P6KE11 Equivalent & Substitute Parts

Part Overview

The P6KE11 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection in through-hole applications. This component operates with a reverse standoff voltage of 9.4V and provides 600W peak pulse power dissipation in a DO-15 axial package. The P6KE11 is classified as obsolete, making identification of functionally equivalent active alternatives essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6KE11 is determined by strict equivalence across the following electrical and mechanical parameters:

• Reverse standoff voltage: 9.4V (Typ)
• Breakdown voltage minimum: within acceptable tolerance of 9.95V
• Clamping voltage maximum: within acceptable tolerance of 16.38V @ Ipp
• Peak pulse power rating: 600W minimum
• Package type: DO-15 axial through-hole configuration
• Unidirectional channel configuration: single channel
• RoHS3 compliance status

The P6KE11A from Taiwan Semiconductor Corporation meets all substitution criteria as an active product with identical electrical specifications and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

The P6KE11A is the direct functional equivalent for P6KE11 applications. Both components share identical reverse standoff voltage, peak pulse power rating, and package configuration. The P6KE11A offers the advantage of active product status with confirmed availability and ROHS3 compliance certification. The clamping voltage of the P6KE11A (15.6V maximum) is lower than the P6KE11 (16.38V maximum), providing improved transient suppression performance. Both components are rated for identical operating temperature ranges and moisture sensitivity levels.

Frequently Asked Questions (FAQ)

Q: Can P6KE11A directly replace P6KE11 in existing designs?

A: Yes. Both components share identical reverse standoff voltage (9.4V), peak pulse power rating (600W), and DO-15 axial through-hole package configuration. The P6KE11A provides equivalent or superior electrical performance with active product status.

Q: What is the significance of the clamping voltage difference between P6KE11 and P6KE11A?

A: The P6KE11A exhibits a lower maximum clamping voltage (15.6V vs. 16.38V). This represents improved transient suppression capability, as the component clamps overvoltage transients to a lower peak level, providing enhanced circuit protection.

Q: Are there packaging differences between P6KE11 and P6KE11A?

A: Both components use identical DO-15 axial through-hole packaging. The P6KE11A is supplied in Tape & Reel (TR) format, while the P6KE11 original packaging is not specified. Both are mechanically and electrically compatible in through-hole PCB applications.

Q: What compliance certifications apply to P6KE11A?

A: The P6KE11A is ROHS3 compliant and REACH unaffected. Both certifications match the original P6KE11 specifications, ensuring regulatory compatibility in regulated applications.

Q: Why is P6KE11 listed as obsolete?

A: Obsolete status indicates the component is no longer manufactured by Littelfuse Inc. The P6KE11A from Taiwan Semiconductor Corporation provides active production continuity with equivalent electrical and mechanical specifications.
