MP6KE200AE3 Equivalent & Substitute Parts

Part Overview

The MP6KE200AE3 is an active Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose voltage transient protection applications. This unidirectional zener-type TVS diode operates with a reverse standoff voltage of 171V and provides clamping protection at 274V maximum. The device is qualified to MIL-PRF-19500 military standards and is currently in active production status with 905 units in stock.

Equivalent and substitute parts are identified to provide design flexibility when the primary part number is unavailable, when alternative packaging configurations are required, or when sourcing from multiple manufacturers is necessary to meet supply chain requirements.

Substitute Part Grouping Explanation

Substitute parts for the MP6KE200AE3 are identified based on electrical parameter equivalence within the allowed tolerance ranges for TVS diode applications. The substitution logic is based on the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 171V
• Voltage - Breakdown (Min): 190V
• Voltage - Clamping (Max) @ Ipp: 274V
• Current - Peak Pulse (10/1000µs): 2.2A
• Power - Peak Pulse: 600W
• Type: Zener, Unidirectional (1 channel)
• Applications: General Purpose

Mechanical Compatibility Criteria:

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

The P6KE200A from Fairchild Semiconductor meets all electrical parameter requirements and operates as a direct functional equivalent. While the package designation differs (DO-15/DO-204AC versus T-18), both are through-hole axial packages suitable for identical circuit board layouts and soldering processes.

Engineering Selection Recommendations

MP6KE200AE3 (Microchip Technology):

• Primary selection for applications requiring MIL-PRF-19500 military qualification
• Recommended when military-grade certification is a design requirement
• Suitable for temperature-constrained applications within the -65°C to 150°C range
• RoHS non-compliant status must be evaluated against project compliance requirements

P6KE200A (Fairchild Semiconductor):

• Direct electrical equivalent with identical voltage and current ratings
• Extended operating temperature range (-50°C to 175°C) provides additional thermal margin for high-temperature applications
• Through-hole axial package (DO-15/DO-204AC) is mechanically compatible with T-18 footprints
• Suitable for general-purpose applications where military qualification is not required
• Higher inventory availability (165,200 units) supports rapid procurement

Both parts share identical electrical performance characteristics and are suitable for interchangeable use in general-purpose transient voltage suppression circuits where the specific package designation does not impose physical constraints.

Frequently Asked Questions (FAQ)

Q: Can the P6KE200A replace the MP6KE200AE3 in all applications?

A: The P6KE200A is electrically equivalent and functionally interchangeable for general-purpose TVS applications. The primary consideration is military qualification: if MIL-PRF-19500 certification is required, the MP6KE200AE3 must be used. For non-military applications, the P6KE200A provides identical electrical performance.

Q: Are the T-18 and DO-15 packages physically compatible?

A: Both T-18 and DO-15 are through-hole axial package styles with identical lead spacing and soldering characteristics. They are mechanically compatible for standard printed circuit board layouts. Physical dimensions should be verified against specific board design constraints if space is limited.

Q: What is the difference in operating temperature ranges between these parts?

A: The MP6KE200AE3 operates from -65°C to 150°C (TJ), while the P6KE200A operates from -50°C to 175°C (TJ). The P6KE200A provides a wider temperature range, particularly beneficial for high-temperature environments. For applications operating below -50°C, the MP6KE200AE3 is required.

Q: Do both parts have the same voltage ratings?

A: Yes. Both parts have identical voltage specifications: 171V reverse standoff, 190V minimum breakdown, and 274V maximum clamping voltage at peak pulse current. They are rated for the same 2.2A peak pulse current and 600W peak pulse power.

Q: What is the significance of the MIL-PRF-19500 qualification on the MP6KE200AE3?

A: MIL-PRF-19500 is a military performance specification for semiconductor devices. This qualification indicates the MP6KE200AE3 meets stringent military reliability, testing, and quality standards. It is required for defense, aerospace, and other military-grade applications. The P6KE200A does not carry this certification.

Q: Are there any RoHS compliance differences between these parts?

A: The MP6KE200AE3 is RoHS non-compliant. The RoHS status of the P6KE200A is not specified in the provided data. RoHS compliance requirements should be verified with the supplier before final part selection for applications subject to RoHS regulations.
