SMCJ110CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMCJ110CE3/TR13 is an active-status Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology. This bidirectional Zener-type component operates in the 110V reverse standoff category with surface mount packaging (DO-214AB/SMC). The device provides transient voltage protection for general-purpose applications across an operating temperature range of -65°C to 150°C.

Identification of equivalent and substitute parts is necessary when primary inventory availability is limited, when sourcing from multiple qualified suppliers is required, or when design specifications permit variations within established electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution criteria for the SMCJ110CE3/TR13 are based on the following electrical and mechanical parameters:

• Voltage Class Matching: Reverse standoff voltage of 110V and breakdown voltage minimum of 122V are mandatory alignment criteria
• Package Compatibility: All substitute parts must use DO-214AB (SMC) surface mount packaging to ensure PCB footprint compatibility
• Clamping Voltage Range: Acceptable clamping voltage range is 177V to 196V @ Ipp
• Current Handling: Peak pulse current capacity ranges from 7.7A to 28.3A depending on power dissipation requirements
• Power Dissipation: Peak pulse power from 1500W to 5000W
• Temperature Range: Operating temperature minimum of -55°C to -65°C with 150°C maximum
• Compliance: RoHS3 compliance and MSL Level 1 certification

Parts meeting these electrical parameters within their respective manufacturer specifications are classified as functional equivalents or substitutes.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts carry active product status from their respective manufacturers and maintain ROHS3 compliance. Selection between equivalent options should be based on:

Clamping Voltage Performance: The SMCJ110CE3/TR13 specifies 196V clamping voltage. Substitute parts with 177V clamping voltage provide reduced voltage protection margin during transient events. Selection of 196V-rated alternatives provides specification alignment.

Thermal Performance: Operating temperature range extends to -65°C in the SMCJ110CE3/TR13 compared to -55°C minimum in all substitute options. Applications requiring full -65°C to 150°C coverage require the primary part or equivalent with matching lower temperature limit.

Power Dissipation Capability: Substitute options range from 1500W (equivalent) to 5000W (enhanced). Power rating selection must align with application transient energy requirements. The 5.0SMDJ110CA rated at 5000W offers enhanced protection headroom for high-energy transient events.

Compliance and Moisture Sensitivity: All options maintain RoHS3 certification and MSL Level 1 rating (unlimited shelf life), ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts pin-for-pin compatible with the SMCJ110CE3/TR13? A: All substitute parts use DO-214AB (SMC) surface mount packaging with identical pinout and footprint geometry. Mechanical compatibility is confirmed across all listed options.

Q: What is the significance of the voltage clamping difference (196V vs. 177V)? A: Clamping voltage determines the maximum voltage to which the TVS diode limits transient overvoltages. The 196V specification on the SMCJ110CE3/TR13 provides 19V additional protection margin compared to 177V alternatives. Applications sensitive to voltage transient amplitude must account for this 10.7% difference in clamping performance.

Q: Can SMDJ110CA be used as a substitute when higher peak pulse current capacity is required? A: Yes. The SMDJ110CA provides 17A peak pulse current compared to 7.7A on the SMCJ110CE3/TR13, with 3000W power dissipation. This option suits applications where higher transient current absorption is necessary within the 110V voltage class.

Q: What does RoHS3 compliance indicate for component selection? A: RoHS3 compliance certifies that the component does not contain restricted substances as defined by the Restriction of Hazardous Substances Directive. All listed options meet this standard, ensuring compatibility with regulatory requirements for electronics manufacturing in target markets.

Q: Is the -55°C minimum operating temperature of substitutes acceptable for -65°C applications? A: No. Applications specifying -65°C operation require the SMCJ110CE3/TR13 or an equivalent part with confirmed -65°C minimum rating. Substitute parts with -55°C minimum are unsuitable for extended low-temperature operation without additional thermal analysis.

Q: What does MSL Level 1 certification mean? A: Moisture Sensitivity Level (MSL) 1 indicates the component has unlimited shelf life when stored in standard conditions. No moisture bake-out is required prior to assembly, simplifying inventory management and reducing process complexity.
