Engineering Selection Recommendations

Primary Recommendation: SMBJ6.5CA-13-F (Diodes Incorporated)

The SMBJ6.5CA-13-F is the direct successor to the discontinued SMBJ6.5CA-13, manufactured by the same supplier. It maintains identical electrical specifications and operating temperature range while achieving ROHS3 compliance. This part is actively produced with high inventory availability (65,300 pcs), making it the preferred choice for new designs and replacement applications.

Alternative Selections:

SMBJ6V5CA (Taiwan Semiconductor Corporation): Offers the highest inventory availability (300,300 pcs) with identical electrical performance and ROHS3 compliance. Suitable for high-volume production requirements.
SMBJ6.5CA-TP (Micro Commercial Co): Provides extended operating temperature range (-55°C to 175°C) for applications requiring higher thermal performance. ROHS3 compliant with active production status.
SMBJ6.5CA-E3/52 (Vishay General Semiconductor): TransZorb® series part with identical specifications and ROHS3 compliance. Established supplier with consistent quality standards.
SMBJ6.5CA (EVVO Semi): Extended lower operating temperature limit (-65°C) with ROHS3 compliance. Suitable for applications requiring enhanced cold-temperature performance.

All substitute parts are actively produced, ROHS3 compliant, and electrically equivalent for direct circuit replacement.

Frequently Asked Questions (FAQ)

Q: Can SMBJ6.5CA-13-F directly replace SMBJ6.5CA-13 without circuit modification?

A: Yes. The SMBJ6.5CA-13-F maintains identical voltage ratings (6.5V reverse standoff, 11.2V clamping), peak pulse current (53.6A), power dissipation (600W), and operating temperature range (-55°C to 150°C). The DO-214AA (SMB) package is identical. No circuit changes are required.

Q: What is the difference between tape & reel and cut tape packaging?

A: Tape & reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly lines. Cut tape (CT) supplies components on cut segments of carrier tape, suitable for manual assembly or smaller production runs. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Does the SMBJ6.5CA-TP operating temperature range of -55°C to 175°C affect substitutability?

A: The extended upper temperature limit of 175°C (versus 150°C for the original part) does not prevent substitution. The part remains functionally equivalent at the original operating range. The extended range provides additional thermal margin for applications operating at elevated temperatures.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts except the original SMBJ6.5CA-13 are ROHS3 compliant. The original part is RoHS non-compliant. For applications requiring RoHS compliance, select from the active substitute parts listed.

Q: What is the significance of the 56A peak pulse current in SMBJ6.5CA-TR versus 53.6A in other parts?

A: The SMBJ6.5CA-TR specifies 56A peak pulse current, which exceeds the 53.6A minimum requirement. This represents enhanced current handling capability and does not prevent substitution. The part remains suitable for applications designed for 53.6A operation.

Q: Can I use SMBJ6.5CA (EVVO Semi) in applications requiring -55°C minimum operating temperature?

A: Yes. The SMBJ6.5CA specifies -65°C minimum operating temperature, which exceeds the -55°C requirement of the original part. The extended lower temperature range provides additional thermal margin and does not affect substitutability.
