MPTE-005G Equivalent & Substitute Parts

Part Overview

The MPTE-005G is a Transient Voltage Suppressor (TVS) diode manufactured by onsemi, designed for general-purpose transient voltage protection in through-hole axial configurations. This component features a 5V reverse standoff voltage with a 9.4V maximum clamping voltage and 160A peak pulse current capability. The MPTE-005G is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPTE-005G is determined by the following critical electrical and mechanical parameters:

• Voltage Rating: Reverse standoff voltage of 5V and breakdown voltage minimum of 6V
• Clamping Voltage: Maximum clamping voltage at Ipp must not exceed 9.4V to maintain circuit protection integrity
• Peak Pulse Current: Minimum 160A capability at 8/20µs pulse duration
• Package Type: Through-hole axial configuration (DO-201AD or equivalent P600 package)
• Unidirectional Protection: Single-channel Zener diode topology
• Temperature Range: Operating range of -55°C to 175°C minimum

The substitute parts 5KP5.0A and 5KP5.0AE3/TR13 meet these criteria with equivalent voltage ratings, superior peak pulse current ratings (554.3A and 543A respectively), and compatible through-hole axial packaging. Both substitutes maintain the same 5V reverse standoff voltage and 9.2V clamping voltage specification, ensuring functional compatibility within the allowed parameter tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both 5KP5.0A and 5KP5.0AE3/TR13 are active production alternatives to the obsolete MPTE-005G. Selection between these substitutes should be based on procurement and packaging requirements:

5KP5.0A (Littelfuse Inc.) is supplied in Cut Tape (CT) packaging and carries ROHS3 compliance with MSL 1 rating, indicating superior moisture tolerance for storage and handling.

5KP5.0AE3/TR13 (Microchip Technology) is supplied in Tape & Reel (TR) format, also ROHS3 compliant with MSL 1 rating, and is optimized for automated assembly processes.

Both parts exceed the electrical performance requirements of the MPTE-005G with higher peak pulse current ratings (543A–554.3A versus 160A) and superior power dissipation capability (5kW versus 1.5kW), providing enhanced protection margins. The clamping voltage specifications (9.2V) are within acceptable tolerance of the original part (9.4V). Operating temperature ranges of -55°C to 175°C meet or exceed the original specification for most applications, with the exception of the lower temperature limit (-55°C versus -65°C).

Frequently Asked Questions (FAQ)

Q: Can 5KP5.0A and 5KP5.0AE3/TR13 be used interchangeably with MPTE-005G?

A: Yes, both parts are functionally equivalent for general-purpose transient voltage suppression applications. They share identical 5V reverse standoff voltage and 9.2V clamping voltage specifications. The primary differences are packaging format (Cut Tape versus Tape & Reel) and manufacturer source.

Q: What is the significance of the higher peak pulse current rating in the substitute parts?

A: The substitute parts (5KP5.0A and 5KP5.0AE3/TR13) are rated for 543A–554.3A peak pulse current compared to the MPTE-005G's 160A rating. This higher rating provides additional transient suppression capability and thermal margin, making them suitable for applications with higher energy transients.

Q: Are there compatibility concerns with the P600 package versus DO-201AD?

A: Both P600 and DO-201AD are through-hole axial package formats with compatible mechanical and electrical characteristics. Physical dimensions may vary slightly; verify PCB footprint compatibility before implementation.

Q: What is the impact of the lower minimum operating temperature on the substitute parts?

A: The substitute parts operate from -55°C minimum versus -65°C for the MPTE-005G. For applications requiring operation below -55°C, the original MPTE-005G specification must be maintained or alternative parts with extended low-temperature ratings must be identified.

Q: Do the substitute parts meet RoHS compliance requirements?

A: Yes, both 5KP5.0A and 5KP5.0AE3/TR13 are ROHS3 compliant, meeting current environmental and material restriction standards.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging is suitable for manual or semi-automated assembly processes. Tape & Reel (TR) packaging is optimized for high-speed automated pick-and-place assembly equipment. Selection depends on manufacturing process requirements.
