| Schottky Barrier Diodes (SBD) MA3J745D Silicon epitaxial planar type Unit : mm For switching circuits I Features * Optimum for low-voltage rectification because of its low forward rise voltage (VF) * Optimum for high-frequency rectification because of its short reverse recovery time (trr) 2.1 0.1 0.425 1.25 0.1 0.425 + 0.1 2.0 0.2 1.3 0.1 0.65 0.65 1 3 2 I Absolute Maximum Ratings Ta = 25C Parameter Reverse voltage (DC) Peak reverse voltage Forward current (DC) Peak forward current Single Double* Single Double* Tj Tstg IFM Symbol VR VRM IF Rating 30 30 30 20 150 110 125 -55 to +125 C C mA Unit V V mA 0.9 0.1 1 : Cathode 1 2 : Cathode 2 3 : Anode 1, 2 EIAJ : SC-70 Flat S-Mini Type Package (3-pin) Marking Symbol: M3E Internal Connection 1 3 2 Junction temperature Storage temperature Note) * : Value per chip I Electrical Characteristics Ta = 25C Parameter Reverse current (DC) Forward voltage (DC) Symbol IR VF1 VF2 Terminal capacitance Reverse recovery time* Ct trr VR = 30 V IF = 1 mA IF = 30 mA VR = 1 V, f = 1 MHz IF = IR = 10 mA Irr = 1 mA, RL = 100 Vin = 3 V(peak), f = 30 MHz RL = 3.9 k, CL = 10 pF 1.5 1.0 Conditions Min Typ Max 30 0.3 1.0 Unit A V V pF ns Detection efficiency 65 0.15 - 0.05 + 0.1 0.3 - 0 % Note) 1. Schottky barrier diode is sensitive to electric shock (static electricity, etc.). Due attention must be paid on the charge of a human body and the leakage of current from the operating equipment. 2.
