SMCJ54A-13 Equivalent & Substitute Parts

Part Overview

The SMCJ54A-13 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose transient protection applications. This surface-mount component operates with a 54V reverse standoff voltage and provides 87.1V maximum clamping voltage at peak pulse current. The part is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity. Alternative sources and packaging configurations provide functionally compatible options while maintaining electrical performance within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of TVS diodes is determined by electrical parameter compatibility within defined tolerances and mechanical compatibility. The following criteria establish valid substitution relationships for the SMCJ54A-13:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 54V
• Voltage - Breakdown (Min): 60V
• Voltage - Clamping (Max) @ Ipp: 87.1V (±tolerance)
• Current - Peak Pulse (10/1000µs): ≥17.2A
• Power - Peak Pulse: 1500W
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Type: Zener
• Unidirectional Channels: 1
• Operating Temperature: -55°C minimum to 150°C minimum

Packaging Variants: Cut Tape (CT) and Tape & Reel (TR) configurations are mechanically interchangeable for the same electrical device, differing only in supply format.

Manufacturer Variants: Parts from different manufacturers meeting identical electrical specifications and package requirements are classified as equivalent substitutes.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Packaging Variant): SMCJ54A-13-F is the direct equivalent of SMCJ54A-13, differing only in packaging format (Tape & Reel versus Cut Tape). Both are manufactured by Diodes Incorporated with identical electrical specifications. Selection between these variants depends on assembly process requirements and inventory management practices.

Full Electrical Equivalents: SMCJ54A (Meritek) and SMCJ54A-E3/57T (Vishay) meet all electrical parameters of the SMCJ54A-13 with peak pulse current specifications within 0.02A to 0.1A of the original part. Both components are RoHS3 compliant and carry unlimited MSL rating. These parts are suitable for direct substitution in applications where the specified electrical performance is required.

Extended Temperature Capability: SMCJ54A-TP (Micro Commercial Co) provides identical electrical performance with extended upper operating temperature to 175°C, compared to 150°C for the SMCJ54A-13. This part is applicable in thermal environments exceeding 150°C junction temperature.

Parameter Deviation: SMCJ54 (Taiwan Semiconductor Corporation) exhibits higher clamping voltage (96.3V versus 87.1V) and lower peak pulse current (16A versus 17.2A). This part is not recommended as a direct substitute where the specified 87.1V clamping voltage is a design requirement.

All substitute parts listed maintain RoHS3 compliance, REACH unaffected status, and MSL 1 rating consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can SMCJ54A-13-F be used as a direct replacement for SMCJ54A-13?

A: Yes. SMCJ54A-13-F is manufactured by Diodes Incorporated with identical electrical specifications. The only difference is packaging format: SMCJ54A-13-F is supplied in Tape & Reel format while SMCJ54A-13 is supplied in Cut Tape format. Both are mechanically and electrically compatible.

Q: What is the significance of the clamping voltage difference between SMCJ54A-13 and SMCJ54?

A: The SMCJ54A-13 specifies 87.1V maximum clamping voltage, while SMCJ54 specifies 96.3V. This 9.2V difference affects transient suppression performance. The SMCJ54 is not recommended where the 87.1V specification is a design requirement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (SMCJ54A-13-F, SMCJ54, SMCJ54A, SMCJ54A-E3/57T, and SMCJ54A-TP) are RoHS3 compliant with REACH unaffected status, matching the compliance profile of the original SMCJ54A-13.

Q: Which substitute part has the highest operating temperature rating?

A: SMCJ54A-TP (Micro Commercial Co) is rated to 175°C junction temperature, compared to 150°C for the SMCJ54A-13. This extended rating applies when thermal performance is a design consideration.

Q: Can I substitute based on packaging alone?

A: No. Packaging format (Cut Tape, Tape & Reel) is a supply chain variable only. Electrical parameters must match the application requirements. SMCJ54A-13-F differs from SMCJ54A-13 only in packaging; all other substitute parts require verification that their electrical specifications satisfy circuit design requirements.

Q: What does MSL 1 (Unlimited) mean for these components?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All listed substitute parts carry this rating, eliminating moisture sensitivity as a substitution constraint.

Q: Are there any substitutes with lower peak pulse current than 17.2A?

A: Yes. SMCJ54 (Taiwan Semiconductor Corporation) is rated at 16A peak pulse current, which is 1.2A lower than the SMCJ54A-13 specification. This part is not recommended where the 17.2A specification is required.
