P6KE11A-HF Equivalent & Substitute Parts

Part Overview

The P6KE11A-HF is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This through-hole component operates with a reverse standoff voltage of 9.4V and provides clamping at 15.6V maximum, making it suitable for protecting sensitive circuits from transient voltage spikes. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6KE11A-HF is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 9.4V
• Voltage - Clamping (Max) @ Ipp: 15.6V
• Current - Peak Pulse (10/1000µs): minimum 38A
• Power - Peak Pulse: 600W
• Mounting Type: Through Hole
• Package / Case: DO-15 (DO-204AC, Axial)
• Type: Zener (Unidirectional)
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant

The P6KE11A manufactured by Taiwan Semiconductor Corporation meets all substitution criteria within the allowed parameter tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

The P6KE11A manufactured by Taiwan Semiconductor Corporation is a direct substitute for the P6KE11A-HF. Both components maintain identical electrical specifications for reverse standoff voltage, clamping voltage, and power dissipation. The Taiwan Semiconductor variant demonstrates peak pulse current of 38A, which remains within the operational tolerance of the original specification at 38.46A. Both parts carry active product status and full ROHS3 compliance certification.

The primary distinction between the two parts is packaging format: the original uses Tape & Box (TB) configuration, while the substitute is supplied in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not impact electrical performance or mechanical fit in through-hole applications.

Component selection should be based on packaging availability, procurement lead times, and assembly line compatibility with either TB or TR formats.

Frequently Asked Questions (FAQ)

Q: Can the P6KE11A (Taiwan Semiconductor) be used as a direct replacement for P6KE11A-HF in existing designs?

A: Yes. Both components share identical electrical specifications for voltage clamping, reverse standoff voltage, and power dissipation. The through-hole DO-15 package is mechanically identical, allowing direct PCB substitution without design modification.

Q: What is the difference between Tape & Box (TB) and Tape & Reel (TR) packaging?

A: TB packaging supplies components in tape format within a protective box, typically for smaller order quantities. TR packaging supplies components on continuous reels, optimized for high-volume automated assembly. Both formats contain the same component; the difference is in handling and assembly compatibility.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both the P6KE11A-HF and P6KE11A maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity ratings (MSL 1 - Unlimited). Regulatory and environmental compliance is equivalent.

Q: What is the significance of the 0.46A difference in peak pulse current specification?

A: The P6KE11A-HF specifies 38.46A while the P6KE11A specifies 38A. This 1.2% variance falls within standard manufacturing tolerances for TVS diodes and does not affect circuit protection performance in general-purpose applications.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Both parts are rated for identical operating temperature ranges (-55°C to 150°C) and carry active product status. Interchangeability depends on application-specific reliability requirements and qualification procedures established by the end user.
