Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4KE110CA-G is determined by the following critical parameters:

• Voltage - Reverse Standoff: 94V (primary protection threshold)
• Voltage - Clamping (Max) @ Ipp: 152V (maximum transient suppression level)
• Current - Peak Pulse: minimum 2.63A (surge handling capacity)
• Power - Peak Pulse: 400W (energy dissipation capability)
• Mounting Type: Through Hole (mechanical compatibility)
• Package / Case: DO-204AL or DO-41 (physical form factor)
• Operating Temperature: -55°C minimum and 150°C minimum upper limit
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The P4KE110CA from Taiwan Semiconductor Corporation qualifies as a direct equivalent based on matching all critical electrical parameters and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The P4KE110CA from Taiwan Semiconductor Corporation is a qualified equivalent to the P4KE110CA-G. Both components maintain identical electrical protection characteristics with matching voltage ratings, clamping specifications, and power dissipation capabilities. Both devices carry ROHS3 compliance certification and are rated for the same operating temperature minimum of -55°C.

The Taiwan Semiconductor variant offers a higher maximum junction temperature rating of 175°C compared to 150°C, providing additional thermal margin in applications with elevated ambient conditions. The peak pulse current specification of 2.7A exceeds the 2.63A requirement, ensuring adequate surge handling capacity.

The primary distinction between these parts is packaging format: the Comchip P4KE110CA-G is supplied in bulk packaging, while the Taiwan Semiconductor P4KE110CA is supplied in tape and reel format. This difference affects assembly line integration and component handling but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the P4KE110CA (Taiwan Semiconductor) directly replace the P4KE110CA-G (Comchip) in existing designs?

A: Yes. Both components share identical voltage protection parameters (94V standoff, 152V clamping), current ratings, power dissipation, and compliance certifications. The Taiwan Semiconductor variant is electrically and functionally equivalent for all circuit applications.

Q: What is the significance of the different operating temperature ranges?

A: The P4KE110CA-G operates to 150°C junction temperature, while the P4KE110CA operates to 175°C.
