15KP280CA-TP Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 15KP280CA-TP is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This through-hole axial component operates across a temperature range of -55°C to 175°C and is RoHS3 compliant with unlimited moisture sensitivity rating. The part is currently active in production and available in Tape & Reel packaging. Equivalent and substitute parts are identified based on matching electrical characteristics and mechanical compatibility within the 280V reverse standoff voltage class.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 15KP280CA-TP are qualified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Voltage - Reverse Standoff (Typ): 280V
• Type: Zener, Bidirectional
• Mounting Type: Through Hole, Axial configuration
• Power - Peak Pulse: 15000W or higher
• RoHS3 Compliance
• Operating Temperature range compatibility

Substitution Logic: Parts are grouped into two categories based on power rating alignment. The 15KPA280CA and 15KPA280CA-B maintain identical 15kW peak pulse power ratings with matching 280V standoff voltage, making them direct functional equivalents despite minor variations in clamping voltage (454.5V vs 452V) and package designations (P600 vs R-6). The 30KPA280CA represents an upgraded substitute with doubled power capacity (30kW) while maintaining the same 280V standoff voltage, suitable for applications requiring enhanced transient energy absorption.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (15KPA280CA and 15KPA280CA-B): Both parts maintain identical electrical specifications at 15kW peak pulse power and 280V standoff voltage. The 15KPA280CA-B from Littelfuse Inc. supports the full -55°C to 175°C operating temperature range matching the original 15KP280CA-TP. The 15KPA280CA from Good-Ark Semiconductor operates to 150°C maximum junction temperature, which may limit suitability in high-temperature applications. All three parts are RoHS3 compliant and active in production.

Upgraded Substitute (30KPA280CA): The 30KPA280CA provides doubled peak pulse power capacity (30kW) while maintaining the 280V standoff voltage specification. This part is suitable for applications requiring enhanced transient suppression capability. Operating temperature range extends to 175°C, and RoHS3 compliance is confirmed. This substitute is appropriate when circuit protection margins require higher energy absorption capacity.

Packaging Consideration: The original 15KP280CA-TP uses R-6 axial package, while substitute parts employ P600 axial package. Both are through-hole axial configurations with compatible mechanical footprints for standard PCB applications.

Frequently Asked Questions (FAQ)

Q: Can 15KPA280CA and 15KPA280CA-B be used interchangeably with 15KP280CA-TP? A: Yes, both parts are functionally equivalent at the 15kW power level with matching 280V standoff voltage. The 15KPA280CA-B is preferred for applications requiring full -55°C to 175°C temperature operation. The 15KPA280CA is suitable for applications with maximum junction temperatures not exceeding 150°C.

Q: What is the difference between the R-6 and P600 package designations? A: Both are through-hole axial packages. R-6 and P600 refer to different package outline standards but maintain compatible mechanical footprints for standard PCB through-hole mounting. Verify PCB pad spacing against component datasheets for your specific application.

Q: When should the 30KPA280CA be selected instead of the 15KPA280CA? A: The 30KPA280CA provides twice the peak pulse power capacity (30kW vs 15kW) while maintaining the same 280V standoff voltage. Select this part when circuit analysis indicates transient energy levels exceed 15kW or when design margins require enhanced protection capability.

Q: Are all substitute parts RoHS3 compliant? A: Yes, all listed substitute parts including 15KPA280CA, 15KPA280CA-B, and 30KPA280CA are RoHS3 compliant and suitable for applications requiring RoHS compliance.

Q: What is the moisture sensitivity rating for these TVS diodes? A: The 15KP280CA-TP and 30KPA280CA have MSL 1 (Unlimited) rating. The 15KPA280CA-B has MSL Not Applicable. The 15KPA280CA moisture sensitivity level was not specified in available data. Refer to manufacturer datasheets for detailed moisture handling requirements.
