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 IF = 5 mA, VCE = 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.
The TLP185(GB-TPR,SE(T) frequently shows limited authorized-distributor stock, which can stall production schedules. Pacific Component Xchange specializes in sourcing hard-to-find and allocation-constrained power-management ICs and optocouplers. We support customers who need this specific GB-rank, tape-and-reel variant when mainstream channels are dry.
Every order is backed by our commitment to authenticity and quality verification, and we ship globally to keep your line running. Request a quote (RFQ) today for current availability, lead time, and pricing on the Toshiba TLP185(GB-TPR,SE(T), and let our team help you secure this and other hard-to-find components.
The true orderable Toshiba part number is TLP185(GB-TPR,SE(T). The source string had a comma rendered as a period and an unbalanced parenthesis; the clean code is TLP185(GB-TPR,SE(T), also written TLP185-GB-TPR-SE-T.
GB is Toshiba's CTR (current transfer ratio) rank classification. For the TLP185 GB rank, the CTR is specified at 100% to 600% (measured at IF=5mA, VCE=5V), providing strong output drive compared with the standard 50% to 600% blank rank.
The TLP185 provides a minimum isolation voltage of 3750 Vrms (AC, measured for 60 seconds), making it suitable for safety-isolated signal and power applications.
It comes in a low-profile 4-pin SO6 surface-mount package, supplied on tape and reel (the TPR/(T) suffixes denote tape-and-reel packaging).
Yes. The TLP185(SE variant is an active Toshiba product and is widely stocked. Note that the original DIP-substituting base TLP185 is marked Not Recommended for New Design, with the SE surface-mount variant as its successor. Authorized-distributor stock of this specific GB-rank tape-and-reel variant can still be limited, so RFQ pricing is offered.
