P6KE24C-B Equivalent & Substitute Parts

Part Overview

The P6KE24C-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage clamping applications. This bidirectional Zener diode operates with a reverse standoff voltage of 20.5V and provides peak pulse power handling of 600W in a through-hole DO-204AC (DO-15) 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 P6KE24C-B is determined by strict alignment of the following critical parameters:

• Voltage - Reverse Standoff (Typ): 20.5V
• Voltage - Clamping (Max) @ Ipp: Must not exceed 34.86V
• Power - Peak Pulse: 600W minimum
• Mounting Type: Through Hole
• Package / Case: DO-204AC (DO-15) Axial
• Bidirectional Channels: 1
• Type: Zener

The identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional compatibility in existing circuit designs. Both substitute parts operate within the same voltage and power parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Both P6KE24CA and P6KE24CA-B qualify as functional equivalents to the obsolete P6KE24C-B based on matching electrical specifications and package configuration.

P6KE24CA-B (Littelfuse Inc.) is the preferred substitute. It maintains identical manufacturer lineage with the original part, offers ROHS3 compliance certification, supports the full operating temperature range (-55°C ~ 175°C), and carries active product status with confirmed inventory availability. The clamping voltage of 33.2V provides improved performance margin compared to the original 34.86V specification.

P6KE24CA (Fairchild Semiconductor) provides an alternative substitute with equivalent electrical performance and identical package configuration. This part operates within a slightly reduced temperature range (-50°C ~ 175°C) and offers active product status. Selection of this alternative may be appropriate where Fairchild component qualification is established within existing supply chain protocols.

Frequently Asked Questions (FAQ)

Q: Can P6KE24CA and P6KE24CA-B be used interchangeably with P6KE24C-B?

A: Yes. Both substitute parts maintain the critical electrical parameters: 20.5V reverse standoff voltage, 600W peak pulse power, and identical DO-204AC (DO-15) axial through-hole packaging. The lower clamping voltages (33.2V versus 34.86V) represent improved performance characteristics within the same application envelope.

Q: What is the primary reason for substitution?

A: The P6KE24C-B is classified as obsolete. The identified substitutes (P6KE24CA and P6KE24CA-B) maintain active product status, ensuring long-term availability and supply chain continuity.

Q: Are there temperature range differences between the substitutes?

A: P6KE24CA-B and the original P6KE24C-B both support -55°C ~ 175°C operating range. P6KE24CA operates within -50°C ~ 175°C. For applications requiring the full -55°C lower temperature limit, P6KE24CA-B is the appropriate selection.

Q: Do the substitute parts have the same package configuration?

A: Yes. All three parts use DO-204AC (DO-15) axial through-hole packaging, ensuring direct mechanical and electrical compatibility in existing PCB layouts without modification.

Q: What compliance certifications apply to the substitute parts?

A: P6KE24CA-B carries ROHS3 compliance certification, matching the original part. P6KE24CA compliance status is not specified in available documentation.
