Optocoupler guarantees CTR consistency from 0.2 to 80mA

Toshiba has expanded its optocoupler range with the addition of the TLP383, designed for use in PLCs, AC adapters and I/O interface boards. The photocoupler guarantees the same CTR (Current Transfer Ratio) across an input current range from 0.2 to 8mA [50-600% at IF =0.2/8mA, VCE=5V] and across the temperature range of +25 to 100°C.

The TLP383 features a faster switching speed than standard phototransistor couplers and boasts a turn-off time (tOFF) of just 30μs (at IF=1.6mA, VCC=5V, RL=4.7kΩ).

Housed in a low-height SO6L package the TLP383 has a height of just 2.3mm. Like its smaller family members, the TLP183 and TLP293, the TLP383 incorporates Toshiba's original high output infrared LEDs. It offers a minimum isolation voltage of 5kVrms with minimum creepage and clearance distances of 8mm. It will find application in situations where there are strict height limits and will aid the development of ultra low profile products. Typical applications will include the motherboards of inverter interfaces and general-purpose power supplies.

Operating temperature range is -55 to +125°C, and the photocoupler is approved to UL, cUL, VDE and CQC safety standards.
