SMCJ200C Equivalent & Substitute Parts

Part Overview

The SMCJ200C is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 200V reverse standoff voltage rating and 1500W peak pulse power handling capability in a surface-mount DO-214AB package. The SMCJ200C is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMCJ200C is determined by strict equivalence across the following electrical and mechanical parameters:

• Reverse standoff voltage: 200V (Typ)
• Peak pulse current rating: 4.6A
• Peak pulse power rating: 1500W
• Package type: DO-214AB (SMC)
• Mounting configuration: Surface mount
• Bidirectional channel count: 1
• Operating temperature range: -55°C to 150°C

The SMCJ200CA from Good-Ark Semiconductor meets all these criteria. While minor variations exist in breakdown voltage (224V minimum vs. 211.95V minimum) and clamping voltage (324V maximum vs. 340.2V maximum), these remain within the functional tolerance band for general-purpose TVS applications and do not preclude direct substitution in circuits designed for the SMCJ200C.

Parameter Comparison

Engineering Selection Recommendations

The SMCJ200CA is a direct functional equivalent for the obsolete SMCJ200C. Both components are ROHS3 compliant and carry MSL Level 1 moisture sensitivity ratings, ensuring compatibility with standard PCB assembly and storage protocols. The SMCJ200CA maintains active product status with Good-Ark Semiconductor, providing supply continuity and long-term availability advantages over the obsolete SMCJ200C. Electrical parameter alignment across all critical specifications—reverse standoff voltage, peak pulse current, peak pulse power, and operating temperature range—supports seamless integration into existing circuit designs without modification.

Frequently Asked Questions (FAQ)

Q: Can the SMCJ200CA directly replace the SMCJ200C without circuit modification?

A: Yes. Both components share identical reverse standoff voltage (200V), peak pulse current (4.6A), peak pulse power (1500W), package type (DO-214AB), and operating temperature range (-55°C to 150°C). Direct substitution is supported.

Q: What are the differences in breakdown and clamping voltages between these parts?

A: The SMCJ200CA exhibits a higher minimum breakdown voltage (224V vs. 211.95V) and slightly lower maximum clamping voltage (324V vs. 340.2V). These variations remain within acceptable tolerance for general-purpose transient suppression and do not affect functional compatibility.

Q: Are both parts available in the same packaging options?

A: Both the SMCJ200C and SMCJ200CA are supplied in DO-214AB (SMC) surface-mount packages. The SMCJ200CA is available in Cut Tape (CT) and Digi-Reel packaging, as well as Tape & Reel (TR) configurations, providing flexible procurement options.

Q: What is the product status difference, and why does it matter?

A: The SMCJ200C is classified as obsolete, while the SMCJ200CA is active. Active status ensures ongoing manufacturing, quality control, and supply availability. For new designs or long-term production requirements, the SMCJ200CA is the recommended selection.

Q: Are both parts RoHS and REACH compliant?

A: Both components are ROHS3 compliant. The SMCJ200CA carries REACH Unaffected status. Both meet environmental and regulatory requirements for industrial and commercial applications.
