Product details
Overview
P6KE6.8A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of sensitive electronics. It features a 6.8 V breakdown voltage (VBR min 6.45 V, max 7.14 V at 10 mA), 5.8 V standoff voltage (VWM), clamps to ≤10.5 V at 57.1 A peak pulse current (10/1000 µs), and delivers 600 W peak pulse power in DO-15 package - deployed on power rails and I/O lines of automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P6KE6.8A-E3/54 datasheet, P6KE6.8A-E3/54 pinout, P6KE6.8A-E3/54 application, or P6KE6.8A-E3/54 equivalent, key selection criteria include its 10.5 V clamping voltage at rated surge, 1000 µA max reverse leakage at VWM, AEC-Q101 qualification status, DO-15 thermal resistance (RθJL = 20 °C/W), and unidirectional polarity with cathode band marking.
Technical Context
The P6KE6.8A-E3/54 operates as a silicon avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response to transients. Its clamping behavior is defined by a low incremental surge resistance and tightly specified VBR tolerance (±5% typical), enabling predictable protection coordination with downstream ICs such as microcontrollers and CAN transceivers.
It supports repetitive surge events at 0.01% duty cycle and withstands 100 A non-repetitive forward surge (8.3 ms half-sine). Thermal performance is characterized by RθJL = 20 °C/W and RθJA = 75 °C/W, with maximum junction temperature rated at +175 °C - suitable for under-hood automotive environments and industrial control cabinets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 5.8 V - maximum continuous reverse operating voltage before leakage exceeds 1000 µA |
| VC @ IPPM | ≤10.5 V at 57.1 A (10/1000 µs) - ensures protected circuit sees no more than 10.5 V during worst-case surge |
| PPPM | 600 W - peak transient energy absorption capacity without failure under standardized waveform |
| IFSM | 100 A (8.3 ms half-sine) - surge current handling for short-duration inductive switch-off events |
| TJ max | +175 °C - enables operation in high-temperature automotive and industrial ambient conditions |
| Package | DO-15 (DO-204AC) - industry-standard axial leaded package with UL 94 V-0 molded epoxy and matte tin leads |
Pinout & Package
DO-15 (DO-204AC) package: axial-leaded, cylindrical epoxy-molded body with cathode band marking on one end. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, rated for 275 °C dip soldering (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8A | DO-214AA package (SMB), 600 W rating, VBR = 6.45–7.14 V, VC = 11.2 V @ 53.5 A | Surface-mount footprint; lower thermal resistance (RθJA ≈ 40 °C/W) but requires PCB reflow vs. through-hole wave solder | Select SMBJ6.8A for space-constrained PCBs where automated assembly and higher power density are prioritized. |
| 1.5KE6.8A | Same DO-15 package, identical VBR/VC specs, but rated for 1500 W peak power (10/1000 µs) | Higher surge margin for infrequent but extreme transients (e.g., lightning-induced surges in outdoor telecom); larger junction capacitance (≈1500 pF) | Choose 1.5KE6.8A when legacy designs require drop-in replacement with enhanced surge headroom and board layout compatibility is critical. |
Compared with SMBJ6.8A and 1.5KE6.8A, the P6KE6.8A-E3/54 offers optimal balance of through-hole manufacturability, AEC-Q101 qualification, and cost-effective 600 W protection - making it preferred for automotive Tier 2 suppliers and industrial OEMs requiring validated reliability without over-spec'ing surge capacity.

FAQ
What is the clamping voltage of P6KE6.8A-E3/54 at its rated peak pulse current?
The P6KE6.8A-E3/54 clamps to a maximum of 10.5 V when subjected to its rated peak pulse current of 57.1 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and guarantees that downstream circuitry remains within safe operating voltage limits during transient events. The P6KE6.8A-E3/54 achieves this with a low clamping ratio of approximately 1.55 relative to its nominal breakdown voltage.
Is P6KE6.8A-E3/54 qualified for automotive applications?
Yes, the P6KE6.8A-E3/54 is AEC-Q101 qualified, as confirmed by Vishay's documentation (Note "(1) AEC-Q101 qualified" in the datasheet). This qualification validates its reliability for use in automotive powertrain, chassis, and body electronics - including environments with extended temperature cycling, vibration, and humidity exposure. The E3 suffix specifically denotes RoHS-compliant commercial grade with AEC-Q101 validation.
What does the "-E3/54" suffix mean in P6KE6.8A-E3/54?
The "-E3/54" suffix indicates two packaging attributes: "E3" denotes RoHS-compliant, commercial-grade construction meeting JESD 201 Class 1A whisker testing, while "/54" specifies the preferred package code for 13-inch diameter paper tape and reel delivery, with a base quantity of 4000 units per reel. This format is used for automated SMT placement and ensures consistent traceability and handling per Vishay's ordering conventions.
How does P6KE6.8A-E3/54 differ from bidirectional variants like P6KE6.8CA?
The P6KE6.8A-E3/54 is unidirectional, featuring a cathode band for polarity-sensitive placement and conducting only in reverse avalanche mode; it blocks forward current above ~3.5 V. In contrast, P6KE6.8CA is bidirectional, symmetrical in both directions, and lacks polarity marking - suited for AC-coupled or floating signal lines. The P6KE6.8A-E3/54 is selected when protecting DC rails referenced to ground, whereas P6KE6.8CA serves differential or AC applications.
What is the maximum reverse leakage current for P6KE6.8A-E3/54 at its standoff voltage?
The P6KE6.8A-E3/54 exhibits a maximum reverse leakage current (ID) of 1000 µA at its standoff voltage (VWM) of 5.8 V, measured at TA = 25 °C. This low leakage ensures minimal power loss and signal integrity impact in always-on circuits such as automotive always-live modules or industrial sensor bias networks. Leakage remains well below 10 µA at room temperature in typical operating conditions.
