Product details
Overview
BCR 116L3 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, and hFE ≥ 70 at IC = 5 mA, used in low-power logic-level interface applications such as microcontroller GPIO drivers.
For engineers reviewing the BCR 116L3 E6327 datasheet, BCR 116L3 E6327 pinout, BCR 116L3 E6327 application, or BCR 116L3 E6327 equivalent, key selection criteria include input threshold voltage (Vi(on) = 0.5–1.4 V), built-in resistor ratio (R1/R2 = 0.09–0.11), thermal resistance (RthJS ≤ 60 K/W), SOT23-3 package compatibility, and DC current gain stability across 0.1–100 mA collector current range.
Technical Context
This digital transistor integrates two precision bias resistors to enable single-pin base drive without external components, simplifying level-shifting and open-collector interface designs. Its internal R1–R2 network provides fixed current-limiting and turn-on control, eliminating need for discrete base resistors in microcontroller output stages.
The device operates in common-emitter configuration with guaranteed VCE(sat) ≤ 0.3 V under specified drive conditions and maintains hFE ≥ 70 up to 5 mA IC, supporting reliable on/off switching in 3.3 V and 5 V digital systems with minimal layout overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum allowable voltage between collector and emitter before breakdown; supports 3.3 V/5 V rail-to-rail switching with margin. |
| IC | 100 mA - Continuous collector current rating; suitable for driving LEDs, small relays, or logic inputs. |
| VCE(sat) | ≤ 0.3 V at IC = 10 mA / IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in active switching. |
| hFE | ≥ 70 at IC = 5 mA, VCE = 5 V - Ensures sufficient current gain for predictable switching behavior with standard MCU GPIO drive strength. |
| R1 / R2 | 4.7 kΩ / 47 kΩ - Fixed internal bias network enables direct connection to CMOS/TTL outputs without external resistors. |
| fT | 150 MHz typ. - Supports high-speed switching up to ~10–20 MHz square waves with controlled edge integrity. |
| RthJS | ≤ 60 K/W - Junction-to-solder-point thermal resistance allows 250 mW dissipation at TS ≤ 135°C in SOT23-3 footprint. |
Pinout & Package
BCR 116L3 E6327 uses the SOT23-3 (TSFP-3) surface-mount package with standard lead frame geometry and moisture sensitivity level MSL3. Pin 1 is Base (B), Pin 2 is Emitter (E), Pin 3 is Collector (C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base terminal with internal R1–R2 divider | Accepts logic-level input; R1 connects to input, R2 pulls base to emitter for defined off-state. |
| 2 (E) | Emitter terminal | Common reference node for both bias resistors and transistor junction; tied to system ground in most configurations. |
| 3 (C) | Collector terminal | Switched output node; connects to load (e.g., LED anode, relay coil, pull-up net) with current path through emitter. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates two external resistors, reducing PCB area and BOM count in GPIO interface designs. |
| Vi(on) range | 0.5–1.4 V ensures reliable turn-on from 1.8 V, 3.3 V, and 5 V logic families without level translation. |
| Vi(off) max | 0.8 V guarantees robust noise immunity and prevents false triggering from leakage or crosstalk. |
| Thermal performance | RthJS ≤ 60 K/W enables sustained 100 mA operation at board temperatures up to 135°C ambient. |
| Transition frequency | fT = 150 MHz supports clean switching in clock distribution, pulse generation, and data line buffering. |
Applications
| Microcontroller GPIO Driver | LED Indicator Interface |
|---|---|
Use Scenario: Driving discrete LEDs from 3.3 V STM32 or ESP32 GPIO pins with current limiting handled internally. IC Role / Device Role / Timing Role: Digital switch translating logic-high signal into controlled current sink for LED cathode connection. Use Value: Eliminates need for external base resistor and current-limiting resistor, reducing component count by two per channel. | Use Scenario: Status indication in industrial HMI panels where space-constrained PCBs require minimal passive components. IC Role / Device Role / Timing Role: Level-shifting and current amplification stage between low-drive MCU outputs and 20 mA LED loads. Use Value: Maintains consistent brightness across supply voltages from 3.0 V to 5.5 V due to stable VCE(sat) and hFE. |
| Logic-Level Translator | Small-Signal Relay Driver |
Use Scenario: Interfacing 1.8 V FPGA I/O banks to 5 V peripheral control lines in mixed-voltage systems. IC Role / Device Role / Timing Role: Active pull-down switch enabling bidirectional voltage translation when paired with external pull-up. Use Value: Vi(on) ≤ 1.4 V ensures full turn-on with 1.8 V logic high; Vi(off) ≥ 0.4 V prevents false activation from sub-threshold noise. | Use Scenario: Activating 5 V, 100 Ω coil relays in programmable logic controllers using 3.3 V ARM Cortex-M outputs. IC Role / Device Role / Timing Role: Current-gain stage providing ≥10 mA base drive to relay transistor while isolating MCU pin. Use Value: Built-in R1/R2 delivers precise 0.5 mA base current at 3.3 V input, ensuring reliable relay closure without calculation or trimming. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B,215 | Discrete NPN BJT without bias resistors; requires external RB and RBE; hFE = 200–450; VCE(sat) = 0.2 V typ. | Used where adjustable base drive or higher gain is needed; not drop-in compatible due to missing internal resistors. | Select when fine-tuned switching thresholds or lower VCE(sat) are critical and board space permits two extra resistors. |
| NSVD112DXV6T1G | PNP digital transistor with R1 = 10 kΩ, R2 = 10 kΩ; VCEO = −50 V; complementary polarity and different resistor ratio. | Suitable for high-side switching or inverted logic interfaces; incompatible for direct replacement in NPN-based circuits. | Choose only for PNP-configured loads or when sourcing current from a positive rail is required. |
Compared with BC847B,215 and NSVD112DXV6T1G, BCR 116L3 E6327 uniquely combines fixed NPN topology, optimized R1/R2 ratio for 3.3 V logic, and SOT23-3 footprint-making it ideal for cost-sensitive, space-constrained digital interface applications where design simplicity and repeatability outweigh gain flexibility.

FAQ
What is the maximum operating temperature for BCR 116L3 E6327?
The junction temperature limit is 150°C, and the package supports total power dissipation of 250 mW at a solder-point temperature (TS) ≤ 135°C. Derating is required above that point per the Ptot vs. TS curve in the datasheet, with RthJS ≤ 60 K/W confirming thermal capability in standard SOT23-3 mounting.
Can BCR 116L3 E6327 replace a standard 2N3904 with external resistors?
Yes-it replaces a 2N3904 plus two bias resistors in common-emitter switch configurations. However, its fixed R1/R2 ratio (≈0.1) sets specific base current and turn-off behavior; verify Vi(on)/Vi(off) thresholds match your controller's logic levels before substitution.
Is BCR 116L3 E6327 suitable for PWM-driven LED dimming?
Yes-its fT = 150 MHz and fast switching characteristics support PWM frequencies up to several MHz. Ensure average power remains within 250 mW derated for board temperature, and confirm VCE(sat) stability across duty cycle variations using the published VCE(sat) vs. IC curve.
Does BCR 116L3 E6327 have AEC-Q101 qualification?
No-BCR 116L3 E6327 is not AEC-Q101 qualified. It is intended for industrial and consumer applications. For automotive use, Infineon offers AEC-Q101 qualified variants such as the BCR116MH6327, which shares identical electrical specs but undergoes extended reliability testing.
