The Toshiba TLP187 is a DC-input, transistor-output photocoupler that pairs an infrared LED with a high-gain photo-Darlington transistor output stage inside a compact 4-pin SO6 surface-mount package. With a minimum current transfer ratio (CTR) of 1000% and a collector-emitter voltage rating of 300 V, the TLP187 is well suited to driving higher-voltage output stages such as 100 VDC output modules while keeping LED drive current low. A guaranteed 3750 Vrms isolation voltage and recognition under UL 1577, cUL, EN 60747-5-5 (VDE), EN IEC 62368-1 (VDE) and GB 4943.1-2022 (CQC) make it a robust choice for safety-isolated industrial designs.
The TLP187 can be a challenging line item for production buyers when authorized-distributor availability tightens. Pacific Component Xchange is an independent distributor specializing in hard-to-find and allocated power-management ICs and optocouplers. We help engineering and procurement teams secure genuine Toshiba TLP187 photocouplers when standard channels are dry, with authenticity verification, careful handling of moisture-sensitive surface-mount parts, and worldwide shipping. Whether you need a small bridge quantity or full-reel volume, our sourcing specialists can locate stock and lock pricing fast. Request a quote (RFQ) for the TLP187 today and let our team handle obsolete, EOL, and supply-constrained sourcing on your behalf.
The base orderable part number is TLP187. Toshiba's full factory ordering code for the tape-and-reel option is TLP187(TPL,E(T.
It is a single-channel, DC-input transistor-output photocoupler (optocoupler) with a high-gain photo-Darlington transistor output, housed in a 4-pin SO6 surface-mount package.
The TLP187 provides a minimum isolation voltage (BVS) of 3750 Vrms and is recognized under UL 1577, cUL, EN 60747-5-5 (VDE), EN IEC 62368-1 (VDE) and GB 4943.1-2022 (CQC) safety standards.
The TLP187 offers a minimum current transfer ratio (CTR) of 1000% and a collector-emitter voltage VCEO of 300 V, making it suitable for higher-voltage output stages such as 100 VDC modules.
Typical applications include programmable logic controllers (PLCs), I/O interface boards, 100 VDC output modules, and home electric appliances.
