Product details
Overview
P6KE82HE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal 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 peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE82HE3/73 datasheet, P6KE82HE3/73 pinout, P6KE82HE3/73 application, or P6KE82HE3/73 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, surge current capability under 10/1000 μs transients, thermal resistance (20 °C/W junction-to-lead), RoHS and whisker-test compliance (JESD 201 Class 2), and unidirectional polarity marking for correct PCB orientation.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds VBR, it avalanches to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at 70.1 V).
Designed for single-pulse and low-duty-cycle repetitive surges (0.01 %), it delivers fast response (<1 ns), low incremental surge resistance, and robust thermal performance up to 175 °C junction temperature - critical for automotive engine control units and industrial motor drives exposed to load-switching transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains high-energy lightning or ESD-induced transients without failure |
| Breakdown Voltage VBR | 77.9–86.1 V at 1 mA - defines precise avalanche initiation threshold for reliable clamping onset |
| Stand-off Voltage VWM | 70.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| Clamping Voltage VC | 113 V at 5.3 A IPPM - limits voltage seen by protected IC during worst-case surge |
| Operating Temperature Range | −55 °C to +175 °C - supports under-hood automotive and industrial environments |
| Thermal Resistance RθJL | 20 °C/W - enables effective heat transfer to PCB copper pour or lead frame for sustained surge handling |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD |

Use Scenario: Protecting 48 V battery-supplied ECUs from load-dump transients (ISO 16750-2) and alternator switching spikes. IC Role / Device Role / Timing Role: Uni-directional shunt clamp placed between 48 V rail and chassis ground, triggered within nanoseconds upon overvoltage. Use Value: Limits rail voltage to ≤113 V during 100 A/100 ms load dump, preventing damage to MCU, gate drivers, and sensors. |
Use Scenario: Safeguarding digital input channels of programmable logic controllers against induced surges from relay coil flyback or nearby motor switching. IC Role / Device Role / Timing Role: Front-end TVS on 24 V DC input terminals, absorbing energy before it reaches optocoupler or level-shifter ICs. Use Value: Clamps 1 kV/42 Ω surge (IEC 61000-4-5) to <120 V, preserving input stage integrity and system uptime. |
| Telecom DC Power Feeds | Consumer Appliance Motor Control |
|
Use Scenario: Overvoltage suppression on −48 V telecom rectifier outputs exposed to lightning-induced surges on outdoor cable runs. IC Role / Device Role / Timing Role: Reverse-biased TVS referenced to system ground, conducting only during negative-going transients on negative supply rail. Use Value: Withstands 600 W pulses while maintaining <1 μA leakage at −48 V, enabling low-power standby operation. |
Use Scenario: Protecting microcontroller GPIOs and H-bridge gate drivers in washing machine motor inverters from back-EMF spikes. IC Role / Device Role / Timing Role: Localized TVS on low-side MOSFET source lines and MCU analog sensor inputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ80A | DO-214AA package; 80 V VWM, 125 V VC at 4.8 A; 600 W rating; same AEC-Q101 qualification | Surface-mount footprint; higher thermal resistance (RθJA = 40 °C/W vs. 20 °C/W); less effective for high-repetition surges | Select SMBJ80A when board space is constrained and reflow assembly is required; verify PCB copper area for thermal management. |
| 1.5KE82A | Same DO-204AC package; identical VBR (77.9–86.1 V), but commercial-grade only (no AEC-Q101); 1.5 kW rating (10/1000 μs) | Lacks automotive qualification; higher peak power but larger physical size and higher leakage at elevated temperature | Choose 1.5KE82A for cost-sensitive industrial applications where AEC-Q101 is not mandated and surge duty cycle is infrequent. |
Compared with SMBJ80A and 1.5KE82A, P6KE82HE3/73 uniquely balances AEC-Q101 validation, axial-leaded manufacturability, and optimized thermal performance (20 °C/W RθJL) - making it preferred for automotive under-hood modules and high-reliability industrial controls where lead-frame cooling and qualification traceability are mandatory.

FAQ
What is the polarity configuration of P6KE82HE3/73?
P6KE82HE3/73 is a uni-directional TVS diode, meaning it conducts only in reverse bias above its breakdown voltage. The cathode is marked by a color band on the package body, and the anode connects to ground or the lower-potential reference. This configuration ensures no forward conduction during normal operation, minimizing leakage and power loss in P6KE82HE3/73-based protection circuits.
Does P6KE82HE3/73 meet automotive qualification standards?
Yes, P6KE82HE3/73 carries the HE3 suffix, indicating full AEC-Q101 qualification per the Vishay datasheet revision 18-Sep-12. This includes testing for high-temperature operating life, temperature cycling, and electrostatic discharge - confirming suitability for automotive powertrain, body electronics, and ADAS modules where P6KE82HE3/73 serves as primary surge protection.
What is the maximum clamping voltage of P6KE82HE3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE82HE3/73 is 113 V, measured at a peak pulse current (IPPM) of 5.3 A using the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events, ensuring compatibility with 100 V-rated components downstream of P6KE82HE3/73 in 48 V or 60 V systems.
How does the HE3 suffix differ from the E3 suffix in P6KE82HE3/73?
The HE3 suffix in P6KE82HE3/73 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates RoHS-compliant commercial grade only. Both share DO-204AC packaging and identical electrical specs, but P6KE82HE3/73 undergoes additional automotive stress screening - making it the required choice where P6KE82HE3/73 is deployed in vehicle subsystems subject to OEM qualification requirements.
Can P6KE82HE3/73 be used in bi-directional protection applications?
No, P6KE82HE3/73 is strictly uni-directional. For bi-directional transient suppression (e.g., AC lines or differential data buses), Vishay specifies CA-suffix variants such as P6KE82CA. Using P6KE82HE3/73 in bi-directional configurations risks forward conduction and failure during positive half-cycles; always match polarity type to circuit topology - P6KE82HE3/73 is validated only for DC rail or unidirectional signal line protection.
