SMLJ6.5CA Equivalent & Substitute Parts

Part Overview

The SMLJ6.5CA is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 6.5V reverse standoff voltage, 11.2V maximum clamping voltage, and 267.9A peak pulse current capability in a DO-214AB (SMC) package. The part is Active status and ROHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical characteristics (voltage ratings, clamping specifications, peak pulse current) and mechanical compatibility (DO-214AB package, surface-mount configuration) within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMLJ6.5CA are grouped based on the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Voltage - Reverse Standoff: 6.5V
• Voltage - Clamping (Max) @ Ipp: 11.2V
• Voltage - Breakdown (Min): 7.22V (±0.02V tolerance acceptable)
• Package / Case: DO-214AB, SMC
• Bidirectional Channels: 1
• Type: Zener
• Mounting Type: Surface Mount

Secondary Consideration:

• Current - Peak Pulse (10/1000µs): 267.9A (full rating) or 134A (reduced rating)
• Power - Peak Pulse: 3000W (full rating) or 1500W (reduced rating)

Parts with identical voltage specifications and package configuration are direct substitutes. Parts with reduced peak pulse current and power ratings are functional substitutes for applications with lower transient energy requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Full Rating): SMDJ6.5CA and SMLJ6.5CA-TP are direct electrical and mechanical equivalents with identical voltage specifications, peak pulse current (267.9A), and power dissipation (3000W). Both are Active status and ROHS3 compliant. SMLJ6.5CA-TP offers extended operating temperature range (-55°C ~ 175°C) compared to the primary part (-55°C ~ 150°C).

Functional Substitutes (Reduced Rating): SMCJ6.5CA, SMCJ6.5CA-TP, and SMCJ6V5CA maintain identical voltage characteristics (6.5V standoff, 11.2V clamping) and package configuration but with reduced peak pulse current (134A or 133.9A) and power dissipation (1500W). These are suitable for applications with lower transient energy requirements. All three are Active status and ROHS3 compliant.

SMCJ6.5CA-TP provides the widest operating temperature range (-55°C ~ 175°C) among reduced-rating substitutes.

All substitute parts are Active status products with ROHS3 compliance, ensuring regulatory alignment with the primary part.

Frequently Asked Questions (FAQ)

Q: Can SMCJ6.5CA replace SMLJ6.5CA in all applications? A: SMCJ6.5CA is a functional substitute for applications where peak pulse current does not exceed 134A and peak pulse power does not exceed 1500W. The voltage specifications (6.5V standoff, 11.2V clamping) are identical. For applications requiring the full 267.9A peak pulse current and 3000W power dissipation, use SMDJ6.5CA or SMLJ6.5CA-TP instead.

Q: What is the difference between SMLJ6.5CA and SMLJ6.5CA-TP? A: Both parts are manufactured by Micro Commercial Co and share identical electrical specifications (6.5V standoff, 11.2V clamping, 267.9A peak pulse, 3000W power). SMLJ6.5CA-TP has an extended operating temperature range of -55°C ~ 175°C compared to -55°C ~ 150°C for the original SMLJ6.5CA. Packaging is Tape & Reel (TR) for both.

Q: Are all substitute parts in the same DO-214AB package? A: Yes. All listed substitute parts use the DO-214AB (SMC) package configuration, ensuring mechanical and footprint compatibility with the SMLJ6.5CA.

Q: Which substitute offers the best temperature performance? A: SMCJ6.5CA-TP and SMLJ6.5CA-TP both offer the extended operating temperature range of -55°C ~ 175°C. SMLJ6.5CA-TP maintains full electrical rating (267.9A, 3000W), while SMCJ6.5CA-TP has reduced rating (134A, 1500W).

Q: Are all parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and Active status, matching the regulatory compliance of the primary SMLJ6.5CA part.
