M5KP30AE3 Equivalent & Substitute Parts

Part Overview

The M5KP30AE3 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This component features a 30V reverse standoff voltage with a 48.4V maximum clamping voltage and 103A 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 M5KP30AE3 maintains active product status with 1075 units currently in stock. 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.

Substitute Part Grouping Explanation

Substitute parts for the M5KP30AE3 are identified based on electrical parameter equivalence within the transient voltage suppressor category. The primary substitution criteria are:

Electrical Equivalence Parameters:

• Voltage - Reverse Standoff (Typ): 30V
• Voltage - Breakdown (Min): 33.3V
• Voltage - Clamping (Max) @ Ipp: 48.4V
• Current - Peak Pulse (10/1000µs): 103A
• Power - Peak Pulse: 5000W
• Type: Zener, Unidirectional

Mechanical Compatibility Parameters:

• Mounting Type: Through Hole
• Package Category: Axial

Parts meeting these electrical and mechanical criteria are classified as direct substitutes. The 5KP30A from Diotec Semiconductor satisfies all core electrical parameters and maintains through-hole axial mounting compatibility, establishing it as a functional equivalent despite differences in packaging format and compliance certifications.

Engineering Selection Recommendations

M5KP30AE3 Selection Criteria:

• Military-grade qualification (MIL-PRF-19500) required
• RoHS non-compliant applications acceptable
• Bulk packaging format suitable for application
• Operating temperature range -65°C to 150°C sufficient
• DO-204AR package specification required

5KP30A Selection Criteria:

• ROHS3 compliance required for end application
• Tape & Reel packaging format required for automated assembly
• Extended upper operating temperature to 175°C beneficial
• P600 axial package acceptable as mechanical equivalent
• Military qualification not required
• Higher inventory availability (4345 units vs. 1075 units)

Both parts deliver identical electrical performance for transient voltage suppression at 30V standoff with 103A peak pulse current and 5000W peak power dissipation. Selection between these parts depends on compliance requirements, packaging format needs, and operating temperature specifications rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the 5KP30A directly replace the M5KP30AE3 in all applications?

A: The 5KP30A provides electrical equivalence across all core TVS parameters. However, replacement suitability depends on application-specific requirements. If military qualification (MIL-PRF-19500) is mandatory, the M5KP30AE3 is required. If RoHS3 compliance is required, the 5KP30A is necessary. Both parts function identically for transient voltage suppression in the 30V class.

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

A: Both DO-204AR and P600 are axial through-hole package designations for diodes. They represent different manufacturer package naming conventions but serve the same mechanical function. Physical dimensions may vary slightly; component placement and board layout compatibility should be verified for specific PCB designs.

Q: Does the 5KP30A's extended temperature range (-50°C to 175°C) affect substitution?

A: The 5KP30A's extended upper temperature limit to 175°C (versus 150°C for M5KP30AE3) provides additional thermal margin. This does not prevent substitution; it represents an enhancement for applications requiring higher temperature operation. Applications limited to -65°C to 150°C operate within both parts' specifications.

Q: Why is the 5KP30A supplied in Tape & Reel format while M5KP30AE3 is Bulk?

A: Packaging format reflects supplier inventory and distribution strategy. Tape & Reel format supports automated assembly processes, while Bulk format suits manual assembly or lower-volume applications. Format selection depends on manufacturing process requirements, not electrical performance.

Q: Are there electrical performance differences between these parts?

A: No. Both parts exhibit identical electrical specifications: 30V reverse standoff, 33.3V minimum breakdown, 48.4V maximum clamping, 103A peak pulse current, and 5000W peak power dissipation. Differences are limited to compliance certifications, packaging format, and operating temperature range.

Q: What compliance considerations apply to substitution?

A: The M5KP30AE3 holds MIL-PRF-19500 military qualification and is RoHS non-compliant. The 5KP30A is ROHS3 compliant with REACH information available upon request. Applications requiring military specifications must use M5KP30AE3. Applications requiring RoHS3 compliance must use 5KP30A. Compliance requirements drive part selection.
