SMBJ90CA-13 Equivalent & Substitute Parts

Part Overview

The SMBJ90CA-13 is a Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose transient voltage protection in surface-mount applications. This component features a 90V reverse standoff voltage with a 146V maximum clamping voltage and 4.1A peak pulse current capability in an SMB (DO-214AA) package.

The SMBJ90CA-13 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Substitute Part Grouping Explanation

Substitute parts for the SMBJ90CA-13 must satisfy the following electrical and mechanical criteria:

• Voltage Rating: Reverse standoff voltage of 90V (±0V tolerance for direct substitution)
• Breakdown Voltage: Minimum 100V
• Clamping Voltage: Maximum 146V at peak pulse current
• Peak Pulse Current: 4.1A at 10/1000µs waveform
• Peak Pulse Power: 600W
• Package: DO-214AA / SMB surface-mount package
• Bidirectional Channels: 1 channel
• Application: General-purpose transient voltage suppression

The SMBJ90CA manufactured by MDD meets all specified electrical parameters and package requirements, establishing it as a direct functional equivalent to the SMBJ90CA-13.

Parameter Comparison

*Operating temperature range of MDD substitute is -50 to 150°C, which covers the upper portion of the original specification. Applications requiring operation below -50°C require design review.

Engineering Selection Recommendations

Primary Substitute: SMBJ90CA (MDD)

The SMBJ90CA manufactured by MDD is the recommended substitute for the discontinued SMBJ90CA-13. This part satisfies all critical electrical parameters and package specifications required for direct replacement.

Compliance Status:

• MDD SMBJ90CA: ROHS3 Compliant, REACH Unaffected
• Original SMBJ90CA-13: RoHS non-compliant

The MDD substitute offers improved regulatory compliance for new designs and production applications. Inventory availability is confirmed at 29,200 pieces in stock as new original components.

Packaging Consideration: The MDD substitute is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. Confirm packaging compatibility with your procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can SMBJ90CA (MDD) be used as a direct replacement for SMBJ90CA-13 (Diodes Inc.)?

A: Yes. Both parts share identical electrical specifications for voltage rating (90V standoff, 100V breakdown, 146V clamping), peak pulse current (4.1A), power dissipation (600W), and package format (DO-214AA SMB). Pin-to-pin and functional compatibility is confirmed.

Q: What is the difference in operating temperature range?

A: The original SMBJ90CA-13 operates from -55 to 150°C. The MDD substitute operates from -50 to 150°C. For applications requiring operation below -50°C, design verification is necessary.

Q: Does the packaging format affect compatibility?

A: The MDD substitute is supplied in Tape & Reel (TR) format for automated assembly. The component itself uses the same DO-214AA SMB package as the original. Confirm your assembly process supports TR packaging.

Q: What is the regulatory compliance difference?

A: The original part is RoHS non-compliant. The MDD substitute is ROHS3 compliant, making it suitable for applications with RoHS requirements. Both parts are REACH unaffected.

Q: Are there any electrical performance differences?

A: No. All specified electrical parameters—voltage ratings, clamping characteristics, peak pulse current, and power dissipation—are identical between the original and substitute parts.
