Product details
Overview
BC847AMB,315 from Nexperia is an AEC-Q101 qualified NPN general-purpose transistor in a leadless ultra-small SOT883B package, rated for 45 V VCEO, 100 mA IC, and DC current gain (hFE) of 110–220 at 2 mA/5 V; used for low-power switching and amplification in space-constrained mobile and automotive signal paths.
For engineers reviewing the BC847AMB,315 datasheet, BC847AMB,315 pinout, BC847AMB,315 application, or BC847AMB,315 equivalent, this part supports compact PCB layouts requiring high thermal efficiency, low-profile mounting, and automotive-grade reliability under ambient temperatures from −55 °C to +150 °C.
Technical Context
The BC847AMB,315 operates as a discrete bipolar junction transistor with base-controlled current amplification, optimized for linear amplification and saturated switching in low-voltage analog and digital interface circuits. Its hFE range (110–220) and low VCE(sat) (90–200 mV at 10 mA/0.5 mA) enable stable biasing in battery-powered sensor front-ends and LED drivers.
Thermal performance is defined by Rth(j-a) = 500 K/W on FR4 PCB, and its 0.37 mm height and 1.0 × 0.6 mm footprint support high-density routing in portable electronics. AEC-Q101 qualification confirms suitability for automotive body control modules and infotainment power management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown; sets safe operating range for 3.3 V/5 V logic-level switching. |
| IC | 100 mA - Continuous collector current capacity; supports driving small relays, LEDs, or logic gates without external heat sinking. |
| hFE | 110–220 - DC current gain at VCE = 5 V, IC = 2 mA; enables predictable base drive sizing for stable amplifier or switch bias networks. |
| VCE(sat) | 90–200 mV at IC = 10 mA / IB = 0.5 mA - Low saturation voltage minimizes conduction loss in high-efficiency switching applications. |
| Package | SOT883B - Leadless 3-terminal surface-mount package (1.0 × 0.6 × 0.37 mm); enables >30% board area reduction vs. SOT23 while maintaining comparable power dissipation (250 mW). |
| AEC-Q101 | Qualified - Validated for automotive use per stress test standard; ensures reliability in engine control units and ADAS sensor interfaces. |
Pinout & Package
SOT883B is a leadless ultra-small plastic package with three solder lands, measuring 1.0 mm × 0.6 mm × 0.37 mm height and featuring a transparent top view with pin 1 (base) marked by binary code "0100 0001".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal for forward-biased junction; requires current-limited drive (e.g., 0.5 mA typical for 10 mA collector output) to ensure reliable saturation. |
| 2 | Emiter | Common reference node in common-emitter configuration; connected to ground or low-side return path in switching circuits. |
| 3 | Collector | Output current terminal; handles up to 100 mA continuous load; routed to VCC-side loads such as LEDs or microcontroller input protection networks. |
Key Features
| Feature | Design Value |
|---|---|
| Leadless ultra-small SMD | Reduces PCB real estate by >30% vs. SOT23 while maintaining thermal performance via direct copper pad contact. |
| Low package height (0.37 mm) | Enables stacking with thin batteries or conformal coating in ultra-thin mobile handsets and wearables. |
| Power dissipation (250 mW) | Matches SOT23 capability despite smaller size-achieved through optimized thermal path to PCB copper. |
| AEC-Q101 qualification | Validates robustness across temperature cycling, humidity, and mechanical shock for automotive cabin electronics. |
Applications
| Automotive Body Control Module | Smartphone LED Backlight Driver |
|---|---|

Use Scenario: Level-shifting and fault isolation between USB-C CC logic and 3.3 V system MCU. IC Role / Device Role / Timing Role: Bidirectional signal buffer for CC line voltage translation and overvoltage clamping. Use Value: Fast transition frequency (100 MHz) supports clean edge integrity at USB PD negotiation speeds; low Cc (1.5 pF) prevents signal distortion. |
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 |
|---|---|---|---|
| BC847BMB,315 | Higher hFE (200–450), same VCEO/IC/package | Better suited for low-base-drive amplification where gain stability at low IC is critical | Select when bias network must minimize base current draw or operate reliably below 1 mA IB |
| MMBT3904LT1G | SOT23-3 package (2.9 × 1.3 × 1.0 mm), hFE 100–300, non-AEC-Q101 | Compatible for non-automotive consumer designs where board space is less constrained | Choose for cost-sensitive industrial or computing applications where AEC-Q101 is not required |

FAQ
What is the maximum allowable junction temperature for BC847AMB,315?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in Table 6 of the Nexperia datasheet. Operation beyond this limit risks permanent degradation of hFE and increased leakage currents. Derating is required above 25 °C ambient per the Rth(j-a) = 500 K/W thermal resistance value.
Is BC847AMB,315 compatible with reflow soldering only?
Yes-Nexperia explicitly states that reflow soldering is the only recommended method. Wave or hand soldering is not supported due to thermal stress sensitivity and the absence of leads. The device requires adherence to JEDEC J-STD-020 moisture sensitivity level (MSL) guidelines and profile-specific peak temperature limits.
How does the SOT883B package affect thermal performance compared to SOT23?
Despite its 60% smaller footprint, SOT883B achieves comparable 250 mW power dissipation to SOT23 by optimizing thermal conduction through direct solder land contact and minimal die-to-pad distance. Its Rth(j-a) of 500 K/W matches typical SOT23 values when mounted on standard FR4 with single-sided copper.
What does the marking code "0100 0001" indicate on BC847AMB,315?
This 8-bit binary code identifies the BC847AMB variant per Nexperia's SOT883B marking convention. It distinguishes the AMB gain bin (hFE = 110–220) from BMB (200–450) and CMB (420–800) variants, enabling automated optical inspection and traceability in high-volume assembly lines.
