SMA package surface mount Schottky diode, ideal for low voltage, high frequency rectification, or as free wheeling and polarity diodes in surface mount applications where compact size and weight are critical to the system.
The MBRA140T3 Schottky barrier rectifier is designed for low‑voltage, high‑frequency rectification, free‑wheeling, and polarity‑diode applications where compact size and weight are critical. It features an epoxy‑molded case, oxide‑passivated junction, and a guard‑ring for stress protection.
Key specifications include a 40 V peak repetitive reverse voltage, 1 A average forward current, 2 A peak forward current, and a 30 A non‑repetitive surge rating. Thermal resistance is 35 °C/W (junction‑to‑lead) and the device can be soldered up to 260 °C for 10 seconds. The part is supplied in a 12 mm tape, 5000 units per 13‑inch reel.
