What's P6KE series TVS diode?
The P6KE series is a family of axial-leaded TVS diodes commonly used to absorb surges, lightning transients, and electrical noise. Brands such as Littelfuse or Vishay are widely trusted, but their parts can be expensive and not always easy to source quickly. Semiware’s version of the P6KE series doesn’t differ much in terms of performance—what stands out is the balance of cost and availability.
Main features of P6KE200A
Take P6KE200A. Its breakdown window is about 190–210 V with a standoff of 171 V, so it comfortably handles common overvoltage events. The device can take a 600 W surge (10/1000 µs) with roughly 2.2 A peak pulse current. Leakage is very low, around a microamp, which means almost no extra loss in normal operation. It also works over -55 °C to +150 °C, something engineers appreciate in automotive and industrial designs.
Where does it usually show up?
In power modules for PLCs and servo drives, it sits at the AC-DC input to clamp spikes. In cars, it helps protect ECUs or infotainment from load dumps and ignition noise. On RS485 or CAN bus lines, it improves EMC by limiting surge and ESD damage.
Why go for Semiware instead of the big names?
The parts are footprint-compatible (DO-15), so no PCB change is needed. The parameters line up well with the common references from Littelfuse or Vishay. Pricing is often easier on budget, and lead times are more predictable. Reliability has been proven in different customer projects already in the field.
