SMBJ54CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ54CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This bidirectional Zener diode operates with a reverse standoff voltage of 54V and provides clamping at 96.3V maximum, with a peak pulse current rating of 6.2A. The component is housed in a DO-214AA (SMB) surface mount package and is supplied on tape and reel. The part maintains active product status and full RoHS3 compliance.

Equivalent and substitute parts are identified based on matching electrical characteristics within the TVS diode category, specifically those sharing the same reverse standoff voltage, breakdown voltage range, package type, and general-purpose application profile.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ54CE3/TR13 are identified based on the following critical electrical and mechanical parameters:

Matching Criteria:

• Reverse Standoff Voltage: 54V (typical)
• Breakdown Voltage (Minimum): 60V
• Package Type: DO-214AA / SMB surface mount
• Bidirectional Channels: 1
• Type: Zener TVS diode
• Application: General Purpose
• Product Status: Active

Substitution Logic: Parts are considered equivalent when they maintain the same reverse standoff voltage and breakdown voltage specifications, ensuring identical circuit protection thresholds. The DO-214AA package compatibility allows direct PCB footprint substitution. Variations in clamping voltage and peak pulse current are noted but do not preclude substitution when the core voltage protection parameters align.

Parameter Comparison

Engineering Selection Recommendations

SMBJ54CA (Fairchild Semiconductor): This substitute maintains identical reverse standoff voltage (54V) and breakdown voltage (60V minimum) specifications. The clamping voltage is 87.1V, which is lower than the primary part's 96.3V, and peak pulse current is 6.9A compared to 6.2A. Both parts share the DO-214AA package and 600W peak pulse power rating. The operating temperature range is -55°C to 150°C, which is narrower than the primary part's -65°C to 150°C range. Product status is active. RoHS compliance status is not specified for this variant.

SMBJ54CA-13-F (Diodes Incorporated): This substitute is supplied on tape and reel (TR) packaging, matching the primary part's delivery format. Electrical specifications are identical to the Fairchild SMBJ54CA variant: 54V reverse standoff, 60V minimum breakdown, 87.1V clamping voltage, and 6.9A peak pulse current. The DO-214AA package ensures PCB footprint compatibility. Operating temperature range is -55°C to 150°C. Product status is active with ROHS3 compliance and MSL 1 (Unlimited) rating, matching the primary part's compliance profile.

All substitute parts maintain the same voltage protection thresholds and package compatibility required for direct circuit substitution in general-purpose TVS applications.

Frequently Asked Questions (FAQ)

Q: Can SMBJ54CA and SMBJ54CA-13-F be used interchangeably with SMBJ54CE3/TR13?

A: Yes, both parts share the critical voltage specifications (54V reverse standoff, 60V minimum breakdown) and DO-214AA package type required for circuit substitution. The primary differences are clamping voltage (87.1V versus 96.3V) and peak pulse current (6.9A versus 6.2A), which represent performance variations within the same protection class rather than incompatibilities.

Q: What is the significance of the different clamping voltages?

A: The SMBJ54CE3/TR13 clamps at 96.3V maximum, while the SMBJ54CA and SMBJ54CA-13-F clamp at 87.1V maximum. Both values fall within acceptable protection parameters for 54V standoff applications. The lower clamping voltage of the substitute parts provides slightly tighter voltage regulation during transient events.

Q: Are the tape and reel packaging options interchangeable?

A: The SMBJ54CE3/TR13 is supplied on tape and reel (TR). The SMBJ54CA-13-F is also supplied on tape and reel. The SMBJ54CA packaging format is not specified. For applications requiring tape and reel delivery, the SMBJ54CA-13-F maintains format compatibility with the primary part.

Q: What is the impact of the operating temperature range difference?

A: The SMBJ54CE3/TR13 operates from -65°C to 150°C, while the substitute parts operate from -55°C to 150°C. The primary part supports a wider low-temperature range. For applications operating below -55°C, the SMBJ54CE3/TR13 is required. For standard industrial temperature ranges, the substitute parts are suitable.

Q: Are all parts RoHS3 compliant?

A: The SMBJ54CE3/TR13 and SMBJ54CA-13-F are both ROHS3 compliant. The SMBJ54CA (Fairchild) RoHS compliance status is not specified in the provided data. For applications requiring verified RoHS3 compliance, the SMBJ54CA-13-F (Diodes Incorporated) is the recommended substitute.

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

A: The SMBJ54CE3/TR13 has MSL 1 (Unlimited). The SMBJ54CA-13-F also has MSL 1 (Unlimited). The SMBJ54CA (Fairchild) MSL rating is not specified. For applications with strict moisture sensitivity requirements, the SMBJ54CA-13-F maintains identical MSL classification.

Q: Can these parts be used in power line protection applications?

A: No. All three parts are designated for general-purpose applications, not power line protection. The product specifications explicitly indicate "Power Line Protection: No" for all variants.
