DPC816W-Y-TU-V

Transistor, Photovoltaic Output Optoisolators Overview

The DPC816W-Y-TU-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an NPN phototransistor output housed in a surface-mount MDIP-4 package. The device provides electrical isolation with a rated insulation voltage of 5000 Vrms. Key electrical parameters include a collector-emitter saturation voltage of 200 mV maximum, a forward voltage of 1.25 V typical, and a reverse voltage rating of 6 V. The unit supports a maximum collector current of 30 mA and operates within a temperature range of -55°C to +110°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-voltage isolation between input and output circuits via optical coupling.
• Utilizes an NPN phototransistor for digital signal transmission applications.
• Designed for through-hole mounting in compact MDIP-4 packages.

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal interfacing between microcontrollers and high-voltage loads

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'Y' corresponds to the required Current Transfer Ratio (CTR) binning of 150% to 300%, as defined in the official datasheet. Confirm that the MDIP-4 package dimensions align with the target PCB footprint. Ensure compliance with RoHS directives if applicable to the end-use environment. Cross-reference the manufacturer part number against authorized distributor catalogs to confirm authenticity and traceability before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a standard CTR range of 150% to 300% is sufficient for the application's noise margin requirements. The MDIP-4 package offers a balance between isolation creepage distance and board space efficiency compared to larger DIP variants. Consider the 18 µs rise and fall times for switching speed limitations in high-frequency digital interfaces. Evaluate the 5000 Vrms isolation rating against the system's working voltage and transient overvoltage specifications to ensure adequate safety margins.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the DPC816 series of transistor output optocouplers from Diodes Incorporated. The series includes variants with different CTR bins (A, Y) and package types (DIP, MDIP). The DPC816W-Y-TU-V specifically denotes the wide-body MDIP-4 package with the higher CTR bin, distinguishing it from lower CTR or standard DIP versions within the same product family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes within the same series include DPC816W-A-TU-V, which shares the MDIP-4 package but features a lower CTR range (100%-200%). Other compatible options may include generic 4-pin transistor output optocouplers with matching 5000 Vrms isolation and similar pinout configurations, provided CTR and switching speed requirements are met.
