5KP85CA-TP Equivalent & Substitute Parts

Part Overview

The 5KP85CA-TP is a transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This bidirectional Zener diode operates with an 85V reverse standoff voltage and provides 137V maximum clamping voltage at peak pulse current, with a peak pulse power rating of 5000W. The device is mounted through-hole in an R-6 axial package and maintains active product status with full ROHS3 compliance.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified voltage and power parameters while maintaining compatibility with through-hole mounting requirements and operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP85CA-TP is determined by the following critical parameters:

• Voltage Rating Match: Reverse standoff voltage of 85V ±tolerance, breakdown voltage minimum of 94.4V or higher, and clamping voltage at or below 137V
• Power Dissipation: Peak pulse power rating of 5000W or greater
• Mounting Configuration: Through-hole axial package format
• Thermal Performance: Operating temperature range encompassing -55°C to 175°C
• Device Type: Bidirectional Zener diode with single channel configuration
• Compliance Status: Active product status with ROHS3 compliance

Two substitute parts meet these criteria: the 15KPA85CA (MDE Semiconductor Inc) and the 5KP85CA (Diotec Semiconductor). Both maintain identical voltage specifications and through-hole mounting while offering equivalent or superior electrical performance.

Parameter Comparison

Engineering Selection Recommendations

15KPA85CA (MDE Semiconductor Inc): This substitute provides superior power dissipation capability at 15000W, triple the main part rating, while maintaining identical voltage specifications. The higher peak pulse current of 109.7A offers enhanced transient protection margin. Both parts share identical operating temperature range and ROHS3 compliance. Package format differs (P600 vs R-6), requiring mechanical verification for board layout compatibility.

5KP85CA (Diotec Semiconductor): This substitute matches the main part's 5000W power rating and 137V clamping voltage exactly. Voltage specifications remain equivalent. Operating temperature range extends to -50°C minimum (versus -55°C for the main part), which is acceptable for most applications. Package format differs (P600 vs R-6), requiring mechanical verification. REACH compliance information is available upon request from the manufacturer.

Both substitutes maintain active product status and full ROHS3 compliance, ensuring regulatory alignment with the original 5KP85CA-TP specification.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA85CA replace the 5KP85CA-TP in all applications?

A: The 15KPA85CA meets all electrical substitution criteria with superior power handling (15000W vs 5000W). However, the package format differs (P600 axial vs R-6 axial), requiring verification that board layout and mechanical constraints accommodate the different package dimensions.

Q: What is the primary difference between the two substitute options?

A: The 15KPA85CA provides 15000W peak pulse power versus 5000W for both the main part and the 5KP85CA substitute. The 5KP85CA substitute offers identical power rating to the main part. Both maintain equivalent voltage specifications. Package format (P600) differs from the main part (R-6) in both cases.

Q: Are there temperature range limitations with the Diotec 5KP85CA substitute?

A: The Diotec 5KP85CA operates from -50°C to 175°C, compared to -55°C to 175°C for the main part. The 5°C difference at the lower temperature limit is acceptable for applications not requiring operation below -50°C.

Q: Do all parts share the same compliance certifications?

A: All three parts (main and both substitutes) are ROHS3 compliant. The 15KPA85CA and Diotec 5KP85CA have REACH compliance information available upon request from their respective manufacturers. The main part is REACH unaffected.

Q: What determines whether a TVS diode can substitute for the 5KP85CA-TP?

A: Substitution requires matching reverse standoff voltage (85V), breakdown voltage (94.4V minimum), clamping voltage (137V maximum), power rating (5000W minimum), through-hole mounting configuration, and operating temperature range compatibility. All three parts meet these criteria.
