MP6KE30AE3 Equivalent & Substitute Parts

Part Overview

The MP6KE30AE3 is an active Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, classified as a unidirectional Zener-type device. This component is designed for general-purpose transient voltage suppression applications in through-hole configurations. The part operates across a military-grade specification (MIL-PRF-19500) with an operating temperature range of -65°C to 150°C. Identification of equivalent and substitute parts becomes necessary when addressing inventory constraints, packaging format requirements, compliance certifications, or supply chain optimization while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP6KE30AE3 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - Reverse Standoff (Typ): 25.6V
• Voltage - Breakdown (Min): 28.5V
• Voltage - Clamping (Max) @ Ipp: 41.4V
• Current - Peak Pulse (10/1000µs): 14.4A minimum
• Power - Peak Pulse: 600W
• Type: Zener, Unidirectional
• Mounting Type: Through Hole

The substitute part P6KE30A, manufactured by Taiwan Semiconductor Corporation, meets all critical electrical parameters with a peak pulse current of 14.5A, which exceeds the minimum requirement. Both parts share the same base product number (P6KE30) and voltage specifications. The primary difference lies in packaging format (T-18 Axial versus DO-15 Axial) and compliance certifications. The P6KE30A is available in Cut Tape packaging with higher inventory availability and RoHS3 compliance, whereas the MP6KE30AE3 is supplied in Bulk packaging with military-grade qualification.

Engineering Selection Recommendations

MP6KE30AE3 Selection Criteria: Select the MP6KE30AE3 when military-grade qualification per MIL-PRF-19500 is a mandatory requirement. This part is appropriate for defense, aerospace, or other applications with explicit military specification compliance. The Bulk packaging format suits high-volume production environments. The part maintains active product status with 928 units in stock.

P6KE30A Selection Criteria: Select the P6KE30A when RoHS3 compliance is required and military qualification is not mandated. This substitute provides identical electrical performance with a 0.1A higher peak pulse current rating, offering additional design margin. The DO-15 package format is widely supported in standard PCB designs. The Cut Tape packaging format is suitable for automated assembly processes. Significantly higher inventory availability (25,200 units) supports rapid procurement. This part is appropriate for commercial and industrial applications where environmental compliance takes precedence over military certification.

Substitution Feasibility: Direct substitution is electrically and mechanically feasible between these two parts. The primary consideration is compliance certification alignment with application requirements. Physical package dimensions differ between T-18 and DO-15 formats; PCB layout verification is necessary prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can P6KE30A directly replace MP6KE30AE3 in all applications?

A: Electrical substitution is valid based on identical voltage specifications and compatible current ratings. However, physical package differences (T-18 versus DO-15) require PCB layout verification. Compliance requirements must be evaluated: if MIL-PRF-19500 qualification is mandatory, the MP6KE30AE3 is required. If RoHS3 compliance is mandatory, the P6KE30A is required.

Q: What are the physical package differences between T-18 and DO-15?

A: Both are axial through-hole packages with different dimensional specifications. T-18 and DO-15 have different lead spacing and body dimensions. PCB footprint compatibility must be confirmed before substitution.

Q: Are the electrical performance characteristics identical?

A: Voltage specifications are identical across all critical parameters. Peak pulse current differs slightly: MP6KE30AE3 is rated at 14.4A while P6KE30A is rated at 14.5A. This 0.1A difference represents a 0.7% variance and does not affect functional compatibility.

Q: What is the significance of the RoHS compliance difference?

A: MP6KE30AE3 is RoHS non-compliant, while P6KE30A is RoHS3 compliant. RoHS3 compliance is required for products sold in the European Union and for many commercial applications. Selection depends on end-market and regulatory requirements.

Q: Why does the operating temperature range differ between parts?

A: MP6KE30AE3 specifies -65°C to 150°C operating temperature. P6KE30A does not provide an operating temperature specification in the available data. For applications requiring confirmed temperature performance across the full military range, the MP6KE30AE3 is the appropriate selection.

Q: What packaging formats are available?

A: MP6KE30AE3 is supplied in Bulk packaging. P6KE30A is supplied in Cut Tape (CT) format. Bulk packaging is typical for high-volume direct component procurement, while Cut Tape format is optimized for automated assembly line integration.

Q: How do inventory levels affect selection?

A: MP6KE30AE3 has 928 units in stock. P6KE30A has 25,200 units in stock. Higher inventory availability of P6KE30A supports shorter lead times and reduced supply chain risk for non-military applications.
