Product details
Overview
BCR 151L3 E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 100 kΩ), designed for low-power switching, interface, and driver circuits in compact consumer and industrial electronics. It features VCEO = 50 V, IC = 50 mA, VCE(sat) ≤ 0.3 V at IC = 5 mA/IB = 0.25 mA, hFE ≥ 70, and operates up to Tj = 150 °C in SC75 package.
For engineers reviewing the BCR 151L3 E6327 datasheet, BCR 151L3 E6327 pinout, BCR 151L3 E6327 application, or BCR 151L3 E6327 equivalent, this part serves as a space-optimized, resistor-equipped PNP switch for logic-level interfacing, LED driving, and microcontroller I/O buffering where simplified biasing and predictable turn-on/off thresholds are required.
Technical Context
This digital transistor integrates two matched 100 kΩ bias resistors (R1 from base to emitter, R2 from base to collector) to enable single-resistor external drive-eliminating discrete base bias components. Its common-emitter configuration supports direct TTL/CMOS logic interfacing without level-shifting.
The SC75 package delivers low thermal resistance (RthJS ≤ 60 K/W), enabling stable operation at 250 mW total dissipation up to 135 °C case temperature. AC performance includes fT = 120 MHz and Ccb = 3 pF, supporting fast switching in signal routing and pulse generation applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown under open-base conditions |
| IC | 50 mA - Continuous collector current rating defining maximum load drive capability |
| VCE(sat) | ≤ 0.3 V at IC = 5 mA / IB = 0.25 mA - Low saturation voltage ensures minimal power loss during on-state |
| hFE | ≥ 70 at IC = 5 mA / VCE = 5 V - Sufficient DC gain for reliable switching with low base drive current |
| R1, R2 | 100 kΩ ±30% - Integrated bias resistors enable direct logic-level control without external components |
| fT | 120 MHz - Transition frequency supports switching speeds up to ~10–20 MHz in practical circuits |
| RthJS | ≤ 60 K/W - Junction-to-solder-point thermal resistance enables higher power handling in SC75 footprint |
Pinout & Package
BCR 151L3 E6327 is housed in the SC75 (SOT-416) surface-mount package: 1.6 mm × 0.8 mm × 0.5 mm, 3-pin, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base connection point | Internally tied to both R1 and R2; accepts logic-level input to control switching state |
| 2 (E) | Emitter terminal | Common reference node for PNP operation; connects to higher potential rail in high-side switch configurations |
| 3 (C) | Collector terminal | Output node sourcing current when active; used for driving LEDs, relays, or logic inputs |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual bias resistors | R1 = R2 = 100 kΩ ±30%, eliminating external base resistors and reducing PCB area |
| Low VCE(sat) | ≤ 0.3 V ensures <1.5 mW conduction loss at 5 mA, critical for battery-powered interfaces |
| High hFE consistency | Min. 70 at standard test conditions enables robust switching across process and temperature variation |
| SC75 thermal performance | RthJS ≤ 60 K/W allows 250 mW dissipation up to 135 °C case temperature |
Applications
| LED Driver Circuit | Microcontroller I/O Buffer |
|---|---|
Use Scenario: Driving indicator LEDs from 3.3 V or 5 V MCU GPIO pins with current limiting via collector load. IC Role / Device Role / Timing Role: PNP digital transistor acting as high-side current sink with built-in bias network. Use Value: Eliminates need for two external resistors per LED channel, reducing BOM count and layout complexity. | Use Scenario: Level-shifting and current amplification between low-drive MCU outputs and higher-current peripheral inputs. IC Role / Device Role / Timing Role: Logic-compatible interface device converting weak GPIO signals into robust 50 mA capable outputs. Use Value: Ensures clean signal integrity and noise immunity while maintaining sub-1 µs switching transitions. |
| Low-Power Inverter | Push-Pull Interface Stage |
Use Scenario: Inverting logic signals in portable audio codecs or sensor signal conditioning paths. IC Role / Device Role / Timing Role: Single-transistor inverter with defined Vi(on)/Vi(off) thresholds (1–3 V / 0.5–1.8 V). Use Value: Predictable switching thresholds reduce susceptibility to supply ripple and improve noise margin over discrete designs. | Use Scenario: Complementing NPN digital transistors (e.g., BCR141) in complementary output stages for bidirectional bus drivers. IC Role / Device Role / Timing Role: PNP half of push-pull pair providing active pull-up capability in open-collector systems. Use Value: Matched R1/R2 ratio (0.9–1.1) ensures symmetrical rise/fall times and reduced crossover distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR152L3 E6327 | NPN polarity; identical R1/R2 values, package, and ratings except VCEO and current direction | Used where low-side switching or sink configuration is preferred over high-side source | Select when circuit topology requires NPN logic inversion or ground-referenced load switching |
| NSV151L3T1G | Same SC75 package and function but with tighter R1/R2 tolerance (±10%) and lower VCE(sat) (≤ 0.25 V) | Suitable for higher-efficiency or precision threshold applications requiring tighter bias matching | Choose when improved thermal stability or reduced conduction loss justifies minor cost increase |
Compared with BCR 151L3 E6327, the BCR152L3 offers complementary NPN functionality in identical form factor, while NSV151L3T1G provides enhanced precision and efficiency-making the original optimal for cost-sensitive, high-volume PNP interface roles where ±30% resistor tolerance is acceptable.

FAQ
What is the pin configuration of BCR 151L3 E6327?
Pin 1 is Base (B), Pin 2 is Emitter (E), and Pin 3 is Collector (C), arranged left-to-right in the SC75 package with marking dot adjacent to Pin 1. This matches the standard SC75 pinout used across Infineon's digital transistor family and is verified in the official package outline drawing.
Does BCR 151L3 E6327 require an external base resistor?
No. It integrates R1 (base-to-emitter) and R2 (base-to-collector) resistors, each nominally 100 kΩ, enabling direct connection to logic outputs. External biasing is unnecessary unless specific threshold adjustment or higher-speed operation demands modified resistor values.
What is the maximum operating temperature for continuous use?
The junction temperature limit is 150 °C, and the package supports 250 mW total power dissipation up to a case temperature (TS) of 135 °C. Derating is required above that point per the published Ptot vs. TS curve in the datasheet.
Can BCR 151L3 E6327 replace a standard PNP BJT like BC807?
It can substitute in switching roles but not as a general-purpose amplifier due to fixed internal resistors and optimized saturation characteristics. Designers must verify that the built-in bias network meets the required input threshold and drive strength-especially for non-logic-level control sources.
