MP6KE75AE3 Equivalent & Substitute Parts

Part Overview

The MP6KE75AE3 is an active-status Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology. This unidirectional zener-type device is designed for general-purpose transient voltage suppression applications in through-hole configurations. The part operates across a temperature range of -65°C to 150°C and carries military-grade qualification under MIL-PRF-19500. Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and sourcing options while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Substitute Part Grouping Explanation

Substitute parts for the MP6KE75AE3 are identified based on electrical parameter equivalence and mechanical compatibility. The substitution logic is based on the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 64.1V
• Voltage - Breakdown (Min): 71.3V
• Voltage - Clamping (Max) @ Ipp: 103V
• Current - Peak Pulse (10/1000µs): within acceptable tolerance of 5.8A
• Power - Peak Pulse: 600W
• Type: Zener, Unidirectional

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package Style: Axial configuration
• Applications: General Purpose

The P6KE75A from Fairchild Semiconductor meets these electrical and mechanical criteria. Both devices share identical voltage specifications (reverse standoff, breakdown, and clamping voltages) and equivalent peak pulse current ratings (6.1A versus 5.8A). Both are through-hole mounted axial devices rated for 600W peak pulse power and general-purpose transient suppression applications.

Engineering Selection Recommendations

MP6KE75AE3 (Microchip Technology):

• Primary selection for applications requiring military-grade qualification under MIL-PRF-19500
• Specified operating temperature range: -65°C to 150°C
• RoHS non-compliant status
• Recommended for designs with established Microchip component qualification

P6KE75A (Fairchild Semiconductor):

• Suitable substitute where military qualification is not required
• Extended upper operating temperature limit: 175°C (versus 150°C for MP6KE75AE3)
• Equivalent electrical performance across all critical voltage and current parameters
• Package style (DO-15/DO-204AC) provides mechanical compatibility with axial through-hole mounting
• Recommended for general-purpose applications where temperature range and qualification requirements align with design specifications

Both devices are active-status products with equivalent electrical characteristics. Selection between them is determined by application-specific requirements regarding military qualification, operating temperature range, and component sourcing strategy.

Frequently Asked Questions (FAQ)

Q: Can the P6KE75A directly replace the MP6KE75AE3 in all applications?

A: The P6KE75A is electrically equivalent to the MP6KE75AE3 across all critical voltage and current parameters. However, substitution is application-dependent. If military qualification under MIL-PRF-19500 is required, the MP6KE75AE3 must be used. If the application operates above 150°C, the P6KE75A's extended temperature rating to 175°C may be advantageous. Both devices are through-hole axial-mounted and mechanically compatible.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: Voltage - Reverse Standoff (64.1V), Voltage - Breakdown (71.3V), Voltage - Clamping (103V), Current - Peak Pulse (5.8A nominal), and Power - Peak Pulse (600W). Both the MP6KE75AE3 and P6KE75A meet these specifications. The P6KE75A provides slightly higher peak pulse current (6.1A), which is within acceptable tolerance.

Q: Are there package differences between these devices?

A: The MP6KE75AE3 uses T-18 axial packaging, while the P6KE75A uses DO-15 (DO-204AC) axial packaging. Both are through-hole mounted axial configurations and are mechanically compatible for standard PCB layouts. Physical dimensions may vary slightly; verify against specific PCB footprint requirements.

Q: What is the significance of the operating temperature range difference?

A: The MP6KE75AE3 operates from -65°C to 150°C, while the P6KE75A operates from -50°C to 175°C. The MP6KE75AE3 provides lower temperature operation (-65°C versus -50°C), while the P6KE75A provides higher temperature operation (175°C versus 150°C). Select based on application temperature requirements.

Q: Does military qualification affect substitution decisions?

A: Yes. The MP6KE75AE3 carries military-grade qualification under MIL-PRF-19500. If design specifications or procurement requirements mandate military qualification, the MP6KE75AE3 is the required selection. The P6KE75A does not carry this qualification and is suitable only for applications where military qualification is not specified.

Q: Are both devices RoHS compliant?

A: The MP6KE75AE3 is RoHS non-compliant. RoHS compliance status for the P6KE75A is not specified in the provided parameters. Verify RoHS compliance requirements with the specific application and procurement standards before substitution.
