TLP24CA Equivalent & Substitute Parts

Part Overview

The TLP24CA is a high-reliability transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage clamping applications. This bidirectional zener TVS operates with a 24V reverse standoff voltage and provides peak pulse current handling of 131.1A with a maximum clamping voltage of 38.9V. The device is housed in a P600 axial through-hole package and maintains active product status with full RoHS3 and REACH 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

Substitute parts for the TLP24CA are qualified based on the following critical parameters:

• Voltage - Reverse Standoff (Typ): 24V
• Voltage - Clamping (Max) @ Ipp: 38.9V
• Bidirectional operation with single channel
• Through-hole axial mounting configuration
• Operating temperature range: -55°C to 175°C (TJ)
• Zener type TVS diode classification

The 6KPE24CAH from Eaton - Electronics Division meets these core electrical specifications while maintaining mechanical compatibility through identical voltage ratings and axial through-hole packaging. Variations in peak pulse current (169.7A vs. 131.1A) and power dissipation (6.6kW vs. 5kW) represent enhanced performance characteristics that do not preclude substitution in applications designed for the TLP24CA baseline specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TLP24CA and 6KPE24CAH maintain active product status and are suitable for general-purpose TVS applications requiring 24V clamping. The TLP24CA carries explicit RoHS3 compliance certification. The 6KPE24CAH is qualified to AEC-Q101 automotive standards and carries automotive-grade designation, making it appropriate for applications with automotive qualification requirements.

Selection between these parts should be based on:

• Supply chain availability and lead time requirements
• Packaging preference (Tape & Reel vs. Cut Tape)
• Compliance certifications required by the end application
• Thermal design margin requirements (the 6KPE24CAH provides higher peak pulse power rating)

Both devices are electrically interchangeable at the specified 24V clamping voltage and support identical operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the 6KPE24CAH replace the TLP24CA in existing designs?

A: Yes. Both devices share identical voltage ratings (24V reverse standoff, 38.9V clamping), bidirectional operation, and through-hole axial packaging. The 6KPE24CAH provides higher peak pulse current and power ratings, which are compatible with applications designed for the TLP24CA baseline specifications.

Q: What is the difference in peak pulse current between these parts?

A: The TLP24CA handles 131.1A peak pulse current, while the 6KPE24CAH handles 169.7A. This difference reflects enhanced performance in the substitute part and does not create incompatibility in applications requiring the lower rating.

Q: Are there packaging differences between these parts?

A: Both parts use through-hole axial mounting. The TLP24CA is supplied in Tape & Reel (TR) packaging, while the 6KPE24CAH is supplied in Cut Tape (CT) packaging. The physical component form factor remains identical.

Q: Which part should be selected for automotive applications?

A: The 6KPE24CAH carries AEC-Q101 qualification and automotive-grade designation, making it the appropriate choice for automotive applications. The TLP24CA is suitable for general-purpose applications.

Q: Are both parts RoHS compliant?

A: The TLP24CA is explicitly ROHS3 compliant. RoHS compliance status for the 6KPE24CAH is not specified in the provided data.
