Product details
Overview
BCR 119L3 E6327 from Infineon Technologies is an NPN silicon digital transistor with integrated 4.7 kΩ base resistor, designed for switching, inverter, interface, and driver circuits. It features VCEO = 50 V, IE = 100 mA, VCE(sat) ≤ 0.3 V at IC = 10 mA/IB = 0.5 mA, hFE = 120–630, and operates up to Tj = 150 °C in SOT23 package.
For engineers reviewing the BCR 119L3 E6327 datasheet, BCR 119L3 E6327 pinout, BCR 119L3 E6327 application, or BCR 119L3 E6327 equivalent, key selection criteria include built-in R1 value, saturation voltage under defined drive conditions, thermal resistance (RthJS ≤ 60 K/W), DC current gain range, and SOT23 footprint compatibility for space-constrained logic-level switching.
Technical Context
This device integrates a single NPN transistor with a monolithically embedded 4.7 kΩ base bias resistor (R1), eliminating external component count in low-power digital switching applications. Its common-emitter configuration supports direct TTL/CMOS logic interfacing without discrete base resistors.
The BCR 119L3 variant uses the SOT23 package with 1=B, 2=E, 3=C pinout and achieves Ptot = 250 mW at TS ≤ 135 °C, supported by RthJS ≤ 60 K/W - enabling higher continuous current capability than standard BCR119 variants in thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum collector-emitter voltage before breakdown; enables use in 24 V industrial control and 3.3/5 V logic-driven 48 V auxiliary rails. |
| IE | 100 mA - absolute max DC emitter current; supports driving small relays, LEDs, or MOSFET gates directly from microcontroller GPIOs. |
| VCE(sat) | ≤ 0.3 V at IC = 10 mA / IB = 0.5 mA - low saturation voltage minimizes power loss and self-heating during on-state operation. |
| hFE | 120–630 - wide DC current gain range ensures reliable turn-on across process and temperature variation in production designs. |
| R1 | 4.7 kΩ ±23% (3.2–6.2 kΩ) - integrated base resistor sets fixed current gain and eliminates layout dependency for consistent switching thresholds. |
| fT | 150 MHz typ. - sufficient for high-speed digital switching up to ~10–20 MHz square-wave signals with minimal rise/fall time degradation. |
| Ccb | 3 pF max - low collector-base capacitance reduces Miller effect, supporting stable switching in moderate-frequency logic buffers. |
Pinout & Package
BCR 119L3 E6327 is housed in a standard SOT23 (TSFP-3) plastic surface-mount package with gull-wing leads, optimized for automated assembly and thermal dissipation via PCB copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base | Internal connection to R1; accepts logic-level input (Vi(on) = 0.5–1.1 V); no external resistor required. |
| 2 (E) | Emitter | Common reference node; tied to ground in low-side switch configurations; defines current return path. |
| 3 (C) | Collector | Switched output node; connects to load (e.g., LED anode, relay coil, gate of N-channel MOSFET). |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic R1 integration | 4.7 kΩ resistor fabricated on-die - eliminates one external component, reduces BOM count, and improves layout reproducibility. |
| Low VCE(sat) | ≤ 0.3 V at rated IC/IB - reduces conduction loss to <1.5 mW at 5 mA, critical for battery-powered sensor nodes. |
| High junction temperature rating | Tj = 150 °C - supports operation in enclosed enclosures or near heat sources without derating below 100 mA. |
| Thermal performance | RthJS ≤ 60 K/W - enables 250 mW total power dissipation at board temperature ≤135 °C, exceeding standard SOT23 limits. |
Applications
| LED Driver Circuit | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V MCU outputs in portable medical devices. IC Role / Device Role / Timing Role: Low-side switch controlled by GPIO; provides current-limited, logic-compatible on/off control. Use Value: Built-in R1 ensures consistent 0.5–1.1 V Vi(on) threshold across voltage and temperature, eliminating calibration overhead. | Use Scenario: Adding 8-bit parallel output capability to an STM32-based PLC module with limited GPIO availability. IC Role / Device Role / Timing Role: Digital buffer stage translating MCU port pins to higher-current loads (e.g., optocoupler inputs, small solenoids). Use Value: VCE(sat) ≤ 0.3 V guarantees <6 mW per channel at 20 mA, minimizing cumulative heating in dense 8-channel arrays. |
| Industrial Sensor Interface | Power Supply Enable Control |
Use Scenario: Level-shifting and isolating analog sensor enable signals (e.g., pressure transducer sleep/wake line) in 24 V fieldbus systems. IC Role / Device Role / Timing Role: Logic-level translator between 3.3 V sensor IC and 24 V supply rail; operates as open-collector compatible switch. Use Value: VCEO = 50 V allows safe operation with 24 V supply transients up to 40 V, meeting IEC 61000-4-4 surge immunity requirements. | Use Scenario: Enabling/disabling a 5 V LDO regulator in an automotive infotainment head unit based on ignition signal. IC Role / Device Role / Timing Role: High-side or low-side enable switch controlling LDO EN pin or input FET gate. Use Value: hFE ≥ 120 ensures full saturation with ≤0.5 mA base drive - compatible with weak-sink MCU pins and reduces MCU I/O loading. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR116L3 E6327 | Same SOT23 package, but R1 = 10 kΩ; hFE min = 160; VCE(sat) ≤ 0.3 V at IC = 5 mA/IB = 0.25 mA. | Higher input impedance; better suited for ultra-low-drive GPIOs or higher-VCC logic families (e.g., 5 V CMOS). | Select when base drive current must be ≤250 µA while maintaining saturation. |
| NSV11200MT1G | ON Semiconductor SOT23 NPN digital transistor; R1 = 4.7 kΩ; VCEO = 50 V; but hFE = 80–240 and RthJS = 125 K/W. | Lower gain and higher thermal resistance limit continuous current to ~60 mA at same board temperature. | Acceptable for cost-sensitive consumer designs where gain margin and thermal headroom are less critical. |
Compared with BCR119L3 E6327, BCR116L3 offers higher input impedance for weaker drivers, while NSV11200MT1G trades gain and thermal performance for broader distributor availability - making the BCR119L3 optimal for industrial designs requiring guaranteed 100 mA switching with minimal thermal derating.

FAQ
What is the exact pinout configuration of BCR 119L3 E6327?
The BCR 119L3 E6327 uses the SOT23 package with pin 1 = Base (connected to internal R₁), pin 2 = Emitter, and pin 3 = Collector. This matches the standard TSFP-3 mechanical outline and is verified in Infineon's 2005 datasheet revision, page 1, pin configuration diagram labeled "BCR119L3".
Does BCR 119L3 E6327 require an external base resistor?
No - it integrates a monolithic 4.7 kΩ base resistor (R₁) between the base terminal and internal transistor base region. This eliminates the need for an external resistor in standard switching applications, simplifying layout and improving consistency across production units.
Can BCR 119L3 E6327 drive a 100 mA load continuously?
Yes - at board temperature ≤135 °C, its rated Ptot = 250 mW supports IC = 100 mA with VCE(sat) ≤ 0.3 V (30 mW dissipation), leaving ample thermal margin. Derating is required above 135 °C per the Ptot vs. TS curve on datasheet page 5.
How does BCR 119L3 E6327 differ from BCR119S?
The BCR119L3 is a single-transistor SOT23 device, whereas BCR119S is a dual-transistor SOT363 package with matched characteristics. The L3 variant offers higher thermal efficiency (RthJS ≤ 60 K/W vs. 140 K/W for S), simpler routing, and lower cost per switch - ideal for single-channel applications.
