LESHAN RADIO COMPANY, LTD. SCHOTTKY Barrier Diode BAS70LT1 These Schottky barrier diodes are designed for high speed switching applications, circuit protection, and voltage clamping. 3 Extremely low forward voltage reduces conduction loss. Miniature surface mount package is excellent for hand held and 1 2 CASE 318-08, STYLE 11 portable applications where space is limited.
