MP6KE16AE3 Equivalent & Substitute Parts

Part Overview

The MP6KE16AE3 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This component features a 13.6V reverse standoff voltage with a 22.5V maximum clamping voltage and 27A peak pulse current capability in a T-18 axial through-hole package. The device is classified as military-grade and qualified to MIL-PRF-19500 standards. Substitute parts are identified to provide equivalent electrical performance with potential variations in packaging, thermal characteristics, and compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the MP6KE16AE3 are identified based on electrical parameter equivalence within the TVS diode category. The primary substitution criteria are:

Electrical Equivalence Parameters:

• Voltage - Reverse Standoff (Typ): 13.6V
• Voltage - Breakdown (Min): 15.2V
• Voltage - Clamping (Max) @ Ipp: 22.5V
• Current - Peak Pulse (10/1000µs): ≥27A
• Power - Peak Pulse: 600W
• Type: Zener, Unidirectional (1 channel)
• Applications: General Purpose

Acceptable Variations:

• Package / Case: Different through-hole axial packages (T-18, DO-15/DO-204AC)
• Operating Temperature Range: Extended or equivalent ranges
• Compliance Status: RoHS and REACH certifications may differ
• Manufacturer: Alternative qualified suppliers

The P6KE16A from Diotec Semiconductor meets all electrical equivalence criteria and is classified as a direct substitute.

Engineering Selection Recommendations

MP6KE16AE3 (Microchip Technology):

• Select this part for applications requiring military-grade qualification and MIL-PRF-19500 compliance
• Suitable for defense, aerospace, and high-reliability industrial applications
• Operating temperature range: -65°C to 150°C
• RoHS non-compliant status requires verification against procurement specifications

P6KE16A (Diotec Semiconductor):

• Select this part for commercial and industrial applications where RoHS3 compliance is required
• Extended operating temperature range: -50°C to 175°C provides thermal margin in high-temperature environments
• Peak pulse current rating of 28A exceeds the minimum requirement of 27A
• DO-15 package offers standard through-hole compatibility with alternative PCB layouts
• Active product status with higher inventory availability (10,100 pcs vs. 806 pcs)

Both parts maintain identical critical electrical parameters: 13.6V reverse standoff, 15.2V minimum breakdown, and 22.5V maximum clamping voltage. Selection between these substitutes depends on compliance requirements, thermal operating conditions, and package form factor constraints.

Frequently Asked Questions (FAQ)

Q: Can the P6KE16A directly replace the MP6KE16AE3 in all applications?

A: Electrical substitution is valid for general-purpose overvoltage protection circuits. The P6KE16A meets all core voltage and current specifications. However, applications requiring military-grade qualification (MIL-PRF-19500) must retain the MP6KE16AE3. Package differences (T-18 vs. DO-15) require PCB layout verification for mechanical fit and thermal management.

Q: What is the significance of the different operating temperature ranges?

A: The MP6KE16AE3 operates from -65°C to 150°C, while the P6KE16A operates from -50°C to 175°C. The P6KE16A provides extended high-temperature capability, beneficial for applications in elevated ambient conditions. The MP6KE16AE3 extends to lower temperatures, required for cryogenic or arctic environments. Select based on actual application temperature requirements.

Q: Are there package compatibility concerns between T-18 and DO-15?

A: Both packages are axial through-hole configurations with different physical dimensions. T-18 (T-package) and DO-15 (DO-204AC) have different lead spacing and body lengths. PCB footprint redesign is required for package substitution. Verify mechanical clearance and thermal dissipation characteristics for the target application.

Q: Why does the P6KE16A have a higher peak pulse current rating (28A vs. 27A)?

A: The 28A rating for the P6KE16A represents the manufacturer's specification for that device variant. Both parts maintain the same 600W peak pulse power rating and identical voltage parameters. The 1A difference does not affect substitution validity for applications designed around the 27A minimum specification.

Q: What compliance differences exist between these parts?

A: The MP6KE16AE3 is RoHS non-compliant and qualified to MIL-PRF-19500 military standards. The P6KE16A is ROHS3 compliant, suitable for commercial and industrial markets with environmental compliance requirements. Applications subject to RoHS directives must use the P6KE16A or equivalent compliant alternatives.

Q: How do inventory levels affect part selection?

A: The MP6KE16AE3 has 806 pcs in stock, while the P6KE16A has 10,100 pcs available. For high-volume production or long-term supply chain planning, the P6KE16A offers greater availability. For low-volume or specialized military applications, the MP6KE16AE3 remains the specified choice despite lower inventory.
