Product details
Overview
P6KE82-E3/54 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 77.9 V minimum breakdown voltage (VBR), 70.1 V standoff voltage (VWM), 113 V maximum clamping voltage at 5.3 A peak pulse current, 600 W peak pulse power rating with 10/1000 µs waveform, and operates across –55 °C to +175 °C junction temperature range - deployed in automotive body control modules to protect CAN transceivers from load-dump-induced surges.
For engineers reviewing the P6KE82-E3/54 datasheet, P6KE82-E3/54 pinout, P6KE82-E3/54 application, or P6KE82-E3/54 equivalent, key selection criteria include verified clamping performance under 10/1000 µs surge, thermal resistance (RθJL = 20 °C/W), RoHS-compliant matte tin-plated leads per J-STD-002, AEC-Q101 qualification status, and DO-204AC (DO-15) package compatibility with standard through-hole reflow profiles.
Technical Context
This device operates as a voltage-clamped crowbar element: when reverse-biased voltage exceeds VWM (70.1 V), it transitions from high-impedance blocking to low-impedance conduction at VBR ≥ 77.9 V, limiting transient energy via controlled avalanche breakdown. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and repeatable breakdown characteristics across temperature.
Clamping behavior is defined at IPPM = 5.3 A (10/1000 µs), delivering VC ≤ 113 V - a critical design margin for 72 V nominal systems where downstream ICs require <120 V absolute maximum rating. Thermal derating follows a linear curve above 25 °C ambient, with full 5.0 W power dissipation only at lead temperature ≤75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 70.1 V - maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected line's steady-state DC level |
| VBR (min) | 77.9 V at 1 mA - guaranteed avalanche initiation threshold; ensures reliable turn-on before downstream component damage |
| VC (max) | 113 V at 5.3 A, 10/1000 µs - peak clamped voltage seen by protected circuit; defines worst-case stress during surge |
| PPPM | 600 W - surge energy handling capacity; supports single-event transients up to 600 W without degradation |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; enables accurate PCB copper pour sizing for thermal management |
| TJ max | +175 °C - maximum junction temperature; allows operation in under-hood automotive environments |
| Package | DO-204AC (DO-15) - standardized axial-leaded through-hole package with 0.300" lead spacing; compatible with legacy wave-solder tooling |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking; leads are matte tin-plated, solderable per J-STD-002; meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / reverse surge return path | Connected to system ground or low-impedance return plane; must handle 100 A non-repetitive IFSM during fault |
| Cathode | Reverse-biased input / surge injection point | Connected to protected line (e.g., 72 V battery rail); color band identifies this terminal; withstands 113 V clamping during surge |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5 %) and low leakage (<1 µA at VWM) over lifetime and temperature cycling |
| 600 W peak pulse power (10/1000 µs) | Handles automotive load-dump transients (ISO 7637-2 Pulse 5a) without degradation when properly heatsinked |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive electronics use including engine control units and body domain controllers |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 10605 ESD), improving protection fidelity |
| RoHS-compliant matte tin plating | Enables lead-free reflow compatibility and eliminates whisker risk (JESD 201 Class 1A certified) |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ80A | DO-214AA package; 80 V VWM; 125 V VC at 4.8 A; lower 600 W rating but higher IPPM density due to surface-mount thermal path | Requires SMT layout change; better suited for space-constrained PCBs with thermal vias | Select SMBJ80A when board real estate is limited and thermal vias can be implemented for RθJA reduction |
| 1.5KE82A | Same DO-204AC package; identical VWM/VBR/VC specs; higher 1.5 kW PPPM rating but larger 1.5 kW package footprint and 1.1 g weight | Compatible pinout but requires larger cutout and heavier mechanical support | Choose 1.5KE82A only when system-level surge testing exceeds 600 W requirements (e.g., MIL-STD-1275E) |
Compared with SMBJ80A and 1.5KE82A, P6KE82-E3/54 delivers optimal balance of proven automotive reliability (AEC-Q101), compact DO-15 fit, and precise 70.1 V standoff for 72 V systems - making it preferred for cost-sensitive, through-hole production where thermal mass and legacy assembly compatibility are prioritized.

FAQ
What is the clamping voltage of P6KE82-E3/54 under standard 10/1000 µs surge conditions?
The P6KE82-E3/54 has a maximum clamping voltage (VC) of 113 V when subjected to its rated peak pulse current of 5.3 A using the 10/1000 µs waveform. This value is measured per JEDEC standards and represents the highest voltage the protected circuit will experience during a defined transient event. The P6KE82-E3/54 maintains this clamping performance across its specified operating temperature range.
Is P6KE82-E3/54 qualified for automotive applications?
Yes, the P6KE82-E3/54 is AEC-Q101 qualified, as confirmed by Vishay's documentation for the E3 suffix variant. It is rated for operation from –55 °C to +175 °C junction temperature and validated for use in automotive subsystems including body electronics and power distribution modules. The P6KE82-E3/54 meets the stress test requirements defined in AEC-Q101 for transient voltage suppressors.
What does the "E3/54" suffix indicate in P6KE82-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance. The "/54" indicates the preferred package code for 13-inch paper tape and reel delivery, with a base quantity of 4000 units per reel. This packaging format ensures compatibility with automated through-hole insertion equipment used in high-volume manufacturing of the P6KE82-E3/54.
How does P6KE82-E3/54 differ from bi-directional P6KE82CA variants?
The P6KE82-E3/54 is unidirectional, featuring a cathode band marking and conducting only in reverse bias above VBR; it blocks forward current beyond ~3.5 V. In contrast, P6KE82CA is bi-directional with symmetrical clamping in both polarities and no polarity marking. The P6KE82-E3/54 is selected for DC rail protection where polarity is fixed, whereas P6KE82CA suits AC-coupled or bidirectional signal lines.
What is the thermal resistance specification for P6KE82-E3/54?
The P6KE82-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured under standard test conditions. This parameter enables thermal modeling of the device when mounted on PCBs with copper pours or heatsinks. Its junction-to-ambient resistance (RθJA) is 75 °C/W, reflecting performance on a standard FR-4 test board without added copper area - critical for derating calculations in the P6KE82-E3/54's power dissipation profile.
