Key Parameters

Substitute Part Grouping Explanation

Substitution of the 30KPA280C is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 280V
• Voltage - Clamping (Max) @ Ipp: Must remain within acceptable system tolerance
• Current - Peak Pulse (10/1000µs): 65.3A minimum
• Power - Peak Pulse: 30000W (30kW) minimum
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Type: Zener
• Bidirectional Channels: 1

The 30KPA280CA meets all substitution criteria and is listed as the direct equivalent by the original manufacturer specification.

Parameter Comparison

Engineering Selection Recommendations

The 30KPA280CA is the qualified substitute for the 30KPA280C. Both components maintain identical reverse standoff voltage, peak pulse current, and peak pulse power ratings. The 30KPA280CA exhibits a lower maximum clamping voltage (464V versus 487.2V), which provides improved transient suppression performance within the same electrical class.

The 30KPA280CA carries Active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The original 30KPA280C is Obsolete and should be replaced with the 30KPA280CA for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA280CA directly replace the 30KPA280C in existing designs?

A: Yes. Both components share identical reverse standoff voltage (280V), peak pulse current (65.3A), peak pulse power (30kW), operating temperature range (-55°C to 175°C), and P600 axial through-hole package. The 30KPA280CA is the manufacturer-specified equivalent.

Q: What is the difference in clamping voltage between these parts?

A: The 30KPA280C has a maximum clamping voltage of 487.2V, while the 30KPA280CA is rated at 464V. The lower clamping voltage of the 30KPA280CA represents improved transient suppression performance and does not compromise circuit protection.

Q: Are both parts RoHS compliant?

A: Yes. Both the 30KPA280C and 30KPA280CA are ROHS3 compliant.

Q: Why is the 30KPA280C listed as Obsolete?

A: The 30KPA280C has reached end-of-life status. The 30KPA280CA is the active replacement and should be used for all new applications and ongoing production requirements.

Q: Is the P600 axial package identical between both parts?

A: Yes. Both components use the P600 axial through-hole package, ensuring mechanical and electrical compatibility in existing PCB layouts.
