Product details
Overview
P4KE82A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features 77.9 V to 86.1 V breakdown voltage (VBR), 70.1 V maximum stand-off voltage (VWM), 113 A peak pulse current (IPPM), 400 W peak pulse power (10/1000 μs), and operates across -55 °C to +175 °C junction temperature range - used in automotive ECU protection and industrial sensor interface circuits.
For engineers reviewing the P4KE82A-E3/54 datasheet, P4KE82A-E3/54 pinout, P4KE82A-E3/54 application, or P4KE82A-E3/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance at rated surge current, RoHS-compliant packaging details, and AEC-Q101 qualification status for automotive-grade design validation.
Technical Context
The P4KE82A-E3/54 uses a glass passivated PN junction optimized for fast transient response (<1 ps typical) and low incremental surge resistance. Its unidirectional polarity enables cathode-referenced clamping with a marked band, and it complies with IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) immunity requirements when applied with proper PCB layout.
Thermal performance is defined by RθJL = 66 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, LLead = 10 mm). Derating begins above TA = 25 °C per Figure 2, and peak power capability drops to 50% at TJ = 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 77.9 V / 86.1 V at 1.0 mA test current - defines reliable conduction onset under surge conditions |
| VWM | 70.1 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 113 V clamping voltage at 113 A peak pulse current - limits downstream voltage stress during 10/1000 μs transients |
| PPPM | 400 W - peak pulse power handling with 0.01% duty cycle, enabling robust protection against repetitive surges |
| IFSM | 40 A - non-repetitive forward surge rating (8.3 ms half-sine), supports inrush current tolerance in DC power rails |
| TJ max. | +175 °C - high-temperature operation suitable for under-hood automotive and industrial environments |
| Package | DO-41 (DO-204AL) - axial-leaded, UL 94 V-0 molded epoxy case with matte tin-plated leads |
Pinout & Package
DO-41 (DO-204AL) package: axial leaded, cylindrical epoxy body with cathode band marking. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102; qualified to JESD 201 Class 1A whisker test (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts during positive transients when cathode is biased higher |
| Cathode | Clamping reference terminal | Marked end (band); tied to system ground or rail being protected; defines clamping threshold relative to this node |
Key Features

| Low clamping ratio (VC/VBR ≈ 1.31) | Minimizes overvoltage margin between clamping and device breakdown - critical for protecting 75 V-rated MOSFETs |
| RoHS-compliant, commercial grade | Meets EU Directive 2011/65/EU; no exemptions required; compatible with lead-free reflow and wave soldering processes |
Applications
| Automotive Engine Control Unit (ECU) | Industrial PLC Digital Input Module |
|---|---|
Use Scenario: Protection of 12 V/24 V supply inputs against load dump and alternator ripple transients. IC Role / Device Role: Primary overvoltage clamp placed upstream of DC-DC converters and microcontroller power rails. Use Value: Clamps 113 V surges at 113 A while maintaining <1.0 μA leakage at 70.1 V - prevents brownout and latch-up in safety-critical ECUs. |
Use Scenario: Shielding 24 V digital input channels from field-wiring induced switching transients in factory automation. IC Role / Device Role: Unidirectional TVS on each optocoupler input leg to suppress inductive kickback from solenoid drivers. Use Value: 77.9–86.1 V VBR aligns with 24 V system derating margins; DO-41 axial form factor allows through-hole mounting on ruggedized backplanes. |
| Telecom Power Supply Front-End | Consumer Appliance Motor Driver Board |
Use Scenario: Secondary-side transient suppression on +48 V telecom rectifier outputs feeding PoE injectors. IC Role / Device Role: Standoff-clamp element parallel to bulk capacitor to limit voltage overshoot during hot-swap events. Use Value: 400 W pulse rating handles repeated 10/1000 μs surges up to 100×/hour; 175 °C TJ max ensures stability in sealed enclosures. |
Use Scenario: Protection of gate driver ICs from Miller-induced spikes during BLDC motor commutation. IC Role / Device Role: Cathode-to-ground TVS on high-side FET source node to clamp negative-going transients below -0.7 V. Use Value: Fast response time and low VF (3.5 V @ 25 A) prevent false triggering while limiting dv/dt stress on isolated gate drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ80A | DO-214AA package; 80 V VWM, 125 A IPPM, 600 W PPPM; surface-mount only | Requires PCB redesign for SMD placement; better suited for high-density power supplies | Select SMBJ80A when board space is constrained and automated assembly is preferred over through-hole. |
| 1.5KE82A | Same DO-41 package; 82 V VBR range (77.9–86.1 V), but 1500 W PPPM and 125 A IPPM; higher surge capacity | Higher energy handling suits infrequent but severe lightning-induced surges in outdoor equipment | Choose 1.5KE82A where single-event surge energy exceeds 400 W capability - e.g., AC mains-connected interfaces. |
Compared with SMBJ80A and 1.5KE82A, the P4KE82A-E3/54 offers optimal balance of proven automotive qualification, axial-leaded serviceability, and 400 W surge rating for cost-sensitive 24 V/48 V industrial and automotive subsystems - without requiring layout changes or sacrificing AEC-Q101 compliance.

FAQ
What is the breakdown voltage tolerance of the P4KE82A-E3/54?
The P4KE82A-E3/54 has a specified breakdown voltage range of 77.9 V to 86.1 V at 1.0 mA test current, representing ±5.3% tolerance about the nominal 82 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports precise overvoltage margining in 75 V–85 V system designs where the P4KE82A-E3/54 is deployed.
Is the P4KE82A-E3/54 suitable for automotive applications?
Yes, the P4KE82A-E3/54 is AEC-Q101 qualified per the Vishay datasheet (Document Number: 88365, Revision: 16-Sep-2021), confirming its reliability for automotive use cases including engine control units, body control modules, and ADAS sensor interfaces. The P4KE82A-E3/54 meets stress test requirements for temperature cycling, humidity, and mechanical shock - making it appropriate for under-hood and cabin-mounted systems.
What is the clamping voltage of the P4KE82A-E3/54 at its rated peak pulse current?
The P4KE82A-E3/54 clamps to a maximum of 113 V at its rated peak pulse current of 113 A (10/1000 μs waveform). This VC value is measured under standardized surge conditions and defines the upper voltage limit imposed on protected circuitry - critical for ensuring downstream components like 100 V MOSFETs or 120 V capacitors remain within safe operating area during transient events involving the P4KE82A-E3/54.
Does the P4KE82A-E3/54 have bidirectional capability?
No, the P4KE82A-E3/54 is a unidirectional TVS diode, indicated by the "A" suffix (as opposed to "CA" for bidirectional types). It conducts only when the cathode is positive relative to the anode, and features a visible cathode band for polarity identification. For bidirectional protection, engineers must select a part such as P4KE82CA - the P4KE82A-E3/54 is not interchangeable in symmetrical AC or data-line applications.
What packaging format is used for the P4KE82A-E3/54?
The P4KE82A-E3/54 is supplied in 13-inch diameter paper tape and reel packaging, with a base quantity of 5500 pieces per reel (ordering code /54). The "E3" suffix confirms RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance - ensuring compatibility with both manual and automated through-hole assembly processes for the P4KE82A-E3/54.
