P4KE6.8A-TP Equivalent & Substitute Parts

Part Overview

The P4KE6.8A-TP is a unidirectional Zener-type transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. The device features a 5.8V reverse standoff voltage with a 10.5V maximum clamping voltage and 39A peak pulse current capability in a through-hole DO-41 package. This part is actively produced and RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4KE6.8A-TP is determined by strict equivalence across the following critical parameters:

Voltage specifications: Reverse standoff voltage of 5.8V (typical), breakdown voltage minimum of 6.45V, and clamping voltage maximum of 10.5V must be maintained within the specified tolerances.

Current and power ratings: Peak pulse current of 39A minimum and peak pulse power of 400W minimum are required to ensure adequate transient suppression capability.

Thermal performance: Operating temperature range of -55°C to 175°C (junction temperature) must be supported.

Package and mounting: Through-hole mounting in DO-41 or DO-204AL (equivalent) axial package configuration is mandatory for mechanical and electrical compatibility.

Device type and channel configuration: Zener-type unidirectional TVS diode with single channel operation.

Compliance and status: Active product status with RoHS3 compliance and REACH unaffected designation.

Parameter Comparison

Engineering Selection Recommendations

The P4KE6.8A manufactured by Taiwan Semiconductor Corporation qualifies as a direct substitute for the P4KE6.8A-TP. Both devices maintain identical voltage specifications, thermal operating range, and package configuration. The Taiwan Semiconductor Corporation variant provides equivalent or superior performance with a peak pulse current rating of 40A compared to 39A in the original part, while maintaining the same 400W peak pulse power rating.

Both parts are active products with current manufacturing status, RoHS3 compliance, and REACH unaffected designation, ensuring regulatory and supply chain continuity. The electrical parameters fall within acceptable substitution tolerances for general-purpose transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can the P4KE6.8A from Taiwan Semiconductor Corporation be used as a direct replacement for the P4KE6.8A-TP?

A: Yes. Both devices share identical voltage ratings (5.8V standoff, 10.5V clamping), thermal range (-55°C to 175°C), and through-hole DO-41 package configuration. The Taiwan Semiconductor variant provides 40A peak pulse current versus 39A, maintaining full compatibility.

Q: What are the critical parameters that determine substitution eligibility?

A: Reverse standoff voltage (5.8V), breakdown voltage (6.45V minimum), clamping voltage (10.5V maximum), peak pulse current (39A minimum), peak pulse power (400W), operating temperature range (-55°C to 175°C), and through-hole DO-41 axial package type are the determining factors.

Q: Are there package compatibility concerns between DO-41 and DO-204AL designations?

A: No. DO-41 and DO-204AL refer to the same through-hole axial package configuration. Both designations are equivalent and interchangeable for PCB mounting and electrical performance.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the P4KE6.8A-TP and P4KE6.8A are RoHS3 compliant and REACH unaffected, ensuring equivalent regulatory status for procurement and deployment.

Q: What is the significance of the 1A difference in peak pulse current rating?

A: The Taiwan Semiconductor Corporation variant (40A) provides a 2.6% margin above the original specification (39A). This represents improved performance headroom while maintaining identical clamping voltage and power dissipation characteristics, with no negative impact on substitution suitability.
