BC846BT TR PBFREE

Overview

The BC846BT TR PBFREE is an NPN single bipolar junction transistor manufactured by Central Semiconductor Corp. It features a collector-emitter breakdown voltage of 65 V and a maximum continuous collector current of 100 mA. The device operates with a transition frequency of 100 MHz and supports a power dissipation of 250 mW. It utilizes the SOT-523 surface-mount package (SC-89/SOT-490). DC current gain (hFE) is specified at a minimum of 200 when tested at 2 mA base current and 5 V collector-emitter voltage. The saturation voltage is limited to 400 mV under specific drive conditions, and the collector cutoff current remains below 15 nA.

Feature Summary

• Ultra-small SC-89 plastic surface-mount encapsulation for compact circuit layouts
• High DC current gain performance suitable for general-purpose amplification
• Low collector cutoff current characteristics for efficient switching applications

Applications

• General purpose switching circuits in portable equipment
• Small signal amplification stages
• Low voltage logic interface applications

Procurement Notes

Verify the exact suffix against the manufacturer's latest documentation to confirm packaging type and RoHS compliance status. Ensure the ordering code matches the required reel or cut tape format. Cross-reference the component marking with official datasheets to distinguish between similar variants within the BC846 family. Confirm that the batch date codes align with project requirements before finalizing procurement orders.

Selection Notes

Select this component when a small footprint NPN transistor is required for low-power signal processing. The SOT-523 package offers space savings compared to standard SOT-23 alternatives while maintaining comparable electrical performance. Consider the 65 V rating for moderate voltage switching tasks. Verify thermal management needs as the 250 mW dissipation limit applies to specific mounting conditions.

Part Context

This part belongs to the BC846 series of NPN general-purpose transistors produced by Central Semiconductor Corp. The series includes various gain bins and packaging options designed for consumer electronics and industrial control systems. The BC846BT variant specifically denotes a particular gain classification within the broader product line, optimized for consistent performance in mass-produced devices.

Replacement Considerations

Direct substitutes include BC846B from other manufacturers such as Diotec or Nexperia, provided they utilize compatible pinouts and meet the 65 V / 100 mA specifications. Verify package compatibility, as some equivalents may use SOT-23 instead of SOT-523.
