Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMBJ8.0C-E3/52 is determined by strict equivalence across the following electrical and mechanical parameters:

• Reverse standoff voltage: 8V (Typ)
• Breakdown voltage minimum: 8.89V
• Package type: DO-214AA / SMB surface mount
• Bidirectional channels: 1
• RoHS3 compliance and MSL 1 rating
• Operating temperature range compatibility

Substitute parts are grouped into two categories based on clamping voltage specification:

Category A (15V Clamping): Parts with maximum clamping voltage of 15V at Ipp, electrically identical to the original specification.

Category B (13.6V Clamping): Parts with maximum clamping voltage of 13.6V at Ipp, offering lower clamping performance but maintaining core 8V standoff voltage and general-purpose TVS functionality.

All listed substitutes maintain 600W peak pulse power rating, surface-mount DO-214AA packaging, and full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical Equivalence (15V Clamping):

SMBJ8.0CE3/TR13 (Microchip Technology) provides exact electrical equivalence to the original SMBJ8.0C-E3/52, maintaining 15V maximum clamping voltage and 40A peak pulse current. This part is active in production with ROHS3 compliance and extends the operating temperature range to -65°C, offering enhanced low-temperature performance. Microchip Technology is an established manufacturer with consistent supply availability.

For Active Production Alternatives (13.6V Clamping):

When 13.6V clamping voltage is acceptable for the application, multiple active alternatives are available:

• SMBJ8.0CA-E3/52 (Vishay General Semiconductor) maintains the original manufacturer lineage with active status and identical temperature range.
• SMBJ8.0CA-13-F (Diodes Incorporated) offers the widest inventory availability (4,078 pcs) with active product status and -55°C to 150°C operating range.
• SMBJ8.0CA-TP (Micro Commercial Co) extends maximum operating temperature to 175°C, suitable for high-temperature applications.
• SMBJ8.0CAE3/TR13 (Microchip Technology) provides -65°C low-temperature capability with 13.6V clamping.

All substitute parts maintain DO-214AA surface-mount packaging, RoHS3 compliance, and MSL 1 moisture sensitivity rating, ensuring compatibility with existing PCB designs and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SMBJ8.0C-E3/52 be directly replaced with a 13.6V clamping alternative?

A: Substitution depends on circuit requirements. The original part specifies 15V maximum clamping voltage. Parts with 13.6V clamping provide lower voltage suppression and may be suitable if the circuit design accommodates this lower clamping threshold. Verify that the protected circuit can tolerate the reduced clamping voltage before substitution.

Q: What is the difference between SMBJ8.0CE3/TR13 and SMBJ8.0CAE3/TR13?

A: SMBJ8.0CE3/TR13 maintains 15V clamping voltage identical to the original part, while SMBJ8.0CAE3/TR13 reduces clamping to 13.6V. Both are Microchip Technology products with active status. SMBJ8.0CE3/TR13 is the direct electrical equivalent; SMBJ8.0CAE3/TR13 is a lower-clamping alternative.

Q: Are all substitute parts available in the same packaging?

A: All listed substitutes use DO-214AA (SMB) surface-mount packaging, maintaining mechanical compatibility with the original SMBJ8.0C-E3/52. Tape & Reel (TR) packaging is standard across all active alternatives, suitable for automated assembly processes.

Q: What is the significance of the extended temperature range in SMBJ8.0CA-TP?

A: SMBJ8.0CA-TP (Micro Commercial Co) operates to 175°C maximum junction temperature, compared to 150°C for most alternatives. This extended range is beneficial for applications in high-temperature environments or circuits with elevated thermal stress, though the original part specification is -55°C to 150°C.

Q: Why is the original SMBJ8.0C-E3/52 listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. The listed active alternatives provide equivalent or compatible functionality for new designs and production continuity. Existing inventory of the original part (818 pcs) remains available, but long-term sourcing should transition to active alternatives.

Q: Do all substitutes maintain RoHS3 compliance?

A: Yes, all listed substitute parts are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental and regulatory compliance status.
