MBR0540T1, MBR0540T3 Surface Mount Schottky Power Rectifier SOD-123 Power Surface Mount Package The Schottky Power Rectifier employs the Schottky Barrier principle with a barrier metal that produces optimal forward voltage drop-reverse current tradeoff. Ideally suited for low voltage, high frequency rectification, or as a free wheeling and polarity protection diodes in surface mount applications where compact size and weight are critical to the system. This package provides an alternative to the leadless 34 MELF style package. These state-of-the-art devices have the following features: * * * * Guardring for Stress Protection Very Low Forward Voltage Epoxy Meets UL94, VO at 1/8 Package Designed for Optimal Automated Board Assembly http://onsemi.com SCHOTTKY BARRIER RECTIFIER 0.5 AMPERES 40 VOLTS Mechanical Characteristics: * * * * * * * * Reel Options: 3,000 per 7 inch reel/8 mm tape Reel Options: 10,000 per 13 inch reel/8 mm tape Device Marking: B4 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: 260C max. for 10 Seconds SOD-123 CASE 425 STYLE 1 MARKING DIAGRAM B4 B4 = Device Code MAXIMUM RATINGS Rating Symbol Value Unit Peak Repetitive Reverse Voltage Working Peak Reverse Voltage DC Blocking Voltage VRRM VRWM VR 40 V Average Rectified Forward Current (At Rated VR, TC = 115C) IO 0.5 ORDERING INFORMATION Device Peak Repetitive Forward Current (At Rated VR, Square Wave, 20 kHz, TC = 115C) IFRM 1.0 A Non-Repetitive Peak Surge Current (Surge Applied at Rated Load Conditions Halfwave, Single Phase, 60 Hz) IFSM 5.5 A Tstg, TC -55 to +150 C TJ -55 to +150 C dv/dt 1000 V/s Storage/Operating Case Temperature Range Operating Junction Temperature Voltage Rate of Change (Rated VR, TJ = 25C) Semiconductor Components Industries, LLC, 2000 October, 2000 - Rev. 4 Package Shipping MBR0540T1 SOD-123 3000/Tape & Reel MBR0540T3 SOD-123 10,000/Tape & Reel A 1 Publication Order Number: MBR0540T1/D MBR0540T1, MBR0540T3 THERMAL CHARACTERISTICS Rating Thermal Resistance - Junction-to-Lead (Note 1.)

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) MBR0540T1, MBR0540T3 1E+00 50% 20% 1E-01 10% 5.0% 2.0% 1.0% 1E-02 Rtjl(t) = Rtjl*r(t) 1E-03 0.00001 0.0001 0.001 0.01 0.1 1.0 10 100 1,000 10 100 1,000 T, TIME (s) Figure 9.
