DPC1012S-TR-V

Overview

The DPC1012S-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. The device utilizes an NPN phototransistor output with a collector-emitter voltage rating of 80 V and a maximum collector current of 30 mA. Key electrical parameters include a forward current of 10 mA, forward voltage of 1.25 V, and saturation voltage of 200 mV. The current transfer ratio ranges from 63% to 125%, 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 isolation capability for signal transmission between isolated circuits
• Utilizes a compact surface-mount LSOP-4 package for automated assembly integration
• Features robust phototransistor output suitable for digital switching applications

Applications

• General-purpose signal isolation in industrial control systems
• Interface circuits for microprocessor-based logic systems
• Power supply feedback loops requiring galvanic separation

Procurement Notes

Verify the specific suffix designation against manufacturer documentation to confirm tape-and-reel packaging quantities and handling specifications. Ensure that the ordering part number matches the exact electrical characteristics required for the design, as variations may exist within the product family. Cross-reference the datasheet revision date to confirm compliance with current safety standards and insulation ratings before finalizing procurement orders.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed requirements is needed. The 80 V collector-emitter voltage rating supports standard logic level interfacing. Consider the 18 µs switching time for application bandwidth limitations. Verify thermal management needs given the operating temperature range and power dissipation constraints inherent to the small outline package configuration.

Part Context

This component belongs to the DPC series of transistor output optocouplers from Diodes Incorporated. It shares the LSOP-4 form factor with related models such as the DPC1013S-TR-V and DPC1014S-TR-V, which offer different current transfer ratio ranges. The series is designed for cost-effective isolation in consumer and industrial electronics where space constraints and reliability are critical factors.
