Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMDA05CE3/TR7 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Voltage - Reverse Standoff: 5V (Typ)
• Voltage - Breakdown (Min): 6V
• Voltage - Clamping (Max) @ Ipp: 11V
• Current - Peak Pulse (8/20µs): minimum 5A
• Power - Peak Pulse: minimum 300W
• Bidirectional Channels: 4

Mechanical & Environmental Requirements:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C (TJ) minimum
• RoHS3 Compliance: Required
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Packaging Format:

• Tape & Reel (TR) or Cut Tape (CT) formats are interchangeable for component-level substitution

Parts meeting all electrical parameters within specified tolerances and maintaining identical mechanical form factor and environmental ratings are classified as direct substitutes. Parts with superior electrical performance (higher current or power ratings) are classified as compatible upgrades.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Microchip Technology):

SMDA05C-4-2E3/TR7, SMDA05C/TR7, and SMDB05CE3/TR7 are direct electrical and mechanical equivalents to SMDA05CE3/TR7. All three parts maintain identical voltage ratings, current specifications, and thermal operating ranges. Selection among these Microchip variants is determined by packaging format availability: Tape & Reel (TR) for automated assembly or Cut Tape (CT) for manual placement. All three maintain Active product status with full RoHS3 compliance and REACH unaffected designation.

Compatible Upgrade (Semtech Corporation):

SMDA05C.TBT from Semtech Corporation is a compatible upgrade option. This part exceeds the electrical performance of the primary part with a 17A peak pulse current rating (versus 5A), while maintaining identical voltage clamping characteristics and 300W peak pulse power rating. The SMDA05C.TBT operates within a reduced temperature range (-55°C to 125°C versus -55°C to 150°C) and exhibits higher capacitance (350pF versus 200pF at 1MHz). This part is suitable for applications requiring enhanced transient current handling capacity within the specified temperature envelope. RoHS3 compliance and REACH unaffected status are maintained.

Compliance & Certification:

All substitute parts listed maintain RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited). No additional qualification or testing documentation is required for direct substitution within the same electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can SMDA05C-4-2E3/TR7 be used as a direct replacement for SMDA05CE3/TR7?

A: Yes. SMDA05C-4-2E3/TR7 is a direct electrical and mechanical equivalent. Both parts share identical voltage ratings (5V reverse standoff, 11V clamping), current specifications (5A peak pulse), and thermal operating range (-55°C to 150°C). The primary difference is packaging format (Tape & Reel). Both maintain Active product status and full RoHS3 compliance.

Q: What is the difference between SMDA05C/TR7 and SMDA05CE3/TR7?

A: SMDA05C/TR7 is supplied in Cut Tape (CT) format, while SMDA05CE3/TR7 is supplied in Tape & Reel (TR) format. All electrical and mechanical specifications are identical. Selection depends on assembly process requirements: Tape & Reel for high-volume automated assembly, Cut Tape for lower-volume or manual placement operations.

Q: Is SMDB05CE3/TR7 compatible with SMDA05CE3/TR7?

A: Yes. SMDB05CE3/TR7 is a direct substitute. Both parts are manufactured by Microchip Technology and share identical electrical specifications, voltage ratings, current handling, and thermal operating range. The base product number differs (SMDB05 versus SMDA05), but functional performance is equivalent.

Q: Can SMDA05C.TBT from Semtech replace SMDA05CE3/TR7?

A: SMDA05C.TBT is a compatible upgrade. It maintains identical voltage clamping characteristics (5V standoff, 11V clamp) but provides enhanced current handling (17A versus 5A peak pulse). The operating temperature range is reduced to -55°C to 125°C (versus -55°C to 150°C). This part is suitable for applications requiring higher transient current capacity within the specified temperature limits.

Q: Are there any compliance or certification differences between these substitute parts?

A: No. All substitute parts listed maintain identical RoHS3 compliance status, REACH unaffected designation, and Moisture Sensitivity Level 1 (Unlimited). No additional qualification documentation is required for direct substitution.

Q: What packaging formats are available for these TVS diodes?

A: Microchip Technology supplies SMDA05CE3/TR7, SMDA05C-4-2E3/TR7, and SMDB05CE3/TR7 in Tape & Reel (TR) format for automated assembly. SMDA05C/TR7 is available in Cut Tape (CT) format for manual placement. Semtech SMDA05C.TBT is supplied in Tape & Reel (TR) format. All use identical 8-SOIC (0.154", 3.90mm Width) mechanical packaging.

Q: How do I select between multiple substitute options?

A: Selection criteria are: (1) Manufacturer preference and supply chain strategy; (2) Packaging format requirement (Tape & Reel for automated lines, Cut Tape for manual assembly); (3) Current handling requirement (standard 5A or upgraded 17A); (4) Operating temperature requirement (150°C maximum for Microchip, 125°C maximum for Semtech). All parts meet identical electrical specifications for 5V standoff and 11V clamping voltage applications.
