Product details
Overview
P6KE8.2C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal or power lines. It features a 8.2 V breakdown voltage (VBR min/max = 7.79–8.61 V at 10 mA), 7.02 V stand-off voltage (VWM), 12.1 V maximum clamping voltage (VC) at 49.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE8.2C-E3/73 datasheet, P6KE8.2C-E3/73 pinout, P6KE8.2C-E3/73 application, or P6KE8.2C-E3/73 equivalent, this device delivers verified bi-directional clamping performance, AEC-Q101 qualification (via HE3 variant lineage), DO-15 package compatibility, and low thermal resistance (RθJL = 20 °C/W) critical for high-reliability transient suppression in space-constrained designs.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle.
The device is rated for -55 °C to +175 °C operating junction temperature, supports 100 A non-repetitive forward surge current (IFSM), and exhibits a 0.065 %/°C temperature coefficient of VBR, ensuring predictable voltage threshold drift over temperature in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V at 10 mA - defines reliable conduction onset window for transient detection and clamping initiation |
| VWM | 7.02 V - maximum continuous working voltage before leakage exceeds 200 µA; sets safe DC bias margin |
| VC @ IPPM | 12.1 V at 49.6 A - peak clamped voltage during 600 W transient; determines protected circuit's maximum overvoltage stress |
| PPPM | 600 W (10/1000 µs) - surge energy handling capacity; enables robust protection against ISO 7637-2 Pulse 1/2a/5a in automotive systems |
| IPPM | 49.6 A - peak pulse current capability; directly correlates to survivability against 500 V/50 Ω lightning surges per IEC 61000-4-5 |
| TJ max | +175 °C - high junction temperature rating allows operation in under-hood automotive or enclosed industrial enclosures |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports sustained power dissipation without external heatsinking |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads; RoHS-compliant (E3 suffix), UL 94 V-0 rated compound.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting 5 V analog sensor outputs (e.g., pressure, temperature) from load dump and inductive switching transients in 12 V vehicle systems. IC Role / Device Role: Bi-directional voltage clamp placed between signal line and ground, shunting surge energy before it reaches ADC input or op-amp buffer. Use Value: Clamps transients to ≤12.1 V while maintaining 7.02 V stand-off, preventing damage to 5 V rail-tied front-end circuitry without affecting normal signal integrity. |
Use Scenario: Safeguarding 0–10 V or 4–20 mA analog inputs on programmable logic controllers exposed to field wiring surges in factory automation. IC Role / Device Role: Primary transient suppressor mounted at connector entry point, coordinated with series impedance and filtering. Use Value: Absorbs up to 600 W of surge energy per event, enabling system-level compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) without derating or parallel devices. |
| Consumer USB Port ESD Protection | Telecom Line Card Surge Suppression |
Use Scenario: Secondary-level protection on USB 2.0 D+/D− lines after integrated ESD diodes, targeting higher-energy events like contact discharge beyond ±15 kV. IC Role / Device Role: Coordinated clamping device with higher power rating than monolithic ESD arrays, placed upstream of data-line filters. Use Value: Provides 49.6 A peak pulse current handling and 12.1 V clamping to prevent latch-up or gate oxide rupture in USB transceivers during multi-kV transients. |
Use Scenario: Protecting Ethernet PHY interfaces or FXS line drivers on telecom access equipment subjected to lightning-induced surges on copper pairs. IC Role / Device Role: First-stage protector on tip/ring lines, paired with gas discharge tube (GDT) for coordination and follow-on current limiting. Use Value: Delivers 600 W surge capability with bi-directional symmetry, enabling robust coordination with GDTs while maintaining low capacitance (<100 pF) to preserve signal integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | DO-214AA package; 8.0 V VWM, 12.0 V VC @ 49.2 A; lower RθJA but surface-mount only | Requires PCB redesign for SMD layout; better thermal performance in dense layouts but no through-hole option | Select when board space is constrained and reflow assembly is available; not drop-in for DO-15 footprints |
| P6KE8.2CA | Same DO-15 package and electrical specs; differs only in packaging suffix (no /73 tape-and-reel indicator) | Identical function and form; /73 denotes 750-piece bulk pack per Vishay ordering code | Direct physical and electrical substitute; use P6KE8.2CA-E3/73 if exact packaging configuration is required |
Compared with SMBJ8.0CA and P6KE8.2CA, the P6KE8.2C-E3/73 offers verified through-hole manufacturability, AEC-Q101 lineage, and standardized 750-unit bulk packaging - making it optimal for prototyping, low-volume automotive modules, and legacy through-hole production where solderability and mechanical retention are prioritized.

FAQ
What does the "C" suffix indicate in P6KE8.2C-E3/73?
The "C" in P6KE8.2C-E3/73 denotes bi-directional polarity - meaning the device provides symmetrical transient suppression in both forward and reverse directions, with identical VBR, VC, and leakage characteristics across polarity. This is confirmed in Vishay's datasheet section "DEVICES FOR BI-DIRECTION APPLICATIONS", where CA suffixes explicitly designate bi-directional types. The P6KE8.2C-E3/73 has no cathode band marking, consistent with bi-directional construction.
Is P6KE8.2C-E3/73 AEC-Q101 qualified?
The P6KE8.2C-E3/73 itself carries the commercial-grade E3 suffix, but its HE3 variant (e.g., P6KE8.2CHE3) is explicitly AEC-Q101 qualified per datasheet Note (1) and Mechanical Data section. Since the P6KE8.2C-E3/73 shares identical die, construction, and process with the HE3 version - differing only in test screening level - it inherits the same underlying qualification basis and is widely accepted in automotive applications where full AEC-Q101 certification is specified at part family level.
What is the maximum clamping voltage of P6KE8.2C-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE8.2C-E3/73 is 12.1 V, measured at its peak pulse current (IPPM) of 49.6 A using a 10/1000 µs waveform. This value is specified in the Electrical Characteristics table on page 2 of the Vishay datasheet (Document Number: 88369) and represents the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can P6KE8.2C-E3/73 be used in place of uni-directional P6KE8.2A-E3/73?
No - P6KE8.2C-E3/73 is bi-directional and lacks polarity marking, while P6KE8.2A-E3/73 is uni-directional with a cathode band. Substituting them requires circuit verification: the bi-directional version clamps in both directions, which may interfere with DC-biased signal paths or cause unintended conduction in rectified supplies. Use P6KE8.2C-E3/73 only where true bi-directional protection is intended and validated in the target application.
What is the thermal resistance from junction to lead (RθJL) for P6KE8.2C-E3/73?
The junction-to-lead thermal resistance (RθJL) for P6KE8.2C-E3/73 is 20 °C/W, as specified in the Thermal Characteristics table on page 3 of the Vishay datasheet. This value enables accurate thermal modeling of power dissipation during repetitive surge events and confirms suitability for lead-mounted heat sinking in compact industrial or automotive control modules without additional thermal vias or pads.
