5KP7.5AE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP7.5AE3/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This component features a 7.5V reverse standoff voltage with a 12.9V maximum clamping voltage and peak pulse current handling of 388A at 5000W peak pulse power. The device is housed in a P600 axial through-hole package and is currently in active production status with full RoHS3 compliance.

Equivalent and substitute parts are identified based on matching electrical performance parameters, mechanical compatibility, and thermal operating ranges. Substitutes are selected where voltage ratings, clamping characteristics, and package form factors align with the original specification.

Substitute Part Grouping Explanation

Substitute parts for the 5KP7.5AE3/TR13 are classified into two categories based on electrical and mechanical compatibility:

Category 1: Full Electrical and Mechanical Equivalents Parts that maintain identical voltage ratings (7.5V reverse standoff, 12.9V clamping), peak pulse current specifications, and P600 axial package form factor. These substitutes are directly interchangeable in circuit designs without modification.

Category 2: Functional Equivalents with Package Variation Parts that maintain identical voltage ratings and clamping characteristics but utilize alternative through-hole package configurations (DO-201). These substitutes are functionally equivalent but require mechanical board layout adjustment due to different lead spacing and package dimensions.

Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 7.5V
• Voltage - Clamping (Max) @ Ipp: 12.9V
• Voltage - Breakdown (Min): 8.33V
• Operating Temperature Range: -55°C to 175°C
• Type: Zener, Unidirectional
• Mounting Type: Through Hole
• RoHS3 Compliance: Required
• Product Status: Active

Engineering Selection Recommendations

5KP7.5A (Littelfuse Inc.) - Primary Substitute

The 5KP7.5A is the preferred direct substitute for the 5KP7.5AE3/TR13. Both devices share identical voltage specifications (7.5V reverse standoff, 12.9V clamping), equivalent peak pulse current ratings (395.3A versus 388A), and matching 5000W peak pulse power dissipation. The P600 axial package form factor is identical, enabling direct board-level substitution without layout modification. Both components maintain active product status, full RoHS3 compliance, and unlimited moisture sensitivity rating. The 5KP7.5A is available in Cut Tape packaging with 5200 units in stock, providing supply continuity.

LCE7.5A (Littelfuse) - Functional Substitute with Limitations

The LCE7.5A maintains identical voltage ratings (7.5V reverse standoff, 12.9V clamping) and operating temperature range, ensuring electrical compatibility for overvoltage protection function. However, this substitute exhibits reduced peak pulse current handling (100A versus 388A) and lower peak pulse power dissipation (1500W versus 5000W). The DO-201 package differs mechanically from the P600 package, requiring board layout modification for lead spacing and mounting hole adjustment. This substitute is suitable only for applications where peak pulse current requirements do not exceed 100A and peak pulse power does not exceed 1500W. Full RoHS3 compliance and active product status are maintained.

Compliance and Certification Alignment

All identified substitutes maintain RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility with the original component specification.

Frequently Asked Questions (FAQ)

Q: Can the 5KP7.5A be used as a direct replacement for the 5KP7.5AE3/TR13 without circuit modification?

A: Yes. The 5KP7.5A is electrically and mechanically equivalent. Both devices feature identical 7.5V reverse standoff voltage, 12.9V clamping voltage, and P600 axial through-hole package configuration. Peak pulse current ratings are equivalent (395.3A versus 388A), and peak pulse power dissipation matches at 5000W. No circuit or board layout modification is required.

Q: What are the key differences between the 5KP7.5A and LCE7.5A substitutes?

A: The primary differences are peak pulse current handling and package form factor. The 5KP7.5A maintains 388A peak pulse current and 5000W power dissipation in a P600 package. The LCE7.5A reduces peak pulse current to 100A and power dissipation to 1500W, and uses a DO-201 package requiring board layout modification. Voltage ratings remain identical across both substitutes.

Q: Is the LCE7.5A suitable for all applications using the 5KP7.5AE3/TR13?

A: The LCE7.5A is suitable only for applications where peak pulse current does not exceed 100A and peak pulse power dissipation does not exceed 1500W. Applications requiring the full 388A peak pulse current or 5000W power dissipation capability must use the 5KP7.5A or original 5KP7.5AE3/TR13 component.

Q: Do all substitute parts maintain the same operating temperature range?

A: Yes. The 5KP7.5A and LCE7.5A both operate across the identical temperature range of -55°C to 175°C (TJ), matching the original 5KP7.5AE3/TR13 specification.

Q: Are there packaging differences that affect board assembly?

A: The 5KP7.5A uses the P600 axial package, identical to the original component, requiring no assembly modification. The LCE7.5A uses the DO-201 package, which has different lead spacing and dimensions, requiring board layout adjustment for mounting hole positioning and lead clearance.

Q: Do all substitute parts meet RoHS3 compliance requirements?

A: Yes. Both the 5KP7.5A and LCE7.5A are RoHS3 compliant and REACH unaffected, matching the regulatory status of the original 5KP7.5AE3/TR13 component.

Q: What is the moisture sensitivity level for substitute parts?

A: Both substitute parts maintain MSL 1 (Unlimited) rating, identical to the original component, indicating no moisture sensitivity restrictions for storage or handling.
