Product details
Overview
BCR 119 E6433 from Infineon Technologies is an NPN silicon digital transistor with integrated 4.7 kΩ base resistor, designed for switching, inverter, 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 BCR 119 E6433 datasheet, BCR 119 E6433 pinout, BCR 119 E6433 application, or BCR 119 E6433 equivalent, this part serves as a single-element, RoHS-compliant, SOT23-packaged digital transistor optimized for low-power logic-level interfacing and load switching with built-in biasing.
Technical Context
This device integrates a monolithic NPN transistor with a precision 4.7 kΩ input resistor (R1 = 3.2–6.2 kΩ), enabling direct TTL/CMOS logic-level drive without external bias components. Its common-emitter configuration supports DC switching with guaranteed Vi(on) ≤ 1.1 V and Vi(off) ≥ 0.4 V at specified test conditions.
Thermal performance is defined by RthJS ≤ 240 K/W (SOT23), junction temperature up to 150 °C, and pulse operation support per duty cycle and pulse width curves. It operates across –65 °C to +150 °C storage range and meets automotive reliability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive and 3.3/5 V logic-driven 48 V subsystems. |
| IE | 100 mA - Absolute maximum DC emitter current; suitable for driving LEDs, small relays, and MOSFET gates. |
| hFE | 120–630 - DC current gain at IC = 5 mA/VCE = 5 V; ensures reliable saturation under varying temperature and process conditions. |
| VCE(sat) | ≤ 0.3 V - Low saturation voltage at IC = 10 mA/IB = 0.5 mA; minimizes power loss and self-heating in switching mode. |
| R1 | 4.7 kΩ (3.2–6.2 kΩ) - Integrated base resistor; eliminates need for external bias network in standard logic-to-transistor interfaces. |
| fT | 150 MHz - Transition frequency at IC = 10 mA/VCE = 5 V; supports fast edge transitions in digital signal routing. |
| Ptot | 200 mW - Total power dissipation at TS ≤ 102 °C (SOT23); defines thermal derating envelope for PCB layout planning. |
Pinout & Package
BCR 119 E6433 is housed in a Pb-free, RoHS-compliant SOT23 package (JEDEC TO-236AB), with standardized 3-pin lead frame and 1.3 mm pitch. Pin 1 = Base (B), Pin 2 = Emitter (E), Pin 3 = Collector (C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Input terminal with internal R1 connection | Accepts logic-level input; R1 provides current-limited base drive-no external resistor required for TTL/CMOS compatibility. |
| 2 (E) | Emitting terminal / reference node | Connected to system ground or low-side return path; forms common-emitter switching node with collector output. |
| 3 (C) | Output terminal / switched load connection | Drives resistive, inductive, or capacitive loads; rated for 50 V and 100 mA continuous DC operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated base resistor | 4.7 kΩ ±30% - Enables direct logic-level drive without external bias components, reducing BOM count and layout area. |
| AEC-Q101 qualification | Qualified for automotive applications - guarantees reliability under temperature cycling, humidity, and mechanical stress per automotive grade requirements. |
| Low VCE(sat) | ≤ 0.3 V at IC/IB = 20 - Ensures minimal conduction loss and stable on-state behavior across operating temperature range (–40 °C to +125 °C). |
| High fT | 150 MHz - Supports clean switching of digital signals up to ~10–15 MHz with controlled rise/fall times. |
Applications

Use Value: Low ICEO and IEBO (<100 nA) minimize standby leakage; RoHS-compliant packaging meets environmental certification for IoT deployments. |
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) | Standard NPN BJT without integrated resistor; requires external base bias network. | Used where adjustable gain or precise biasing is needed; not drop-in for logic-driven switching. | Select when design requires tunable hFE or multi-stage amplification-not for direct logic interface. |
| MMBT3904LT1G (ON Semiconductor) | General-purpose NPN transistor; no built-in resistor; higher VCEO (40 V) but lower max IE (200 mA). | Common in non-automotive consumer electronics; lacks AEC-Q101 qualification and integrated R1. | Choose for cost-sensitive, non-automotive applications where external biasing is acceptable and qualification is not required. |
Compared with BC847B and MMBT3904LT1G, BCR 119 E6433 delivers plug-and-play logic interfacing with guaranteed Vi(on)/Vi(off), automotive qualification, and reduced component count-making it optimal for space-constrained, high-reliability switching where base resistor integration adds value.

FAQ
Is BCR 119 E6433 pin-compatible with standard SOT23 NPN transistors like BC847?
No. While both use SOT23 packages, BCR 119 E6433 has Pin 1 = Base (with internal resistor), Pin 2 = Emitter, Pin 3 = Collector. Standard BC847 variants use Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector. Physical pinout differs, and electrical behavior is not interchangeable without circuit redesign.
What is the maximum allowable input voltage at the base terminal (Pin 1)?
The absolute maximum input voltage at Pin 1 is limited by Vi(rev) = 5 V (reverse) and Vi(fwd) = 30 V (forward). For safe operation, keep input voltage within 0–5 V for logic-level drive; exceeding 5 V forward risks damaging the integrated resistor or junction.
Does BCR 119 E6433 support PWM switching at frequencies above 10 kHz?
Yes. With fT = 150 MHz and VCE(sat) stable up to 125 °C, it supports PWM switching well beyond 10 kHz. Measured VCE(sat) vs. IC curves confirm consistent on-state behavior up to at least 50 kHz under typical load conditions and thermal limits.
Can BCR 119 E6433 replace a discrete BJT + resistor pair in an existing design?
Yes-if the original design uses an NPN transistor with ~4.7 kΩ base resistor and operates within VCEO ≤ 50 V and IE ≤ 100 mA. Verify pinout alignment (SOT23 base-first vs. emitter-first), ensure thermal margin given Ptot = 200 mW, and confirm logic thresholds match Vi(on)/Vi(off) specs.
