Product details
Overview
P6KE82C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 77.9 V to 86.1 V breakdown voltage at 1 mA, 70.1 V stand-off voltage, 113 V maximum clamping voltage at 5.3 A, and operates from –55 °C to +175 °C - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE82C-E3/73 datasheet, P6KE82C-E3/73 pinout, P6KE82C-E3/73 application, or P6KE82C-E3/73 equivalent, this page delivers verified electrical parameters, thermal behavior, clamping performance under surge conditions, RoHS-compliant packaging details, and AEC-Q101 qualification status - all critical for ESD/transient immunity validation in safety-critical embedded systems.
Technical Context
The P6KE82C-E3/73 implements a silicon avalanche junction structure with glass passivation, enabling sub-nanosecond response to fast-rising transients. Its bi-directional configuration supports symmetrical clamping across both polarities without polarity marking, and it complies with AEC-Q101 for automotive-grade reliability.
It delivers 600 W peak pulse power per 10/1000 μs waveform at TA = 25 °C, derates linearly above 25 °C with RθJA = 75 °C/W, and maintains clamping voltage ≤113 V up to 5.3 A IPPM - ensuring predictable overvoltage limiting during lightning-induced or inductive-switching surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 77.9 V min / 86.1 V max at 1 mA - defines the voltage threshold at which avalanche conduction begins in either polarity |
| Stand-off Voltage (VWM) | 70.1 V - maximum continuous reverse working voltage before leakage exceeds 1 μA; sets safe operating margin below VBR |
| Clamping Voltage (VC) | 113 V at 5.3 A IPPM - maximum voltage seen by protected circuit during worst-case 10/1000 μs surge |
| Peak Pulse Power (PPPM) | 600 W - energy-handling capability for transient suppression without failure under standardized surge waveform |
| Peak Pulse Current (IPPM) | 5.3 A - maximum non-repetitive surge current the device can safely clamp at rated VC |
| Junction Temperature Range | –55 °C to +175 °C - enables operation in under-hood automotive, industrial motor drives, and outdoor telecom equipment |
| Package | DO-204AC (DO-15) - axial-leaded, UL 94 V-0 molded epoxy case with matte tin-plated leads per J-STD-002 |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body, no polarity marking for bi-directional operation. Leads are matte tin-plated and solderable per J-STD-002; compliant with JESD 201 Class 1A whisker test (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Lead 1 / Lead 2 | Connection to PCB trace or wire harness | Leads provide mechanical mounting and low-inductance path to ground or rail; length impacts surge impedance |
Key Features
| Feature | Design Value |

| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out with low-inductance grounding |
| AEC-Q101 qualified | Validated for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving clamping precision beyond VBR tolerance |
| UL 94 V-0 flammability rating | Ensures flame-retardant behavior under fault conditions, meeting safety requirements for industrial enclosures |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

IC Role / Device Role / Timing Role: Mounted across motor terminals to clamp flyback spikes before they propagate into MCU GPIO or driver ICs. Use Value: 70.1 V stand-off voltage matches typical 24–48 V motor supply rails, avoiding false triggering during normal commutation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85CA | DO-214AA package, 85 V standoff, 600 W rating, lower RθJA (50 °C/W), higher capacitance (~100 pF) | Better thermal performance but larger footprint; suited for PCB-mounted surface-mount layouts | Select SMBJ85CA when board space allows SMT placement and improved thermal dissipation is required. |
| 1.5KE82CA | Same DO-204AC package, identical VWM/VBR/VC specs, but rated for 1500 W peak power (10/1000 μs) | Higher surge capacity for infrequent but extreme events (e.g., direct lightning coupling) | Choose 1.5KE82CA where legacy through-hole layout must support higher-energy transients without redesign. |
Compared with P6KE82C-E3/73, SMBJ85CA offers superior thermal management in SMT form but requires layout change, while 1.5KE82CA retains identical pinout and footprint yet doubles peak power handling - making it ideal for upgrading existing DO-15 designs against more severe surge threats.

FAQ
What is the polarity configuration of P6KE82C-E3/73?
The P6KE82C-E3/73 is a bi-directional TVS diode with symmetrical avalanche characteristics in both directions. It has no polarity marking on the DO-204AC package, and either lead may serve as anode or cathode depending on transient polarity - enabling straightforward placement across unidirectional or differential signal lines without orientation concerns.
Is P6KE82C-E3/73 qualified for automotive use?
Yes, P6KE82C-E3/73 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. The qualification covers temperature cycling, humidity testing, and surge endurance - validating reliability under harsh vehicular operating conditions.
What is the maximum clamping voltage of P6KE82C-E3/73 under surge conditions?
The maximum clamping voltage of P6KE82C-E3/73 is 113 V at 5.3 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value represents the upper bound voltage imposed on protected circuitry during worst-case transient events, ensuring downstream ICs remain within safe operating limits.
Does P6KE82C-E3/73 meet RoHS requirements?
Yes, P6KE82C-E3/73 carries the "E3" suffix indicating full RoHS compliance per Directive 2011/65/EU. Its matte tin-plated leads and UL 94 V-0 epoxy molding compound satisfy environmental and safety standards for commercial and industrial electronics manufacturing.
How does P6KE82C-E3/73 compare to uni-directional P6KE82A-E3/73?
P6KE82C-E3/73 is the bi-directional variant, while P6KE82A-E3/73 is uni-directional with a cathode band marking. Both share identical VBR (77.9–86.1 V), VWM (70.1 V), and VC (113 V) ratings, but P6KE82C-E3/73 supports symmetrical clamping essential for AC-coupled or differential signals - unlike the uni-directional version, which only clamps negative transients relative to its marked cathode.
