Ultra-Miniature SOD-523 High-Speed Switching Diodes | Low Leakage & Fast Recovery
The SOD-523 series features ultra-miniature high-speed switching diodes like 1N4148WT, 1SS400, and BAS521H. These devices offer very low reverse leakage (IRM) and fast reverse recovery time (T<sub>rr</sub>), ideal for space-constrained and high-speed signal switching applications. With forward voltages as low as 0.85V and breakdown voltages up to 300V, they are perfect for portable electronics, telecom systems, and industrial controls.
