Its 5000Vrms isolation rating covers reinforced insulation requirements for motor drives, PLC I/O modules, and SMPS feedback loops. The current transfer ratio (CTR) is specified at 100% to 200% at a forward current of 5mA — a tight bin that gives the designer predictable gain margin without overdriving the LED. The 80V output rating handles 48V bus monitoring and high-side switching without a secondary clamp. ## Temperature range and switching speed The typical rise and fall times are 2µs and 3µs, with turn-on/turn-off times of 3µs each — fast enough for 100 kHz switching regulators and serial data isolation at 115.2 kbps. The 300mV Vce saturation max keeps the output drop low when driving logic inputs or a downstream transistor base. ## Package and mounting Housed in a 6-SOIC package with 4 leads (the two center pins are omitted for creepage distance), it occupies the same footprint as a standard SOIC-8 but with wider pin spacing for high-voltage clearance. Surface-mount assembly with standard reflow profiles works; the part is RoHS compliant per the listing. The 50mA continuous output current per channel is adequate for driving a gate driver or a low-power relay coil directly.","metaTitle":"TLP385(GRL-TPL,E Optocoupler, 5000Vrms Isolation","metaDescription":"Toshiba TLP385(GRL-TPL,E transistor output optocoupler, 5000Vrms isolation, 100-200% CTR at 5mA, -55°C to 110°C, 6-SOIC.
