600 Watt 6.8-440V Transient Voltage Suppressors TVS Diode P6KE6.8A to P6KE440A

Our P6KE diodes deliver a peak pulse power of 600W (10/1000μs waveform) and a peak surge current of 100A, fully meeting the surge protection requirements of most commercial and industrial circuits. With a response time of less than 1.0ps, it can quickly clamp overvoltages to protect sensitive components. The glass-passivated structure ensures ultra-low leakage current (<1μA for VBR>13V) and stable operation in a wide temperature range (-55°C to +175°C), eliminating the risk of abnormal circuit operation caused by protection devices.

We offer both unidirectional (P6KExxA) and bidirectional (P6KExxCA) models to adapt to DC circuits, AC circuits and polarity-unknown signal lines. We have a complete range of voltage ratings, which can be perfectly matched to 5V, 12V, 24V and other common working voltages in your design, avoiding the problem of mismatched protection voltage and ensuring normal operation of the circuit under normal conditions.

Every P6KE diode is produced in accordance with standardized production processes and undergoes 100% functional testing before leaving the factory. We strictly control the clamping voltage (VC) and breakdown voltage (VBR) to ensure that the product performance is consistent with the datasheet, reducing the risk of product failure in mass production and saving your after-sales maintenance costs.

Our technical team has rich experience in circuit protection design. We can help you select the most suitable P6KE model based on your circuit parameters, transient energy calculation and application environment. We provide free samples, detailed technical datasheets and application notes, and can respond to your technical questions and customization needs in a timely manner, accelerating your product development and project progress.

A: The unidirectional model (P6KExxA) is suitable for DC circuits and only suppresses transient overvoltage in one direction; the bidirectional model (P6KExxCA) is suitable for AC circuits or signal lines with uncertain polarity, and can achieve bidirectional symmetric protection. You can directly select the model according to your circuit type (DC/AC), or contact our technical team for accurate suggestions.

A: Free sample testing is supported.

A: Bulk purchasing can enjoy exclusive cost-effective discounts and priority supply guarantee; the delivery cycle for bulk conventional models is 15-20 working days. A supply agreement can be signed to ensure delivery stability.

A: All P6KE series products are provided with quality guarantee, with a warranty period of 1 year.

A: The core refers to two key parameters: first, the normal working voltage of the circuit, select the model whose breakdown voltage (VBR) is slightly higher than the working voltage; second, the transient energy, ensure that the peak pulse power (600W) of the product meets the actual absorption demand, with a margin of 1.5-2 times. Our technical team can directly recommend the suitable model according to the circuit parameters you provide.
