Product details
Overview
BC848CLT3G from onsemi is an NPN general-purpose silicon transistor in SOT-23 package, rated for 30 VCEO, 100 mA continuous collector current, and DC current gain (hFE) of 420–800 at IC = 2.0 mA, VCE = 5.0 V - used in low-voltage switching and amplification circuits such as LED drivers and signal conditioning stages in industrial sensor interfaces.
For engineers reviewing the BC848CLT3G datasheet, pinout, applications, or equivalent options, key selection criteria include its VCEO = 30 V rating, hFE binning (C-grade), SOT-23 footprint compatibility, and AEC-Q101 qualification for automotive-grade reliability assurance.
Technical Context
The BC848CLT3G operates as a discrete NPN bipolar junction transistor with fixed emitter-base and collector-base junction structures optimized for linear amplification and saturated switching. Its hFE range (420–800) enables stable biasing across temperature (−55°C to +150°C) without external feedback networks in low-power analog stages.
Designed for surface-mount assembly on FR-5 or alumina substrates, it delivers 225 mW total dissipation at TA = 25°C with thermal resistance RJA = 556°C/W (FR-5) or 417°C/W (alumina), supporting operation in compact, thermally constrained PCB layouts typical in portable instrumentation and automotive body control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 30 V - maximum allowable collector-emitter voltage before breakdown; defines safe operating voltage headroom in 24 V rail switching applications. |
| IC (continuous) | 100 mA - maximum DC collector current; supports driving small relays, LEDs, or logic-level interface loads without heatsinking. |
| hFE (min–max) | 420–800 at IC = 2.0 mA, VCE = 5.0 V - high and tightly binned DC gain enables predictable base drive sizing and stable amplifier bias points. |
| VCE(sat) | 0.25 V max at IC = 10 mA, IB = 0.5 mA - low saturation voltage minimizes power loss and self-heating during switching duty cycles. |
| fT | 100 MHz - unity-gain bandwidth supports small-signal amplification up to RF front-end stages in sub-100 MHz sensor transceivers. |
| RJA (FR-5) | 556°C/W - thermal resistance determines junction temperature rise under ambient conditions; critical for lifetime estimation in sealed enclosures. |
Pinout & Package
SOT-23 (TO-236) package: 2.90 mm × 1.30 mm × 1.00 mm body, 1.90 mm lead pitch, JEDEC-compliant footprint for automated placement and reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input node; requires series resistor to limit IB and ensure saturation or linear operation per hFE and load. |
| 2 | Emitter | Common reference terminal; connected to ground or low-side return path; carries full IC + IB current in standard configuration. |
| 3 | Collector | Output node sourcing current to load; placed on high-side of load in common-emitter switch topology; voltage swing limited by VCEO. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics use with PPAP capability; supports deployment in body control units and lighting modules without additional qualification. |
| Pb-free, RoHS compliant | Meets EU RoHS Directive 2011/65/EU and halogen-free/BFR-free requirements; enables compliance in consumer, industrial, and medical end equipment. |
| ESD robustness | HBM > 4000 V, MM > 400 V - reduces risk of field failure during handling and board assembly in unshielded environments. |
| Moisture sensitivity level 1 | No floor life limitation; can be stored indefinitely at ≤30°C/85% RH and assembled without baking prior to reflow. |
Applications
| LED Driver Circuit | Industrial Sensor Interface |
|---|---|

IC Role / Device Role / Timing Role: High-side switch (with PNP driver stage) or low-side enable switch for USB VBUS path; operated in linear or saturated region. Use Value: VCEO = 30 V provides 6× margin over 5 V rail, ensuring immunity to transient overshoots during hot-plug events. |
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 |
|---|---|---|---|
| BC848BLT3G | Lower hFE range (200–450); same VCEO, IC, package, and thermal specs. | Suitable where gain tolerance is relaxed (e.g., digital switching only), but not for precision analog amplification requiring ≥420 hFE. | Select BC848BLT3G when cost optimization is prioritized and circuit gain stability is less critical. |
| MMBT3904LT3G | Same SOT-23 package; VCEO = 40 V, hFE = 100–300 (standard grade), fT = 300 MHz. | Better high-frequency response but lower gain consistency; not AEC-Q101 qualified. | Choose MMBT3904LT3G for non-automotive RF-coupled preamps where higher fT outweighs gain and qualification needs. |
Compared with BC848BLT3G and MMBT3904LT3G, the BC848CLT3G uniquely combines automotive qualification, highest hFE binning, and 30 V rating - making it optimal for space-constrained, gain-sensitive, and reliability-critical switching or amplification tasks in harsh environments.

FAQ
What is the maximum collector-emitter voltage rating for BC848CLT3G?
The BC848CLT3G has a maximum collector-emitter voltage (VCEO) rating of 30 V DC. This value is specified under test condition IC = 10 mA and defines the absolute upper limit before avalanche breakdown occurs. Exceeding this voltage risks irreversible device failure, especially under transient conditions - design margins should maintain VCE ≤ 24 V in 24 V system applications. The BC848CLT3G datasheet confirms this rating on page 1 of the June 2024 Rev. 20 document.
Is BC848CLT3G suitable for automotive applications?
Yes, BC848CLT3G is AEC-Q101 qualified and PPAP capable, meeting stress-test requirements for temperature cycling, humidity, mechanical shock, and ESD in automotive environments. It is explicitly listed in onsemi's ordering table with no "DISCONTINUED" flag and supports operation from −55°C to +150°C junction temperature. Its qualification makes BC848CLT3G appropriate for body control modules, lighting systems, and sensor interfaces in passenger vehicles - confirmed in the Features section of the BC846ALT1G Series datasheet.
What is the DC current gain (hFE) range for BC848CLT3G?
The BC848CLT3G exhibits a DC current gain (hFE) range of 420 to 800 when tested at IC = 2.0 mA and VCE = 5.0 V, per the Electrical Characteristics table on page 2 of the datasheet. This C-grade binning provides tighter gain distribution than A- or B-grade variants, enabling more predictable base resistor selection in amplifier and switch designs. The BC848CLT3G's hFE remains stable across −55°C to +125°C ambient, as shown in Figures 28–29.
Does BC848CLT3G have Pb-free and RoHS compliance?
Yes, BC848CLT3G is Pb-free, halogen-free/BFR-free, and fully RoHS compliant per EU Directive 2011/65/EU. The "G" suffix in the part number denotes Pb-free packaging, and the datasheet states compliance explicitly in the Features section on page 1. This ensures BC848CLT3G meets environmental regulations for sale and use in the EU, China, and other regulated markets - verified in the June 2024 Rev. 20 revision of the BC846ALT1G Series datasheet.
What is the thermal resistance (RJA) of BC848CLT3G on FR-5 board?
The BC848CLT3G has a junction-to-ambient thermal resistance (RJA) of 556°C/W when mounted on a standard FR-5 PCB (1.0″ × 0.75″ × 0.062″) at TA = 25°C, as specified in the Thermal Characteristics table on page 1. This value assumes no copper pour or thermal vias; adding 1 in² of 2-oz copper on the collector pad reduces RJA significantly. The BC848CLT3G's 225 mW power dissipation limit at 25°C derives directly from this RJA, and derating is required above ambient - confirmed in Note 1 of the datasheet.
