P6KE62C Equivalent & Substitute Parts

Part Overview

The P6KE62C is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. It features a 600W peak pulse power rating and operates across a temperature range of -55°C to 175°C. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6KE62C is determined by the following critical parameters:

• Bidirectional channel configuration (1 channel required)
• Voltage - Reverse Standoff matching (53V nominal)
• Voltage - Breakdown range compatibility (55.8V minimum or higher)
• Voltage - Clamping specification (89.25V maximum or lower)
• Power - Peak Pulse rating (600W minimum)
• Package type (DO-204AC / DO-15 axial through-hole)
• Operating temperature range (-55°C to 175°C or compatible subset)
• RoHS3 compliance

The P6KE62CA from Diotec Semiconductor meets these substitution criteria across all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The P6KE62CA (Diotec Semiconductor) is a direct functional equivalent to the obsolete P6KE62C. Both devices share identical reverse standoff voltage, peak pulse power rating, package configuration, and RoHS3 compliance status. The P6KE62CA maintains active product status, ensuring ongoing availability and supply chain continuity.

The P6KE62CA exhibits a lower clamping voltage (85V versus 89.25V) and a higher minimum breakdown voltage (58.9V versus 55.8V), both of which represent improved transient suppression characteristics within the specified voltage class. The operating temperature range of the P6KE62CA (-50°C to 175°C) covers the upper portion of the P6KE62C range and is suitable for applications not requiring the extended -55°C lower limit.

Frequently Asked Questions (FAQ)

Q: Can the P6KE62CA directly replace the P6KE62C in existing designs?

A: Yes. Both devices are bidirectional TVS diodes with identical reverse standoff voltage (53V), peak pulse power (600W), and DO-15 axial through-hole packaging. The electrical characteristics of the P6KE62CA fall within acceptable substitution parameters for the P6KE62C application class.

Q: What is the significance of the clamping voltage difference (89.25V vs. 85V)?

A: The P6KE62CA's lower clamping voltage provides superior transient suppression, limiting voltage peaks to a lower threshold. This represents an improvement over the original P6KE62C specification and does not compromise compatibility in general-purpose overvoltage protection applications.

Q: Are there temperature range considerations for substitution?

A: The P6KE62CA operates from -50°C to 175°C, compared to the P6KE62C range of -55°C to 175°C. Applications requiring operation below -50°C ambient temperature should evaluate alternative sources. For standard industrial and commercial temperature ranges, the P6KE62CA is fully compatible.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the P6KE62C and P6KE62CA are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Is the DO-15 package identical between manufacturers?

A: Yes. Both devices use the DO-204AC (DO-15) axial through-hole package, ensuring mechanical and electrical compatibility in PCB layouts and circuit designs without modification.
