Product details
Overview
BC848W,135 from Nexperia is an NPN general-purpose bipolar junction transistor in SOT323 (SC-70) surface-mount package, rated for 30 V VCEO, 100 mA IC, and DC current gain (hFE) of 110–800 at IC = 2 mA, VCE = 5 V. It serves as a low-voltage switching and small-signal amplification device in space-constrained consumer and industrial PCBs.
For engineers reviewing the BC848W,135 datasheet, BC848W,135 pinout, BC848W,135 application, or BC848W,135 equivalent, this page delivers verified electrical parameters, thermal limits, package dimensions, pin functionality, and direct alternatives - all aligned with Nexperia's Rev. 07 product data sheet dated 17 November 2009.
Technical Context
The BC848W operates as a silicon NPN BJT with base-controlled current amplification, optimized for linear amplification and saturated switching in low-power analog and digital interface circuits. Its hFE spread (110–800) supports both precision biasing and robust on/off control across temperature ranges.
Thermal performance is defined for FR4 PCB mounting (1.6 mm thickness, single-sided copper), with Rth(j-a) = 625 K/W and Ptot = 200 mW at Tamb ≤ 25 °C. Saturation voltage remains ≤250 mV at IC = 10 mA / IB = 0.5 mA, enabling efficient low-drop switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 30 V - Maximum collector-emitter voltage before breakdown; sets safe operating range for 24 V rail interfaces. |
| IC | 100 mA - Continuous collector current limit; suitable for driving LEDs, small relays, or logic-level signal buffering. |
| hFE | 110–800 - DC current gain at VCE = 5 V, IC = 2 mA; enables wide design margin for bias stability across production lots. |
| VCE(sat) | 90–250 mV - Collector-emitter saturation voltage at IC = 10 mA / IB = 0.5 mA; ensures low conduction loss in switch mode. |
| Ptot | 200 mW - Total power dissipation on FR4 PCB; defines thermal derating envelope for ambient temperatures up to +150 °C. |
| Rth(j-a) | 625 K/W - Junction-to-ambient thermal resistance; informs heatsinking requirements for sustained 100 mA operation. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.9 mm × 1.25 mm footprint, 0.95 mm height, 3-terminal configuration with gull-wing leads. Designed for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input node; requires ~0.5 mA drive for full saturation at 10 mA collector load. |
| 2 | Emitter | Reference terminal for bias network; connected to ground or common return path in common-emitter configuration. |
| 3 | Collector | Output current sink node; handles up to 100 mA continuous load with <250 mV drop when properly biased. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SOT323 package | Enables high-density PCB layouts in wearables, IoT sensors, and compact power management modules. |
| Wide hFE range (110–800) | Reduces need for binning in production; accommodates variability in base drive circuit tolerances. |
| Guaranteed VCE(sat) ≤ 250 mV | Minimizes power loss and self-heating during switching, critical for battery-powered applications. |
| JEITA/IEC-compliant limiting values | Ensures reliability under transient overvoltage (30 V VCBO) and thermal stress (Tj ≤ 150 °C). |
Applications
| LED Driver Circuit | Microcontroller GPIO Expander |
|---|---|
|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V microcontroller outputs. IC Role / Device Role / Timing Role: NPN switch configured in common-emitter mode, sinking LED current to ground. Use Value: VCE(sat) ≤ 250 mV ensures >3.05 V forward voltage remains across LED, maintaining brightness consistency. |
Use Scenario: Level-shifting and current boosting for legacy 5 V peripherals interfaced to 3.3 V MCUs. IC Role / Device Role / Timing Role: Digital buffer amplifier translating logic-high signals while sourcing/sinking ≥10 mA. Use Value: hFE ≥ 110 guarantees reliable turn-on with MCU GPIO output current ≤ 0.1 mA. |

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 |
|---|---|---|---|
| BC847W,135 | VCEO = 45 V, hFE = 200–450 (narrower spread), same SOT323 package | Better suited for higher-voltage rails (e.g., 36 V automotive subsystems) where 30 V margin is insufficient | Select when higher breakdown voltage is required without changing layout or thermal design |
| MMBT3904LT1G | VCEO = 40 V, hFE = 100–300, SOT23 package (larger footprint, higher Ptot = 250 mW) | Offers improved thermal performance but requires PCB redesign due to different land pattern and lead pitch | Choose when board space permits larger package and higher continuous current capability is needed |
Compared with BC848W,135, BC847W,135 provides higher voltage headroom at the cost of reduced hFE flexibility, while MMBT3904LT1G trades miniaturization for thermal robustness and requires mechanical redesign.

FAQ
What is the maximum junction temperature for BC848W,135?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in Table 6 of the Nexperia product data sheet Rev. 07. Operation above this temperature risks permanent parametric shift or failure, and thermal design must ensure junction temperature remains within this limit under worst-case ambient and power dissipation conditions.
Is BC848W,135 RoHS compliant and halogen-free?
Yes - BC848W,135 meets RoHS Directive 2011/65/EU and is halogen-free per Nexperia's material declarations. The device uses lead-free terminations and complies with JEDEC JS-001 ESD standards (HBM Class 3B, ≥8 kV), confirmed in official Nexperia compliance documentation.
Can BC848W,135 replace BC848B in existing designs?
No - BC848W uses SOT323 (SC-70) packaging while BC848B uses SOT23. Though electrically similar, their footprints are incompatible: SOT323 has 1.3 mm lead pitch vs. SOT23's 1.9 mm, and overall dimensions differ significantly. Layout redesign is required for substitution.
What is the typical noise figure of BC848W,135 at 1 kHz?
The typical noise figure is 2 dB at VCE = 5 V, IC = 200 μA, RS = 2 kΩ, and bandwidth = 200 Hz, as stated in Table 8 of the datasheet. This makes it suitable for low-noise preamplifier stages in audio and sensor signal conditioning where sub-10 dB NF is acceptable.
