BC847BTQ-7

Overview

The BC847BTQ-7 is an NPN small signal Bipolar Junction Transistor (BJT) manufactured by Diodes Incorporated. It utilizes epitaxial planar die construction and is housed in a SOT523 surface-mount package. The device is qualified to AEC-Q101 standards for automotive applications. Key electrical parameters include a collector-emitter voltage of 45V, a collector current of 100mA, and a power dissipation of 150mW. The DC current gain ranges from 200 to 450 at VCE=5V and IC=2mA. The transition frequency is 100MHz, with an operating temperature range of -55°C to +150°C.

Feature Summary

• Qualified to AEC-Q101 standards for high reliability in automotive environments
• Totally lead-free and fully RoHS compliant with halogen and antimony-free green compound
• Epitaxial planar die construction designed for stringent automotive requirements
• Ultra-small SOT523 surface mount package suitable for automated insertion

Applications

• General-purpose switching circuits

Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the 3,000-unit reel quantity and '1F' marking code as documented in the official datasheet. Confirm that the component meets the required PPAP capability if mandated by the specific automotive supply chain agreement. Ensure compliance with the defined moisture sensitivity level and soldering methods specified in the mechanical data section.

Selection Notes

Select this component when an NPN transistor with AEC-Q101 qualification is required for automotive designs. The SOT523 package offers space savings compared to standard SOT-23 variants. Consider the hFE range of 200-450 for biasing calculations. Verify thermal management needs against the 150mW dissipation limit and 833 °C/W thermal resistance under still air conditions on FR-4 PCBs.

Part Context

This part belongs to the BC847x series of general-purpose NPN transistors produced by Diodes Incorporated. While other manufacturers offer similar BC847B devices, the BTQ variant specifically denotes the SOT523 package and automotive qualification status. It serves as a compact replacement for larger packages in portable and automotive electronics where space constraints are critical.
