BC807-25-QR

BC807-25-QR is a general‑purpose PNP bipolar transistor in a surface‑mount package (QR indicates RoHS/tape‑and‑reel) from the BC807 family (complement of BC817). It’s used for small‑signal switching and amplification in low‑power circuits.
Key points
- Type: PNP transistor
- Package: SMD (QR variant); RoHS compliant
- Vceo: about −45 V
- Ic max: about −0.8 A
- Gain: hFE typically in the hundreds (depends on Ic and temperature; -25 denotes a gain group)
- Emitter–Base Voltage: Vebo typically around −5 V
- Pinout: usually E–B–C in many SOT‑23 variants (check datasheet for your exact lot)
Common uses
- Switching loads
- Signal buffering and amplification
- Level shifting in low‑power circuits
Note: parameters vary with manufacturing lots and temperature. For exact figures, consult the specific BC807-25-QR datasheet from the manufacturer.

BC807-25-QR is a PNP general‑purpose transistor. Common equivalents (same function, similar Vce/Ic) include BC327, BC857 (PNP, 45 V), and 2N3906/MMBT3906 (PNP; SMD). Other BC807 variants (BC807‑16, ‑25, ‑40) from NXP/Nexperia/Onsemi can often substitute. For precise replacement, specify package (TO‑92 vs SMD) and required Ic, Vceo, and hFE.
