Product details

Overview

BCR 189F E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistor (R1 = 22 kΩ), designed for low-power switching, interface, and driver circuits. It features V_CEO = 50 V, I_C = 100 mA, V_CE(sat) ≤ 0.3 V at I_C = 10 mA/I_B = 0.5 mA, h_FE = 120–630, and operates up to T_j = 150 °C in SC75 (TSLP-3) package.

For engineers reviewing the BCR 189F E6327 datasheet, BCR 189F E6327 pinout, BCR 189F E6327 application, or BCR 189F E6327 equivalent, key selection criteria include built-in R1 value, guaranteed V_CE(sat) under defined drive conditions, thermal resistance (R_thJS ≤ 90 K/W), DC current gain range, and SC75 footprint compatibility for space-constrained PCB layouts.

Technical Context

This digital transistor integrates a single 22 kΩ base bias resistor (R1) to simplify external component count in saturated-switch configurations. Its PNP topology enables high-side switching with logic-level input control, and its f_T = 200 MHz supports fast edge transitions in signal routing and level-shifting applications.

The device operates in common-emitter configuration with guaranteed V_(BR)EBO = 5 V and V_(BR)CEO = 50 V, ensuring robustness against transient overvoltage on emitter and collector nodes. Thermal derating curves confirm stable operation up to 128 °C case temperature with P_tot = 250 mW at T_S ≤ 128 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum allowable collector-emitter voltage before breakdown; defines safe operating voltage headroom in 24 V or 36 V rail switching.
I_C	100 mA - Continuous collector current rating; suitable for driving LEDs, small relays, or logic inputs without external heat sinking.
V_CE(sat)	≤ 0.3 V @ I_C=10 mA/I_B=0.5 mA - Low saturation voltage minimizes power loss and self-heating during ON-state operation.
h_FE	120–630 @ I_C=5 mA/V_CE=5 V - Wide DC current gain range ensures reliable turn-on across process and temperature variation.
R1	22 kΩ (typ.) - Integrated base bias resistor eliminates need for external pull-up/pull-down, reducing BOM count and layout area.
f_T	200 MHz - Transition frequency supports clean switching of digital signals up to ~20 MHz with minimal rise/fall time degradation.
R_thJS	≤ 90 K/W - Junction-to-solder-point thermal resistance enables predictable thermal design for reflow-soldered SC75 footprints.

Pinout & Package

BCR 189F E6327 is housed in the SC75 (TSLP-3) surface-mount package: 1.6 mm × 0.8 mm × 0.45 mm, 3-pin, lead-free, RoHS-compliant, with gull-wing leads and pin 1 marked by chamfer.

Pin/Terminal	Circuit Role	Design Meaning
1 (B)	Base	Connected internally to R1; accepts logic-level input (Vi(on) = 0.5–1.1 V) to enable saturation switching.
2 (E)	Emitter	PNP emitter node; tied to higher potential rail (e.g., V_CC) in high-side switch configurations.
3 (C)	Collector	Output node; sinks load current to ground when transistor is ON; rated for 50 V and 100 mA continuous.

Key Features

Feature	Design Value
Integrated bias resistor	R1 = 22 kΩ ±25% - Eliminates external base resistor, reduces PCB area, and improves assembly yield.
Guaranteed saturation performance	V_CE(sat) ≤ 0.3 V @ specified I_B/I_C - Ensures predictable low-loss switching without iterative bias tuning.
High DC current gain	h_FE ≥ 120 @ I_C = 5 mA - Enables sufficient drive margin even at low base currents or elevated temperature.
Fast switching capability	f_T = 200 MHz - Supports clean digital waveform integrity in interface and pulse-width modulation (PWM) applications.
Thermally optimized package	R_thJS ≤ 90 K/W - Allows direct thermal modeling from junction to solder joint for reliability analysis.

Applications

LED Driver Circuit

Microcontroller Interface

Use Scenario: Driving 20 mA indicator LEDs from 3.3 V or 5 V microcontroller GPIO pins.

IC Role / Device Role / Timing Role: PNP digital transistor acting as low-side sink switch with logic-inverted control.

Use Value: Built-in R1 ensures correct base drive without external components; V_CE(sat) ≤ 0.3 V keeps LED forward voltage drop stable and power loss below 6 mW.

Use Scenario: Level-shifting and signal inversion between mixed-voltage logic domains (e.g., 1.8 V FPGA output to 5 V peripheral input).

IC Role / Device Role / Timing Role: Single-transistor inverter with fixed bias, providing rail-to-rail logic swing and <10 ns propagation delay.

Use Value: f_T = 200 MHz and low C_cb = 3 pF minimize signal distortion; guaranteed h_FE ensures consistent fan-out across temperature.

Relay Driver Stage

Power Rail Sequencing

Use Scenario: Controlling 5 V/100 mA coil relays in industrial I/O modules using 3.3 V MCU outputs.

IC Role / Device Role / Timing Role: High-side switch enabling relay activation when MCU pin is LOW.

Use Value: V_CEO = 50 V provides 10 V margin above 40 V relay flyback spikes; R_thJS ≤ 90 K/W prevents thermal runaway during sustained 100 ms actuation pulses.

Use Scenario: Enabling 12 V auxiliary rails only after main 5 V supply stabilizes in embedded power management.

IC Role / Device Role / Timing Role: Delayed-enable switch controlled by RC-filtered reset signal.

Use Value: Vi(off) ≤ 0.8 V ensures full cutoff during reset assertion; V_(BR)EBO = 5 V tolerates noise on enable line without leakage-induced false turn-on.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP digital transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCR190F E6327	Same SC75 package, but NPN polarity; R1 = 47 kΩ; V_CEO = 50 V; I_C = 100 mA.	Requires inverted logic control and low-side load placement instead of high-side.	Select when circuit topology mandates NPN configuration or when existing layout uses complementary drive pairs.
NSV189FDT5G	PNP digital transistor in SOT-416 (SC75) package; R1 = 22 kΩ; V_CEO = 50 V; I_C = 100 mA; V_CE(sat) ≤ 0.25 V @ same conditions.	Identical pinout and function; slightly lower V_CE(sat) improves efficiency in high-duty-cycle switching.	Prefer for thermally sensitive designs where sub-0.25 V saturation is required, with no layout change needed.

Compared with BCR189F E6327, BCR190F E6327 offers polarity reversal for NPN-based topologies, while NSV189FDT5G delivers marginally better saturation voltage in identical form factor-both retain SC75 compatibility and 22 kΩ biasing for seamless integration into existing driver stages.

FAQ

What is the maximum allowable continuous collector current for BCR 189F E6327?

The absolute maximum continuous collector current (I_C) is 100 mA at T_S ≤ 128 °C. Derating applies above this case temperature per the P_tot vs. T_S curve; at 150 °C junction temperature, usable I_C drops to approximately 65 mA assuming typical V_CE(sat).

Does BCR 189F E6327 require an external base resistor?

No. BCR 189F E6327 integrates a monolithic 22 kΩ base bias resistor (R1) between the base terminal and internal transistor base. This eliminates the need for an external resistor in standard saturated-switch configurations driven by logic-level voltages.

Is BCR 189F E6327 compatible with lead-free reflow soldering processes?

Yes. The device is qualified for lead-free reflow per JEDEC J-STD-020, with peak reflow temperature up to 260 °C. Its SC75 (TSLP-3) package uses matte tin-plated terminals and meets RoHS Directive 2011/65/EU requirements.

How does the built-in R1 value affect input threshold behavior?

The 22 kΩ R1 sets the effective input impedance and defines Vi(on) (0.5–1.1 V) and Vi(off) (0.4–0.8 V) thresholds. At V_IN > 1.1 V, the transistor saturates fully; below 0.4 V, it remains reliably cut off-enabling robust noise immunity in noisy industrial environments.
