5KP7.5CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP7.5CE3/TR13 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This through-hole component features a 7.5V reverse standoff voltage and 14.3V maximum clamping voltage, with a peak pulse power rating of 5000W. The part is currently active in production and RoHS3 compliant. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when procurement requirements necessitate alternative manufacturers or packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP7.5CE3/TR13 is determined by the following critical parameters:

Voltage Specifications: The reverse standoff voltage (7.5V typical) and breakdown voltage minimum (8.33V) must remain constant across substitute parts to ensure proper circuit protection thresholds.

Clamping Characteristics: The maximum clamping voltage at peak pulse current (Ipp) must be within acceptable limits for the protected circuit. The 5KP7.5CE3/TR13 specifies 14.3V maximum clamping.

Current and Power Ratings: Peak pulse current (350A at 10/1000µs waveform) and peak pulse power (5000W) define the transient energy absorption capability required for the application.

Package and Mounting: The P600 axial through-hole package is the physical form factor requirement. Substitute parts must maintain identical mechanical compatibility.

Temperature Range: Operating temperature range of -55°C to 175°C (junction temperature) must be maintained.

Compliance and Status: Active product status and RoHS3 compliance are required for current production applications.

The 5KP7.5CA from Littelfuse Inc. qualifies as a substitute based on matching voltage specifications, package type, temperature range, and compliance certifications, despite differences in clamping voltage and peak pulse current specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (5KP7.5CE3/TR13): Select this Microchip Technology component when sourcing from established inventory or when Microchip-specific supply chain requirements are mandated. The part is active in production, RoHS3 compliant, and carries REACH unaffected status. Packaging in tape and reel (TR) format is suitable for automated assembly processes.

Substitute Part (5KP7.5CA): The Littelfuse Inc. 5KP7.5CA provides equivalent functionality with identical voltage specifications and temperature range. This part is also active in production and maintains RoHS3 and REACH compliance. The cut tape (CT) packaging format differs from the primary part but maintains the same P600 axial through-hole mechanical interface. The 5KP7.5CA exhibits lower maximum clamping voltage (12.9V versus 14.3V) and higher peak pulse current capability (395.3A versus 350A), making it suitable for applications where tighter clamping control is beneficial.

Compliance Basis: Both parts satisfy RoHS3 requirements, REACH unaffected status, and MSL 1 (unlimited moisture sensitivity level), ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the 5KP7.5CA directly replace the 5KP7.5CE3/TR13 in existing designs?

A: Yes. Both parts share identical reverse standoff voltage (7.5V), breakdown voltage (8.33V minimum), operating temperature range (-55°C to 175°C), and P600 axial through-hole package. The mechanical and electrical interfaces are compatible. The 5KP7.5CA exhibits different clamping voltage and peak pulse current characteristics, which may provide improved performance in specific circuit topologies.

Q: What is the difference between tape and reel (TR) and cut tape (CT) packaging?

A: Tape and reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for high-volume automated assembly. Cut tape (CT) packaging provides components on cut segments of carrier tape, suitable for lower-volume applications or manual assembly. Both formats use identical P600 axial through-hole component geometry.

Q: Are there compliance differences between the two parts?

A: No. Both the 5KP7.5CE3/TR13 and 5KP7.5CA are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: How do the clamping voltage differences affect circuit protection?

A: The 5KP7.5CE3/TR13 specifies a maximum clamping voltage of 14.3V at peak pulse current, while the 5KP7.5CA specifies 12.9V. Lower clamping voltage provides tighter voltage regulation during transient events. Circuit design must verify that the protected component tolerates the clamping voltage of the selected TVS diode.

Q: What is the significance of the 10/1000µs waveform specification for peak pulse current?

A: The 10/1000µs waveform represents the standard test pulse shape for TVS diode characterization, with 10 microseconds rise time and 1000 microseconds pulse width. This specification defines the peak pulse current rating under standardized transient conditions. The 5KP7.5CE3/TR13 is rated for 350A and the 5KP7.5CA for 395.3A under this waveform.

Q: Can these parts be used for power line protection applications?

A: No. Both parts specify "No" for power line protection applications. These components are classified for general-purpose transient voltage suppression only.
