CD214B-T6.5CALF Equivalent & Substitute Parts
Part Overview
The CD214B-T6.5CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., classified as a Zener-type bidirectional TVS in the SMB (DO-214AA) package. This component is designed for general-purpose transient voltage suppression applications with a 6.5V reverse standoff voltage and 11.2V maximum clamping voltage. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production requirements.

Substitute Part Grouping Explanation
Substitution for the CD214B-T6.5CALF is determined by strict electrical and mechanical parameter matching:
Primary Substitution Criteria:
- Voltage - Reverse Standoff (Typ): 6.5V
- Voltage - Clamping (Max) @ Ipp: 11.2V
- Current - Peak Pulse (10/1000µs): 53.6A (±tolerance)
- Package / Case: DO-214AA, SMB
- Mounting Type: Surface Mount
- RoHS3 Compliance
- MSL Rating: 1 (Unlimited)
Direct Equivalents maintain all electrical parameters within specification. Similar Substitutes may have minor variations in peak pulse current (within ±5%) or operating temperature range while maintaining the core voltage and clamping specifications.

Engineering Selection Recommendations
Direct Substitutes (Preferred): SMBJ6.5CA (EVVO Semi), SMBJ6V5CA (Taiwan Semiconductor Corporation), and TV06B6V5JB-HF (Comchip Technology) provide electrical equivalence to the CD214B-T6.5CALF with identical voltage and clamping specifications. All are active products with ROHS3 compliance and MSL 1 rating. SMBJ6.5CA offers the widest operating temperature range (-65°C to 150°C) and highest inventory availability (146,145 pcs).
Alternative Substitutes (Extended Temperature): SMBJ6.5CA-TP (Micro Commercial Co) extends the upper operating temperature to 175°C while maintaining electrical equivalence, suitable for applications requiring enhanced thermal performance.
Similar Substitute (Voltage Variant): SMBJ7.0CA (MDD) represents a voltage-rated variant with 7V reverse standoff and 12V clamping. This part is suitable only for applications where the higher voltage rating is acceptable and does not create circuit incompatibility.
All substitute parts maintain DO-214AA (SMB) package compatibility, surface mount configuration, and regulatory compliance (ROHS3, MSL 1).
Frequently Asked Questions (FAQ)
Q: Can SMBJ6.5CA directly replace CD214B-T6.5CALF? A: Yes. SMBJ6.5CA matches all critical electrical parameters: 6.5V reverse standoff, 11.2V clamping voltage, 53.6A peak pulse current, and DO-214AA package. Both are ROHS3 compliant with MSL 1 rating.
Q: What is the difference between SMBJ6.5CA and SMBJ6.5CA-TR? A: Both maintain identical voltage specifications (6.5V/11.2V). SMBJ6.5CA-TR (STMicroelectronics) has a slightly higher peak pulse current rating of 56A versus 53.6A, and identical operating temperature range (-55°C to 150°C). The difference in peak pulse current is within acceptable tolerance for most applications.
Q: Is SMBJ7.0CA a suitable replacement? A: SMBJ7.0CA is a voltage variant with 7V reverse standoff and 12V clamping, not a direct equivalent. Use only if circuit design permits the higher voltage rating without functional degradation.
Q: What packaging options are available for substitutes? A: All substitute parts are available in DO-214AA (SMB) surface mount package. Packaging formats include Cut Tape (CT), Digi-Reel®, and Tape & Reel (TR) options depending on manufacturer and part number.
Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original CD214B-T6.5CALF specifications.
Q: Which substitute has the best availability? A: SMBJ6V5CA (Taiwan Semiconductor Corporation) offers the highest inventory with 300,300 pcs in stock, followed by SMBJ6.5CA (EVVO Semi) with 146,145 pcs.
