Product details
Overview
P6KE8.2CHE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection on DC power rails and signal lines. It features a 6.45 V minimum breakdown voltage (VBR), 7.02 V maximum stand-off 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 body electronics, industrial sensor interfaces, and consumer power supply inputs.
For engineers reviewing the P6KE8.2CHE3/54 datasheet, P6KE8.2CHE3/54 pinout, P6KE8.2CHE3/54 application, or P6KE8.2CHE3/54 equivalent, key selection criteria include verified clamping performance under 50 A surge, AEC-Q101 qualification status, DO-204AC (DO-15) package compatibility, and thermal resistance (RθJL = 20 °C/W) for lead-mounted thermal management.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds VWM (7.02 V), it transitions from high-impedance blocking to low-impedance conduction within <1 ns, diverting transient energy to ground. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low leakage (<200 µA at VWM).
Designed for single-pulse and low-duty-cycle repetitive transients, it sustains 100 A non-repetitive forward surge (IFSM) and maintains clamping integrity up to TJ = 175 °C. The 20 °C/W junction-to-lead thermal resistance enables direct PCB trace heat sinking without auxiliary heatsinks in moderate-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA test current - defines precise turn-on threshold for reliable overvoltage detection |
| VWM | 7.02 V - maximum continuous reverse operating voltage before leakage exceeds 200 µA |
| VC @ IPPM | 12.1 V at 49.6 A (10/1000 µs) - limits protected circuit voltage during worst-case surge |
| PPPM | 600 W - peak transient power handling capacity without degradation |
| RθJL | 20 °C/W - enables thermal design using PCB copper as heatsink via leads |
| TJ max. | 175 °C - supports operation in under-hood automotive and industrial ambient environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package

Applications
| Automotive Body Control Module | Industrial Sensor Signal Line |
|---|---|
Use Scenario: Protects LIN bus transceivers and microcontroller I/O from load dump and inductive switching spikes in door modules and seat controllers.

Use Scenario: Protects vehicle ECU diagnostic interface pins from ESD and battery connection reversal events during service. IC Role / Device Role: Bi-directional-capable variant not used here; P6KE8.2CHE3/54 serves as uni-directional clamp on VBAT-to-ground path. Use Value: Withstands ±15 kV contact ESD per IEC 61000-4-2 and clamps battery dump spikes to safe levels for CAN transceiver power rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | DO-214AA package; 8.0 V VWM, 12.0 V VC @ 49.2 A; same 600 W rating but higher thermal resistance (RθJA = 40 °C/W) | Surface-mount layout; requires reflow-compatible PCB design and lacks axial lead mechanical robustness | Select when board space is constrained and automated assembly is required |
| 1.5KE8.2A | Same DO-204AC package; identical VBR/VWM/VC specs but not AEC-Q101 qualified; 1.5 kW rating (over-specified for most 600 W needs) | Commercial-grade only; unsuitable for automotive production without additional qualification testing | Select for cost-sensitive industrial power supplies where automotive qualification is unnecessary |
Compared with SMBJ8.0A and 1.5KE8.2A, P6KE8.2CHE3/54 uniquely combines AEC-Q101 qualification, DO-204AC axial package for manual repairability and vibration resistance, and optimized thermal performance (RθJL = 20 °C/W) for lead-mounted heat dissipation - making it preferred for automotive and ruggedized industrial deployments.

FAQ
What is the clamping voltage of P6KE8.2CHE3/54 and how is it measured?
The clamping voltage (VC) of P6KE8.2CHE3/54 is 12.1 V, measured at 49.6 A peak pulse current using the standardized 10/1000 µs double-exponential waveform per IEC 61000-4-5. This value represents the maximum voltage seen across the device terminals during surge conduction and is critical for ensuring downstream ICs remain within absolute maximum ratings. P6KE8.2CHE3/54 achieves this clamping level while maintaining low dynamic impedance under transient conditions.
Is P6KE8.2CHE3/54 suitable for automotive applications?
Yes, P6KE8.2CHE3/54 is AEC-Q101 qualified and specifically rated for automotive use, including body electronics, lighting control, and infotainment power rails. Its 175 °C maximum junction temperature, glass-passivated junction, and validation across temperature cycling, HTRB, and mechanical shock ensure reliability in under-hood and cabin environments. P6KE8.2CHE3/54 meets the surge immunity requirements of ISO 7637-2 and complements automotive-grade power management ICs.
What does the "HE3/54" suffix mean in P6KE8.2CHE3/54?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "54" denotes the preferred package code for 13-inch paper tape and reel packaging with 4000 units per reel. This distinguishes P6KE8.2CHE3/54 from commercial-grade variants (e.g., E3 suffix) and confirms its suitability for automotive production. P6KE8.2CHE3/54 is supplied in tape-and-reel format optimized for SMT placement and manual insertion workflows.
How does P6KE8.2CHE3/54 compare to bi-directional TVS diodes like P6KE8.2CA?
P6KE8.2CHE3/54 is uni-directional and features a cathode band for polarity-sensitive placement, whereas P6KE8.2CA is bi-directional with no polarity marking and symmetric clamping in both directions. P6KE8.2CHE3/54 offers tighter VBR tolerance (±5 % vs. ±6 % for CA types) and is preferred for DC rail protection where reverse voltage is not expected. P6KE8.2CHE3/54 also carries AEC-Q101 qualification, unlike many CA variants, making it more suitable for automotive power domains.
What is the thermal resistance and how does it affect PCB layout for P6KE8.2CHE3/54?
P6KE8.2CHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, meaning each watt dissipated raises the junction temperature 20 °C above the lead temperature. This allows effective heat transfer through axial leads into wide PCB copper pours - eliminating need for dedicated heatsinks. For optimal thermal performance, P6KE8.2CHE3/54 should be mounted with ≥5 mm lead length and connected to ≥25 mm² copper area per lead. Layout directly impacts sustained surge capability and long-term reliability.
