MP6KE170CAE3 Equivalent & Substitute Parts
Part Overview
The MP6KE170CAE3 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose voltage transient protection applications. This bidirectional Zener-type TVS diode features a 145V reverse standoff voltage and 234V maximum clamping voltage, with a peak pulse current rating of 2.6A and 600W peak pulse power dissipation. The device is housed in a T-18 axial through-hole package and is qualified to MIL-PRF-19500 military standards. The part maintains active product status and is available in bulk packaging with 807 units currently in stock. Substitute parts are identified to address packaging preferences, compliance requirements, or inventory availability while maintaining equivalent electrical performance.

Substitute Part Grouping Explanation
Substitution of the MP6KE170CAE3 is determined by equivalence across the following critical electrical parameters:
- Voltage - Reverse Standoff (Typ): 145V
- Voltage - Clamping (Max) @ Ipp: 234V
- Current - Peak Pulse (10/1000µs): 2.6A
- Power - Peak Pulse: 600W
- Bidirectional Channels: 1
- Type: Zener
- Mounting Type: Through Hole
The substitute part P6KE170CA, manufactured by Taiwan Semiconductor Corporation, maintains electrical equivalence across all critical parameters. The primary difference is the package configuration: the substitute uses DO-15 (DO-204AC) axial packaging instead of the T-18 package. Both parts share the same base product number (P6KE170) and are classified as general-purpose TVS diodes. The substitute part is available in Tape & Reel packaging and carries RoHS3 compliance, whereas the main part is RoHS non-compliant.

Engineering Selection Recommendations
MP6KE170CAE3 (Microchip Technology) is the appropriate selection when:
- Military-grade qualification per MIL-PRF-19500 is required
- T-18 axial package configuration is mandated by PCB design or assembly specifications
- Bulk packaging format is preferred for high-volume manufacturing operations
- RoHS non-compliance is acceptable within the application environment
P6KE170CA (Taiwan Semiconductor Corporation) is the appropriate selection when:
- RoHS3 compliance is a mandatory requirement for the end application or supply chain
- DO-15 axial package configuration is compatible with PCB layout and assembly processes
- Tape & Reel packaging format is required for automated pick-and-place assembly
- Military qualification is not a specified requirement
- Higher inventory availability (1420 units) is advantageous for procurement timelines
Both parts deliver identical electrical performance for transient voltage suppression applications within the specified operating parameters. Selection between them is determined by packaging, compliance, and qualification requirements rather than electrical functionality.
Frequently Asked Questions (FAQ)
Q: Can P6KE170CA be used as a direct replacement for MP6KE170CAE3 in existing designs?
A: Electrical substitution is valid. However, physical compatibility depends on PCB footprint design. The T-18 package and DO-15 package have different physical dimensions and lead spacing. PCB layout verification is required before implementation.
Q: What is the difference between T-18 and DO-15 packages?
A: Both are axial through-hole packages for TVS diodes. T-18 is a larger package format, while DO-15 (DO-204AC) is a smaller standard package. The choice affects PCB board space, assembly compatibility, and component handling in manufacturing.
Q: Does the RoHS3 compliance of P6KE170CA affect electrical performance?
A: No. RoHS3 compliance relates to material composition and environmental restrictions, not electrical characteristics. Both parts maintain identical voltage, current, and power ratings.
Q: Why does the MP6KE170CAE3 have MIL-PRF-19500 qualification while P6KE170CA does not?
A: Military qualification is a manufacturing and testing certification specific to Microchip Technology's production process. It does not indicate superior electrical performance but rather compliance with military procurement standards. Selection depends on application requirements.
Q: Are there operating temperature differences between the two parts?
A: The MP6KE170CAE3 specifies an operating temperature range of -65°C to 150°C (TJ). The P6KE170CA operating temperature range is not provided in the available data. Verify temperature specifications with the manufacturer if operation outside standard industrial ranges is required.
Q: What packaging format should be selected for automated assembly?
A: Tape & Reel (TR) packaging, as provided with the P6KE170CA, is standard for automated pick-and-place assembly equipment. Bulk packaging, as provided with the MP6KE170CAE3, is typically used for manual assembly or high-volume tape-fed operations.
Q: Are both parts suitable for general-purpose transient voltage protection?
A: Yes. Both the MP6KE170CAE3 and P6KE170CA are classified for general-purpose applications and provide equivalent transient suppression performance at 145V standoff and 234V clamping voltage levels.
