Toshiba Introduces New Transistor-Output Photocoupler

Ultra-Thin, Low Input Current Type Provides Faster Switching Speed, Delivers 45 Percent Height Reduction

IRVINE, Calif., July 14, 2015 — (PRNewswire) —   Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced the launch of a new low-input current drive transistor output photocoupler.  Housed in a thin SO6L package, the TLP383 is suited to programmable logic controllers, A/C adaptors and I/O interface boards, and can be used to replace conventional DIP4 pin package products.

Toshiba's new low-input current drive transistor output photocoupler is suited to programmable logic controllers, A/C adaptors and I/O interface boards. It can be used to replace conventional DIP4pin package products.

The TLP383 features a faster switching speed than standard phototransistor couplers, as well as a turn-off time (tOFF) of just 30μs (at IF=1.6mA, VCC=5V, RL=4.7kΩ). It incorporates Toshiba's original high output infrared LEDs, and provides the same CTR (Current Transfer Ratio) across an input current range from 0.2mA to 8mA [50-600 percent at IF =0.2mA/8mA, VCE=5V] and across the temperature range of 25°C to 100°C.

With a height of just 2.3mm (max) - an approximately 45 percent reduction from Toshiba's conventional DIP4 package products - the TLP383 is well-suited to applications with strict height limitations and aids in the development of ultra-low profile products. At the same time, the TLP383 has an isolation specification equivalent to DIP4 wide lead type package products, and provides a creepage and clearance distance of 8mm (min), and isolation voltage of 5000Vrms (min).
