Vishay Semiconductor Opto Division SFH6319T

1Транзистор с базой-55°C ~ 100°C

Overview

Very high current ratio together with 4000 VRMS isolation are achieved by coupling an LED with an integrated high gain photo detector in a SOIC-8 package. Separate pins for the photo diode and output stage enable TTL compatible saturation voltages with high speed operation. Photodarlington operation is achieved by tying the VCC and VO terminals together. Access to the base terminal allows adjustment to the gain bandwidth. The SFH6318T is ideal for TTL applications since the 300 % minimum current transfer ratio with an LED current of 1.6 mA enables operation with one unit load-in and one unit load-out with a 2.2 kΩ pull-up resistor. 

The SFH6319T is best suited for low power logic applications involving CMOS and low power TTL. A 400 % current transfer ratio with only 0.5 mA of LED current is guaranteed from 0 °C to 70 °C. Caution: Due to the small geometries of this device, it should be handled with electrostatic discharge (ESD) precautions. Proper grounding would prevent damage further and/or degradation which may be induced by ESD.
