TLP383(D4GR-TR,E) – Optocoupler – Toshiba

The Toshiba TLP383 is a high-isolation phototransistor-output photocoupler pairing an InGaAs infrared LED with a photo-transistor in a compact 4-pin SO6L package, rated 5000 Vrms isolation and a -55 to 125 C operating range. The D4GR-TR,E variant adds the VDE (EN60747-5-5) safety option, GR CTR rank, tape-type carrier packaging, and RoHS-compatible construction.

The Toshiba TLP383(D4GR-TR,E) is a low-input-current, high-isolation photocoupler that optically couples an InGaAs infrared emitting diode to a silicon photo-transistor inside a thin, surface-mount 4-pin SO6L package. It is engineered for reliable signal isolation in industrial and power-supply designs, delivering a guaranteed 5000 Vrms isolation voltage and a wide -55 to 125 C operating temperature range while occupying far less board area than a conventional DIP photocoupler.

The ordering suffix decodes as follows: D4 designates the EN60747-5-5 (VDE) safety-approval option, GR specifies the current-transfer-ratio (CTR) rank, TR indicates tape-type carrier packaging, and E denotes RoHS-compatible (lead-free) construction.
