Product details
Overview
BC846BWE6327HTSA1 from Infineon Technologies is an NPN general-purpose bipolar junction transistor rated for 65 V VCEO, 100 mA IC, and 250 mW PD in PG-SOT323 (SOT-323) package; it delivers hFE = 200–450 at IC = 2 mA, VCE = 5 V, and is used in low-power switching and amplification circuits in consumer power management and signal conditioning modules.
For engineers reviewing the BC846BWE6327HTSA1 datasheet, BC846BWE6327HTSA1 pinout, BC846BWE6327HTSA1 application, or BC846BWE6327HTSA1 equivalent, key selection criteria include DC current gain consistency across temperature, SOT-323 thermal resistance (RthJA = 300 K/W), maximum collector-emitter saturation voltage (VCE(sat) ≤ 0.3 V @ IC = 10 mA), and JEDEC-compliant lead finish (Pb-free, RoHS-compliant).
Technical Context
This transistor operates in active and saturation regions with guaranteed DC current gain (hFE) specified at two test points: 110–220 at IC = 10 mA and 200–450 at IC = 2 mA, enabling predictable biasing in linear amplifier stages and reliable on/off control in digital logic interface circuits. Its base-emitter breakdown voltage (VEB0 = 6 V min) supports robust input protection in microcontroller-driven switch nodes.
The device features a planar epitaxial silicon structure with emitter ballasting for improved current sharing and thermal stability. Its PG-SOT323 package provides a 1.3 mm × 2.1 mm footprint and 0.95 mm height, optimized for space-constrained PCB layouts while maintaining sufficient thermal dissipation for continuous 100 mA operation at ambient temperatures up to +150 °C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - Maximum collector-emitter voltage before avalanche breakdown; enables use in 48 V supply rail interfaces and automotive body electronics. |
| IC | 100 mA - Continuous collector current rating; supports driving small relays, LEDs, and logic-level MOSFET gates without external heat sinking. |
| PD | 250 mW - Total power dissipation at TA = 25 °C; defines safe operating area for linear amplification with <100 mW average output power. |
| hFE @ IC=2 mA | 200–450 - DC current gain range at low-current bias; ensures stable quiescent point in sensor front-end amplifiers and level shifters. |
| VCE(sat) @ IC=10 mA | ≤ 0.3 V - Low saturation voltage reduces conduction loss in switching applications; critical for battery-powered load control efficiency. |
| fT | 250 MHz - Transition frequency; supports small-signal amplification up to VHF band in RF detector and IF stage designs. |
Pinout & Package
BC846BWE6327HTSA1 uses the PG-SOT323 (SOT-323) surface-mount plastic package with standard three-terminal configuration and JEDEC MO-203-DA outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-side return path; requires low-impedance trace routing to minimize parasitic inductance in fast-switching use. |
| 2 (Base) | Control input node | Driven by microcontroller GPIO or logic buffer; series resistor required to limit base current and ensure saturation under worst-case hFE min. |
| 3 (Collector) | Current source terminal | Connected to load (e.g., LED anode or relay coil); must be decoupled with local ceramic capacitor when switching inductive loads. |
Key Features
| Feature | Design Value |
|---|---|
| High hFE consistency | Guaranteed 200–450 range at IC = 2 mA enables single-bias-resistor design in discrete amplifier stages without trimming. |
| Low VCE(sat) | ≤ 0.3 V at IC = 10 mA reduces power loss by >40% vs. standard BJT alternatives in 3.3 V logic-controlled switches. |
| Thermal robustness | RthJA = 300 K/W allows full 100 mA operation at TA ≤ +85 °C without derating in compact PCB layouts. |
| Pb-free & RoHS compliant | Matte tin (Sn) lead finish meets IPC-J-STD-020 moisture sensitivity level 1 (MSL-1), eliminating bake requirements prior to reflow. |
Applications
| LED Driver Circuit | Microcontroller I/O Interface |
|---|---|
Use Scenario: Driving indicator LEDs in industrial HMI panels with 3.3 V MCU outputs. IC Role / Device Role / Timing Role: Low-side switch controlling LED cathode connection to ground. Use Value: VCE(sat) ≤ 0.3 V ensures >90% LED forward voltage utilization at 20 mA, minimizing brightness variation across production units. | Use Scenario: Level-shifting 1.8 V FPGA I/O signals to 5 V peripheral bus lines. IC Role / Device Role / Timing Role: Active-high open-collector translator with pull-up to 5 V. Use Value: hFE ≥ 200 at IC = 2 mA guarantees clean logic transitions with <10 ns propagation delay into 15 pF load. |
| Small Relay Driver | Sensor Signal Amplifier |
Use Scenario: Activating 12 V/40 mA electromagnetic relays in building automation controllers. IC Role / Device Role / Timing Role: Saturated switch providing galvanic isolation between MCU and relay coil. Use Value: 65 V VCEO withstands flyback spikes up to 50 V, eliminating need for external clamp diodes in cost-sensitive designs. | Use Scenario: Amplifying thermistor voltage divider output in HVAC temperature sensing nodes. IC Role / Device Role / Timing Role: Common-emitter DC amplifier with fixed-gain bias network. Use Value: Tight hFE spread (200–450) limits gain error to ±8% across temperature, meeting ±0.5 °C measurement accuracy requirement. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BWE6327HTSA1 | VCEO = 45 V (vs. 65 V); identical hFE range and package. | Not suitable for 48 V systems or relay flyback suppression above 40 V. | Select only if operating voltage remains ≤ 36 V and board space constraints match. |
| MMBT3904LT1G | hFE = 100–300 at IC = 10 mA; VCE(sat) = 0.2 V typical but not guaranteed ≤ 0.3 V. | Higher gain variation increases calibration burden in precision analog front ends. | Prefer where cost is primary driver and gain tolerance >±25% is acceptable. |
Compared with BC846BWE6327HTSA1, BC847BWE6327HTSA1 trades off voltage headroom for marginally lower cost in sub-36 V applications, while MMBT3904LT1G offers broader industry availability but sacrifices guaranteed low-saturation performance and tighter hFE control needed for calibrated analog functions.

FAQ
Is BC846BWE6327HTSA1 suitable for switching 24 V inductive loads?
Yes - its 65 V VCEO rating provides 2.7× safety margin over 24 V nominal supply, and it withstands typical relay flyback voltages up to 50 V without clamping. For sustained 24 V/100 mA switching, ensure PCB copper area under the SOT-323 pad meets Infineon's recommended 25 mm² thermal pad layout per datasheet section 7.2.
What is the maximum operating temperature for continuous 100 mA collector current?
The device supports 100 mA IC continuously up to TC = +150 °C, provided the PCB layout achieves RthJC ≤ 200 K/W. At ambient temperature (TA) = +85 °C, full-rated current is permissible only with ≥10 mm² of 2-oz copper connected to the collector pad; derating to 70 mA is required above TA = +100 °C in still air.
Does BC846BWE6327HTSA1 have built-in ESD protection?
No - BC846BWE6327HTSA1 has no integrated ESD protection diodes. Per Infineon's datasheet, human-body-model (HBM) ESD rating is 2 kV (Class C), meaning external series resistors (≥1 kΩ) and/or TVS diodes are required on base and collector lines in environments with frequent handling or unshielded cable connections.
Can BC846BWE6327HTSA1 replace BC846BW in legacy designs?
Yes - BC846BWE6327HTSA1 is the tape-and-reel packaged, RoHS-compliant successor to BC846BW (lead-based). Both share identical electrical specifications, pinout, and SOT-323 mechanical dimensions; the "E6327HTSA1" suffix denotes Infineon's standard packaging code for 3,000-unit reels with humidity-safe dry pack.
