DPC816L-A-TR

Overview

The DPC816L-A-TR is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an SLM-4 surface mount package and provides 5000 Vrms isolation voltage. The device operates with a forward current of 5 mA and a forward voltage of 1.25 V. Key electrical parameters include a collector-emitter voltage of 80 V, a maximum collector current of 30 mA, and a collector-emitter saturation voltage of 200 mV. The current transfer ratio ranges from 80% to 160%. Switching characteristics include rise and fall times of 18 µs. The component supports an operating temperature range from -55°C to +110°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes a phototransistor output for signal transmission
• Designed for surface mount assembly in compact layouts

Applications

• Data communication modules
• Personal electronics devices
• Automotive infotainment systems

Procurement Notes

Verify the specific suffix (e.g., -A-TR) against official Diodes Incorporated documentation to confirm current transfer ratio binning and tape-and-reel specifications. Ensure compatibility with required isolation voltage standards for the target application. Confirm availability status through authorized distributors as stock levels vary by region.

Selection Notes

Select this component when a single-channel optocoupler with moderate speed (18 µs) and high isolation (5000 Vrms) is required. The 80-160% CTR range suits applications needing reliable switching without excessive drive current. Consider the SLM-4 package size for PCB space constraints. Verify thermal management requirements given the -55°C to +110°C operating range.

Part Context

This part belongs to the DPC816L series of transistor output optocouplers from Diodes Incorporated. Variants such as DPC816L-B-TR and DPC816L-Y-TR offer different current transfer ratio bins while maintaining identical pinouts and electrical limits. The series is designed for general-purpose isolation in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other DPC816L variants like DPC816L-B-TR or DPC816L-C-TR if CTR binning differences are acceptable. Cross-brand replacements require matching 5000 Vrms isolation, 80 V Vceo, and SLM-4 package dimensions.
