Datasheet Summary with AI

## Characteristics

· Forward voltage (Vf): 0.54 - 1.00 V (depending on type).
· Leakage current (IR): < 50 nA at VR = 100V (depending on type).
· Reverse recovery time (trr): < 4-50 ns (depending on type and temperature).

Type Specific Details
· LL4148: VRRM = 75V, I_FAV = 150mA, I_FSM = 2000mA
· LL4150: VRRM = 50V, I_FAV = 200mA, I_FSM = 4000mA
· LL4151: VRRM = 50V, I_FAV = 200mA, I_FSM = 2000mA
· LL4448: VRRM = 75V, I_FAV = 300mA, I_FSM = 2000mA

## Notes
· Performance is dependent on mounting to a P.C. board with 25 mm² copper pads.
