DPC816D-B-TU-V

Overview

The DPC816D-B-TU-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an NPN phototransistor output housed in a DIP-4 through-hole package. Key electrical specifications include a maximum collector-emitter voltage of 80 V, a maximum collector current of 30 mA, and an isolation voltage of 5000 Vrms. The device operates with a forward current of 5 mA and exhibits a typical rise/fall time of 18 µs. Current transfer ratio ranges from 130% to 260%, with a power dissipation rating of 200 mW across an operating temperature range of -55°C to +110°C.

Feature Summary

• Provides high-voltage isolation capability via 5000 Vrms insulation voltage for safe signal transmission between circuits.
• Delivers fast switching performance with symmetric 18 µs rise and fall times suitable for digital signal applications.
• Offers wide operational stability within an extended industrial temperature range from -55°C to +110°C.

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission in microprocessor-based interfaces
• Power supply feedback loops

Procurement Notes

Verify the specific suffix TU-V against the manufacturer's latest datasheet to confirm packaging format and compliance status. Ensure the DIP-4 through-hole configuration matches your PCB layout requirements. Cross-reference the CTR bin (B) with circuit design constraints to guarantee adequate noise margin. Confirm RoHS compliance details directly with the supplier documentation before finalizing procurement orders.

Selection Notes

Select this component when an 80 V collector-emitter voltage rating is required for medium-voltage isolation applications. The 130–260% CTR range provides sufficient gain for standard logic interfacing without excessive drive current. Consider the 18 µs switching speed as a limiting factor for high-frequency data transmission compared to faster logic output optocouplers.

Part Context

This part belongs to the DPC816 series of transistor output optocouplers produced by Diodes Incorporated. The series utilizes a standard DIP-4 package for through-hole mounting. The 'B' suffix typically denotes a specific Current Transfer Ratio binning category, distinguishing it from other variants like the D or Y series which may offer different CTR ranges.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with generic PC816 equivalents only if electrical parameters such as CTR and voltage ratings align precisely with the DPC816D-B-TU-V specifications.
