BC849BLT1

Overview

The onsemi BC849BLT1 is a general-purpose NPN silicon transistor in the BC846ALT1 series, housed in an SOT-23 (TO-236) surface-mount package. It features a collector-emitter voltage of 30 V and a continuous collector current of 100 mA. The device provides a minimum DC current gain of 200 at 2 mA and 5 V, with a transition frequency of 100 MHz. Maximum power dissipation reaches 300 mW on an alumina substrate, operating within a junction temperature range of -55°C to +150°C.

Feature Summary

NPN epitaxial planar silicon design for general-purpose amplification
Moisture sensitivity level 1 with high electrostatic discharge protection ratings
Lead-free packaging compliant with environmental directives

Applications

General purpose amplifier applications
Switching circuits requiring low saturation voltage
Digital logic interface buffering

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and shipping quantity. Confirm RoHS compliance status and lead-free designation requirements for your assembly process. Ensure the component matches the exact electrical characteristics defined in the datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a 30 V NPN transistor with moderate current handling is required. The BC849B variant offers a guaranteed minimum hFE of 200, suitable for applications needing consistent amplification. Consider thermal constraints if operating near maximum power dissipation limits in confined spaces.

Part Context

This part belongs to the BC846ALT1 series, which includes various voltage and gain combinations like BC846, BC847, BC848, and BC850. All share the same SOT-23 footprint but differ in breakdown voltages and current gain ranges. This series is designated as a Preferred Device by the manufacturer for future use.
