TLP185(GB-TPR,SE(T) – Optocoupler – Toshiba

The Toshiba TLP185(GB-TPR,SE(T) is a single-channel phototransistor-output optocoupler in a low-profile 4-pin SO6 surface-mount package, offering 3750 Vrms isolation and a GB-rank current transfer ratio of 100% to 600%.

The Toshiba TLP185(GB-TPR,SE(T) is a single-channel transistor-output photocoupler that pairs a GaAs infrared emitting diode with a silicon phototransistor inside a compact, low-profile 4-pin SO6 surface-mount package. The “GB” rank designates a current transfer ratio (CTR) of 100% to 600% (at I_F = 5 mA, V_CE = 5 V), making this variant well suited to signal-isolation designs that require reliable drive margin. The “TPR” suffix indicates tape-and-reel packaging, and “(T)” denotes the standard reeled shipping format.

With 3750 Vrms isolation (minimum, AC for 60 s), an 80 V collector-emitter voltage rating, and a wide -55°C to +110°C operating temperature range, the TLP185 series is a workhorse isolation device for industrial and consumer power systems. The device carries UL 1577 / cUL recognition and EN 60747-5-5 (VDE) safety approval, and is RoHS compatible.
