What does the GR suffix mean on the TLP385?

GR designates the current transfer ratio (CTR) rank. Per Toshiba's Table 8.1, the GR rank covers a CTR of 100% to 300% measured at IF = 5 mA, VCE = 5 V. Other ranks for the TLP385 include GB (100% to 600%) and BL (200% to 600%).

What package does the TLP385(GR-TPL,E) use?

It is supplied in a 4-pin SO6L surface-mount package, with the TPL,E suffix indicating the tape-and-reel surface-mount variant.

What is the isolation voltage of the TLP385?

The TLP385 is a high-isolation photocoupler guaranteeing a minimum isolation voltage of 5000 Vrms (AC, 60 s).

What are the collector-emitter and current ratings?

The phototransistor output has a collector-emitter voltage (VCEO) rating of 80 V and an emitter-collector voltage (VECO) of 7 V, with maximum forward current and collector current of 50 mA each.

What is the operating temperature range of the TLP385?

The TLP385 operates over -55 C to 110 C and is storage-rated from -55 C to 125 C.

Is the TLP385(GR-TPL,E) available to purchase?

Yes. Although this specific GR-rank variant can be constrained at authorized distributors, Pacific Component Xchange can source it. Submit an RFQ for current availability and pricing.

The Toshiba TLP385(GR-TPL,E) is a high-isolation, single-channel transistor-output photocoupler (optocoupler) built from a GaAs infrared emitting diode optically coupled to a silicon phototransistor. The “GR” suffix designates the current-transfer-ratio (CTR) rank, while “TPL,E” indicates the surface-mount tape-and-reel packaging variant. Housed in a compact 4-pin SO6L surface-mount package, it is designed for high galvanic isolation between low-voltage logic and higher-voltage circuitry.
