SMBJ64E3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ64E3/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This component operates with a 64V reverse standoff voltage and provides clamping at 114V maximum, with a peak pulse current rating of 5.3A. The device is supplied in Tape & Reel packaging and maintains Active product status with full RoHS3 compliance.

Equivalent and substitute parts are identified based on matching electrical performance parameters within the SMBJ64 base product family, including reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and power dissipation ratings. Substitute devices must maintain compatibility with the DO-214AA (SMB) surface-mount package and operate within the specified temperature range for general-purpose TVS applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ64E3/TR13 are identified within the SMBJ64 base product family. Substitution eligibility is determined by the following critical electrical parameters:

Primary Matching Criteria:

• Voltage - Reverse Standoff (Typ): 64V
• Voltage - Breakdown (Min): 71.1V
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional (1 channel)

Secondary Performance Parameters:

• Voltage - Clamping (Max) @ Ipp: 103V to 114V range
• Current - Peak Pulse (10/1000µs): 5.3A to 5.83A range
• Power - Peak Pulse: 600W

All substitute parts maintain identical reverse standoff and breakdown voltage specifications, ensuring functional equivalence in circuit protection applications. Variations in clamping voltage and peak pulse current remain within acceptable operating margins for general-purpose TVS applications. All substitute devices are manufactured in the DO-214AA (SMB) package and support surface-mount assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and full compliance with RoHS3 and REACH regulations, ensuring regulatory compatibility with the original SMBJ64E3/TR13 component.

SMBJ64A (Meritek): This substitute provides equivalent electrical performance with a clamping voltage of 103V and peak pulse current of 5.83A. The operating temperature range extends to -55°C minimum, which is narrower than the original component's -65°C specification. This device is suitable for applications where the lower temperature limit is not a constraint.

SMBJ64A-13-F (Diodes Incorporated): This substitute offers comparable electrical characteristics with a clamping voltage of 103V and peak pulse current of 5.8A. The operating temperature range is -55°C to 150°C, matching the Meritek variant. This device is supplied in Tape & Reel packaging, consistent with the original component's packaging format.

Both substitute parts maintain the critical reverse standoff voltage of 64V and breakdown voltage of 71.1V, ensuring functional equivalence in circuit protection. The reduction in maximum clamping voltage from 114V to 103V represents improved clamping performance. All devices are manufactured in the DO-214AA (SMB) package and support surface-mount assembly processes.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the SMBJ64E3/TR13?

A: Substitution eligibility is based on matching the reverse standoff voltage (64V), breakdown voltage (71.1V), package type (DO-214AA/SMB), mounting method (surface mount), and device type (unidirectional Zener). All substitute parts must maintain these core electrical and mechanical specifications.

Q: How do the clamping voltage differences affect circuit performance?

A: The SMBJ64E3/TR13 clamps at a maximum of 114V, while substitute parts (SMBJ64A and SMBJ64A-13-F) clamp at 103V. Lower clamping voltage provides more aggressive overvoltage suppression. Both values fall within the acceptable range for general-purpose TVS applications protecting 64V circuits.

Q: Are there temperature range limitations when using substitute parts?

A: The original SMBJ64E3/TR13 operates from -65°C to 150°C. Both substitute parts operate from -55°C to 150°C, representing a 10°C reduction in the minimum operating temperature. Applications requiring operation below -55°C must use the original Microchip component.

Q: Can substitute parts be used in Tape & Reel applications?

A: The SMBJ64A-13-F (Diodes Incorporated) is supplied in Tape & Reel packaging, matching the original component's packaging format. The SMBJ64A (Meritek) packaging format is not specified in the provided data. Verify packaging availability with the supplier for specific production requirements.

Q: Are all substitute parts RoHS3 and REACH compliant?

A: Yes. All identified substitute parts (SMBJ64A and SMBJ64A-13-F) maintain RoHS3 compliance and REACH Unaffected status, matching the regulatory compliance of the original SMBJ64E3/TR13 component.

Q: What is the difference in peak pulse current between the main part and substitutes?

A: The SMBJ64E3/TR13 is rated for 5.3A peak pulse current. Substitute parts are rated for 5.83A (Meritek) and 5.8A (Diodes Incorporated). Higher peak pulse current ratings indicate improved transient handling capability within the same 600W power dissipation envelope.

Q: Do substitute parts maintain the same DO-214AA package dimensions?

A: Yes. All substitute parts use the DO-214AA (SMB) package, ensuring mechanical and electrical compatibility with the original component's footprint and assembly process.
