Product details
Overview
BCR 101L3 E6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 100 kΩ), designed for switching, inverting, interfacing, and driver circuits. It features VCEO = 50 V, IC = 50 mA, Ptot = 250 mW at TS ≤ 135°C, and hFE ≥ 70 at IC = 5 mA, VCE = 5 V - used in low-power logic-level interface modules and microcontroller GPIO drivers.
For engineers reviewing the BCR 101L3 E6327 datasheet, BCR 101L3 E6327 pinout, BCR 101L3 E6327 application, or BCR 101L3 E6327 equivalent, key selection criteria include input threshold voltage (Vi(on) = 1–3 V), saturation voltage (VCE(sat) ≤ 0.3 V), resistor ratio tolerance (R1/R2 = 0.9–1.1), thermal resistance (RthJS ≤ 60 K/W), and SC75 package compatibility with high-density PCB layouts.
Technical Context
This digital transistor integrates two precision 100 kΩ bias resistors to enable direct connection to CMOS/TTL logic outputs without external components. Its common-emitter configuration supports DC switching with guaranteed hFE ≥ 70 and VCE(sat) ≤ 0.3 V at IC = 5 mA / IB = 0.25 mA.
The device operates across –65°C to +150°C storage range and achieves fT = 100 MHz at IC = 10 mA, VCE = 5 V, making it suitable for medium-speed digital signal routing where low-input-current drive and predictable turn-on/off thresholds are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum allowable collector-emitter voltage before breakdown in switching applications |
| IC | 50 mA - continuous collector current rating defining load-driving capability |
| Ptot | 250 mW - total power dissipation limit at case temperature ≤135°C, constraining thermal design margin |
| hFE | ≥70 - minimum DC current gain at 5 mA/5 V, ensuring reliable base drive scaling |
| VCE(sat) | ≤0.3 V - low saturation voltage enabling <150 mW loss at full rated current |
| R1 / R2 | 100 kΩ ±30% - matched internal bias network eliminating external resistor layout and tolerance stack-up |
| fT | 100 MHz - transition frequency confirming suitability for signals up to ~10–20 MHz square-wave switching |
Pinout & Package
BCR 101L3 E6327 uses the SC75 (SOT-416) surface-mount package: 1.6 mm × 0.8 mm footprint, 0.45 mm height, single-row 3-pin configuration with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base connection via R1–R2 divider network | Input node for logic-level control; internally biased to VCC through R1 and to emitter through R2 |
| 2 (E) | Emitter terminal | Common reference node for both bias resistors and output current return path |
| 3 (C) | Collector terminal | Switched load connection point; carries full IC with minimal VCE(sat) drop |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual-bias resistor network | R1 = R2 = 100 kΩ ±30%, eliminating 2 external SMT resistors and reducing BOM count |
| Guaranteed Vi(on) and Vi(off) | Vi(on) = 1–3 V, Vi(off) = 0.5–1.8 V - enables robust TTL/CMOS logic-level compatibility |
| Low thermal resistance | RthJS ≤ 60 K/W - improves power handling in compact layouts without forced cooling |
| High-speed switching capability | fT = 100 MHz - supports clean edge transitions in clock distribution and pulse-width modulation circuits |
Applications
| LED Driver Interface | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V MCU outputs with limited drive strength. IC Role / Device Role / Timing Role: Digital switch translating logic-high to LED-on state with fixed current limiting via external series resistor. Use Value: Eliminates need for discrete base resistor; Vi(on) ≤ 3 V ensures full turn-on with 3.3 V logic, while VCE(sat) ≤ 0.3 V minimizes voltage drop across LED series resistor. | Use Scenario: Adding buffered digital outputs to resource-constrained embedded controllers. IC Role / Device Role / Timing Role: Level-shifting and current-boosting stage between low-drive GPIO and higher-current peripheral loads. Use Value: R1/R2 matching ensures consistent switching thresholds across multiple channels; hFE ≥ 70 guarantees >15 mA output drive with 200 µA base current. |
| Logic-Level Signal Inverter | Low-Power Sensor Interface |
Use Scenario: Inverting active-high sensor alerts into active-low interrupt inputs on ASICs. IC Role / Device Role / Timing Role: Single-transistor inverter with defined input hysteresis via R1–R2 feedback topology. Use Value: Vi(off) ≥ 0.5 V prevents false triggering from noise; fast fT-limited rise/fall times (<50 ns) preserve signal integrity at 1–5 MHz. | Use Scenario: Isolating analog sensor outputs from noisy digital domains using open-collector configuration. IC Role / Device Role / Timing Role: Active-low switch enabling pull-down of sensor output lines during standby or fault conditions. Use Value: Low ICBO ≤ 100 nA and IEBO ≤ 75 µA prevent leakage-induced offset errors; Tj = 150°C rating supports operation near heat-generating components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR108L3 E6327 | VCEO = 60 V, hFE = 160–400, R1 = 47 kΩ, R2 = 47 kΩ | Higher voltage rating and gain; lower input resistance reduces logic drive current requirement | Select when operating above 50 V or requiring tighter Vi(on) control with lower base current |
| MMBT2222ALT1G | No built-in resistors; discrete NPN with hFE = 100–300, VCEO = 40 V, requires external bias network | Greater flexibility in biasing but increases component count and layout area | Choose when custom threshold tuning or higher fT (300 MHz) is needed and board space allows extra passives |
Compared with BCR 101L3 E6327, BCR108L3 offers higher voltage margin and gain at lower input impedance, while MMBT2222ALT1G provides higher speed and design flexibility at the cost of added external components and reduced integration.

FAQ
What is the maximum junction temperature and how does it affect reliability?
The absolute maximum junction temperature (Tj) is 150°C. Operation near this limit accelerates parametric drift and reduces long-term reliability; derating is recommended above 125°C. Thermal resistance RthJS ≤ 60 K/W allows estimation of junction temperature rise above solder-point temperature under known power dissipation.
Can BCR 101L3 E6327 replace a standard NPN transistor like BC847 in all circuits?
No - BCR 101L3 E6327 integrates base bias resistors and is optimized for direct logic-level drive. Replacing a BC847 requires verifying that the circuit does not rely on adjustable base current or external bias networks; unintended forward-biasing of R2 may occur in linear amplifier configurations.
Is the SC75 package compatible with standard SOT-23 reflow profiles?
Yes - the SC75 (SOT-416) package shares thermal mass and lead geometry closely with SOT-23, and is qualified for standard Pb-free reflow profiles (peak 260°C, 30 sec max). Footprint dimensions (1.6 × 0.8 mm) differ slightly, so stencil aperture and placement accuracy must be verified per IPC-7351B.
What is the significance of the E6327 packing code?
E6327 indicates tape-and-reel packaging on 180 mm diameter reels containing 3,000 units, conforming to EIA-481-D standards. This format supports high-speed automated pick-and-place assembly and ensures moisture sensitivity level (MSL) 1 handling without baking prior to reflow.
