Key Parameters

Substitute Part Grouping Explanation

Substitution of the 30KPA60C is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 60V
• Voltage - Clamping (Max) @ Ipp: 102V–107.1V range
• Current - Peak Pulse (10/1000µs): 297.1A or equivalent
• Power - Peak Pulse: 30000W (30kW)
• Operating Temperature: -55°C ~ 175°C (TJ)
• Mounting Type: Through Hole
• Type: Zener, Bidirectional

The substitute parts listed maintain these core electrical specifications within acceptable tolerances. Package variations (P600 vs. R-6) represent mechanical alternatives suitable for the same circuit applications.

Parameter Comparison

Engineering Selection Recommendations

30KPA60CA (MDE Semiconductor Inc): This part is the closest electrical equivalent to the 30KPA60C, maintaining identical reverse standoff voltage (60V), peak pulse current (297.1A), and power dissipation (30kW). The clamping voltage is 102V versus 107.1V on the original, representing a 5.1V reduction. This part is active in production and ROHS3 compliant. The P600 package matches the original form factor.

30KP60CA-TP (Micro Commercial Co): This part maintains the 60V reverse standoff voltage and 30kW power rating. The clamping voltage is 102V. The R-6 package differs from the original P600, requiring mechanical board layout adjustment. This part is active in production and ROHS3 compliant.

15KP60CA-TP (Micro Commercial Co): This part maintains the 60V reverse standoff voltage and operating temperature range. The power dissipation is 15kW, representing a 50% reduction from the original 30kW specification. The clamping voltage is 97.3V. The R-6 package differs from the original P600. This part is active in production and ROHS3 compliant. Selection of this part requires confirmation that the reduced power rating is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can 30KPA60CA directly replace 30KPA60C without circuit modification?

A: Yes. The 30KPA60CA maintains identical electrical specifications for reverse standoff voltage (60V), peak pulse current (297.1A), and power dissipation (30kW). The clamping voltage difference of 5.1V (102V vs. 107.1V) falls within normal component tolerance ranges. The P600 package is mechanically identical.

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

A: Both are through-hole axial packages formats for TVS diodes. P600 and R-6 represent different physical dimensions and lead configurations. Circuit functionality is identical; however, board layout and component placement must be adjusted to accommodate the different package geometry.

Q: Why is 15KP60CA-TP listed as a substitute if the power rating is lower?

A: The 15KP60CA-TP is listed based on matching the core voltage protection parameters (60V reverse standoff, 97.3V clamping). The 15kW power rating is 50% lower than the original 30kW specification. This part is suitable only for applications where peak pulse power requirements do not exceed 15kW.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (30KPA60CA, 15KP60CA-TP, 30KP60CA-TP) are ROHS3 compliant, matching the compliance status of the original 30KPA60C.

Q: What is the significance of "Active" product status for substitute parts?

A: Active product status indicates the part is currently in production and available for procurement. The original 30KPA60C is obsolete, meaning it is no longer manufactured. All substitute parts listed are active, ensuring long-term availability and supply chain continuity.
