Product details
Overview
BC847SE6433BTMA1 from Nexperia is a dual NPN silicon small-signal transistor array in SOT363 (SC74) package, featuring two galvanically isolated transistors with matched hFE (min 200 @ IC = 10 µA), VCEO = 45 V, and low VCE(sat) = 90 mV @ IC = 10 mA/IB = 0.5 mA. It is designed for AF input stages and driver applications in compact audio preamps and sensor interface circuits.
For engineers reviewing the BC847SE6433BTMA1 datasheet, BC847SE6433BTMA1 pinout, BC847SE6433BTMA1 application, or BC847SE6433BTMA1 equivalent, key selection criteria include dual-transistor matching tolerance, thermal resistance RthJS ≤ 140 K/W, AEC-Q101 qualification, RoHS compliance, and SOT363 footprint compatibility with space-constrained PCB layouts.
Technical Context
This dual NPN array integrates two electrically isolated transistors on a single die with tightly controlled hFE matching and identical DC/AC characteristics. Its design supports cascaded amplification or complementary push-pull configurations without cross-coupling.
The device operates with VCEO = 45 V, fT = 250 MHz, Ccb = 0.95 pF, and noise figure F = 10 dB @ IC = 200 µA - enabling stable mid-frequency gain in low-noise analog front-ends where thermal stability and parameter consistency across channels are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - maximum collector-emitter voltage before breakdown; defines safe operating range in 24 V rail driver stages |
| hFE (min) | 200 @ IC = 10 µA - ensures reliable current amplification at low bias currents for battery-powered sensor interfaces |
| VCE(sat) | 90 mV @ IC = 10 mA/IB = 0.5 mA - minimizes conduction loss in switching applications like LED current control |
| fT | 250 MHz - supports stable gain up to ~100 MHz, suitable for audio band and low-speed digital signal conditioning |
| RthJS | ≤140 K/W - enables 250 mW power dissipation at TS ≤ 115 °C; critical for thermal management in sealed enclosures |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
SOT363 (SC74) surface-mount package: 6-pin, 2.5 mm × 1.25 mm footprint, 0.65 mm pitch, gull-wing leads, tape-and-reel packaging (3000 pcs/reel ø180 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (E1) | Emitter of Transistor 1 | Low-impedance current sink node for first NPN; tied to local ground reference in differential pair designs |
| 2 (B1) | Base of Transistor 1 | Control input for first transistor; requires current-limited drive to avoid saturation delay |
| 3 (C2) | Collector of Transistor 2 | Active output node for second transistor; routed to load or next stage with minimal parasitic inductance |
| 4 (E2) | Emitter of Transistor 2 | Independent emitter terminal enabling separate biasing or current sensing per channel |
| 5 (B2) | Base of Transistor 2 | Second independent control path; allows synchronous or phase-shifted operation vs. TR1 |
| 6 (C1) | Collector of Transistor 1 | Primary output for first transistor; optimized for low VCE(sat) in switching mode |
Key Features
| Feature | Design Value |
|---|---|
| Dual galvanically isolated NPN transistors | Enables independent biasing and signal routing without substrate coupling; essential for noise-sensitive analog pairs |
| Matched hFE and VBE across channels | Reduces gain mismatch to < ±5% in production lots, improving CMRR in differential amplifiers |
| Low VCE(sat) (90 mV typical) | Minimizes power loss and self-heating in high-duty-cycle switching applications such as PWM dimming drivers |
| AEC-Q101 qualified | Validated for automotive under-hood environments including 150 °C junction operation and 1000-cycle temperature cycling |
Applications
| Audio Pre-amplifier Stage | Sensor Signal Conditioning |
|---|---|
Use Scenario: Dual-stage low-noise amplification of electret microphone output in portable voice recorders. IC Role / Device Role / Timing Role: First transistor provides high-Z input buffering; second delivers gain with matched DC bias.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B,315 (Nexperia) | Single NPN in SOT23; no dual-channel integration or internal isolation | Requires two devices and additional layout area for same functionality | Select when board space permits discrete placement and cost sensitivity outweighs integration benefit |
| MBT3904DW1T1G (onsemi) | hFE min = 100 @ IC = 10 mA; higher VCE(sat) = 200 mV @ same bias; not AEC-Q101 qualified | Limited to commercial-grade consumer electronics; unsuitable for automotive or industrial ambient extremes | Select only for non-automotive, cost-driven applications where matching and qualification are not required |
Compared with BC847SE6433BTMA1, BC847B,315 increases component count and layout complexity, while MBT3904DW1T1G sacrifices automotive reliability and channel matching - making the BC847SE6433BTMA1 optimal for space-constrained, AEC-Q101–compliant dual-transistor functions.

FAQ
What is the maximum continuous collector current per transistor in BC847SE6433BTMA1?
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 individually to each NPN element; simultaneous full-load operation of both transistors requires derating based on total power dissipation limits and thermal layout.
Is BC847SE6433BTMA1 pin-compatible with BC846S or BC847S variants?
Yes - BC847SE6433BTMA1 shares identical SOT363 pinout (E1-B1-C2-E2-B2-C1) and mechanical footprint with BC846S and BC847S. Electrical differences exist (e.g., VCEO = 45 V vs. 65 V for BC846S), so direct substitution requires verification of voltage margin in the target circuit.
Does BC847SE6433BTMA1 support pulsed operation beyond its DC power rating?
Yes - the device supports pulsed loads up to Ptot(max)/Ptot(DC) = 10× for pulse widths ≤ 10 ms (duty cycle ≤ 2%), as shown in Figure 7 of the datasheet. Thermal design must account for transient junction temperature rise using RthJS ≤ 140 K/W and appropriate PCB copper area.
How is the "E6433" suffix in BC847SE6433BTMA1 interpreted?
The "E6433" denotes Nexperia's internal traceability code: "E" indicates wafer fab location, "6433" is a unique lot/batch identifier linked to process parameters and test data. It does not affect electrical specifications but enables full traceability for automotive PPAP and failure analysis.
