TLP291-4(GB-TP,E) – Optocoupler – Toshiba

The Toshiba TLP291-4(GB-TP,E) is a quad-channel (4-channel) DC-input, phototransistor-output optocoupler rated for 2500 Vrms isolation in a surface-mount 16-pin SOIC package.

The Toshiba TLP291-4(GB-TP,E) is a four-channel transistor-output photocoupler that integrates four infrared LEDs optically coupled to four NPN phototransistors within a single surface-mount 16-pin SOIC (SO16) package. Each channel provides galvanic isolation rated at 2500 Vrms, making the device well suited for high-density signal isolation in industrial and power-conversion equipment. The “(GB-TP,E)” suffix denotes the GB current-transfer-ratio rank, tape-and-reel packing, and RoHS-compatible (lead-free) finish.

Key Features

• 4 isolated channels in a single SO16 surface-mount package
• DC input, NPN phototransistor output
• Isolation voltage: 2500 Vrms (BV)
• Current transfer ratio (CTR): 100% to 400% at I_F = 5 mA (GB rank)
• Collector-emitter voltage (V_CEO): 80 V
• Forward current (I_F): 50 mA maximum
• RoHS-compatible, lead-free, surface-mount construction

Applications

• Programmable logic controllers (PLCs)
• Switching power supplies and AC/DC converters
• Industrial automation and I/O isolation
• Data transmission (simplex/multiplex) interfaces
• Home appliances and instrumentation

Why Source TLP291-4(GB-TP,E) from Pacific Component Xchange

Pacific Component Xchange is an independent distributor specializing in hard-to-find and allocation-constrained power-management ICs and optocouplers. The TLP291-4(GB-TP,E) frequently sees limited authorized-distributor availability, and our global sourcing network helps engineers and buyers secure this quad-channel optocoupler when standard channels are out of stock. Every unit is inspected for authenticity and traceability, and we ship worldwide. Submit a Request for Quote (RFQ) today and our team will provide current pricing, lead time, and stock for your required quantity, including obsolete and end-of-life sourcing support.
