SMBJ9.0CD-M3/H Equivalent & Substitute Parts

Part Overview

The SMBJ9.0CD-M3/H is a Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This surface-mount component operates as a bidirectional Zener diode in the DO-214AA (SMB) package, designed for general-purpose transient voltage suppression applications. The part is currently Active in product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when inventory constraints or supply chain requirements necessitate alternative sourcing while maintaining equivalent electrical and mechanical performance within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ9.0CD-M3/H is determined by strict equivalence across the following critical parameters:

• Reverse Standoff Voltage: 9V (Typ)
• Breakdown Voltage: minimum 10V or greater
• Clamping Voltage: maximum 15.4V or lower
• Peak Pulse Current: 39A or greater
• Peak Pulse Power: 600W
• Package: DO-214AA (SMB) surface mount
• Bidirectional Channels: 1
• Type: Zener diode
• Operating Temperature Range: -55°C to 150°C (TJ)
• Compliance: RoHS3, REACH Unaffected, MSL 1

The SMBJ9.0CA-E3/52 meets all substitution criteria within these defined electrical and mechanical tolerances, sharing the same base product number (SMBJ9.0) and manufacturer series designation.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ9.0CD-M3/H and SMBJ9.0CA-E3/52 are Active products with identical compliance certifications: RoHS3 Compliant, REACH Unaffected, and MSL 1 (Unlimited). Selection between these parts should be based on availability and supply chain requirements. The SMBJ9.0CA-E3/52 currently maintains higher inventory levels (33,900 pcs) compared to the SMBJ9.0CD-M3/H (820 pcs), making it suitable for high-volume procurement scenarios. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical performance within specified tolerances, ensuring functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can SMBJ9.0CA-E3/52 be used as a direct replacement for SMBJ9.0CD-M3/H?

A: Yes. Both parts are electrically and mechanically equivalent within the specified parameter tolerances. They share identical reverse standoff voltage (9V), operating temperature range (-55°C to 150°C), package type (DO-214AA/SMB), and peak pulse power rating (600W). The clamping voltage variance (15.1V vs. 15.4V) and peak pulse current difference (39.7A vs. 39A) fall within acceptable substitution limits for general-purpose TVS applications.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the DO-214AA (SMB) surface-mount package with identical mechanical dimensions and land pattern requirements. PCB layout and assembly processes remain unchanged when substituting between these parts.

Q: What compliance certifications apply to both parts?

A: Both the SMBJ9.0CD-M3/H and SMBJ9.0CA-E3/52 are RoHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. No additional handling or storage requirements differ between the two parts.

Q: How do the electrical parameters compare for circuit protection applications?

A: The parts are functionally equivalent for transient voltage suppression. The SMBJ9.0CD-M3/H provides a maximum clamping voltage of 15.1V at peak pulse current, while the SMBJ9.0CA-E3/52 clamps at 15.4V. Both maintain the 9V reverse standoff voltage and 600W peak pulse power rating required for general-purpose protection circuits.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain availability and procurement lead times. Both parts are Active products with identical specifications. The SMBJ9.0CA-E3/52 offers higher inventory availability, making it suitable for immediate procurement needs.
