Product details

Overview

BCV28H6327XTSA1 from Infineon Technologies is a PNP silicon Darlington transistor designed for general audio-frequency amplification and low-speed switching in automotive and industrial control circuits. It delivers 500 mA collector current, 30 V V_CEO, minimum DC current gain (h_FE) of 4000 at 10 µA I_C, and operates up to 150 °C junction temperature. Its SOT-89 package supports thermal dissipation up to 1 W at T_S ≤ 130 °C.

For engineers reviewing the BCV28H6327XTSA1 datasheet, BCV28H6327XTSA1 pinout, BCV28H6327XTSA1 application, or BCV28H6327XTSA1 equivalent, key selection criteria include Darlington saturation voltage (V_CEsat ≤ 1 V at I_C = 100 mA), high h_FE stability across I_C = 10 µA–500 mA, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

The BCV28H6327XTSA1 integrates two cascaded PNP transistors in a single SOT-89 package to achieve high current gain with minimal base drive. Its Darlington configuration enables direct interface with microcontroller GPIOs driving moderate loads such as relays or small solenoids without external amplification stages.

It features complementary NPN counterpart BCV29 and shares identical SOT-89 footprint and thermal resistance (R_thJS ≤ 20 K/W). Electrical characteristics are specified over −55 °C to 150 °C, supporting operation in under-hood automotive environments and industrial motor-control feedback paths.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	30 V - Maximum safe collector-emitter voltage before breakdown in open-base condition
I_C	500 mA - Continuous collector current rating enabling direct relay coil drive
h_FE	4000–20000 - High DC current gain ensures <100 µA base current suffices for 500 mA output
V_CEsat	≤1 V @ I_C=100 mA, I_B=0.1 mA - Low saturation voltage minimizes power loss in switching mode
R_thJS	≤20 K/W - Thermal resistance from junction to soldering point supports 1 W dissipation at T_S ≤ 130 °C
f_T	200 MHz - Transition frequency confirms suitability for AF amplification up to ~10 kHz with margin
AEC-Q101	Qualified - Meets stress-test requirements for automotive electronic components

Pinout & Package

SOT-89 package: 3-pin surface-mount plastic case with exposed thermal pad on underside; pin 1 = Base, pin 2 = Collector, pin 3 = Emitter; standardized footprint per Infineon outline drawing (Rev. 2009-11-16).

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Control input	Receives low-current signal to enable high-current conduction between C and E
2 (Collector)	High-side load connection	Connected to positive supply rail when used in low-side switch configuration
3 (Emitter)	Current return path	Typically tied to ground; provides reference for V_BE bias and sets emitter-follower output

Key Features

Feature	Design Value
High h_FE at low I_C	Min. 4000 at I_C = 10 µA - Enables reliable turn-on with weak MCU outputs
Low V_CEsat	≤1 V at I_C = 100 mA - Reduces conduction loss in 12 V relay drivers by >30% vs. standard PNP
AEC-Q101 qualification	Validated for automotive ambient temperatures (−55 °C to 150 °C) - Eliminates need for additional qualification testing
Complementary pairing	Matched with BCV29 (NPN) - Simplifies push-pull output stage design in linear regulators and H-bridge pre-drivers

Applications

Automotive Door Lock Actuator Control

Industrial PLC Output Stage

Use Scenario: Driving 12 V, 300 mA solenoid lock actuators in vehicle door modules.

IC Role / Device Role / Timing Role: PNP Darlington switch providing high-gain current amplification from 3.3 V MCU GPIO.

Use Value: V_CEsat ≤ 1 V limits power dissipation to <300 mW, avoiding heatsink requirement in space-constrained modules.

Use Scenario: Switching 24 V DC loads (valves, indicators) in programmable logic controller output cards.

IC Role / Device Role / Timing Role: Final-stage current amplifier interfacing field-programmable gate array (FPGA) I/O banks to industrial loads.

Use Value: h_FE ≥ 4000 allows full 500 mA drive with <125 µA FPGA output current, preserving I/O drive strength for other functions.

Audio Frequency Pre-amplifier

Temperature Sensor Bias Circuit

Use Scenario: Low-noise, high-input-impedance pre-amplifier stage for electret microphone signals in infotainment systems.

IC Role / Device Role / Timing Role: Common-collector (emitter-follower) buffer isolating sensitive analog front-end from downstream ADC input capacitance.

Use Value: f_T = 200 MHz ensures flat gain response up to 20 kHz with <0.1 dB deviation, meeting automotive audio fidelity specs.

Use Scenario: Constant-current bias source for platinum RTD (PT100) sensors in HVAC control units.

IC Role / Device Role / Timing Role: Precision current source configured with external resistor to deliver stable 1 mA excitation current.

Use Value: h_FE stability over −40 °C to 125 °C maintains <±0.5% current error across operating range, eliminating calibration drift.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BCV29H6327XTSA1	NPN complement; same SOT-89 package, 30 V V_CEO, 500 mA I_C, but opposite polarity	Required where load connects to V_CC (high-side switching) instead of ground	Select when circuit topology demands NPN Darlington behavior or push-pull symmetry
ZTX951	Higher V_CEO (60 V), lower h_FE (min. 1000), TO-92 package - no AEC-Q101 qualification	Suitable for non-automotive 24 V industrial controls where qualification is not mandated	Choose only if higher voltage rating is critical and automotive compliance is unnecessary

Compared with BCV29H6327XTSA1, the BCV28H6327XTSA1 enables grounded-load switching with minimal base drive; versus ZTX951, it trades voltage headroom for guaranteed automotive qualification and superior current gain at low drive levels.

FAQ

What is the maximum allowable continuous collector current for BCV28H6327XTSA1?

The BCV28H6327XTSA1 is rated for 500 mA continuous collector current (I_C) at case temperature T_S ≤ 130 °C. Derating is required above this temperature per the P_tot vs. T_S curve in Infineon's datasheet (EHP00310), with zero dissipation at 150 °C junction temperature.

Does BCV28H6327XTSA1 require a base resistor, and how is its value calculated?

Yes - a series base resistor is mandatory to limit base current. For I_C = 500 mA and minimum h_FE = 4000, required I_B ≥ 125 µA. With V_BEsat ≈ 1.5 V and 3.3 V MCU output, R_B = (3.3 V − 1.5 V)/125 µA = 14.4 kΩ; 12 kΩ is recommended for margin.

Can BCV28H6327XTSA1 be used in linear regulator pass transistor applications?

No - its Darlington structure introduces high V_BEsat (~1.5 V) and poor SOA (Safe Operating Area) under linear bias. It is optimized for saturated switching, not analog regulation. Use dedicated LDOs or single-transistor pass elements like BD139 for linear applications.

Is BCV28H6327XTSA1 compatible with lead-free reflow profiles?

Yes - it is RoHS-compliant and qualified for standard Pb-free reflow per JEDEC J-STD-020. Peak temperature must not exceed 260 °C for ≤ 30 seconds, with ramp rates ≤ 3 °C/s, matching IPC-A-610 Class 3 requirements for automotive assemblies.
