30KP280CA-TP Equivalent & Substitute Parts

Part Overview

The 30KP280CA-TP is a bidirectional 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. The part is currently active in production with 986 units in stock. Substitute parts are identified based on matching electrical characteristics including reverse standoff voltage, breakdown voltage, clamping voltage, and power dissipation ratings, while accommodating variations in packaging and peak pulse current specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 30KP280CA-TP is determined by the following critical electrical parameters:

• Voltage - Reverse Standoff (Typ): 280V
• Voltage - Breakdown (Min): 312.8V
• Voltage - Clamping (Max) @ Ipp: 464V (±tolerance)
• Power - Peak Pulse: 30000W (30kW)
• Type: Zener, Bidirectional
• Mounting Type: Through Hole, Axial

The identified substitute parts maintain these core electrical specifications. Variations in packaging format (Tape & Reel, Cut Tape, or Bulk), package case designation (R-6 vs P600), and peak pulse current ratings do not affect functional equivalence when the voltage and power parameters remain within specification. All substitute parts are active products with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity.

30KPA280CA (MDE Semiconductor Inc) provides the closest electrical match to the 30KP280CA-TP, with identical reverse standoff voltage (280V), breakdown voltage (312.8V), clamping voltage (464V), and peak pulse power (30kW). This part accommodates the full operating temperature range (-55°C to 175°C) and is available in bulk packaging. The P600 package case differs from the R-6 designation but maintains through-hole axial mounting compatibility.

15KPA280CA-B (Littelfuse Inc.) and 15KPA280CA (Good-Ark Semiconductor) are half-power alternatives, rated at 15kW peak pulse power. These parts maintain the same voltage specifications (280V standoff, 312.8V breakdown, 454.5V clamping) and through-hole axial mounting. The 15KPA280CA-B supports the full temperature range (-55°C to 175°C), while the 15KPA280CA operates to 150°C maximum junction temperature. Selection of these lower-power alternatives is appropriate only when circuit requirements do not exceed 15kW peak pulse dissipation.

Frequently Asked Questions (FAQ)

Q: Can 15KPA280CA parts substitute for 30KP280CA-TP in all applications?

A: No. The 15KPA280CA series is rated for 15kW peak pulse power, while the 30KP280CA-TP is rated for 30kW. Substitution is valid only when the circuit's peak pulse power requirement does not exceed 15kW. Voltage specifications (280V standoff, 312.8V breakdown) are identical across all parts.

Q: What is the difference between R-6 and P600 package cases?

A: Both are through-hole axial packages for TVS diodes. The R-6 and P600 designations refer to different physical case geometries. Mechanical compatibility with PCB footprints must be verified during design integration, as lead spacing and body dimensions may differ.

Q: Are packaging formats (Tape & Reel, Cut Tape, Bulk) interchangeable?

A: Packaging format affects supply chain logistics and handling but does not alter component electrical performance. Tape & Reel, Cut Tape, and Bulk formats contain identical components; selection depends on assembly process requirements and order quantities.

Q: Does the operating temperature difference between 150°C and 175°C affect substitution?

A: The 15KPA280CA (Good-Ark) operates to 150°C maximum junction temperature, while the 30KP280CA-TP, 15KPA280CA-B, and 30KPA280CA operate to 175°C. If the application requires sustained operation above 150°C, the 15KPA280CA is not suitable. The 15KPA280CA-B and 30KPA280CA accommodate the full temperature range.

Q: What compliance certifications apply to all substitute parts?

A: All parts listed are ROHS3 compliant and REACH unaffected, with ECCN classification EAR99 and HTSUS code 8541.10.0080. Moisture Sensitivity Level is 1 (Unlimited) for all parts except 15KPA280CA-B, which lists MSL as Not Applicable.
