5KP5.0A-TP Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 5KP5.0A-TP is an active Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This unidirectional Zener-type device provides 5V reverse standoff voltage with a 9.2V maximum clamping voltage and 5000W peak pulse power rating. The component is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the TVS diode category, enabling component sourcing flexibility while maintaining circuit protection specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP5.0A-TP is determined by electrical parameter matching within defined tolerances and mechanical compatibility. The critical parameters governing substitution are:

• Voltage - Reverse Standoff: 5V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 9.2V (exact match required)
• Power - Peak Pulse: 5000W (exact match required)
• Mounting Type: Through Hole (required for form factor compatibility)
• Unidirectional Channels: 1 (required for circuit topology compatibility)

Substitute parts are classified into two categories:

Direct Equivalents: Parts with identical electrical specifications, matching package designations, and equivalent or superior compliance ratings. These parts provide full functional interchangeability.

Similar Alternatives: Parts with matching core voltage and power specifications but differing in secondary parameters such as peak pulse current, package case designation, or compliance status. These parts provide functional protection capability with noted parameter variations.

Parameter Comparison

Engineering Selection Recommendations

5KP5.0A (Littelfuse Inc., Direct Equivalent): This part provides full electrical and thermal equivalence to the 5KP5.0A-TP with identical voltage specifications, power rating, and operating temperature range. Both parts maintain ROHS3 compliance. The primary distinction is packaging format (P600 vs. R-6 case designation) and supplier availability. This part is suitable for direct substitution in applications requiring 5000W peak pulse protection at 9.2V clamping voltage.

5KP5.0A-B (Littelfuse Inc., Similar Alternative): This part matches the electrical specifications and power rating of the main part with identical voltage parameters and ROHS3 compliance. The packaging differs in supply format (Bulk vs. Cut Tape). This part is suitable for substitution where bulk packaging is acceptable and equivalent electrical performance is required.

1N5907 (Microchip Technology, Similar Alternative): This part provides reduced peak pulse power capability (1500W vs. 5000W) and lower peak pulse current (120A vs. 554.3A). The clamping voltage is 8.5V compared to 9.2V, representing a 0.7V reduction in maximum clamp level. RoHS compliance status is non-compliant, differing from the main part. This part is suitable only for applications with reduced transient energy requirements and where RoHS non-compliance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can 5KP5.0A replace 5KP5.0A-TP in all applications?

A: Yes. The 5KP5.0A provides identical electrical specifications including 5V reverse standoff voltage, 9.2V clamping voltage, and 5000W peak pulse power. Both parts maintain ROHS3 compliance and equivalent operating temperature ranges. Package case designation differs (P600 vs. R-6), but both are axial through-hole configurations suitable for standard PCB mounting.

Q: What are the limitations of using 1N5907 as a substitute?

A: The 1N5907 provides reduced transient protection capability with 1500W peak pulse power versus 5000W for the main part. Peak pulse current is limited to 120A compared to 554.3A. The maximum clamping voltage is 8.5V, which is 0.7V lower than the 9.2V specification of the main part. Additionally, the 1N5907 is RoHS non-compliant. This part is suitable only for lower-energy transient applications where these reduced specifications are acceptable.

Q: Are there package compatibility considerations between substitute parts?

A: Yes. The 5KP5.0A-TP uses R-6 axial package, while 5KP5.0A and 5KP5.0A-B use P600 axial package. Both are through-hole axial configurations with similar form factors suitable for standard PCB layouts. The 1N5907 uses DO-13 package, also axial through-hole but with different physical dimensions. PCB footprint verification is required when substituting between different package designations.

Q: Which substitute part is recommended for new designs?

A: The 5KP5.0A (Littelfuse Inc.) is the recommended substitute for new designs, providing full electrical equivalence, ROHS3 compliance, and active product status with established supply chain availability.

Q: Does packaging format (Cut Tape vs. Bulk) affect electrical performance?

A: No. Packaging format affects only supply and handling logistics. Cut Tape and Bulk packaging contain identical components with identical electrical specifications. Selection between packaging formats depends on procurement volume and assembly process requirements.
