5KP6.0A-B Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 5KP6.0A-B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This through-hole component operates across a wide temperature range and provides peak pulse power handling of 5000W. The part is currently in active production status with robust inventory availability. Equivalent and substitute parts are identified based on matching electrical performance characteristics and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP6.0A-B are qualified based on the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 6V
• Voltage - Clamping (Max) @ Ipp: 10.3V
• Power - Peak Pulse: 5000W (5kW)
• Unidirectional Channels: 1
• Mounting Type: Through Hole
• Type: Zener

The identified substitutes maintain these core specifications while operating within acceptable tolerances for peak pulse current and temperature ranges. Package variations (P600, D-6, R-6) represent different axial through-hole configurations suitable for equivalent circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with RoHS requirements. The 5KP6.0A-B (Littelfuse) and 5KP6.0A-TP (Micro Commercial Co) both support the full operating temperature range of -55°C to 175°C, making them suitable for applications requiring extended thermal performance. The 5KP6.0A (EIC Semiconductor) operates to 150°C maximum junction temperature and carries automotive-grade qualification.

Selection between these substitutes depends on packaging requirements and supply chain considerations. The P600, D-6, and R-6 packages are all axial through-hole configurations with different physical footprints. Peak pulse current specifications are provided for the Littelfuse and EIC parts (495.1A and 485A respectively), with the Micro Commercial Co part not specifying this parameter in available documentation.

Frequently Asked Questions (FAQ)

Q: Can 5KP6.0A-TP replace 5KP6.0A-B in all applications?

A: Yes, provided the physical package footprint (R-6 vs P600) is compatible with the circuit board layout. Both parts maintain identical voltage ratings (6V standoff, 10.3V clamping) and 5000W peak pulse power handling.

Q: What is the difference between the package types P600, D-6, and R-6?

A: These designations represent different axial through-hole package configurations. All are suitable for through-hole mounting on printed circuit boards. Physical dimensions and lead spacing differ between packages, requiring verification against board design specifications.

Q: Does the operating temperature difference between 150°C and 175°C affect substitution?

A: The 5KP6.0A (EIC Semiconductor) is rated to 150°C maximum junction temperature, while 5KP6.0A-B and 5KP6.0A-TP are rated to 175°C. For applications operating near or above 150°C, the EIC part may not be suitable. For standard operating conditions below 150°C, all three parts are functionally equivalent.

Q: Are there packaging format considerations for procurement?

A: Yes. The 5KP6.0A-B is supplied in Bulk packaging, 5KP6.0A in Bag format, and 5KP6.0A-TP in Cut Tape (CT). Packaging format affects handling, storage, and automated assembly compatibility. Verify procurement and assembly requirements before selection.

Q: What does the peak pulse current specification indicate?

A: Peak pulse current (10/1000µs) indicates the maximum current the device can handle during a transient event. The 5KP6.0A-B handles 495.1A and the 5KP6.0A handles 485A. Both values support the 5000W peak pulse power rating at the specified voltage clamping level.
