3KP6.0C-B Equivalent & Substitute Parts

Part Overview

The 3KP6.0C-B is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 6V reverse standoff voltage with a 10.82V maximum clamping voltage and 291.3A peak pulse current capability in a through-hole P600 axial package. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3KP6.0C-B is determined by the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 6V
• Voltage - Clamping (Max) @ Ipp: Maximum 10.82V
• Current - Peak Pulse (10/1000µs): Minimum 291.3A
• Power - Peak Pulse: Minimum 3000W
• Operating Temperature Range: -55°C to 175°C (TJ)
• Mounting Type: Through Hole
• Package / Case: Axial configuration

Substitute parts must maintain compatibility across these parameters to ensure functional equivalence in overvoltage protection circuits. The following parts meet these substitution criteria:

5KP6.0CA-B (Littelfuse Inc.) — Higher power rating (5000W) with increased peak pulse current (495.1A), maintaining voltage specifications and package compatibility.

3KP6.0CA-TP (Micro Commercial Co) — Manufacturer-recommended alternative with identical electrical performance and operating temperature range, utilizing R-6 axial package.

5KP6.0CA-TP (Micro Commercial Co) — Manufacturer-recommended alternative with higher power rating (5000W), R-6 axial package configuration.

Parameter Comparison

Engineering Selection Recommendations

5KP6.0CA-B is suitable for applications requiring higher transient energy absorption. This part maintains P600 axial package compatibility with the original 3KP6.0C-B while offering increased power dissipation (5000W vs. 3000W) and peak pulse current capability (495.1A vs. 291.3A). The part is active and ROHS3 compliant.

3KP6.0CA-TP provides direct electrical equivalence to the 3KP6.0C-B with identical power rating (3000W) and peak pulse current (291.3A). This manufacturer-recommended alternative is active and maintains full operating temperature compatibility. Package transition from P600 to R-6 axial requires mechanical verification for board layout compatibility.

5KP6.0CA-TP combines higher power capability (5000W) with manufacturer-recommended status and active product availability. This part utilizes the R-6 axial package and is ROHS3 compliant. Selection is appropriate for designs requiring enhanced transient protection margin.

Frequently Asked Questions (FAQ)

Q: Can 5KP6.0CA-B replace 3KP6.0C-B directly?

A: Yes, electrically. The 5KP6.0CA-B maintains the same 6V reverse standoff voltage and operating temperature range. The higher power rating (5000W vs. 3000W) and increased peak pulse current (495.1A vs. 291.3A) provide additional transient suppression capability. Both use P600 axial packages, enabling direct board-level substitution.

Q: What is the difference between P600 and R-6 packages?

A: Both are through-hole axial packages for TVS diodes. P600 and R-6 are different package designations. Mechanical compatibility must be verified against PCB footprint specifications before substitution.

Q: Are the Micro Commercial Co parts (3KP6.0CA-TP and 5KP6.0CA-TP) equivalent to Littelfuse parts?

A: Yes, within the specified electrical parameters. Both 3KP6.0CA-TP and 5KP6.0CA-TP are manufacturer-recommended alternatives. They maintain the 6V reverse standoff voltage and -55°C to 175°C operating temperature range. Package designation differs (R-6 vs. P600), requiring mechanical verification.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For equivalent performance with active product status, use 3KP6.0CA-TP (Micro Commercial Co). For enhanced transient protection margin, use 5KP6.0CA-B (Littelfuse) or 5KP6.0CA-TP (Micro Commercial Co).

Q: Are all substitute parts ROHS3 compliant?

A: 5KP6.0CA-B and 5KP6.0CA-TP are confirmed ROHS3 compliant. RoHS status for 3KP6.0CA-TP is not specified in available documentation.
