Product details
Overview
SBC847BLT1G from onsemi is an NPN silicon general-purpose transistor in SOT-23 package, rated for 45 VCEO, 100 mA continuous collector current, and 225 mW power dissipation on FR-5 board. It delivers DC current gain (hFE) of 200–450 at IC = 2.0 mA, VCE = 5.0 V, and exhibits VCE(sat) ≤ 0.25 V at IC = 10 mA / IB = 0.5 mA - used in low-voltage switching and signal amplification circuits in automotive body control modules.
For engineers reviewing the SBC847BLT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, 45 V breakdown rating, SOT-23 footprint compatibility, and guaranteed hFE binning (B-grade) for consistent biasing in production-level discrete amplifier and switch designs.
Technical Context
This device operates as a single NPN bipolar junction transistor with fixed emitter-base and collector-base junction structures optimized for linear amplification and saturated switching. Its thermal resistance (RJA = 556 °C/W on FR-5) and derating slope (1.8 mW/°C above 25°C) define safe operating limits under ambient-constrained PCB layouts.
The SBC847BLT1G shares the BC847B variant's electrical binning - including V(BR)CEO = 45 V, VBE(on) = 660–700 mV at IC = 2.0 mA, and fT = 100 MHz - and is specified across −55°C to +150°C junction temperature range, supporting automotive under-hood and industrial control environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum allowable voltage between collector and emitter before breakdown; sets upper rail limit for 24 V automotive logic-level switching. |
| IC (continuous) | 100 mA - Absolute max DC collector current; supports relay drivers, LED buffers, and sensor interface stages without forced cooling. |
| hFE (min–max) | 200–450 - Guaranteed DC current gain range at IC = 2.0 mA, VCE = 5.0 V; enables predictable base resistor sizing for stable bias networks. |
| VCE(sat) | ≤ 0.25 V @ IC/IB = 10 mA/0.5 mA - Low saturation voltage minimizes conduction loss in high-duty-cycle switching applications. |
| fT | 100 MHz - Transition frequency defines usable bandwidth for small-signal amplification up to ~10 MHz with gain margin. |
| RJA | 556 °C/W - Junction-to-ambient thermal resistance on standard FR-5 board; determines temperature rise per mW dissipated. |
| ESD Rating (HBM) | >4000 V - Human Body Model robustness allows handling without special ESD precautions during manual assembly. |
Pinout & Package
SOT-23 (TO-236) surface-mount plastic package, 3-pin, 1.3 mm × 2.9 mm footprint, 0.95 mm height, with gull-wing leads. Moisture sensitivity level (MSL) 1 - floor life unlimited at ≤30°C/60% RH.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal for forward-biased junction; requires current-limited drive (e.g., 1–10 kΩ series resistor) to achieve target IC. |
| 2 | Emitter | Common reference node in common-emitter configuration; tied to ground or low-side return path in switching topologies. |
| 3 | Collector | Output current sink node; connects to load (e.g., LED anode, relay coil) when used as low-side switch. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - enables use in non-safety-critical vehicle subsystems without requalification. |
| Pb-free, RoHS compliant | Meets EU Directive 2011/65/EU and halogen-free/BFR-free specifications - supports environmentally regulated industrial and consumer end products. |
| High hFE consistency (B grade) | 200–450 hFE range ensures tight gain matching across production lots, reducing calibration overhead in analog front-end designs. |
| Low VCE(sat) | ≤0.25 V at rated IC/IB reduces power loss by >30% vs. legacy general-purpose transistors, improving thermal margin in dense layouts. |
| 150°C max junction temperature | Enables operation in engine bay, power supply, or industrial motor control enclosures without derating below full current rating. |

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 |
|---|---|---|---|
| BC847BLT1G | Same electrical specs and SOT-23 package; differs only in marking (1F vs. SBC prefix) and lack of "S" prefix denoting automotive-specific traceability. | Not AEC-Q101 certified; suitable for commercial/industrial use but not automotive PPAP programs. | Select BC847BLT1G where automotive qualification is unnecessary and cost optimization is prioritized. |
| MMBT4401LT1G | Higher VCEO (40 V → 40 V), same IC (100 mA), but lower hFE min (100 vs. 200); fT = 250 MHz vs. 100 MHz. | Better high-frequency response but less DC gain stability; not AEC-Q101 qualified. | Choose MMBT4401LT1G for RF-adjacent signal conditioning where speed outweighs gain precision. |
Compared with BC847BLT1G and MMBT4401LT1G, the SBC847BLT1G uniquely combines AEC-Q101 compliance, B-grade hFE binning, and proven thermal performance on FR-5 - making it the preferred choice for automotive body electronics requiring production traceability and long-term reliability validation.

FAQ
What is the maximum junction temperature rating for the SBC847BLT1G?
The SBC847BLT1G has a specified junction and storage temperature range of −55°C to +150°C. This allows operation in under-hood automotive environments and industrial enclosures without thermal derating below full current capability, provided PCB layout maintains RJA ≤ 556 °C/W on FR-5 board.
Is the SBC847BLT1G pin-compatible with other BC847 variants like BC847ALT1G or BC847CLT1G?
Yes, the SBC847BLT1G uses the identical SOT-23 package and pinout (pin 1 = base, pin 2 = emitter, pin 3 = collector) as all BC847-series transistors. However, electrical parameters differ: BC847ALT1G has lower hFE (110–220), while BC847CLT1G offers higher hFE (420–800); substitution requires verification of gain and saturation voltage requirements.
Does the SBC847BLT1G meet automotive qualification standards?
Yes, the SBC847BLT1G is AEC-Q101 qualified and PPAP capable, with S-prefix marking indicating automotive-specific site and change control requirements. It also meets ESD ratings >4000 V (HBM) and >400 V (MM), and is Pb-free, halogen-free, and RoHS compliant - fulfilling Tier 1 supplier requirements for non-safety-critical vehicle systems.
What is the typical noise figure of the SBC847BLT1G in small-signal amplifier configurations?
The SBC847BLT1G has a noise figure of 10 dB at IC = 0.2 mA, VCE = 5.0 V, RS = 2.0 kΩ, f = 1.0 kHz, and BW = 200 Hz. This makes it suitable for low-frequency sensor amplification (e.g., thermistor or strain gauge interfaces) where moderate noise performance is acceptable and gain stability is prioritized over ultra-low-noise operation.
Can the SBC847BLT1G be used in linear amplifier mode, or is it intended only for switching?
The SBC847BLT1G supports both saturated switching and linear amplification modes. Its fT = 100 MHz and well-characterized hFE vs. IC curves (Figures 19–20) confirm suitability for Class-A audio preamplifiers and analog signal conditioning up to ~10 MHz, provided biasing remains within SOA limits defined in Figure 38.
