TPD4S009DBVRG4 Equivalent & Substitute Parts

Part Overview

The TPD4S009DBVRG4 is a steering transient voltage suppressor (TVS) diode manufactured by Texas Instruments, designed for multi-channel rail-to-rail protection in high-speed interfaces. This component provides transient voltage suppression for Ethernet and HDMI applications with a 5.5V reverse standoff voltage and 25W peak pulse power rating. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPD4S009DBVRG4 is determined by the following critical parameters:

Primary Substitution Criteria:

• Steering (Rail to Rail) TVS diode topology
• 4 unidirectional channels
• 5.5V reverse standoff voltage rating
• Surface mount package compatibility
• ROHS3 compliance and MSL 1 rating

Substitute Parts Identified:

Group 1 - Direct Manufacturer Equivalent (Recommended): TPD4S009DBVR from Texas Instruments maintains identical electrical specifications and package footprint (SOT-23-6). The only difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel), with active product status ensuring long-term availability.

Group 2 - Functional Equivalent with Package Variation: IP4220CZ6,125 from Nexperia USA Inc. provides equivalent steering TVS functionality with 4 channels and 5.5V standoff voltage. Package designation differs (6-TSOP/SC-74 versus SOT-23-6), requiring PCB footprint verification before implementation.

Group 3 - Partial Specification Match: D1213A-04TS-7 from Diodes Incorporated is a steering TVS with 4 channels but operates at 3.3V reverse standoff voltage with extended temperature range (-65°C ~ 150°C) and automotive qualification (AEC-Q101). This part is suitable only for applications with lower voltage requirements.

Parameter Comparison

Engineering Selection Recommendations

First Priority - TPD4S009DBVR: This Texas Instruments part is the recommended substitute. It maintains identical electrical specifications (5.5V standoff, 9V breakdown, 25W peak pulse) and package footprint (SOT-23-6) as the discontinued TPD4S009DBVRG4. The only difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). Active product status ensures availability for production and future orders. No PCB redesign is required.

Second Priority - IP4220CZ6,125: This Nexperia part provides equivalent steering TVS functionality with matching 5.5V standoff voltage and 4-channel configuration. However, the package designation (6-TSOP/SC-74) differs from the original SOT-23-6, requiring PCB footprint verification and potential layout modifications. Use this option only if PCB redesign is acceptable and the alternative package footprint is compatible with your design.

Third Priority - D1213A-04TS-7: This Diodes Incorporated part operates at 3.3V reverse standoff voltage, which is lower than the original 5.5V specification. It is suitable only for applications with reduced voltage requirements. The extended temperature range (-65°C ~ 150°C) and automotive qualification (AEC-Q101) make this part appropriate for automotive or high-temperature environments where the lower voltage rating is acceptable.

Frequently Asked Questions (FAQ)

Q: Can TPD4S009DBVR be used as a direct replacement for TPD4S009DBVRG4?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications (5.5V reverse standoff, 9V breakdown, 25W peak pulse) and the same SOT-23-6 package footprint. The difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). No PCB modifications are required.

Q: What is the key difference between the TPD4S009DBVRG4 and IP4220CZ6,125?

A: Both are 4-channel steering TVS diodes with 5.5V standoff voltage. The primary difference is the package: TPD4S009DBVRG4 uses SOT-23-6, while IP4220CZ6,125 uses 6-TSOP (SC-74). PCB footprint compatibility must be verified before substitution.

Q: Why is D1213A-04TS-7 listed as a substitute if it has a different voltage rating?

A: D1213A-04TS-7 operates at 3.3V reverse standoff voltage, which is lower than the original 5.5V. It is included as a substitute only for applications where the lower voltage rating is acceptable. It is not suitable for circuits designed for 5.5V protection levels.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (TPD4S009DBVR, IP4220CZ6,125, and D1213A-04TS-7) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's compliance status.

Q: Which substitute part has the best long-term availability?

A: TPD4S009DBVR from Texas Instruments is the recommended choice for long-term availability. It maintains active product status and is manufactured by the same company as the original part, ensuring consistent supply and support.

Q: Can D1213A-04TS-7 be used in Ethernet and HDMI applications?

A: D1213A-04TS-7 is rated for general power line protection applications. Its 3.3V standoff voltage is below the typical requirements for Ethernet and HDMI interfaces, which typically operate at 5V or higher. Use this part only if your specific application operates at 3.3V signal levels.
