3KP130C Equivalent & Substitute Parts

Part Overview

The 3KP130C is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage protection applications. This component features a 130V reverse standoff voltage with a 219.45V maximum clamping voltage and 14.4A peak pulse current capability. The 3KP130C is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3KP130C are qualified based on the following critical parameters:

• Voltage - Reverse Standoff (Typ): 130V
• Voltage - Clamping (Max) @ Ipp: Within acceptable range for circuit protection
• Current - Peak Pulse (10/1000µs): Equal to or greater than 14.4A
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Type: Zener
• Bidirectional Channels: 1

The identified substitutes meet these core electrical and mechanical requirements, ensuring functional compatibility in the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both 5KP130CA and 5KP130CAE3/TR13 are active-status alternatives to the obsolete 3KP130C. The 5KP130CA offers higher peak pulse current (24.4A versus 14.4A) and increased power dissipation capability (5000W versus 3000W), providing enhanced protection margins in the same P600 axial package. The 5KP130CAE3/TR13 is the manufacturer-recommended substitute, supplied by Microchip Technology in Tape & Reel packaging format.

Both substitutes maintain identical reverse standoff voltage (130V), operating temperature range (-55°C ~ 175°C), and package configuration, ensuring direct mechanical and electrical compatibility. All parts comply with ROHS3 and carry MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can 5KP130CA directly replace 3KP130C in existing designs?

A: Yes. Both parts share identical reverse standoff voltage (130V), operating temperature range, and P600 axial package configuration. The 5KP130CA provides superior performance with higher peak pulse current (24.4A) and power dissipation (5000W).

Q: What is the difference between 5KP130CA and 5KP130CAE3/TR13?

A: Both parts have identical electrical specifications. The primary difference is packaging: 5KP130CA is supplied in Cut Tape format, while 5KP130CAE3/TR13 is supplied in Tape & Reel format. Selection depends on procurement and assembly requirements.

Q: Are there any compliance differences between the substitutes?

A: No. All three parts (3KP130C, 5KP130CA, and 5KP130CAE3/TR13) are ROHS3 compliant with MSL 1 rating and identical operating temperature specifications.

Q: Why does 5KP130CA have higher peak pulse current than 3KP130C?

A: The 5KP series represents an enhanced product line with improved performance characteristics. The higher current rating (24.4A) and power dissipation (5000W) provide additional protection margin without affecting core voltage parameters required for substitution.

Q: Is the P600 axial package identical across all three parts?

A: Yes. All three parts use the P600 axial through-hole package, ensuring identical mechanical fit and PCB layout compatibility.
