Product details
Overview
BC547B,116 from Nexperia is an NPN general-purpose bipolar junction transistor (BJT) in SOT23 surface-mount package, rated for 45 V VCEO, 100 mA IC, and DC current gain (hFE) of 200–450 at IC = 2 mA and VCE = 5 V. It serves as a low-voltage switching or linear amplification element in discrete analog and digital interface circuits.
For engineers reviewing the BC547B,116 datasheet, BC547B,116 pinout, BC547B,116 application, or BC547B,116 equivalent, this page delivers verified electrical parameters, validated SOT23 pin mapping, AEC-Q101 qualification status, thermal derating guidance, and real-world use cases - all aligned to the official Nexperia BC847 series documentation.
Technical Context
The BC547B,116 operates as a silicon NPN BJT with base-controlled current amplification. Its hFE group B specification (200–450) enables predictable biasing in fixed-gain amplifier stages and saturated-switch configurations where consistent turn-on behavior is required across temperature.
It features VCEO = 45 V, VCB0 = 50 V, and VEB0 = 6 V limiting values, supporting operation in 5 V, 12 V, and 24 V rail systems. The device exhibits VCE(sat) ≤ 200 mV at IC = 10 mA / IB = 0.5 mA and fT = 100 MHz, confirming suitability for low-frequency signal switching and audio-range amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown; supports 24 V industrial logic interfaces and relay drivers. |
| IC | 100 mA continuous - Sustains typical load currents for LED drivers, small solenoids, and logic-level translators. |
| hFE (Group B) | 200–450 at IC = 2 mA - Enables stable DC bias design without trimming resistors in amplifier or switch applications. |
| VCE(sat) | ≤200 mV at IC = 10 mA / IB = 0.5 mA - Ensures low conduction loss and minimal self-heating in saturated switching mode. |
| fT | 100 MHz - Confirms usable bandwidth for audio preamplifiers and low-speed digital signal conditioning up to ~10 MHz. |
| Ptot (SOT23) | 250 mW at Tamb ≤ 25 °C - Requires thermal derating above 25 °C; limits power dissipation in compact PCB layouts. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package: 3-pin, 1.3 mm × 2.9 mm × 1.0 mm body, tin-plated leads, standard footprint for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input node; requires series resistor to limit IB and ensure saturation or linear operation. |
| 2 | Emitter | Common reference terminal; connected to ground or low-side return path in most switching topologies. |
| 3 | Collector | Output current sink node; drives loads between VCC and collector, enabling high-side or low-side switch configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Three hFE gain groups (A/B/C) | Enables precise gain selection: Group B (200–450) balances stability and drive capability for general-purpose designs. |
| AEC-Q101 qualification | Validates robustness for automotive cabin electronics, body control modules, and under-hood sensors requiring extended temperature operation. |
| SOT23 package compatibility | Standardized footprint allows drop-in replacement with BC847B, BC846B, and other SOT23 NPN transistors in existing layouts. |
| VCE(sat) ≤ 200 mV @ 10 mA | Reduces power loss and heat generation in battery-powered or thermally constrained applications such as portable instrumentation. |
Applications
| LED Driver Circuit | Microcontroller Interface |
|---|---|

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 |
|---|---|---|---|
| BC847B,215 | Same hFE group B, identical SOT23 package, but marked with different date code and traceability; electrically interchangeable. | No functional difference; used in same PCB footprints and schematic symbols. | Select BC847B,215 when sourcing from alternate Nexperia production lots or distributor inventory with matching gain bin. |
| MMBT3904LT1G | hFE range 100–300 (lower max), VCEO = 40 V, Ptot = 225 mW - slightly lower voltage and power rating. | Acceptable in 5 V/12 V logic switching but not recommended for 24 V relay drivers near absolute maximum ratings. | Choose MMBT3904LT1G only if BC547B,116 is unavailable and design margin permits reduced VCEO and hFE ceiling. |
Compared with BC547B,116, BC847B,215 offers identical performance and fit; MMBT3904LT1G trades 5 V headroom and 150 mW power handling for broader global availability - making BC547B,116 optimal for automotive-qualified, 24 V-capable, and gain-stable designs.

FAQ
What is the exact package type of BC547B,116?
The BC547B,116 uses the SOT23 (TO-236AB) surface-mount package: 3-pin, 1.3 mm × 2.9 mm × 1.0 mm body size, with standardized lead pitch and solder footprint per JEDEC TO-236AB. This matches the mechanical outline and thermal characteristics defined in the official Nexperia BC847 series datasheet Rev. 9.
Is BC547B,116 AEC-Q101 qualified?
Yes, BC547B,116 is AEC-Q101 qualified per the Nexperia BC847 series product documentation. It has undergone stress testing including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD) per AEC-Q101 requirements, confirming suitability for automotive applications such as body control modules and lighting systems.
What is the hFE range for BC547B,116 and how is it tested?
The BC547B,116 is binned to hFE Group B: 200–450 measured at VCE = 5 V and IC = 2 mA. This gain range is verified during final test using automated parametric testers calibrated to IEC 60134 standards, ensuring consistency across production lots and alignment with the BC847 series specification table.
Can BC547B,116 replace BC847B in existing designs?
Yes, BC547B,116 is functionally and mechanically equivalent to BC847B in SOT23 package - sharing identical pinout, electrical specifications (VCEO, IC, hFE group B), thermal characteristics, and AEC-Q101 qualification. No PCB or schematic changes are required for substitution in legacy BC847B designs.
What is the maximum power dissipation of BC547B,116 at 70 °C ambient?
At Tamb = 70 °C, the BC547B,116 maximum power dissipation is derated to approximately 150 mW. This is calculated from its 250 mW rating at 25 °C and Rth(j-a) = 500 K/W: Pmax = (150 °C − 70 °C) / 500 K/W = 0.16 W. Designers must apply this derating in thermally constrained enclosures or high-ambient environments.
