SMBJ54CA-13 Equivalent & Substitute Parts

Part Overview

The SMBJ54CA-13 is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, 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. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ54CA-13 is determined by the following critical 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 or unidirectional)

All identified substitute parts maintain identical electrical specifications across voltage and current ratings. Packaging remains consistent with SMB/DO-214AA form factor. Variations in operating temperature range, RoHS compliance status, and product availability are noted but do not affect electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

SMBJ54CA-13-F (Diodes Incorporated): Direct manufacturer equivalent with identical electrical specifications and same operating temperature range. Offers ROHS3 compliance and active product status. Tape & Reel packaging provides production-volume compatibility. Recommended as primary substitute for direct replacement.

SMBJ54CA-TP (Micro Commercial Co): Functionally equivalent with extended operating temperature range (-55°C ~ 175°C). ROHS3 compliant and actively produced. Suitable for applications requiring higher thermal margin. Tape & Reel packaging standard.

SMBJ54A-TP (Micro Commercial Co): Manufacturer-recommended alternative with unidirectional Zener configuration versus the original bidirectional design. Extended operating temperature range (-55°C ~ 175°C) and ROHS3 compliance. Selection requires confirmation that unidirectional operation meets circuit requirements.

SMBJ54CA (Fairchild Semiconductor): Manufacturer-recommended option with highest inventory availability (140300 Pcs). Bidirectional Zener type matches original specification. Operating temperature range matches original (-55°C ~ 150°C). RoHS compliance status not specified in provided data.

Frequently Asked Questions (FAQ)

Q: Can SMBJ54CA-13 be directly replaced with SMBJ54CA-13-F?

A: Yes. Both parts are manufactured by Diodes Incorporated with identical electrical specifications (54V standoff, 87.1V clamping, 6.9A peak pulse current, 600W peak power). The primary difference is packaging format (bulk versus Tape & Reel) and RoHS compliance status. SMBJ54CA-13-F is the active production equivalent.

Q: What is the difference between bidirectional and unidirectional TVS diodes?

A: Bidirectional TVS diodes (SMBJ54CA-13, SMBJ54CA-13-F, SMBJ54CA-TP, SMBJ54CA) protect against overvoltage in both polarities. Unidirectional TVS diodes (SMBJ54A-TP) protect in one direction only. Selection depends on circuit polarity requirements. Verify circuit topology before substituting with unidirectional variants.

Q: Does operating temperature range affect substitution compatibility?

A: Operating temperature range does not affect electrical interchangeability at standard operating conditions. SMBJ54CA-TP and SMBJ54A-TP offer extended range (-55°C ~ 175°C) versus the original (-55°C ~ 150°C). Extended range provides additional thermal margin but is not required for direct substitution in applications operating within the original temperature specification.

Q: Are all substitute parts RoHS compliant?

A: SMBJ54CA-13-F, SMBJ54CA-TP, and SMBJ54A-TP are ROHS3 compliant. The original SMBJ54CA-13 is RoHS non-compliant. SMBJ54CA (Fairchild) RoHS status is not specified in provided data. Verify RoHS requirements for your application before final selection.

Q: Can I use SMBJ54CA-13 in production if inventory is available?

A: The original SMBJ54CA-13 is discontinued at DiGi Electronics. While 1071 Pcs remain in stock, long-term production continuity cannot be assured. Active alternatives (SMBJ54CA-13-F, SMBJ54CA-TP, SMBJ54A-TP, SMBJ54CA) are recommended for new designs and ongoing production.

Q: What packaging format should I specify for production assembly?

A: Tape & Reel (TR) packaging is standard for automated surface-mount assembly. SMBJ54CA-13-F, SMBJ54CA-TP, and SMBJ54A-TP are available in Tape & Reel format. SMBJ54CA packaging format is not specified in provided data; verify with supplier before procurement.
