TLP185(GB-TPL,E) – Optocoupler – Toshiba
The Toshiba TLP185(GB-TPL,E) is a single-channel phototransistor-output optocoupler (GB current transfer ratio rank) in a compact SO6 surface-mount package, rated for 3750 Vrms isolation.
The Toshiba TLP185(GB-TPL,E) is a single-channel photocoupler that pairs a GaAs infrared emitting diode with a silicon phototransistor in a small-outline SO6 surface-mount package. Designed as a space-saving alternative to traditional DIP optocouplers, it is well suited to high-density boards in industrial control, power supply, and signal-isolation designs. The GB suffix denotes the device’s binned current transfer ratio (CTR) rank, while the -TPL,E code identifies tape-and-reel packaging.
Key Features
- Single-channel (1-channel) phototransistor-output optocoupler
- CTR rank GB: 100% minimum to 600% maximum (IF = 5 mA, VCE = 5 V)
- Isolation voltage: 3750 Vrms (minimum)
- Collector-emitter voltage (VCEO): 80 V (minimum)
- Absolute maximum input forward current (IF): 50 mA
- Collector-emitter saturation voltage: 300 mV (maximum, Rank GB at IC = 0.2 mA, IF = 1 mA)
- Operating temperature range: -55 °C to +110 °C
- Compact SO6 surface-mount package (6-pin outline, 4 active leads)
- Safety standards: UL1577 (UL-approved), cUL/CSA, VDE EN60747-5-5 (with option V4), and CQC
Applications
- Programmable logic controllers (PLCs) and I/O interface boards
- AC adapters and switch-mode power supplies
- Office and industrial equipment
- Signal isolation across high-voltage barriers
- Instrumentation and home appliances
