Product details
Overview
BC847C/AU,215 from NXP Semiconductors is an NPN general-purpose transistor in SOT23 surface-mount plastic 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 compact consumer and industrial PCBs.
For engineers reviewing the BC847C/AU,215 datasheet, BC847C/AU,215 pinout, BC847C/AU,215 application, or BC847C/AU,215 equivalent, key selection criteria include its SOT23 footprint compatibility, guaranteed hFE group C performance, 250 mW power dissipation at Tamb ≤ 25 °C, and suitability for discrete logic-level interface and signal buffering in space-constrained designs.
Technical Context
This transistor operates as a silicon NPN bipolar junction device with base-controlled current amplification. Its design supports linear amplification and saturated switching modes, with VBE = 580–700 mV at IC = 2 mA and VCE = 5 V, and VCE(sat) ≤ 200 mV at IC = 10 mA / IB = 0.5 mA.
Thermal behavior is defined for FR4 PCB mounting with single-sided copper: Rth(j-a) = 500 K/W, enabling operation from −65 °C to +150 °C ambient. The device exhibits fT = 100 MHz and low capacitance (Cc ≤ 1.5 pF, Ce ≈ 11 pF), supporting stable performance up to mid-frequency analog and digital signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum collector-emitter voltage before breakdown; defines safe operating range in low-voltage switching circuits. |
| IC | 100 mA continuous - Absolute maximum collector current; sets upper limit for load-driving capability in discrete stages. |
| hFE (Group C) | 420–800 at VCE = 5 V, IC = 2 mA - Guaranteed DC current gain spread; enables predictable biasing without individual device trimming. |
| VCE(sat) | ≤ 200 mV at IC = 10 mA / IB = 0.5 mA - Low saturation voltage ensures minimal conduction loss in switch-mode applications. |
| Ptot | 250 mW at Tamb ≤ 25 °C - Total power dissipation limit on standard FR4; determines thermal derating requirements in real layouts. |
| fT | 100 MHz - Transition frequency; confirms usability in audio and low-MHz digital signal conditioning without instability. |
| Cc | ≤ 1.5 pF - Collector-base capacitance; contributes to high-frequency response limitation and layout-sensitive noise coupling. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package: 3-lead, 1.3 mm × 2.9 mm × 1.0 mm body, 0.95 mm lead pitch, designed for reflow soldering per JEDEC J-STD-020.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input terminal; requires series resistor to limit IB and ensure reliable turn-on/turn-off in switching use. |
| 2 | Emitter | Common reference node for NPN configuration; connected to ground or low-side return path in most applications. |
| 3 | Collector | Output current sink terminal; interfaces with load (e.g., LED, relay coil, logic gate input) in common-emitter topology. |
Key Features
| Feature | Design Value |
|---|---|
| Three hFE gain groups (A/B/C) | Enables precise current gain selection per circuit requirement-BC847C/AU,215 delivers 420–800 hFE for consistent amplification without external feedback tuning. |
| SOT23 package | Standardized 3-pin footprint compatible with automated pick-and-place and reflow processes; supports high-density board layouts. |
| VCEO = 45 V / VCBO = 50 V | Provides 5 V overhead above typical 3.3 V/5 V rail systems, allowing robust operation under transient overvoltage conditions. |
| VBE(sat) ≤ 900 mV at IC = 100 mA | Ensures sufficient base drive margin when interfacing with 3.3 V microcontroller GPIOs without level-shifting circuitry. |
| Low noise figure (NF = 2–10 dB) | Supports clean small-signal amplification in sensor front-ends and audio preamp stages where SNR preservation is critical. |
Applications

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/AU,215 | hFE = 200–450 (Group B); otherwise identical electrical and mechanical specs. | Lower gain reduces base drive sensitivity but increases consistency in high-volume production where tighter hFE distribution is preferred. | Select BC847B/AU,215 when circuit tolerates lower current gain and benefits from reduced hFE variation across temperature. |
| MMBT3904LT1G | Same SOT23 package; hFE = 100–300 (min–max), VCEO = 40 V, Ptot = 310 mW, fT = 300 MHz. | Higher fT suits RF biasing; lower VCEO restricts use in 45 V tolerant designs; wider hFE spread demands more conservative bias design. | Choose MMBT3904LT1G only if higher transition frequency is required and 40 V VCEO suffices for the target application voltage rails. |
Compared with BC847C/AU,215, BC847B/AU,215 offers tighter hFE control at lower gain, while MMBT3904LT1G trades guaranteed high hFE for greater bandwidth and higher power handling-neither is pin-compatible nor drop-in; all require validation of bias network and thermal margin.

FAQ
What is the exact package type of BC847C/AU,215?
The BC847C/AU,215 uses the SOT23 (TO-236AB) surface-mount plastic package, with dimensions 2.9 mm × 1.3 mm × 1.0 mm and 0.95 mm lead pitch. This is confirmed by NXP's ordering information table and package outline Figure 13 in the BC847_SER datasheet Rev. 8.
Does BC847C/AU,215 have a guaranteed minimum hFE value?
Yes, BC847C/AU,215 belongs to hFE Group C and guarantees a minimum DC current gain of 420 at VCE = 5 V and IC = 2 mA, with a typical value of 520 and maximum of 800 under those same test conditions.
Can BC847C/AU,215 replace BC847B/AU,215 without circuit modification?
No-while both share identical package, voltage/current ratings, and pinout, BC847C/AU,215 has higher hFE (420–800) than BC847B/AU,215 (200–450). Substituting may cause excessive collector current or thermal stress if the original bias network was designed for lower gain.
What is the maximum power dissipation of BC847C/AU,215 on a standard FR4 PCB?
BC847C/AU,215 has a total power dissipation (Ptot) rating of 250 mW at ambient temperature ≤ 25 °C when mounted on an FR4 PCB with single-sided copper and standard footprint, as specified in Table 6 of the NXP BC847_SER datasheet.
Is BC847C/AU,215 suitable for automotive applications?
No-BC847C/AU,215 is not automotive-qualified. The NXP BC847_SER datasheet explicitly states in Section 12.3 that unless otherwise specified, non-automotive qualified products like BC847C/AU,215 are not tested or warranted for automotive use, including AEC-Q101 stress testing or temperature cycling compliance.
