Product details

Overview

BC848BWH6327XTSA1 from Infineon Technologies is an NPN silicon general-purpose bipolar junction transistor (BJT) designed for audio-frequency input stages and driver applications. It features a DC current gain (h_FE) of 200–450 at I_C = 2 mA, V_CE = 5 V; V_CEO = 30 V; V_CE(sat) ≤ 250 mV at I_C = 10 mA, I_B = 0.5 mA; and low noise (F = 1.2–4 dB) in the 1 kHz band - used in automotive sensor signal conditioning and industrial analog front-ends.

For engineers reviewing the BC848BWH6327XTSA1 datasheet, BC848BWH6327XTSA1 pinout, BC848BWH6327XTSA1 application, or BC848BWH6327XTSA1 equivalent, key selection criteria include verified h_FE group B performance, AEC-Q101 qualification for automotive use, SOT323 package thermal resistance (R_thJS ≤ 105 K/W), and complementary PNP pairing with BC857B/BC858B.

Technical Context

This transistor operates as a linear amplifying or switching element in low-voltage, medium-current analog signal paths. Its h_FE grouping (B = 200–450) ensures predictable gain stability across production lots, while the 30 V V_CEO rating targets 24 V automotive and 24/36 V industrial control rails.

The device's low V_CE(sat) (≤250 mV) and low-noise design (1.2 dB typ. @ 1 kHz) support high-fidelity small-signal amplification in sensor interfaces and pre-driver stages where base drive efficiency and SNR preservation are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	30 V - supports operation in 24 V nominal automotive and industrial supply domains without breakdown risk.
h_FE (I_C = 2 mA)	200–450 - enables stable small-signal amplification with minimal gain variation across temperature and unit-to-unit spread.
V_CE(sat)	≤250 mV @ I_C/I_B = 10 mA/0.5 mA - reduces conduction loss and self-heating in switching or saturated driver configurations.
Noise Figure	1.2–4 dB @ 1 kHz - meets requirements for low-noise preamplification of resistive sensor outputs (e.g., thermistors, strain gauges).
f_T	250 MHz typ. - provides sufficient bandwidth for audio-frequency amplification and fast digital switching up to ~50 MHz.
R_thJS	≤105 K/W - enables reliable power dissipation up to 250 mW at T_S ≤ 124 °C in SOT323 footprint.

Pinout & Package

BC848BWH6327XTSA1 is housed in a RoHS-compliant SOT323 (SC-70) plastic surface-mount package with standard three-terminal configuration and gull-wing leads.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Provides low-impedance return path; polarity defines NPN topology and biasing direction.
2 (Base)	Control input	Accepts current-limited drive to modulate collector-emitter conduction; requires external series resistor for stable bias.
3 (Collector)	Current source terminal	Delivers amplified output current; connects to load or next stage; voltage swing limited by V_CEO = 30 V.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive electronics per stress test requirements including HTOL, TC, HAST - suitable for under-hood and body-control modules.
Low V_CE(sat)	≤250 mV ensures <1% voltage drop across transistor in saturated switch mode, improving power efficiency in discrete driver circuits.
Group B h_FE	200–450 range allows consistent DC bias point setting without individual gain binning in production assemblies.
Low-noise operation	1.2 dB typical noise figure at 1 kHz enables direct coupling to precision analog sensors without added op-amp stages.

Applications

IC Role / Device Role / Timing Role: High-gain switch enabling fast MOSFET turn-on with minimal MCU GPIO current demand.

Use Value: h_FE ≥200 at I_C = 10 mA reduces required base drive to <50 µA, easing microcontroller GPIO loading.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC848BW	Same die, identical h_FE group B, but non-AEC-Q101 qualified and marked without 'H6327XTSA1' traceability code.	Not approved for automotive safety-critical or AEC-regulated systems; acceptable for industrial/commercial designs.	Select when AEC-Q101 is not required and cost sensitivity outweighs traceability needs.
MMBT3904LT1G	h_FE = 100–300 (lower max), V_CEO = 40 V (higher), R_thJS = 200 K/W (worse thermal performance in SOT23).	Higher voltage margin but lower gain consistency and higher thermal resistance limits continuous current capability.	Prefer for 36 V systems needing extra headroom; avoid where h_FE > 400 or low-noise <2 dB is mandatory.

Compared with BC848BW and MMBT3904LT1G, BC848BWH6327XTSA1 uniquely combines AEC-Q101 qualification, h_FE up to 450, and optimized thermal resistance in SOT323 - making it the only choice for automotive-grade, low-noise, high-gain discrete amplification where traceability and reliability are enforced.

FAQ

Is BC848BWH6327XTSA1 pin-compatible with BC847B or BC849B?

No - BC848BWH6327XTSA1 uses SOT323 packaging, while BC847B and BC849B are offered in SOT23 and SOT23 variants respectively. Pin numbering matches (E-B-C), but physical dimensions, thermal resistance (R_thJS = 105 K/W vs. 240 K/W), and solder pad layout differ. PCB redesign is required for substitution.

What does the 'H6327XTSA1' suffix indicate?

The 'H6327XTSA1' suffix denotes Infineon's standardized tape-and-reel packaging: H = halogen-free, 6327 = reel size (7" reel, 3000 pcs), X = special marking, TSA1 = lead-free, RoHS-compliant, AEC-Q101-qualified lot traceability code per JEDEC J-STD-020.

Can BC848BWH6327XTSA1 replace BC848BL3 in existing designs?

Yes, electrically - both share identical h_FE group B, V_CEO = 30 V, and SOT323 package. However, BC848BL3 has R_thJS ≤ 60 K/W (vs. 105 K/W), meaning BC848BWH6327XTSA1 dissipates heat less efficiently. Derate power by ~40% if operating near 250 mW limits.

Does this transistor support linear operation at I_C = 100 mA?

Yes, but only in pulsed mode: I_C = 100 mA is permitted for t_p ≤ 10 ms (duty cycle ≤ 2%). Continuous operation is limited to I_C = 100 mA only if T_S ≤ 124 °C and P_tot ≤ 250 mW - verify board-level thermal design using R_thJS ≤ 105 K/W and ambient derating curves.
