Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP40E3/TR13 are selected based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Voltage - Reverse Standoff (Typ): 40V
• Type: Zener, Unidirectional
• Mounting Type: Through Hole
• Package / Case: P600 or R-6 Axial
• Operating Temperature Range: -55°C to 175°C minimum
• RoHS3 Compliance: Required

Secondary Compatibility Parameters:

• Voltage - Breakdown (Min): 44.4V to 44.7V range
• Voltage - Clamping (Max) @ Ipp: 64.5V to 71.4V range
• Current - Peak Pulse (10/1000µs): 70A minimum
• Power - Peak Pulse: 5000W minimum

Substitutes are grouped into two categories: direct equivalents with identical electrical performance and compatible alternatives with equivalent or superior electrical ratings within the specified voltage and power parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Electrical Performance):

The 5KP40A manufactured by Diotec Semiconductor serves as a direct electrical equivalent to the 5KP40E3/TR13. Both devices share identical reverse standoff voltage (40V), breakdown voltage (44.4V), and peak pulse power rating (5000W). The 5KP40A maintains RoHS3 compliance and operates across the same temperature range with the exception of the lower temperature limit (-50°C versus -55°C). This part is available in high inventory quantities (3400 pcs) and is suitable for direct substitution in applications where the slightly reduced low-temperature specification is acceptable.

Compatible Alternatives (Enhanced Electrical Performance):

The 15KPA40A manufactured by MDE Semiconductor Inc provides enhanced electrical performance with superior peak pulse current (229.5A versus 70A) and peak pulse power (15000W versus 5000W) while maintaining the same 40V reverse standoff voltage. This part is suitable for applications requiring higher transient energy absorption capacity. The 15KPA40A maintains RoHS3 compliance and identical operating temperature range (-55°C to 175°C). Inventory availability is substantial (1721 pcs).

Package Variant:

The 5KP40A-TP manufactured by Micro Commercial Co provides electrical equivalence with identical voltage ratings and power specifications. This variant is supplied in Cut Tape packaging with R-6 axial package configuration instead of the standard P600. The R-6 package maintains mechanical compatibility with Through Hole mounting applications. RoHS3 compliance and operating temperature range (-55°C to 175°C) are maintained. This option is appropriate when Cut Tape packaging format is preferred for automated assembly processes.

Limited Data Availability:

The P6KE51A manufactured by Fairchild Semiconductor is listed as a substitute part; however, complete electrical parameter data is not provided in the available documentation. This part cannot be fully evaluated for substitution without access to complete voltage and current specifications.

All substitute parts maintain Active product status and RoHS3 compliance, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA40A be used as a direct replacement for the 5KP40E3/TR13?

A: The 15KPA40A is electrically compatible for substitution. Both devices share the same 40V reverse standoff voltage and operate across identical temperature ranges. The 15KPA40A provides enhanced peak pulse current (229.5A) and power (15000W) ratings, making it suitable for applications requiring higher transient energy absorption. The primary difference is the increased electrical performance capability, which does not create incompatibility in applications designed for the 5KP40E3/TR13.

Q: What is the difference between the 5KP40A and 5KP40A-TP?

A: The 5KP40A and 5KP40A-TP are electrically equivalent, both providing 40V reverse standoff voltage and 5000W peak pulse power. The primary difference is packaging format: the 5KP40A is supplied in standard format, while the 5KP40A-TP is supplied in Cut Tape (CT) configuration with R-6 axial package. Both maintain Through Hole mounting compatibility. The R-6 package variant is selected when automated tape-fed assembly processes are required.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts (15KPA40A, 5KP40A, and 5KP40A-TP) are RoHS3 compliant, matching the compliance status of the 5KP40E3/TR13. This ensures regulatory continuity and environmental compliance across all substitution options.

Q: What is the operating temperature difference between the 5KP40A and the main part?

A: The 5KP40A operates from -50°C to 175°C, while the 5KP40E3/TR13 operates from -55°C to 175°C. The 5KP40A has a 5°C higher minimum operating temperature. This difference is significant only in applications requiring operation below -50°C. For standard industrial and commercial applications operating above -50°C, this difference is not a limiting factor.

Q: Can the P6KE51A be used as a substitute?

A: The P6KE51A is listed as a substitute part; however, complete electrical parameter specifications are not available in the provided documentation. Substitution cannot be confirmed without access to the device's voltage ratings, current specifications, and package configuration details.

Q: What packaging options are available for substitutes?

A: Substitute parts are available in three packaging formats: Tape & Reel (TR) for the main part, Bulk for the 15KPA40A, and Cut Tape (CT) for the 5KP40A-TP. All maintain Through Hole axial mounting compatibility with either P600 or R-6 package configurations. Selection depends on assembly process requirements and inventory management preferences.

Q: Are there inventory considerations when selecting a substitute?

A: Inventory availability varies across substitute options. The 5KP40A has the highest inventory (3400 pcs), followed by the 15KPA40A (1721 pcs) and 5KP40A-TP (1517 pcs). The main part 5KP40E3/TR13 has 1143 pcs available. Inventory levels should be considered in conjunction with electrical performance requirements and packaging preferences for supply chain planning.
