| LESHAN RADIO COMPANY, LTD. Schottky Barrier Diodes Schottky barrier diodes are designed primarily for high-efficiency UHF and VHF detector applications. Readily available to many other fast switching RF and digital applications. They are housed in the SOT-323/SC-70 package which is designed for low-power surface mount applications. * Extremely Low Minority Carrier Lifetime * Very Low Capacitance * Low Reverse Leakage * Available in 8 mm Tape and Reel MMBD110T1 MMBD330T1 MMBD770T1 3 1 2 CASE 419-02, STYLE 2 DEVICE MARKING MMBD110T1 = 4M MAXIMUM RATINGS Rating Reverse Voltage SOT-323 /SC - 70 MMBD330T1 = 4T MMBD770T1 = 5H Symbol VR Value 7.0 30 70 120 -55 to +125 -55 to +150 C Typ 10 -- -- 0.88 0.9 0.5 20 13 9.0 6.0 0.5 0.38 0.52 0.42 0.7 Unit Vdc MMBD110T1 MMBD330T1 MMBD770T1 Forward Power Dissipation TA = 25C Junction Temperature Storage Temperature Range PF TJ Tstg mW C ELECTRICAL CHARACTERISTICS (TA = 25C unless otherwise noted) Characteristic Symbol Min Reverse Breakdown Voltage V(BR)R (IR = 10 A) MMBD110T1 7.0 MMBD330T1 MMBD770T1 Diode Capacitance (VR = 0, f = 1.0 MHZ, Note 1) (VR = 15 Volts, f = 1.0 MHZ) (VR = 20 Volts, f = 1.0 MHZ) Reverse Leakage (VR = 3.0 V) (VR = 25 V) (VR = 35 V) Noise Figure (f = 1.0 GHz, Note 2) Forward Voltage (IF = 10 mA) (IF= 1.0 mAdc) (IF = 10 mA) (IF = 1.0 mAdc) (IF = 10 mA) CT MMBD110T1 MMBD330T1 MMBD770T1 IR MMBD110T1 MMBD330T1 MMBD770T1 NF MMBD110T1 VF MMBD110T1 MMBD330T1 MMBD770T1 -- -- -- -- -- -- -- -- -- -- -- -- 30 70 Max -- -- -- Unit Volts pF 1.0 1.5 1.0 nAdc 250 200 200 dB -- Vdc 0.6 0.45 0.6 0.5 1.0 MMBD110. 330. 770T1-1/4 LESHAN RADIO COMPANY, LTD.
