SMBJ9.0CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ9.0CE3/TR13 is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Microchip Technology in the DO-214AA (SMB) surface mount package. This component is rated for 9V reverse standoff voltage with a 16.9V maximum clamping voltage and 35.5A peak pulse current capacity. The device is designed for general-purpose transient voltage suppression applications and is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified based on matching the core electrical parameters: 9V reverse standoff voltage, 10V minimum breakdown voltage, DO-214AA/SMB package configuration, surface mount mounting type, 600W peak pulse power rating, and general-purpose application classification. Equivalent devices maintain functional interchangeability within these specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ9.0CE3/TR13 are qualified based on the following electrical and mechanical parameters:

Matching Criteria:

• Voltage - Reverse Standoff: 9V (typical)
• Voltage - Breakdown: 10V (minimum)
• Package / Case: DO-214AA or SMB
• Mounting Type: Surface Mount
• Power - Peak Pulse: 600W
• Type: Zener
• Bidirectional Channels: 1
• Applications: General Purpose
• RoHS3 Compliance
• REACH Unaffected Status

Allowable Variation:

• Voltage - Clamping (Max) @ Ipp: 15.4V to 16.9V (within acceptable suppression range)
• Current - Peak Pulse (10/1000µs): 35.5A to 40A (within pulse handling capability)
• Operating Temperature: -55°C to -65°C minimum; 150°C maximum

All substitute parts maintain identical base product number classification (SMBJ9.0 or SMBJ9V0) and are manufactured by qualified semiconductor suppliers with active product status.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full compliance with RoHS3 and REACH regulatory requirements. Selection between the SMBJ9.0CE3/TR13 and substitute devices is determined by availability, packaging format, and specific clamping voltage tolerance requirements.

Microchip SMBJ9.0CE3/TR13: Offers the highest clamping voltage specification at 16.9V maximum, providing the most conservative transient suppression margin. Supplied in Tape & Reel packaging. Suitable for applications requiring maximum voltage clamping performance within the 9V class.

Taiwan Semiconductor SMBJ9.0CA: Provides 15.4V clamping voltage with 40A peak pulse current capacity. Available in standard packaging. Highest inventory availability (23,200 units).

Diodes Incorporated SMBJ9.0CA-13-F: Delivers 15.4V clamping voltage with 39A peak pulse current capacity. Supplied in Tape & Reel packaging. Largest inventory stock (98,300 units).

Taiwan Semiconductor SMBJ9V0CA: Provides 15.4V clamping voltage with 39A peak pulse current capacity. Available in Cut Tape and Digi-Reel packaging formats.

All devices operate across the -55°C to 150°C temperature range, with the SMBJ9.0CE3/TR13 extending the lower operating limit to -65°C. Peak pulse power rating is uniform at 600W across all variants.

Frequently Asked Questions (FAQ)

Q: Can SMBJ9.0CA substitute for SMBJ9.0CE3/TR13 in all applications?

A: SMBJ9.0CA is electrically compatible for general-purpose transient voltage suppression applications. The primary difference is clamping voltage: SMBJ9.0CA clamps at 15.4V maximum versus 16.9V for the SMBJ9.0CE3/TR13. Applications requiring the lower clamping voltage specification of SMBJ9.0CA are suitable for direct substitution. Verify clamping voltage requirements against circuit design specifications.

Q: What is the difference between SMBJ9.0CA and SMBJ9V0CA?

A: Both devices share identical electrical specifications: 9V reverse standoff, 10V breakdown minimum, 15.4V clamping maximum, and 600W peak pulse power. The primary distinction is packaging format. SMBJ9.0CA is available in standard packaging, while SMBJ9V0CA is supplied in Cut Tape and Digi-Reel formats. Part numbering reflects manufacturer designation conventions.

Q: Why does SMBJ9.0CE3/TR13 have a lower operating temperature minimum (-65°C) compared to substitute parts (-55°C)?

A: Operating temperature range is a specified characteristic of each manufacturer's design. The SMBJ9.0CE3/TR13 is qualified for -65°C minimum junction temperature, while substitute parts are qualified to -55°C minimum. For applications operating below -55°C, the SMBJ9.0CE3/TR13 is the appropriate selection.

Q: Are all substitute parts available in Tape & Reel packaging?

A: SMBJ9.0CE3/TR13 and SMBJ9.0CA-13-F are supplied in Tape & Reel (TR) format. SMBJ9.0CA is available in standard packaging (format not specified in data). SMBJ9V0CA is available in Cut Tape (CT) and Digi-Reel packaging. Verify packaging requirements for automated assembly processes.

Q: What is the significance of the 1A difference in peak pulse current between SMBJ9.0CE3/TR13 (35.5A) and SMBJ9.0CA (40A)?

A: Peak pulse current capacity indicates the maximum transient current the device can suppress during a 10/1000µs pulse event. SMBJ9.0CA's 40A rating provides 4.5A additional margin over the SMBJ9.0CE3/TR13's 35.5A rating. Both devices maintain 600W peak pulse power dissipation. Selection depends on circuit transient current requirements.

Q: Do all substitute parts meet the same regulatory compliance standards?

A: All identified substitute parts are RoHS3 compliant and REACH unaffected, matching the SMBJ9.0CE3/TR13 compliance profile. Moisture sensitivity level is 1 (unlimited) across all variants. All devices carry EAR99 ECCN classification and 8541.10.0080 HTSUS code.

Q: Can SMBJ9.0CA-13-F be used as a direct replacement in existing designs?

A: SMBJ9.0CA-13-F is electrically and mechanically compatible with SMBJ9.0CE3/TR13 for surface mount applications. Both use DO-214AA/SMB package configuration. The -13-F suffix indicates Diodes Incorporated's internal packaging designation. Verify clamping voltage tolerance (15.4V vs. 16.9V) against circuit requirements before implementation.
