PS2733-1-A

Overview

The PS2733-1-A is a single-channel optoisolator manufactured by Renesas Electronics Corporation, featuring a Darlington transistor output. It provides an isolation voltage of 2500Vrms and supports a maximum output voltage of 350V. The device operates with a DC input type and has a typical forward voltage of 1.15V. Key electrical parameters include a maximum DC forward current of 50mA, a channel output current of 150mA, and a minimum current transfer ratio of 1500% at 1mA. The saturation voltage is rated at a maximum of 1V, with typical rise and fall times of 100µs each. It functions within a temperature range of -55°C to 100°C and is housed in a 4-SOP surface-mount package.

Feature Summary

High current transfer ratio capability for efficient signal transmission
Robust insulation performance suitable for demanding isolation applications
Wide operating temperature range for reliable industrial use

Applications

Industrial automation control systems
Power supply feedback loops
Solid-state relay drivers

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when high current drive capability via a Darlington output is required alongside strong galvanic isolation. Consider the 2500Vrms rating for safety-critical interfaces and verify that the 100µs switching speed meets the system timing constraints.

Part Context

This part belongs to the NEPOC series from Renesas, designed for general-purpose isolation tasks. It complements other devices in the portfolio by offering a balance between high gain and robust insulation in a compact surface-mount form factor.
