P6KE160C Equivalent & Substitute Parts

Part Overview

The P6KE160C is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 136V reverse standoff voltage and 600W peak pulse power rating in a through-hole DO-15 package. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6KE160C is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 136V
• Voltage - Clamping (Max) @ Ipp: within acceptable range (229.95V reference)
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: DO-15 or DO-204AC compatible

Identified Substitute Parts:

The P6KE160CA (Taiwan Semiconductor Corporation) qualifies as a direct substitute, matching the 136V reverse standoff voltage, 600W peak pulse power rating, and DO-15 through-hole package. This part is currently in active production status with 1560 units in stock.

The P6KE550CA (Littelfuse Inc.) is listed in the original part's substitute field but operates at a significantly different voltage level (468V reverse standoff, 760V clamping), making it unsuitable for direct replacement in applications requiring 136V protection.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete P6KE160C, the P6KE160CA from Taiwan Semiconductor Corporation is the appropriate substitute. This part maintains electrical equivalence across all critical parameters: 136V reverse standoff voltage, 600W peak pulse power rating, and identical through-hole DO-15 packaging. Both parts are ROHS3 compliant and rated for the same operating temperature range.

The P6KE160CA is in active production with confirmed inventory availability (1560 units in stock), ensuring long-term supply continuity. The clamping voltage of 219V is lower than the original 229.95V specification, representing improved performance characteristics within acceptable design margins for general-purpose transient suppression applications.

The P6KE550CA, while listed as a substitute in the original part documentation, operates at a fundamentally different voltage class (468V standoff) and is not suitable for direct replacement in circuits designed for 136V protection.

Frequently Asked Questions (FAQ)

Q: Can the P6KE160CA directly replace the P6KE160C without circuit modifications?

A: Yes. The P6KE160CA maintains the same reverse standoff voltage (136V), peak pulse power rating (600W), and through-hole DO-15 package configuration. No circuit modifications are required for direct substitution.

Q: What is the significance of the lower clamping voltage in the P6KE160CA (219V vs. 229.95V)?

A: The lower clamping voltage represents tighter voltage regulation and improved transient suppression performance. This is a beneficial characteristic that does not compromise circuit compatibility.

Q: Why is the P6KE550CA listed as a substitute if it cannot replace the P6KE160C?

A: The P6KE550CA is listed in the original part's substitute field but operates at a different voltage class (468V standoff vs. 136V standoff). This part is suitable only for applications requiring higher-voltage protection and is not a functional equivalent for 136V protection circuits.

Q: Are there any packaging differences between the P6KE160C and P6KE160CA?

A: Both parts use the DO-15 through-hole axial package. The P6KE160CA is supplied in cut tape (CT) packaging format, which is standard for component distribution and does not affect circuit performance.

Q: What compliance certifications apply to the substitute part?

A: The P6KE160CA is ROHS3 compliant and REACH unaffected, matching the regulatory status of the original P6KE160C. Both parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.
