Equivalent & Substitute Parts for 5KP13C TVS Diode

Part Overview

The 5KP13C is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 13V reverse standoff voltage, 5000W peak pulse power rating, and P600 axial through-hole packaging. The 5KP13C is currently listed as obsolete, necessitating identification of functionally equivalent substitute components that maintain electrical and mechanical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP13C are qualified based on the following critical parameters that determine functional equivalence:

• Voltage - Reverse Standoff (Typ): 13V
• Power - Peak Pulse: 5000W (5kW)
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• RoHS Status: ROHS3 Compliant

The substitute parts identified maintain these core electrical and mechanical specifications. Variations in voltage clamping characteristics and peak pulse current are within acceptable ranges for TVS diode substitution, as these parameters reflect manufacturing process variations and design iterations within the same product family.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (5KP13CA, SLD13-018-B, and 5KP13CE3/TR13) are currently in active production status, providing supply continuity for applications previously using the obsolete 5KP13C.

5KP13CA is a direct Littelfuse equivalent available in Cut Tape packaging with 2300 units in stock inventory. This part maintains identical electrical specifications to the main part and represents the primary substitution path for existing designs.

SLD13-018-B is a Littelfuse automotive-grade TVS diode qualified to AEC-Q101 standard, available in Bulk packaging. This part is suitable for applications requiring automotive-grade components and offers the same electrical performance as 5KP13CA.

5KP13CE3/TR13 is manufactured by Microchip Technology and supplied in Tape & Reel packaging. This part maintains the 13V reverse standoff voltage and 5000W power rating, with a clamping voltage of 23.8V, which is within acceptable variation for TVS diode applications.

Frequently Asked Questions (FAQ)

Q: Can 5KP13CA directly replace 5KP13C in existing designs? A: Yes. The 5KP13CA maintains identical reverse standoff voltage (13V), power rating (5000W), operating temperature range (-55°C to 175°C), and P600 axial through-hole packaging. The primary difference is product status (Active vs. Obsolete) and packaging format (Cut Tape vs. standard).

Q: What is the difference between 5KP13CA and SLD13-018-B? A: Both parts share identical electrical specifications (13V standoff, 5000W power, 21.5V clamping voltage). SLD13-018-B carries automotive-grade qualification (AEC-Q101) and is supplied in Bulk packaging, while 5KP13CA is supplied in Cut Tape. Selection depends on application requirements and packaging preferences.

Q: Is 5KP13CE3/TR13 from Microchip Technology compatible with the original 5KP13C? A: Yes. The 5KP13CE3/TR13 maintains the critical electrical parameters: 13V reverse standoff voltage, 5000W peak pulse power, -55°C to 175°C operating temperature, and P600 axial through-hole packaging. The clamping voltage is 23.8V compared to 22.58V in the original part, which is within acceptable TVS diode variation.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All three substitute parts (5KP13CA, SLD13-018-B, and 5KP13CE3/TR13) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What packaging options are available for substitutes? A: 5KP13CA is available in Cut Tape (CT) packaging, SLD13-018-B in Bulk packaging, and 5KP13CE3/TR13 in Tape & Reel (TR) packaging. All maintain identical P600 axial through-hole form factor for PCB mounting.
