Product details
Overview
BC846SH-QF from Nexperia is an AEC-Q101-qualified NPN/NPN general-purpose double transistor in SOT363 (SC-88) package, rated for 65 V VCEO, 100 mA IC, and 175 °C junction temperature, used for space-constrained automotive signal switching and amplification.
For engineers reviewing the BC846SH-QF datasheet, BC846SH-QF pinout, BC846SH-QF application, or BC846SH-QF equivalent, this dual-transistor device supports high-temperature automotive subsystems requiring matched hFE, low VCEsat, and mutual interference isolation between channels.
Technical Context
This dual NPN transistor integrates two electrically isolated, closely matched gain transistors in a single TSSOP6 footprint, enabling compact dual-channel switching without crosstalk. Each channel supports 65 V collector-emitter breakdown and operates up to 175 °C junction temperature.
It delivers hFE = 110 (VCE = 5 V, IC = 2 mA), VCEsat = 200–300 mV (IC = 100 mA, IB = 5 mA), and Cc = 1.2 pF (VCB = 10 V), making it suitable for low-power, high-reliability linear and switching functions in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - Maximum safe collector-emitter voltage per transistor under open-base conditions. |
| IC | 100 mA - Continuous DC collector current rating per transistor at Tamb ≤ 25 °C. |
| hFE | 110 - DC current gain at VCE = 5 V, IC = 2 mA, Tamb = 25 °C; enables predictable biasing in amplifier stages. |
| VCEsat | 200–300 mV - Low saturation voltage at IC = 100 mA / IB = 5 mA; minimizes conduction loss in switching applications. |
| Cc | 1.2 pF - Collector capacitance at VCB = 10 V; supports stable high-frequency operation up to 100 MHz fT. |
| Tj max | 175 °C - Maximum junction temperature; qualified for under-hood automotive use with no derating required below this limit. |
| Rth(j-a) (per device) | 375 K/W - Thermal resistance from junction to ambient on FR4 PCB; defines power dissipation limits in real board layouts. |
Pinout & Package
Package: SOT363 (TSSOP6), 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, surface-mount plastic package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E1 | Emitter of transistor TR1 - primary current sink node for first NPN channel. |
| 2 | B1 | Base of transistor TR1 - control input for first NPN channel; requires ~0.7 V forward bias. |
| 3 | C2 | Collector of transistor TR2 - primary current source node for second NPN channel. |
| 4 | E2 | Emitter of transistor TR2 - current sink node for second NPN channel; electrically isolated from E1. |
| 5 | B2 | Base of transistor TR2 - independent control input for second NPN channel; no coupling to B1. |
| 6 | C1 | Collector of transistor TR1 - current source node for first NPN channel; arranged diagonally opposite E1 for layout symmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Closely matched hFE | Enables balanced dual-channel gain in differential or push-pull configurations without external trimming. |
| No mutual interference | Electrically isolated transistor die structure prevents signal coupling or thermal crosstalk between TR1 and TR2. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, temperature cycling, and ESD robustness per JESD47. |
| Low VCEsat (200–300 mV) | Reduces power loss and self-heating during saturated switching, critical for thermally constrained modules. |
| High-temperature operation (175 °C) | Supports placement near heat sources (e.g., power converters, motor drivers) without derating or thermal shielding. |
Applications
| Automotive Body Control Module | Industrial Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847SH-Q | Higher hFE range (200–450 vs. 110 min); same VCEO, IC, package, and AEC-Q101 qualification. | Better suited for low-base-drive applications (e.g., microcontroller GPIO direct drive) but less ideal where tight hFE matching is required. | Select BC847SH-Q when higher gain and lower base current are prioritized over inter-channel matching. |
| MBT3904DW1T1G | Same dual NPN topology and SOT363 package, but not AEC-Q101 qualified; hFE min = 100, VCEO = 40 V. | Limited to non-automotive industrial or consumer use; unsuitable for under-hood or safety-critical systems. | Choose MBT3904DW1T1G only for cost-sensitive, non-automotive designs where 40 V rating suffices. |
Compared with BC846SH-QF, BC847SH-Q offers higher gain flexibility but looser matching, while MBT3904DW1T1G sacrifices automotive qualification and voltage headroom for lower cost-making BC846SH-QF optimal for AEC-compliant dual-switching where matched performance and 65 V margin are essential.

FAQ
What is the maximum continuous collector current per transistor in BC846SH-QF?
The BC846SH-QF supports 100 mA continuous collector current per transistor at Tamb ≤ 25 °C, with 200 mA peak capability for short pulses (tp ≤ 1 ms). Derating applies above 25 °C per the 375 K/W per-device Rth(j-a) curve shown in Figure 1.
Is BC846SH-QF pin-compatible with BC847SH-Q?
Yes - BC846SH-QF and BC847SH-Q share identical SOT363 (TSSOP6) pinout, mechanical dimensions, and thermal footprint. Both follow the same 1=E1, 2=B1, 3=C2, 4=E2, 5=B2, 6=C1 assignment, enabling drop-in replacement where electrical specs align.
Does BC846SH-QF require external protection when driving inductive loads?
While BC846SH-QF withstands 80 V VCBO and 65 V VCEO, flyback voltage spikes exceeding these ratings can occur with unclamped inductive loads. Use external clamping (e.g., reverse-biased diode across coil) for reliable operation in relay or solenoid drive applications.
How does the 175 °C junction rating impact PCB layout?
The 175 °C Tj rating allows operation in high-ambient zones, but thermal design must still maintain Tj ≤ 175 °C. Use minimum 35 µm copper on FR4 with standard SOT363 solder footprint (Fig. 12), and avoid enclosing the device under conformal coating unless airflow or thermal vias compensate for reduced convection.
