Engineering Selection Recommendations
The P6KE110A is the primary substitute for the obsolete P6KE110. Both components share identical reverse standoff voltage (94V), peak pulse power rating (600W), and physical package configuration (DO-15 through-hole axial). The P6KE110A maintains full ROHS3 compliance and EAR99 export classification, ensuring regulatory continuity.
The P6KE110A offers the additional advantage of active product status with confirmed inventory availability (16,240 pcs), eliminating supply chain risk associated with obsolete components. The clamping voltage differential (152V vs. 159.6V) and specified peak pulse current (4A) represent minor parameter variations within acceptable tolerance for general-purpose transient suppression applications.
Selection of the P6KE110A is supported by identical electrical classification, mechanical compatibility, and regulatory compliance status.
Frequently Asked Questions (FAQ)
Q: Can the P6KE110A directly replace the P6KE110 in existing designs?
A: Yes. Both components are unidirectional Zener TVS diodes with identical reverse standoff voltage (94V), peak pulse power rating (600W), and DO-15 through-hole axial package configuration. No PCB layout modifications are required.
Q: What is the significance of the clamping voltage difference (159.6V vs. 152V)?
A: The P6KE110A exhibits lower clamping voltage (152V), providing marginally improved transient suppression performance. This represents a favorable parameter variation for overvoltage protection circuits.
Q: Why is the P6KE110 classified as obsolete?
A: Obsolete status indicates the component is no longer manufactured by Littelfuse Inc. The P6KE110A from Taiwan Semiconductor Corporation provides functional equivalence with active manufacturing status and sustained inventory availability.
Q: Are there packaging options for the P6KE110A?
A: The P6KE110A is available in Tape & Reel (TR) packaging for automated assembly processes. The base component maintains DO-15 through-hole axial package configuration.
Q: Do both components meet current regulatory requirements?
A: Yes. Both the P6KE110 and P6KE110A are ROHS3 compliant and classified under EAR99 export control, with identical HTSUS commodity code 8541.10.0080.
Q: What is the operating temperature range for the P6KE110A?
A: Operating temperature range for the P6KE110A is not specified in the provided technical data. The P6KE110 operates across -55°C to 175°C (TJ).
