The Toshiba TLP184(GB-TPL,SE is an AC-input photocoupler that pairs a phototransistor output stage with two gallium-arsenide (GaAs) infrared LEDs connected in inverse-parallel. Because the input stage responds to current flowing in either direction, the TLP184 can be driven directly from an AC line or bipolar signal source without an external bridge, making it a popular choice for line-voltage status sensing and isolated input boards. The “GB” suffix designates the current-transfer-ratio (CTR) rank, and the “SE” designation indicates the lead-free, RoHS-compliant variant supplied on tape and reel (TPL).
The TLP184(GB-TPL,SE is a specialized AC-input optocoupler that can be subject to allocation and lead-time pressure, which can stall production schedules when stock runs short. Pacific Component Xchange is an independent distributor specializing in hard-to-find and allocated optocouplers and power-management ICs. We help engineers and buyers secure obsolete, end-of-life, and constrained parts through a global sourcing network, with authenticity verification and worldwide shipping. Request a quote (RFQ) for the Toshiba TLP184(GB-TPL,SE today and our team will respond with current pricing, lead time, and available quantities.
The garbled source string resolves to the Toshiba orderable part number TLP184(GB-TPL,SE. 'GB' is the current-transfer-ratio rank, 'TPL' indicates tape-and-reel packaging, and 'SE' is the lead-free, RoHS-compliant variant.
Toshiba classifies photocoupler current transfer ratio (CTR) by rank. The GB rank corresponds to a CTR range of 100% to 600% (measured at IF = 5 mA), giving tighter output predictability than the full unranked device.
Its input stage uses two GaAs infrared LEDs connected in inverse-parallel, so it conducts and emits light on both polarities of current. This lets it be driven directly from an AC source without an external rectifier bridge.
It is supplied in a compact SO6 surface-mount package (4-pin photocoupler footprint) suited to high-density board assembly, on tape and reel.
Major distributors list the SE (lead-free) variant as an active part, though availability can be constrained. Pacific Component Xchange sources it on an RFQ basis.
