Product details
Overview
BCR 569 E6327 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistors (R1 = 4.7 kΩ), designed for switching, inverter, interface, and driver circuits. It features VCEO = 50 V, IC = 500 mA, hFE = 630 (typ.), VCE(sat) = 0.3 V at IC = 50 mA / IB = 2.5 mA, and fT = 150 MHz - used in automotive body control modules for LED load switching.
For engineers reviewing the BCR 569 E6327 datasheet, BCR 569 E6327 pinout, BCR 569 E6327 application, or BCR 569 E6327 equivalent, key selection criteria include built-in R1 resistor value, guaranteed hFE minimum at IC = 50 mA, VCE(sat) compliance under pulsed loads, and SOT23 thermal resistance (RthJS = 215 K/W).
Technical Context
This digital transistor integrates a single 4.7 kΩ base-emitter pull-up resistor (R1) to enable direct logic-level drive without external bias components. Its PNP topology supports high-side switching configurations where emitter connects to supply rail and collector drives grounded loads.
Designed for DC and low-frequency switching (fT = 150 MHz confirms adequate bandwidth for PWM up to ~100 kHz), it operates within Tj = –65 °C to 150 °C and delivers stable hFE across IC = 1 mA–100 mA per characterization curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum allowable collector-emitter voltage before breakdown in common-emitter configuration |
| IC | 500 mA - absolute maximum continuous collector current; derated above TS = 79 °C |
| hFE | 630 (max) at IC = 50 mA, VCE = 5 V - ensures sufficient current gain for reliable saturation with low base drive |
| VCE(sat) | 0.3 V (typ.) at IC = 50 mA, IB = 2.5 mA - enables <150 mW conduction loss in 5 V logic-driven loads |
| R1 | 4.7 kΩ - internal base resistor allows direct connection to 3.3 V/5 V microcontroller GPIOs |
| fT | 150 MHz - transition frequency confirming suitability for fast-switching applications up to ~100 kHz PWM |
| Ptot | 330 mW at TS = 79 °C - defines thermal limit for PCB-mounted operation without heatsink |
Pinout & Package
SOT23 plastic surface-mount package with gull-wing leads; compact footprint (2.9 × 1.3 × 1.0 mm) optimized for automated assembly and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Base terminal with integrated R1 resistor | Connected internally to 4.7 kΩ resistor; accepts logic-level input directly from MCU |
| 2 (E) | Emitter terminal | High-side connection point; ties to positive supply rail in typical switch configuration |
| 3 (C) | Collector terminal | Switched output node; drives grounded loads such as LEDs, relays, or MOSFET gates |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistor R1 | 4.7 kΩ pull-up eliminates need for external base resistor, reducing BOM count and layout area |
| Guaranteed hFE min | 120 at IC = 50 mA ensures robust saturation margin even with process variation |
| Low VCE(sat) | 0.4 V max at rated current minimizes power dissipation in high-duty-cycle switching |
| Thermal robustness | RthJS = 215 K/W enables operation up to 150 °C junction temperature with standard PCB copper |
| ESD tolerance | HBM rating > 2 kV (per Infineon qualification) supports handling in non-ESD-controlled environments |
Applications
| Automotive Interior Lighting Control | Industrial PLC Output Stage |
|---|---|
Use Scenario: Driving 12 V LED strings in door modules and ambient lighting panels. IC Role / Device Role / Timing Role: High-side switch controlled by 3.3 V CAN microcontroller GPIO. Use Value: Built-in R1 eliminates discrete resistor placement; VCE(sat) ≤ 0.4 V limits heat rise in sealed enclosures. | Use Scenario: Isolating 24 V DC outputs from programmable logic controller backplane. IC Role / Device Role / Timing Role: Level-shifting interface between low-voltage FPGA and industrial solenoid drivers. Use Value: hFE ≥ 120 guarantees full saturation with 2 mA FPGA output current, reducing gate drive complexity. |
| Consumer Appliance Display Backlight | Medical Instrument Status Indication |
Use Scenario: PWM-dimming of white LED arrays in smart oven control panels. IC Role / Device Role / Timing Role: Constant-current switch modulated at 1–5 kHz by MCU timer output. Use Value: fT = 150 MHz ensures clean edge transitions and minimal overshoot at 5 kHz switching. | Use Scenario: Fault-tolerant LED status indicators in battery-powered diagnostic handhelds. IC Role / Device Role / Timing Role: Low-power indicator driver activated by microcontroller wake-up interrupt. Use Value: ICBO ≤ 100 nA prevents false triggering during deep-sleep modes with floating inputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCR570E6327 | Same SOT23 package; R1 = 10 kΩ (vs. 4.7 kΩ); hFE min = 100 at IC = 50 mA | Higher input impedance suits 5 V CMOS logic; lower hFE requires stronger base drive | Select when driving from higher-voltage logic or when reduced base current is critical |
| NSVD120DP033T1G | PNP digital transistor in SOT416; R1 = 4.7 kΩ; VCEO = 50 V; but IC = 200 mA (vs. 500 mA) | Lower current rating restricts use to sub-100 mA loads; smaller footprint increases thermal density | Choose only for space-constrained designs with ≤100 mA load requirements |
Compared with BCR 569 E6327, BCR570E6327 trades base resistor value for higher input impedance, while NSVD120DP033T1G sacrifices current capacity for size reduction - neither matches its combination of 500 mA rating, 4.7 kΩ R1, and 630 hFE in SOT23.

FAQ
Is BCR 569 E6327 suitable for 24 V automotive systems?
Yes - its VCEO = 50 V and VCBO = 50 V exceed typical 24 V system transients (ISO 7637-2 Pulse 1/2a). Tested to operate continuously at Tj = 150 °C, it withstands under-hood thermal stress when mounted on 1 oz copper with ≥1 cm² thermal pad.
Can BCR 569 E6327 replace a standard PNP transistor like BC807?
No - unlike BC807, BCR 569 E6327 integrates R1 = 4.7 kΩ and lacks separate base connection. It functions as a 3-terminal digital switch, not a general-purpose amplifier. Direct replacement requires redesigning base bias network and verifying hFE stability at target IC.
What is the maximum safe switching frequency for PWM dimming?
Based on fT = 150 MHz and measured VCE(sat) recovery time < 100 ns, BCR 569 E6327 supports clean PWM operation up to 100 kHz. For 1–5 kHz LED dimming, it delivers <1% duty-cycle error due to negligible storage time (ts < 20 ns per datasheet Fig. 3).
Does BCR 569 E6327 require an external flyback diode when driving inductive loads?
Yes - although VCEO = 50 V provides margin, inductive kickback from relays or solenoids can exceed this rating. A 1N4148 or BAT54S must be placed cathode-to-collector, anode-to-emitter to clamp reverse voltage and prevent avalanche failure during turn-off.
