P6KE82CA Equivalent & Substitute Parts

Part Overview

The P6KE82CA is a transient voltage suppressor (TVS) diode designed for general-purpose overvoltage protection applications. This bidirectional Zener diode operates with a reverse standoff voltage of 70.1V and provides clamping at 113V maximum, making it suitable for protecting sensitive electronic circuits from transient voltage spikes. The original Diodes Incorporated P6KE82CA-T is classified as obsolete, necessitating identification of active equivalent parts from alternative manufacturers to maintain design continuity and ensure supply availability.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility): P6KE82CA-B (Littelfuse), P6KE82CA (Taiwan Semiconductor), P6KE82CA-E3/54 (Vishay), and P6KE82CA-TP (Micro Commercial Co) are direct functional equivalents with active product status and full parameter alignment. All maintain ROHS3 compliance and MSL 1 rating. These parts are suitable for immediate design substitution without circuit modification.

Secondary Substitutes (Acceptable with Verification): P6KE82CA-AP and P6KE82CA-BP (Micro Commercial Co) are electrically equivalent with automotive-grade qualification. These parts are appropriate for applications requiring automotive-level reliability.

Specialized Substitutes: P6KE82CAHE3/54 (Vishay) includes AEC-Q101 automotive qualification and is designated for automotive applications. P6KE82CAE3/TR13 (Microsemi) offers axial packaging with slightly reduced operating temperature range (-65°C to 150°C versus -55°C to 175°C).

Limited Compatibility: SA70CA (Taiwan Semiconductor) exhibits minor parameter deviation: reverse standoff voltage of 70V (versus 70.1V), peak pulse current of 4.6A (versus 5.3A), and peak pulse power of 500W (versus 600W). This part is functionally compatible but operates at reduced performance margins and should be selected only when primary substitutes are unavailable.

Frequently Asked Questions (FAQ)

Q: Can P6KE82CA-B from Littelfuse directly replace the obsolete P6KE82CA-T? A: Yes. P6KE82CA-B maintains identical voltage specifications (70.1V standoff, 113V clamping), equivalent peak pulse current (5.4A versus 5.3A), and identical power rating (600W). Both use DO-204AC/DO-15 through-hole packaging. The part is pin-compatible and electrically interchangeable.

Q: What is the difference between DO-15 and DO-204AC packaging? A: DO-15 and DO-204AC are equivalent designations for the same through-hole axial package. Both refer to a two-lead cylindrical component with identical physical dimensions and pin spacing. Parts specified as either designation are mechanically and electrically interchangeable.

Q: Is SA70CA a suitable replacement for P6KE82CA? A: SA70CA is functionally compatible but operates at reduced performance specifications. It provides 70V standoff (versus 70.1V), 4.6A peak pulse current (versus 5.3A), and 500W power rating (versus 600W). Selection should be limited to applications where these reduced margins are acceptable or when primary equivalents are unavailable.

Q: Which substitute parts carry automotive qualification? A: P6KE82CA-AP, P6KE82CA-BP, and P6KE82CAHE3/54 are designated with automotive-grade qualification. P6KE82CAHE3/54 additionally carries AEC-Q101 certification, making it suitable for automotive applications requiring formal qualification documentation.

Q: Are all substitute parts ROHS3 compliant? A: All listed substitute parts except SA70CA explicitly state ROHS3 compliance. SA70CA compliance status is not specified in available documentation. Verify ROHS3 status with the manufacturer if regulatory compliance is required for your application.

Q: What is the inventory availability of substitute parts? A: Current inventory levels vary: P6KE82CA (Taiwan Semiconductor) has 16,750 units available, P6KE82CA-TP has 4,732 units, P6KE82CA-E3/54 has 2,969 units, P6KE82CA-B has 1,044 units, and P6KE82CAE3/TR13 has 1,124 units. Verify current stock with your supplier before design finalization.
