Product details
Overview
BC856S E6433 from Nexperia is a dual PNP silicon small-signal transistor array in SOT363 (SC74) package, configured as two galvanically isolated transistors with matched characteristics for AF input and driver stages. It delivers VCEO = 65 V, hFE = 200–630 (at IC = 2 mA), VCE(sat) ≤ 250 mV (IC = 10 mA, IB = 0.5 mA), and operates up to Tj = 150 °C in automotive-grade AEC-Q101-qualified applications.
For engineers reviewing the BC856S E6433 datasheet, BC856S E6433 pinout, BC856S E6433 application, or BC856S E6433 equivalent, key selection criteria include dual PNP matching tolerance, low VCE(sat) for efficient switching, high hFE stability across temperature, and RoHS-compliant SOT363 thermal performance in space-constrained analog driver circuits.
Technical Context
This dual-transistor array integrates two electrically isolated PNP BJTs on a single die with tightly controlled parameter matching-critical for differential pair amplifiers and complementary driver stages. Its design supports DC-coupled AF signal paths with guaranteed hFE ≥ 200 at IC = 10 µA and ≥ 290 at IC = 2 mA, enabling stable biasing without external trimming.
The device uses epitaxial base technology to achieve fT = 250 MHz and low Ccb = 1.5 pF, supporting high-frequency gain stability in preamplifier inputs. Thermal resistance RthJS ≤ 140 K/W ensures reliable operation under pulsed loads up to 200 mA with D < 2% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - Maximum collector-emitter voltage before breakdown in common-emitter configuration; enables use in 48 V rail systems with safety margin. |
| hFE (min) | 200 @ IC = 10 µA - Ensures predictable current amplification in low-bias input stages without thermal runaway risk. |
| VCE(sat) | 250 mV max @ IC = 10 mA, IB = 0.5 mA - Minimizes power loss and self-heating in linear driver applications. |
| fT | 250 MHz - Supports stable small-signal gain up to audio band upper limit (20 kHz) with >10× bandwidth margin. |
| RthJS | ≤140 K/W - Enables 250 mW dissipation at junction-to-solder-point interface; critical for PCB layout thermal relief design. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronics including HTOL, TC, and HTRB. |
Pinout & Package
SOT363 (SC74) surface-mount package: 6-pin, 2.1 mm × 2.0 mm footprint, 0.65 mm pitch, gull-wing leads, RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (E1) | Emitter of TR1 | Low-impedance current sink node for first transistor; tied to local ground reference in emitter-follower configurations. |
| 2 (B1) | Base of TR1 | High-impedance control input; requires current-limited drive to avoid saturation delay in switching mode. |
| 3 (C2) | Collector of TR2 | Active load node for second transistor; connects to supply rail in common-emitter amplifier topologies. |
| 4 (E2) | Emitter of TR2 | Independent emitter terminal enabling dual biasing schemes; allows separate emitter degeneration resistors per channel. |
| 5 (B2) | Base of TR2 | Isolated control path for second transistor; supports differential input or push-pull driver pairing. |
| 6 (C1) | Collector of TR1 | Main output node for TR1; designed for direct connection to load or next-stage base without level-shifting. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP transistor array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC857S E6433 | VCEO = 45 V (vs. 65 V); hFE min = 125 @ IC = 2 mA | Limited to ≤36 V systems; lower gain reduces loop stability margin in high-gain preamps | Select when lower voltage rating suffices and cost optimization is prioritized over headroom. |
| MBT3906DW1T1G | hFE = 100–300 (wider spread); RthJS = 200 K/W (higher thermal resistance) | Requires larger copper pour for same power dissipation; less suitable for high-density automotive PCBs | Choose only if legacy design compatibility mandates ON Semiconductor footprint. |
Compared with BC856S E6433, BC857S offers reduced voltage capability but identical packaging and pinout, while MBT3906DW1T1G trades matching precision and thermal efficiency for broader vendor availability-making BC856S optimal for AEC-Q101-critical, high-reliability dual-PNP functions.

FAQ
What is the maximum continuous collector current per transistor in BC856S E6433?
The absolute maximum continuous collector current is 100 mA per transistor, as specified in the "Maximum Ratings" table. This rating assumes TS ≤ 115 °C and applies to steady-state DC operation-not pulsed conditions. Exceeding this value risks thermal runaway due to the device's negative temperature coefficient of VBE.
Does BC856S E6433 support lead-free reflow soldering per JEDEC J-STD-020?
Yes, BC856S E6433 is qualified for lead-free reflow soldering with a peak temperature of 260 °C (per JEDEC J-STD-020D), enabled by its matte tin-plated gull-wing leads and SOT363 package construction. The device passes MSL Level 1 classification with unlimited floor life when stored at ≤30 °C/60% RH.
How does the dual-transistor isolation benefit circuit design?
The galvanic isolation between TR1 and TR2 eliminates substrate coupling and shared base-collector capacitance, enabling true differential operation without crosstalk-induced phase error. This is essential in precision current mirrors and balanced amplifier topologies where mismatched parasitics degrade CMRR above 10 kHz.
Can BC856S E6433 replace BC846B in single-transistor applications?
No-BC856S E6433 is a dual PNP array in SOT363, while BC846B is a single NPN transistor in SOT23. Pinout, polarity, and channel count are incompatible. For single-PNP replacement, BC856B (SOT23) is the functionally aligned part; BC856S serves only where dual, matched PNP topology is required.
