Product details
Overview
BCR 133F B6327 from Infineon Technologies is an NPN silicon digital transistor with integrated bias resistors (R1 = R2 = 10 kΩ), designed for low-power switching in interface, inverter, and driver circuits. It supports 50 V VCEO, 100 mA IC, 0.3 V VCE(sat) at IC/IB = 20, operates up to 150 °C junction temperature, and is AEC-Q101 qualified for automotive applications.
For engineers reviewing the BCR 133F B6327 datasheet, BCR 133F B6327 pinout, BCR 133F B6327 application, or BCR 133F B6327 equivalent, key selection criteria include built-in resistor matching, thermal resistance (RthJS ≤ 240 K/W), SOT23 package compatibility, and guaranteed Vi(on)/Vi(off) thresholds for reliable logic-level interfacing.
Technical Context
This digital transistor integrates two matched 10 kΩ bias resistors to enable single-pin logic-level control without external components. Its internal resistor ratio (R1/R2 = 0.9–1.1) ensures stable DC current gain (hFE ≥ 30 at IC = 5 mA) across temperature.
The device uses a common-emitter configuration with defined VCE(sat) ≤ 0.3 V and transition frequency fT ≥ 130 MHz, supporting fast switching in 5 V digital systems while maintaining low power dissipation (Ptot = 200 mW at TS ≤ 102 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown in switching applications |
| IC | 100 mA - Continuous collector current handling capacity for drive and interface loads |
| VCE(sat) | ≤ 0.3 V at IC = 10 mA, IB = 0.5 mA - Ensures minimal conduction loss and heat generation |
| R1 / R2 | 10 kΩ ±30% each, ratio 0.9–1.1 - Enables predictable turn-on/off thresholds without external tuning |
| fT | ≥ 130 MHz - Supports high-speed digital switching up to ~10 MHz square-wave operation |
| Tj max | 150 °C - Allows operation in under-hood automotive environments with derated power |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronic components |

BCR 133F B6327 is housed in a Pb-free, RoHS-compliant SOT23 plastic package (JEDEC TO-236AB), with standard 3-pin layout optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base connection | Input node for logic-level control; internally connected to R1 and R2 network |
| 2 (E) | Emiter connection | Common emitter reference; tied to ground or low-side return path in switch topology |
| 3 (C) | Collector connection | Output node driving load; supports up to 50 V and 100 mA continuous current |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Dual 10 kΩ resistors eliminate need for external base pull-up/pull-down components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BW | Standard NPN BJT without built-in resistors; requires external base bias network | Higher design flexibility but increases component count and layout area | Select when precise bias tuning or variable gain is required beyond fixed-resistor topology |
| NSVD120DP03MX | PNP digital transistor with R1 = 4.7 kΩ, R2 = 4.7 kΩ; complementary polarity | Used for high-side switching where load connects to VCC, not ground | Select for sourcing current instead of sinking, e.g., active-low enable lines or LED anode drive |
Compared with BC847BW and NSVD120DP03MX, BCR 133F B6327 uniquely delivers integrated, matched biasing in an NPN configuration-reducing footprint and assembly cost for fixed-threshold, low-side switching where simplicity and AEC-Q101 compliance are critical.

FAQ
What is the maximum allowable base drive current for BCR 133F B6327?
The device does not specify a maximum base current rating, but its internal R1 and R2 resistors limit base current to ≤ 0.5 mA when driven from a 5 V logic source. Exceeding this may cause excessive power dissipation in the resistors or degrade long-term reliability. For higher drive needs, external buffering is recommended.
Can BCR 133F B6327 be used in linear amplifier mode?
No - BCR 133F B6327 is optimized for saturated switching operation, not analog amplification. Its built-in resistors fix the base bias point, and hFE is only specified under switching conditions (IC = 5 mA, VCE = 5 V). Linear use would result in unpredictable gain and thermal instability.
Is the SOT23 package of BCR 133F B6327 compatible with standard pick-and-place equipment?
Yes - the SOT23 outline conforms to JEDEC TO-236AB standards, with 0.95 mm lead pitch, 1.3 mm body width, and 2.9 mm length. It is fully supported by mainstream placement machines and reflow profiles for lead-free soldering, including IPC-7351B footprint recommendations.
Does BCR 133F B6327 support bidirectional signal translation?
No - it is a unidirectional NPN switch configured for low-side current sinking only. The internal resistor network and emitter-grounded topology prevent reverse conduction or level-shifting in the opposite direction. For bidirectional isolation, discrete optocouplers or dedicated level translators are required.
