Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ64CD-M3/I is determined by strict equivalence in the following electrical and mechanical parameters:

• Reverse standoff voltage: 64V (nominal)
• Package type: DO-214AA (SMB surface mount)
• Bidirectional channel configuration: 1 channel
• Zener diode type classification
• Operating temperature range: -55°C to 150°C
• RoHS3 compliance and MSL Level 1 rating

The substitute part SMBJ64CA-E3/5B maintains identical reverse standoff voltage, package configuration, and thermal operating range. Clamping voltage and peak pulse current parameters remain within the tolerance band established for this product category, confirming functional equivalence for general-purpose transient suppression applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ64CD-M3/I and SMBJ64CA-E3/5B are active production components manufactured by Vishay General Semiconductor - Diodes Division. Both parts carry ROHS3 compliance certification and MSL Level 1 rating, confirming suitability for standard surface mount assembly processes without moisture sensitivity constraints.

Selection between these parts is based on inventory availability and application-specific requirements. The SMBJ64CA-E3/5B offers higher inventory availability (4001 pieces) compared to the SMBJ64CD-M3/I (798 pieces). Electrical parameter variations between the two parts fall within acceptable tolerance bands for general-purpose transient voltage suppression, with clamping voltage differing by 1V and peak pulse current by 0.08A.

Frequently Asked Questions (FAQ)

Q: Can SMBJ64CA-E3/5B directly replace SMBJ64CD-M3/I in existing designs?

A: Yes. Both parts share identical reverse standoff voltage (64V), package configuration (DO-214AA SMB), thermal operating range (-55°C to 150°C), and compliance certifications. Electrical parameters remain within acceptable tolerance for general-purpose applications.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturing part number suffixes and minor variations in breakdown voltage (72.2V vs. 71.1V) and clamping voltage (102V vs. 103V). These variations remain within the tolerance specification for the SMBJ64 base product family.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both components use identical DO-214AA (SMB) surface mount packaging and carry MSL Level 1 rating, confirming compatibility with standard reflow soldering processes without special moisture handling requirements.

Q: What determines substitution eligibility for SMBJ64 series TVS diodes?

A: Substitution is determined by matching reverse standoff voltage, package type, bidirectional channel count, operating temperature range, and compliance certifications. Clamping voltage and peak pulse current must remain within the tolerance band established for the base product number.

Q: Is inventory status a factor in component selection?

A: Inventory availability may influence procurement decisions. The SMBJ64CA-E3/5B maintains significantly higher stock levels, which may reduce lead time for high-volume production requirements.
