5KP13 Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 5KP13 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. The device features a 13V reverse standoff voltage rating and 5000W peak pulse power handling capability in a P600 axial through-hole package. The 5KP13 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 5KP13 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 13V
• Voltage - Clamping (Max) @ Ipp: Within acceptable tolerance for the application
• Power - Peak Pulse: 5000W (5kW)
• Package / Case: P600, Axial through-hole
• Type: Zener, Unidirectional
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• RoHS Compliance: ROHS3 Compliant

All identified substitute parts maintain the 13V reverse standoff voltage, 5000W peak pulse power rating, P600 axial package, and operating temperature range. Variations in clamping voltage and peak pulse current are within the electrical performance envelope for this device category. Substitute parts are classified as active products with current manufacturing status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

5KP13A (Littelfuse Inc.) is the primary direct substitute for the obsolete 5KP13. Both parts are manufactured by Littelfuse Inc., share identical voltage ratings and power specifications, and are housed in the same P600 axial package. The 5KP13A is actively produced and maintains ROHS3 compliance with unlimited moisture sensitivity level (MSL 1). This part provides the highest compatibility for direct replacement in existing designs.

SLD13U-017-B (Littelfuse Inc.) is an automotive-grade alternative within the Littelfuse product portfolio. It meets the same electrical specifications as the 5KP13A and carries AEC-Q101 automotive qualification. This part is suitable for applications requiring automotive-grade components and is actively manufactured with current inventory availability.

5KP13E3/TR13 (Microchip Technology) is a cross-manufacturer substitute manufactured by Microchip Technology. It maintains the 13V reverse standoff voltage and 5000W peak pulse power rating in the P600 axial package. The clamping voltage is 23.8V, which is within acceptable tolerance for general-purpose TVS applications. This part is actively produced and ROHS3 compliant, providing supply chain diversification from an alternative manufacturer.

All substitute parts maintain compliance with RoHS3 regulations and operate across the full -55°C to 175°C temperature range. Selection should be based on packaging requirements (Cut Tape, Tape & Reel, or Bulk), manufacturer preference, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 5KP13A directly replace the obsolete 5KP13 in existing circuit designs?

A: Yes. The 5KP13A maintains identical voltage ratings (13V reverse standoff), power specifications (5000W peak pulse), and package configuration (P600 axial through-hole). No circuit modifications are required for direct substitution.

Q: What is the difference between the 5KP13A and SLD13U-017-B?

A: Both parts share identical electrical specifications and package type. The SLD13U-017-B carries AEC-Q101 automotive qualification and is supplied in bulk packaging, while the 5KP13A is available in cut tape format. Selection depends on application requirements and packaging preferences.

Q: Is the 5KP13E3/TR13 from Microchip Technology electrically equivalent to the Littelfuse 5KP13A?

A: The 5KP13E3/TR13 maintains the same 13V reverse standoff voltage, 5000W peak pulse power rating, and P600 axial package. The clamping voltage is 23.8V compared to 21.5V for the 5KP13A. Both values are within acceptable operating parameters for general-purpose transient voltage suppression. The Microchip part provides cross-manufacturer compatibility.

Q: What packaging options are available for these substitute parts?

A: The 5KP13A is supplied in Cut Tape (CT) format. The SLD13U-017-B is available in Bulk packaging. The 5KP13E3/TR13 is supplied in Tape & Reel (TR) format. Selection should align with production assembly requirements and inventory management practices.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 5KP13A, SLD13U-017-B, and 5KP13E3/TR13 are all ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All substitute parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
