MP6KE36AE3 Equivalent & Substitute Parts

Part Overview

The MP6KE36AE3 is an active-status transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This unidirectional zener-type TVS diode operates with a reverse standoff voltage of 30.8V and provides clamping protection at 49.9V with a peak pulse current rating of 12A. The device is packaged in a T-18 axial through-hole configuration and is qualified to MIL-PRF-19500 military standards.

Substitute parts are identified to address inventory availability, alternative sourcing requirements, or specific application constraints while maintaining electrical and mechanical compatibility within the defined parameter ranges for this TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP6KE36AE3 are qualified based on the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 30.8V
• Voltage - Breakdown (Min): 34.2V
• Voltage - Clamping (Max) @ Ipp: 49.9V
• Current - Peak Pulse (10/1000µs): minimum 12A
• Power - Peak Pulse: 600W
• Type: Zener, Unidirectional (1 channel)
• Applications: General Purpose

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package Style: Axial configuration

The substitute part P6KE36A meets these criteria with equivalent voltage specifications and clamping characteristics. The peak pulse current of 12.6A exceeds the minimum requirement of 12A, and the 600W peak pulse power rating matches the main part specification. Both devices are through-hole mounted with axial package configurations, ensuring mechanical interchangeability in circuit board layouts designed for the MP6KE36AE3.

Engineering Selection Recommendations

MP6KE36AE3 (Microchip Technology):

• Primary selection for applications requiring MIL-PRF-19500 military qualification
• Specified for military-grade applications with formal qualification documentation
• Operating temperature range: -65°C to 150°C (TJ)
• RoHS non-compliant status; REACH Unaffected
• Recommended for defense, aerospace, and military-specification system designs

P6KE36A (Fairchild Semiconductor):

• Suitable for general-purpose commercial and industrial applications
• Equivalent electrical performance with higher peak pulse current rating (12.6A vs. 12A)
• Extended upper operating temperature limit: 175°C (TJ) versus 150°C for the main part
• Axial through-hole package (DO-15/DO-204AC) compatible with T-18 mounting footprints
• Recommended for applications where military qualification is not required and extended temperature operation is beneficial

Both parts maintain active product status and are suitable for general-purpose transient voltage suppression. Selection between them depends on qualification requirements and operating temperature constraints specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the P6KE36A directly replace the MP6KE36AE3 in all applications?

A: The P6KE36A is electrically compatible with the MP6KE36AE3 for general-purpose transient voltage suppression. However, if the application requires MIL-PRF-19500 military qualification, the MP6KE36AE3 must be used. For non-military applications, the P6KE36A is a suitable substitute with equivalent clamping voltage and higher peak pulse current capability.

Q: Are there package compatibility concerns between T-18 and DO-15 axial packages?

A: Both the T-18 (MP6KE36AE3) and DO-15 (P6KE36A) are axial through-hole packages with compatible lead spacing and mounting characteristics. They are mechanically interchangeable in circuit board designs that accommodate standard axial component footprints. Verify specific PCB layout requirements for your application.

Q: What is the significance of the higher peak pulse current rating on the P6KE36A?

A: The P6KE36A is rated for 12.6A peak pulse current compared to 12A for the MP6KE36AE3. This higher rating provides additional margin for transient suppression without exceeding device limits. Both devices maintain the same 600W peak pulse power rating and 49.9V clamping voltage, ensuring equivalent protection performance.

Q: How do the operating temperature ranges differ between these parts?

A: The MP6KE36AE3 operates from -65°C to 150°C (TJ), while the P6KE36A operates from -50°C to 175°C (TJ). The P6KE36A provides extended upper temperature capability. For applications requiring operation below -50°C, the MP6KE36AE3 is required.

Q: What compliance and qualification differences exist between these parts?

A: The MP6KE36AE3 is qualified to MIL-PRF-19500 military standards and carries a military-grade designation. The P6KE36A is a commercial-grade component without military qualification. Both are RoHS non-compliant and REACH Unaffected. Select based on whether military qualification is a system requirement.

Q: Are the voltage specifications identical between these substitute parts?

A: Yes. Both parts share identical reverse standoff voltage (30.8V), breakdown voltage (34.2V minimum), and clamping voltage (49.9V maximum). These matching specifications ensure equivalent transient suppression performance in circuit protection applications.
