Designed to safeguard sensitive microelectronics and power lines from inductive load switching and lightning-induced voltage surges, this component features a glass-passivated chip junction that delivers a peak pulse power dissipation rating of 800W using a 10/1000µs test waveform (stacked-die configuration). It offers a reverse standoff voltage ($V_{R}$) of 58.1V, a minimum breakdown voltage ($V_{BR}$) of 64.6V (maximum 71.4V at a test current of 1mA), and a maximum clamping voltage ($V_C$) of 92.0V. Operating across a wide junction temperature range of -55°C to 175°C, the device maintains exceptional thermal stability with a typical junction-to-lead thermal resistance ($R_{\theta JL}$) of 20°C/W and a fast response time of less than 1.0 picosecond from 0V to breakdown minimum. This transient voltage suppressor is ideally suited for deployment in power conversion architectures, telecommunication infrastructure, industrial automation controls, and consumer electronics input/output (I/O) interfaces and VCC distribution buses. In typical application circuits, the P6KE68A is placed in parallel across the signal or power line to be protected, clamping overvoltage transients safely to ground while presenting minimal reverse leakage current under normal operating conditions. The through-hole DO-204AC package style facilitates secure mounting on printed circuit boards and is fully compatible with high-temperature lead-free reflow soldering processes up to 260°C for 30 seconds, adhering strictly to industry standards for environmental and reliability compliance. ## Specifications | Parameter | Value | |---|---| | Svhc | To Be Advised | | No. Of Pins | 2Pins | | Tvs Polarity | Unidirectional | | Product Range | P6KE Series | | Qualification | - | | Diode Mounting | Through Hole | | Diode Case Style | DO-15 (DO-204AC) | | Clamping Voltage Max | 92V | | Reverse Standoff Voltage | 58.1V | | Maximum Breakdown Voltage | 71.4V | | Minimum Breakdown Voltage | 64.6V | | Operating Temperature Max | 175°C | | Peak Pulse Power Dissipation | 800W | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:3930031/) **TVS Diodes** Axial Leaded – 600W > P6KE series |P6KE Series|||||**~~RoHS~~**
