SMBJ130CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ130CE3/TR13 is an active Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, classified as a Zener-type device for surface mount applications. This component is designed for general-purpose transient voltage suppression with a reverse standoff voltage of 130V and peak pulse power rating of 600W. The availability of substitute components from alternative manufacturers becomes necessary to support supply chain flexibility, inventory optimization, and extended sourcing options while maintaining electrical and mechanical compatibility within the design specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for TVS diode alternatives is determined by electrical parameter equivalence and mechanical compatibility. The primary substitution criteria are:

Electrical Parameters:

• Voltage - Reverse Standoff (Typ): 130V (fixed specification)
• Voltage - Breakdown (Min): 144V (minimum threshold)
• Power - Peak Pulse: 600W (dissipation rating)
• Bidirectional Channels: 1
• Type: Zener

Mechanical Parameters:

• Mounting Type: Surface Mount
• Package / Case: DO-214AA (SMB)
• Supplier Device Package: SMB-compatible

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts meeting these criteria are functionally equivalent for circuit-level protection applications. The voltage clamping value and peak pulse current may vary within acceptable margins while maintaining the core protection characteristics.

Parameter Comparison

Engineering Selection Recommendations

SMBJ130CA (Meritek): This substitute part maintains identical reverse standoff and breakdown voltages with marginally improved peak pulse current (2.87A versus 2.6A). The component is ROHS3 compliant with MSL-1 moisture sensitivity rating. Operating temperature minimum of -55°C differs from the primary part; design applications requiring -65°C operation must account for this specification delta.

SMBJ130CA-13-F (Diodes Incorporated): This alternative provides equivalent electrical protection with peak pulse current of 2.9A, exceeding the primary part's 2.6A specification. Full RoHS3 compliance and MSL-1 rating are maintained. Operating temperature range of -55°C to 150°C matches the Meritek alternative, with the same -65°C minimum temperature consideration as noted above.

Both substitute parts carry active product status and demonstrate equivalent functional capacity for general-purpose TVS applications. Selection between alternatives depends on supply chain availability, inventory positioning, and thermal environment constraints within the operating temperature envelope.

Frequently Asked Questions (FAQ)

Q: Can SMBJ130CA and SMBJ130CA-13-F be used interchangeably with SMBJ130CE3/TR13?

A: Yes, both substitute parts provide equivalent transient voltage suppression within the design specification. All three components maintain 130V reverse standoff voltage and 144V minimum breakdown voltage. Differences in voltage clamping (231V, 209V, 209V respectively) and peak pulse current (2.6A, 2.87A, 2.9A) fall within acceptable parameter windows for general-purpose TVS applications.

Q: What is the significance of the voltage clamping difference between the primary part and substitutes?

A: The primary SMBJ130CE3/TR13 exhibits 231V maximum clamping, while both substitute parts clamp at 209V. Both values operate within the 600W power dissipation envelope. Lower clamping voltage in substitute parts results in marginally faster transient suppression response with equivalent energy absorption.

Q: Are there operating temperature restrictions when using substitute parts?

A: The substitute parts specify operating temperatures from -55°C to 150°C, compared to -65°C to 150°C for the primary part. Applications requiring operation below -55°C require the primary SMBJ130CE3/TR13. Applications within -55°C to 150°C thermal range are fully supported by all three components.

Q: Do substitute parts meet the same compliance requirements?

A: Yes. All components—SMBJ130CE3/TR13, SMBJ130CA, and SMBJ130CA-13-F—carry RoHS3 compliance and MSL-1 (Unlimited) moisture sensitivity ratings. ECCN and HTSUS classifications remain identical across all parts.

Q: Is PCB footprint compatibility guaranteed?

A: Yes. All three components utilize DO-214AA (SMB) surface mount packaging, ensuring identical PCB footprint and assembly compatibility without design modifications.
