SB140 / SB160 1A Schottky Barrier Rectifiers are 1 ampere operation schottky barrier rectifiers suitable for low voltage, high frequency inverters, free wheeling, and polarity protection applications. The product features no thermal runaway and exceeds the environmental standards of MIL-S-19500/228.
The SB140 and SB160 are 1 A Schottky barrier rectifiers designed for low‑voltage, high‑frequency inverter free‑wheeling and polarity protection applications. They are supplied in a DO‑41 plastic package with moulded plastic case and colour‑band cathode identification.
Key specifications include maximum reverse voltages of 40 V (SB140) and 60 V (SB160), forward voltage drops of 0.5 V/0.7 V at 1 A, typical junction capacitance of 110 pF, and an operating temperature range of –50 °C to +125 °C. Mechanical data such as axial leads and solderable terminals comply with MIL‑STD‑202.
