Product details
Overview
P4KE82CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 400 W peak pulse power (10/1000 μs), 70.1 V standoff voltage (VWM), 77.9–86.1 V breakdown voltage (VBR at 1 mA), and 113 V maximum clamping voltage (VC at IPPM), with AEC-Q101 qualification for automotive use.
For engineers reviewing the P4KE82CAHE3/54 datasheet, P4KE82CAHE3/54 pinout, P4KE82CAHE3/54 application, or P4KE82CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 leaded package compatibility, 175 °C max junction temperature, low incremental surge resistance, and compliance with automotive reliability standards.
Technical Context
This device operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold, it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable VBR tolerance and fast response (<1 ns), while the bidirectional structure enables symmetric protection on AC-coupled or floating lines without polarity concerns.
The P4KE82CAHE3/54 sustains 400 W peak pulse power under 10/1000 μs waveform at 0.01% duty cycle, with thermal resistance RθJL = 66 °C/W enabling effective heat dissipation through leads. Its 1.5 W steady-state power rating and -55 °C to +175 °C operating range support deployment in harsh industrial and automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 70.1 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 77.9–86.1 V at 1 mA - Tight 5% tolerance window ensures predictable avalanche initiation across production lots |
| VC (Clamping Voltage) | 113 V at IPPM - Limits peak voltage seen by protected ICs during 400 W transient events |
| PPPM (Peak Pulse Power) | 400 W - Sustains high-energy surges per IEEE C62.41-compliant 10/1000 μs waveform |
| IPPM (Peak Pulse Current) | 3.5 A - Maximum surge current diverted during clamping; derived from VC and waveform shape |
| TJ max. | +175 °C - Enables operation in under-hood automotive or high-temperature industrial enclosures |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Identical electrical behavior in both directions; either lead may connect to line or ground |
| Lead 1 / Lead 2 | Thermal and mechanical interface | Primary heat conduction path to PCB copper; RθJL = 66 °C/W requires ≥10 mm lead length for rated derating |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85CA | DO-214AA package, 85 V VBR min, 100 W PPPM, lower clamping ratio but higher surge current rating (12.3 A) | Surface-mount layout; better suited for high-density PCBs where axial DO-41 leads are impractical | Select SMBJ85CA when board space is constrained and reflow compatibility is required; verify thermal pad design for 100 W dissipation |
| 1.5KE82CA | DO-201AD package, identical VBR/VWM/VC specs, 1500 W PPPM, higher IFSM (200 A), larger footprint and weight | Higher energy handling for industrial motor drives or power supply input stages requiring >400 W surge margin | Choose 1.5KE82CA for primary-side AC/DC input protection where 1500 W pulse rating justifies larger DO-201AD form factor |
Compared with SMBJ85CA and 1.5KE82CA, the P4KE82CAHE3/54 delivers optimal balance of AEC-Q101 qualification, DO-41 through-hole manufacturability, and 400 W surge capability-making it ideal for cost-sensitive, high-reliability automotive and industrial control applications where leaded assembly and proven field history are prioritized.

FAQ
What does the "CA" suffix indicate in P4KE82CAHE3/54?
The "CA" suffix in P4KE82CAHE3/54 denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both forward and reverse directions. This eliminates polarity concerns during PCB placement and enables protection of AC-coupled or floating signal lines without requiring orientation verification. The P4KE82CAHE3/54 has no color band or marking, consistent with all CA-suffix variants in the P4KE series.
Is P4KE82CAHE3/54 suitable for automotive applications?
Yes, P4KE82CAHE3/54 is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces. Its -55 °C to +175 °C operating range, glass-passivated junction, and DO-41 package with matte tin plating meet stringent automotive environmental and solderability requirements. The HE3 suffix specifically indicates AEC-Q101 qualification per Vishay's ordering nomenclature.
How does the clamping voltage of P4KE82CAHE3/54 compare to its breakdown voltage?
The P4KE82CAHE3/54 has a breakdown voltage (VBR) range of 77.9–86.1 V at 1 mA test current and a maximum clamping voltage (VC) of 113 V at its rated peak pulse current (IPPM = 3.5 A). This 31–46% clamping ratio reflects efficient energy diversion with minimal voltage overshoot, critical for protecting 75 V-rated downstream components such as CAN transceivers or industrial I/O drivers.
What is the significance of the "HE3/54" in P4KE82CAHE3/54?
In P4KE82CAHE3/54, "HE3" indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, while "/54" specifies the preferred packaging code: 5500-piece 13-inch paper tape and reel. This format ensures compatibility with automated pick-and-place equipment and guarantees traceable, automotive-grade material handling throughout the supply chain.
Can P4KE82CAHE3/54 replace unidirectional P4KE82A variants?
No, P4KE82CAHE3/54 cannot directly replace unidirectional P4KE82A devices because their electrical behavior differs fundamentally: the CA variant conducts in both directions above VBR, whereas the A variant only clamps in reverse bias. Substituting them without circuit review risks unintended forward conduction, altered bias conditions, or failure to suppress positive-going transients on grounded lines. Always validate polarity and signal topology before interchange.
