Product details
Overview
BC846SE6433BTMA1 from Nexperia is a dual NPN silicon small-signal transistor array in SOT363 (SC74) package, featuring two galvanically isolated transistors with matched hFE and low VCE(sat) (90 mV @ 10 mA/0.5 mA). It supports AF input stages and driver applications with VCEO = 65 V, IC = 100 mA, and fT = 250 MHz - used in automotive sensor signal conditioning and compact DC-DC feedback loops.
For engineers reviewing the BC846SE6433BTMA1 datasheet, BC846SE6433BTMA1 pinout, BC846SE6433BTMA1 application, or BC846SE6433BTMA1 equivalent, key selection criteria include dual-transistor matching tolerance, thermal resistance (RthJS ≤ 140 K/W), AEC-Q101 qualification, and SOT363 footprint compatibility for space-constrained PCB layouts.
Technical Context
This device integrates two discrete NPN transistors on a single die with internal isolation, enabling matched gain (hFE = 200–450 at IC = 2 mA) and consistent VBE(sat) (580–770 mV). Its design targets analog front-end amplification where channel-to-channel tracking and low saturation voltage are critical.
The BC846S variant operates up to 65 V VCEO and delivers 250 MHz transition frequency at IC = 20 mA/VCE = 5 V, with Ccb = 0.95 pF and Ceb = 9 pF - optimized for high-frequency small-signal switching and linear amplification below 100 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - supports rail-to-rail operation in 48 V automotive subsystems without breakdown risk |
| IC | 100 mA - sufficient drive capability for LED biasing, relay drivers, and logic-level translation |
| hFE | 200–450 @ IC = 2 mA - enables stable current mirror and differential pair configurations |
| VCE(sat) | 90 mV max @ IC = 10 mA/IB = 0.5 mA - minimizes conduction loss in low-voltage switching paths |
| fT | 250 MHz - suitable for audio preamplifier stages and RF detector bias networks |
| RthJS | ≤140 K/W - allows sustained 250 mW dissipation at TS ≤ 115 °C on standard FR4 |
| AEC-Q101 | Qualified - meets stress test requirements for automotive under-hood electronics |
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.

| 3 (C2) | Collector of TR2 | High-side output node; connects to load supply rail or pull-up resistor |
| 4 (E2) | Emitter of TR2 | Independent emitter terminal enabling separate biasing or current sensing |
| 5 (B2) | Base of TR2 | Second independent control path; supports dual-gain-stage cascading |
| 6 (C1) | Collector of TR1 | Primary output collector; routed to next stage or feedback network |
Key Features
| Feature | Design Value |
|---|---|
| Dual galvanically isolated NPN transistors | Enables matched-pair operation without cross-talk; eliminates need for two discrete SOT23 devices |
| Matched hFE and VBE | Reduces gain error in differential amplifiers and current mirrors to < ±5% across temperature |

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 |
|---|---|---|---|
| BC847SE6433BTMA1 | VCEO = 45 V (vs. 65 V); otherwise identical pinout, hFE, and package | Not suitable for 48 V automotive rails; acceptable in 24 V industrial systems | Select when lower voltage rating suffices and cost optimization is prioritized |
| MBT3904DW1T1G | Higher VCEO = 40 V, but only 100–300 hFE range; no AEC-Q101 qualification | Lacks automotive qualification; wider hFE spread increases matching uncertainty | Use only in non-automotive consumer designs where qualification is not required |
Compared with BC846SE6433BTMA1, BC847SE6433BTMA1 trades 20 V headroom for identical matching and thermal specs, while MBT3904DW1T1G offers broader availability but lacks AEC-Q101 validation and guaranteed transistor pairing.

FAQ
Is BC846SE6433BTMA1 pin-compatible with BC847SE6433BTMA1?
Yes - both share identical SOT363 pinout (E1-B1-C2-E2-B2-C1), same marking layout, and mechanical footprint. The only functional difference is VCEO (65 V vs. 45 V), so substitution requires verification of maximum collector-emitter voltage in the target circuit.
What does "galvanic isolation" mean for the two transistors in this package?
Galvanic isolation means the two NPN transistors share no internal electrical connection - their collectors, emitters, and bases are fully separated. This enables independent biasing, prevents crosstalk, and supports dual-channel functions like differential pairs or isolated switch drivers without external decoupling.
Can BC846SE6433BTMA1 be used in linear amplifier configurations?
Yes - its hFE stability (200–450), low noise figure (10 dB), and matched characteristics make it suitable for Class-A preamplifiers and active filters. Operation requires VCE ≥ 1 V and IC ≤ 100 mA to stay within SOA limits defined in the Safe Operating Area curves.
Does the "E6433" suffix indicate tape-and-reel packaging?
Yes - "E6433" denotes 3,000-piece 180 mm reel packaging per JEDEC standard. The full part number BC846SE6433BTMA1 confirms SOT363 package (T), RoHS compliance (M), and tape-and-reel delivery (A1), with "BT" indicating Nexperia's internal manufacturing code.
