Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4KE100A-TP are classified based on electrical parameter compatibility within the TVS diode category. The primary substitution criteria are:

Direct Substitute (P4KE100A by Taiwan Semiconductor Corporation): Maintains identical electrical specifications across all critical parameters: 85.5V reverse standoff voltage, 95V minimum breakdown voltage, 137V maximum clamping voltage, and 3A peak pulse current. Package designation differs between DO-41 and DO-204AL, which are mechanically equivalent axial through-hole formats. This part qualifies as a direct functional replacement.

Similar Substitute (P6KE100A by Fairchild Semiconductor): Differs in reverse standoff voltage (100V vs. 85.5V) and peak pulse current (4.4A vs. 3A), resulting in higher power dissipation (600W vs. 400W). Clamping voltage remains at 137V. Operating temperature range is reduced to -55°C to 150°C. This part provides enhanced transient suppression capability but operates at different voltage thresholds and requires thermal design verification for the higher power rating.

Parameter Comparison

Engineering Selection Recommendations

P4KE100A (Taiwan Semiconductor Corporation): Select this direct substitute when component availability from the primary manufacturer is constrained. Electrical and thermal characteristics are identical to the P4KE100A-TP. Both parts maintain ROHS3 compliance and active production status. Mechanical compatibility is confirmed through equivalent axial through-hole packaging (DO-41/DO-204AL).

P6KE100A (Fairchild Semiconductor): Select this similar substitute only when circuit design permits operation at 100V reverse standoff voltage and higher peak pulse current (4.4A). The reduced maximum operating temperature (150°C vs. 175°C) must be evaluated against application thermal requirements. This part is suitable for applications requiring enhanced transient suppression capability with higher energy dissipation margins.

Frequently Asked Questions (FAQ)

Q: Can P4KE100A replace P4KE100A-TP directly? A: Yes. The P4KE100A by Taiwan Semiconductor Corporation is a direct substitute. Electrical specifications are identical, and both use equivalent axial through-hole packaging formats (DO-41 and DO-204AL). No circuit redesign is required.

Q: What are the key differences between P4KE100A-TP and P6KE100A? A: The P6KE100A operates at a higher reverse standoff voltage (100V vs. 85.5V) and supports higher peak pulse current (4.4A vs. 3A), resulting in 600W peak power versus 400W. The maximum operating temperature is reduced from 175°C to 150°C. These differences affect circuit protection thresholds and thermal design.

Q: Are DO-41 and DO-204AL packages mechanically interchangeable? A: Yes. Both designations refer to equivalent axial through-hole package formats suitable for PCB mounting. DO-41 and DO-204AL are mechanically and electrically compatible in through-hole applications.

Q: Can P6KE100A be used in applications designed for P4KE100A-TP? A: Substitution is possible only if the circuit design accommodates the higher reverse standoff voltage (100V) and the reduced maximum operating temperature (150°C). The higher peak pulse current provides additional transient suppression margin but changes the voltage protection threshold.

Q: What compliance certifications apply to these parts? A: P4KE100A-TP and P4KE100A are both ROHS3 compliant. RoHS compliance status for P6KE100A is not specified in available documentation.
