Product details
Overview
P6KE82A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 77.9 V minimum breakdown voltage (VBR), 70.1 V maximum standoff voltage (VWM), 113 V clamping voltage at 5.3 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the P6KE82A-E3/54 datasheet, P6KE82A-E3/54 pinout, P6KE82A-E3/54 application, or P6KE82A-E3/54 equivalent, key selection criteria include verified clamping performance under 5.3 A surge, thermal resistance (RθJL = 20 °C/W), unidirectional polarity marking, AEC-Q101 qualification status, and DO-15 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This device operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (70.1 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and fast response time (<1 ns), critical for protecting MOSFET gate drivers and microcontroller I/O pins against ESD and inductive switching spikes.
Thermal design relies on lead-to-case conduction: RθJL = 20 °C/W enables 5.0 W steady-state dissipation at TL = 75 °C, while derating curves confirm usable surge capability down to TA = 125 °C. The 100 A IFSM rating supports single-event lightning surge immunity per IEC 61000-4-5 (line-to-ground).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 70.1 V maximum - defines highest continuous DC operating voltage before leakage exceeds 1 μA |
| VBR @ IT = 1 mA | 77.9–86.1 V - ensures reliable avalanche initiation within ±5 % tolerance at test current |
| VC @ IPPM = 5.3 A | 113 V maximum - limits protected node voltage during worst-case 600 W transient event |
| PPPM | 600 W - sustains 10/1000 μs surge without degradation, validated per Fig. 1 derating curve |
| RθJL | 20 °C/W - enables thermal management via PCB copper pour or heatsinked leads |
| IFSM | 100 A - withstands 8.3 ms half-sine surge (IEC 61000-4-5 Level 4) |
| TJ max. | +175 °C - supports operation in under-hood automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85A | DO-214AA package, 85 V VBR min., 100 W lower PPPM (500 W), RθJA = 40 °C/W | Suitable for space-constrained SMT designs but requires thermal pad for same power handling | Select SMBJ85A only when board real estate mandates SMT and thermal vias support 500 W surge |
| 1.5KE82A | Same DO-15 package, identical VBR/VWM/VC, but 1.5 kW PPPM and 200 A IFSM; larger die, higher cost | Used where IEC 61000-4-5 Level 5 (4 kV line-earth) compliance is mandatory | Choose 1.5KE82A only if system-level surge testing requires >600 W margin or higher IFSM |
Compared with SMBJ85A and 1.5KE82A, P6KE82A-E3/54 delivers optimal balance of proven AEC-Q101 reliability, 600 W surge capacity in legacy through-hole form factor, and cost efficiency for volume automotive and industrial applications - without over-specifying power or sacrificing thermal performance in standard leaded layouts.

FAQ
What is the maximum clamping voltage of the P6KE82A-E3/54 under specified surge conditions?
The P6KE82A-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 standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88369 and defines the upper voltage limit imposed on protected circuitry during transient events. The P6KE82A-E3/54 maintains this clamping performance across its full operating temperature range.
Is the P6KE82A-E3/54 suitable for automotive applications?
Yes, the P6KE82A-E3/54 is AEC-Q101 qualified (E3 suffix denotes commercial grade with AEC-Q101 compliance), making it suitable for automotive applications including engine control units, body electronics, and infotainment power supplies. Its 175 °C maximum junction temperature, robust surge ratings, and glass-passivated junction meet automotive environmental and reliability requirements. The P6KE82A-E3/54 is explicitly listed in Vishay's AEC-Q101 qualified product table.
What does the "-E3/54" suffix indicate in P6KE82A-E3/54?
The "-E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance. The "/54" denotes the preferred package code for 13-inch paper tape and reel packaging containing 4000 units. This ordering code ensures traceable, factory-standard packaging for automated assembly. The P6KE82A-E3/54 is shipped in this configuration by Vishay.
How does the P6KE82A-E3/54 compare to bidirectional TVS diodes like P6KE82CA?
The P6KE82A-E3/54 is unidirectional and features a cathode band for polarity identification, whereas P6KE82CA is bidirectional with no polarity marking and symmetric clamping in both directions. The P6KE82A-E3/54 offers lower leakage at VWM (1 μA vs. 2 μA for CA types above 10 V) and is intended for DC rail protection where reverse conduction must be blocked. Use P6KE82A-E3/54 when protecting polarized circuits such as MOSFET gates or LDO inputs.
What is the thermal resistance from junction to lead (RθJL) for the P6KE82A-E3/54?
The P6KE82A-E3/54 has a typical thermal resistance from junction to lead (RθJL) of 20 °C/W, as specified in the Thermal Characteristics section of Vishay document 88369. This parameter enables accurate thermal modeling when mounting the device on PCBs with copper pours or heatsinked leads. The P6KE82A-E3/54 achieves 5.0 W steady-state power dissipation at TL = 75 °C, supporting reliable operation in thermally demanding environments.
