TLP24A Equivalent & Substitute Parts

Part Overview

The TLP24A is a high-reliability unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse, designed for general-purpose transient voltage protection applications. This through-hole axial component operates across a wide temperature range and is ROHS3 compliant. The part is currently active in production with 673 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to availability constraints, design flexibility, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLP24A are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 24V
• Voltage - Breakdown (Min): 26.7V
• Voltage - Clamping (Max) @ Ipp: 38.9V
• Unidirectional channel configuration (1 channel)
• Through-hole axial mounting type
• Operating temperature range: -55°C to 175°C (TJ)

Allowable Variation Parameters:

• Current - Peak Pulse (10/1000µs): May exceed the main part specification
• Power - Peak Pulse: May exceed the main part specification
• Packaging format: Cut Tape (CT) or Tape & Reel (TR) are interchangeable for through-hole components
• Manufacturer: Different manufacturers acceptable if electrical and mechanical specifications align

The 6KPE24AH from Eaton - Electronics Division qualifies as a substitute because it maintains identical voltage specifications (24V standoff, 26.7V breakdown, 38.9V clamping) and unidirectional configuration, while providing higher peak pulse current (169.7A) and power dissipation (6.6kW). Both components share the same through-hole axial package format and identical operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

TLP24A (Littelfuse) is the primary specification. This component is active in production with established supply availability (673 units in stock) and carries ROHS3 compliance certification.

6KPE24AH (Eaton - Electronics Division) is a qualified substitute for applications where the TLP24A is unavailable or where higher transient current handling capability (169.7A versus 131.1A) and power dissipation (6.6kW versus 5kW) provide design margin. The 6KPE24AH carries AEC-Q101 automotive qualification, which exceeds general-purpose requirements. Both components maintain identical voltage protection characteristics and operating temperature specifications, ensuring functional equivalence in circuit protection applications.

Selection between these parts should be based on availability, supply chain requirements, and whether the enhanced current and power ratings of the 6KPE24AH provide beneficial design margin for the application.

Frequently Asked Questions (FAQ)

Q: Can the 6KPE24AH replace the TLP24A in existing designs?

A: Yes. Both components share identical voltage specifications (24V standoff, 26.7V breakdown, 38.9V clamping) and unidirectional configuration. The 6KPE24AH provides higher peak pulse current and power dissipation, which is compatible with circuits designed for the TLP24A. Through-hole axial mounting is identical.

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

A: The TLP24A is rated for 131.1A peak pulse current (10/1000µs), while the 6KPE24AH is rated for 169.7A. The 6KPE24AH provides approximately 29% higher transient current handling capability.

Q: Are the packaging formats interchangeable?

A: Both components use through-hole axial packages. The TLP24A is supplied in Tape & Reel (TR) format, while the 6KPE24AH is supplied in Cut Tape (CT) format. Both formats are compatible with standard through-hole assembly processes.

Q: Do both parts meet the same compliance standards?

A: The TLP24A is ROHS3 compliant. The 6KPE24AH carries AEC-Q101 automotive qualification. Both are REACH unaffected and classified as EAR99 for export control purposes.

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

A: Both the TLP24A and 6KPE24AH operate across -55°C to 175°C (junction temperature), providing identical thermal performance specifications.
