DPC816W-C-TU

Overview

The DPC816W-C-TU is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an NPN phototransistor output and is housed in a 4-pin MDIP package designed for through-hole mounting. The device provides electrical isolation with a rated insulation voltage of 5000 Vrms. Key electrical specifications include a collector-emitter saturation voltage of 200 mV maximum, a collector current rating of 30 mA, and a collector-emitter voltage of 80 V. The input side operates with a forward current of 5 mA and a forward voltage of 1.25 V. The unit supports a wide operating temperature range from -55°C to +110°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Features fast switching performance with specified rise and fall times
• Designed for robust operation across extended industrial temperature ranges

Applications

• Industrial process control signal isolation
• Power supply feedback loop isolation
• Microcontroller interface isolation

Procurement Notes

Verify the specific suffix against official Diodes Incorporated documentation to confirm exact binning or testing criteria. Confirm package type and lead configuration match the target PCB footprint. Ensure compliance with relevant regional regulatory standards required for the final assembly. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability status.

Selection Notes

Select this component when high isolation voltage is required for low-speed digital signal transmission. The MDIP package suits applications requiring manual insertion or standard through-hole manufacturing processes. Consider the current transfer ratio requirements for the specific load driving the phototransistor. Verify that the 80 V collector-emitter voltage rating exceeds the maximum transient voltages present in the isolated circuit.

Part Context

This component belongs to the DPC816 series of transistor output optocouplers from Diodes Incorporated. The series is characterized by high reliability and consistent performance for general-purpose isolation tasks. Similar variants within the family may differ in packaging style, such as SMD options, or electrical characteristics like CTR bins. The DPC816W designation typically indicates the through-hole MDIP form factor.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify that substitute parts meet or exceed the 5000 Vrms insulation voltage requirement. Ensure the replacement maintains compatible input forward voltage and output current capabilities.
