DPC1017S-TR-V

Overview

The DPC1017S-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 insulation voltage between input and output. The device utilizes a phototransistor output with a minimum collector-emitter saturation voltage of 200 mV and supports a maximum collector current of 30 mA. Key electrical parameters include a forward voltage of 1.25 V at a forward current of 5 mA, a reverse voltage rating of 6 V, and a power dissipation capacity of 250 mW. Switching characteristics specify rise and fall times of 18 µs. The current transfer ratio ranges from 130% to 260%, ensuring reliable signal transmission across the isolation barrier within an operating temperature range of -55°C to +110°C.

Feature Summary

• Provides high-voltage galvanic isolation via a 5000 Vrms dielectric barrier between input and output circuits.
• Integrates a GaAs infrared LED emitter coupled with a silicon phototransistor for efficient optical signal transmission.
• Designed for surface-mount assembly in compact LSOP-4 packages to facilitate automated PCB placement.

Applications

• Industrial control systems requiring signal isolation between microcontrollers and power stages.
• Solid-state relay driver circuits for switching low-power loads.
• Communication interface isolation in data acquisition equipment.

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified partners. Confirm that the received units match the specific DPC1017S-TR-V marking and packaging specifications. Ensure compliance with RoHS directives and check for moisture sensitivity labeling prior to soldering. Validate datasheet revisions against the manufacturing date code to guarantee parameter consistency.

Selection Notes

Select this component when a single-channel phototransistor output is required with moderate current transfer ratios around 130-260%. The LSOP-4 form factor suits space-constrained designs needing 5000 Vrms isolation. Consider the 5 mA forward current requirement and 18 µs switching speed for timing-sensitive applications. Evaluate thermal management needs given the 250 mW power dissipation limit in enclosed environments.

Part Context

This part belongs to the DPC series of transistor output optocouplers from Diodes Incorporated. It shares the LSOP-4 package and basic isolation architecture with variants like DPC1012S-TR and DPC1018S-TR, which differ primarily in current transfer ratio specifications. The series targets general-purpose isolation needs in consumer and industrial electronics where compact size and reliable performance are prioritized.

Replacement Considerations

Direct substitutes include DPC1012S-TR and DPC1018S-TR from Diodes Incorporated, provided their specific current transfer ratios align with circuit requirements. Cross-manufacturer replacements must verify identical pinout configurations, insulation voltage ratings, and package dimensions to ensure mechanical and electrical compatibility without redesign.
