DPC816W-A-TU

Overview

The DPC816W-A-TU is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an NPN phototransistor output with a maximum collector-emitter voltage of 350 V and a continuous collector current rating of 50 mA. The device provides high isolation capability with an insulation voltage of 5000 Vrms. Electrical characteristics include a forward current of 60 mA, a forward voltage of 1.2 V, and a typical current transfer ratio of 50%. Switching performance is defined by rise and fall times of 18 µs each. The component operates within a temperature range of -55°C to +110°C and is housed in an MDIP-4 package.

Feature Summary

• Provides galvanic isolation between input and output circuits using optical transmission.
• Features a high-voltage NPN phototransistor output suitable for switching applications.
• Offers robust electrical isolation with a 5000 Vrms insulation rating.

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops
• Solid-state relay driver circuits

Procurement Notes

Verify the specific suffix and packaging configuration against official Diodes Incorporated documentation before procurement. Ensure that the MDIP-4 through-hole package aligns with the target PCB layout requirements. Confirm compliance with RoHS directives as specified in the manufacturer's datasheet. Cross-reference the part number with authorized distributors to ensure authenticity and traceability. Check for any recent product change notices that may affect specifications or availability.

Selection Notes

Select this component when high voltage isolation and moderate speed switching are required. The 350 V collector-emitter voltage makes it suitable for higher voltage side applications compared to standard 80 V variants. Consider the 60 mA forward current requirement for the LED input circuit design. Evaluate the thermal management needs given the 200 mW power dissipation rating. Compare switching speeds if faster response times are critical for the application.

Part Context

This part belongs to the DPC series of transistor output optocouplers from Diodes Incorporated. It shares functional similarities with other models like the DPC816D but offers distinct voltage ratings and package options. The series is designed for general-purpose isolation tasks in industrial and consumer electronics. It complements the company's portfolio of signal conditioning and protection devices.

Replacement Considerations

Direct substitutes may include other single-channel transistor output optocouplers with similar voltage and current ratings. Verify pin compatibility and package dimensions when considering alternatives. Check if replacement parts meet the same insulation voltage and current transfer ratio specifications. Ensure that the alternative device supports the required operating temperature range.
