TLP2355 – Optocoupler – Toshiba

The Toshiba TLP2355 is a single-channel high-speed logic-output optocoupler in an SO6 package, pairing a GaAlAs infrared LED with a high-gain photo-IC totem-pole output and 3.75 kVrms isolation.

The Toshiba TLP2355 is a single-channel, high-speed logic-output optocoupler that couples a GaAlAs infrared LED with a high-gain, high-speed photo detector IC. The detector features a totem-pole output stage capable of both current sourcing and current sinking, making it well suited to driving logic-level loads across an isolation barrier. High common-mode transient immunity supports reliable operation in electrically noisy power-electronics environments.

Key Features

• Single-channel (1-channel) digital / logic output optocoupler
• Totem-pole output stage with current sourcing and sinking capability
• Supply voltage range: 3 V to 20 V
• Threshold input current: 1.6 mA (max)
• Propagation delay time: 250 ns (max)
• Data rate: 5 Mbps
• Common-mode transient immunity: +/-20 kV/us (min)
• Isolation voltage: 3.75 kVrms (BVS)
• Operating temperature range: -40 C to +125 C
• SO6 surface-mount package (5-pin SOIC outline)

Applications

• Intelligent Power Module (IPM) gate-signal isolation
• Programmable Logic Controllers (PLCs)
• Isolated digital logic interfaces
• Industrial inverters and motor control
• Switching power supplies
