| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MBRM120ET3/D Designer'sTM Data Sheet Surface Mount Schottky Power Rectifier MBRM120ET3 SCHOTTKY BARRIER RECTIFIER 1.0 AMPERES 20 VOLTS POWERMITE(R) 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. Features: * 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 -- 12,000 Units per Reel * Low Thermal Resistance with Direct Thermal Path of Die on Exposed Cathode Heat Sink Mechanical Characteristics: * Powermite is JEDEC Registered as D0-216AA * Case: Molded Epoxy * Epoxy Meets UL94, VO at 1/8 * Weight: 62 mg (approximately) * Device Marking: BCV * Lead and Mounting Surface Temperature for Soldering Purposes. 260C Maximum for 10 Seconds MAXIMUM RATINGS Rating Peak Repetitive Reverse Voltage Working Peak Reverse Voltage DC Blocking Voltage Average Rectified Forward Current (At Rated VR, TC = 130C) Peak Repetitive Forward Current (At Rated VR, Square Wave, 20 kHz, TC = 135C) Non-Repetitive Peak Surge Current (Non-Repetitive peak surge current, halfwave, single phase, 60 Hz) Storage Temperature Operating Junction Temperature Voltage Rate of Change (Rated VR, TJ = 25C) Symbol VRRM VRWM VR IO IFRM IFSM Tstg TJ dv/dt Value 20 Unit V ANODE CATHODE CASE 457-04 ISSUE C 1.0 2.0 50 -65 to 150 -65 to 150 10,000 A A A C C V/ms THERMAL CHARACTERISTICS Thermal Resistance - Junction-to-Lead (Anode) (1) Thermal Resistance - Junction-to-Tab (Cathode) (1) Thermal Resistance - Junction-to-Ambient (1) Rtjl Rtjtab Rtja 35 23 277 C/W (1) Mounted with minimum recommended pad size, PC Board FR4, See Figures 9 and 10.

Typical Operating Temperature Derating* R (T) , TRANSIENT THERMAL RESISTANCE (NORMALIZED) * 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. 1.0 50% 20% 0.1 10% 5.0% 2.0% 1.0% Rtjl(t) = Rtjl*r(t) 0.001 0.00001 0.01 0.0001 0.001 0.01 T, TIME (s) 0.1 1.0 10 100 Figure 9.
