Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214L-T6.5CALF is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Breakdown (Min): 7.22V (±tolerance)
• Voltage - Clamping (Max) @ Ipp: 11.2V
• Current - Peak Pulse (10/1000µs): 267.9A (full rating)
• Power - Peak Pulse: 3000W (3kW)
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Type: Zener, Bidirectional

Substitute parts are categorized into two groups:

Direct Substitutes (Identical Electrical and Thermal Ratings): Parts that maintain all electrical specifications and thermal operating range equivalent to the original part.

Similar Substitutes (Reduced Peak Pulse Current Rating): Parts that maintain voltage specifications but operate at reduced peak pulse current (134A vs. 267.9A) and correspondingly reduced power dissipation (1500W vs. 3000W). These are suitable only for applications where the lower current rating is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Full Electrical Equivalence):

SMLJ6.5CA (Bourns Inc.) and SMDJ6.5CA (Alpha & Omega Semiconductor Inc.) are direct functional equivalents with identical peak pulse current (267.9A) and power dissipation (3000W) ratings. Both are active products with ROHS3 compliance. SMLJ6.5CA maintains the original operating temperature range (-55°C ~ 150°C), while SMDJ6.5CA offers the same thermal range. Selection between these two depends on supply chain availability and packaging preference (Tape & Reel vs. standard packaging).

SMDJ6.5CA-HRAT7 (Littelfuse Inc.) provides full electrical equivalence with an extended lower operating temperature limit (-65°C vs. -55°C), making it suitable for applications requiring enhanced cold-temperature performance. This part is active and ROHS3 compliant.

SMLJ6.5CA-TP (Micro Commercial Co) offers full electrical equivalence with an extended upper operating temperature limit (-55°C ~ 175°C vs. -55°C ~ 150°C), providing thermal margin for high-temperature applications. This part is active and ROHS3 compliant.

Reduced-Rating Substitutes (Conditional Use):

SMCJ6.5CA (EVVO Semi), SMCJ6.5CA-TP (Micro Commercial Co), and SMCJ6V5CA (Taiwan Semiconductor Corporation) maintain voltage specifications but operate at reduced peak pulse current (134A or 133.9A) and power dissipation (1500W). These parts are suitable only for applications where the lower current-handling capability is acceptable. All three are active products with ROHS3 compliance.

Compliance and Availability:

All substitute parts listed are ROHS3 compliant and carry EAR99 ECCN classification. Inventory availability varies significantly, with SMCJ6.5CA (EVVO Semi) offering the highest stock level (38,100 pcs), followed by SMDJ6.5CA (Alpha & Omega Semiconductor Inc.) at 61,300 pcs. Direct substitutes SMLJ6.5CA and SMDJ6.5CA-HRAT7 maintain adequate inventory (1,952 pcs and 1,084 pcs respectively).

Frequently Asked Questions (FAQ)

Q: Can SMCJ6.5CA be used as a direct replacement for CD214L-T6.5CALF?

A: SMCJ6.5CA maintains identical voltage specifications (6.5V reverse standoff, 11.2V clamping) and package (DO-214AB, SMC) but operates at reduced peak pulse current (134A vs. 267.9A) and power dissipation (1500W vs. 3000W). It is suitable only for applications where the lower current rating is acceptable. For applications requiring the full 267.9A peak pulse current capability, use SMLJ6.5CA, SMDJ6.5CA, SMDJ6.5CA-HRAT7, or SMLJ6.5CA-TP instead.

Q: What is the difference between SMLJ6.5CA and SMDJ6.5CA?

A: Both parts are direct electrical equivalents with identical voltage ratings (6.5V reverse standoff, 11.2V clamping), peak pulse current (267.9A), and power dissipation (3000W). The primary differences are manufacturer (Bourns Inc. vs. Alpha & Omega Semiconductor Inc.) and packaging availability. Selection depends on supply chain preference and inventory requirements.

Q: Does SMDJ6.5CA-HRAT7 offer any advantage over other direct substitutes?

A: SMDJ6.5CA-HRAT7 extends the lower operating temperature limit to -65°C (compared to -55°C for most alternatives), providing enhanced performance in cold-temperature environments. All other electrical specifications remain equivalent to the original CD214L-T6.5CALF.

Q: Can SMLJ6.5CA-TP be used in high-temperature applications?

A: Yes. SMLJ6.5CA-TP extends the upper operating temperature limit to 175°C (compared to 150°C for the original part), making it suitable for applications requiring thermal margin in elevated-temperature environments. All electrical specifications remain equivalent.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and carry EAR99 ECCN classification, meeting regulatory requirements equivalent to the original CD214L-T6.5CALF.

Q: What packaging options are available for direct substitutes?

A: Direct substitutes are available in Tape & Reel (TR) packaging. SMLJ6.5CA is available in standard packaging, while SMDJ6.5CA-HRAT7, SMDJ6.5CA, and SMLJ6.5CA-TP are available in Tape & Reel format. Verify packaging requirements with your procurement process before final selection.
