Equivalent & Substitute Parts for 5KP6.0-B TVS Diode

Part Overview

The 5KP6.0-B is a unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 6V reverse standoff voltage, 10.82V maximum clamping voltage, and 5000W peak pulse power rating in a through-hole P600 axial package. The part is currently listed as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for continued circuit protection functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP6.0-B is determined by the following critical parameters that must remain within acceptable tolerances:

• Voltage - Reverse Standoff: Must be 6V (identical)
• Voltage - Breakdown (Min): Must be within the 6V class specification (6.32V to 6.67V acceptable)
• Voltage - Clamping (Max) @ Ipp: Must not exceed 11.4V to maintain circuit protection integrity
• Power - Peak Pulse: Must be 5000W (5kW) minimum
• Mounting Type: Must be Through Hole
• Package / Case: Must be P600 Axial or equivalent axial package
• Type: Must be Zener unidirectional TVS diode

All identified substitute parts meet these criteria and are classified as either direct equivalents or manufacturer-recommended alternatives.

Parameter Comparison

Engineering Selection Recommendations

5KP6.0A-B (Littelfuse Inc.) is the primary substitute for the 5KP6.0-B. Both parts are manufactured by Littelfuse Inc., share identical ROHS3 compliance status, operate across the full -55 to 175°C temperature range, and use the P600 axial package. The 5KP6.0A-B maintains the same reverse standoff voltage (6V) and demonstrates superior peak pulse current capability (495.1A versus unspecified for the main part). The clamping voltage is reduced to 10.3V, providing enhanced circuit protection margins.

5KP6.0A (EIC Semiconductor Inc.) is a direct functional equivalent with identical electrical specifications to the 5KP6.0A-B. This part is RoHS compliant and rated for -55 to 150°C operation. The D-6 axial package is mechanically compatible with P600 footprints in through-hole applications. Peak pulse current is specified at 485A.

5KP6.0E3/TR13 (Microchip Technology) is the manufacturer-recommended alternative. This part maintains full parameter compatibility with a maximum clamping voltage of 11.4V, operates across -55 to 175°C, and is ROHS3 compliant. The Tape & Reel packaging format is suitable for automated assembly environments. Peak pulse current is rated at 439A.

All three substitute parts satisfy the critical substitution criteria: 6V reverse standoff voltage, 5000W peak pulse power, through-hole mounting, and axial package configuration.

Frequently Asked Questions (FAQ)

Q: Can the 5KP6.0A be used as a direct replacement for the 5KP6.0-B in existing PCB designs?

A: Yes. The 5KP6.0A maintains identical reverse standoff voltage (6V), peak pulse power (5000W), and through-hole axial package compatibility. The D-6 package footprint is mechanically equivalent to P600 for through-hole applications. The primary consideration is the reduced operating temperature range (-55 to 150°C versus -55 to 175°C), which may affect suitability in high-temperature environments.

Q: What is the difference between the 5KP6.0A-B and 5KP6.0A?

A: Both parts are functionally equivalent with identical electrical specifications (6V standoff, 10.3V clamping, 5000W power). The 5KP6.0A-B is manufactured by Littelfuse Inc. and operates to 175°C in a P600 package. The 5KP6.0A is manufactured by EIC Semiconductor Inc., operates to 150°C, and uses a D-6 package. Selection depends on temperature requirements and preferred manufacturer.

Q: Why does the 5KP6.0E3/TR13 have a higher clamping voltage (11.4V) than the main part (10.82V)?

A: The 5KP6.0E3/TR13 remains within the 6V reverse standoff class specification and meets all substitution criteria. The slightly higher clamping voltage (11.4V) is within acceptable tolerance for the 5KP6 series and does not compromise circuit protection functionality. This part is manufacturer-recommended by Microchip Technology.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 5KP6.0A-B and 5KP6.0E3/TR13 are ROHS3 compliant. The 5KP6.0A is RoHS compliant. All parts meet environmental compliance requirements for current manufacturing standards.

Q: What packaging formats are available for these substitutes?

A: The 5KP6.0A-B is available in Bulk packaging. The 5KP6.0A is supplied in Bag format. The 5KP6.0E3/TR13 is available in Tape & Reel (TR) format for automated assembly. Selection depends on production volume and assembly methodology.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes, within the specified electrical and thermal operating parameters. All substitute parts maintain the 6V reverse standoff voltage and 5000W peak pulse power rating. Verify that the operating temperature range of the selected substitute matches your application requirements, particularly for the 5KP6.0A, which is limited to 150°C maximum junction temperature.
