P6KE24C Equivalent & Substitute Parts

Part Overview

The P6KE24C 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 with a 600W peak pulse power rating and 20.5V reverse standoff voltage. The part is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P6KE24C is determined by the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 20.5V
• Voltage - Breakdown (Min): within acceptable tolerance range
• Voltage - Clamping (Max) @ Ipp: within acceptable tolerance range
• Power - Peak Pulse: 600W minimum
• Bidirectional Channels: 1
• Package / Case: DO-204AC (DO-15) axial through-hole
• Mounting Type: Through Hole
• Type: Zener diode

The P6KE24CA from Fairchild Semiconductor meets these substitution criteria with compatible electrical characteristics and identical package specifications.

Parameter Comparison

Engineering Selection Recommendations

The P6KE24CA (Fairchild Semiconductor) is the direct equivalent substitute for the obsolete P6KE24C. Both parts share identical reverse standoff voltage (20.5V), peak pulse power rating (600W), package configuration (DO-204AC/DO-15 axial), and mounting type (through-hole). The P6KE24CA is currently in active production status, ensuring long-term availability and supply chain continuity.

The P6KE24CA exhibits slightly lower clamping voltage (33.2V versus 34.86V) and higher minimum breakdown voltage (22.8V versus 21.6V), both within acceptable tolerance ranges for general-purpose TVS applications. The operating temperature range of the P6KE24CA (-50°C to 175°C) covers the majority of industrial applications, with the exception of the extended lower temperature limit of the original part (-55°C).

Frequently Asked Questions (FAQ)

Q: Can the P6KE24CA directly replace the P6KE24C in existing designs?

A: Yes. Both parts are bidirectional zener TVS diodes with identical reverse standoff voltage (20.5V), peak pulse power rating (600W), and DO-204AC (DO-15) axial package configuration. Electrical parameter variations fall within acceptable substitution tolerances for general-purpose applications.

Q: What is the primary reason for substitution?

A: The P6KE24C is obsolete. The P6KE24CA is an active production part from Fairchild Semiconductor, providing assured long-term availability and supply chain support.

Q: Are there package compatibility concerns?

A: No. Both parts use identical DO-204AC (DO-15) axial through-hole packages, ensuring mechanical and electrical compatibility in PCB designs without layout modifications.

Q: How do the clamping voltage specifications compare?

A: The P6KE24C specifies a maximum clamping voltage of 34.86V, while the P6KE24CA specifies 33.2V. Both values are within acceptable ranges for 24V nominal protection applications and represent normal manufacturing variation across different manufacturers.

Q: What is the temperature range difference?

A: The P6KE24C operates from -55°C to 175°C, while the P6KE24CA operates from -50°C to 175°C. The P6KE24CA does not support the extended lower temperature limit. Verify application requirements before substitution if operation below -50°C is required.

Q: Are both parts RoHS compliant?

A: The P6KE24C is ROHS3 compliant. RoHS compliance status for the P6KE24CA is not specified in the provided data.
