5KP14CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP14CE3/TR13 is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This through-hole component features a 14V reverse standoff voltage with a 25.8V maximum clamping voltage and 5000W peak pulse power rating. The device is actively produced and ROHS3 compliant, making it suitable for modern electronic circuit protection requirements. Substitute parts are identified to provide alternative sourcing options when the primary component is unavailable or when procurement flexibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP14CE3/TR13 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for a valid substitution:

• Voltage - Reverse Standoff (Typ): 14V
• Voltage - Breakdown (Min): 15.6V
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Power - Peak Pulse: 5000W
• Operating Temperature Range: -55°C to 175°C (TJ)
• RoHS Status: ROHS3 Compliant

The 5KP14CA from Littelfuse Inc. meets all mandatory electrical and mechanical parameters for direct substitution. While the clamping voltage (23.2V) and peak pulse current (219.8A) differ from the main part, these variations remain within the functional tolerance band for the 14V standoff voltage class and do not preclude interchangeability in general-purpose protection circuits.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP14CE3/TR13 and 5KP14CA are active products with ROHS3 compliance and REACH unaffected status, confirming their suitability for current design implementations. The primary distinction between these components is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) format. This difference affects procurement and assembly workflows but does not impact electrical performance or circuit functionality.

The 5KP14CA exhibits a lower maximum clamping voltage (23.2V versus 25.8V) and higher peak pulse current capability (219.8A versus 194A). These characteristics remain within the operational envelope for 14V standoff voltage class TVS diodes and present no compatibility issues for general-purpose protection applications. Selection between these parts should be based on packaging availability, inventory status, and procurement lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5KP14CA be used as a direct replacement for the 5KP14CE3/TR13?

A: Yes. Both components share identical reverse standoff voltage (14V), breakdown voltage (15.6V), peak pulse power (5000W), through-hole mounting configuration, P600 axial package, and operating temperature range (-55°C to 175°C). The differences in clamping voltage and peak pulse current do not preclude interchangeability in general-purpose protection circuits.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape packaging provides components on tape segments cut to specified lengths, typically for manual assembly or lower-volume applications. Both formats contain identical components; the difference is in delivery and handling format only.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5KP14CE3/TR13 and 5KP14CA are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What does the 14V reverse standoff voltage indicate?

A: The 14V reverse standoff voltage specifies the maximum voltage the TVS diode can withstand in its normal operating state without conducting. When voltage exceeds the breakdown threshold (15.6V minimum), the device rapidly transitions to a low-impedance state, clamping the voltage to its maximum clamping level to protect downstream circuitry.

Q: Can these TVS diodes be used for power line protection?

A: No. Both components are designated for general-purpose applications and are not rated for power line protection. Power line protection applications require components specifically designed and certified for that purpose.

Q: What is the significance of the 5000W peak pulse power rating?

A: The 5000W peak pulse power rating indicates the maximum instantaneous power the TVS diode can dissipate during a 10/1000µs transient pulse event. This rating ensures the component can safely suppress transient overvoltage events without thermal damage or performance degradation.
