SMBJ9.0E3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ9.0E3/TR13 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Microchip Technology in the DO-214AA (SMB) surface mount package. This component is designed for general-purpose transient voltage suppression applications with a 9V reverse standoff voltage and 16.9V maximum clamping voltage. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical characteristics within the SMBJ9.0 series, including reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current rating, and power dissipation capacity. Substitute parts maintain compatibility with the same surface mount package and thermal operating range requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ9.0E3/TR13 are identified within the SMBJ9.0 series based on the following critical electrical parameters:

Matching Criteria:

• Reverse standoff voltage: 9V (typical)
• Breakdown voltage minimum: 10V
• Unidirectional Zener diode type with single channel
• Surface mount DO-214AA (SMB) package
• Peak pulse power rating: 600W
• General-purpose transient voltage suppression applications
• RoHS3 compliance and MSL 1 rating

Allowable Variations:

• Clamping voltage (Max) @ Ipp: 15.4V to 16.9V
• Peak pulse current (10/1000µs): 35.5A to 40A
• Operating temperature range: -55°C to -65°C minimum; 150°C maximum

All substitute parts maintain electrical compatibility within the specified parameter tolerances and are qualified for identical application requirements.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are active production components with RoHS3 compliance and MSL 1 rating, matching the regulatory and environmental requirements of the SMBJ9.0E3/TR13.

Electrical Compatibility: The SMBJ9.0A (Taiwan Semiconductor), SMBJ9.0A-13-F (Diodes Incorporated), and SMBJ9V0A (Taiwan Semiconductor) are electrically compatible substitutes. All parts share identical reverse standoff voltage (9V), breakdown voltage minimum (10V), and peak pulse power rating (600W). Clamping voltage variations range from 15.4V to 16.9V, and peak pulse current ratings range from 35.5A to 40A, all within acceptable operating parameters for the SMBJ9.0 series application envelope.

Temperature Operating Range: The SMBJ9.0E3/TR13 operates from -65°C to 150°C. Substitute parts operate from -55°C to 150°C. Applications requiring operation below -55°C must retain the original SMBJ9.0E3/TR13 component.

Packaging and Availability: All substitute parts are supplied in DO-214AA (SMB) surface mount package format. The SMBJ9.0A-13-F is supplied in Tape & Reel packaging identical to the original part. Taiwan Semiconductor SMBJ9.0A and SMBJ9V0A variants offer higher inventory availability (3100 and 6986 units respectively) compared to the original part (741 units).

Compliance Status: All parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory continuity in design and procurement.

Frequently Asked Questions (FAQ)

Q: Can SMBJ9.0A substitute for SMBJ9.0E3/TR13 in all applications?

A: The SMBJ9.0A is electrically compatible for applications operating within the -55°C to 150°C temperature range. Applications requiring operation below -55°C must use the original SMBJ9.0E3/TR13, which operates to -65°C.

Q: What is the difference between clamping voltage specifications of 16.9V and 15.4V?

A: The SMBJ9.0E3/TR13 specifies a maximum clamping voltage of 16.9V at peak pulse current, while substitute parts specify 15.4V. Both values fall within the SMBJ9.0 series design envelope and are acceptable for general-purpose transient voltage suppression. Component selection should be based on specific circuit clamping voltage requirements.

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

A: The SMBJ9.0A-13-F and SMBJ9V0A are supplied in Tape & Reel (TR) packaging. The SMBJ9.0A (Taiwan Semiconductor) packaging format is not specified in available data. Verify packaging requirements with the supplier before procurement.

Q: Do substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts carry MSL 1 (Unlimited) rating, identical to the SMBJ9.0E3/TR13. No additional moisture handling precautions are required when substituting between these parts.

Q: What is the peak pulse current difference between the original and substitute parts?

A: The SMBJ9.0E3/TR13 is rated for 35.5A peak pulse current. Substitute parts are rated for 39A to 40A peak pulse current. Higher current ratings in substitute parts provide equivalent or improved performance for transient suppression applications.

Q: Are all parts RoHS3 compliant?

A: Yes. The SMBJ9.0E3/TR13 and all identified substitute parts are RoHS3 compliant with REACH unaffected status, ensuring regulatory compliance for EU and international markets.

Q: Can substitute parts be used interchangeably on existing PCBs?

A: Yes. All substitute parts use identical DO-214AA (SMB) surface mount package format and pinout, allowing direct PCB substitution without layout modifications.
