TBD62381AFWG,EL

Overview

The Toshiba TBD62381AFWG,EL is an eight-channel low-side DMOS transistor array designed for driving inductive loads. It operates with a supply voltage range of 4.5V to 5.5V and supports load voltages up to 50V. The device provides a maximum output current of 500mA per channel with an inverting configuration. Packaged in a 18-SOP surface-mount format, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates eight independent N-channel DMOS outputs for simultaneous control of multiple loads
• Features an inverting logic interface compatible with standard digital control signals
• Designed for robust operation with high surge current handling capabilities typical of DMOS technology

Applications

• Solenoid valve actuation in industrial automation systems
• Relay coil driving circuits for power distribution units
• Motor driver stages for small DC motors in home appliances
• LED matrix row/column drivers in display modules

Procurement Notes

Verify the specific suffix EL indicates the tape and reel packaging variant when ordering. Confirm the 18-SOP package dimensions match your PCB footprint requirements. Ensure the operating environment stays within the specified -40°C to +85°C thermal limits. Check RoHS compliance status if required by your manufacturing standards. Validate that the 50V load voltage rating exceeds your application's peak voltage.

Selection Notes

Select this component when eight isolated low-side switches are required in a compact surface-mount package. It is suitable for applications needing moderate current drive without external heat sinking under normal conditions. Consider the inverting logic requirement during schematic design. Compare against the TBD62387APG if through-hole mounting or different pinout compatibility is needed instead.

Part Context

This part belongs to the Toshiba TBD62381 series of DMOS transistor arrays. It serves as a direct replacement for legacy discrete transistor solutions requiring eight channels. The AF designation typically denotes the specific plastic encapsulation type within the broader product family. It complements other Toshiba drivers like the TBD62384 for similar functional requirements but different package styles.

Replacement Considerations

The TBD62387APG offers identical electrical performance but utilizes a 20-DIP through-hole package. The TBD62384APG provides similar functionality in a 18-PDIP package. Verify pin-to-pin compatibility before substituting these alternatives in existing designs.
