MP4KE130AE3 Equivalent & Substitute Parts

Part Overview

The MP4KE130AE3 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This through-hole component operates with a reverse standoff voltage of 111V and provides clamping at 179V maximum, with a peak pulse current rating of 2.2A. The device is classified as military-grade and qualified to MIL-PRF-19500 standards.

Substitute parts are identified when equivalent electrical performance parameters and mechanical compatibility are maintained across the same package type and functional category. Alternative sources become necessary due to inventory availability, supply chain considerations, or specific compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP4KE130AE3 is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 111V
• Voltage - Breakdown (Min): 124V
• Voltage - Clamping (Max) @ Ipp: 179V
• Package / Case: DO-204AL (DO-41) axial through-hole
• Type: Zener, Unidirectional
• Unidirectional Channels: 1

Allowable Variation Parameters:

• Current - Peak Pulse (10/1000µs): Minimum 2.2A (higher values acceptable)
• Power - Peak Pulse: Minimum 400W (higher values acceptable)
• Operating Temperature Range: May extend beyond specified range
• Packaging Format: Bulk or Tape & Reel formats are interchangeable for through-hole applications
• Compliance Status: RoHS and qualification certifications may differ

The P4KE130A from Taiwan Semiconductor Corporation qualifies as a substitute based on matching all critical parameters while maintaining functional equivalence in the TVS diode category.

Engineering Selection Recommendations

MP4KE130AE3 (Microchip Technology):

• Primary selection for applications requiring military-grade qualification (MIL-PRF-19500)
• Specified for systems with strict military or aerospace compliance mandates
• RoHS non-compliant status requires verification against end-application requirements
• Operating temperature range of -65°C to 150°C suitable for standard industrial environments

P4KE130A (Taiwan Semiconductor Corporation):

• Suitable for applications where RoHS3 compliance is required
• Extended operating temperature range (-55°C to 175°C) accommodates higher-temperature environments
• Higher peak pulse current rating (2.3A vs. 2.2A) provides additional margin in transient protection circuits
• Tape & Reel packaging format supports automated assembly processes
• Equivalent electrical performance across all critical voltage and power parameters

Selection between these parts depends on specific compliance requirements, temperature operating conditions, and assembly methodology rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can the P4KE130A directly replace the MP4KE130AE3 in existing designs?

A: Yes, the P4KE130A provides direct functional replacement in circuit applications. Both devices share identical voltage ratings (111V standoff, 179V clamping), power dissipation (400W peak pulse), and DO-204AL package specifications. The higher peak pulse current rating (2.3A) of the P4KE130A is compatible with designs specified for 2.2A minimum.

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

A: The MP4KE130AE3 operates from -65°C to 150°C, while the P4KE130A operates from -55°C to 175°C. The P4KE130A provides extended high-temperature capability. Selection depends on the actual operating environment; if maximum junction temperature remains below 150°C, both devices are functionally equivalent.

Q: Are there packaging format differences between these parts?

A: The MP4KE130AE3 is supplied in Bulk packaging, while the P4KE130A is supplied in Tape & Reel format. Both are through-hole axial components in DO-204AL (DO-41) package. Tape & Reel format is standard for automated assembly; Bulk format is typical for manual assembly or kit applications. The physical component dimensions and pinout are identical.

Q: What compliance differences exist between these substitutes?

A: The MP4KE130AE3 is MIL-PRF-19500 qualified and RoHS non-compliant. The P4KE130A is RoHS3 compliant. Applications subject to RoHS directives or commercial electronics standards require the P4KE130A. Military or aerospace applications with MIL-PRF-19500 requirements specify the MP4KE130AE3.

Q: Are the electrical characteristics identical for circuit design purposes?

A: The critical electrical parameters are identical: reverse standoff voltage (111V), breakdown voltage (124V minimum), and clamping voltage (179V maximum). The P4KE130A has a slightly higher peak pulse current specification (2.3A vs. 2.2A), which represents additional design margin and does not affect compatibility.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes, both devices use the same DO-204AL (DO-41) axial through-hole package and are mechanically compatible with standard component insertion equipment. The P4KE130A in Tape & Reel format is optimized for automated pick-and-place systems, while the MP4KE130AE3 in Bulk format is suitable for manual or semi-automated assembly.
