Broadcom DC Input 2-Channel Surface Mount Optocoupler SOIC, 1.7V Max Forward Voltage, 50mA, 3.75kVrms HCPL-053L-000E

Broadcom HCPL-053L-000E is a DC input, two-channel optocoupler designed for reliable signal isolation in electronic systems. Featuring a surface mount SOIC package and eight-pin configuration, this optocoupler fits efficiently on densely populated PCBs and supports automated assembly. It provides high isolation voltage of 3.75 kVrms, enabling safe electrical separation between input and output circuits, particularly in industrial and laboratory applications where safety and signal integrity are crucial.

Each channel operates with a maximum forward voltage of 1.7V and supports up to 50mA input current, making the device suitable for low-power digital logic interfacing. The optocoupler is specially designed for DC input signals and offers a logic output, ensuring accurate signal reproduction and isolation from noise or surges. The minimum and maximum current transfer ratios (19% to 50%) guarantee consistent performance and reliable operation across varied system requirements.

Its surface mount SOIC package simplifies integration into modern electronics, and tape & reel packaging streamlines production in high-volume automated environments. The two optically isolated channels allow simultaneous transmission of independent signals, beneficial in multiplexed data acquisition, switching systems, and signal processing modules. The operating temperature range from -55°C to 100°C makes it robust for use in challenging industrial conditions and high-reliability settings.

Broadcom HCPL-053L-000E is compliant with major safety standards including CSA, VDE 0884, and UL 1577, enhancing confidence in its suitability for industrial, laboratory, and commercial projects. It does not meet automotive standards, focusing instead on critical environments such as manufacturing automation, control panels, instrumentation, and laboratory equipment.

Typical use cases include industrial automation systems, laboratory equipment, signal acquisition devices, and electronic control circuits where isolation, signal fidelity, and compact design are essential. The optocoupler is a key component for designers seeking robust, compact, and standards-compliant solutions for signal isolation.
