Product details
Overview
P6KE68CHE3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 64.6 V minimum and 71.4 V maximum breakdown voltage at 1 mA test current, 58.1 V stand-off voltage, and clamps to ≤92.0 V at 6.5 A peak pulse current. It is AEC-Q101 qualified and used in automotive sensor line protection.
For engineers reviewing the P6KE68CHE3/54 datasheet, P6KE68CHE3/54 pinout, P6KE68CHE3/54 application, or P6KE68CHE3/54 equivalent, key selection criteria include bi-directional clamping capability, UL 497B recognition, RoHS-compliant HE3 whisker-tested leads, and thermal resistance of 20 °C/W junction-to-lead - critical for high-reliability transient suppression in constrained PCB layouts.
Technical Context
This device operates as a voltage-clamped shunt protector with symmetrical avalanche breakdown in both polarities, enabling use on AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage (<1.0 μA at 58.1 V) and fast response time (<1.0 ns), while low incremental surge resistance supports effective energy diversion during ESD or lightning-induced surges.
The P6KE68CHE3/54 is rated for -55 °C to +175 °C operating junction temperature and exhibits a 0.104 %/°C temperature coefficient of breakdown voltage. Its 20 °C/W junction-to-lead thermal resistance enables direct solder-mount thermal management without heatsinking under typical 600 W pulse conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 64.6 V min / 71.4 V max at 1 mA - defines precise clamping onset threshold for overvoltage events |
| Stand-off Voltage (VWM) | 58.1 V - maximum continuous working voltage before leakage exceeds 1.0 μA |
| Peak Pulse Power (PPPM) | 600 W (10/1000 μs waveform) - determines survivability against IEC 61000-4-5 Level 4 surges |
| Clamping Voltage (VC) | ≤92.0 V at 6.5 A IPPM - limits downstream voltage stress during worst-case transient |
| Junction Temperature Range | -55 °C to +175 °C - supports operation in under-hood automotive and industrial environments |
| Thermal Resistance (RθJL) | 20 °C/W - enables reliable power dissipation through PCB copper without external heatsink |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability; HE3 suffix indicates JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (bi-directional) | Reversible avalanche terminals | No polarity marking; symmetric conduction enables placement on AC or differential lines without orientation check |
| Lead 1 / Lead 2 | Current path interface | Both leads serve identical roles - no functional distinction; thermal path optimized via 20 °C/W RθJL |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | DO-214AA package; 64 V nominal VBR; 600 W rating; lower RθJA (50 °C/W vs. 75 °C/W) | Better suited for surface-mount designs with limited board space; requires reflow-compatible layout | Select SMBJ64CA when migrating from through-hole to SMT or when higher power density is required. |
| 1.5KE68CA | Same DO-204AC package; 68 V nominal VBR; 1500 W peak power; larger physical size and higher IPPM (18.3 A) | Used where higher surge margin is needed (e.g., AC mains input stages), but with increased board area and cost | Choose 1.5KE68CA only if system-level testing confirms need for >600 W surge handling beyond P6KE68CHE3/54 capability. |
Compared with SMBJ64CA and 1.5KE68CA, the P6KE68CHE3/54 offers optimal balance of AEC-Q101 qualification, axial-leaded ease-of-handling, and verified 600 W performance in cost-sensitive automotive and industrial applications - making it preferred for through-hole production and legacy design refreshes.

FAQ
What does the 'HE3' suffix indicate in P6KE68CHE3/54?
The 'HE3' suffix in P6KE68CHE3/54 denotes RoHS-compliant construction with JESD 201 Class 2 whisker resistance and AEC-Q101 qualification. It confirms that the device meets automotive reliability standards and uses matte tin-plated leads tested for long-term intermetallic stability - a critical requirement for P6KE68CHE3/54 deployment in engine control and ADAS systems.
Is P6KE68CHE3/54 unidirectional or bidirectional?
P6KE68CHE3/54 is a bi-directional TVS diode, as indicated by the 'CA' designation embedded in its full part number structure (P6KE68C = bi-directional). It provides symmetrical clamping for both positive and negative transients, eliminating polarity concerns during placement - a key advantage of P6KE68CHE3/54 in AC-coupled or floating signal line protection.
What is the maximum clamping voltage for P6KE68CHE3/54 at rated peak pulse current?
The maximum clamping voltage (VC) for P6KE68CHE3/54 is 92.0 V at 6.5 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Vishay specification 88369 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events - a core parameter for validating P6KE68CHE3/54 system-level surge immunity.
Can P6KE68CHE3/54 be used in place of P6KE68A?
No - P6KE68CHE3/54 is bi-directional (P6KE68C), whereas P6KE68A is unidirectional. Their VBR, VWM, and clamping characteristics differ: P6KE68A has VF = 3.5 V and IFSM = 100 A, while P6KE68CHE3/54 has no forward voltage spec and is not rated for forward surge. Substituting P6KE68CHE3/54 for P6KE68A would compromise circuit functionality in DC-biased applications.
What is the thermal resistance from junction to lead for P6KE68CHE3/54?
The typical thermal resistance from junction to lead (RθJL) for P6KE68CHE3/54 is 20 °C/W, as specified in Vishay document 88369. This low value enables efficient heat transfer from the silicon die to the PCB copper through the axial leads, supporting reliable operation at full 600 W pulse ratings without additional heatsinking - a defining thermal characteristic of P6KE68CHE3/54 in high-power transient suppression roles.
