TP5KP15A Equivalent & Substitute Parts

Part Overview

The TP5KP15A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for transient overvoltage protection in electronic circuits. This through-hole axial component operates with a 15V reverse standoff voltage and provides 5kW peak pulse power dissipation. The part is actively produced, AEC-Q101 qualified for automotive applications, and RoHS3 compliant. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility is required while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TP5KP15A is determined by strict electrical and mechanical compatibility criteria. The following parameters must remain constant or within acceptable tolerances for a part to function as a direct substitute:

• Voltage - Reverse Standoff (Typ): 15V
• Voltage - Breakdown (Min): 16.7V
• Voltage - Clamping (Max) @ Ipp: 24.4V
• Unidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: Axial configuration
• Type: Zener diode
• Grade: Automotive
• Qualification: AEC-Q101

The 6KPE15AH from Eaton - Electronics Division meets all critical electrical parameters and maintains automotive-grade qualification with AEC-Q101 certification. While the peak pulse current (270.5A) and power dissipation (6.6kW) exceed the TP5KP15A specifications, these represent enhanced performance characteristics that do not compromise compatibility in applications designed for the TP5KP15A.

Parameter Comparison

Engineering Selection Recommendations

Both the TP5KP15A and 6KPE15AH are active production components with automotive-grade qualification and AEC-Q101 certification, ensuring compliance with automotive industry standards. The 6KPE15AH is suitable as a substitute when the TP5KP15A is unavailable, as it maintains identical voltage specifications (15V reverse standoff, 16.7V breakdown minimum, 24.4V clamping maximum) and unidirectional channel configuration. The 6KPE15AH provides enhanced current handling (270.5A versus 209A) and power dissipation (6.6kW versus 5kW), along with an extended operating temperature range (-55°C to 175°C versus -55°C to 150°C). Both components are RoHS3 compliant with MSL 1 rating and maintain identical through-hole axial mounting compatibility. Selection between these parts should be based on component availability and application-specific thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can the 6KPE15AH directly replace the TP5KP15A in existing designs?

A: Yes. Both components share identical voltage specifications (15V reverse standoff, 16.7V breakdown, 24.4V clamping) and unidirectional channel configuration. The through-hole axial package format ensures mechanical compatibility. The 6KPE15AH's enhanced current and power ratings do not create compatibility issues in applications designed for the TP5KP15A.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution is determined by matching reverse standoff voltage (15V), breakdown voltage minimum (16.7V), clamping voltage maximum (24.4V), channel configuration (unidirectional), and package type (through-hole axial). These parameters ensure the substitute part functions identically in transient overvoltage protection applications.

Q: Are both parts automotive-qualified?

A: Yes. Both the TP5KP15A and 6KPE15AH carry automotive-grade designation with AEC-Q101 qualification, meeting automotive industry reliability and quality standards.

Q: What is the difference in operating temperature ranges?

A: The TP5KP15A operates from -55°C to 150°C (TJ), while the 6KPE15AH operates from -55°C to 175°C (TJ). The 6KPE15AH provides a 25°C higher maximum junction temperature, offering enhanced thermal performance in high-temperature applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both components are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, meeting environmental and regulatory requirements for electronic component manufacturing and assembly.
