Substitute Part Grouping Explanation

Substitution of the CD214C-T8.0CALF is determined by the following critical parameters:

Voltage - Reverse Standoff (Typ): 8V
Voltage - Clamping (Max) @ Ipp: 13.6V
Current - Peak Pulse (10/1000µs): 110.3A or higher
Power - Peak Pulse: 1500W or higher
Package / Case: DO-214AB (SMC)

Substitute parts are grouped into two categories:

Direct Equivalents: Parts with identical electrical specifications (110.3A peak pulse current, 1500W peak power) and active product status from multiple manufacturers.

Higher-Performance Alternatives: Parts with superior current handling (220.6A peak pulse current, 3000W peak power) that maintain voltage compatibility and package specifications, suitable for applications requiring enhanced transient protection margin.

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents):

SMCJ8.0CA from Taiwan Semiconductor Corporation and SMCJ8.0CA-M3/57T from Vishay are recommended as primary substitutes. Both maintain identical electrical specifications (8V standoff, 13.6V clamping, 110.3A peak pulse, 1500W peak power) and are in active production status with ROHS3 compliance. Taiwan Semiconductor's SMCJ8.0CA offers the highest inventory availability (84,100 pcs) for supply chain continuity.

Extended Temperature Range Alternative:

SMCJ8.0CA-HR and SMCJ8.0CA-HRA from Littelfuse extend the lower operating temperature limit to -65°C, suitable for applications requiring enhanced cold-temperature performance while maintaining all other electrical parameters.

Higher Operating Temperature Option:

SMCJ8.0CA-TP from Micro Commercial Co supports operating temperatures up to 175°C, providing thermal margin for high-ambient applications while maintaining standard electrical specifications.

Enhanced Protection Alternative:

SMDJ8.0CA from Alpha & Omega Semiconductor Inc. provides doubled peak pulse current (220.6A) and quadrupled peak power (3000W) while maintaining voltage compatibility. This part is suitable for applications requiring additional transient protection margin or higher energy absorption capacity.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can SMDJ8.0CA be used as a direct replacement for CD214C-T8.0CALF?

A: SMDJ8.0CA is electrically compatible with identical voltage specifications (8V standoff, 13.6V clamping) and package (DO-214AB, SMC). However, it provides enhanced current handling (220.6A vs. 110.3A) and power dissipation (3000W vs. 1500W). This higher performance does not create compatibility issues and may provide additional protection margin in the application circuit.

Q: What is the difference between SMCJ8.0CA and SMCJ8.0CA-M3/57T?

A: Both parts are electrically identical with 8V standoff voltage, 13.6V clamping voltage, 110.3A peak pulse current, and 1500W peak power. SMCJ8.0CA-M3/57T is the Vishay TransZorb® series variant supplied in tape and reel packaging, while SMCJ8.0CA from Taiwan Semiconductor is available in bulk packaging. Selection depends on packaging and supply requirements.

Q: Are Littelfuse SMCJ8.0CA-HR and SMCJ8.0CA-HRA interchangeable?

A: Both Littelfuse parts maintain identical electrical specifications and operating temperature range (-65°C to 150°C). The suffix variations indicate different packaging or tape specifications. Verify specific packaging requirements with the supplier before selection.

Q: Does the extended temperature range of SMCJ8.0CA-TP (-55°C to 175°C) affect electrical performance?

A: The extended upper temperature limit to 175°C does not alter the core electrical specifications (8V standoff, 13.6V clamping, 110.3A peak pulse, 1500W peak power). Selection should be based on application thermal requirements.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. REACH status varies by manufacturer; verify specific regulatory requirements for your application region.
