5KP24CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP24CE3/TR13 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This zener-type TVS diode features a 24V reverse standoff voltage with a 43V maximum clamping voltage and 116A peak pulse current capability. The device is packaged in a P600 axial through-hole configuration and supplied on tape and reel. The part maintains active product status and is ROHS3 compliant with unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to provide design flexibility, alternative sourcing options, and compatibility with different packaging formats while maintaining electrical performance within acceptable parameters for transient voltage suppression circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP24CE3/TR13 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Mandatory Matching Parameters:

• Voltage - Reverse Standoff (Typ): 24V
• Voltage - Breakdown (Min): 26.7V
• Power - Peak Pulse: 5000W
• Package / Case: P600, Axial
• Mounting Type: Through Hole
• Bidirectional Channels: 1
• Type: Zener
• Operating Temperature Range: -55°C to 175°C

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: Acceptable range 38.9V to 43V
• Current - Peak Pulse (10/1000µs): Acceptable range 116A to 131.1A
• Packaging Format: Tape & Reel (TR), Cut Tape (CT), or Bulk
• Manufacturer: Microchip Technology or Littelfuse Inc.

The substitute parts 5KP24CA, 5KP24CA-B, and SLD24-018 meet all mandatory matching parameters. Variations in clamping voltage and peak pulse current remain within acceptable operational limits for general-purpose transient voltage suppression. Packaging format differences do not affect electrical performance and allow for alternative procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (5KP24CA, 5KP24CA-B, and SLD24-018) are functionally equivalent to the 5KP24CE3/TR13 for general-purpose transient voltage suppression applications. Selection among these alternatives is based on the following criteria:

5KP24CA (Littelfuse, Cut Tape): This part is suitable for applications requiring standard packaging in cut tape format. It maintains full electrical equivalence with 38.9V clamping voltage and 131.1A peak pulse current. ROHS3 compliance and unlimited MSL rating ensure compatibility with standard manufacturing processes. This option provides the highest inventory availability at 4428 pieces.

5KP24CA-B (Littelfuse, Bulk): This variant offers the same electrical specifications as the 5KP24CA but in bulk packaging format. It is appropriate for high-volume production environments where bulk component handling is standard practice. Inventory availability is 1162 pieces. ROHS3 compliance and REACH unaffected status apply.

SLD24-018 (Littelfuse, Cut Tape, Automotive Grade): This part is qualified to AEC-Q101 automotive standards and carries automotive-grade designation. It is specified for applications requiring automotive-level reliability and traceability. The SLD24-018 carries REACH affected status, requiring compliance verification in regulated supply chains. Inventory availability is 6000 pieces, the highest among all options. This part is appropriate for automotive and mission-critical applications where AEC-Q101 qualification is a design requirement.

All substitute parts maintain active product status, ROHS3 compliance, and the full operating temperature range of -55°C to 175°C. Selection should be based on packaging format requirements, supply chain compliance obligations, and application-specific qualification standards.

Frequently Asked Questions (FAQ)

Q: Can the 5KP24CA be used as a direct replacement for the 5KP24CE3/TR13?

A: Yes. The 5KP24CA is electrically equivalent with matching reverse standoff voltage (24V), breakdown voltage (26.7V), power rating (5000W), and package type (P600 axial through-hole). The clamping voltage is 38.9V compared to 43V in the original part, and peak pulse current is 131.1A compared to 116A. These variations remain within acceptable operational limits for general-purpose transient voltage suppression. The primary difference is packaging format: the 5KP24CA is supplied in cut tape rather than tape and reel.

Q: What is the difference between the 5KP24CA and 5KP24CA-B?

A: Both parts are manufactured by Littelfuse and share identical electrical specifications: 24V reverse standoff voltage, 26.7V breakdown voltage, 38.9V clamping voltage, 131.1A peak pulse current, and 5000W power rating. The difference is packaging format. The 5KP24CA is supplied in cut tape (CT) format, while the 5KP24CA-B is supplied in bulk format. Electrical performance and component functionality are identical. Selection depends on assembly process requirements and inventory management practices.

Q: When should the SLD24-018 be selected over other substitute options?

A: The SLD24-018 is specified for applications requiring automotive-grade components with AEC-Q101 qualification. This part is appropriate for automotive electronics, safety-critical systems, and applications where automotive industry standards are mandatory. The SLD24-018 carries REACH affected status, which requires compliance verification in regulated supply chains. For non-automotive general-purpose applications, the 5KP24CA or 5KP24CA-B are appropriate alternatives without automotive qualification overhead.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts (5KP24CA, 5KP24CA-B, and SLD24-018) are ROHS3 compliant. The original 5KP24CE3/TR13 is also ROHS3 compliant. All parts carry unlimited moisture sensitivity level (MSL 1) rating, indicating no special moisture handling requirements during storage or assembly.

Q: What is the significance of REACH affected versus REACH unaffected status?

A: REACH affected status (SLD24-018) indicates the component may contain substances of concern regulated under the REACH directive and requires compliance documentation in certain supply chains, particularly in European markets. REACH unaffected status (5KP24CA, 5KP24CA-B, 5KP24CE3/TR13) indicates no regulated substances of concern are present. For applications with REACH compliance requirements, verify supply chain documentation. For applications without REACH obligations, both statuses are acceptable.

Q: Can the substitute parts handle the same transient voltage events as the original 5KP24CE3/TR13?

A: Yes. All substitute parts maintain the same 24V reverse standoff voltage and 26.7V minimum breakdown voltage, ensuring they respond to transient events at the same threshold. The clamping voltage variation (38.9V in substitutes versus 43V in original) and peak pulse current variation (131.1A in substitutes versus 116A in original) represent improved performance characteristics in the substitute parts. All parts are rated for 5000W peak pulse power, providing equivalent energy dissipation capability.

Q: Are there any temperature operating range differences between the parts?

A: No. All parts, including the original 5KP24CE3/TR13 and all three substitute options, operate across the identical temperature range of -55°C to 175°C (junction temperature). Temperature performance is fully equivalent across all options.
