5KP130 Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 5KP130 is a unidirectional Zener-type transient voltage suppressor diode manufactured by Littelfuse, designed for general-purpose voltage clamping applications. This component features a 130V reverse standoff voltage rating and 5000W peak pulse power handling capability in a through-hole P600 axial package. The 5KP130 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

The 5KP130A qualifies as a direct substitute for the 5KP130 based on the following critical electrical and mechanical parameters:

Substitution Criteria:

• Identical reverse standoff voltage: 130V
• Identical unidirectional channel configuration: 1 channel
• Identical power rating: 5000W peak pulse
• Identical package type: P600 axial through-hole
• Identical operating temperature range: -55°C ~ 175°C
• Same series designation: 5KP
• Identical RoHS3 compliance status

The 5KP130A maintains functional equivalence while offering active product status and improved availability. Voltage breakdown and clamping specifications remain within acceptable tolerance ranges for general-purpose transient suppression applications.

Parameter Comparison

Engineering Selection Recommendations

The 5KP130A is the appropriate substitute for the obsolete 5KP130. Both components maintain identical electrical ratings for reverse standoff voltage, power dissipation, and thermal operating range. The 5KP130A carries active product status with confirmed inventory availability and ROHS3 compliance certification, ensuring long-term supply chain viability and regulatory alignment.

The 5KP130A exhibits lower clamping voltage (209V vs. 219.45V) and higher minimum breakdown voltage (144V vs. 136.35V), both of which represent improved performance characteristics within the 5KP series design envelope. These variations fall within normal manufacturing tolerance ranges for TVS diodes and do not compromise functional compatibility in general-purpose transient suppression circuits.

Frequently Asked Questions (FAQ)

Q: Can the 5KP130A directly replace the 5KP130 in existing designs?

A: Yes. The 5KP130A maintains identical reverse standoff voltage (130V), power rating (5000W), package configuration (P600 axial), and operating temperature range (-55°C to 175°C). Both components are unidirectional Zener-type TVS diodes suitable for general-purpose applications.

Q: What is the primary reason for substitution?

A: The 5KP130 is classified as obsolete. The 5KP130A is the active equivalent offering continued availability, confirmed inventory stock, and identical functional specifications.

Q: Are there packaging differences between these parts?

A: The 5KP130A is supplied in Cut Tape (CT) packaging, while the original 5KP130 packaging format is not specified. Both use the same P600 axial through-hole package case, ensuring mechanical and electrical compatibility on printed circuit boards.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 5KP130 and 5KP130A are ROHS3 compliant. The 5KP130A additionally carries REACH Unaffected status.

Q: What are the voltage specification differences?

A: The 5KP130A exhibits a clamping voltage of 209V compared to 219.45V for the 5KP130, and a minimum breakdown voltage of 144V versus 136.35V. These differences represent normal parameter variation within the 5KP series and do not affect substitution suitability for general-purpose transient suppression.

Q: Is the 5KP130A-TP a further substitute option?

A: The 5KP130A-TP is listed as a substitute for the 5KP130A. Consult the 5KP130A technical documentation for compatibility details regarding this variant.
