Product details
Overview
P6KE8.2-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 7.79 V minimum breakdown voltage (VBR), 7.02 V maximum standoff voltage (VWM), 12.1 V clamping voltage (VC) at 49.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6KE8.2-E3/54 datasheet, P6KE8.2-E3/54 pinout, P6KE8.2-E3/54 application, or P6KE8.2-E3/54 equivalent, key selection criteria include verified clamping performance under 50 A surge, DO-204AC (DO-15) package compatibility with through-hole PCB layouts, unidirectional polarity marking, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a silicon avalanche diode optimized for fast transient suppression. Its glass-passivated junction delivers sub-nanosecond response time and low incremental surge resistance, enabling effective clamping of ESD, inductive switching spikes, and lightning-induced surges before downstream ICs experience overstress.
The P6KE8.2-E3/54 is rated for 175 °C maximum junction temperature and exhibits a +0.065 %/°C temperature coefficient of VBR. It supports 100 A non-repetitive forward surge current (IFSM) and maintains ≤1000 µA reverse leakage at 7.02 V, ensuring minimal standby power loss in always-on circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V at 10 mA test current - defines reliable avalanche initiation threshold across production lot and temperature range |
| VWM | 7.02 V - maximum continuous reverse operating voltage before leakage exceeds 200 µA, sets safe DC rail margin |
| VC @ IPPM | 12.1 V at 49.6 A - clamped voltage during 10/1000 µs transient, determines protected circuit's maximum stress level |
| PPPM | 600 W - peak pulse power handling capability, enables robust protection against IEC 61000-4-5 Level 4 surges |
| IFSM | 100 A - 8.3 ms half-sine surge current rating, supports protection of 12 V automotive power inputs |
| TJ max. | 175 °C - extended thermal operating limit allows use in under-hood or high-ambient industrial enclosures |
| Package | DO-204AC (DO-15) - axial-leaded through-hole package with matte tin-plated leads, UL 94 V-0 molded epoxy body |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy-molded case with cathode band marking on one end. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102. Maximum solder dip: 275 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode (banded end) | Avalanche clamping terminal | Connected to protected line (e.g., 5 V rail or CAN_H); conducts when line voltage exceeds VWM |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repetitive surge stress |
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 4 kV surge immunity without derating in standard PCB layouts |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive applications including engine control units and body electronics modules |
| Low clamping ratio (VC/VBR ≈ 1.55) | Minimizes overvoltage exposure to protected ICs such as microcontrollers and transceivers |
| UL 94 V-0 flammability rating | Ensures flame-retardant behavior during catastrophic failure modes in safety-critical systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | DO-214AA package (SMB), 8.0 V VWM, 12.0 V VC @ 49.2 A, same 600 W rating | Surface-mount alternative; requires PCB re-layout; lower thermal resistance (RθJA = 50 °C/W vs. 75 °C/W) | Select SMBJ8.0A for space-constrained SMT designs where board area is prioritized over through-hole serviceability. |
| 1.5KE8.2A | Same DO-204AC package, identical VBR/VWM/VC specs, but rated for 1500 W peak power (10/1000 µs) | Higher-power variant; larger junction area; higher IFSM (200 A) and thermal mass | Choose 1.5KE8.2A when system-level surge testing exceeds IEC 61000-4-5 Level 4 or requires extended duty-cycle resilience. |
Compared with SMBJ8.0A and 1.5KE8.2A, the P6KE8.2-E3/54 offers optimal balance of cost, proven automotive qualification (AEC-Q101), and through-hole manufacturability - making it preferred for medium-volume industrial controls and legacy automotive modules where layout flexibility and supply chain stability are critical.

FAQ
What is the polarity configuration of the P6KE8.2-E3/54?
The P6KE8.2-E3/54 is a unidirectional TVS diode. Its cathode is marked by a color band on the DO-204AC package body. This configuration allows it to conduct only during positive transients on the cathode-connected line relative to anode (ground), making it ideal for DC rail protection where reverse voltage blocking is required.
Does the P6KE8.2-E3/54 meet AEC-Q101 requirements?
Yes, the P6KE8.2-E3/54 is AEC-Q101 qualified. The "E3" suffix indicates RoHS-compliant commercial grade with AEC-Q101 qualification, validated per stress tests including HTGB, HTRB, TCT, and surge endurance - confirming suitability for automotive powertrain and chassis applications.
What is the maximum clamping voltage of the P6KE8.2-E3/54 under surge conditions?
The P6KE8.2-E3/54 has a maximum clamping voltage (VC) of 12.1 V at 49.6 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is guaranteed across temperature and production lot, defining the upper voltage limit imposed on protected circuitry during standardized surge events.
Can the P6KE8.2-E3/54 be used in bi-directional protection applications?
No - the P6KE8.2-E3/54 is strictly unidirectional. For bi-directional protection, Vishay specifies part numbers with "CA" suffix (e.g., P6KE8.2CA). Using the P6KE8.2-E3/54 in AC or dual-polarity signal paths would result in unintended forward conduction and failure.
What is the thermal resistance specification for the P6KE8.2-E3/54?
The P6KE8.2-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" lead length and define safe power derating above 25 °C ambient per Figure 5 in the datasheet.
