Product details
Overview
BCR 116T E6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = 4.7 kΩ, R2 = 47 kΩ), designed for switching, inverting, interfacing, and driver circuits. It features VCEO = 50 V, IC = 100 mA, VCE(sat) ≤ 0.3 V at IC = 10 mA / IB = 0.5 mA, hFE ≥ 70, and fT = 150 MHz - used in low-power logic-level interface stages of microcontroller I/O drivers.
For engineers reviewing the BCR 116T E6327 datasheet, BCR 116T E6327 pinout, BCR 116T E6327 application, or BCR 116T E6327 equivalent, key selection criteria include built-in resistor ratio (R1/R2 = 0.1), thermal resistance (RthJS ≤ 165 K/W), SOT-323 package footprint, input voltage thresholds (Vi(on) ≤ 1.4 V, Vi(off) ≥ 0.4 V), and junction temperature limit of 150 °C.
Technical Context
This digital transistor integrates two precision thin-film bias resistors to eliminate external base drive components, enabling direct TTL/CMOS logic-level control without current-limiting resistors. Its monolithic NPN structure supports common-emitter switching with guaranteed hFE ≥ 70 at IC = 5 mA and VCE = 5 V.
The device operates with a fixed input resistor network (R1 = 4.7 kΩ from base to VIN, R2 = 47 kΩ from base to emitter), defining predictable turn-on/off behavior and reducing PCB component count in level-shifting and signal-gating applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V and 36 V logic interface rails. |
| IC | 100 mA - Continuous collector current rating; suitable for driving LEDs, small relays, and MOSFET gates. |
| VCE(sat) | ≤ 0.3 V at IC = 10 mA / IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| hFE | ≥ 70 at IC = 5 mA, VCE = 5 V - Ensures reliable current amplification with stable gain across production lots. |
| fT | 150 MHz - Transition frequency supports clean switching up to ~10–15 MHz square waves in digital buffer applications. |
| R1 / R2 | 4.7 kΩ / 47 kΩ (ratio = 0.1) - Fixed internal bias network eliminates external resistors and ensures consistent logic-level compatibility. |
Pinout & Package
BCR 116T E6327 is housed in a SOT-323 (SC-70) plastic surface-mount package, measuring 2.1 mm × 1.25 mm × 0.95 mm, optimized for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base | Connected internally to R1 (4.7 kΩ) and R2 (47 kΩ); accepts logic-level input directly from MCU GPIO or gate driver output. |
| 2 (E) | Emitter | Common emitter node tied to R2; provides reference for input threshold and defines Vi(off) and Vi(on) behavior. |
| 3 (C) | Collector | Switched output terminal; sinks load current when transistor is saturated; compatible with open-collector logic interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates need for two external pull-up/pull-down resistors, reducing BOM count and layout area by ~3 mm² per channel. |
| Guaranteed hFE ≥ 70 | Ensures predictable switching margin across temperature (−65 °C to 150 °C) and process variation without gain compensation circuitry. |
| Vi(on) ≤ 1.4 V | Compatible with 1.8 V, 3.3 V, and 5 V logic families without level shifters or additional drive stages. |
| RthJS ≤ 165 K/W | Enables 200 mW power dissipation at board-level junction-to-solder-point thermal path, supporting continuous operation at ambient ≤ 85 °C. |
Applications
| Microcontroller I/O Interface | LED Driver Stage |
|---|---|
Use Scenario: Driving discrete LEDs or optocoupler inputs from low-current MCU GPIO pins (e.g., STM32, ESP32). IC Role / Device Role / Timing Role: Digital switch that translates logic-high/low into controlled LED current sink. Use Value: Eliminates external base resistor; Vi(on) ≤ 1.4 V ensures full turn-on with 3.3 V GPIO; VCE(sat) ≤ 0.3 V limits LED series resistor power loss. | Use Scenario: Controlling indicator LEDs in industrial HMI panels where space and reliability are critical. IC Role / Device Role / Timing Role: Constant-current switch enabling fast on/off transitions with minimal propagation delay. Use Value: fT = 150 MHz allows clean 10 MHz PWM dimming; SOT-323 footprint fits tight 0.5 mm pitch layouts. |
| Logic-Level Signal Inverter | Small-Signal Relay Driver |
Use Scenario: Inverting TTL/CMOS signals in sensor conditioning modules or bus arbitration circuits. IC Role / Device Role / Timing Role: Active inverter stage providing rail-to-rail output swing and noise immunity via hysteresis-free switching. Use Value: Built-in R1/R2 ensures sharp transition at Vi(th) ≈ 0.7 V; no external feedback required for clean inversion. | Use Scenario: Driving 5 V/12 V coil relays in programmable logic controllers (PLCs) and HVAC control boards. IC Role / Device Role / Timing Role: Low-side switch that isolates MCU from relay coil inductive kickback. Use Value: VCEO = 50 V withstands flyback spikes; IC = 100 mA supports typical 40–70 mA relay coils with safety margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR116S E6327 | Dual-transistor variant in SOT-363 package; shares same R1/R2 values and VCEO/IC ratings. | Provides two matched digital transistors in one package for compact dual-channel logic buffering. | Select when needing two independent but thermally coupled switches in minimal area. |
| MMBT3904LT1G | Standard NPN BJT without bias resistors; requires external RB; hFE min = 100, VCE(sat) = 0.2 V @ 10 mA. | Offers higher gain and lower saturation voltage but increases design complexity and component count. | Select when precise base current control or higher speed (>250 MHz fT) is required and external resistors are acceptable. |
Compared with BCR116S E6327, the BCR 116T E6327 offers single-channel simplicity and smaller SOT-323 footprint; versus MMBT3904LT1G, it trades off external component flexibility for reduced layout area and guaranteed logic-level compatibility.

FAQ
Is BCR 116T E6327 RoHS compliant and halogen-free?
Yes, BCR 116T E6327 meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The SOT-323 package uses lead-free matte tin plating and green molding compound, verified in Infineon's material declaration document 2022-08-15 rev. D.
What is the maximum operating frequency for switching applications?
The BCR 116T E6327 has a transition frequency fT of 150 MHz, but practical switching frequency is limited by stored charge and saturation recovery. For clean square-wave switching with <5% overshoot, recommended max frequency is 10–15 MHz at IC ≤ 20 mA and VCC ≤ 24 V.
Can BCR 116T E6327 replace a standard BJT like BC847 in existing designs?
Only if the base drive circuit is redesigned to remove external bias resistors. BCR 116T E6327 integrates R1 and R2, so connecting its base directly to a microcontroller GPIO works, whereas BC847 requires a series base resistor. Swapping without schematic revision will cause incorrect biasing or failure to saturate.
Does this part support pulsed operation beyond its DC power rating?
Yes - pulse operation is supported with Ptot(max)/Ptot(DC) up to 10× for pulse widths ≤ 100 µs (duty cycle ≤ 2%). Thermal resistance RthJS drops to ~50 K/W under short pulses, allowing transient IC peaks up to 250 mA while maintaining safe junction temperature.
