Product details
Overview
BC847C,215 from Nexperia is an NPN general-purpose bipolar junction transistor in SOT23 (TO-236AB) package, rated for 45 V VCEO, 100 mA IC, and DC current gain (hFE) of 420–800 at VCE = 5 V and IC = 2 mA. It serves as a low-voltage switching or small-signal amplification device in consumer power management, LED driver bias networks, and sensor interface stages.
For engineers reviewing the BC847C,215 datasheet, BC847C,215 pinout, BC847C,215 application, or BC847C,215 equivalent, key selection criteria include its guaranteed high-current-gain bin (C-grade), SOT23 thermal performance (Rth(j-a) = 500 K/W on FR4), and compatibility with standard reflow soldering footprints per JEDEC TO-236AB.
Technical Context
This transistor operates in active or saturation mode with VBE(sat) ≤ 900 mV at IC = 100 mA / IB = 5 mA and VCE(sat) ≤ 400 mV under identical conditions. Its fT of 100 MHz supports audio-frequency amplification and fast digital switching up to ~10 MHz.
Thermal behavior is defined for FR4 PCB mounting: Ptot = 250 mW at Tamb ≤ 25 °C, with junction temperature limited to 150 °C. Absolute maximum ratings include VCBO = 50 V and VEBO = 6 V, enabling robust operation in 3.3 V/5 V rail systems with transient margin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown; supports 3.3 V/5 V logic-level switching with safety margin |
| IC | 100 mA continuous - Suitable for driving LEDs, relays, or small MOSFET gates without external heat sinking |
| hFE | 420–800 @ VCE=5 V, IC=2 mA - High and tightly binned gain enables stable biasing in amplifier and switch circuits |
| VCE(sat) | ≤ 400 mV @ IC=100 mA, IB=5 mA - Low saturation voltage minimizes power loss and self-heating in switching applications |
| fT | 100 MHz - Enables use in audio preamplifiers and medium-speed digital signal routing |
| Rth(j-a) | 500 K/W - Thermal resistance on standard FR4 PCB defines derating curve above 25 °C ambient |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 1.3 mm × 2.9 mm footprint, 1.1 mm height, and gull-wing terminations compatible with IPC-7351B standard land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires series resistor to limit IB and ensure predictable saturation |
| 2 | Emitter (E) | Common reference terminal; connected to ground or low-side return path in most switching configurations |
| 3 | Collector (C) | Output current sink node; connects to load (e.g., LED anode or relay coil) when used in low-side switch topology |
Key Features
| Feature | Design Value |
|---|---|
| High hFE bin (C-grade) | Guaranteed 420–800 gain ensures consistent bias point across production lots without trimming |
| SOT23 package | Enables high-density PCB layouts and automated placement; compatible with standard reflow profiles (J-STD-020) |
| VCE(sat) ≤ 400 mV | Reduces conduction loss in battery-powered switches, extending runtime in portable devices |
| 150 °C max junction temperature | Supports operation in enclosed industrial enclosures with ambient up to 85 °C after thermal derating |
Applications
| LED Current Control | Microcontroller GPIO Expansion |
|---|---|
|
Use Scenario: Driving discrete indicator LEDs from 3.3 V microcontroller outputs with current limiting via base resistor. IC Role / Device Role / Timing Role: Low-side NPN switch providing current sink path for LED cathode. Use Value: Guaranteed hFE ≥ 420 ensures full saturation with ≤ 200 µA base drive, preserving MCU I/O budget. |
Use Scenario: Expanding digital output capability of resource-constrained MCUs (e.g., STM32G0, RP2040) to control higher-current peripherals. IC Role / Device Role / Timing Role: Digital buffer/level shifter translating 3.3 V logic to 5 V/12 V loads. Use Value: VCEO = 45 V and IC = 100 mA allow direct interfacing with solenoids, buzzers, and optocouplers. |
| Sensor Signal Conditioning | Power Supply Enable Switching |
|
Use Scenario: Amplifying weak analog signals from thermistors or photodiodes before ADC sampling. IC Role / Device Role / Timing Role: Common-emitter small-signal amplifier stage with fixed bias network. Use Value: fT = 100 MHz and low noise figure (2–10 dB) support clean amplification of sub-10 kHz sensor outputs. |
Use Scenario: Enabling/disabling auxiliary power rails (e.g., 5 V USB peripheral supply) using MCU-controlled ON/OFF signaling. IC Role / Device Role / Timing Role: High-side or low-side enable switch in linear regulator or LDO control path. Use Value: Low VCE(sat) (< 400 mV) limits voltage drop and avoids brown-out during rail activation. |
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 |
|---|---|---|---|
| BC847BW,115 | Same SOT23 package but with ±10 % hFE tolerance (450–550); tighter gain distribution than BC847C's 420–800 range | Better suited for precision biasing where narrow hFE spread reduces calibration effort | Select when circuit stability depends on predictable gain rather than maximum gain headroom |
| MMBT3904LT1G | Higher VCEO (40 V vs. 45 V), lower hFE min (100 vs. 420), and wider gain spread (100–300) | Acceptable for basic switching but not recommended for low-base-drive amplification due to lower gain guarantee | Choose only if legacy design reuse or multi-source qualification mandates Onsemi compatibility |
Compared with BC847C,215, BC847BW,115 offers tighter hFE control at the cost of reduced maximum gain, while MMBT3904LT1G sacrifices guaranteed high gain for broader industry adoption-making BC847C optimal for new designs prioritizing low-base-drive efficiency and thermal margin.

FAQ
What is the maximum operating temperature for BC847C,215?
The BC847C,215 has a maximum junction temperature (Tj) of 150 °C and storage temperature range of −65 °C to +150 °C. When mounted on FR4 PCB with single-sided copper, its thermal resistance is 500 K/W, so ambient must be derated to ≤ 85 °C at full 100 mA load to maintain safe junction temperature.
Is BC847C,215 suitable for automotive applications?
No. BC847C,215 is not automotive-qualified. The datasheet explicitly states non-automotive qualification per Revision History v.13. For automotive use, Nexperia offers the BC847C-Q series with AEC-Q101 qualification, extended temperature testing, and PPAP documentation.
How does the marking code '1G' identify BC847C,215?
The top-side marking '1G%' (where % is manufacturing site code) uniquely identifies BC847C in SOT23 packaging per Nexperia's marking table. This distinguishes it from BC847A ('1E%') and BC847B ('1F%'), enabling visual verification of gain bin during assembly and inspection.
Can BC847C,215 replace BC847B in existing designs?
Yes, with functional improvement: BC847C offers higher minimum hFE (420 vs. 200), enabling lower base drive current and improved saturation margin. However, verify that circuit biasing remains stable across the wider gain range (420–800) and confirm no unintended gain-related oscillation in amplifier configurations.
