Product details
Overview
BC846BS,135 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 isolated operation-used in compact signal switching and amplification stages of power management and interface circuits.
For engineers reviewing the BC846BS,135 datasheet, BC846BS,135 pinout, BC846BS,135 application, or BC846BS,135 equivalent, this device is selected for space-constrained dual-transistor functions requiring thermal isolation, low capacitance (Cc = 1.9 pF), and stable DC gain across temperature (−55 °C to 150 °C).
Technical Context
The BC846BS,135 integrates two electrically independent NPN transistors in a single 6-pin TSSOP package, with no mutual interference-enabling discrete dual-gain or push-pull configurations without crosstalk. Its matched hFE (200–450 at VCE = 5 V, IC = 2 mA) and low base-emitter saturation voltage (1.0 V max at IC = 100 mA) support precise current mirroring and low-loss switching.
Thermal design leverages per-device Ptot = 300 mW (FR4 PCB, 25 °C ambient) and Rth(j-a) = 416 K/W, while transient impedance curves confirm suitability for pulsed loads up to 200 mA peak (tp ≤ 1 ms). The 100 MHz fT supports audio-frequency amplification and digital switching up to ~10 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - Maximum safe collector-emitter voltage with base open; defines high-side switch headroom in 24–48 V systems. |
| IC | 100 mA continuous - Supports logic-level load driving (e.g., LEDs, small relays) without external heat sinking. |
| hFE | 200–450 at 2 mA - Enables predictable biasing in amplifier stages and ensures stable current gain across production lots. |
| VCE(sat) | 200 mV typ. at IC/IB = 20 - Minimizes conduction loss in saturated-switch applications, reducing power dissipation by >30% vs. standard BC847 variants. |
| Cc | 1.9 pF at VCB = 10 V - Limits high-frequency Miller effect, preserving bandwidth in RF-coupled preamp or oscillator buffer stages. |
| fT | 100 MHz at IC = 10 mA - Validates use in audio amplifiers and clocked digital interfaces up to 10 Mbps. |
| Rth(j-a) | 416 K/W (per device) - Allows thermal modeling on standard FR4 PCBs without copper pour; derates linearly above 25 °C ambient. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 1.35 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering with defined land pattern (2.35 mm × 2.65 mm solder pad area).
| 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., 5–10 kΩ series resistor) to avoid overdrive and ensure saturation. |
| 3 | Collector of TR2 | High-side output node for second transistor; routed to VCC or load supply in active-high switch topologies. |
| 4 | Emitter of TR2 | Independent return path for TR2; enables dual-emitter referencing without shared ground coupling. |
| 5 | Base of TR2 | Isolated control input for TR2; allows asynchronous switching or differential pair operation with no inter-transistor feedback. |
| 6 | Collector of TR1 | Primary output node for TR1; used in current mirror outputs, cascode stages, or as driver for downstream MOSFET gates. |
Key Features
| Feature | Design Value |
|---|---|
| Matched hFE between TR1/TR2 | Ensures <±10% gain variation in current mirrors or differential pairs-critical for precision analog front-ends. |
| No mutual interference | Electrically isolated die structure eliminates crosstalk; validated by zero coupling in VCE–IC curves under simultaneous switching. |
| Low collector capacitance (Cc) | 1.9 pF enables >50 MHz small-signal bandwidth in common-emitter amplifiers without neutralization. |
| Reduced board space | Dual-transistor integration cuts component count by 50% and saves ≥3.5 mm² vs. two discrete SOT23 devices. |
| Low VCE(sat) | 200 mV typical at full 100 mA load reduces power loss to <20 mW-ideal for battery-powered sensor nodes. |
Applications
| LED Driver Circuit | Current Mirror Reference |
|---|---|
|

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,135 | VCEO = 45 V (vs. 65 V); hFE min = 110 (vs. 200); same package and pinout. | Limited to ≤36 V systems; less suitable for industrial 48 V bus monitoring or automotive body-control modules. | Select when lower voltage rating is acceptable and higher gain consistency is not required. |
| MBT3904DW1T1G | SO-7 package (larger footprint); VCEO = 40 V; Cc = 4 pF (vs. 1.9 pF); no hFE matching spec. | Requires 2× PCB area; higher capacitance limits bandwidth to <30 MHz; unsuitable for precision current mirrors. | Choose only if SO-7 is mandated by legacy layout or thermal mass requirements exceed SOT363 capability. |
Compared with BC846BS,135, BC847BS,135 trades voltage headroom for marginally lower cost, while MBT3904DW1T1G sacrifices size, speed, and matching for broader distributor availability and higher thermal mass.

FAQ
What is the maximum junction temperature for BC846BS,135?
The absolute maximum junction temperature is 150 °C, verified per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of hFE and increased leakage. Derating begins at 25 °C ambient, with Ptot reduced by 2.4 mW/°C above 25 °C for the per-device rating of 300 mW.
Can BC846BS,135 be used in linear amplifier mode?
Yes-its fT of 100 MHz, low noise figure (3.1 dB at 1 kHz), and stable hFE across IC = 0.2–10 mA support Class-A audio preamplifier and sensor signal conditioning. Bias must maintain VCE ≥ 1 V to avoid saturation distortion and ensure linearity within ±0.5% THD.
Is the BC846BS,135 automotive qualified?
No-the device is not AEC-Q101 qualified and lacks automotive-specific testing or qualification documentation. Nexperia explicitly states non-automotive status in its legal disclaimers; use in automotive applications voids warranty and incurs full customer liability per section 14 of the datasheet.
How does the SOT363-3 package affect thermal performance compared to SOT363?
The SOT363-3 revision improves thermal resistance by optimizing internal leadframe geometry and mold compound, achieving Rth(j-a) = 416 K/W (per device) versus 450+ K/W in legacy SOT363. This 8% improvement enables 10–15 °C lower junction rise at 100 mA continuous load on standard FR4 PCBs.
