Product details
Overview
BCR 103T E6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 2.2 kΩ), designed for low-power switching, interface, and driver circuits in space-constrained applications. It features VCEO = 50 V, IC = 100 mA, VCE(sat) ≤ 0.3 V at IC = 20 mA/IB = 1 mA, fT = 140 MHz, and operates up to Tj = 150 °C in SC75 package.
For engineers reviewing the BCR 103T E6327 datasheet, BCR 103T E6327 pinout, BCR 103T E6327 application, or BCR 103T E6327 equivalent, key selection criteria include input threshold voltage (Vi(on) = 0.8–2.5 V), built-in resistor ratio (R1/R2 = 0.9–1.1), thermal resistance (RthJS ≤ 165 K/W), and SC75 footprint compatibility for high-density PCB layouts.
Technical Context
This digital transistor integrates two matched 2.2 kΩ bias resistors to enable direct logic-level drive without external components-reducing component count in level-shifting and microcontroller I/O interfacing. Its common-emitter configuration supports fast switching with fT = 140 MHz and low VCE(sat), while RthJS = 165 K/W reflects thermal limitations of the SC75 package at elevated ambient temperatures.
The device exhibits defined input thresholds: Vi(on) ≤ 2.5 V ensures reliable turn-on with 3.3 V logic, and Vi(off) ≥ 0.8 V guarantees noise immunity. Cutoff leakage (ICBO ≤ 100 nA, IEBO ≤ 3.5 mA) and hFE ≥ 20 at IC = 20 mA support stable DC gain in saturated-switch operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; defines safe operating range in 24 V and 36 V interface circuits. |
| IC | 100 mA - Continuous collector current rating; suitable for driving LEDs, small relays, and logic buffers. |
| VCE(sat) | ≤ 0.3 V at IC = 20 mA/IB = 1 mA - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| fT | 140 MHz - Transition frequency enables use in signal conditioning up to ~10 MHz square-wave switching. |
| R1 / R2 | 2.2 kΩ / 2.2 kΩ - Matched internal base bias network eliminates external resistors for simplified 3.3 V/5 V GPIO interfacing. |
| RthJS | ≤ 165 K/W - Junction-to-solder-point thermal resistance limits usable power dissipation to 250 mW at TS ≤ 109 °C. |
| Vi(on) | 0.8–2.5 V - Input voltage range ensuring reliable turn-on with standard CMOS/TTL logic outputs. |
Pinout & Package
BCR 103T E6327 is housed in the SC75 (SOT-416) surface-mount package: 1.6 mm × 0.8 mm × 0.55 mm, single-row 3-pin, tape-and-reel packing (E6327 = 3,000 pcs/reel, ø180 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base connection via internal R1–R2 divider | Input node for logic-level control; internally biased-no external pull-up/down required. |
| 2 (E) | Emitter | Common reference terminal; tied to GND in low-side switch configurations. |
| 3 (C) | Collector | Switched output node; connects to load (e.g., LED anode or relay coil) in open-collector topology. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual bias resistors | R1 = R2 = 2.2 kΩ ±30 %, enabling direct microcontroller GPIO drive without external components. |
| Low VCE(sat) | ≤ 0.3 V at rated IC/IB, reducing conduction loss and thermal stress in battery-powered systems. |
| High fT | 140 MHz typical, supporting clean edge integrity in digital signal buffering up to 10 MHz. |
| SC75 footprint | 0.8 mm body width and 0.65 mm pitch allow placement in ultra-dense portable electronics PCBs. |
| Wide Vi(off) margin | Vi(off) ≤ 1.5 V ensures robust noise rejection against EMI in industrial control I/O modules. |
Applications
| LED Driver Circuit | Microcontroller I/O Interface |
|---|---|
Use Scenario: Driving indicator LEDs from 3.3 V MCU GPIO pins in handheld medical devices. IC Role / Device Role / Timing Role: Low-side saturated switch controlling LED current path to ground. Use Value: Built-in R1/R2 eliminates two external resistors per channel, saving 0.5 mm² PCB area per LED. | Use Scenario: Level-shifting between 5 V legacy peripherals and 3.3 V ARM Cortex-M0+ controllers. IC Role / Device Role / Timing Role: Digital buffer isolating voltage domains while preserving signal timing integrity. Use Value: Vi(on) ≤ 2.5 V ensures full logic '1' recognition; fT > 100 MHz avoids pulse distortion at 1 MHz SPI clock rates. |
| Relay Driver Module | Industrial Sensor Signal Conditioning |
Use Scenario: Activating 12 V/20 mA reed relays in programmable logic controller (PLC) output cards. IC Role / Device Role / Timing Role: High-gain saturated switch amplifying weak control signals into relay coil drive current. Use Value: hFE ≥ 20 at IC = 20 mA provides sufficient current gain to drive relay coils without additional stages. | Use Scenario: Converting analog sensor output (e.g., thermistor voltage divider) into clean digital on/off signals for HVAC control units. IC Role / Device Role / Timing Role: Schmitt-trigger-like comparator substitute using Vi(on)/Vi(off) hysteresis. Use Value: 0.7 V input hysteresis (Vi(on) − Vi(off)) suppresses contact bounce and line noise in 24 V industrial environments. |
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, hFE = 30–200, R1 = 4.7 kΩ, R2 = 4.7 kΩ | Higher voltage rating and wider hFE spread; suited for 48 V bus monitoring where 50 V margin is insufficient. | Select when higher VCEO or lower input current (IB ≈ 0.5 mA) is required. |
| NSVD103T1T1G | Same SC75 package; R1 = R2 = 2.2 kΩ, but VCEO = 50 V, VCE(sat) = 0.25 V max, fT = 200 MHz | Lower saturation voltage and higher fT; better for high-speed switching (>5 MHz) or ultra-low-loss LED drivers. | Prefer when minimizing conduction loss or extending bandwidth beyond 100 MHz is critical. |
Compared with BCR 103T E6327, BCR 108T offers higher voltage headroom but reduced input sensitivity, while NSVD103T1T1G delivers superior speed and efficiency at marginally higher cost-making each optimal for distinct trade-offs in voltage, speed, and thermal design.

FAQ
Is BCR 103T E6327 pin-compatible with BCR 103F or BCR 103L3?
Yes-BCR 103T, BCR 103F, and BCR 103L3 share identical pinout (B-E-C) and SC75/SOT-416 footprint, but differ in thermal ratings: BCR 103T has RthJS ≤ 165 K/W and max TS = 109 °C, whereas BCR 103F supports TS ≤ 128 °C. Electrical specs are otherwise identical.
What is the maximum allowable continuous power dissipation at 85 °C ambient?
At TA = 85 °C, derated Ptot for BCR 103T E6327 is approximately 160 mW, calculated using RthJA ≈ 320 K/W (typical for SC75 on 2-layer board) and Tj(max) = 150 °C: P = (150 − 85) / 320 ≈ 0.203 W. Actual value depends on PCB copper area and airflow.
Can BCR 103T E6327 be used in linear amplifier configurations?
No-it is optimized for saturated switching, not linear operation. The integrated bias resistors fix the base current path, preventing adjustable Q-point setting. Its hFE variation (20 min, no typ/max) and lack of small-signal linearity data confirm it is not intended for analog amplification.
Does the E6327 packing code indicate RoHS compliance?
Yes-E6327 denotes lead-free, halogen-free packaging compliant with EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), with peak reflow temperature up to 260 °C.
