Optocoupler Provides High Breakdown Voltage and Current Amplification up to 110 C

Toshiba Electronics Europe (TEE) has announced a new optocoupler for use with programmable logic controllers (PLCs), I/O interface boards and home appliances. With a current transfer ratio of 1000% (min) and a minimum rated isolation voltage of 3750Vrms the TLP187 is designed for use in programmable controllers, white goods, and other applications that utilize 100Vdc output modules.

The TLP187 combines a long-life gallium aluminum arsenide (GaAlAs) infrared light-emitting diode (LED) optically coupled to a Darlington transistor to provide high noise immunity and high insulation. The device can be operated over a wide temperature range of -55°C to 110°C.

Housed in an ultra-miniature S06 package, TLP187 has minimum creepage distance and clearance distance of min. 5mm, the internal isolation thickness is > 0.4mm and the maximum package height is just 2.3mm. The TLP187 has a collector current (dc)IC of 150 mA and high collector-emitter breakdown voltage of 300V(BR)CEO. The TLP187 supports reflow mounting in accordance with JEDEC standards and meets the requirements of the international safety standards like UL, cUL, and VDE.
