Equivalent & Substitute Parts for SMDA05CE3/TR13

Part Overview

The SMDA05CE3/TR13 is a Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional 4-channel TVS array operates with a 5V reverse standoff voltage, 11V maximum clamping voltage, and 5A peak pulse current, housed in an 8-SOIC package. The part is Active in product status and RoHS3 compliant. Alternative models are necessary to accommodate supply chain variations, different packaging formats (Tape & Reel versus Cut Tape), or sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity is determined by matching the following critical parameters: Voltage - Reverse Standoff, Voltage - Breakdown, Voltage - Clamping, package type (8-SOIC), bidirectional channel count (4), and operating temperature range. Current - Peak Pulse and Capacitance are evaluated as compatible specifications; parts with equal or higher peak pulse current and comparable capacitance values are functionally equivalent. Packaging format differences (Tape & Reel versus Cut Tape) do not affect electrical substitutability but represent logistical variations.

Critical Parameters for Substitution:

• Voltage - Reverse Standoff: 5V
• Voltage - Breakdown: 6V minimum
• Voltage - Clamping: 11V maximum
• Package: 8-SOIC
• Bidirectional Channels: 4
• Operating Temperature: -55°C minimum, 150°C maximum

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and RoHS3 compliance, ensuring suitability for industrial and commercial applications. The Microchip Technology variants (SMDA05C-4-2E3/TR7, SMDA05C/TR7, SMDB05CE3/TR7) are electrically identical to the main part and differ only in packaging format or part designation. Higher inventory availability of these alternatives (1813, 853, and 1823 units respectively) may support procurement timelines.

The Semtech Corporation variant SMDA05C.TBT meets all critical voltage specifications and maintains RoHS3 compliance. This part features enhanced current handling capability (17A peak pulse) and identical power dissipation, making it suitable for applications requiring greater transient current margin. The operating temperature maximum of 125°C (versus 150°C for Microchip variants) should be evaluated against application thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can SMDA05C-4-2E3/TR7 directly replace SMDA05CE3/TR13? A: Yes. Both parts are manufactured by Microchip Technology and share identical electrical parameters: 5V standoff, 6V minimum breakdown, 11V clamping, and 5A peak pulse current. The difference lies in part designation and packaging format (Tape & Reel for both). Direct substitution is supported without circuit modification.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape provides components on tape segments, typically used for lower-volume or manual assembly operations. Electrically, both formats contain identical components.

Q: Is SMDA05C/TR7 compatible with SMDA05CE3/TR13? A: Yes. Both parts feature identical electrical specifications and mounting type (Surface Mount, 8-SOIC package). The primary difference is packaging format: SMDA05C/TR7 uses Cut Tape rather than Tape & Reel.

Q: How does SMDA05C.TBT differ from the main part? A: SMDA05C.TBT is manufactured by Semtech Corporation and delivers higher peak pulse current (17A versus 5A). Voltage specifications remain identical. The maximum operating temperature is 125°C compared to 150°C for Microchip variants. This part is suitable for applications requiring greater transient current capacity within the specified voltage range.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed parts, including the main part SMDA05CE3/TR13, carry RoHS3 Compliant certification and are suitable for applications requiring restricted substance compliance.

Q: What package considerations apply when selecting between these parts? A: All parts use the 8-SOIC package with 0.154" width (3.90mm). PCB footprints and land patterns are identical across all variants. Selection should focus on packaging format (Tape & Reel for automated assembly, Cut Tape for lower-volume assembly) and supply chain availability.
