SK510SMA-AQ - Safety on the Road: How a Small Schottky Can Make a Big Difference

Every day, countless trucks travel on our highways, delivering essential goods: food, medicine, clothing, and raw materials for industry. Without them, daily life—and the economy—would grind to a halt. However, the presence of these heavy-duty vehicles also increases the risk of accidents. That’s why visibility is critical. Modern LED lighting has revolutionized truck safety by providing brighter output, a longer lifespan, and lower power consumption compared to old incandescent lamps, which is especially important when trucks are parked overnight.

However, these LED systems require robust protection from harsh electrical environments, including voltage spikes and incorrect battery polarity.

This is where the SK510SMA-AQ by Diotec Semiconductor comes in. It's a compact, powerful 5 A/100 V Schottky diode in a DO-214AC/SMA package. Designed specifically for heavy-duty applications, it's ideal for protecting rear, brake, and parking LED lights in commercial vehicles.

Key specs:

  • 5 A forward current
  • 100 V reverse voltage
  • <850 mV forward voltage drop @ 5 A
  • <100 µA reverse leakage @ 100 V
  • Compact 5 x 2.7 mm footprint

 This small component plays a big role in ensuring the safety and reliability of the transportation systems we depend on. Get the data sheet here.
