MBRM120L Surface Mount Schottky Power Rectifier POWERMITE® Power Surface Mount Package The Schottky Powermite® employs the Schottky Barrier principle with a barrier metal and epitaxial construction that produces optimal forward voltage drop−reverse current tradeoff. The advanced packaging techniques provide for a highly efficient micro miniature, space saving surface mount Rectifier. With its unique heatsink design, the Powermite® has the same thermal performance as the SMA while being 50% smaller in footprint area, and delivering one of the lowest height profiles, < 1.1 mm in the industry. 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 POWERMITE CASE 457 PLASTIC Features • • • • • • • ANODE CATHODE Low Profile − Maximum Height of 1.1 mm Small Footprint − Footprint Area of 8.45 mm2 Low VF Provides Higher Efficiency and Extends Battery Life Supplied in 12 mm Tape and Reel Low Thermal Resistance with Direct Thermal Path of Die on Exposed Cathode Heat Sink ESD Ratings: Human Body Model, 3B u 16000 V Machine Model, C u 400 V Pb−Free Packages are Available MARKING DIAGRAM M BCF G Mechanical Characteristics: • • • • • Powermite® is JEDEC Registered as D0−216AA Case: Molded Epoxy Epoxy Meets UL 94 V−0 @ 0.125 in Weight: 16.3 mg (Approximately) Lead and Mounting Surface Temperature for Soldering Purposes: 260°C Maximum for 10 Seconds M = Date Code BCF = Device Code G = Pb−Free Package ORDERING INFORMATION Device MBRM120LT1 Package Shipping† POWERMITE 3000/Tape & Reel MBRM120LT1G POWERMITE 3000/Tape & Reel (Pb−Free) MBRM120LT3 POWERMITE 12000/Tape & Reel MBRM120LT3G POWERMITE 12000/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, 2007 February, 2007 − Rev. 6 1 Publication Order Number: MBRM120L/D MBRM120L MAXIMUM RATINGS Rating Symbol Value Unit VRRM VRWM VR 20 V IO 1.0 A Peak Repetitive Forward Current (At Rated VR, Square Wave, 100 kHz, TC = 135°C) IFRM 2.0 A Non−Repetitive Peak Surge Current (Non−Repetitive peak surge current, halfwave, single phase, 60 Hz) IFSM 50 A Storage Temperature Tstg −55 to 150 °C Operating Junction Temperature TJ −55 to 125 °C dv/dt 10,000 V/ms Rtjl Rtjtab Rtja 35 23 277 °C/W Peak Repetitive Reverse Voltage Working Peak Reverse Voltage DC Blocking Voltage Average Rectified Forward Current (At Rated VR, TC = 135°C) Voltage Rate of Change (Rated VR, TJ = 25°C) THERMAL CHARACTERISTICS Thermal Resistance, Junction−to−Lead (Anode) (Note 1) Thermal Resistance, Junction−to−Tab (Cathode) (Note 1) Thermal Resistance, Junction−to−Ambient (Note 1) Stresses exceeding Maximum Ratings may damage the device.

Typical Operating Temperature Derating* * 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 = TJmax − r(t)(Pf + Pr) where TJ may be calculated from the equation: 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. http://onsemi.com 3 R(T), TRANSIENT THERMAL RESISTANCE (NORMALIZED) R(T), TRANSIENT THERMAL RESISTANCE (NORMALIZED) MBRM120L 1.0 50% 20% 0.1 10% 5.0% 0.01 2.0% 1.0% Rtjl(t) = Rtjl*r(t) 0.001 0.00001 0.0001 0.001 0.01 1.0 0.1 10 100 T, TIME (s) Figure 9.
