TLP385(GR-TPL,E) – Optocoupler – Toshiba

About this part

The Toshiba TLP385(GR-TPL,E) is a high-isolation, transistor-output photocoupler that pairs a gallium-arsenide (GaAs) infrared LED with a silicon phototransistor inside a small, thin 4-pin SO6L surface-mount package. The “GR” suffix designates the current-transfer-ratio (CTR) rank, with a guaranteed CTR range of 100-300%, making it well suited to designs that demand reliable signal transfer with predictable gain. With a guaranteed isolation voltage of 5000 Vrms, this device provides robust galvanic separation between primary and secondary circuits for industrial and power applications.

Key Features

• Transistor-output photocoupler (GaAs IR LED + phototransistor), 1 channel
• GR rank: current transfer ratio (CTR) 100-300%
• Isolation voltage: 5000 Vrms (min)
• Collector-emitter voltage (V_CEO): 80 V (min)
• Forward current (I_F): 50 mA max
• Compact, thin 4-pin SO6L surface-mount package for high-density mounting
• UL1577 recognized (File No. E67349); suitable for safety-critical isolation

Applications

• Programmable logic controllers (PLCs)
• AC adapters and switching power supplies
• I/O interface boards
• Communication and digital signal isolation
• Industrial automation equipment
