Description

SMBT3946DW1T1G is a dual bipolar-transistor device in a single SMBT (surface-mount) package. It contains two small-signal transistors in one package, designed for compact switching and amplification tasks on printed circuit boards. The “DW” indicates a dual-device configuration and “G” denotes RoHS-compliant packaging; the “1T1G” is a packaging/tape&reel code. Typical uses include signal switching, level shifting, and driver stages in consumer and industrial electronics. For exact specifications—maximum voltages and currents, DC gains (hFE), package/pinout, and thermal data—consult the manufacturer’s datasheet (e.g., the Diodes Inc/On Semiconductor SMBT family). If you want, I can pull up the datasheet and summarize the key ratings.

Features

SMBT3946DW1T1G is a dual-transistor device in a single package (SOT-23/6). Key features:
- Two NPN transistors in one package
- Vceo: 60 V per transistor
- Ic: up to ~0.3–0.5 A per transistor (depends on part)
- High current gain (hFE ranges broadly with Ic/temperature)
- Fast switching with low Vce(sat)
- Low leakage
- Pb-free, RoHS-compliant
- Packaging: Tape & Reel (T1G)
Note: exact electrical numbers (Ic, hFE, Vce(sat)) vary with temperature and Ic; consult the official datasheet for precise specs.

Package

SMBT3946DW1T1G uses an SMB package (DO-214AA).

Pinout

I can’t confirm the pin count and exact function without the datasheet. Do you want me to look up the SMBT3946DW1T1G datasheet and provide the precise pinout (pin count and per-pin function)?

Manufacturer

Manufacturer: ON Semiconductor (ON Semi).
Company type: American multinational semiconductor company that designs and sells a broad range of energy-efficient components—discrete devices (transistors/diodes), analog, logic, and power-management ICs for automotive, industrial, computing, and consumer applications.

Application

General-purpose transistor for switching and amplification in low-power circuits.
- Microcontroller interfaces and signal conditioning
- Relay and LED drivers, small-load switching
- Small-signal amplification (audio/RF preamps, biasing networks)
- Level shifting and pulse shaping
- Automotive/industrial control in low-current paths (RoHS-compliant in SOT-23)
