Product details
Overview
BC846BS-QF from Nexperia is a dual NPN general-purpose transistor pair in SOT363-3 (TSSOP6) package, rated for 65 V VCEO, 100 mA IC, and 200–450 hFE at 2 mA/5 V; designed for space-constrained automotive signal switching and amplification where matched gain and low mutual interference are required.
For engineers reviewing the BC846BS-QF datasheet, BC846BS-QF pinout, BC846BS-QF application, or BC846BS-QF equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating curves, per-transistor saturation voltages, and precise TSSOP6 terminal mapping - all critical for automotive PCB layout and reliability validation.
Technical Context
This dual NPN transistor integrates two electrically isolated silicon epitaxial planar devices in a single ultra-small surface-mount package. Each transistor supports VCEO = 65 V, IC = 100 mA continuous, and exhibits tightly matched DC current gain (hFE = 200–450 at 2 mA/5 V), enabling consistent biasing in differential or push-pull configurations without external trimming.
The device features low collector capacitance (Cc = 1.9 pF at 10 V), low VCE(sat) (200 mV typ. at 100 mA/5 mA), and qualified operation from −55 °C to +150 °C ambient, with junction temperature limited to 150 °C. Its Rth(j-a) = 416 K/W (per device on FR4) defines thermal limits under sustained load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V maximum collector-emitter voltage per transistor - sets safe operating voltage ceiling for 12 V/24 V automotive rail switching |
| IC | 100 mA continuous collector current per transistor - supports medium-current digital logic interfacing and sensor driver stages |
| hFE | 200–450 at VCE = 5 V, IC = 2 mA - enables predictable base drive sizing and stable small-signal amplification |
| VCE(sat) | 200 mV typical at IC = 100 mA, IB = 5 mA - minimizes conduction loss and self-heating in saturated switch applications |
| Cc | 1.9 pF at VCB = 10 V - reduces high-frequency signal coupling and improves bandwidth in RF-adjacent analog stages |
| Rth(j-a) | 416 K/W per device on FR4 PCB - determines maximum power dissipation (300 mW) before thermal shutdown at 25 °C ambient |
| AEC-Q101 | Qualified per Automotive Electronics Council stress test standard - validates suitability for under-hood and infotainment ECU use |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mounted package: 1.35 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height, with exposed pad not present; optimized for reflow soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Low-impedance current sink node for first transistor; connects directly to ground or emitter resistor in common-emitter configuration |
| 2 | Base of TR1 | Control input for TR1; requires current-limited drive (e.g., 5 mA max) to achieve full saturation |
| 3 | Collector of TR2 | High-side output node for second transistor; routed to load or next stage with minimal trace inductance |
| 4 | Emitter of TR2 | Independent emitter reference for TR2; allows separate biasing or current sensing without cross-coupling to TR1 |
| 5 | Base of TR2 | Isolated control input for TR2; no shared base path ensures zero functional interaction between transistors |
| 6 | Collector of TR1 | Primary output node for TR1; used in switching, amplification, or current mirror topologies with defined VCE headroom |
Key Features
| Feature | Design Value |
|---|---|
| Closely matched hFE | Both transistors exhibit 200–450 hFE at identical test conditions - eliminates gain mismatch in differential pairs or current mirrors |
| No mutual interference | Electrically isolated die structure with separate emitter/base/collector terminals - prevents crosstalk in timing-critical or noise-sensitive circuits |
| Low VCE(sat) | 200 mV typical at 100 mA/5 mA drive - reduces power loss by >40% versus standard general-purpose transistors at same current |
| AEC-Q101 qualification | Validated for automotive temperature cycling, HTRB, ESD, and mechanical shock - meets OEM requirements for engine control and body electronics |
| Reduced board space | Dual-transistor integration in 2.2 mm × 1.35 mm footprint - replaces two discrete SOT23 devices, saving ≥35% PCB area and assembly steps |
Applications
| Automotive Door Module Switching | Infotainment System Audio Preamp |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BS-Q | Higher hFE range (300–630), same VCEO/IC, identical SOT363-3 package and pinout | Better suited for low-base-drive applications (e.g., microcontroller GPIO direct drive); slightly higher leakage at 150 °C | Select when base current budget is constrained and gain consistency at low IC (<1 mA) is prioritized over absolute VCE(sat) minimum |
| MBT3904DW1T1G | Lower VCEO (40 V), higher VCE(sat) (300 mV typ.), non-AEC-Q101, SOT-363 package with identical pinning | Limited to 12 V systems only; unsuitable for under-hood environments requiring extended temperature or reliability validation | Choose for cost-sensitive consumer-grade designs where automotive qualification and 65 V headroom are unnecessary |
Compared with BC846BS-QF, BC847BS-Q offers higher gain for reduced base drive but marginally lower thermal robustness, while MBT3904DW1T1G sacrifices automotive qualification and voltage rating for lower unit cost in non-critical applications.

FAQ
What is the maximum allowable junction temperature for BC846BS-QF?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in IEC 60134 limiting values. Operation above this threshold risks permanent parametric shift or failure. Derating is required above 25 °C ambient: total device power must be reduced by 2.4 mW/°C beyond 25 °C, per the 416 K/W Rth(j-a) curve.
Can BC846BS-QF replace two discrete BC846B transistors in an existing design?
Yes - BC846BS-QF provides identical per-transistor specifications (VCEO = 65 V, IC = 100 mA, hFE = 200–450) in a single SOT363-3 package with pin-compatible mapping to dual SOT23 layouts. No circuit redesign is needed, though PCB footprint and thermal relief must match the TSSOP6 outline and solder paste stencil.
Does BC846BS-QF support wave soldering?
Yes - Nexperia provides dedicated wave soldering footprint data (Fig. 13) with 5.3 mm × 2.45 mm solder land dimensions and preferred transport direction. The device is qualified for both reflow (per IPC-J-STD-020) and wave processes, provided solder mask clearance and thermal mass balance meet the specified 0.3 mm solder resist margin.
How does the "Q" suffix in BC846BS-QF relate to automotive qualification?
The "Q" suffix denotes full AEC-Q101 qualification per Stress Test Qualification for Discrete Semiconductors, including HTGB, HTRB, TC, AC/DC life tests, and ESD (HBM ≥ 2 kV). This is distinct from standard commercial versions (e.g., BC846BS) and confirms suitability for automotive powertrain, chassis, and body electronics per OEM requirements.
