3KP130C-B Equivalent & Substitute Parts

Part Overview

The 3KP130C-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This bidirectional Zener diode features a 130V reverse standoff voltage and 219.45V maximum clamping voltage with 14.4A peak pulse current capability in a P600 axial through-hole package. The part is currently obsolete, necessitating identification of functionally equivalent alternatives from active product lines that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 3KP130C-B is determined by the following critical parameters:

Voltage - Reverse Standoff: Must be 130V (exact match required for circuit protection threshold)
Mounting Type: Must be Through Hole (PCB assembly compatibility)
Type: Must be Zener (functional classification)
Bidirectional Channels: Must be 1 (single-channel protection)
Operating Temperature Range: Must encompass -55°C ~ 175°C (thermal operating envelope)
Package Compatibility: P600 axial or equivalent mechanical footprint

Substitute parts are grouped into two categories based on package type: P600 axial (direct mechanical replacement) and R-6 axial (alternative axial package requiring mechanical verification). Electrical parameters including clamping voltage, peak pulse current, and power dissipation may vary within the 130V standoff voltage class, as these represent performance enhancements or deratings that do not prevent functional substitution in general-purpose applications.

Engineering Selection Recommendations

P600 Axial Package (Direct Mechanical Replacement):

The 5KP130CA-B (Littelfuse Inc.) and 5KP130CAE3/TR13 (Microchip Technology) are active-status alternatives maintaining identical P600 axial packaging. Both parts meet the 130V reverse standoff requirement and operating temperature specification. The 5KP130CA-B provides higher peak pulse current (24.4A) and power dissipation (5000W) compared to the original 3KP130C-B, representing a performance upgrade within the same voltage class. The 15KPA130CAE3/TR13 (Microchip Technology) offers the highest power rating (15000W) and peak pulse current (72.5A) for applications requiring enhanced transient suppression capability.

R-6 Axial Package (Alternative Axial Configuration):

The 3KP130CA-TP (Micro Commercial Co) maintains the original 3000W power rating and 14.4A peak pulse current with identical electrical performance but uses an R-6 axial package. The 5KP130CA-TP (Micro Commercial Co) provides 5000W power rating in R-6 configuration. Both R-6 alternatives require mechanical footprint verification before implementation.

All substitute parts are RoHS3 compliant and operate within the -55°C ~ 175°C temperature range specified for the original part.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 3KP130C-B with any of the listed alternatives?

A: Substitution is valid only when the replacement part maintains the 130V reverse standoff voltage, through-hole mounting type, and operating temperature range of -55°C ~ 175°C. Package type (P600 or R-6 axial) must be verified for PCB compatibility.

Q: What is the difference between P600 and R-6 axial packages?

A: Both are through-hole axial packages for TVS diodes. P600 is the original package type used in the 3KP130C-B. R-6 is an alternative axial configuration. Physical dimensions and PCB hole spacing may differ; verify mechanical compatibility before substitution.

Q: Why do some substitute parts have higher power ratings?

A: The 5KP and 15KPA series represent higher power-rated variants within the 130V voltage class. These parts provide enhanced transient suppression capability (higher peak pulse current and power dissipation) while maintaining the same reverse standoff voltage. They are functionally compatible for general-purpose protection applications.

Q: Are all substitute parts currently available?

A: All listed substitute parts have active product status. The original 3KP130C-B is obsolete. Availability should be confirmed with component distributors.

Q: What does "Bidirectional Channels: 1" mean?

A: This indicates the TVS diode provides single-channel bidirectional protection, suppressing transients in both forward and reverse polarity directions on a single line.

Q: Do I need to change my circuit design to use a substitute part?

A: No. All substitute parts maintain the 130V reverse standoff voltage and through-hole mounting type. Electrical performance may improve (higher current/power ratings) but will not degrade circuit protection function in general-purpose applications.
