5KP75A-G Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 5KP75A-G is a unidirectional Zener-type transient voltage suppressor manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This through-hole axial component operates across a temperature range of -55°C to 150°C and is RoHS3 compliant. The part is currently active in production with 1044 units in stock. Substitute parts are identified based on matching electrical specifications and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP75A-G is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 75V
• Voltage - Breakdown (Min): 83.3V minimum
• Voltage - Clamping (Max) @ Ipp: 121V nominal range
• Current - Peak Pulse (10/1000µs): minimum 41.32A
• Power - Peak Pulse: 5000W or greater
• Mounting Type: Through Hole
• Type: Zener, Unidirectional
• Category: Transient Voltage Suppressors (TVS)
• Compliance: RoHS3 Compliant

Three substitute parts meet these criteria with matching or superior electrical performance and compatible mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with RoHS3 compliance and REACH status documentation. Selection between 5KP75A (Littelfuse) and 5KP75A-E3/54 (Vishay) is based on electrical equivalence, as both maintain identical voltage and power specifications to the main part with marginally higher peak pulse current ratings. Both offer extended operating temperature ranges to 175°C compared to the 5KP75A-G specification of 150°C.

The 15KPA75A (MDE Semiconductor) provides superior power dissipation capability at 15000W with proportionally higher peak pulse current (123.8A), suitable for applications requiring enhanced transient protection margin. This part maintains voltage specifications within acceptable tolerance and operates across the same temperature range as the Littelfuse and Vishay alternatives.

Package compatibility requires consideration: the 5KP75A-G uses R-6 axial packaging, while all substitute parts employ P600 axial packaging. Both are through-hole axial formats with mechanical compatibility for standard PCB footprints.

Frequently Asked Questions (FAQ)

Q: Can the 5KP75A (Littelfuse) directly replace the 5KP75A-G?

A: Yes. Both parts share identical voltage specifications (75V standoff, 83.3V breakdown, 121V clamping) and 5000W power rating. The Littelfuse variant offers equivalent electrical performance with a higher operating temperature ceiling (175°C vs. 150°C). Package format differs (P600 vs. R-6), but both are standard through-hole axial configurations compatible with typical PCB layouts.

Q: What is the difference between the 5KP75A-E3/54 and the main part?

A: The 5KP75A-E3/54 (Vishay TransZorb series) maintains identical electrical specifications to the 5KP75A-G with peak pulse current of 41.3A versus 41.32A. Operating temperature extends to 175°C. The primary difference is manufacturer and package designation (P600 vs. R-6 axial).

Q: When should the 15KPA75A be selected instead of the 5KP75A variants?

A: The 15KPA75A is selected when applications require higher transient energy absorption capacity. With 15000W peak pulse power and 123.8A peak pulse current, this part provides enhanced protection margin. Voltage specifications remain compatible (75V standoff, 83.8V breakdown, 122V clamping). Selection depends on circuit transient severity requirements, not on voltage compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 5KP75A (Littelfuse), 5KP75A-E3/54 (Vishay), and 15KPA75A (MDE) are all RoHS3 compliant with MSL rating of 1 (Unlimited). All parts carry EAR99 ECCN classification and HTSUS code 8541.10.0080.

Q: What is the impact of package format differences?

A: The 5KP75A-G uses R-6 axial packaging while substitute parts use P600 axial packaging. Both are through-hole axial formats. Physical dimensions may vary slightly, requiring PCB footprint verification. Electrical performance and mounting methodology remain compatible for standard through-hole assembly processes.

Q: Do all parts support the same applications?

A: Yes. All parts are classified for general-purpose transient voltage suppression with no power line protection designation. Electrical compatibility across the 75V voltage class ensures functional equivalence in overvoltage protection circuits.
