Product details
Overview
BCR 191L3 E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = R2 = 22 kΩ), designed for switching, inverting, interfacing, and driver circuits in compact consumer and industrial control systems. It features VCEO = 50 V, IC = 100 mA, VCE(sat) ≤ 0.3 V at IC = 10 mA/IB = 0.5 mA, hFE ≥ 50, and operates up to Tj = 150 °C.
For engineers reviewing the BCR 191L3 E6327 datasheet, BCR 191L3 E6327 pinout, BCR 191L3 E6327 application, or BCR 191L3 E6327 equivalent, key selection considerations include its SOT23-3 package, built-in dual 22 kΩ bias resistors, guaranteed Vi(off) ≤ 1.5 V and Vi(on) ≥ 1 V, and thermal resistance RthJS ≤ 60 K/W enabling high-density PCB layouts.
Technical Context
This digital transistor integrates two matched 22 kΩ base bias resistors (R1, R2) to enable direct logic-level drive without external components. Its PNP topology supports active-low switching and level translation in microcontroller I/O interfaces.
It delivers stable DC current gain (hFE ≥ 50 at IC = 5 mA/VCE = 5 V) and low saturation voltage (VCE(sat) ≤ 0.3 V), ensuring efficient power delivery in load-driving applications while maintaining predictable turn-off behavior via Vi(off) ≤ 1.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter blocking voltage for safe operation in 24 V and 36 V control rails |
| IC | 100 mA - Continuous collector current rating suitable for driving LEDs, relays, and small solenoids |
| VCE(sat) | ≤ 0.3 V @ IC=10 mA/IB=0.5 mA - Low conduction loss minimizes heat generation in high-duty-cycle switching |
| hFE | ≥ 50 @ IC=5 mA/VCE=5 V - Predictable current amplification enables reliable gate/base drive design |
| R1 / R2 | 22 kΩ ±25% - Integrated bias network eliminates two external resistors, reducing BOM count and layout area |
| RthJS | ≤ 60 K/W - Enables higher power dissipation (250 mW) at board-level junction temperatures up to 135 °C |
| fT | 200 MHz typ. - Supports fast switching in PWM-driven loads up to ~100 kHz with minimal delay |
Pinout & Package

| High-temperature capability | Rated for TS ≤ 135 °C and Tj ≤ 150 °C - supports operation in enclosed industrial enclosures |
| Logic-compatible input thresholds | Vi(on) ≥ 1 V and Vi(off) ≤ 1.5 V match standard 3.3 V and 5 V CMOS/TTL output levels |
| Fast transition frequency | fT = 200 MHz enables clean edge response in PWM and pulse-width modulated drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR193L3 E6327 | Same package and pinout; hFE min = 100 (vs. 50), R1/R2 = 47 kΩ/47 kΩ | Higher gain and higher input impedance suit lower-drive GPIOs; slightly slower turn-off due to larger R values | Select when driving ultra-low-current loads or minimizing base current draw from weak drivers |
| NSV1913LT1G | PNP digital transistor in SOT-23; R1/R2 = 22 kΩ/22 kΩ but VCEO = 40 V (vs. 50 V), RthJS = 100 K/W | Limited to ≤40 V rails; lower thermal performance restricts use in thermally constrained designs | Acceptable only in cost-sensitive 24 V systems where 10 V margin is acceptable and board-level cooling is assured |

FAQ
What is the maximum continuous collector current for BCR 191L3 E6327?
The maximum continuous collector current is 100 mA at TS ≤ 135 °C. Derating applies above this temperature: power dissipation drops linearly to zero at 150 °C junction temperature. This rating assumes proper PCB copper pour and thermal vias for heat transfer.
Does BCR 191L3 E6327 require external base resistors?
No. It integrates two 22 kΩ bias resistors (R1 and R2) internally, forming a voltage divider that sets the base bias point. This eliminates the need for external resistors in standard switching configurations, simplifying schematic capture and layout.
Can BCR 191L3 E6327 be used as a high-side switch?
Yes. As a PNP transistor, it functions as a high-side switch when the emitter connects to the positive supply and the collector drives the load to ground. Its VCEO = 50 V and VCE(sat) ≤ 0.3 V make it suitable for 24 V and 36 V rail applications with appropriate load sizing.
What is the meaning of "L3" in BCR 191L3 E6327?
"L3" denotes the specific package variant: SOT23-3 (JEDEC TO-236AB) with lead finish matte tin, qualified for reflow soldering per J-STD-020. It distinguishes this version from other BCR191 variants like BCR191F (TSFP-3) and BCR191T (SC75).
