M5KP36AE3 Equivalent & Substitute Parts

Part Overview

The M5KP36AE3 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This component features a 36V reverse standoff voltage with a 58.1V maximum clamping voltage and 86A peak pulse current capability. The device is housed in a DO-204AR axial through-hole package and is qualified to MIL-PRF-19500 military standards. The M5KP36AE3 maintains active product status and is available in bulk packaging. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific packaging or compliance requirements necessitate component substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M5KP36AE3 is determined by electrical and mechanical parameter equivalence. The critical parameters that define substitutability are:

Electrical Parameters:

• Voltage - Reverse Standoff (Typ): 36V
• Voltage - Breakdown (Min): 40V
• Voltage - Clamping (Max) @ Ipp: 58.1V
• Current - Peak Pulse (10/1000µs): 86A
• Power - Peak Pulse: 5000W

Mechanical Parameters:

• Type: Zener (unidirectional)
• Unidirectional Channels: 1
• Mounting Type: Through Hole
• Package Style: Axial

The 5KP36A manufactured by Diotec Semiconductor satisfies all electrical parameter requirements and maintains identical through-hole axial package compatibility. This part is therefore classified as a direct electrical and mechanical equivalent, with differences limited to packaging format (Tape & Reel versus Bulk) and compliance certifications.

Engineering Selection Recommendations

M5KP36AE3 (Microchip Technology):

• Primary selection for applications requiring MIL-PRF-19500 military qualification
• Specified for military-grade applications and systems requiring formal qualification documentation
• RoHS non-compliant; suitable for legacy systems and military procurement
• Operating temperature range: -65°C to 150°C
• Bulk packaging format

5KP36A (Diotec Semiconductor):

• Direct electrical equivalent with identical voltage and current specifications
• ROHS3 compliant; suitable for commercial and industrial applications with RoHS requirements
• Extended upper operating temperature limit (175°C) provides thermal margin in high-temperature environments
• Tape & Reel packaging format supports automated assembly processes
• Lower temperature limit (-50°C) is suitable for most industrial applications

Selection between these parts is determined by compliance requirements and packaging format. The M5KP36AE3 is specified when military qualification is mandatory. The 5KP36A is selected when RoHS compliance is required or when automated assembly with Tape & Reel packaging is necessary.

Frequently Asked Questions (FAQ)

Q: Are the M5KP36AE3 and 5KP36A electrically interchangeable?

A: Yes. Both devices are unidirectional TVS diodes with identical electrical specifications: 36V reverse standoff voltage, 58.1V maximum clamping voltage, 86A peak pulse current, and 5000W peak pulse power rating. They perform identically in circuit applications.

Q: What is the difference between DO-204AR and P600 packages?

A: Both are axial through-hole packages for TVS diodes. DO-204AR is the Microchip designation; P600 is the Diotec designation. Both packages are mechanically compatible with standard through-hole PCB layouts and have equivalent lead spacing and form factors.

Q: Can the 5KP36A replace the M5KP36AE3 in military applications?

A: The 5KP36A is not qualified to MIL-PRF-19500. It cannot be used as a direct replacement in systems requiring military qualification. The M5KP36AE3 must be specified for military procurement.

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

A: The M5KP36AE3 operates from -65°C to 150°C; the 5KP36A operates from -50°C to 175°C. The 5KP36A provides extended high-temperature capability. For applications operating below -50°C, the M5KP36AE3 is required.

Q: Does RoHS compliance affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental impact, not electrical performance. Both parts deliver identical electrical characteristics. RoHS compliance is a procurement and regulatory requirement, not a functional specification.

Q: Which part should be selected for new designs?

A: For new commercial and industrial designs without military requirements, the 5KP36A is preferred due to ROHS3 compliance and extended temperature range. For military systems or legacy applications, the M5KP36AE3 is specified.

Q: Are there inventory considerations between these parts?

A: The M5KP36AE3 has 679 pieces in stock (bulk packaging). The 5KP36A has 4120 pieces in stock (Tape & Reel packaging). Availability may influence selection for time-sensitive procurement.
