BC847BT-7

Overview

The BC847BT-7 is an NPN small signal transistor manufactured by Diodes Incorporated, housed in a surface-mount SOT523 package. It features a collector current of 100 mA and a collector-emitter breakdown voltage exceeding 45 V. The device utilizes epitaxial planar die construction and offers a DC current gain (hFE) range of 200 to 450 at IC = 2 mA. Electrical characteristics include a collector-base breakdown voltage of 50 V, a power dissipation of 150 mW, and a transition frequency of 100 MHz. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

Ultra-small surface-mount SOT523 plastic package design
Epitaxial planar die construction for reliability
Totally lead-free and fully RoHS compliant
Halogen and antimony free "Green" device

Applications

General-purpose switching applications
Small signal amplification circuits
Low noise audio pre-amplifiers

Procurement Notes

Verify the specific ordering suffix matches the required packaging quantity and reel specifications. Confirm that the SOT523 package marking code corresponds to the intended gain bin selection. Ensure compliance with moisture sensitivity level requirements during storage and assembly processes. Check for automotive-compliant alternatives if AEC-Q101 standards are necessary for the target application environment.

Selection Notes

Select this component when a compact footprint is required for general-purpose NPN switching or amplification tasks. The BC847BT variant provides a moderate current gain suitable for standard logic interfacing and low-power analog stages. Consider the complementary MMBT3906T PNP transistor for push-pull configurations. Evaluate thermal resistance constraints given the limited power dissipation capability of the SOT523 package.

Part Context

This part belongs to the BC847AT, BT, CT series of 45V NPN small signal transistors. It serves as a surface-mount alternative to larger through-hole packages while maintaining similar electrical performance profiles. The series is designed for high-volume consumer electronics and portable devices where board space is constrained.
