Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMDA12C.T is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 12V (Max)
• Voltage - Breakdown (Min): 13.3V
• Voltage - Clamping (Max) @ Ipp: 24V
• Current - Peak Pulse (10/1000µs): 12A (8/20µs)
• Power - Peak Pulse: 300W
• Capacitance @ Frequency: 120pF @ 1MHz
• Operating Temperature Range: -55°C ~ 125°C (TJ)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Bidirectional Channels: 4
• Type: Zener

The SMDA12C.TBT meets all electrical and mechanical specifications required for direct substitution. Packaging format differences (Cut Tape & Digi-Reel® versus standard packaging) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SMDA12C.TBT is the direct functional equivalent of the SMDA12C.T. Both components share identical electrical specifications and mechanical form factors. The primary distinction is product status: the SMDA12C.T is obsolete, while the SMDA12C.TBT maintains active production status.

The SMDA12C.TBT carries ROHS3 compliance, representing current regulatory alignment. Both parts maintain MSL Level 1 (Unlimited) moisture sensitivity classification and identical ECCN and HTSUS designations.

For new designs or production continuity requiring the SMDA12C.T specification, the SMDA12C.TBT provides equivalent electrical performance and mechanical compatibility with improved supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can SMDA12C.TBT be used as a direct replacement for SMDA12C.T?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including voltage ratings, current handling, temperature range, and package dimensions.

Q: What is the difference between SMDA12C.T and SMDA12C.TBT?

A: The primary differences are product status (obsolete versus active) and packaging format (standard versus Cut Tape & Digi-Reel®). Electrical specifications and mechanical compatibility are identical.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant. The SMDA12C.TBT carries ROHS3 certification, representing current regulatory standards. Both maintain identical MSL Level 1 classification and ECCN/HTSUS designations.

Q: Does the packaging format affect circuit performance?

A: No. Packaging format differences (Cut Tape & Digi-Reel® versus standard packaging) do not affect electrical performance or functional compatibility. The components are identical once mounted on the PCB.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: reverse standoff voltage (12V), breakdown voltage (13.3V), clamping voltage (24V), peak pulse current (12A), power rating (300W), capacitance (120pF @ 1MHz), operating temperature range (-55°C to 125°C), package type (8-SOIC), and channel configuration (4 bidirectional channels).
