P6SMB7.5A Equivalent & Substitute Parts

Part Overview

The P6SMB7.5A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 6.4V reverse standoff voltage with an 11.3V maximum clamping voltage and 54A peak pulse current capability in a compact DO-214AA (SMB) package. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Identifying equivalent substitute parts is essential for supply chain continuity, design flexibility, and procurement optimization when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6SMB7.5A is determined by strict electrical and mechanical parameter matching within the TVS diode category. The critical parameters that define substitutability are:

• Voltage - Reverse Standoff (Typ): 6.4V
• Voltage - Clamping (Max) @ Ipp: 11.3V
• Current - Peak Pulse (10/1000µs): 54A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Unidirectional Channels: 1

The P6SMB7-5A from Eaton - Electronics Division qualifies as a direct substitute because it maintains identical electrical specifications across all critical parameters, including reverse standoff voltage, clamping voltage, peak pulse current, and power dissipation. Both parts share the same DO-214AA SMB package footprint and surface-mount configuration, ensuring mechanical and thermal compatibility in existing PCB designs.

Parameter Comparison

Engineering Selection Recommendations

Both the P6SMB7.5A and P6SMB7-5A are active production components with established compliance certifications. The Bourns P6SMB7.5A carries ROHS3 Compliant status and REACH Affected designation. The Eaton P6SMB7-5A is RoHS Compliant and REACH Unaffected. Selection between these parts should be based on supply availability, procurement lead times, and specific regulatory requirements of the end application. Both parts are suitable for general-purpose transient voltage suppression in surface-mount designs requiring identical electrical performance and thermal characteristics.

Frequently Asked Questions (FAQ)
