BCW61E6384HTMA1

Overview

The BCW61E6384HTMA1 is a single NPN bipolar junction transistor (BJT) manufactured by Infineon Technologies. It is housed in a surface-mount SOT-23 package, designed for general-purpose switching and amplification applications. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 100 mA. With a DC current gain (hFE) range typically between 110 and 800 at a collector current of 2 mA, it offers high sensitivity for low-level signal control. The component is RoHS compliant and lead-free, suitable for automated assembly processes in consumer electronics and industrial control systems.

Feature Summary

• Single NPN configuration optimized for general-purpose switching tasks
• Compact SOT-23 surface-mount package for space-constrained designs

Procurement Notes

Verify the exact suffix HTMA1 to ensure correct tape-and-reel packaging specifications. Confirm RoHS compliance status with the supplier prior to order placement. Check for any regional supply restrictions or end-of-life notices directly from Infineon authorized distributors. Ensure storage conditions align with moisture sensitivity level requirements during handling.

Selection Notes

Select this component when a compact NPN switch with moderate current handling is required. Compare hFE ranges against specific circuit biasing needs to ensure reliable saturation. Consider thermal dissipation limits within the SOT-23 footprint for continuous operation. Evaluate alternative packages if higher power handling or different pinout configurations are necessary for the design.

Part Context

This part belongs to Infineon's standard discrete semiconductor portfolio, focusing on cost-effective, high-volume BJT solutions. It complements other small-signal transistors in the company's lineup, providing designers with reliable options for basic logic and analog switching functions across various consumer and industrial product categories.

Replacement Considerations

Direct substitutes include equivalent NPN transistors in SOT-23 packages with matching voltage and current ratings such as the BCW61 series variants. Verify pinout compatibility and electrical characteristics before substitution. Consult official replacement guides for cross-reference data.
