Product details
Overview
BC847BS/ZLX from Nexperia is a dual NPN general-purpose transistor pair in SOT363-3 (TSSOP6) package, rated for 45 V VCEO, 100 mA IC, and DC current gain (hFE) of 200–450 at 2 mA/5 V. It delivers low VCE(sat) (≤300 mV @ 100 mA/5 mA), low Cc (1.5 pF), and matched hFE across both transistors-enabling compact, interference-free dual-switching in space-constrained signal routing circuits.
For engineers reviewing the BC847BS/ZLX datasheet, BC847BS/ZLX pinout, BC847BS/ZLX application, or BC847BS/ZLX equivalent, key selection criteria include verified dual-transistor isolation, thermal derating on FR4 (Ptot = 250 mW standard / 400 mW enhanced pad), junction temperature limit (150 °C), and SOT363-3 footprint compatibility with automated reflow assembly.
Technical Context
The BC847BS/ZLX integrates two electrically isolated NPN transistors sharing a single SOT363-3 thermally optimized leadframe. Each transistor operates independently with no mutual coupling-confirmed by zero crosstalk in switching waveforms and separate base-emitter and collector-base breakdown ratings (V(BR)CEO = 45 V, V(BR)CBO = 50 V).
Its design targets low-power linear amplification and digital switching where tight hFE matching (200–450 typ.) and low saturation voltage (VCE(sat) ≤ 300 mV @ IC/IB = 20) reduce conduction loss and improve gain stability across temperature (−55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in switching applications. |
| IC | 100 mA continuous - Absolute max DC collector current per transistor; supports logic-level load switching up to ~100 mA. |
| hFE | 200–450 @ 2 mA/5 V - Tight DC current gain spread enables predictable biasing without individual trimming. |
| VCE(sat) | ≤300 mV @ IC = 100 mA, IB = 5 mA - Low saturation voltage minimizes power loss and self-heating in saturated-switch mode. |
| Cc | 1.5 pF @ VCB = 10 V - Low collector capacitance preserves high-frequency response (>100 MHz fT) in small-signal amplifiers. |
| Rth(j-a) | 568 K/W (standard FR4) - Thermal resistance determines junction temperature rise under steady-state operation. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 1.3 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering with defined land patterns (solder paste area: 0.5 mm × 0.5 mm for pins 2,4,5,6; 0.4 mm × 0.6 mm for pins 1,3).
| 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 ~0.65 V forward bias and sufficient IB to drive specified IC. |
| 3 | Collector of TR2 | High-side output node for second transistor; routed to VCC or load in active/saturation mode. |
| 4 | Emitter of TR2 | Current return path for TR2; electrically isolated from E1-enables independent bias networks. |
| 5 | Base of TR2 | Independent control input; no shared base connection ensures no cross-talk between switching events. |
| 6 | Collector of TR1 | Primary output node for TR1; used in amplifier stages or as switch output driving resistive or LED loads. |
Key Features
| Feature | Design Value |
|---|---|
| No mutual interference between transistors | Electrically isolated die structure confirmed by independent V(BR)CEO, V(BR)EBO, and leakage specs-enables true dual-channel operation without crosstalk. |
| Closely matched current gain | hFE spread ≤ 2.25× (200–450) across both transistors at same test conditions-reduces need for channel-specific bias compensation. |
| Low collector-emitter saturation voltage | VCE(sat) ≤ 300 mV at IC/IB = 20-cuts conduction loss by >40% vs. legacy general-purpose transistors (e.g., BC847B). |
| Reduced board space | Dual-transistor integration in 1.3 × 2.2 mm SOT363-3 saves ≥40% PCB area versus two discrete SOT23 devices with spacing. |
Applications
| LED Driver Circuit | Level-Shifting Interface |
|---|---|
|
Use Scenario: Driving dual-color indicator LEDs from 3.3 V microcontroller GPIOs with independent on/off control. IC Role / Device Role: Dual NPN switch providing isolated current sinking paths for red/green anodes tied to VCC. Use Value: Eliminates need for two separate SOT23 transistors and associated passives; matched hFE ensures consistent LED brightness across channels. |
Use Scenario: Translating 1.8 V logic signals to 5 V levels for legacy peripherals using open-collector topology. IC Role / Device Role: Dual NPN configured as active-low level shifter with pull-up resistors on collector outputs. Use Value: Independent transistor isolation prevents signal coupling; low VCE(sat) maintains <100 mV drop at 5 mA load-preserving noise margin. |
| Differential Pair Amplifier | Redundant Signal Switch |
|
Use Scenario: Building a low-noise, temperature-stable differential amplifier front-end for sensor signal conditioning. IC Role / Device Role: Matched NPN pair forming emitter-coupled active load with shared emitter resistor and independent collectors. Use Value: Factory-matched hFE and identical thermal characteristics minimize offset drift; low Cc supports bandwidth >100 MHz. |
Use Scenario: Providing fail-safe signal routing in industrial PLC I/O modules where primary and backup paths must be electrically isolated. IC Role / Device Role: Two independent NPN switches controlling redundant data lines-one active while the other remains off until fault detection. Use Value: Zero inter-transistor leakage (<5 µA ICBO at 150 °C) guarantees no unintended signal bleed between paths during standby. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN switching and amplification applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B, SOT23 (single) | Single NPN, same hFE range but no integrated dual topology; larger footprint (2.9 × 1.3 mm vs. 2.2 × 1.3 mm); higher Rth(j-a) (625 K/W). | Requires two devices + extra PCB area for dual-channel use; unsuitable where board space or thermal coupling matters. | Select when only one transistor is needed or when legacy SOT23 placement is fixed. |
| MBT3904DW1T1G (ON Semi) | Same SOT363-3 package, but hFE range wider (100–300); VCE(sat) higher (≤400 mV); Cc = 2.5 pF. | Lower gain consistency and higher capacitance reduce suitability for precision differential pairs or high-speed switching. | Select when cost sensitivity outweighs gain matching or RF performance requirements. |
Compared with BC847BS/ZLX, BC847B offers single-device flexibility but doubles layout area and thermal resistance, while MBT3904DW1T1G trades gain uniformity and low capacitance for broader availability-making BC847BS/ZLX optimal for space-constrained, matched dual-channel designs.

FAQ
What is the maximum allowable junction temperature for BC847BS/ZLX?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in IEC 60134 limiting values. Operation above this threshold risks permanent degradation of hFE and increased leakage. Derating is required above ambient temperatures of 25 °C-e.g., Ptot drops to 250 mW at Tamb = 25 °C on standard FR4, falling linearly to zero at 150 °C.
Can BC847BS/ZLX replace two separate BC847B transistors in a circuit?
Yes-provided the PCB layout uses the SOT363-3 footprint and pin assignments match (E1/B1/C1/E2/B2/C2). Electrical behavior is functionally equivalent per transistor, but BC847BS/ZLX adds benefits: guaranteed hFE matching, lower thermal resistance due to shared package mass, and elimination of inter-device layout variance.
Is BC847BS/ZLX qualified for automotive applications?
No-this device is not AEC-Q101 qualified and lacks automotive-grade screening, qualification testing, or extended temperature validation beyond the stated −65 °C to +150 °C storage range. Nexperia explicitly states non-automotive qualification in its legal disclaimers; use in safety-critical systems is prohibited.
What is the typical transition frequency (fT) and at what conditions is it measured?
The typical transition frequency is 100 MHz, measured at VCE = 5 V, IC = 10 mA, f = 100 MHz, and Tamb = 25 °C. This value reflects the frequency at which current gain drops to unity and confirms suitability for RF preamplifier or high-speed switching applications up to ~30 MHz practical bandwidth.
