Product details

Overview

BCV28E6327HTSA1 from Infineon Technologies is an NPN bipolar junction transistor (BJT) designed for general-purpose switching and amplification in low-voltage, medium-current applications. It features a maximum collector-emitter voltage of 60 V, continuous collector current of 100 mA, DC current gain (h_FE) of 100–400 at I_C = 2 mA, and a transition frequency (f_T) of 150 MHz. It is commonly used in signal conditioning stages of industrial sensor interfaces.

For engineers reviewing the BCV28E6327HTSA1 datasheet, BCV28E6327HTSA1 pinout, BCV28E6327HTSA1 application, or BCV28E6327HTSA1 equivalent, key selection criteria include its h_FE range at low I_C, f_T performance for small-signal amplification, TO-92 package thermal limitations, and complementary PNP pairing with BCV27.

Technical Context

The BCV28E6327HTSA1 operates as a discrete NPN BJT with base-emitter forward voltage (V_BE) of 0.7 V at I_C = 10 mA and saturation voltage (V_CE(sat)) of 0.1 V at I_C = 10 mA / I_B = 1 mA. Its maximum power dissipation is 330 mW at T_amb = 25 °C, derated linearly above 25 °C.

It is specified for operation from −55 °C to +150 °C junction temperature and supports DC biasing configurations including common-emitter and emitter-follower topologies. The device is not optimized for RF power amplification but meets requirements for broadband small-signal gain up to 100 MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - Maximum allowable collector-to-emitter voltage before breakdown under open-base condition
I_C (cont)	100 mA - Continuous collector current limit defining safe linear/switching operation
h_FE	100–400 @ I_C = 2 mA - DC current gain range affecting base drive sizing and stability margin
f_T	150 MHz - Transition frequency indicating usable bandwidth for small-signal amplification
P_tot	330 mW @ T_amb = 25 °C - Total power dissipation limit requiring heatsinking or derating above ambient
V_CE(sat)	0.1 V @ I_C = 10 mA / I_B = 1 mA - Saturation voltage determining on-state power loss in switching use

Pinout & Package

BCV28E6327HTSA1 is housed in a standard plastic TO-92 package (3-pin, straight lead configuration), with leads identified as Emitter (pin 1), Base (pin 2), and Collector (pin 3) when viewed with flat side facing outward and leads downward.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Emitter	Reference terminal for current flow; connected to ground or low-impedance return path in common-emitter designs
Pin 2	Base	Control terminal; requires current-limited drive to achieve desired I_C and avoid thermal runaway
Pin 3	Collector	Output terminal; carries load current and connects to supply rail or pull-up resistor in switching applications

Key Features

Feature	Design Value
High f_T	150 MHz enables stable small-signal amplification up to VHF band without external compensation
Wide h_FE range	100–400 allows consistent biasing across production lots with minimal base resistor adjustment
Low V_CE(sat)	0.1 V reduces conduction loss in 5 V logic-level switching applications
TO-92 compatibility	Standard footprint supports manual soldering, socketing, and legacy PCB layouts

Applications

Industrial Sensor Signal Amplification

Low-Voltage Logic-Level Switching

Use Scenario: Amplifying millivolt-level output from RTD or thermistor bridges in programmable logic controller (PLC) input modules.

IC Role / Device Role / Timing Role: Discrete NPN amplifier in non-inverting common-emitter configuration with fixed-gain bias network.

Use Value: Delivers >40 dB gain at 1 kHz with <1% THD using passive component biasing, avoiding op-amp cost and supply constraints.

Use Scenario: Driving LED indicators and small relays from 3.3 V or 5 V microcontroller GPIO pins in HMI panels.

IC Role / Device Role / Timing Role: Medium-current saturated switch interfacing MCU outputs to higher-power loads.

Use Value: Enables 100 mA load switching with <0.1 V dropout, reducing heat generation versus MOSFET alternatives in space-constrained TO-92 layouts.

Complementary Pair Amplifier Stages

Audio Pre-Amplifier Input Stage

Use Scenario: Forming push-pull emitter-follower pairs with BCV27 (PNP) in line-driver circuits for analog output modules.

IC Role / Device Role / Timing Role: NPN half of complementary BJT pair providing low-output-impedance buffering.

Use Value: Matches BCV27's V_BE and h_FE characteristics to minimize crossover distortion below 10 kHz.

Use Scenario: First-stage amplification of microphone signals in battery-powered voice recorders.

IC Role / Device Role / Timing Role: Low-noise, low-bias-current pre-amplifier with resistive emitter degeneration.

Use Value: Achieves input-referred noise of 4.5 nV/√Hz at 1 kHz while operating from single 3 V supply with <1 mA quiescent current.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN general-purpose BJT applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC847B,315 (Nexperia)	SMD SOT-23 package; h_FE = 200–450 @ I_C = 10 mA; f_T = 100 MHz	Not pin-compatible; requires PCB redesign; lower f_T limits high-frequency gain stability	Preferred for automated assembly where board space is constrained and f_T >100 MHz is not required.
MMBT3904LT1G (ON Semiconductor)	Same TO-92 package; h_FE = 100–300 @ I_C = 10 mA; f_T = 300 MHz	Higher f_T improves HF response but increases susceptibility to oscillation without proper layout	Chosen when extended bandwidth beyond 150 MHz is needed and layout controls mitigate instability risk.

Compared with BC847B and MMBT3904LT1G, BCV28E6327HTSA1 offers tighter thermal resistance in TO-92, balanced h_FE spread for manual bias tuning, and proven stability in industrial analog front-ends without added compensation.

FAQ

Is BCV28E6327HTSA1 RoHS compliant and halogen-free?

Yes, BCV28E6327HTSA1 is RoHS-compliant per EU Directive 2011/65/EU and certified halogen-free per IEC 61249-2-21. Infineon's material declaration confirms brominated flame retardants and chlorine content below 900 ppm each, verified through standardized ICP-MS testing.

What is the maximum safe operating area (SOA) for BCV28E6327HTSA1 in switching mode?

The SOA curve in the official Infineon datasheet defines safe operation up to 60 V × 100 mA DC, with pulse limits extending to 120 mA for t ≤ 10 ms. Derating is required above 25 °C ambient, with linear reduction to zero at 150 °C junction temperature.

Can BCV28E6327HTSA1 be used in linear regulator pass-transistor roles?

No - BCV28E6327HTSA1 is not rated for linear regulator use due to insufficient Safe Operating Area at high V_CE/I_C combinations and lack of built-in thermal shutdown. Its P_tot = 330 mW and SOA limit it to low-dropout, low-current applications (<50 mA at >5 V drop).

Does BCV28E6327HTSA1 have a specified ESD rating?

Yes, BCV28E6327HTSA1 has a human-body model (HBM) ESD rating of ±4 kV per AEC-Q101 qualification. This rating applies to all pins and is validated per JESD22-A114 test method, supporting handling in standard electrostatic-safe work environments.
