Product details
Overview
P6KE6.8CHE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 6.8 V breakdown voltage (VBR min = 6.45 V), 5.8 V stand-off voltage (VWM), 10.5 V clamping voltage at 57.1 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification - used in automotive sensor interface protection and industrial I/O circuitry.
For engineers reviewing the P6KE6.8CHE3/54 datasheet, P6KE6.8CHE3/54 pinout, P6KE6.8CHE3/54 application, or P6KE6.8CHE3/54 equivalent, this device delivers verified clamping performance under repetitive surge conditions, supports lead-free reflow and wave soldering per J-STD-002/JESD 22-B102, and provides traceable RoHS-compliant sourcing with HE3 whisker-tested terminations.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to transient events such as ESD, inductive switching spikes, and lightning-induced surges. Its uni-directional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
Thermal design relies on low junction-to-lead resistance (RθJL = 20 °C/W) and derating above 25 °C ambient, with maximum junction temperature rated at +175 °C. The DO-204AC (DO-15) package supports manual and automated assembly while maintaining UL 94 V-0 flammability compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA test current - defines precise avalanche initiation window for reliable turn-on without premature conduction |
| VWM | 5.8 V - maximum continuous reverse operating voltage before leakage exceeds 1000 µA, ensuring no false triggering in 5 V systems |
| VC @ IPPM | 10.5 V at 57.1 A (10/1000 µs) - clamping voltage limits downstream IC stress to safe levels during surge events |
| PPPM | 600 W - peak pulse power handling capability enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) |
| IFSM | 100 A (8.3 ms half-sine) - surge current rating supports protection of MOSFET gates and microcontroller I/O pins against load dump |
| TJ max | +175 °C - high junction temperature rating allows operation in under-hood automotive environments and sealed industrial enclosures |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with 0.432 g unit weight, compatible with through-hole and selective solder processes |
Pinout & Package
DO-204AC (DO-15) molded epoxy package with matte tin-plated leads; cathode indicated by color band on body end. Leads conform to J-STD-002 and JESD 22-B102 solderability standards. HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient 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, but lower IPPM (64.2 A) and higher VC (11.2 V) | Suitable for surface-mount designs; less effective clamping margin in space-constrained 5 V rail protection | Select SMBJ6.8A only when board real estate requires SMT and thermal coupling to copper pour compensates for higher RθJA |
| 1.5KE6.8A | Same DO-204AC package, identical VBR/VC, but 1500 W peak power (10/1000 µs) and higher IPPM (143 A) | Overqualified for most 5 V applications; larger junction capacitance may affect high-speed signal integrity | Choose 1.5KE6.8A only when legacy 1.5 kW surge testing (IEC 61000-4-5 Level 5) is mandated and layout permits higher energy dissipation |
Compared with SMBJ6.8A and 1.5KE6.8A, P6KE6.8CHE3/54 offers optimal balance of clamping precision (10.5 V), AEC-Q101 qualification, and DO-15 manufacturability - making it preferred for cost-sensitive, high-volume automotive and industrial through-hole designs requiring validated reliability.

FAQ
What is the clamping voltage of P6KE6.8CHE3/54 at its rated peak pulse current?
The P6KE6.8CHE3/54 has a maximum clamping voltage (VC) of 10.5 V at 57.1 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and ensures predictable voltage limiting during surge events. The P6KE6.8CHE3/54 maintains this clamping performance across its full operating temperature range (–55 °C to +175 °C) with minimal variation due to its stable avalanche junction.
Is P6KE6.8CHE3/54 suitable for automotive applications?
Yes, P6KE6.8CHE3/54 is AEC-Q101 qualified (denoted by the HE3 suffix), making it suitable for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces. Its DO-204AC package withstands mechanical vibration and thermal cycling, and its 175 °C maximum junction temperature supports under-hood deployment. The P6KE6.8CHE3/54 meets ISO 7637-2 Pulse 5a requirements when properly mounted with adequate trace width and grounding.
How does the P6KE6.8CHE3/54 differ from the P6KE6.8A-E3/54 variant?
The P6KE6.8CHE3/54 differs from P6KE6.8A-E3/54 solely in qualification level: the "H" in HE3 indicates AEC-Q101 qualification, while E3 denotes commercial-grade RoHS compliance only. Both share identical electrical parameters (VBR, VC, PPPM), DO-204AC package, and thermal characteristics. The P6KE6.8CHE3/54 undergoes additional stress testing per AEC-Q101, including HTGB, HTRB, and temperature cycling, confirming suitability for automotive use cases where P6KE6.8A-E3/54 would not be approved.
What is the maximum reverse leakage current for P6KE6.8CHE3/54 at its stand-off voltage?
The P6KE6.8CHE3/54 exhibits a maximum reverse leakage current (ID) of 1000 µA at its stand-off voltage (VWM) of 5.8 V, measured at 25 °C ambient. This low leakage ensures minimal power loss in always-on circuits and avoids false triggering in battery-powered systems. Leakage remains below 50 µA at 25 °C when operated at 5.0 V - well within typical 5 V rail tolerances - confirming stable blocking behavior prior to avalanche onset.
Can P6KE6.8CHE3/54 be used in bi-directional protection circuits?
No, P6KE6.8CHE3/54 is a uni-directional TVS diode and is not suitable for bi-directional protection. Its cathode marking and asymmetric IV curve require correct polarity orientation relative to the protected line. For bi-directional applications (e.g., AC lines or differential data buses), Vishay specifies CA-suffix variants like P6KE6.8CA. Using P6KE6.8CHE3/54 in reverse-biased configurations risks permanent failure due to forward conduction beyond its 100 A IFSM rating. Always verify polarity during PCB layout for P6KE6.8CHE3/54.
