15KP110CA-TP Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 15KP110CA-TP is an active Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This bidirectional Zener diode operates with a reverse standoff voltage of 110V and provides peak pulse power dissipation of 15kW. The component is housed in an R-6 axial package for through-hole mounting and maintains ROHS3 compliance with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching critical electrical parameters: reverse standoff voltage, clamping voltage, peak pulse power rating, and compatible through-hole axial packaging. Substitutes must maintain functional equivalence within the specified operating temperature range of -55°C to 175°C.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 15KP110CA-TP are qualified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Reverse Standoff Voltage: 110V (±tolerance)
• Voltage - Breakdown (Min): 122V or higher
• Voltage - Clamping (Max) @ Ipp: 177V–178.6V range
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Package Type: Axial configuration
• Operating Temperature Range: -55°C to 175°C minimum
• RoHS Compliance: ROHS3 Compliant

Secondary Consideration:

• Power - Peak Pulse: 5kW minimum (15kW preferred for full equivalence)

The 15KPA110CA and 5KP110CA meet the primary electrical and mechanical criteria for substitution. The 15KPA110CA provides identical 15kW peak pulse power, while the 5KP110CA operates at reduced 5kW peak pulse power but maintains all voltage specifications and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

15KPA110CA (MDE Semiconductor Inc): This substitute provides full electrical and thermal equivalence to the 15KP110CA-TP. Both components deliver 15kW peak pulse power with matching reverse standoff voltage (110V) and clamping voltage specifications (178V vs. 178.6V). The 15KPA110CA maintains ROHS3 compliance and the same operating temperature range. The primary difference is packaging format (P600 vs. R-6 axial), which may require mechanical verification for board layout compatibility. This substitute is suitable for direct functional replacement in applications requiring full 15kW power dissipation.

5KP110CA (Littelfuse Inc.): This substitute maintains electrical voltage specifications identical to the main part (110V reverse standoff, 177V clamping) and operates within the same temperature range with ROHS3 compliance. However, the 5KP110CA is rated for 5kW peak pulse power, representing a 67% reduction in power dissipation capacity compared to the 15KP110CA-TP. This substitute is applicable only in applications where peak pulse power requirements do not exceed 5kW. Packaging format (P600 axial) requires mechanical verification for board compatibility.

Both substitutes are active products with established supply availability and full regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA110CA replace the 15KP110CA-TP in all applications?

A: The 15KPA110CA provides electrical equivalence across all critical parameters: 110V reverse standoff voltage, 178.6V clamping voltage, and 15kW peak pulse power. Substitution is valid from an electrical standpoint. However, the package format differs (P600 vs. R-6 axial), requiring verification that the physical dimensions and lead spacing are compatible with your PCB layout and assembly process.

Q: What is the key limitation of the 5KP110CA as a substitute?

A: The 5KP110CA maintains all voltage specifications (110V standoff, 177V clamping) and thermal operating range but is rated for 5kW peak pulse power versus the 15kW rating of the main part. This substitute is only appropriate for applications where transient energy levels do not exceed 5kW. If your circuit experiences higher energy transients, the 5KP110CA may not provide adequate protection.

Q: Are there package compatibility concerns with these substitutes?

A: Yes. The main part uses R-6 axial packaging, while both substitutes use P600 axial packaging. Although both are axial through-hole formats, the physical dimensions and lead spacing may differ. Verify that the P600 package dimensions fit your PCB hole spacing and component placement requirements before implementation.

Q: Do all three parts meet the same compliance standards?

A: All three parts are ROHS3 compliant and rated for the same operating temperature range (-55°C to 175°C). The 15KP110CA-TP and 5KP110CA have REACH Unaffected status, while the 15KPA110CA lists REACH info available upon request. All three carry EAR99 ECCN classification and the same HTSUS code (8541.10.0080).

Q: What is the difference between reverse standoff voltage and clamping voltage?

A: Reverse standoff voltage (110V) is the maximum voltage the diode can withstand without conducting. Clamping voltage (177–178.6V) is the voltage at which the diode clamps during a transient event at peak pulse current. The clamping voltage determines the peak voltage protection level delivered to downstream circuitry.

Q: Can I use the 5KP110CA if my application occasionally exceeds 5kW?

A: No. Using a component rated below the actual peak pulse power requirements may result in component failure or inadequate transient suppression. Select a substitute with power rating equal to or greater than your application's maximum transient energy level.
