Product details
Overview
P6KE8.2-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection on DC power rails and signal lines. It features a 7.79 V minimum breakdown voltage (VBR), 7.02 V maximum stand-off voltage (VWM), 12.1 V clamping voltage (VC) at 49.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and consumer power supply inputs.
For engineers reviewing the P6KE8.2-E3/73 datasheet, P6KE8.2-E3/73 pinout, P6KE8.2-E3/73 application, or P6KE8.2-E3/73 equivalent, key selection criteria include its DO-15 package compatibility, 100 A non-repetitive surge capability (IFSM), low 0.065 %/°C VBR temperature coefficient, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (<1 µA leakage at 7.02 V), then rapidly avalanches below 12.1 V to divert transient energy away from downstream ICs. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and repeatable clamping performance across temperature.
Designed for 10/1000 µs surge waveforms per IEC 61000-4-5, it delivers 600 W peak pulse power with <1 ns response time and 20 °C/W junction-to-lead thermal resistance - enabling effective protection of MOSFET gates, microcontroller I/O pins, and CAN transceiver power rails without derating at board-level ambient temperatures up to 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.02 V - Maximum continuous reverse operating voltage before leakage exceeds 200 µA; defines safe DC rail margin for 5 V or 6 V systems. |
| VBR (min/max) | 7.79 V / 8.61 V at 10 mA - Tight 5 % tolerance ensures predictable turn-on across production lots and temperature range. |
| VC @ IPPM | 12.1 V at 49.6 A - Clamping voltage limits protected circuit stress during 600 W transient events; enables robust 3.3 V/5 V logic interface protection. |
| IPPM | 49.6 A - Peak pulse current capacity with 10/1000 µs waveform; supports EN 61000-4-5 Level 4 (4 kV) surge immunity design. |
| TJ max | +175 °C - High junction temperature rating allows operation in under-hood automotive or enclosed industrial enclosures without thermal shutdown. |
| RθJL | 20 °C/W - Low junction-to-lead thermal resistance enables efficient heat transfer to PCB copper pour or heatsinked leads. |
| Leakage @ VWM | 200 µA - Ultra-low reverse leakage preserves battery life in always-on sensor nodes and low-power IoT endpoints. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during forward surge events (e.g., reverse polarity connection). |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., +5 V rail); avalanches into low-impedance state when transient exceeds VWM. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures ±5 % VBR tolerance and long-term stability under thermal cycling and humidity exposure. |
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 surge immunity up to 4 kV in Level 4 applications without external series impedance. |
| AEC-Q101 qualified (HE3 variant) | Validated for automotive under-hood use including engine control units, body electronics, and ADAS sensor interfaces. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns response), reducing risk of latch-up in CMOS ICs. |
| UL 94 V-0 flammability rating | Molding compound self-extinguishes under flame exposure - required for safety-critical industrial and medical auxiliary circuits. |
Applications
| Automotive Sensor Protection | Industrial PLC Input Protection |
|---|---|

IC Role / Device Role / Timing Role: Fast-acting crowbar element parallel to output capacitor, activated before downstream USB port controllers experience overstress. Use Value: Clamps to 12.1 V within nanoseconds, protecting Type-C CC logic and VBUS switch FETs rated for 20 V absolute maximum. |
Use Scenario: ESD and surge protection on VBUS lines of USB-C receptacles subjected to hot-plug insertion and cable discharge events. IC Role / Device Role / Timing Role: First-line defense against contact discharge (IEC 61000-4-2 ±15 kV) and indirect lightning-induced surges. Use Value: Withstands 49.6 A peak pulse while holding clamping voltage below 15 V - preserving PD controller communication integrity during fault events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | DO-214AA package; 8.0 V VWM, 12.0 V VC @ 49.2 A; same 600 W rating but higher thermal resistance (RθJA = 110 °C/W). | Better suited for surface-mount layouts with limited board space; less effective in high-ambient-temperature through-hole designs. | Select SMBJ8.0A only when SMT assembly is mandatory and thermal management via copper pour is feasible. |
| 1.5KE8.2A | Same DO-15 package; identical VWM/VBR/VC specs but rated for 1500 W peak pulse power (10/1000 µs); larger die size increases capacitance (≈150 pF vs. ≈80 pF). | Preferred for high-energy surge zones (e.g., AC mains input filters); excessive capacitance may distort high-speed data lines. | Choose 1.5KE8.2A where surge threat level exceeds IEC 61000-4-5 Level 4; avoid in signal-line applications above 1 MHz. |
Compared with SMBJ8.0A and 1.5KE8.2A, P6KE8.2-E3/73 offers optimal balance of low-profile axial mounting, proven AEC-Q101 reliability, and minimal parasitic capacitance - making it the preferred choice for cost-sensitive, thermally constrained, and automotive-qualified 5–12 V rail protection.

FAQ
What is the maximum clamping voltage of the P6KE8.2-E3/73 under standard test conditions?
The P6KE8.2-E3/73 has a maximum clamping voltage (VC) of 12.1 V when subjected to its rated peak pulse current of 49.6 A using a 10/1000 µs waveform. This value is measured per JEDEC standards and guarantees that downstream components see no more than 12.1 V during worst-case transient events, making P6KE8.2-E3/73 suitable for safeguarding 5 V and 3.3 V logic interfaces without additional series impedance.
Is the P6KE8.2-E3/73 RoHS compliant and halogen-free?
Yes, the P6KE8.2-E3/73 carries the "E3" suffix indicating full RoHS compliance per Directive 2011/65/EU and halogen-free status per JEDEC JS709A. The device uses matte tin-plated leads and UL 94 V-0 epoxy molding compound, meeting environmental requirements for consumer, industrial, and automotive electronics without exemptions.
Can the P6KE8.2-E3/73 be used in automotive applications?
The P6KE8.2-E3/73 itself is commercial-grade; however, its HE3-suffix variant (P6KE8.2AHE3/73) is AEC-Q101 qualified and approved for automotive use. For under-hood or chassis-mounted applications requiring qualification, specify the HE3 version - P6KE8.2-E3/73 remains suitable for non-qualified automotive subsystems such as infotainment power rails where full AEC validation is not mandated.
What is the thermal resistance specification for the P6KE8.2-E3/73?
The P6KE8.2-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W under standard test conditions. These values enable reliable operation at full 600 W pulse power when leads are soldered to ≥1 cm² copper pour, supporting continuous use in ambient temperatures up to 75 °C without derating - critical for P6KE8.2-E3/73 deployment in enclosed industrial enclosures.
How does the P6KE8.2-E3/73 compare to bi-directional TVS diodes like P6KE8.2CA?
The P6KE8.2-E3/73 is unidirectional and intended for DC line protection with polarity-aware placement (cathode toward protected line), whereas P6KE8.2CA provides symmetrical clamping for AC or bidirectional signal lines. P6KE8.2-E3/73 offers lower leakage (<200 µA) and tighter VBR tolerance than its bi-directional counterpart, making it preferable for precision DC rail protection - but unsuitable for floating or AC-coupled paths where P6KE8.2CA would be required instead.
