The TLP291GR(GR-TP.SE) is a four-pin photocoupler from Toshiba Semiconductor and Storage, consisting of an infrared emitting diode (IRED) optically coupled to a phototransistor. It provides electrical isolation between input and output circuits. The GR likely refers to a higher gain or a specific CTR range. The (GR-TP.SE) likely denotes specific tape and reel packaging and sorting options.

Applications

• Programmable Logic Controllers (PLCs)
• Factory automation equipment
• Measuring instruments
• Telecommunication equipment
• Office automation equipment

Features

• High Isolation Voltage: Typically 3750 Vrms
• Compact Package: 4-pin SO6
• Operating Temperature: -30°C to 100°C
• Higher CTR (Current Transfer Ratio) than standard TLP291
• Lead-Free Construction

Benefits

• Offers electrical isolation, protecting sensitive circuits from voltage surges and noise.
• Saves board space due to its compact size.
• Ensures reliable operation in a wide temperature range.
• Provides enhanced signal transfer efficiency due to the higher CTR.
• Complies with environmental regulations.

Additional Details

The TLP291GR(GR-TP.SE) features a high isolation voltage, typically around 3750 Vrms, ensuring robust electrical isolation. Its compact 4-pin SO6 package makes it suitable for space-constrained designs. The device operates reliably from -30°C to 100°C. The 'GR' designation suggests a higher Current Transfer Ratio (CTR) compared to the standard TLP291, enhancing signal transfer. It is lead-free and adheres to environmental regulations. The (GR-TP.SE) probably specifies particular tape and reel packaging for automated assembly and possibly sorting criteria for specific electrical characteristics.
