P6SMB47A-E3/52 Equivalent & Substitute Parts

Part Overview

The P6SMB47A-E3/52 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 40.2V reverse standoff voltage range with a 64.8V maximum clamping voltage and 9.3A peak pulse current rating. The device is housed in a DO-214AA (SMB) package and is actively produced. Equivalent and substitute parts are identified based on matching electrical characteristics and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB47A-E3/52 are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 40.2V
• Voltage - Breakdown (Min): 44.7V
• Voltage - Clamping (Max) @ Ipp: 64.8V
• Package / Case: DO-214AA or SMB equivalent
• Mounting Type: Surface Mount
• Type: Zener (Unidirectional)

Substitute parts maintain identical voltage specifications and package compatibility. Variations in peak pulse current (9.3A to 15.4A) and power dissipation (600W to 1000W) represent enhanced performance characteristics within the same voltage class. Operating temperature range and RoHS compliance status are provided for reference but do not restrict substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and meet the core electrical specifications of the P6SMB47A-E3/52. Selection among equivalents depends on application requirements:

The P6SMB47A from Eaton and SMBJP6KE47A-TP from Micro Commercial Co provide direct electrical equivalence with marginal variations in peak pulse current (9.4A versus 9.3A) and identical 600W power dissipation. Both are ROHS3 compliant.

The 1KSMB47A from Taiwan Semiconductor Corporation offers enhanced performance with 15.4A peak pulse current and 1000W power dissipation while maintaining identical voltage specifications. This part is suitable for applications requiring higher transient energy absorption within the same voltage class. ROHS3 compliance and extended operating temperature range (-55°C ~ 175°C) are provided.

All parts are housed in DO-214AA (SMB) surface mount packages and are compatible with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 1KSMB47A replace the P6SMB47A-E3/52 in all applications?

A: The 1KSMB47A maintains identical voltage specifications (40.2V reverse standoff, 64.8V clamping) and package compatibility. The higher peak pulse current (15.4A) and power dissipation (1000W) represent enhanced performance characteristics. Substitution is valid where the original design does not depend on the specific 9.3A current rating or 600W power limitation.

Q: What is the difference between P6SMB47A from Vishay and P6SMB47A from Eaton?

A: Both parts share the same part number designation and maintain identical voltage specifications and 600W power dissipation. The primary difference is manufacturer identity. Eaton's version operates across -55°C ~ 150°C, while Vishay's version extends to -65°C minimum operating temperature.

Q: Are all substitute parts in the same package?

A: All listed substitute parts use DO-214AA (SMB) surface mount packages. PCB footprints and assembly processes are compatible across all parts.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range is provided for application-specific selection. The P6SMB47A-E3/52 operates from -65°C to 150°C. Substitute parts with narrower ranges (-55°C minimum) remain electrically equivalent for applications within their specified temperature windows.

Q: What certifications apply to these parts?

A: All listed parts are ROHS3 compliant. The P6SMB47A-E3/52, SMBJP6KE47A-TP, and 1KSMB47A carry REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.
