SMBJ54CA-TP Equivalent & Substitute Parts

Part Overview

The SMBJ54CA-TP is a transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional Zener diode operates with a 54V reverse standoff voltage and provides 87.1V clamping at peak pulse current, delivering 600W peak pulse power dissipation in a compact DO-214AA (SMB) package. The part is active in production and RoHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility, enabling procurement flexibility while maintaining circuit protection specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ54CA-TP are qualified based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 54V
• Voltage - Breakdown (Min): 60V
• Voltage - Clamping (Max) @ Ipp: 87.1V
• Current - Peak Pulse (10/1000µs): 6.9A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Type: Zener
• Bidirectional Channels: 1

All identified substitutes meet these electrical specifications and are packaged in the same DO-214AA (SMB) surface-mount form factor, ensuring direct circuit board compatibility and equivalent transient voltage suppression performance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1), meeting the same regulatory and environmental standards as the SMBJ54CA-TP. Selection among these equivalents may be based on:

• Manufacturer availability and supply chain considerations
• Packaging format (Tape & Reel availability)
• Operating temperature range requirements (SMBJ54CA-TP supports -55°C to 175°C; substitutes support -55°C to 150°C)
• Inventory levels and lead time

All parts are classified as EAR99 and carry identical HTSUS codes (8541.10.0080), confirming equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can SMBJ54CA from Fairchild Semiconductor be used as a direct replacement for SMBJ54CA-TP?

A: Yes. Both parts share identical electrical specifications (54V standoff, 87.1V clamping, 6.9A peak pulse current, 600W peak power) and the same DO-214AA (SMB) package. The primary difference is the operating temperature range: Fairchild's part operates to 150°C versus 175°C for the Micro Commercial Co version. For applications within -55°C to 150°C, this substitute is electrically and mechanically equivalent.

Q: What is the difference between SMBJ54CA-13-F and SMBJ54CA-E3/52?

A: Both parts are electrically identical to the main part and each other, with matching voltage ratings, current ratings, and power dissipation. The differences are manufacturer (Diodes Incorporated versus Vishay) and packaging designation. SMBJ54CA-E3/52 is part of Vishay's TransZorb® series. Selection depends on supplier availability and procurement preferences.

Q: Are all these parts suitable for the same circuit applications?

A: Yes. All listed parts are rated for general-purpose transient voltage suppression with identical electrical performance parameters. They are interchangeable in circuits designed for 54V standoff voltage protection with 6.9A peak pulse current handling and 600W peak power dissipation.

Q: Does package designation affect PCB assembly compatibility?

A: No. All parts use the DO-214AA (SMB) surface-mount package with identical footprint and land pattern requirements. Packaging designations (such as "Tape & Reel") refer to supply format, not physical dimensions. PCB assembly equipment and reflow profiles remain unchanged across all substitutes.

Q: What compliance certifications apply to all substitute parts?

A: All parts are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is 1 (unlimited) for all parts, indicating no special storage or handling requirements.
