5KP130C Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 5KP130C is a bidirectional Zener transient voltage suppressor diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. Rated at 130V reverse standoff voltage with 5000W peak pulse power handling, this component operates across -55°C to 175°C. The 5KP130C is classified as obsolete, necessitating identification of active equivalent and substitute parts that maintain electrical and mechanical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP130C is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): Must equal 130V
• Type: Must be Zener bidirectional TVS diode
• Bidirectional Channels: Must equal 1
• Mounting Type: Must be Through Hole
• Power - Peak Pulse: Must equal or exceed 5000W
• Operating Temperature Range: Must support -55°C to 175°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status

Substitute parts are grouped into two categories based on package compatibility:

Category A - P600 Package (Direct Mechanical Fit): Parts maintaining the original P600 axial package allow direct board-level replacement without layout modification.

Category B - R-6 Package (Alternative Mechanical Form): Parts using R-6 axial package provide electrical equivalence but require board layout adjustment due to different physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for Direct Replacement)

5KP130CA (Littelfuse Inc.) and 5KP130CAE3/TR13 (Microchip Technology) are the preferred direct substitutes. Both maintain P600 axial packaging, identical 130V reverse standoff voltage, 5000W peak pulse power, and full -55°C to 175°C operating temperature range. Both are active products with ROHS3 compliance. These parts require no board layout modification and provide seamless electrical compatibility.

Secondary Substitutes (Package Variant - R-6 Axial)

5KP130CA-TP (Micro Commercial Co) and 5KP130CA-G (Comchip Technology) provide electrical equivalence with identical voltage and power ratings but use R-6 axial packaging. Board layout modification is required. 5KP130CA-TP supports the full -55°C to 175°C temperature range, while 5KP130CA-G is limited to -55°C to 150°C. Both are active products with appropriate compliance certifications.

Alternative Power Ratings (Specialized Applications)

3KP130CA-TP provides reduced 3000W peak pulse power for applications with lower transient energy requirements. 15KP130CA-TP provides elevated 15000W peak pulse power for high-energy transient protection. Both use R-6 packaging and maintain 130V voltage specifications. Selection depends on actual circuit transient energy levels.

Automotive Grade Option

A5KP130CA-G (Comchip Technology) is AEC-Q101 qualified for automotive applications, using R-6 packaging with -55°C to 150°C operating range. This part is suitable only for automotive designs requiring automotive-grade component certification.

Frequently Asked Questions (FAQ)

Q: Can 5KP130CA directly replace 5KP130C without board modification?

A: Yes. 5KP130CA maintains identical P600 axial packaging, 130V reverse standoff voltage, 5000W peak pulse power, and -55°C to 175°C operating temperature. No board layout changes are required.

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

A: Both are axial through-hole packages for TVS diodes. P600 and R-6 differ in physical dimensions and lead spacing. Parts using R-6 packaging require board layout modification compared to the original P600 design.

Q: Can I use 3KP130CA-TP as a substitute if my circuit has lower transient energy?

A: 3KP130CA-TP is electrically compatible with 130V reverse standoff voltage and identical clamping characteristics. However, its 3000W peak pulse power rating is below the original 5000W specification. Use only if circuit analysis confirms transient energy does not exceed 3000W.

Q: Is 15KP130CA-TP suitable for all applications requiring 5KP130C?

A: 15KP130CA-TP provides higher 15000W peak pulse power capability, maintaining 130V voltage specifications and R-6 packaging. It is suitable for applications requiring enhanced transient protection. Board layout modification is required due to R-6 packaging.

Q: What is the temperature limitation of 5KP130CA-G compared to other substitutes?

A: 5KP130CA-G operates across -55°C to 150°C, which is 25°C below the original 5KP130C specification of -55°C to 175°C. Use only in applications where maximum junction temperature does not exceed 150°C.

Q: Is A5KP130CA-G suitable for non-automotive applications?

A: A5KP130CA-G is AEC-Q101 automotive-qualified. While electrically compatible, it is specified for automotive use. For non-automotive applications, standard industrial-grade substitutes (5KP130CA, 5KP130CAE3/TR13) are appropriate.

Q: Do all substitute parts maintain ROHS3 compliance?

A: 5KP130CA, 5KP130CAE3/TR13, 5KP130CA-G, 5KP130CA-TP, and A5KP130CA-G are ROHS3 compliant. 3KP130CA-TP and 15KP130CA-TP do not specify RoHS status in available documentation.
