HCPL-0201-000E – AVAGO

The HCPL-0201-000E is a high-speed optocoupler in an 8-pin small outline transistor (SOT) package with extended creepage and clearance. Manufactured by Avago Technologies (now Broadcom), it provides 3.75 kVrms of reinforced insulation per UL1577. The device incorporates an AlGaAs LED and an integrated high-gain, high-speed photodiode-transistor detector. The output stage features a push-pull output configuration, enabling high common-mode transient immunity (typically >10 kV/µs) and eliminating the need for a pull-up resistor in many applications. The HCPL-0201-000E is designed for digital logic interfacing, providing TTL/CMOS compatibility. Propagation delay times are typically in the nanosecond range, making it suitable for high-speed data transmission and isolation in industrial and instrumentation applications where safety isolation and noise immunity are critical.
