Overview
The OR-357C-S-TP-G-(GK) is a single-channel phototransistor output optocoupler manufactured by Shenzhen Orient Components Co., Ltd. It features an infrared emitting diode coupled to an NPN silicon phototransistor in a compact SOP-4 package. The device provides electrical isolation with a rated insulation voltage of 5,000Vrms. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 35V and a maximum collector current (IC) of 50mA. The typical response time is specified at 4μs under standard operating conditions.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using an infrared LED and phototransistor pair.
- Utilizes a compact SOP-4 surface-mount package suitable for automated assembly and space-constrained designs.
- Offers fast switching performance with a typical response time of 4 microseconds.
Applications
- Computer peripheral interface circuits
- Instrumentation and measurement equipment signal isolation
- Automatic control systems requiring galvanic isolation
Procurement Notes
Verify the specific suffix codes against the manufacturer's latest datasheet to ensure correct packaging and binning specifications. Confirm that the SOP-4 footprint matches your PCB design requirements. Check for RoHS3 compliance status if required by your regulatory framework. Ensure the component meets the thermal management needs of your application environment.
Selection Notes
Select this component when a low-cost, general-purpose optocoupler with moderate speed and high isolation voltage is required. The SOP-4 package is ideal for applications where board space is limited. Consider the 50mA collector current limit when designing the load circuit. Verify that the 35V VCEO rating exceeds the maximum voltage present in the isolated output circuit during operation.
Part Context
This part belongs to the ORPC-817 series family of phototransistor optocouplers. These devices are designed as pin-compatible replacements for industry-standard 817-series components from manufacturers such as Avago, OnSemi, and Toshiba. The series is widely used in general-purpose isolation applications due to its balance of performance, reliability, and cost-effectiveness.
Replacement Considerations
The ORPC-817C is a direct functional equivalent. Other compatible parts include ORPC-817SC-TP-F and ORPC-817SC-TP-C from the same manufacturer. Verify pinout compatibility and electrical ratings before substituting with generic 817-type components from other suppliers.
