Présentation

Description

BC847BS-QX is a dual NPN transistor in a single surface-mount package from the BC847 family. It contains two independent NPN devices, making it suitable for general-purpose signal amplification and switching in compact circuits. The “QX” suffix denotes a specific packaging/lot variant (typically RoHS-compliant); consult the datasheet for exact package and lead finish.
Key figures (per transistor, typical): Vceo up to 45 V, Ic up to 100 mA, and hFE broadly in the 110–800 range depending on Ic and temperature. It’s designed for low-noise, medium-gain operation.
Package: usually a 6-pin SMD package (often SOT‑23‑6 style) housing both transistors.
Applications: general-purpose switching, buffering, level shifting, small-signal amplification, LED drivers, and other low-power analog/digital circuits.
For precise electrical limits, pinout, and packaging details, refer to the latest BC847BS-QX datasheet from the manufacturer.

Equivalent

Direct equivalents (dual NPN in the same SOT-23-6 package with similar ratings):
- BC846BS and BC848BS (siblings in the BC847 family)
- MMBT3904DW (dual NPN in SOT-23-6 from Onsemi/Diodes Inc)
Note: check Vce, Ic, hFE, and pinout in the datasheets for your exact replacement.

Features

BC847BS-QX features (highlights):
- Dual NPN transistors in one SOT-23-6 package (two independent devices)
- Ic up to 100 mA per transistor
- Voltage ratings: Vceo ~ 45 V; Vcbo ~ 60 V; VeBo ~ 5 V
- DC current gain (hFE): ~110–800 depending on Ic and temperature
- Low saturation voltage: Vce(sat) ≈ 0.2–0.4 V at typical drive
- Temperature range: -55°C to +125°C
- Pb-free / RoHS compliant; suitable for surface-mount designs
- Ideal for general-purpose switching and amplification in compact circuits
Note: “QX” indicates the specific variant/lot code; electricals shown are typical values per datasheet.

Pinout

Pin count: 6 pins.
Function: Dual NPN general‑purpose transistors in a single SOT-23‑6 package (two independent NPN transistors). Each transistor has its own E, B, C pins (no internal connection between the two transistors).
Typical pinout (one common arrangement): 1 = E1, 2 = B1, 3 = C1, 4 = E2, 5 = B2, 6 = C2.

Manufacturer

- Manufacturer: Nexperia.
- What kind of company: A Dutch multinational semiconductor company specializing in discrete components (transistors, diodes, protection devices) and related semiconductors for automotive, industrial, and consumer markets.

Application

BC847BS-QX is a dual NPN small-signal transistor in an SMD package. Typical application areas:
- General-purpose amplification and switching in low-power analog/digital circuits
- Dual/matched transistors for differential pairs, current mirrors, or push-pull drivers
- Signal buffering, level shifting, and preamplifier stages
- Low-side switching for LEDs, relays, and small loads
- Sensor interfaces and ADC front-ends (photodiodes, thermistors, etc.)
- Used in portable, consumer, automotive, and industrial electronics needing two small-signal transistors in one package.

Package

BC847BS-QX comes in a SOT-23-6 (SC-74A) package — a small 6-pin package containing a dual NPN transistor.
