BCW70LT1G

Overview

The BCW70LT1G is a PNP silicon general-purpose transistor manufactured by onsemi. It features a maximum collector current of 100 mA and a collector-emitter voltage rating of 45 V. The device operates within a temperature range of -55°C to +150°C junction temperature. It utilizes an SOT-23-3 surface-mount package with a power dissipation capacity of 300 mW. The component exhibits a minimum DC current gain (hFE) of 215 at specified test conditions.

Feature Summary

• PNP epitaxial silicon construction for reliable switching performance
• High DC current gain suitable for low-level signal amplification
• Lead-free packaging compliant with environmental standards

Applications

• General purpose switching circuits
• Low-frequency amplification stages
• Driver applications for logic interfaces

Procurement Notes

Verify the specific datasheet revision and manufacturing origin before integration, as process changes may affect mechanical dimensions or wire bond materials. Confirm RoHS compliance status through official manufacturer declarations. Ensure the ordering suffix matches the required tape and reel specifications for automated assembly processes.

Selection Notes

Select this component for designs requiring a compact PNP solution in an SOT-23-3 footprint. Compare hFE ranges against circuit requirements to ensure adequate drive capability. Verify thermal management needs given the 300 mW power dissipation limit in small outline packages.

Part Context

This part belongs to the BCW70L series of general-purpose transistors from onsemi. It serves as a surface-mount alternative to larger through-hole packages while maintaining similar electrical characteristics. The series is designed for cost-effective mass production in consumer and industrial electronics.

Replacement Considerations

Compatible substitutes include BC857 variants and other PNP transistors in SOT-23-3 packages with matching voltage and current ratings. Verify pinout compatibility and hFE binning before substitution.
