15KP20CA-TP Equivalent & Substitute Parts

Part Overview

The 15KP20CA-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 a 20V reverse standoff voltage and provides 15kW peak pulse power dissipation in an R-6 axial through-hole package. The part is currently active and ROHS3 compliant. Substitute parts may be required due to inventory constraints, packaging preferences, or application-specific thermal or electrical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 15KP20CA-TP is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 20V
• Voltage - Breakdown (Min): 22.2V minimum
• Voltage - Clamping (Max) @ Ipp: 34.3V maximum
• Power - Peak Pulse: 15000W (15kW)
• Type: Zener, Bidirectional
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

The substitute parts listed maintain the same voltage protection window (20V standoff, 22.2V breakdown minimum, 34.3V clamping maximum) and 15kW power rating. Differences in packaging format (R-6 vs. P600) and manufacturer do not affect electrical equivalence for general-purpose TVS applications. The 5KP250CA is included in the original substitute list but operates at a different voltage class (250V standoff) and is not electrically equivalent; it is listed for reference only.

Parameter Comparison

Engineering Selection Recommendations

15KPA20CA (Good-Ark Semiconductor): This part is a direct electrical equivalent with identical 20V standoff, 22.34V breakdown, 34.3V clamping, and 15kW power rating. The primary difference is packaging format (P600 vs. R-6) and operating temperature range (-55°C to 150°C vs. -55°C to 175°C). Selection is appropriate where P600 axial packaging is acceptable and maximum junction temperature does not exceed 150°C. ROHS3 compliance and active product status are confirmed.

5KP20CA (Littelfuse): This part maintains the same 20V voltage class and through-hole axial mounting but operates at reduced power dissipation (5kW vs. 15kW) and lower peak pulse current (157.4A vs. 440.2A). The clamping voltage is slightly lower at 32.4V. Selection is appropriate only for applications where peak pulse power does not exceed 5kW. Operating temperature range extends to 175°C. ROHS3 compliance and active product status are confirmed.

5KP250CA (Littelfuse Inc.): This part operates at a different voltage class (250V standoff, 277V breakdown, 425V clamping) and is not electrically equivalent to the 15KP20CA-TP. This part is not suitable as a substitute for 20V protection applications.

Frequently Asked Questions (FAQ)

Q: Can 15KPA20CA replace 15KP20CA-TP in all applications?

A: 15KPA20CA is electrically equivalent for voltage protection (20V standoff, 34.3V clamping, 15kW power). The primary consideration is operating temperature: 15KPA20CA is rated to 150°C junction temperature versus 175°C for the original part. If your application operates below 150°C, substitution is valid. Packaging format differs (P600 vs. R-6 axial), but both are through-hole axial configurations.

Q: Why is 5KP20CA listed as a substitute if it has lower power rating?

A: 5KP20CA maintains the same voltage protection window (20V standoff, 22.2V breakdown, 32.4V clamping) and is electrically compatible for voltage clamping function. However, it is rated for only 5kW peak pulse power versus 15kW for the original part. Substitution is valid only if your application's peak pulse power requirement does not exceed 5kW.

Q: Is 5KP250CA compatible with 15KP20CA-TP?

A: No. 5KP250CA operates at 250V standoff voltage and is designed for high-voltage protection applications. It is not electrically equivalent to the 20V protection class of 15KP20CA-TP and cannot be used as a substitute.

Q: What are the packaging differences between R-6 and P600?

A: Both R-6 and P600 are through-hole axial package formats for TVS diodes. R-6 is the package used by the original 15KP20CA-TP. P600 is used by the substitute parts 15KPA20CA and 5KP20CA. Both are compatible with standard through-hole PCB assembly processes; the primary difference is physical dimensions and lead spacing.

Q: Are all listed parts ROHS3 compliant?

A: Yes. The main part 15KP20CA-TP and all substitute parts (15KPA20CA, 5KP20CA, 5KP250CA) are ROHS3 compliant and carry active product status.
