SMDA12CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMDA12CE3/TR13 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, classified within the TVSarray™ series. This surface-mount component operates as a Zener-type TVS diode with four bidirectional channels, designed for general-purpose transient voltage suppression applications. The device is currently in active production status and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring 12V reverse standoff voltage protection with 19V maximum clamping voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMDA12CE3/TR13 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 12V
• Voltage - Breakdown (Min): 13.3V
• Voltage - Clamping (Max) @ Ipp: 19V
• Current - Peak Pulse (10/1000µs): 5A (8/20µs)
• Power - Peak Pulse: 300W
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Bidirectional Channels: 4
• Type: Zener

Direct Equivalents maintain identical electrical specifications and are sourced from the same manufacturer (Microchip Technology). These parts differ only in packaging configuration (Tape & Reel variant designation) and are fully interchangeable at the circuit level.

Similar Substitutes share the same reverse standoff voltage, breakdown voltage, and package form factor but exhibit variations in clamping voltage, peak pulse current, or capacitance characteristics. These parts require circuit-level evaluation to confirm suitability for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (SMDB12C/TR7 and SMDB12CE3/TR7):

The SMDB12C/TR7 and SMDB12CE3/TR7 are direct electrical and mechanical equivalents to the SMDA12CE3/TR13. Both parts are manufactured by Microchip Technology, maintain active product status, and satisfy identical electrical specifications across all critical parameters including reverse standoff voltage, breakdown voltage, clamping voltage, and peak pulse current. Both parts carry ROHS3 compliance, REACH Unaffected status, and unlimited moisture sensitivity rating (MSL 1). These parts are suitable for direct substitution in applications where the SMDA12CE3/TR13 is specified, with no circuit-level modifications required. Selection between these direct equivalents may be based on packaging availability, lead time, or inventory considerations.

Similar Substitute (SMDA12C.TBT):

The SMDA12C.TBT, manufactured by Semtech Corporation, shares the same reverse standoff voltage (12V), breakdown voltage (13.3V), and package form factor (8-SOIC) as the main part. However, this substitute exhibits higher clamping voltage (24V versus 19V), increased peak pulse current capability (12A versus 5A), and higher capacitance (120pF versus 95pF). The operating temperature range is also reduced to -55°C to 125°C compared to the main part's -55°C to 150°C range. The SMDA12C.TBT maintains ROHS3 compliance, REACH Unaffected status, and MSL 1 rating. This part is classified as a similar substitute and requires application-specific evaluation to confirm compatibility with circuit requirements, particularly regarding clamping voltage tolerance and temperature operating range.

Frequently Asked Questions (FAQ)

Q: Can SMDB12C/TR7 be used as a direct replacement for SMDA12CE3/TR13?

A: Yes. The SMDB12C/TR7 is a direct equivalent. Both parts share identical electrical specifications (12V reverse standoff, 13.3V breakdown, 19V clamping, 5A peak pulse current), the same 8-SOIC package form factor, and equivalent compliance certifications (ROHS3, REACH Unaffected, MSL 1). No circuit modifications are required.

Q: What is the difference between SMDB12C/TR7 and SMDB12CE3/TR7?

A: Both parts are direct equivalents with identical electrical and mechanical specifications. The difference lies in packaging designation within the Tape & Reel (TR) configuration. Both are suitable for direct substitution with the SMDA12CE3/TR13.

Q: Is SMDA12C.TBT a direct replacement for SMDA12CE3/TR13?

A: No. SMDA12C.TBT is classified as a similar substitute, not a direct equivalent. While it maintains the same 12V reverse standoff voltage and 8-SOIC package, it exhibits higher clamping voltage (24V versus 19V), higher peak pulse current (12A versus 5A), and higher capacitance (120pF versus 95pF). The maximum operating temperature is also lower (125°C versus 150°C). Application-specific evaluation is required to confirm compatibility.

Q: Are all substitute parts available in the same packaging format?

A: No. The SMDA12CE3/TR13 is supplied in Tape & Reel (TR) packaging. The direct equivalents SMDB12C/TR7 and SMDB12CE3/TR7 are also supplied in Tape & Reel format. The similar substitute SMDA12C.TBT is supplied in Cut Tape (CT) and Digi-Reel® packaging. Packaging format differences do not affect electrical compatibility but may impact procurement and assembly processes.

Q: What compliance certifications apply to all listed parts?

A: All parts listed (main part and substitutes) maintain ROHS3 compliance, REACH Unaffected status, and unlimited moisture sensitivity rating (MSL 1). All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Can SMDA12C.TBT be used in applications requiring the exact 19V clamping voltage specification?

A: No. The SMDA12C.TBT exhibits a maximum clamping voltage of 24V, which exceeds the 19V specification of the SMDA12CE3/TR13. Applications with strict clamping voltage requirements must use direct equivalents (SMDB12C/TR7 or SMDB12CE3/TR7) to maintain circuit performance specifications.

Q: What is the significance of the "CE3" designation in SMDA12CE3/TR13?

A: The "CE3" designation is part of the manufacturer's part numbering scheme. Direct equivalents may use different designations (such as "C" in SMDB12C/TR7) while maintaining identical electrical specifications. The base product number (SMDA12 or SMDB12) and electrical parameters are the primary indicators of substitution eligibility.
