Specs side by side
2 parts compared · 21 differing specs across 21 total parameters.
| Parameter | ||
|---|---|---|
| Voltage - Collector Emitter Breakdown | 45 V | - |
| Operating temperature | 150°C(TJ) | - |
| Supply voltage | - | VCEO 45V; IC 100mA; Ptot 250mW in SOT-23 (mind the smaller thermal budget). |
| Frequency - Transition | 300MHz | - |
| Memory & Peripherals | - | Pinout 1 = Base, 2 = Emitter, 3 = Collector - the standard SOT-23 BJT footprint shared with MMBT3904 and BC817. |
| Case | TO-226-3, TO-92-3 (TO-226AA) | SOT-23 |
| Package | Bulk | - |
| Compatibility Level | - | Functional Equivalent |
| Core & Architecture | - | The surface-mount BC547B: 45V, 100mA, gain group B, in SOT-23. |
| Current - Collector (ic) | 100 mA | - |
| Current - Collector Cutoff | 15nA (ICBO) | - |
| Dc Current Gain (hfe) (min) @ Ic, Vce | 110 @ 2mA, 5V | - |
| Fet Type | NPN | - |
| Firmware Notes | - | For SMD new builds this is the natural BC547 translation. Confirm the power dissipation budget: SOT-23 packages 250mW where TO-92 carried 500mW. |
| Hardware Notes | - | SOT-23 pads. Same footprint as MMBT3904, so both can populate one land pattern - the electrical difference, not the pads, is what to check. |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| Mounting | Through Hole | - |
| Power - Max | 500 mW | - |
| Reference Part | - | BC547 |
| Sourcing Advantage | - | Commodity reels; the workhorse small-signal NPN of Chinese SMD production. |
| Vce Saturation (max) @ Ib, Ic | 600mV @ 5mA, 100mA | - |
