BCX38CSTOB

Overview

The BCX38CSTOB is an NPN Darlington transistor manufactured by Diodes Incorporated, housed in a TO-92 compatible E-Line package. It features a maximum collector-emitter voltage of 60V and a continuous collector current of 800mA. The device supports a power dissipation of 1W and operates within a junction temperature range of -55°C to 200°C. DC current gain (hFE) is specified at a minimum of 10,000 under standard test conditions.

Feature Summary

• High current gain capability suitable for sensitive switching applications
• Robust thermal performance with extended junction temperature limits
• Standard through-hole mounting configuration for versatile integration

Applications

• General purpose switching circuits
• Driver stages for relays or motors
• Logic interface buffers

Procurement Notes

Verify the specific suffix 'STOB' against official manufacturer documentation to confirm exact packaging and tape-and-reel specifications. Ensure compliance with RoHS3 and REACH requirements as stated in the product family datasheet. Confirm availability and lead times directly with authorized distributors, as supply chain data varies by region and time.

Selection Notes

Select this component when high current gain is required for driving loads from low-current logic sources. The 60V rating and 800mA current capacity define its operational boundaries. Consider the TO-92 form factor for prototyping or low-volume production where surface-mount alternatives are not mandatory. Validate thermal management strategies for sustained operation near the 1W dissipation limit.

Part Context

This part belongs to the BCX38 series of NPN Darlington transistors from Diodes Incorporated. The series offers variants with different gain grades and packaging options, including standard TO-92 and E-Line formats. The BCX38C designation typically indicates a specific gain binning category within the broader product line.

Replacement Considerations

Check for direct substitutes such as BCX38C or BCX38CSTZ from the same manufacturer. Verify pinout compatibility and electrical parameter equivalence before substitution. Cross-reference with other manufacturers' Darlington transistors only if mechanical and electrical specs align precisely.
