Product details
Overview
P6KE82CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 70.1 V minimum breakdown voltage (VBR), 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current, and operates across -55 °C to +175 °C junction temperature - deployed in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE82CA-E3/54 datasheet, P6KE82CA-E3/54 pinout, P6KE82CA-E3/54 application, or P6KE82CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B for telecom and automotive transient protection.
Technical Context
This device implements a glass-passivated silicon avalanche junction optimized for fast response (<1 ns) to ESD and lightning-induced surges. Its bidirectional structure enables symmetrical clamping without polarity sensitivity, supporting both AC-coupled and floating signal line protection.
The P6KE82CA-E3/54 delivers stable clamping performance under repetitive 0.01 % duty cycle pulses, with low incremental surge resistance and thermal derating per Fig. 2 (up to 175 °C TJ). It meets JESD 22-B106 soldering requirements (275 °C, 10 s) and JESD 201 Class 1A whisker testing.

|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive switching spikes in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and ground, absorbing transients before they reach sensitive analog front-ends. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V sensor signal conditioning ICs during 12 V/24 V system load dump events. |
Use Scenario: Safeguarding RS-485/RS-232 communication ports on PLCs and motor drives against EFT and surge coupling from adjacent power circuits. IC Role / Device Role / Timing Role: Primary line-to-ground TVS on differential data lines, activated within <1 ns to limit voltage excursion below receiver absolute maximum ratings. Use Value: Maintains data integrity by clamping common-mode surges up to ±113 V while preserving signal rise/fall times due to low junction capacitance. |
| Telecom Line Protection | Consumer Power Adapter Input |
Use Scenario: Secondary-level surge protection on telephone line interface cards (SLIC) and VoIP gateway Ethernet PHY ports. IC Role / Device Role / Timing Role: UL 497B-recognized protector bridging tip/ring lines to chassis ground, coordinating with primary GDT or MOV stages. Use Value: Enables compliance with GR-1089-CORE telecom immunity requirements without adding board space for multi-stage designs. |
Use Scenario: Input-stage transient suppression on AC-DC adapters for smart home devices, preventing failure during mains-borne surges. IC Role / Device Role / Timing Role: First-line defense on bridge rectifier output, clamping voltage spikes induced by lightning or switching transients on 100–240 VAC input. Use Value: Extends adapter lifetime by limiting peak voltage seen by bulk capacitor and primary-side controller ICs to ≤113 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85CA | DO-214AA package; 85 V VWM, 137 V VC @ 4.4 A; 600 W rating; lower RθJA (50 °C/W vs. 75 °C/W) | Better thermal performance in surface-mount layouts; requires PCB rework for SMD vs. through-hole DO-15 | Select SMBJ85CA when board space is constrained and automated assembly is preferred. |
| 1.5KE82CA | Same DO-15 package; higher 1500 W PPPM; 77.9–86.1 V VBR; 129 V VC @ 11.6 A; larger junction area | Higher surge margin for infrequent but extreme transients (e.g., utility grid coupling); higher clamping voltage | Choose 1.5KE82CA where legacy 1.5 kW surge standards apply and VC margin allows. |
Compared with SMBJ85CA and 1.5KE82CA, the P6KE82CA-E3/54 offers optimal balance of through-hole manufacturability, AEC-Q101 qualification, and precise 113 V clamping for cost-sensitive automotive and industrial designs requiring UL recognition.

FAQ
What is the clamping voltage of the P6KE82CA-E3/54 under a 10/1000 μs surge?
The P6KE82CA-E3/54 has a maximum clamping voltage (VC) of 113 V at 5.3 A peak pulse current under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88369 and ensures downstream components see limited overvoltage during transient events. The P6KE82CA-E3/54 maintains this clamping performance across its full operating temperature range.
Is the P6KE82CA-E3/54 suitable for automotive applications?
Yes, the P6KE82CA-E3/54 is AEC-Q101 qualified and rated for junction temperatures from -55 °C to +175 °C, making it suitable for under-hood and cabin automotive modules. Its bidirectional clamping, DO-15 mechanical robustness, and UL 497B recognition support use in CAN, LIN, and sensor interface protection. The P6KE82CA-E3/54 meets automotive ESD and surge immunity requirements when applied per Vishay's recommended layout guidelines.
How does the P6KE82CA-E3/54 differ from unidirectional P6KE82A variants?
The P6KE82CA-E3/54 is bidirectional with symmetrical clamping characteristics in both polarities, while P6KE82A is unidirectional and features a cathode band marking. The CA suffix indicates identical VBR (77.9–86.1 V), VWM (70.1 V), and VC (113 V) specs but enables protection of AC-coupled or floating lines without polarity concerns. The P6KE82CA-E3/54 eliminates need for orientation verification during manual assembly.
What is the thermal resistance of the P6KE82CA-E3/54, and how does it affect PCB layout?
The P6KE82CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. This means effective heat dissipation relies on adequate copper pour connected to both leads - especially critical during repetitive surge events. For sustained operation near 5.0 W power dissipation, PCB layout must provide ≥1 cm² of 2-oz copper per lead. The P6KE82CA-E3/54 performs reliably in standard through-hole mounting without additional heatsinking under intermittent surge conditions.
Does the P6KE82CA-E3/54 meet UL safety certification requirements?
Yes, the P6KE82CA-E3/54 carries Underwriters Laboratories recognition under UL 497B (file E136766) for both unidirectional and bidirectional transient protectors. This certification validates its performance in telecom and data line protection applications, including voltage limiting, energy absorption, and fail-safe short-circuit behavior. The P6KE82CA-E3/54 complies with QVGQ2 classification and supports system-level UL listing when used per Vishay's application notes.
