Product details
Overview
BC848CE6433HTMA1 from Nexperia 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 (hFE) of 420–800 at IC = 2 mA, VCE = 5 V; VCEO = 30 V; VCE(sat) ≤ 250 mV at IC = 10 mA, IB = 0.5 mA; and low noise (F = 1.2–4 dB) in the 1 kHz band - enabling high-fidelity signal amplification in compact analog front-ends.
For engineers reviewing the BC848CE6433HTMA1 datasheet, BC848CE6433HTMA1 pinout, BC848CE6433HTMA1 application, or BC848CE6433HTMA1 equivalent, key selection criteria include its AEC-Q101 qualification for automotive use, SOT23 package compatibility with high-density PCB layouts, hFE group C performance consistency, and RoHS-compliant Pb-free construction.
Technical Context
This transistor operates as a linear amplifying device in Class-A or Class-AB configurations, with verified hFE grouping (C) ensuring tight current gain distribution across production lots. Its low VCE(sat) and high fT (250 MHz typ.) support efficient small-signal switching and broadband AF amplification up to 15 kHz.
The device's thermal resistance RthJS ≤ 240 K/W (SOT23) and Tj rating of 150 °C enable reliable operation in thermally constrained environments. Complementary PNP types (e.g., BC858C) are available for push-pull designs, and its ESD robustness meets HBM ≥ 2 kV per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 30 V - maximum collector-emitter voltage before breakdown under open-base conditions; defines safe operating voltage headroom in low-voltage amplifier rails. |
| hFE (IC = 2 mA) | 420–800 - guaranteed DC current gain range for Group C devices; enables predictable biasing and stable gain in discrete amplifier stages. |
| VCE(sat) | ≤ 250 mV @ IC = 10 mA, IB = 0.5 mA - low saturation voltage reduces power loss and improves efficiency in switching and driver circuits. |
| fT | 250 MHz (typ.) - transition frequency confirms usable bandwidth beyond audio spectrum, supporting fast edge response in pulse applications. |
| Noise Figure | 1.2–4 dB @ IC = 200 µA, f = 1 kHz - quantified low-noise performance critical for microphone preamps and sensor interface amplifiers. |
| Ptot | 330 mW @ TS ≤ 71 °C - total power dissipation limit in SOT23 package; determines thermal derating requirements on PCB copper area. |
Pinout & Package
BC848CE6433HTMA1 is housed in a standard SOT23 plastic surface-mount package (3-pin, 1.3 mm × 2.9 mm × 1.0 mm), with lead finish NiPdAu and RoHS-compliant Pb-free plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Provides low-impedance return path; connects to ground or emitter resistor in common-emitter configuration. |
| 2 (Base) | Control input | Accepts bias current to modulate collector current; requires series resistor to limit drive and ensure stable hFE-based operation. |
| 3 (Collector) | Current source terminal | Delivers amplified output current; connects to load or next stage; must remain within VCEO/VCBO limits. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, temperature cycling, and ESD. |
| Low VCE(sat) | ≤ 250 mV ensures minimal voltage drop and heat generation when used as a saturated switch or active load. |
| Group C hFE | Guaranteed 420–800 gain range simplifies circuit design by eliminating need for manual binning or feedback trimming. |
| Low-noise AF performance | 1.2–4 dB noise figure at 1 kHz supports high-SNR signal conditioning in audio and sensor front-ends. |
Applications
| Audio Pre-amplifier Stage | Automotive Door Module Driver |
|---|---|
Use Scenario: Amplifying weak signals from electret microphones or piezoelectric sensors in portable voice recorders. IC Role / Device Role / Timing Role: Discrete NPN BJT configured in common-emitter topology for voltage gain and impedance matching. Use Value: Low 1.2 dB noise figure and stable hFE group C ensure consistent SNR and gain accuracy across production units. | Use Scenario: Driving LED indicators and small relays in vehicle door control modules subject to temperature cycling and vibration. IC Role / Device Role / Timing Role: General-purpose switching transistor controlling 20–50 mA loads with logic-level base drive. Use Value: AEC-Q101 qualification and VCEO = 30 V provide reliability margin against battery transients and long-term thermal stress. |
| Industrial Sensor Interface | Consumer Appliance Control Board |
Use Scenario: Buffering and level-shifting analog outputs from temperature or pressure sensors in HVAC controllers. IC Role / Device Role / Timing Role: Emitter-follower buffer providing high input impedance and low output impedance for signal integrity. Use Value: High hFE (≥420) minimizes base current loading on sensitive sensor outputs while maintaining linearity. | Use Scenario: Controlling buzzer drivers and display segment transistors in microwave ovens and washing machines. IC Role / Device Role / Timing Role: Low-cost, high-reliability switching element replacing mechanical relays in cost-sensitive consumer products. Use Value: SOT23 footprint enables compact board layout, and 330 mW Ptot supports continuous 100 mA operation with minimal heatsinking. |
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 |
|---|---|---|---|
| BC848CW | Same die, identical hFE group C, but marked "CW" instead of "CE6433HTMA1"; same SOT23 package and electrical specs. | No functional difference; CW is standard Nexperia marking variant for same specification grade. | Select BC848CW if standard marking suffices and traceability to HTMA1 batch is not required. |
| MMBT3904LT1G | hFE = 100–300 (lower gain range); VCEO = 40 V; fT = 300 MHz; different gain binning and thermal resistance (RthJS ≈ 300 K/W). | Better high-frequency response but less suitable for low-noise, high-gain AF stages due to wider hFE spread and higher noise. | Choose MMBT3904LT1G only when higher VCEO or fT is prioritized over gain consistency and noise performance. |
Compared with BC848CW and MMBT3904LT1G, BC848CE6433HTMA1 offers superior gain uniformity (hFE 420–800), lower noise (1.2 dB min), and AEC-Q101 validation - making it optimal for automotive and precision analog applications where parameter stability is critical.

FAQ
Is BC848CE6433HTMA1 pin-compatible with BC847C or BC849C?
Yes - all three share identical SOT23 pinout (Emitter-Base-Collector on pins 1-2-3) and mechanical footprint. However, BC848C has VCEO = 30 V (vs. 45 V for BC847C and 30 V for BC849C), so substitution requires verification of voltage headroom in the target circuit.
What does the "E6433HTMA1" suffix indicate in the part number?
The "E6433HTMA1" suffix denotes Nexperia's internal manufacturing code: "E6433" identifies the wafer lot and process revision, "HT" indicates high-temperature testing, "MA1" specifies tape-and-reel packaging per EIA-481 standard with 3,000 units per reel.
Can BC848CE6433HTMA1 be used in linear regulator pass-transistor roles?
No - it is not rated for continuous high-current linear operation. Its Ptot = 330 mW and RthJS ≤ 240 K/W limit safe dissipation to ~100 mA at modest VCE; dedicated power transistors or LDO ICs are recommended for regulator applications.
Does this transistor support hot-swap or in-circuit replacement?
Not inherently - BC848CE6433HTMA1 lacks integrated protection features like current limiting or thermal shutdown. Safe hot-swap requires external current-limiting resistors, soft-start circuitry, and board-level ESD safeguards per IEC 61000-4-2 Level 3.
