P6KE30C Equivalent & Substitute Parts

Part Overview

The P6KE30C is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component operates in the 25.6V reverse standoff voltage range with 600W peak pulse power handling capability in a through-hole DO-15 package. The P6KE30C is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6KE30C is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 25.6V
• Voltage - Clamping (Max) @ Ipp: 41.4V to 43.47V range
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Package / Case: DO-204AC, DO-15, Axial
• Mounting Type: Through Hole
• Applications: General Purpose

The substitute parts P6KE30CA (Diotec Semiconductor) and P6KE30CA-G (Comchip Technology) meet these electrical and mechanical requirements. Both maintain the same reverse standoff voltage, clamping voltage within acceptable tolerance, 600W power rating, and identical through-hole axial package configuration.

Parameter Comparison

Engineering Selection Recommendations

P6KE30CA (Diotec Semiconductor) is the primary substitute for the obsolete P6KE30C. This part is currently in active production status with 32,964 units in stock, ensuring supply chain continuity. The electrical parameters align within acceptable tolerance bands for general-purpose TVS applications, with clamping voltage of 41.4V compared to the original 43.47V specification.

P6KE30CA-G (Comchip Technology) serves as a secondary substitute option. This variant maintains ROHS3 compliance matching the original part and operates across the full temperature range of -55°C to 150°C. With 708 units in stock and active production status, it provides an alternative source for component procurement. The clamping voltage specification of 41.4V is equivalent to the Diotec variant.

Both substitute parts are suitable for direct replacement in through-hole PCB applications where the P6KE30C was originally specified, provided the application tolerates the lower clamping voltage of 41.4V versus the original 43.47V maximum.

Frequently Asked Questions (FAQ)

Q: Can P6KE30CA be used as a direct replacement for P6KE30C?

A: Yes. Both parts share identical reverse standoff voltage (25.6V), 600W power rating, bidirectional channel configuration, and DO-15 through-hole package. The clamping voltage of 41.4V is lower than the original 43.47V specification but remains within acceptable operating parameters for general-purpose transient suppression.

Q: What is the difference between P6KE30CA and P6KE30CA-G?

A: Both parts maintain equivalent electrical specifications for reverse standoff voltage, breakdown voltage, clamping voltage, and power rating. P6KE30CA-G is manufactured by Comchip Technology with ROHS3 compliance and operates to -55°C minimum temperature, while P6KE30CA from Diotec operates to -50°C minimum. Selection depends on supply availability and specific temperature requirements.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts use identical DO-204AC (DO-15) axial through-hole packaging. PCB footprints and mounting procedures remain unchanged during substitution.

Q: How does the clamping voltage difference affect circuit performance?

A: The substitute parts clamp at 41.4V maximum compared to the original 43.47V. This represents a 4.8% reduction in clamping voltage, providing slightly more aggressive overvoltage suppression. Applications must verify this characteristic is acceptable for their specific circuit protection requirements.

Q: What is the current-handling capability of the substitute parts?

A: P6KE30CA handles 15A peak pulse current, while P6KE30CA-G handles 14.49A peak pulse current under 10/1000µs pulse conditions. The original P6KE30C specification does not provide peak pulse current data.
