P4SMA5.0A BK Equivalent & Substitute Parts

Part Overview

The P4SMA5.0A BK is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Central Semiconductor Corp, designed for general-purpose overvoltage protection applications. This component features a 5V reverse standoff voltage with a 9.2V maximum clamping voltage and 44.6A peak pulse current capability in a surface-mount SMA package.

The P4SMA5.0A BK is classified as obsolete. Identifying qualified substitute components ensures design continuity and maintains supply chain reliability for applications requiring equivalent transient voltage suppression performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA5.0A BK is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 5V
• Voltage - Breakdown (Min): 6.4V
• Voltage - Clamping (Max) @ Ipp: 9.2V
• Current - Peak Pulse (10/1000µs): 44.6A
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Type: Zener, Unidirectional

The SMAJ5.0A-13-F from Diodes Incorporated meets all specified electrical and mechanical parameters, providing direct functional equivalence for the obsolete P4SMA5.0A BK.

Parameter Comparison

Engineering Selection Recommendations

The SMAJ5.0A-13-F is the qualified substitute for the P4SMA5.0A BK based on the following factors:

• Complete electrical parameter equivalence across all critical voltage and current specifications
• Identical package and mounting configuration (DO-214AC, SMA surface mount)
• Active product status with established supply chain availability (35,100 units in stock)
• RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements
• Identical operating temperature range (-55°C ~ 150°C)

The substitute component is suitable for direct replacement in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the SMAJ5.0A-13-F replace the P4SMA5.0A BK in existing PCB designs?

A: Yes. Both components share identical electrical specifications (5V standoff, 9.2V clamping, 44.6A peak pulse) and the same DO-214AC SMA package footprint, enabling direct PCB substitution without layout changes.

Q: What is the primary reason for substituting the P4SMA5.0A BK?

A: The P4SMA5.0A BK is classified as obsolete. The SMAJ5.0A-13-F provides equivalent performance with active product status and reliable supply availability.

Q: Are there any compliance differences between the two parts?

A: The SMAJ5.0A-13-F carries RoHS3 compliance and REACH unaffected status. Both components share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: What packaging options are available for the SMAJ5.0A-13-F?

A: The SMAJ5.0A-13-F is supplied in Cut Tape (CT) and Digi-Reel® packaging formats.

Q: Are the thermal characteristics identical?

A: Yes. Both components operate across the same temperature range (-55°C ~ 150°C junction temperature) with identical power dissipation ratings (400W peak pulse).
