Product details
Overview
BCR119E6327HTSA1 from Infineon Technologies is an NPN silicon digital transistor with integrated 4.7 kΩ base resistor, designed for switching, inverting, interface, and driver circuits in automotive and industrial control systems. It features VCEO = 50 V, IE = 100 mA, hFE = 120–630, VCE(sat) ≤ 0.3 V at IC = 10 mA/IB = 0.5 mA, and is AEC-Q101 qualified.
For engineers reviewing the BCR119E6327HTSA1 datasheet, BCR119E6327HTSA1 pinout, BCR119E6327HTSA1 application, or BCR119E6327HTSA1 equivalent, key selection criteria include built-in bias resistor value, saturation voltage under defined drive conditions, thermal resistance (RthJS ≤ 240 K/W), junction temperature rating (Tj = 150 °C), and automotive qualification status.
Technical Context
This device integrates a single NPN transistor with monolithically embedded R1 = 4.7 kΩ base resistor, enabling direct logic-level interfacing without external bias components. Its SOT23 package supports surface-mount assembly and delivers stable DC current gain (hFE) across −40 °C to 125 °C.
The transistor operates in common-emitter configuration with guaranteed VCE(sat) ≤ 0.3 V at IC/IB = 20, Vi(on) = 0.5–1.1 V, and Vi(off) = 0.4–0.8 V - parameters critical for reliable low-voltage digital switching in microcontroller-driven loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum collector-emitter voltage before breakdown; enables use in 24 V automotive and industrial supply rails. |
| IE | 100 mA - absolute max DC emitter current; defines upper limit for driving relays, LEDs, or small solenoids. |
| hFE | 120–630 - DC current gain at IC = 5 mA/VCE = 5 V; ensures robust switching margin with TTL/CMOS logic drive. |
| VCE(sat) | ≤ 0.3 V at IC = 10 mA/IB = 0.5 mA - low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| R1 | 4.7 kΩ (typ), 3.2–6.2 kΩ (min–max) - integrated base resistor simplifies PCB layout and eliminates discrete bias network. |
| fT | 150 MHz (typ) - transition frequency supports fast edge rates in pulse-width modulation and signal inversion up to ~10 MHz. |
| Tj | 150 °C - maximum junction temperature; allows operation in under-hood or enclosed industrial enclosures without derating. |
Pinout & Package
SOT23-3 package: compact, surface-mount, thermally efficient plastic case with gull-wing leads; JEDEC standard footprint; RoHS-compliant, Pb-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base | Connected internally to R1; accepts logic-level input (Vi(on)/Vi(off) thresholds defined); no external base resistor required. |
| 2 (E) | Emitter | Common reference node for input and output paths; tied to system ground in low-side switch configurations. |
| 3 (C) | Collector | Switched output node; connects to load (e.g., relay coil, LED anode); handles up to 100 mA DC current. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated base resistor | R1 = 4.7 kΩ ±22% enables direct connection to 3.3 V/5 V MCU GPIOs without external components. |
| AEC-Q101 qualification | Validated for automotive applications including body electronics, lighting control, and engine management subsystems. |
| Low VCE(sat) | ≤ 0.3 V at rated IC/IB reduces conduction loss by >40% vs. standard transistors without optimized base drive. |
| Wide temperature range | Guaranteed electrical performance from −40 °C to +125 °C ambient; supports operation in harsh environments. |
| High fT | 150 MHz typical enables clean square-wave switching in PWM dimming and digital signal buffering up to 10 MHz. |
Applications
| Automotive LED Headlamp Control | Industrial PLC Digital Output Module |
|---|---|
Use Scenario: Driving high-brightness LED strings in adaptive front-lighting systems with PWM dimming. IC Role / Device Role / Timing Role: Low-side switch controlled by MCU PWM signal; provides current path to ground for LED cathodes. Use Value: Integrated R1 eliminates external bias resistor; low VCE(sat) limits heat rise during 100% duty cycle operation. |
Use Scenario: Isolating and amplifying 24 V DC digital outputs from programmable logic controller backplanes. IC Role / Device Role / Timing Role: Interface buffer between low-voltage logic and industrial field-side loads (solenoids, indicators). Use Value: AEC-Q101 qualification ensures reliability in vibration-prone cabinet environments; 50 V VCEO accommodates inductive kickback. |
| Consumer Appliance Motor Driver Stage | IoT Sensor Node Power Switching |
Use Scenario: Enabling/disabling small DC brush motors in smart home appliances (e.g., coffee grinders, air purifiers). IC Role / Device Role / Timing Role: Single-stage switch activated by microcontroller GPIO; handles bidirectional motor current via H-bridge companion devices. Use Value: 100 mA IE rating matches typical motor stall currents; SOT23 footprint saves board space in compact enclosures. |
Use Scenario: Controlling power to peripheral sensors (e.g., temperature, humidity) in battery-powered edge nodes. IC Role / Device Role / Timing Role: Load switch managing VDD rail to sensor ICs; turned on/off by ultra-low-power MCU wake-up signals. Use Value: Vi(off) ≤ 0.8 V ensures full cutoff with weak pull-ups; low leakage (IEBO ≤ 100 nA) preserves battery life over long sleep cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B,115 (Nexperia) | Discrete NPN BJT without built-in resistor; requires external base bias network. | Used where adjustable gain or variable switching threshold is needed; not drop-in compatible. | Select when precise hFE control or multi-current operating points are required. |
| NSV11901T1G (onsemi) | Same SOT23-3 package, AEC-Q101 qualified, but R1 = 10 kΩ and VCE(sat) ≤ 0.25 V at lower IB. | Better suited for 1.8 V/2.5 V logic interfaces; slightly higher input threshold may reduce noise immunity. | Prefer for ultra-low-voltage MCU interfaces where tighter VCE(sat) and higher R1 improve noise margin. |
Compared with BC847B,115 and NSV11901T1G, BCR119E6327HTSA1 offers optimal balance of standardized 4.7 kΩ bias, proven 5 V logic compatibility, and automotive-grade reliability - making it ideal for cost-sensitive, high-volume automotive and industrial switching where design simplicity and qualification are primary drivers.

FAQ
Is BCR119E6327HTSA1 suitable for 3.3 V microcontroller GPIO drive?
Yes. With Vi(on) specified from 0.5 V to 1.1 V at IC = 2 mA, the device reliably switches on using standard 3.3 V CMOS logic outputs. Its integrated 4.7 kΩ base resistor ensures sufficient base current without external components, and VCE(sat) remains ≤ 0.3 V under these conditions.
What is the thermal resistance RthJS and how does it affect PCB layout?
RthJS is ≤ 240 K/W for the SOT23 package, measured from junction to soldering point. This value assumes standard JEDEC PCB pad layout per datasheet AN2007-08-02. To maintain Tj ≤ 150 °C, keep copper area around pin 2 (emitter) ≥ 25 mm² and avoid thermal isolation of the SOT23 pad.
Does BCR119E6327HTSA1 support PWM switching above 1 kHz?
Yes. With fT = 150 MHz and VCE(sat) stable up to 125 °C, the device supports PWM frequencies up to 10 MHz in low-duty-cycle applications. For continuous 100% duty cycle at 100 mA, thermal derating applies per the Ptot vs. TS curve (200 mW at TS ≤ 102 °C).
How does the AEC-Q101 qualification impact its use in non-automotive designs?
AEC-Q101 qualification confirms extended temperature operation (−40 °C to +125 °C), mechanical robustness (vibration/shock), and process reliability - all beneficial for industrial, medical, and outdoor equipment. It does not restrict usage; rather, it provides assurance of enhanced quality and longevity beyond standard commercial-grade parts.
