5KP40AE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP40AE3/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This component features a 40V reverse standoff voltage with a 64.5V maximum clamping voltage and 77.5A peak pulse current capability at 5000W peak pulse power. The device is housed in a P600 axial through-hole package and is RoHS3 compliant with unlimited moisture sensitivity rating.

Substitute Part Grouping Explanation

Substitution of the 5KP40AE3/TR13 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - Reverse Standoff (Typ): 40V
Voltage - Clamping (Max) @ Ipp: 64.5V (±tolerance)
Current - Peak Pulse (10/1000µs): 77.5A (±tolerance)
Power - Peak Pulse: 5000W
Type: Zener, Unidirectional
Mounting Type: Through Hole
Package / Case: P600 or equivalent axial package

Secondary Substitution Criteria:

Substitute parts are grouped into two categories:

Direct Electrical Equivalents: Parts with identical or near-identical voltage and current ratings, maintaining the same 5000W power dissipation and P600 package format.

Higher Power Alternatives: Parts with the same voltage ratings but increased current and power handling capabilities, suitable for applications requiring enhanced transient protection margins.

Engineering Selection Recommendations

Direct Electrical Equivalents (Recommended for 1:1 Replacement):

The 5KP40A manufactured by Diotec Semiconductor provides direct electrical equivalence with identical voltage ratings (40V standoff, 64.5V clamping) and current specifications (78A peak pulse). This part maintains RoHS3 compliance and P600 axial package compatibility. The operating temperature range extends to -50°C minimum, which is acceptable for most applications requiring -55°C operation.

The 5KP40A-E3/54 from Vishay General Semiconductor (TransZorb® series) offers identical electrical specifications and package format. However, this part is RoHS non-compliant, which may restrict its use in applications subject to RoHS regulations.

Alternative Package Format:

The 5KP40A-TP from Micro Commercial Co maintains electrical equivalence but uses an R-6 axial package instead of P600. This part is suitable for applications where R-6 package compatibility exists and provides RoHS3 compliance.

Higher Power Alternative:

The 15KPA40A from MDE Semiconductor Inc maintains the 40V reverse standoff voltage with enhanced current handling (229.5A peak pulse) and 15000W peak pulse power. This part is suitable for applications requiring increased transient protection margins and is RoHS3 compliant.

Voltage Variant:

The 5KP48A from Littelfuse Inc. features a higher 48V reverse standoff voltage with corresponding 77.4V clamping voltage. This part is suitable only for applications where the higher voltage rating is compatible with circuit requirements.

Compliance Considerations:

All recommended direct equivalents maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the 5KP40A-E3/54 be used as a direct replacement for the 5KP40AE3/TR13?

A: The 5KP40A-E3/54 provides identical electrical specifications (40V standoff, 64.5V clamping, 77.5A peak pulse, 5000W power) and P600 axial package compatibility. However, this part is RoHS non-compliant, whereas the original part is RoHS3 compliant. Selection depends on regulatory requirements for the application.

Q: What is the difference between the 5KP40A and 5KP40AE3/TR13?

A: Both parts share identical electrical specifications (40V standoff, 64.5V clamping, 77.5A peak pulse, 5000W power) and P600 axial package format. The primary difference is the manufacturer (Diotec vs. Microchip Technology). The 5KP40A has a minimum operating temperature of -50°C compared to -55°C for the original part.

Q: When should the 15KPA40A be selected instead of direct equivalents?

A: The 15KPA40A maintains the same 40V reverse standoff voltage but provides significantly higher current handling (229.5A vs. 77.5A) and power dissipation (15000W vs. 5000W). This part is selected for applications requiring enhanced transient protection capability or where higher surge currents are anticipated.

Q: Is the 5KP48A compatible with circuits designed for the 5KP40AE3/TR13?

A: The 5KP48A is not a direct replacement. It features a higher 48V reverse standoff voltage and 77.4V clamping voltage compared to the 40V and 64.5V specifications of the original part. This part is suitable only for applications where the higher voltage rating is compatible with circuit design parameters.

Q: What packaging options are available for 40V TVS diodes equivalent to the 5KP40AE3/TR13?

A: The primary package format is P600 axial, available from multiple manufacturers including Diotec Semiconductor (5KP40A) and Littelfuse Inc. (5KP48A). An alternative R-6 axial package is available from Micro Commercial Co (5KP40A-TP). All packages are through-hole mounted and compatible with standard PCB assembly processes.

Q: Are all substitute parts RoHS3 compliant?

A: Most substitute parts are RoHS3 compliant, including the 5KP40A (Diotec), 5KP40A-TP (Micro Commercial Co), 5KP48A (Littelfuse), and 15KPA40A (MDE Semiconductor). The 5KP40A-E3/54 from Vishay is RoHS non-compliant. Compliance verification is required for applications subject to RoHS regulations.

Q: What is the significance of the P600 package designation?

A: P600 is an axial through-hole package format for TVS diodes. It specifies the physical dimensions and lead configuration, ensuring mechanical compatibility with PCB footprints designed for this package type. The R-6 package from Micro Commercial Co is an alternative axial format with different physical dimensions.
