DPC1014S-TR

Overview

The DPC1014S-TR 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. The device utilizes a phototransistor output with a collector-emitter voltage of 80 V and a maximum collector current of 30 mA. Key electrical parameters include a forward current of 10 mA, a forward voltage of 1.25 V, and a power dissipation of 250 mW. The current transfer ratio ranges from 160% to 320%, with rise and fall times of 18 µs each. It operates within a temperature range of -55°C to +110°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using optical transmission.
• Features a compact LSOP-4 surface-mount package suitable for automated assembly processes.
• Utilizes a phototransistor output stage capable of handling specified collector currents and voltages.

Applications

• General-purpose signal isolation in industrial control systems
• Power supply feedback loops requiring galvanic isolation
• Microcontroller interface circuits for noise immunity

Procurement Notes

Verify the specific suffix and packaging configuration against official Diodes Incorporated documentation before procurement. Confirm that the LSOP-4 footprint matches the target PCB design. Ensure compliance with RoHS directives as indicated in the manufacturer's datasheet. Check availability status through authorized distributors, as stock levels may vary. Validate thermal performance requirements against the specified power dissipation limits.

Selection Notes

Select this component when a single-channel optocoupler with moderate speed and high isolation voltage is required. The 160% to 320% current transfer ratio ensures reliable switching characteristics. Consider the 80 V collector-emitter voltage rating for low-voltage output applications. The LSOP-4 package offers space efficiency compared to larger DIP packages. Verify that the 18 µs switching speed meets the system timing requirements.

Part Context

This part belongs to the DPC series of transistor output optocouplers from Diodes Incorporated. The series includes variants with different current transfer ratios and voltage ratings, such as the DPC1012S-TR. These components are designed for general-purpose isolation tasks where cost-effectiveness and reliability are prioritized. The TR suffix indicates tape and reel packaging for high-volume manufacturing.

Replacement Considerations

The DPC1012S-TR is a related variant within the same product family, offering similar packaging and isolation but with a lower current transfer ratio (63%-125%). Verify pinout compatibility and electrical parameter differences before substitution. No other direct substitute part numbers are confirmed in the provided data.
