MP6KE7.5CAE3 Equivalent & Substitute Parts

Part Overview

The MP6KE7.5CAE3 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This bidirectional zener diode operates with a reverse standoff voltage of 6.4V and provides clamping at 11.3V maximum, with a peak pulse current rating of 53A and peak pulse power of 600W. The component is housed in a T-18 axial through-hole package and is qualified to MIL-PRF-19500 military standards.

Substitute parts are identified based on matching critical electrical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and peak pulse power rating. Package compatibility and operating temperature ranges are secondary considerations for substitution eligibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP6KE7.5CAE3 are qualified based on the following critical electrical parameters:

• Voltage - Reverse Standoff (Typ): 6.4V
• Voltage - Breakdown (Min): 7.13V
• Voltage - Clamping (Max) @ Ipp: 11.3V
• Current - Peak Pulse (10/1000µs): Minimum 53A
• Power - Peak Pulse: 600W
• Type: Zener, Bidirectional (1 channel)
• Mounting Type: Through Hole

The P6KE7.5CA manufactured by Taiwan Semiconductor Corporation meets all critical electrical parameters and is therefore classified as a direct substitute. Both components share identical voltage ratings and power dissipation specifications. The primary difference is the package format: the MP6KE7.5CAE3 uses a T-18 axial package, while the P6KE7.5CA uses a DO-204AC (DO-15) axial package. Both are through-hole axial configurations suitable for equivalent circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

The P6KE7.5CA is a qualified substitute for the MP6KE7.5CAE3 based on electrical parameter equivalence. Both components are active products with identical voltage and power ratings.

Electrical Compatibility: The P6KE7.5CA meets or exceeds all critical electrical specifications. The peak pulse current rating of 55A on the substitute exceeds the 53A requirement of the main part, providing additional margin. Voltage parameters are identical across all measured points.

Package Consideration: The substitute uses a DO-204AC (DO-15) axial package instead of the T-18 axial package. Both are through-hole axial configurations with compatible lead spacing for standard PCB layouts. Physical dimensions may differ slightly; board layout verification is necessary for space-constrained applications.

Compliance Status: The MP6KE7.5CAE3 is qualified to MIL-PRF-19500 military standards and is RoHS non-compliant. The P6KE7.5CA is ROHS3 compliant. Selection between these parts depends on application compliance requirements.

Operating Temperature: The P6KE7.5CA operates across a wider temperature range (-55 to 175°C) compared to the MP6KE7.5CAE3 (-65 to 150°C). This provides additional operational margin in high-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can the P6KE7.5CA replace the MP6KE7.5CAE3 in all applications?

A: The P6KE7.5CA is electrically equivalent and can replace the MP6KE7.5CAE3 in applications where the DO-204AC (DO-15) package footprint is compatible with the circuit board layout. Verify package dimensions and lead spacing against your PCB design before substitution.

Q: What is the difference between the T-18 and DO-204AC (DO-15) packages?

A: Both are through-hole axial packages for TVS diodes. The T-18 and DO-204AC (DO-15) differ in physical dimensions and lead diameter. Confirm that your PCB holes and component spacing accommodate the substitute package before implementation.

Q: Are the voltage ratings identical between these parts?

A: Yes. Both the MP6KE7.5CAE3 and P6KE7.5CA have identical reverse standoff voltage (6.4V), breakdown voltage (7.13V), and clamping voltage (11.3V). They are electrically interchangeable for voltage protection specifications.

Q: Does the higher peak pulse current rating on the P6KE7.5CA affect compatibility?

A: No. The P6KE7.5CA peak pulse current rating of 55A exceeds the MP6KE7.5CAE3 requirement of 53A. This provides additional safety margin and does not create compatibility issues.

Q: What compliance differences exist between these parts?

A: The MP6KE7.5CAE3 is MIL-PRF-19500 qualified and RoHS non-compliant. The P6KE7.5CA is ROHS3 compliant. Select based on your application's compliance requirements.

Q: Can I use the P6KE7.5CA in military applications requiring MIL-PRF-19500 qualification?

A: No. The P6KE7.5CA does not carry MIL-PRF-19500 qualification. Applications requiring military-grade components must use the MP6KE7.5CAE3 or equivalent MIL-qualified alternatives.

Q: Is the wider operating temperature range of the P6KE7.5CA an advantage?

A: The P6KE7.5CA operates from -55 to 175°C, compared to the MP6KE7.5CAE3 range of -65 to 150°C. The substitute provides higher temperature capability, which is beneficial for high-temperature applications. However, the main part provides lower temperature operation to -65°C.
