5KP36CA-TP Equivalent & Substitute Parts

Part Overview

The 5KP36CA-TP is a bidirectional transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This through-hole component features a 36V reverse standoff voltage with a 58.1V maximum clamping voltage and 5000W peak pulse power rating. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent voltage protection characteristics, power ratings, and through-hole mounting compatibility are maintained within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP36CA-TP are classified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Voltage - Reverse Standoff: 36V nominal
• Voltage - Breakdown (Min): 40V or greater
• Bidirectional operation: 1 channel
• Mounting: Through-hole axial configuration
• Type: Zener TVS diode
• Applications: General Purpose

Substitution Categories:

Direct Equivalent (5KP36CA): Maintains identical voltage ratings (36V standoff, 40V breakdown, 58.1V clamping) and 5000W power rating. Different manufacturer (Diotec Semiconductor) with P600 package variant. Operating temperature range -50°C to 175°C.

Higher Power Rating Substitutes: Parts with 36V standoff voltage but increased power dissipation capacity (15KPA36CA at 15kW, 30KPA36CA at 30kW). These provide enhanced transient protection margin while maintaining voltage compatibility.

Lower Power Rating Substitute (1.5KE36CA): Operates at reduced power rating (1500W) with modified voltage characteristics (30.8V standoff, 34.2V breakdown, 49.9V clamping). Suitable only for applications with lower energy transients.

Parameter Comparison

Engineering Selection Recommendations

5KP36CA (Diotec Semiconductor): Direct functional equivalent with identical voltage and power specifications. ROHS3 compliant. Suitable for one-to-one replacement where R-6 to P600 package transition is acceptable. Minimum operating temperature -50°C versus -55°C on original part.

15KPA36CA (MDE Semiconductor Inc): Maintains 36V voltage class with 15kW power rating. ROHS3 compliant. Appropriate for applications requiring enhanced transient energy absorption while preserving voltage protection thresholds. Bulk packaging requires verification of procurement requirements.

30KPA36CA (Good-Ark Semiconductor): Highest power rating option at 30kW with 36V voltage class. ROHS3 compliant. Maximum operating temperature 150°C (10°C reduction from main part). Suitable for high-energy transient environments where voltage compatibility is maintained.

1.5KE36CA (Good-Ark Semiconductor): Lower power rating (1500W) with reduced voltage standoff (30.8V) and breakdown (34.2V). ROHS3 compliant. Selection restricted to applications with lower transient energy and voltage tolerance for reduced protection thresholds.

Frequently Asked Questions (FAQ)

Q: Can 5KP36CA from Diotec Semiconductor directly replace 5KP36CA-TP from Micro Commercial Co?

A: Yes. Both parts maintain identical voltage ratings (36V standoff, 40V breakdown, 58.1V clamping) and 5000W power dissipation. Package designation differs (P600 versus R-6), but both are through-hole axial configurations. Verify PCB footprint compatibility before substitution.

Q: What is the primary difference between the 5KP36CA and higher-power alternatives like 15KPA36CA or 30KPA36CA?

A: The 36V voltage protection class remains constant across all three parts. The 15KPA36CA provides 15kW peak pulse power (3× the 5KP36CA), and the 30KPA36CA provides 30kW (6× the 5KP36CA). Selection depends on transient energy levels in the application. Higher power ratings provide greater margin for energy absorption without exceeding clamping voltage limits.

Q: Is the 1.5KE36CA suitable as a substitute for the 5KP36CA-TP?

A: The 1.5KE36CA operates in a different voltage class (30.8V standoff versus 36V) with significantly lower power rating (1500W versus 5000W). Substitution is valid only for applications with lower transient energy and where the reduced voltage standoff does not compromise circuit protection requirements.

Q: What packaging considerations apply when substituting between these TVS diodes?

A: The 5KP36CA-TP uses R-6 axial package, while direct equivalent 5KP36CA uses P600 axial package. Both are through-hole configurations with similar physical dimensions. The 1.5KE36CA uses DO-201AE package, which may require PCB layout modification. Verify lead spacing and hole diameter compatibility with existing PCB design before component selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, consistent with the original 5KP36CA-TP specification.

Q: What is the operating temperature impact when selecting 30KPA36CA as a substitute?

A: The 30KPA36CA maximum operating temperature is 150°C, compared to 175°C for the 5KP36CA-TP. This 25°C reduction should be evaluated against application thermal requirements. For circuits operating near upper temperature limits, the 15KPA36CA or 5KP36CA alternatives maintain the full 175°C rating.
