Schottky diodes offer low forward voltage and fast switching but suffer from higher leakage at high temperatures. SBRs (Super Barrier Rectifiers) provide a similar low forward voltage but with better thermal stability and lower leakage.
Diodes, Rectifiers & Arrays Component Intelligence
Select the right rectification topology for efficiency and thermal management.
What are Diodes, Rectifiers & Arrays components?
Diodes and rectifiers are fundamental for power conversion and signal steering. Selection hinges on balancing forward voltage drop (efficiency) against reverse leakage and recovery speed. For high-frequency switching, prioritize ultra-fast or Schottky types to minimize losses.
How to Choose Diodes, Rectifiers & Arrays Components
Focus on the application's switching frequency and thermal constraints to narrow your search.
Forward Voltage (Vf)
Lower Vf reduces conduction losses, critical for high-current power supplies and battery-operated devices.
Reverse Recovery Time (trr)
Essential for high-frequency switching; choose ultra-fast or Schottky diodes to minimize switching losses.
Thermal Management
Evaluate package thermal resistance (Rth) and junction temperature ratings to ensure reliability under peak load.
Reverse Leakage Current
Crucial in high-temperature environments where leakage can lead to thermal runaway.
Package & Mounting
Match the footprint to your PCB thermal dissipation capabilities, such as TO-220 for heatsinking or SMD for compact designs.
