DPC1014S-TR-V

Overview

The DPC1014S-TR-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an LSOP-4 surface-mount package and provides 5000 Vrms isolation voltage between input and output circuits. The device utilizes an NPN phototransistor output with a collector-emitter saturation voltage of 200 mV maximum. Key electrical parameters include a forward current of 10 mA, a forward voltage of 1.25 V, and a maximum collector current of 30 mA. The collector-emitter breakdown voltage is rated at 80 V. The unit exhibits a current transfer ratio ranging from 160% to 320%, with a rise time of 18 µs.

Feature Summary

• Provides high-voltage electrical isolation via 5000 Vrms dielectric barrier for noise immunity in signal transmission.
• Integrates an infrared emitting diode coupled directly to an NPN phototransistor for efficient optical-to-electrical conversion.
• Designed for compact surface-mount integration using the LSOP-4 package format.

Applications

• Industrial control systems requiring galvanic isolation
• Signal interfacing between microcontrollers and high-voltage loads
• Power supply feedback loops

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified suppliers. Confirm the LSOP-4 package marking matches official datasheet specifications. Ensure storage conditions comply with moisture sensitivity levels prior to reflow soldering. Validate that the specific tape-and-reel quantity aligns with production requirements. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed and high CTR is required. The 80 V collector-emitter voltage suits low-voltage switching applications. Compare against similar models like DPC1013S-TR-V if lower current transfer ratios are acceptable. Consider thermal management within the LSOP-4 footprint during PCB layout. Ensure the 10 mA forward current drive capability matches the source circuit limitations.

Part Context

This part belongs to the DPC series of transistor output optocouplers from Diodes Incorporated. It shares functional similarities with other members such as the DPC1013S-TR-V but differs in current transfer ratio specifications. The series targets general-purpose isolation needs in consumer and industrial electronics. The TR-V suffix indicates a specific tape-and-reel packaging configuration for automated assembly processes.
