SMCJ6.5C Equivalent & Substitute Parts Reference

Part Overview

The SMCJ6.5C is a 1500W bidirectional transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation. This surface mount component operates with a 6.5V reverse standoff voltage and 12.3V maximum clamping voltage, designed for general-purpose transient protection applications. The part is currently active in production and RoHS3 compliant.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and power dissipation rating. Substitutes must share identical or compatible package specifications and operating temperature ranges.

Engineering Selection Recommendations

SMCJ6.5C (Taiwan Semiconductor Corporation)

Primary selection for applications requiring the specified 12.3V clamping voltage. Active production status with 880 pieces in stock. RoHS3 and REACH compliant. Tape & Reel packaging suitable for automated assembly processes.

SMCJ6.5CA (EVVO Semi)

Qualified substitute with superior peak pulse current rating (134A vs. 128A) and lower clamping voltage (11.2V vs. 12.3V). Active production status with 38,100 pieces in stock. RoHS3 compliant with MSL Level 1 rating. Available in Cut Tape and Digi-Reel® packaging formats. The lower clamping voltage provides tighter transient suppression, suitable for sensitive circuit protection applications.

Both parts maintain identical reverse standoff voltage, breakdown voltage, peak pulse power, operating temperature range, and package configuration. Selection between these parts depends on circuit-specific clamping voltage requirements and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can SMCJ6.5CA replace SMCJ6.5C in existing designs?

A: Yes. Both parts share identical reverse standoff voltage (6.5V), breakdown voltage (7.22V), peak pulse power (1500W), operating temperature range (-55°C to 150°C), and package type (DO-214AB SMC). The SMCJ6.5CA has a lower clamping voltage (11.2V vs. 12.3V) and higher peak pulse current (134A vs. 128A), making it suitable for applications where tighter transient suppression is acceptable.

Q: What is the difference in clamping voltage between these parts?

A: SMCJ6.5C clamps at a maximum of 12.3V, while SMCJ6.5CA clamps at 11.2V. This 1.1V difference affects the peak voltage experienced by protected circuits during transient events. Circuit design must accommodate the substitute part's clamping characteristics.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SMCJ6.5C and SMCJ6.5CA are RoHS3 compliant and suitable for applications requiring environmental compliance certification.

Q: What packaging formats are available?

A: SMCJ6.5C is supplied in Tape & Reel (TR) format. SMCJ6.5CA is available in Cut Tape (CT) and Digi-Reel® formats. Packaging selection depends on assembly equipment compatibility and procurement requirements.

Q: Do both parts have identical operating temperature ranges?

A: Yes. Both parts operate across -55°C to 150°C junction temperature range, ensuring thermal compatibility in equivalent applications.

Q: What is the MSL rating for SMCJ6.5CA?

A: SMCJ6.5CA has MSL Level 1 (Unlimited), indicating no moisture sensitivity limitations during storage and handling.
