5KP13CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP13CE3/TR13 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This through-hole component operates across a wide temperature range of -55°C to 175°C and is rated for 5000W peak pulse power dissipation. The part is currently in active production status and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific inventory requirements necessitate alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP13CE3/TR13 are qualified based on the following critical parameters that determine functional equivalence:

Voltage Parameters: Reverse standoff voltage of 13V, minimum breakdown voltage of 14.4V, and maximum clamping voltage specifications must remain within acceptable tolerance for the protected circuit.

Current and Power Ratings: Peak pulse current capability and 5000W peak pulse power dissipation capacity establish the transient energy handling threshold.

Physical Compatibility: Through-hole mounting type and P600 axial package configuration ensure mechanical fit within existing PCB designs.

Environmental and Compliance Requirements: Operating temperature range of -55°C to 175°C, RoHS3 compliance, and MSL 1 rating must be maintained.

Bidirectional Protection: Single-channel bidirectional configuration for symmetric overvoltage suppression.

The 5KP13CA from Littelfuse Inc. qualifies as a substitute part because it maintains identical specifications for reverse standoff voltage, breakdown voltage, power rating, temperature range, package type, and compliance certifications. Variations in clamping voltage (21.5V versus 23.8V) and peak pulse current (237.2A versus 210A) remain within the functional tolerance band for general-purpose TVS applications.

Engineering Selection Recommendations

Primary Part Selection: The 5KP13CE3/TR13 remains the preferred choice when available, as it is the specified component in the original design and maintains full active production status with established supply chain documentation.

Substitute Part Selection: The 5KP13CA from Littelfuse Inc. is a qualified substitute when the primary part is unavailable. Both parts maintain identical compliance certifications (RoHS3, REACH Unaffected) and environmental ratings (MSL 1, -55°C to 175°C operating range). The substitute part demonstrates superior peak pulse current capability (237.2A versus 210A), providing enhanced transient handling margin. The clamping voltage differential (21.5V versus 23.8V) represents a 9.7% reduction, which remains acceptable for general-purpose protection applications where the 13V standoff voltage and 14.4V minimum breakdown threshold are the primary design constraints.

Packaging Consideration: The primary part is supplied in Tape & Reel (TR) packaging, while the substitute is supplied in Cut Tape (CT) packaging. Both packaging formats are compatible with standard through-hole assembly processes and do not affect electrical performance or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can the 5KP13CA be used as a direct replacement for the 5KP13CE3/TR13?

A: Yes. Both parts share identical reverse standoff voltage (13V), breakdown voltage (14.4V), peak pulse power rating (5000W), operating temperature range (-55°C to 175°C), package type (P600 axial), and compliance certifications (RoHS3, REACH Unaffected). The parts are functionally equivalent for general-purpose TVS applications.

Q: What is the significance of the clamping voltage difference between the two parts?

A: The 5KP13CE3/TR13 clamps at 23.8V maximum, while the 5KP13CA clamps at 21.5V maximum. This 2.3V difference represents a 9.7% variation. For circuits designed around the 13V standoff specification, both clamping voltages provide adequate protection margin and remain within acceptable operating parameters for general-purpose applications.

Q: Does the higher peak pulse current of the 5KP13CA affect compatibility?

A: No. The 5KP13CA's peak pulse current rating of 237.2A exceeds the 5KP13CE3/TR13 specification of 210A. This represents enhanced capability and does not compromise compatibility. Both parts are rated for identical 5000W peak pulse power dissipation.

Q: Are there packaging differences that affect assembly?

A: The primary part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format. Both formats are compatible with standard through-hole assembly equipment and processes. No design or assembly modifications are required.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the 5KP13CE3/TR13 and 5KP13CA are RoHS3 compliant, REACH unaffected, and rated MSL 1 (unlimited moisture sensitivity). Both operate across the identical temperature range of -55°C to 175°C.

Q: What is the base product number for these parts?

A: The 5KP13CE3/TR13 has a base product number of 5KP13, while the 5KP13CA has a base product number of 5KP1. Both designations refer to the same 13V rating class within their respective manufacturer product lines.
