DPC1018S-TR-V

Overview

The DPC1018S-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 for robust signal isolation. The device utilizes a phototransistor output with a collector-emitter saturation voltage of 200 mV maximum. Key electrical parameters include a maximum collector current of 30 mA, a collector-emitter voltage rating of 80 V, and a forward voltage of 1.25 V. The unit supports a forward current of 5 mA and offers a current transfer ratio ranging from 130% to 260%. Operating temperatures span from -55°C to +110°C.

Procurement Notes

Verify the specific suffix against official Diodes Incorporated documentation to confirm tape-and-reel quantities and packaging specifications. Ensure the component matches the required LSOP-4 footprint and thermal characteristics for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and moderate speed are required for single-channel applications. Consider the 80 V collector-emitter voltage limit and 30 mA current capacity against load requirements. Evaluate the 130% to 260% current transfer ratio range to ensure adequate gain for the driving circuitry within the specified temperature range.
