Product details

Overview

BCR169E6327HTSA1 from Infineon Technologies is a PNP silicon digital transistor with integrated bias resistor (R1 = 4.7 kΩ), designed for switching, inverting, interfacing, and driver circuits in automotive and industrial control systems. 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 AEC-Q101 qualification.

For engineers reviewing the BCR169E6327HTSA1 datasheet, BCR169E6327HTSA1 pinout, BCR169E6327HTSA1 application, or BCR169E6327HTSA1 equivalent, key selection criteria include built-in R1 tolerance (3.2–6.2 kΩ), thermal resistance R_thJS ≤ 240 K/W, SOT23 package compatibility, and guaranteed operation up to T_j = 150 °C.

Technical Context

This digital transistor integrates a PNP bipolar junction transistor with a monolithic 4.7 kΩ base bias resistor (R1), eliminating external component count in simple on/off control paths. Its common-emitter configuration supports direct logic-level drive from microcontrollers or gate drivers without additional base resistors.

The device operates across –65 °C to +150 °C storage and junction temperature ranges, with specified V_i(off) (0.4–0.8 V) and V_i(on) (0.5–1.1 V) enabling robust noise margin in 3.3 V/5 V digital systems. Thermal derating curves confirm stable 200 mW dissipation at T_S ≤ 102 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with safety margin.
I_C	100 mA - Continuous collector current rating; suitable for driving LEDs, small relays, or logic-level MOSFET gates.
V_CE(sat)	≤ 0.3 V @ I_C=10 mA/I_B=0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching mode.
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	4.7 kΩ (3.2–6.2 kΩ) - Integrated base bias resistor eliminates external component; defines input current threshold for logic-driven switching.
f_T	200 MHz - Transition frequency supports fast edge response in pulse-width modulation and digital signal buffering.
T_j max	150 °C - Junction temperature limit validated per AEC-Q101; supports under-hood automotive placement.

Pinout & Package

BCR169E6327HTSA1 is housed in a standard SOT23 plastic surface-mount package (JEDEC TO-236AB), measuring 2.9 mm × 1.3 mm × 1.0 mm, with gull-wing leads and moisture sensitivity level (MSL) 1.

Pin/Terminal	Circuit Role	Design Meaning

3 (C)	Collector	Output node; connects to load (e.g., LED cathode or relay coil); switches high-side loads when active.

Key Features

Feature	Design Value

FAQ

Is BCR169E6327HTSA1 pin-compatible with standard SOT23 NPN transistors?

No. BCR169E6327HTSA1 is a PNP digital transistor with Base (Pin 1), Emitter (Pin 2), and Collector (Pin 3) pinout. Standard SOT23 NPN transistors (e.g., BC847) use Emitter (Pin 1), Base (Pin 2), Collector (Pin 3). Swapping them causes circuit failure due to reversed polarity and internal resistor topology.

What is the maximum allowable continuous current at 85 °C ambient?

At T_A = 85 °C, derated power dissipation is ~130 mW (per thermal curve on page 5). With V_CE(sat) ≤ 0.3 V, maximum continuous I_C ≈ 430 mA is theoretically possible-but absolute I_C rating remains 100 mA per datasheet limits. Exceeding 100 mA violates SOA and voids AEC-Q101 compliance.

Can BCR169E6327HTSA1 be used in linear amplifier configurations?

No. This device is optimized for saturated switching, not linear operation. Its h_FE variation across I_C, lack of linearity data, and unspecified f_T at low currents make it unsuitable for analog amplification. Use dedicated general-purpose PNP transistors (e.g., BC807) for linear gain stages.

Does the built-in R1 resistor support PWM switching at 20 kHz?

Yes. With f_T = 200 MHz and nanosecond-scale switching times confirmed in application note AN077, BCR169E6327HTSA1 reliably handles 20 kHz PWM for LED dimming or fan speed control. Layout must minimize base trace inductance to preserve edge integrity.
