Product details
Overview
P6KE68C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal or power lines. It features a 68 V breakdown voltage (VBR), 600 W peak pulse power (10/1000 μs), 92 V maximum clamping voltage at 6.5 A, 1.0 μA max reverse leakage at 58.1 V, and DO-204AC (DO-15) package - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE68C-E3/54 datasheet, P6KE68C-E3/54 pinout, P6KE68C-E3/54 application, or P6KE68C-E3/54 equivalent, key selection criteria include bi-directional clamping capability, UL 497B recognition, AEC-Q101 qualification (HE3 variant), thermal resistance (RθJL = 20 °C/W), and compliance with 10/1000 μs surge waveform standards.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 GΩ at VWM), then rapidly avalanches below 1 ns to limit transient overvoltage. Its bi-directional symmetry enables use on AC-coupled or floating lines without polarity concerns.
Clamping performance is defined by VC = 92 V at IPPM = 6.5 A (10/1000 μs), with temperature coefficient of VBR = +0.104 %/°C - ensuring stable threshold across automotive (-40 °C to +125 °C operating range) and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 64.6 V / 71.4 V at 1.0 mA test current - defines precise avalanche onset window for reliable triggering |
| VWM | 58.1 V - maximum continuous working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 92 V at 6.5 A (10/1000 μs) - actual worst-case line voltage seen by protected IC during surge |
| PPPM | 600 W - peak transient energy absorption capacity per single event |
| IFSM | Not applicable - bi-directional type has no forward surge rating (only uni-directional devices specify IFSM) |
| TJ max. | +175 °C - junction temperature limit enabling operation in under-hood automotive locations |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with UL 94 V-0 molded epoxy |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy-molded case with no polarity marking (bi-directional). Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102; meets JESD 201 Class 1A whisker test (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | No functional distinction - either lead connects to protected line; clamps equally in both directions |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, low-noise avalanche behavior and long-term reliability under repetitive surges |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out with <5 nH trace inductance |
| UL 497B recognized (QVGQ2) | Validates suitability for telecom and industrial signal line protection without additional certification effort |
| AEC-Q101 qualified (HE3 variant) | Confirms robustness for automotive applications including engine control modules and body electronics |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns response), critical for protecting 3.3 V/5 V logic |
Applications
| Automotive Sensor Interface | Industrial RS-485 Bus Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in engine bay environments subject to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Shunt clamping element placed between signal line and ground, triggered within <1 ns to clamp transients to ≤92 V. Use Value: Prevents permanent damage to 12-bit ADC inputs and op-amp front-ends exposed to ±100 V/50 ms transients. |
Use Scenario: Safeguarding differential data lines in factory automation PLCs connected to long cable runs susceptible to lightning-induced surges. IC Role / Device Role / Timing Role: Bi-directional TVS placed across A/B lines and to ground, absorbing common-mode and differential-mode energy simultaneously. Use Value: Maintains bus integrity during 4 kV EFT bursts while preserving signal rise time (<10 ns degradation) due to low junction capacitance (~50 pF). |
| Consumer USB Port ESD Protection | Telecom DSL Line Surge Suppression |
Use Scenario: Secondary-level surge protection on upstream USB 2.0 VBUS and D+/D− lines in set-top boxes exposed to AC mains coupling. IC Role / Device Role / Timing Role: Coordinated clamping device working with primary polymer PTC and downstream ESD arrays to handle multi-stress events. Use Value: Limits let-through voltage to <92 V during 600 W surges, preventing latch-up in USB transceivers rated for 5.5 V absolute max. |
Use Scenario: Primary protection on twisted-pair DSL lines entering residential gateways, subjected to induced surges from nearby power lines. IC Role / Device Role / Timing Role: First-stage shunt suppressor mounted at line entry point, diverting >95 % of surge current before reaching transformer and PHY IC. Use Value: Enables compliance with GR-1089-CORE Zone 3 requirements (10/700 μs, 10 kV) via cascaded protection architecture. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | DO-214AA package, 64 V VBR, 600 W PPPM, lower VC = 103 V @ 5.8 A, higher IPPM | Surface-mount alternative requiring PCB rework; better suited for high-density layouts | Select SMBJ64CA when board space is constrained and SMT assembly is preferred over through-hole. |
| P6KE68A | Uni-directional version, identical VBR/VC/PPPM, cathode band marking, 3.5 V VF @ 50 A | Requires polarity-aware placement; only suitable for DC-biased lines with known ground reference | Choose P6KE68A only where circuit topology guarantees unidirectional surge direction and polarity stability. |
Compared with P6KE68C-E3/54, SMBJ64CA offers SMT compatibility but requires layout redesign, while P6KE68A sacrifices bi-directional flexibility for marginally lower forward voltage - neither is pin-compatible, but both serve overlapping surge suppression roles with distinct mechanical and biasing constraints.

FAQ
What does the "C" suffix indicate in P6KE68C-E3/54?
The "C" in P6KE68C-E3/54 denotes bi-directional configuration - meaning the device clamps voltage transients equally in both polarities, with no anode/cathode distinction. This is confirmed in Vishay's datasheet section "Devices for Bi-Direction Applications", where CA suffixes explicitly identify bi-directional types. The P6KE68C-E3/54 thus replaces two uni-directional devices in AC or floating-line protection schemes.
Is P6KE68C-E3/54 AEC-Q101 qualified?
No - P6KE68C-E3/54 carries the E3 suffix, indicating RoHS-compliant commercial grade. AEC-Q101 qualification applies only to the HE3 variant (e.g., P6KE68CHE3/54), which undergoes additional stress testing per automotive standard. Engineers selecting for automotive under-hood use must specify the HE3 version to ensure qualification compliance.
What is the maximum clamping voltage of P6KE68C-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE68C-E3/54 is 92 V, measured at 6.5 A peak pulse current using the standard 10/1000 μs waveform. This value is specified in the Electrical Characteristics table on page 2 of Vishay document 88369 and represents the worst-case voltage imposed on protected circuitry during a full-rated surge event.
Can P6KE68C-E3/54 be used in place of a uni-directional TVS like P6KE68A?
P6KE68C-E3/54 can replace P6KE68A only in circuits where polarity is undefined or alternating - such as AC signal lines, transformer-coupled interfaces, or floating grounds. It must not substitute P6KE68A in DC-biased applications with fixed polarity, as the absence of cathode marking prevents correct orientation and may compromise protection integrity.
What packaging format is supplied for P6KE68C-E3/54?
P6KE68C-E3/54 is supplied in 13-inch diameter paper tape and reel packaging, with a base quantity of 4000 units per reel (ordering code /54). Lead finish is matte tin, compliant with J-STD-002 and JESD 22-B102 solderability standards, and passes JESD 201 Class 1A whisker testing - suitable for both wave and selective solder processes.
