The TLP124BV from Toshiba is a 1-channel photocoupler with 50-300% CTR, 5000Vrms isolation, and 10Mbps data rate in MFSOP-4 for signal isolation.
The TLP124BV is a 1-channel phototransistor photocoupler from Toshiba in MFSOP-4 (half-size DIP) with 50-300% CTR and 5000Vrms isolation. When forward current flows through the input LED (pins 1-2), it emits infrared light (typically 940nm wavelength) that is detected by the phototransistor on the output side (pins 4-5). The photons generate electron-hole pairs in the phototransistor base region, creating a base current that is amplified by the transistor hFE. The CTR (Current Transfer Ratio) of 50-300% means the output collector current can be 0.5x to 3x the input LED current. The base pin (pin 6) is accessible for speed enhancement: connecting a resistor from base to emitter reduces storage time from approximately 18us to 3us at the cost of reduced CTR. The 5000Vrms isolation voltage provides reinforced insulation between input and output circuits.
