MP6KE110AE3 Equivalent & Substitute Parts

Part Overview

The MP6KE110AE3 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This through-hole component features a 94V reverse standoff voltage with 152V maximum clamping voltage and 3.4A peak pulse current capability. The device is classified as military-grade and qualified to MIL-PRF-19500 standards.

Substitute parts are identified when equivalent electrical performance parameters are maintained across critical specifications including reverse standoff voltage, breakdown voltage, clamping voltage, and peak pulse current ratings, while accommodating variations in packaging format and supplier availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP6KE110AE3 is determined by equivalence across the following critical electrical parameters:

• Voltage - Reverse Standoff (Typ): 94V
• Voltage - Breakdown (Min): 105V
• Voltage - Clamping (Max) @ Ipp: 152V
• Current - Peak Pulse (10/1000µs): minimum 3.4A
• Power - Peak Pulse: 600W
• Type: Zener, Unidirectional
• Mounting Type: Through Hole

The P6KE110A from Taiwan Semiconductor Corporation qualifies as a substitute part because it maintains all critical electrical parameters within the specified ranges. Variations in packaging format (T-18 versus DO-15), supplier device package designation, and RoHS compliance status do not affect functional equivalence for overvoltage protection applications where the electrical performance envelope is preserved.

Engineering Selection Recommendations

The P6KE110A qualifies as a direct electrical substitute for the MP6KE110AE3 based on matched voltage and current specifications. Selection between these parts should consider the following factors:

Compliance and Certification: The MP6KE110AE3 carries military-grade qualification (MIL-PRF-19500) and is RoHS non-compliant. The P6KE110A is ROHS3 compliant, making it suitable for applications with RoHS requirements. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Packaging and Availability: The MP6KE110AE3 is supplied in T-18 axial package format in bulk packaging with 715 units in stock. The P6KE110A is supplied in DO-15 axial package format in tape and reel packaging with 16,240 units in stock. Both are through-hole mounted components with identical electrical performance.

Peak Pulse Current: The P6KE110A provides 4A peak pulse current capability compared to the MP6KE110AE3 specification of 3.4A, representing a performance margin that does not compromise circuit compatibility.

Operating Temperature: The MP6KE110AE3 specifies -65°C to 150°C operating temperature range. Operating temperature data for the P6KE110A is not provided in the available parameters.

Frequently Asked Questions (FAQ)

Q: Can the P6KE110A replace the MP6KE110AE3 in existing designs?

A: Yes, the P6KE110A provides electrical equivalence across all critical TVS diode parameters: reverse standoff voltage (94V), breakdown voltage (105V), clamping voltage (152V), and peak pulse current (4A, exceeding the 3.4A requirement). Both are through-hole mounted unidirectional Zener devices. Package format differs (DO-15 versus T-18), but both are standard axial configurations compatible with through-hole PCB layouts.

Q: What is the difference between T-18 and DO-15 packaging?

A: T-18 and DO-15 are both axial through-hole package formats for diodes. DO-15 (DO-204AC) is the industry-standard designation for this package type. Both formats accommodate identical lead spacing and mounting procedures on through-hole PCBs. The different designations reflect manufacturer nomenclature rather than functional differences.

Q: Does the higher peak pulse current rating of the P6KE110A affect circuit compatibility?

A: No. The P6KE110A's 4A peak pulse current rating exceeds the MP6KE110AE3 specification of 3.4A. This represents additional capability that does not create incompatibility. The device will function identically in circuits designed for the lower current rating.

Q: Are there RoHS compliance implications when substituting these parts?

A: The MP6KE110AE3 is RoHS non-compliant, while the P6KE110A is ROHS3 compliant. If your application or supply chain requires RoHS compliance, the P6KE110A is the appropriate selection. If RoHS compliance is not required, both parts are functionally equivalent.

Q: What is the base product number relationship between these parts?

A: Both the MP6KE110AE3 and P6KE110A share the base product number P6KE110, indicating they are part of the same product family with identical core electrical specifications. The suffix designations (AE3 for Microchip, A for Taiwan Semiconductor) reflect manufacturer-specific packaging and qualification variations.

Q: Can I use the P6KE110A in military-grade applications requiring MIL-PRF-19500 qualification?

A: The MP6KE110AE3 carries explicit MIL-PRF-19500 qualification. The P6KE110A qualification status is not provided in the available parameters. Applications with mandatory military specification requirements should use the MP6KE110AE3 or verify P6KE110A qualification documentation with the supplier.
