BD241A

Overview

The BD241A is an NPN silicon power transistor manufactured by STMicroelectronics using planar technology with a base island layout. It is part of the complementary BD24x series, paired with PNP types BD242A and BD242C. The device is characterized by exceptional high gain performance coupled with very low saturation voltage. The component is currently listed as obsolete.

Feature Summary

Manufactured using planar technology with a base island layout for enhanced thermal and electrical characteristics.
Delivers exceptional high gain performance suitable for power amplification applications.
Features very low saturation voltage to improve efficiency in switching and linear modes.

Applications

Power amplification circuits
Switching applications requiring high gain
Complementary push-pull configurations

Procurement Notes

Verify current availability status as the BD241A is officially listed as obsolete. Confirm that alternative components from the same family or newer generations meet all required electrical specifications before finalizing design integration. Check for any specific handling requirements associated with legacy stock.

Selection Notes

Select this component when designing circuits that require high gain and low saturation voltage in an NPN power transistor configuration. Consider the complementary BD242A for matched PNP applications. Ensure the design accounts for the component's obsolete status regarding long-term supply chain stability.

Part Context

The BD241A belongs to the BD24x family of complementary silicon power transistors. This series includes NPN (BD241) and PNP (BD242) variants available in A and C grades. These devices are designed for general-purpose power switching and amplification tasks within the bipolar transistor category.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Designers should consult official replacement guides or evaluate equivalent high-gain NPN power transistors from the manufacturer's current portfolio.
