SLD13-018-B Equivalent & Substitute Parts

Part Overview

The SLD13-018-B is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Littelfuse, designed for through-hole mounting in P600 axial package configuration. This component provides transient overvoltage protection with a 13V reverse standoff voltage and 21.5V maximum clamping voltage at peak pulse current. The part is classified as Active product status with AEC-Q101 automotive qualification and ROHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLD13-018-B is determined by matching the following critical parameters:

• Voltage - Reverse Standoff (Typ): 13V
• Voltage - Breakdown (Min): 14.4V
• Voltage - Clamping (Max) @ Ipp: 21.5V
• Current - Peak Pulse (10/1000µs): 237.2A
• Power - Peak Pulse: 5000W
• Package / Case: P600, Axial
• Mounting Type: Through Hole
• Bidirectional Channels: 1
• Operating Temperature Range: -55°C to 175°C

The 5KP13CA meets all specified electrical and mechanical parameters, maintaining identical voltage ratings, peak pulse current capacity, and power dissipation capability. Both components utilize the same P600 axial through-hole package, ensuring direct mechanical compatibility in circuit board layouts.

Parameter Comparison

Engineering Selection Recommendations

Both the SLD13-018-B and 5KP13CA are Active product status components manufactured by Littelfuse with identical electrical specifications and mechanical packaging. Selection between these parts may be based on packaging format availability: the SLD13-018-B is supplied in Bulk packaging, while the 5KP13CA is available in Cut Tape (CT) format. Both components carry ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements. The AEC-Q101 automotive qualification specified for the SLD13-018-B should be verified for the 5KP13CA if automotive-grade certification is a system requirement.

Frequently Asked Questions (FAQ)

Q: Can the 5KP13CA directly replace the SLD13-018-B in existing circuit designs?

A: Yes. Both components share identical electrical parameters (13V reverse standoff, 21.5V clamping voltage, 237.2A peak pulse current, 5000W power rating) and are packaged in the same P600 axial through-hole configuration. Direct pin-for-pin substitution is mechanically and electrically compatible.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies components loose in a container, suitable for manual assembly or reel winding. Cut Tape (CT) packaging provides components on adhesive tape in cut lengths, optimized for automated pick-and-place assembly equipment. Electrical and mechanical specifications remain identical.

Q: Are both parts suitable for automotive applications?

A: The SLD13-018-B carries AEC-Q101 automotive qualification. The 5KP13CA specifications provided do not explicitly list AEC-Q101 certification. Verify automotive qualification requirements with the manufacturer or component datasheet if this certification is mandatory for your application.

Q: Do these TVS diodes require any special handling or storage conditions?

A: Both components have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard electronic component storage practices apply.

Q: What is the operating temperature range for both parts?

A: Both the SLD13-018-B and 5KP13CA operate across -55°C to 175°C junction temperature range, suitable for industrial and automotive temperature environments.
