MBR120VLSFT1 Surface Mount Schottky Power Rectifier Plastic SOD−123 Package This device uses the Schottky Barrier principle with a large area metal−to−silicon power diode. Ideally suited for low voltage, high frequency rectification or as free wheeling and polarity protection diodes in surface mount applications where compact size and weight are critical to the system. This package also provides an easy to work with alternative to leadless 34 package style. Because of its small size, it is ideal for use in portable and battery powered products such as cellular and cordless phones, chargers, notebook computers, printers, PDAs and PCMCIA cards. Typical applications are AC−DC and DC−DC converters, reverse battery protection, and “Oring” of multiple supply voltages and any other application where performance and size are critical. http://onsemi.com SCHOTTKY BARRIER RECTIFIER 1.0 AMPERES 20 VOLTS Features • • • • • • • Guardring for Stress Protection Optimized for Very Low Forward Voltage 125°C Operating Junction Temperature Epoxy Meets UL 94 V−0 @ 0.125 in Package Designed for Optimal Automated Board Assembly ESD Ratings: Machine Model, C; Human Body Model, 3B Pb−Free Packages are Available SOD−123FL CASE 498 PLASTIC MARKING DIAGRAM Mechanical Characteristics L2VMG G • Reel Options: MBR120VLSFT1 = 3,000 per 7″ reel/8 mm tape • • • • • • • MBR120VLSFT3 = 10,000 per 13″ reel/8 mm tape Device Marking: L2V Polarity Designator: Cathode Band Weight: 11.7 mg (approximately) Case: Epoxy, Molded Finish: All External Surfaces Corrosion Resistant and Terminal Leads are Readily Solderable Lead and Mounting Surface Temperature for Soldering Purposes: 260°C Max. for 10 Seconds Device Meets MSL 1 Requirements L2V = Specific Device Code M = Date Code G = Pb−Free Package (Note: Microdot may be in either location) ORDERING INFORMATION Device Package Shipping † MBR120VLSFT1 SOD−123FL 3000/Tape & Reel MBR120VLSFT1G SOD−123FL (Pb−Free) 3000/Tape & Reel MBR120VLSFT3 SOD−123FL 10000/Tape & Reel MBR120VLSFT3G SOD−123FL 10000/Tape & Reel (Pb−Free) †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. © Semiconductor Components Industries, LLC, 2005 July, 2005 − Rev. 2 1 Publication Order Number: MBR120VLSFT1/D MBR120VLSFT1 MAXIMUM RATINGS Symbol Value Unit Peak Repetitive Reverse Voltage Working Peak Reverse Voltage DC Blocking Voltage Rating VRRM VRWM VR 20 V Average Rectified Forward Current (Rated VR) TL = 119°C IF(AV) 1.0 A Non−Repetitive Peak Surge Current (Surge Applied at Rated Load Conditions, Halfwave, Single Phase, 60 Hz) IFSM 45 A Storage Temperature Range Tstg −65 to +125 °C Operating Junction Temperature TJ −65 to +125 °C dv/dt 1000 V/ms Voltage Rate of Change (Rated VR) Maximum ratings are those values beyond which device damage can occur.

Typical Operating Temperature Derating* 20 r(t), TRANSIENT THERMAL RESISTANCE * Reverse power dissipation and the possibility of thermal runaway must be considered when operating this device under any reverse voltage conditions. Calculations of TJ therefore must include forward and reverse power effects. The allowable operating TJ may be calculated from the equation: TJ = TJmax − r(t)(Pf + Pr) where r(t) = thermal impedance under given conditions, Pf = forward power dissipation, and Pr = reverse power dissipation This graph displays the derated allowable TJ due to reverse bias under DC conditions only and is calculated as TJ = TJmax − r(t)Pr, where r(t) = Rthja. For other power applications further calculations must be performed. 1000 D = 0.5 100 0.2 0.1 0.05 P(pk) 10 0.01 t1 t2 DUTY CYCLE, D = t1/t2 1 SINGLE PULSE qJA = 321.8 °C/W Test Type > Min Pad < Die Size 38x38 @ 75% mils 0.1 0.000001 0.00001 0.0001 0.001 0.01 0.1 t1, TIME (sec) Figure 9.
