The TLP185(GR-TPLSE(T is a small outline photorelay manufactured by Toshiba Semiconductor and Storage. It consists of a gallium arsenide infrared emitting diode optically coupled to a silicon phototransistor. It is designed for use in a wide range of applications requiring electrical isolation between control circuits and load circuits.

Applications:

• Programmable Logic Controllers (PLCs)
• I/O interfaces
• Solid-state relays (SSRs)
• Measuring instruments
• Office automation equipment

Features:

• Small outline package
• High isolation voltage
• Low input current
• High switching speed
• Lead-free construction
• Guaranteed performance from -55 to 110°C

Benefits:

• Provides electrical isolation between control and load circuits, protecting sensitive control circuitry from high voltages and transients.
• Reduces power consumption due to low input current requirement.
• Enables fast switching speeds for high-frequency applications.
• Small size allows for use in compact electronic devices.

Additional Details:

The TLP185(GR-TPLSE(T features a high isolation voltage, typically around 3750Vrms, which provides excellent protection against voltage surges and electrical noise. The typical turn-on and turn-off times are in the microseconds range, making it suitable for relatively fast switching applications. The device is RoHS compliant and lead-free. The 'GR' in the part number likely refers to a specific ranking or testing grade within Toshiba's manufacturing process. The package is a SO4 type. The forward current is typically 10mA. It can be used for signal isolation or as a solid-state relay driver.
