specified in available data.
