P6KE180C Equivalent & Substitute Parts

Part Overview

The P6KE180C is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage protection applications. This bidirectional zener diode operates in the DO-204AC (DO-15) axial package and provides 600W peak pulse power dissipation with a clamping voltage of 258.3V at peak pulse current. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P6KE180C is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 154V
• Voltage - Breakdown (Min): 162V minimum
• Voltage - Clamping (Max) @ Ipp: Maximum 258.3V
• Power - Peak Pulse: 600W
• Package / Case: DO-204AC (DO-15) Axial
• Mounting Type: Through Hole
• Bidirectional Channels: 1

The P6KE180CA from Fairchild Semiconductor meets these substitution criteria. Both parts share identical reverse standoff voltage (154V), equivalent power rating (600W), matching package configuration (DO-15), and through-hole mounting. The P6KE180CA maintains compatibility with the electrical performance envelope required for general-purpose transient voltage suppression applications.

Parameter Comparison

Engineering Selection Recommendations

The P6KE180CA is a direct substitute for the P6KE180C based on matching electrical specifications and package compatibility. The P6KE180CA offers the advantage of active product status, ensuring long-term availability and supply chain continuity. The lower clamping voltage (246V vs 258.3V) and higher breakdown voltage minimum (171V vs 162V) of the P6KE180CA represent tighter performance characteristics within the same functional class, suitable for applications requiring the P6KE180C electrical envelope.

For designs currently using the obsolete P6KE180C, transition to the P6KE180CA maintains functional equivalence while securing access to an actively manufactured component. Both parts comply with RoHS3 requirements and operate across overlapping temperature ranges suitable for general-purpose transient voltage suppression.

Frequently Asked Questions (FAQ)

Q: Can the P6KE180CA directly replace the P6KE180C in existing designs?

A: Yes. Both parts share identical reverse standoff voltage (154V), equivalent 600W power rating, and matching DO-15 axial package configuration. The P6KE180CA operates within the electrical performance envelope of the P6KE180C.

Q: What is the difference in clamping voltage between these parts?

A: The P6KE180C specifies a maximum clamping voltage of 258.3V, while the P6KE180CA specifies 246V. The P6KE180CA provides lower clamping voltage, which represents improved performance for transient suppression in this voltage class.

Q: Are there package compatibility concerns?

A: No. Both parts use the DO-204AC (DO-15) axial through-hole package. PCB layouts and mechanical mounting are identical.

Q: Why is the P6KE180C listed as obsolete?

A: Littelfuse Inc. has discontinued this part number. The P6KE180CA from Fairchild Semiconductor provides equivalent functionality and is actively manufactured.

Q: What is the operating temperature range difference?

A: The P6KE180C operates from -55°C to 175°C, while the P6KE180CA operates from -50°C to 175°C. For applications requiring operation below -50°C, the P6KE180C specifications must be verified against design requirements.

Q: Are both parts RoHS compliant?

A: The P6KE180C is confirmed ROHS3 compliant. RoHS compliance status for the P6KE180CA is not specified in the provided data.
