LMBR0520T1G

LESHAN RADIO COMPANY, LTD. Surface Mount Schottky Power Rectifier Pb-Free package is available LMBR0520T1G 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 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 (0.38 V Max @ 0.5 A, 25°C) • 125°C Operating Junction Temperature • Epoxy Meets UL94, VO at 1/8″ • Package Designed for Optimal Automated Board Assembly SOD–123 Mechanical Characteristics • Reel Options: LMBR0520T1G = 3,000 per ″7 reel / 8 mm tape. Reel Options: LMBR0520T3G = 10,000 per ″ 13 reel / 8 mm tape. • Device Marking: B2 • 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 MAXIMUM RATINGS Rating Symbol Value Unit Peak Repetitive Reverse Voltage Working Peak Reverse Voltage DC Blocking Voltage VRRM VRWM VR 20 Volts Average Rectified Forward Current (Rated VR) TL = 90°C IF(AV) 0.5 Amps Non–repetitive Peak Surge Current (Surge applied at rated load conditions halfwave, single phase, 60 Hz) IFSM 5.5 Amps Storage Temperature Tstg – 65 to +125 °C TJ – 65 to +125 °C dv/dt 1000 V/µs Thermal Resistance — Junction to Ambient (1) RθJA 340 °C/W Thermal Resistance — Junction to Lead RθJL 150 °C/W Operating Junction Temperature Voltage Rate of Change (Rated VR) THERMAL CHARACTERISTICS ELECTRICAL CHARACTERISTICS Maximum Instantaneous Forward Voltage (2) (iF = 0.1 Amps) (iF = 0.5 Amps) Maximum Instantaneous Reverse Current (2) (VR = 10 V) (Rated dc Voltage = 20 V) VF IR TJ = 25°C TJ = 100°C 0.300 0.385 0.220 0.330 TJ = 25°C TJ = 100°C 75 µA 250 µA 5 mA 8 mA Volts mA (1) FR–4 or FR–5 = 3.5 x 1.5 inches using the Motorola minimum recommended footprint.
