P6KE82C-B Equivalent & Substitute Parts

Part Overview

The P6KE82C-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This bidirectional Zener diode operates with a reverse standoff voltage of 70.1V and provides clamping at 118.65V maximum. The component is packaged in DO-204AC (DO-15) axial through-hole configuration and is rated for 600W peak pulse power dissipation across an operating temperature range of -55°C to 175°C.

The P6KE82C-B is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6KE82C-B is determined by the following critical parameters:

• Reverse standoff voltage: 70.1V (must match)
• Bidirectional channels: 1 (must match)
• Package type: DO-204AC / DO-15 axial through-hole (must match)
• Peak pulse power rating: 600W (must match)
• Zener diode type (must match)

Substitute parts must maintain identical or functionally equivalent voltage standoff characteristics, identical package configuration for mechanical and electrical compatibility, and equivalent power dissipation capability. Variations in clamping voltage and peak pulse current are permissible within the same product series when the core protection function remains intact.

Engineering Selection Recommendations

P6KE82CA-B (Littelfuse Inc., Active Status)

This part is the direct successor to the P6KE82C-B within the Littelfuse product line. Both components share identical reverse standoff voltage (70.1V), package configuration (DO-204AC / DO-15), and peak pulse power rating (600W). The P6KE82CA-B is currently in active production status, ensuring long-term availability and supply chain stability. The clamping voltage is reduced from 118.65V to 113V, and peak pulse current is specified at 5.4A. Operating temperature range matches the original specification (-55°C to 175°C). ROHS3 compliance and REACH unaffected status confirm regulatory alignment.

P6KE82CA (Taiwan Semiconductor Corporation, Active Status)

This alternative maintains the same reverse standoff voltage (70.1V), package type (DO-15 axial), and power rating (600W). Manufactured by Taiwan Semiconductor Corporation, this part is actively produced and available in high inventory quantities (16,750 pcs). The clamping voltage specification is 113V with peak pulse current of 5.3A. This part is supplied in Tape & Reel packaging, suitable for automated assembly environments. ROHS3 compliance is confirmed.

Both substitute parts satisfy the core electrical and mechanical requirements for replacement. Selection between P6KE82CA-B and P6KE82CA should be based on packaging preference (bulk versus tape & reel), supply chain sourcing strategy, and inventory availability requirements.

Frequently Asked Questions (FAQ)

Q: Can P6KE82CA-B or P6KE82CA be used as direct replacements for P6KE82C-B?

A: Yes. Both parts maintain the critical electrical parameters: 70.1V reverse standoff voltage, 1 bidirectional channel, 600W peak pulse power, and identical DO-204AC / DO-15 axial through-hole package configuration. The clamping voltage reduction from 118.65V to 113V represents a tighter clamping characteristic, which is functionally acceptable for general-purpose overvoltage protection applications within the same voltage class.

Q: What is the difference between P6KE82CA-B and P6KE82CA?

A: Both parts are electrically equivalent with identical reverse standoff voltage (70.1V) and package type (DO-15 axial). The primary differences are manufacturer (Littelfuse Inc. versus Taiwan Semiconductor Corporation), packaging format (bulk versus tape & reel), and peak pulse current specification (5.4A versus 5.3A). The P6KE82CA-B is supplied in bulk packaging, while P6KE82CA is supplied in tape & reel format for automated assembly.

Q: Are there any compliance or regulatory differences between the substitute parts?

A: All three parts (P6KE82C-B, P6KE82CA-B, and P6KE82CA) are ROHS3 compliant. The P6KE82CA-B and P6KE82CA both carry REACH unaffected status. Moisture sensitivity level is rated as 1 (unlimited) for all parts. ECCN and HTSUS classifications are identical across all three components.

Q: Does the change in clamping voltage from 118.65V to 113V affect circuit performance?

A: The clamping voltage reduction represents a tighter voltage clamp, meaning the TVS diode will limit transient voltages to a lower maximum level. This is generally beneficial for component protection. The change is within the same product series and voltage class. Circuit validation should confirm that the lower clamping voltage is compatible with downstream component ratings and system requirements.

Q: What packaging considerations should be evaluated when selecting between substitute parts?

A: P6KE82CA-B is supplied in bulk packaging, suitable for manual assembly, repair, or low-volume production environments. P6KE82CA is supplied in tape & reel format, optimized for high-volume automated assembly processes. Both parts use identical DO-15 axial through-hole package configuration, ensuring mechanical compatibility with existing PCB designs and assembly equipment.
