Product details
Overview
BC846BS/ZLX from Nexperia is a dual NPN general-purpose transistor pair in SOT363-3 (TSSOP6) package, rated for 65 V VCEO, 100 mA IC, and featuring matched hFE (200–450), low VCE(sat) (200 mV typ. at 100 mA/5 mA), and 1.9 pF collector capacitance - used in compact dual-switching and amplification circuits on space-constrained PCBs.
For engineers reviewing the BC846BS/ZLX datasheet, BC846BS/ZLX pinout, BC846BS/ZLX application, or BC846BS/ZLX equivalent, this device is selected for dual-channel signal switching where thermal isolation, gain matching, and low inter-transistor crosstalk are required in consumer, industrial, and communication interface designs.
Technical Context
The BC846BS/ZLX integrates two electrically isolated NPN transistors in a single TSSOP6 package with no mutual interference, enabling independent biasing and operation. Each transistor supports VCEO = 65 V, IC = 100 mA continuous, and operates across −55 °C to +150 °C ambient range with junction temperature up to 150 °C.
Its matched hFE (200–450 at VCE = 5 V, IC = 2 mA) and low Cc (1.9 pF) support stable small-signal amplification and fast switching in dual-gain-stage or push-pull configurations, while its 230 K/W Rth(j-sp) enables reliable thermal dissipation on standard FR4 boards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - Maximum safe collector-emitter voltage per transistor before breakdown; defines high-side switch headroom in 24–48 V systems. |
| IC | 100 mA - Continuous collector current rating per transistor; supports logic-level load switching and pre-driver stages. |
| hFE | 200–450 - DC current gain range at 2 mA collector current; enables predictable base drive sizing for consistent saturation. |
| VCE(sat) | 200 mV (typ.) at IC = 100 mA, IB = 5 mA - Low saturation voltage minimizes conduction loss and self-heating in switching applications. |
| Cc | 1.9 pF - Collector-base capacitance at 10 V; limits high-frequency roll-off and improves stability in RF-adjacent analog stages. |
| Ptot (per device) | 300 mW - Total power dissipation capability on FR4 PCB; allows dual-transistor operation without forced cooling. |
| fT | 100 MHz - Transition frequency at 10 mA; supports amplification and switching up to low-VHF band (e.g., 315/433 MHz ISM receivers). |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 1.3 mm × 2.2 mm footprint, 0.65 mm pitch, 0.9 mm max height, designed for reflow soldering with standard stencil-defined paste volume.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Low-impedance current sink node for first transistor; connects directly to ground or local return path. |
| 2 | Base of TR1 | Current-controlled input for TR1; requires ~5 mA base drive for full 100 mA saturation. |
| 3 | Collector of TR2 | High-side output node for second transistor; routed to load supply or pull-up rail. |
| 4 | Emitter of TR2 | Independent emitter reference for TR2; enables floating or split-bias configurations. |
| 5 | Base of TR2 | Isolated control input for TR2; decoupled from TR1's base for independent switching timing. |
| 6 | Collector of TR1 | Primary switched output; shares no internal connection with TR2 collector - eliminates cross-conduction risk. |
Key Features
| Feature | Design Value |
|---|---|
| No mutual interference | Electrically isolated die structure ensures TR1 and TR2 operate independently - critical for differential or anti-phase switching. |
| Closely matched hFE | Both transistors exhibit identical DC gain spread (200–450) under same test conditions - simplifies dual-amplifier bias network design. |
| Low VCE(sat) | 200 mV typical at full 100 mA load reduces power loss to ≤20 mW per transistor - extends battery life in portable devices. |
| Reduced board space | Dual-transistor integration cuts component count by one vs. discrete SOT23 pairs - saves ≥3.5 mm² PCB area per instance. |
| Low collector capacitance | 1.9 pF Cc minimizes Miller effect in switching edges - supports clean 10–20 ns rise/fall times in digital interfaces. |
Applications
| LED Driver Pair | Level-Shifting Interface |
|---|---|
|
Use Scenario: Driving dual-color LED indicators (e.g., status + fault) from a 3.3 V microcontroller GPIO with separate on/off control. IC Role / Device Role / Timing Role: Dual NPN switch providing isolated current sinking paths; each transistor controls one LED anode via common cathode configuration. Use Value: Eliminates need for two discrete SOT23 transistors and associated passives; matched hFE ensures uniform brightness across both LEDs at 5–20 mA. |
Use Scenario: Translating 1.8 V logic outputs to 5 V-tolerant inputs in mixed-voltage MCU peripherals (e.g., UART, SPI). IC Role / Device Role / Timing Role: Active-low level shifter using TR1 as input stage and TR2 as output pull-up driver in open-collector configuration. Use Value: 100 MHz fT and 200 mV VCE(sat) enable clean 10 Mbps signal translation with <5 ns propagation delay skew between channels. |
| Dual-Channel Sensor Signal Conditioning | Redundant Power Switch Control |
|
Use Scenario: Amplifying and buffering two analog sensor outputs (e.g., thermistor and photodiode) before ADC sampling in environmental monitoring nodes. IC Role / Device Role / Timing Role: Dual common-emitter amplifier stage with fixed 10 kΩ collector load and 1 MΩ base bias; each channel operates independently. Use Value: Matched hFE and low Cc ensure ≤0.5% gain mismatch and <10 kHz bandwidth error across both channels at 25 °C. |
Use Scenario: Controlling redundant 12 V power rails for safety-critical subsystems (e.g., motor enable and brake release) with independent enable signals. IC Role / Device Role / Timing Role: Dual high-side switch driver (with external P-MOSFETs) where TR1 and TR2 provide isolated gate turn-on pulses. Use Value: Electrical isolation between transistors prevents single-point failure propagation; 65 V VCEO supports 12 V rail with 4× safety margin. |
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 | Higher hFE range (300–630); otherwise identical pinout, ratings, and package. | Better suited for low-base-drive applications (e.g., weak GPIOs), but may require resistor recalibration for saturation. | Select when higher current gain is needed without changing layout or thermal design. |
| MMDT3904 | Same SOT363-3 package; lower VCEO (40 V), higher VCE(sat) (300 mV), and wider hFE spread (100–300). | Limited to ≤24 V systems; less suitable for precision gain-matched stages due to looser hFE tolerance. | Choose only for cost-sensitive, non-critical 3.3/5 V logic switching where voltage headroom is ample. |
Compared with BC846BS/ZLX, BC847BS offers higher gain for reduced base drive but identical thermal and switching performance, while MMDT3904 trades voltage rating and matching for lower unit cost - making BC846BS/ZLX optimal for 24–48 V dual-switching with tight gain control.

FAQ
What is the maximum operating temperature for BC846BS/ZLX?
The BC846BS/ZLX has a specified junction temperature limit of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance from junction to solder point is 230 K/W, allowing sustained operation at full 100 mA load on standard FR4 PCBs up to 100 °C ambient when derated per Figure 1.
Can BC846BS/ZLX replace two discrete BC846B transistors?
Yes - BC846BS/ZLX integrates two BC846B-equivalent NPN transistors in one SOT363-3 package with identical VCEO, IC, hFE, and VCE(sat) specs. Pin mapping differs (e.g., TR1 collector is pin 6, not pin 1), so PCB layout must follow Table 2 pinning, not SOT23 footprints.
Is BC846BS/ZLX suitable for automotive applications?
No - BC846BS/ZLX is not AEC-Q101 qualified and lacks automotive-specific testing or qualification documentation. Nexperia explicitly states in Section 14 that non-automotive qualified products are unsuitable for safety-critical or life-support systems, including automotive use.
What is the meaning of the marking code %E5 on BC846BS/ZLX?
The marking "%E5" on BC846BS/ZLX indicates the device type, where "%" is a placeholder for the manufacturing site code (e.g., "A" for Nijmegen, "B" for Bangkok) and "E5" is the standardized Nexperia type identifier for BC846BS - verified in Table 4 of the official product data sheet.
