AOZ8000CI Equivalent & Substitute Parts

Part Overview

The AOZ8000CI is a steering transient voltage suppressor (TVS) diode manufactured by Alpha & Omega Semiconductor Inc., designed for power line protection in Ethernet applications. This part operates with a 5V reverse standoff voltage and 15V clamping voltage, housed in a SOT-23-6 surface mount package. The AOZ8000CI is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AOZ8000CI is determined by the following critical parameters:

Primary Substitution Criteria:

• Unidirectional channels: 4 (steering configuration)
• Package type: SOT-23-6 surface mount
• Voltage - Reverse Standoff: 5V nominal
• Voltage - Clamping: 15V maximum
• Current - Peak Pulse: 5A (8/20µs)
• Power - Peak Pulse: 60W
• Power line protection capability
• RoHS3 compliance

Substitute parts are grouped based on their ability to meet or exceed these electrical specifications while maintaining the same package footprint and mounting technology. Parts with active product status are prioritized over obsolete alternatives.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - AOZ8904CIL: AOZ8904CIL is the manufacturer-recommended substitute from Alpha & Omega Semiconductor Inc. with active product status. It maintains the same package footprint (SOT-23-6) and steering configuration with 4 unidirectional channels. The part operates within compatible voltage ranges (5.5V reverse standoff, 18V clamping) and supports power line protection. ROHS3 compliance is maintained. Peak pulse current is rated at 4A versus the original 5A, and peak pulse power is 50W versus 60W.

Secondary Substitutes - HDMIULC6-4SC6 and SZNUP4114HMR6T1G: HDMIULC6-4SC6 (STMicroelectronics) and SZNUP4114HMR6T1G (onsemi) are active alternatives with identical 4-channel steering configuration and SOT-23-6 packaging. HDMIULC6-4SC6 matches the original 5A peak pulse current specification. SZNUP4114HMR6T1G exceeds the original specification with 8A peak pulse current and includes AEC-Q101 automotive qualification. Both maintain ROHS3 compliance and power line protection capability.

Tertiary Substitutes - D5V0F4U6SO-7 and D1213A-04TS-7: D5V0F4U6SO-7 (Diodes Incorporated) provides a lower-current alternative (3A peak pulse) with 12V clamping voltage and extended operating temperature range (-65°C ~ 150°C). D1213A-04TS-7 (Diodes Incorporated) is rated for 1A peak pulse with 10V clamping and includes AEC-Q101 automotive qualification. Both are suitable for applications with reduced current requirements.

Limited Substitute - TPD4S009DBVR: TPD4S009DBVR (Texas Instruments) is an active part with 4-channel steering configuration and SOT-23-6 packaging. However, critical electrical parameters including clamping voltage and peak pulse current are not specified in available data. Peak pulse power is rated at 25W, significantly lower than the original 60W specification. Operating temperature range is limited to -40°C ~ 85°C.

Frequently Asked Questions (FAQ)

Q: Can AOZ8904CIL directly replace AOZ8000CI in existing designs? A: AOZ8904CIL is the manufacturer-recommended substitute and maintains the same SOT-23-6 package footprint and 4-channel steering configuration. However, the peak pulse current rating is 4A versus the original 5A, and peak pulse power is 50W versus 60W. Design verification is necessary if the application requires the full 5A specification.

Q: What is the difference between SOT-23-6 and TSOT-23-6 packages? A: TSOT-23-6 is a thin variant of the SOT-23-6 package. Both maintain the same pin configuration and footprint compatibility. Parts specified as SOT-23-6 Thin or TSOT-23-6 are mechanically compatible with standard SOT-23-6 designs.

Q: Why does SZNUP4114HMR6T1G have higher peak pulse current (8A) than the original part? A: SZNUP4114HMR6T1G is rated for 8A peak pulse current at 8/20µs, exceeding the original 5A specification. This part can be used as a direct substitute with improved transient protection capability. The higher current rating does not create compatibility issues in applications designed for the original 5A specification.

Q: Are all substitute parts RoHS3 compliant? A: All substitute parts listed are ROHS3 compliant, matching the compliance status of the original AOZ8000CI.

Q: Which substitute part is recommended for automotive applications? A: D1213A-04TS-7 and SZNUP4114HMR6T1G both carry AEC-Q101 automotive qualification. SZNUP4114HMR6T1G is the preferred automotive alternative due to its higher peak pulse current rating (8A) and extended operating temperature range support.

Q: What is the impact of different clamping voltage ratings on substitution? A: Clamping voltage determines the maximum voltage level during transient suppression. The original AOZ8000CI clamps at 15V maximum. Substitutes with lower clamping voltages (10V to 12V) provide tighter voltage regulation but may not be suitable for applications requiring the full 15V clamping specification. Substitutes with higher clamping voltages (17V to 18V) provide more relaxed clamping and are generally compatible with the original design.

Q: Can TPD4S009DBVR be used as a substitute if electrical parameters are not fully specified? A: TPD4S009DBVR has incomplete electrical parameter data in available documentation. The unspecified clamping voltage and peak pulse current make it unsuitable for direct substitution without additional verification and testing against the original AOZ8000CI specifications.
