TD62783AD

Overview

The TD62783AD is an 8-channel Darlington current driver in a SOP-18 package. It contains eight NPN Darlington pairs with common-anode clamp diodes for switching inductive loads. Each channel supports a single output current of -500 mA and an output voltage of 50 V. The device operates within a supply voltage range up to 50 V and an ambient temperature range of -40°C to 85°C. Input pins are positioned opposite to output pins to simplify board layout.

Feature Summary

• Monolithic high-voltage, high-current Darlington transistor arrays
• Integrated common-anode clamp diodes for inductive load protection
• Input pins placed opposite to output pins to simplify layout

Applications

• Relay drivers
• Stepper and DC brushed motor drivers
• Lamp drivers
• Display drivers
• Line drivers

Procurement Notes

Verify the specific SOP-18 package marking against the datasheet documentation. Confirm that the supplier provides the official HTC datasheet revision R1.0 dated June 2020. Ensure the component matches the active status listed in the ordering information section before finalizing procurement.

Selection Notes

Select this component when driving inductive loads requiring up to 500 mA per channel. The integrated clamp diodes eliminate external snubber requirements. Verify logic compatibility with input voltage levels. Consider paralleling channels if higher current capability than 500 mA is required for specific applications.

Part Context

This part belongs to the TD62783A series of Darlington arrays. The 'D' suffix specifically denotes the SOP-18 surface-mount package variant. Other variants include the DIP-18 package version designated as TD62783AN. Both share identical electrical characteristics and pin configurations.
