Product details
Overview
P6KE8.2C-E3/54 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), 7.79–8.61 V breakdown voltage at 10 mA, 7.02 V stand-off voltage, 12.1 V maximum clamping voltage at 49.6 A peak pulse current, 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 P6KE8.2C-E3/54 datasheet, P6KE8.2C-E3/54 pinout, P6KE8.2C-E3/54 application, or P6KE8.2C-E3/54 equivalent, key selection criteria include bi-directional clamping capability, UL 497B recognition, AEC-Q101 qualification (HE3 variant), DO-15 mechanical compatibility, and 12.1 V clamping threshold at rated surge current.
Technical Context
The P6KE8.2C-E3/54 implements a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low dynamic impedance under surge conditions. Its bi-directional architecture enables symmetric clamping across both polarities without external polarity management.
It complies with ANSI/IEEE C62.35 surge test standards and supports repetitive 0.01% duty cycle pulses. Thermal resistance is 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient), enabling operation up to 175 °C junction temperature with appropriate PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 7.79–8.61 V at 10 mA - defines minimum voltage at which device enters avalanche conduction in either direction |
| Stand-off Voltage VWM | 7.02 V - maximum continuous reverse working voltage before leakage exceeds 200 μA |
| Clamping Voltage VC | 12.1 V at 49.6 A IPPM - limits transient voltage seen by protected circuit during 10/1000 μs surge |
| Peak Pulse Power | 600 W (10/1000 μs waveform) - determines maximum single-event energy absorption capability |
| Operating Temperature | –55 °C to +175 °C - supports under-hood automotive and industrial environments without derating |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.300" lead spacing and UL 94 V-0 molded epoxy |
| RoHS Compliance | E3 suffix - RoHS-compliant matte tin-plated leads, JESD 201 Class 1A whisker tested |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body, 0.300" (7.6 mm) minimum lead length, 0.104" (2.6 mm) diameter body, matte tin-plated leads solderable per J-STD-02 and JESD 22-B102. Bi-directional construction means no cathode marking; terminals are non-polarized.

|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and ESD events in vehicle cabins. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed between signal line and ground, responding within <1 ns to transients exceeding 7.02 V. Use Value: Limits induced surges to ≤12.1 V, preventing damage to 5 V or 3.3 V rail-tied receivers while maintaining signal integrity during normal operation. |
Use Scenario: Safeguarding 4–20 mA current loop inputs and ±10 V analog inputs in programmable logic controllers against field wiring surges and lightning-induced coupling. IC Role / Device Role / Timing Role: Standoff-mode protector mounted at connector entry point, conducting only during >7.02 V transients with sub-nanosecond response. Use Value: Enables compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) without adding series impedance or signal distortion. |
| Consumer USB Port ESD Protection | Telecom Line Card Surge Suppression |
Use Scenario: Secondary-level ESD protection on USB 2.0 D+/D– lines behind primary polymer-based TVS, handling contact discharge up to ±15 kV. IC Role / Device Role / Timing Role: Fast-clamping bi-directional suppressor placed adjacent to USB connector, shunting ESD current to ground. Use Value: Clamps ESD pulses to 12.1 V within nanoseconds, preventing latch-up or gate oxide rupture in USB transceivers operating at 3.3 V. |
Use Scenario: Primary surge protection on telephone line interfaces (POTS, xDSL) exposed to lightning-induced longitudinal surges on tip/ring pairs. IC Role / Device Role / Timing Role: Bi-directional high-energy clamp installed before hybrid transformer, rated for 600 W unidirectional surges per line pair. Use Value: Absorbs 10/1000 μs surges up to 49.6 A while maintaining ≤12.1 V differential across protected circuitry, meeting UL 497B requirements. |
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 nominal VBR, 100 W lower peak pulse power (500 W), 12.5 V VC at 40 A | Smaller footprint but lower surge rating; suited for space-constrained consumer designs with moderate threat levels | Select SMBJ8.0CA when board space is limited and surge requirements do not exceed IEC 61000-4-5 Level 3 |
| 1.5KE8.2C | Same DO-204AC package, identical VBR and VC, but 1.5 kW peak pulse power (10/1000 μs) and higher IPPM (123 A) | Higher energy handling for critical infrastructure or utility-grade equipment facing severe lightning exposure | Choose 1.5KE8.2C where system-level testing requires >600 W surge margin or longer-duration transients are expected |
Compared with SMBJ8.0CA, P6KE8.2C-E3/54 offers 20% higher surge power and proven AEC-Q101 qualification; versus 1.5KE8.2C, it trades peak energy capacity for tighter VC consistency and lower cost in commercial-grade applications.

FAQ
What is the polarity configuration of P6KE8.2C-E3/54?
P6KE8.2C-E3/54 is a bi-directional TVS diode, meaning it provides symmetrical clamping for positive and negative transients without cathode marking. Its "C" suffix explicitly denotes bi-directional functionality, unlike "A"-suffixed uni-directional variants. This allows direct placement across any two points needing bidirectional overvoltage protection, such as data lines or AC-coupled signals. The device conducts in avalanche mode regardless of voltage polarity once the breakdown threshold is exceeded.
Does P6KE8.2C-E3/54 meet automotive qualification standards?
P6KE8.2C-E3/54 itself carries the commercial-grade E3 suffix and is not AEC-Q101 qualified; however, the functionally identical P6KE8.2CHE3/54 variant is AEC-Q101 qualified. Both share identical electrical parameters, DO-204AC packaging, and UL 497B recognition. For automotive applications requiring formal qualification, P6KE8.2CHE3/54 must be specified - the "HE3" suffix confirms AEC-Q101 compliance per the Vishay datasheet revision 18-Sep-12.
What is the maximum clamping voltage of P6KE8.2C-E3/54 under surge conditions?
The maximum clamping voltage of P6KE8.2C-E3/54 is 12.1 V, measured at its rated peak pulse current of 49.6 A using a 10/1000 μs waveform. This value represents the upper limit of voltage imposed on the protected circuit during worst-case surge events. It is derived from the device's low dynamic impedance and stable avalanche characteristics, ensuring downstream components see no more than 12.1 V even under full-rated surge stress.
Can P6KE8.2C-E3/54 be used in place of a uni-directional TVS like P6KE8.2A?
No - P6KE8.2C-E3/54 cannot directly replace P6KE8.2A because they differ fundamentally in polarity behavior. P6KE8.2A is uni-directional with a defined cathode (band-marked) and conducts only in reverse bias, while P6KE8.2C-E3/54 is bi-directional and unmarked. Substituting one for the other risks incorrect biasing, failure to clamp positive transients (if replacing "C" with "A"), or forward conduction during normal operation (if replacing "A" with "C"). Always match suffix ("A" vs "C") to circuit polarity requirements.
What is the thermal resistance specification for P6KE8.2C-E3/54?
P6KE8.2C-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W at TA = 25 °C. These values assume standard PCB mounting with 0.375" (9.5 mm) lead lengths. Effective heat dissipation relies on adequate copper pour connected to both leads; doubling copper area reduces RθJA by ~15–20%. The 175 °C max junction temperature allows operation in high-ambient environments when thermal design is validated.
