Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, meeting the compliance profile of the SMBJ6.5CA-HRA. Selection among these equivalents should be based on:

Availability and Lead Time: SMBJ6V5CA (Taiwan Semiconductor Corporation) offers the highest inventory level at 300,300 units. SMBJ6.5CA-13-F (Diodes Incorporated) provides 65,300 units. These options support rapid procurement cycles.

Operating Temperature Considerations: The SMBJ6.5CA-HRA and its equivalents from EVVO Semi and Central Semiconductor Corp operate across -65°C to 150°C. Parts from Diodes Incorporated, Vishay, and Taiwan Semiconductor Corporation operate across -55°C to 150°C, which is suitable for most general-purpose applications. The SMBJ6.5CA-TP from Micro Commercial Co extends to -55°C to 175°C, providing additional thermal margin in high-temperature environments.

Packaging Format: All parts are available in DO-214AA (SMB) surface-mount packages. Packaging options vary between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel formats; selection depends on assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can SMBJ6.5CA-13-F replace SMBJ6.5CA-HRA in all applications?

A: Yes. Both parts share identical electrical specifications (6.5V reverse standoff, 11.2V clamping voltage, 53.6A peak pulse current, 600W peak power) and package format (DO-214AA, SMB). The operating temperature range of SMBJ6.5CA-13-F (-55°C to 150°C) is narrower than the SMBJ6.5CA-HRA (-65°C to 150°C), but this does not affect compatibility in applications operating within the -55°C to 150°C window.

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 high-volume automated assembly. Cut Tape (CT) & Digi-Reel packaging provides smaller quantities on cut tape segments, suitable for lower-volume or prototype applications. Both formats contain identical components; selection depends on assembly volume and equipment compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity ratings, matching the compliance profile of the SMBJ6.5CA-HRA.

Q: Does the manufacturer affect circuit performance?

A: No. All substitute parts meet identical electrical specifications for reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and peak pulse power. Manufacturer differences do not affect functional performance in circuit applications.

Q: Can SMBJ6.5CA-TP be used in applications requiring the full -65°C to 150°C temperature range?

A: SMBJ6.5CA-TP operates from -55°C to 175°C. It cannot be used in applications requiring operation below -55°C. For applications requiring the full -65°C lower temperature limit, use SMBJ6.5CA-HRA, SMBJ6.5CA (EVVO Semi), or 1SMB6.5CA TR13 PBFREE.
