5KP13C-B Equivalent & Substitute Parts

Part Overview

The 5KP13C-B is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse, designed for general-purpose overvoltage protection applications. This component features a 13V reverse standoff voltage, 22.58V maximum clamping voltage, and 5000W peak pulse power rating in a P600 axial through-hole package. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP13C-B is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 13V (all substitutes maintain this specification)
• Bidirectional Channels: 1 (single channel configuration required)
• Power - Peak Pulse: 5000W (5kW) (all substitutes rated identically)
• Mounting Type: Through Hole (mechanical compatibility)
• Package / Case: P600, Axial (physical form factor)
• Operating Temperature Range: -55°C ~ 175°C (TJ) (all substitutes support this range)
• RoHS Status: ROHS3 Compliant (regulatory compliance maintained)

The substitute parts listed below satisfy all mandatory electrical and mechanical parameters. Variations in clamping voltage (21.5V to 23.8V) and peak pulse current remain within acceptable tolerance bands for general-purpose TVS applications while maintaining the core 13V standoff specification and 5kW power rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Littelfuse 5KP Series)

The 5KP13CA and 5KP13CA-B are direct Littelfuse equivalents with active product status. Both maintain identical electrical specifications (13V standoff, 5kW power rating, -55°C to 175°C operating range) and P600 axial package compatibility. Selection between these two depends on procurement requirements: 5KP13CA is supplied in Cut Tape packaging, while 5KP13CA-B is supplied in Bulk packaging. Both are ROHS3 compliant with unlimited moisture sensitivity level.

Automotive-Grade Alternative (SLD13-018-B)

The SLD13-018-B is a Littelfuse automotive-qualified TVS diode (AEC-Q101 certified) with identical electrical and mechanical specifications to the 5KP13CA series. This part is suitable for applications requiring automotive-grade component qualification while maintaining full electrical compatibility.

Cross-Manufacturer Alternative (5KP13CE3/TR13)

The 5KP13CE3/TR13 from Microchip Technology provides equivalent functionality with a slightly higher clamping voltage (23.8V versus 21.5V) and lower peak pulse current (210A versus 237.2A). This part maintains the 13V standoff voltage, 5kW power rating, and identical operating temperature range. Selection of this cross-manufacturer part is appropriate when Microchip supply chain availability is preferred or when the higher clamping voltage specification is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 5KP13C-B with 5KP13CA in my circuit?

A: Yes. Both parts share identical reverse standoff voltage (13V), power rating (5kW), operating temperature range (-55°C to 175°C), and P600 axial package configuration. The primary difference is product status: 5KP13C-B is obsolete while 5KP13CA is active. Electrical performance is equivalent for general-purpose TVS applications.

Q: What is the difference between 5KP13CA and 5KP13CA-B?

A: These parts are electrically identical. The difference is packaging: 5KP13CA is supplied in Cut Tape (CT) format, while 5KP13CA-B is supplied in Bulk format. Selection depends on your procurement and assembly process requirements.

Q: Can I use SLD13-018-B as a substitute?

A: Yes. The SLD13-018-B is electrically and mechanically equivalent to 5KP13CA and 5KP13CA-B. The primary distinction is automotive-grade qualification (AEC-Q101 certified). Use this part if your application requires automotive-grade component certification or if automotive supply chain availability is preferred.

Q: Is the Microchip 5KP13CE3/TR13 a suitable replacement?

A: Yes, with specification awareness. The 5KP13CE3/TR13 maintains the 13V standoff voltage, 5kW power rating, and identical operating temperature range. The clamping voltage is slightly higher (23.8V versus 21.5V) and peak pulse current is lower (210A versus 237.2A). This part is suitable when cross-manufacturer sourcing is acceptable and the higher clamping voltage specification is compatible with your circuit design.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (5KP13CA, 5KP13CA-B, SLD13-018-B, and 5KP13CE3/TR13) are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), matching the compliance status of the original 5KP13C-B.

Q: What packaging options are available for these substitutes?

A: Littelfuse offers 5KP13CA in Cut Tape (CT) packaging and 5KP13CA-B in Bulk packaging. The SLD13-018-B is supplied in Bulk format. The Microchip 5KP13CE3/TR13 is supplied in Tape & Reel (TR) format. All maintain the same P600 axial through-hole package configuration.
