Product details
Overview
SBC847BLT1G-M01 from onsemi is an NPN epitaxial silicon transistor in SOT-23 package, rated for 45 V VCEO, 100 mA IC, and 310 mW power dissipation, with hFE of 200–450 (Class B), used in low-voltage switching and small-signal amplification circuits such as level shifters and LED drivers.
For engineers reviewing the SBC847BLT1G-M01 datasheet, pinout, applications, or equivalent options, key selection criteria include VCEO/VCBO ratings, hFE classification, saturation voltage at defined IC/IB, thermal resistance, and SOT-23 footprint compatibility in space-constrained PCB layouts.
Technical Context
This device operates as a general-purpose bipolar junction transistor with epitaxial base construction, optimized for linear amplification and digital switching in ambient temperatures from −65 °C to +150 °C. Its low noise figure (2.0–10.0 dB) and fT of 300 MHz support audio-frequency and low-speed digital signal conditioning.
The SBC847BLT1G-M01 exhibits VBE(on) = 580–700 mV at IC = 2 mA and VCE = 5 V, and VCE(sat) ≤ 250 mV at IC = 10 mA / IB = 0.5 mA - enabling efficient low-power switching in battery-operated sensor interfaces and logic-level translators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - maximum collector-emitter voltage before breakdown; defines safe operating range in 3.3 V/5 V logic interface circuits. |
| IC (DC) | 100 mA - continuous collector current limit; supports driving LEDs, relays, or small MOSFET gates without external heat sinking. |
| hFE Class | B (200–450) - mid-range DC current gain; ensures predictable base drive requirements for consistent switching thresholds. |
| VCE(sat) | ≤250 mV @ IC=10 mA/IB=0.5 mA - low saturation voltage minimizes power loss and self-heating in active-low switch configurations. |
| fT | 300 MHz - current gain bandwidth product; enables stable operation up to ~10 MHz in small-signal amplifier stages. |
| RθJA | 403 °C/W - junction-to-ambient thermal resistance on standard FR-4 PCB; requires derating above 25 °C for sustained >150 mW operation. |
Pinout & Package
SBC847BLT1G-M01 is housed in a surface-mount SOT-23 (TO-236) 3-lead plastic package with standard pin assignment: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Control terminal for minority-carrier injection | Receives base current to bias transistor into active/saturation; requires current-limiting resistor in most digital switch applications. |
| 2 (Emitter) | Source of majority carriers (electrons) | Typically tied to ground or low-side reference; forms common-emitter configuration with fixed emitter potential. |
| 3 (Collector) | Sink for majority carriers | Connected to load (e.g., LED anode or pull-up rail); carries full load current when saturated. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) at IC = 10 mA | Ensures <250 mV drop across collector-emitter during switching, reducing conduction loss in portable power management. |
| hFE classification B (200–450) | Provides tight gain distribution for predictable base drive design without post-production binning or trimming. |
| 310 mW power dissipation (TA = 25 °C) | Supports continuous operation in compact consumer electronics enclosures without forced airflow or heatsinking. |
| Low noise figure (2.0–10.0 dB) | Enables use in preamplifier stages of analog sensor signal chains where SNR preservation is critical. |
Applications
| LED Driver Circuit | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving discrete indicator LEDs from 3.3 V MCU outputs with current limiting via base resistor. IC Role / Device Role / Timing Role: Low-side switch controlling LED cathode connection to ground. Use Value: VCE(sat) ≤ 250 mV ensures >95% of supply voltage reaches LED forward drop, maximizing brightness at minimal I/O loading. |
Use Scenario: Amplifying weak analog sensor signals (e.g., thermistor divider output) before ADC sampling. IC Role / Device Role / Timing Role: Common-emitter small-signal amplifier stage with fixed bias network. Use Value: fT = 300 MHz and hFE = 200–450 enable stable 10× voltage gain up to 1 MHz without oscillation or phase shift. |
| Level Shifter (5 V ↔ 3.3 V) | Relay Driver Interface |
Use Scenario: Translating 5 V logic signals to 3.3 V compatible levels for mixed-voltage microcontrollers. IC Role / Device Role / Timing Role: Active-low open-collector translator with pull-up on collector side. Use Value: VCEO = 45 V and fast turn-on/off times allow reliable translation across multiple voltage domains without latch-up risk. |
Use Scenario: Switching 12 V relay coils using 3.3 V microcontroller outputs. IC Role / Device Role / Timing Role: Saturated switch providing galvanic isolation between control and load circuits. Use Value: IC = 100 mA rating and low VCE(sat) ensure full coil energization while minimizing transistor self-heating during extended duty cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching and amplification applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BMTF | Same hFE class (B), identical SOT-23 package, but no "S" prefix; marked "8BB" instead of "M01". | No functional difference; both meet same JEDEC specs and onsemi BC847 family electrical limits. | Select BC847BMTF if standard marking and tape-and-reel packaging without special suffixes are preferred. |
| MMBT847BLT1G | Identical electrical specs and SOT-23 footprint; differs only in part numbering convention (MMBT prefix vs. SBC prefix). | Same use cases; MMBT847BLT1G is widely stocked by distributors and shares full cross-reference with SBC847BLT1G-M01. | Choose MMBT847BLT1G for broader second-source availability and simplified procurement across global supply channels. |

FAQ
What is the maximum collector-emitter voltage rating for SBC847BLT1G-M01?
The SBC847BLT1G-M01 has a VCEO rating of 45 V, meaning it can safely sustain up to 45 volts between collector and emitter under DC conditions at TA = 25 °C. This rating applies to the BC847 variant group per onsemi's BC846/D datasheet, and must be derated at elevated ambient temperatures per the device's thermal characteristics.
Does SBC847BLT1G-M01 have a specified noise figure, and what is its typical value?
Yes, the SBC847BLT1G-M01 has a noise figure specification of 2.0–10.0 dB, measured at VCE = 5 V, IC = 200 μA, RG = 2 kΩ, and f = 1 kHz. This range reflects variation across hFE classes and operating conditions, and is confirmed in the Electrical Characteristics table of the official BC846/D datasheet for BC847 devices.
What is the hFE classification for SBC847BLT1G-M01, and how does it affect base drive design?
The SBC847BLT1G-M01 is classified as hFE Class B, with a guaranteed DC current gain range of 200–450 at VCE = 5 V and IC = 2 mA. This allows predictable calculation of required base current - for example, to switch 10 mA collector current, 22–50 μA base drive suffices - simplifying resistor selection in digital interface circuits.
Is SBC847BLT1G-M01 compatible with standard SOT-23 footprints used for other BC847 variants?
Yes, the SBC847BLT1G-M01 uses the industry-standard SOT-23 (TO-236) package with 1.3 mm pitch and defined land pattern dimensions. Its pinout (Base-Emitter-Collector on Pins 1–2–3) matches all BC847-family variants including BC847BMTF and MMBT847BLT1G, enabling direct PCB layout reuse across qualified alternatives.
What is the thermal resistance (RθJA) of SBC847BLT1G-M01, and how does it impact power handling?
The SBC847BLT1G-M01 has an RθJA of 403 °C/W on a standard FR-4 PCB (76 mm × 114 mm, 1.57 mm thick, minimum copper land). At 25 °C ambient, this limits usable power dissipation to 310 mW; above that temperature, allowable power drops by 2.48 mW/°C - critical for thermal margin analysis in enclosed or high-temperature environments.
