5KP5.0CA-B Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 5KP5.0CA-B is an active Littelfuse Inc. Transient Voltage Suppressor (TVS) diode designed for general-purpose overvoltage protection applications. This through-hole axial component operates across a wide temperature range (-55°C to 175°C) and provides peak pulse power dissipation of 5000W. The part is ROHS3 compliant and carries unlimited moisture sensitivity level (MSL 1), making it suitable for standard industrial and commercial environments. Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP5.0CA-B are identified based on strict electrical and mechanical parameter matching within the TVS diode category. The substitution criteria are:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Breakdown (Min): 6.4V
• Voltage - Clamping (Max) @ Ipp: 9.2V
• Power - Peak Pulse: 5000W (5kW)
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Mounting Type: Through Hole
• Type: Zener, Bidirectional (1 channel)
• RoHS Status: ROHS3 Compliant

Substitute parts may differ in packaging format (bulk vs. cut tape) and package designation (P600 vs. R-6 axial variants) while maintaining identical electrical performance and thermal specifications. These variations do not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full ROHS3 compliance with unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing and storage environments.

The 5KP5.0CA (Littelfuse) is the manufacturer-recommended equivalent, offering identical electrical specifications and P600 axial package designation with cut tape packaging format.

The 5KP5.0CA-TP (Micro Commercial Co) provides functional equivalence with matching voltage and power ratings across the operating temperature range. The R-6 axial package designation represents a mechanical variant of the through-hole axial form factor. Peak pulse current specification is not provided for this part; however, the declared 5000W peak pulse power rating at matching voltage parameters indicates equivalent transient protection capability.

Selection between these substitutes depends on packaging requirements (bulk vs. cut tape) and mechanical fit considerations within the PCB layout, as both package designations (P600 and R-6) are through-hole axial configurations.

Frequently Asked Questions (FAQ)

Q: Can 5KP5.0CA-TP replace 5KP5.0CA-B in my circuit?

A: Yes. Both parts share identical voltage ratings (5V reverse standoff, 6.4V breakdown minimum, 9.2V clamping maximum) and power dissipation (5000W peak pulse). Both are through-hole axial components rated for -55°C to 175°C operation. The R-6 package designation is a mechanical variant of the P600 axial form factor. Verify physical fit within your PCB layout before substitution.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging (5KP5.0CA-B) supplies components loose for manual handling or automated pick-and-place systems with bulk feeders. Cut tape packaging (5KP5.0CA, 5KP5.0CA-TP) supplies components on continuous tape for automated tape-fed assembly equipment. Electrical and thermal performance are identical; packaging choice depends on assembly process requirements.

Q: Are P600 and R-6 packages mechanically interchangeable?

A: Both designations refer to through-hole axial package configurations. Physical dimensions and lead spacing may vary between manufacturers. Verify mechanical compatibility with your PCB footprint design before substitution.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity). All share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Why is peak pulse current not specified for 5KP5.0CA-TP?

A: The 5KP5.0CA-TP datasheet does not provide peak pulse current (Ipp) specification. However, the declared 5000W peak pulse power rating at 9.2V clamping voltage indicates equivalent transient suppression performance. For applications requiring specific Ipp verification, consult the manufacturer's detailed datasheet.
