MP6KE62AE3 Equivalent & Substitute Parts

Part Overview

The MP6KE62AE3 is an active-status Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology. This unidirectional zener-type device provides transient overvoltage protection in general-purpose applications through a through-hole T-18 axial package. The device operates across a junction temperature range of -65°C to 150°C and meets MIL-PRF-19500 military qualification standards. Substitute parts are identified to provide equivalent electrical performance and functional compatibility for applications requiring TVS protection at the specified voltage and power ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP6KE62AE3 are identified based on electrical parameter equivalence within the following criteria:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 53V
• Voltage - Clamping (Max) @ Ipp: 85V
• Power - Peak Pulse: 600W
• Type: Unidirectional Zener
• Mounting Type: Through Hole

The P6KE62A from Diotec Semiconductor meets these electrical specifications with identical standoff voltage, clamping voltage, and peak pulse power rating. The peak pulse current specification (7.4A) exceeds the minimum requirement (7.1A), providing equivalent or superior transient suppression capability. Both devices function as general-purpose TVS diodes with single unidirectional channels in through-hole axial packages.

Parameter Comparison

Engineering Selection Recommendations

MP6KE62AE3 (Microchip Technology):

• Active product status with 1040 units in stock
• MIL-PRF-19500 military qualification
• Military-grade classification
• Operating temperature range: -65°C to 150°C
• RoHS non-compliant; REACH Unaffected
• Recommended for applications requiring military-grade certification and extended low-temperature operation

P6KE62A (Diotec Semiconductor):

• Active product status with 6300 units in stock
• Higher peak pulse current rating (7.4A vs. 7.1A)
• Extended high-temperature operation: -50°C to 175°C
• RoHS status not applicable; REACH status vendor undefined
• DO-15 package differs from T-18 package; physical footprint and lead configuration require circuit board layout verification
• Recommended for applications with higher ambient temperature requirements and where military qualification is not mandated

Package Consideration: The MP6KE62AE3 uses a T-18 axial package while the P6KE62A uses a DO-15 (DO-204AC) axial package. Both are through-hole axial configurations, but physical dimensions and lead spacing differ. Circuit board layout compatibility must be confirmed before substitution.

Frequently Asked Questions (FAQ)

Q: Can the P6KE62A directly replace the MP6KE62AE3 in all applications?

A: Electrical substitution is valid based on matching voltage ratings (53V standoff, 85V clamping) and power specifications (600W peak pulse). However, the different package types (T-18 vs. DO-15) require verification of physical fit and circuit board layout compatibility. Applications requiring MIL-PRF-19500 certification must retain the MP6KE62AE3.

Q: What is the significance of the higher peak pulse current in the P6KE62A (7.4A vs. 7.1A)?

A: The P6KE62A's 7.4A peak pulse current exceeds the MP6KE62AE3's 7.1A specification. Both devices maintain the same 600W peak pulse power rating and 85V clamping voltage. The higher current capability in the substitute part provides equivalent or superior transient suppression performance at the specified voltage levels.

Q: Are there temperature range differences between these parts?

A: Yes. The MP6KE62AE3 operates from -65°C to 150°C (TJ), while the P6KE62A operates from -50°C to 175°C (TJ). The MP6KE62AE3 provides extended low-temperature performance; the P6KE62A provides extended high-temperature performance. Application temperature requirements determine which device is appropriate.

Q: Does the P6KE62A meet military specifications?

A: The P6KE62A does not carry MIL-PRF-19500 qualification. The MP6KE62AE3 is military-grade qualified. Applications requiring military-grade components must use the MP6KE62AE3.

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

A: Both are through-hole axial packages with radial leads. The T-18 package (Microchip) and DO-15 package (Diotec) have different physical dimensions and lead spacing. Circuit board layout, PCB hole spacing, and component placement must be verified for compatibility before substitution.

Q: Are there RoHS or compliance differences?

A: The MP6KE62AE3 is RoHS non-compliant. The P6KE62A RoHS status is not applicable. Applications subject to RoHS directives require clarification of exemption status or alternative compliant components.
