Product details
Overview
BCR 101T 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 in low-power logic-level applications. It features VCEO = 50 V, IC = 50 mA, VCE(sat) ≤ 0.3 V at IC = 5 mA/IB = 0.25 mA, and fT = 100 MHz, commonly used in microcontroller GPIO interface and LED driver stages.
For engineers reviewing the BCR 101T E6327 datasheet, BCR 101T E6327 pinout, BCR 101T E6327 application, or BCR 101T E6327 equivalent, key selection criteria include input threshold voltage (Vi(on) = 1–3 V), built-in resistor ratio (R1/R2 = 0.9–1.1), thermal resistance (RthJS ≤ 165 K/W), SC75 package footprint, and guaranteed hFE ≥ 70 at 5 mA/5 V.
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 single-pin control with fixed base biasing, eliminating need for discrete resistor networks in level-shifting or load-switching nodes.
The SC75 package delivers compact board area (1.6 × 1.6 mm) and thermal performance optimized for ambient-temperature-limited PCB layouts. Electrical behavior is characterized at TA = 25°C with pulse testing (t < 300 µs, D < 2%) to ensure stable gain and saturation under transient drive conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; sets safe operating range for 3.3 V/5 V logic-driven loads. |
| IC | 50 mA - Continuous collector current rating; supports driving LEDs, small relays, or MOSFET gates directly from MCU pins. |
| VCE(sat) | ≤ 0.3 V at IC = 5 mA/IB = 0.25 mA - Low saturation voltage minimizes power loss and heat generation in on-state switching. |
| fT | 100 MHz - Transition frequency confirms suitability for high-speed digital switching up to ~10 MHz square-wave operation. |
| R1 / R2 | 70–130 kΩ / ratio 0.9–1.1 - Tight tolerance ensures predictable turn-on/off thresholds across temperature and process variation. |
| hFE | ≥ 70 at IC = 5 mA/VCE = 5 V - Sufficient DC current gain to guarantee reliable saturation with standard logic output currents. |
| Ptot | 250 mW at TS ≤ 109°C - Total power dissipation limit defines maximum continuous power handling in SC75 thermal environment. |
Pinout & Package
BCR 101T E6327 uses the SC75 (SOT-416) surface-mount package: 1.6 mm × 1.6 mm body, 0.45 mm max height, three terminals in single-row configuration. Pin 1 = Base (B), Pin 2 = Emitter (E), Pin 3 = Collector (C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base connection with internal R1–R2 divider | Accepts logic-level input; internal 100 kΩ pull-up/pull-down enables direct TTL/CMOS drive without external resistors. |
| 2 (E) | Emitting terminal | Common reference node for input and output paths; tied to system ground in standard switch configurations. |
| 3 (C) | Collector output | Drives load between VCC and collector; supports active-low switching with saturated conduction below 0.3 V drop. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Dual 100 kΩ resistors (R1 = base-to-VCC, R2 = base-to-emitter) eliminate external components for logic-compatible switching. |
| Guaranteed Vi(on)/Vi(off) | Vi(on) = 1–3 V and Vi(off) = 0.5–1.8 V ensure robust recognition of 3.3 V and 5 V logic HIGH/LOW states. |
| Thermal derating curve | Ptot = 250 mW only when solder-point temperature ≤ 109°C; enables accurate thermal design in confined layouts. |
| High-frequency capability | fT = 100 MHz supports clean edge response in PWM dimming, clock buffering, and data line inversion up to 10 MHz. |
| Low leakage | ICBO ≤ 100 nA and IEBO ≤ 75 µA minimize standby current in battery-powered or always-on interface circuits. |
Applications
| Microcontroller GPIO Interface | LED Driver Stage |
|---|---|
Use Scenario: Driving discrete LEDs from 3.3 V or 5 V MCU I/O pins with current limiting via collector resistor. IC Role / Device Role / Timing Role: Digital switch translating logic-level output into controlled current sink for indicator or status lighting. Use Value: Eliminates need for two external bias resistors; Vi(on) ≤ 3 V ensures full saturation with standard GPIO HIGH, while VCE(sat) ≤ 0.3 V keeps LED forward voltage drop predictable. |
Use Scenario: Controlling multi-color RGB LED anodes in portable instrumentation displays. IC Role / Device Role / Timing Role: Low-side switch enabling PWM brightness control with minimal propagation delay and consistent duty-cycle fidelity. Use Value: fT = 100 MHz supports >5 MHz PWM carrier frequencies; tight R1/R2 ratio maintains uniform turn-on timing across color channels. |
| Logic-Level Signal Inverter | Small-Relay Driver |
Use Scenario: Converting active-high control signals to active-low outputs for legacy peripherals or optocoupler inputs. IC Role / Device Role / Timing Role: Single-transistor inverter stage with defined input hysteresis via internal resistor network. Use Value: Vi(off) ≤ 1.8 V guarantees clean LOW recognition; hFE ≥ 70 ensures full saturation even with weak drive sources like open-drain buffers. |
Use Scenario: Activating 5 V/12 V coil relays in industrial sensor interface modules. IC Role / Device Role / Timing Role: Interface transistor providing isolation and current gain between low-power controller and inductive load. Use Value: VCEO = 50 V withstands relay coil flyback spikes; Ptot = 250 mW allows continuous operation with proper PCB copper pour and thermal relief. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR108T E6327 | VCEO = 60 V, R1 = 47 kΩ, R2 = 47 kΩ, hFE ≥ 100 | Higher voltage rating and lower bias resistance support 12 V logic interfaces and faster switching | Select when driving higher-voltage loads or requiring reduced input current (IB ≈ 2× higher than BCR101T at same VIN) |
| NSVD101PT1G | Package: SOT-416 (SC75), R1 = 100 kΩ, R2 = 100 kΩ, VCEO = 50 V, but IC = 100 mA | Double collector current rating enables higher-power LED or relay loads without redesign | Choose when existing layout must accommodate increased load current while retaining identical footprint and bias behavior |
Compared with BCR101T E6327, BCR108T offers higher voltage margin and gain at the cost of increased input current, while NSVD101PT1G doubles current capacity within the same SC75 outline-making both viable for upgraded reliability or extended voltage/current scope without board rework.

FAQ
Is BCR 101T E6327 RoHS compliant and halogen-free?
Yes. BCR 101T E6327 conforms to RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The SC75 package uses lead-free matte tin plating, and material declarations confirm absence of brominated flame retardants and chlorine-based compounds.
What is the maximum allowable peak pulse current for BCR 101T E6327?
The datasheet specifies permissible pulsed load using Ptot(max)/Ptot(DC) curves: at tp = 100 µs and duty cycle D = 0.02, peak current can reach ~200 mA. This is derived from thermal limits and pulse derating graphs on page 6 of the official Infineon BCR101 document.
Can BCR 101T E6327 replace a standard 2N3904 with external bias resistors?
Yes, but only in saturated-switch applications where Vi(on) ≥ 1 V and load current ≤ 50 mA. Unlike 2N3904, BCR 101T has fixed internal biasing-no adjustment possible-and its VCE(sat) is optimized for logic-level drive, not linear amplification.
Does the SC75 package support automated optical inspection (AOI) after reflow?
Yes. The SC75 outline (1.6 × 1.6 mm, 0.45 mm height) and clearly defined marking layout (including "101T" top-side laser marking) meet IPC-A-610 Class 2 AOI detectability requirements for solder joint presence, alignment, and polarity verification.
