Product details
Overview
SBC847CLT1 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 420–800 at IC = 2.0 mA, VCE = 5.0 V, and supports automotive-grade reliability with AEC-Q101 qualification and PPAP capability. It serves as a signal switch or amplifier in low-power interface circuits.
For engineers reviewing the SBC847CLT1 datasheet, pinout, applications, or equivalent options, key selection criteria include its 45 VCEO rating, high hFE bin (C), SOT-23 footprint compatibility, thermal performance on standard PCBs, and automotive qualification status.
Technical Context
This device operates as a discrete NPN bipolar junction transistor optimized for linear amplification and digital switching in space-constrained applications. Its design targets stable hFE across temperature (−55°C to +150°C) and low VCE(sat) (≤0.25 V at IC = 10 mA, IB = 0.5 mA) to minimize conduction loss in driver stages.
The SBC847CLT1 features ESD robustness (>4000 V HBM, >400 V MM), Pb-free/halogen-free construction, and moisture sensitivity level 1 - enabling standard surface-mount assembly without dry-pack requirements. Its fT of 100 MHz supports RF-coupled pre-amplifier use up to low-VHF frequencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial control rails with margin. |
| IC (continuous) | 100 mA - Continuous collector current handling; sufficient for LED drivers, logic-level translators, and sensor interface loads. |
| hFE (min–max) | 420–800 at IC = 2.0 mA, VCE = 5.0 V - High and tightly binned DC gain ensures predictable base drive sizing in switching designs. |
| VCE(sat) | ≤0.25 V at IC = 10 mA, IB = 0.5 mA - Low saturation voltage reduces power loss and self-heating in saturated-switch applications. |
| fT | 100 MHz - Current-gain bandwidth product; supports small-signal amplification up to ~10 MHz with usable gain. |
| RJA (FR-5) | 556 °C/W - Thermal resistance from junction to ambient on standard 1.0 × 0.75 inch FR-5 board; defines derating slope (1.8 mW/°C above 25°C). |
| ESD Rating (HBM) | >4000 V - Robust electrostatic discharge immunity simplifies handling and board-level ESD protection design. |
Pinout & Package
SOT-23 (Case 318-08) surface-mount plastic package with gull-wing leads; 3-terminal configuration, 1.9 mm pitch, 2.9 mm × 1.3 mm body size, 0.95 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal; requires current-limited drive (e.g., via series resistor) to bias transistor into active or saturation region. |
| 2 | Emitter | Current return path; connected to ground or low-side reference in common-emitter configurations. |
| 3 | Collector | Output terminal; carries load current and connects to supply rail or switched load (e.g., relay coil, LED anode). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - supports under-hood and infotainment module deployment. |
| Pb-free / RoHS compliant | Fully compliant with EU RoHS Directive 2011/65/EU and halogen-free/BFR-free - meets global environmental compliance mandates. |
| Moisture Sensitivity Level 1 | No dry-pack or baking required prior to reflow; compatible with standard J-STD-020 assembly processes. |
| High hFE bin (C) | Guaranteed minimum hFE of 420 ensures consistent switching behavior and reduced base drive current in production designs. |
| Low VBE(on) | 660–770 mV at IC = 2.0–10 mA - enables reliable turn-on from 3.3 V or 5 V logic sources without excessive base resistor power loss. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847CLT1G | Same electrical specs and SOT-23 package; differs only in marking (1G vs SBC prefix) and absence of "S" prefix denoting automotive-specific traceability controls. | Not AEC-Q101 qualified or PPAP capable; suitable for commercial-grade applications only. | Select BC847CLT1G where automotive qualification is not required and cost optimization is prioritized. |
| MMBT4401LT1G | Higher VCEO (40 V → 40 V same), but lower hFE range (100–300), higher VCE(sat) (0.75 V max), and no AEC-Q101 certification. | Lacks automotive qualification and high-gain bin; better suited for non-critical consumer switching. | Choose MMBT4401LT1G only when gain tolerance is relaxed and automotive compliance is unnecessary. |
Compared with BC847CLT1G and MMBT4401LT1G, the SBC847CLT1 provides guaranteed high hFE, full AEC-Q101 validation, and production traceability - making it the sole choice for automotive and mission-critical industrial designs requiring documented reliability.

FAQ
What is the maximum collector-emitter voltage rating for the SBC847CLT1?
The SBC847CLT1 has a maximum collector-emitter voltage (VCEO) rating of 45 V. This value is specified under test conditions of IC = 10 mA and applies to the BC847 variant group. Exceeding this voltage risks avalanche breakdown and permanent device damage, so designs must maintain at least 20% margin under worst-case transient conditions.
Is the SBC847CLT1 suitable for automotive applications?
Yes, the SBC847CLT1 is AEC-Q101 qualified and PPAP capable, with S-prefix marking indicating automotive-specific site and change control. Its thermal range (−55°C to +150°C), ESD robustness (>4000 V HBM), and process-controlled hFE binning make it appropriate for under-hood and cabin electronics where reliability and traceability are mandatory.
What is the DC current gain (hFE) range for the SBC847CLT1?
The SBC847CLT1 is the "C" gain bin, with hFE ranging from 420 to 800 when measured at IC = 2.0 mA and VCE = 5.0 V. This high and tightly bounded gain enables precise base resistor calculation and consistent switching thresholds across production lots.
Does the SBC847CLT1 require special handling due to moisture sensitivity?
No - the SBC847CLT1 has Moisture Sensitivity Level (MSL) 1, meaning it may be stored indefinitely at ≤30°C/60% RH and placed directly onto PCBs without baking or dry-pack requirements. This simplifies manufacturing logistics and eliminates moisture-related popcorning risk during reflow.
What package type does the SBC847CLT1 use, and what are its key mechanical dimensions?
The SBC847CLT1 uses the SOT-23 (Case 318-08) package: 3-pin, gull-wing leaded, 1.9 mm pin pitch, 2.9 mm × 1.3 mm body footprint, and 0.95 mm maximum height. Pin 1 is Base, Pin 2 is Emitter, and Pin 3 is Collector - confirmed by onsemi's official marking diagram and package drawings.
