BC807-25,215

BC807-25 is a variant of the BC807 family: a general-purpose PNP small-signal transistor in a TO‑92 package, complementary to BC817 (NPN).
Key points:
- Purpose: switching and amplification in low-to medium-signal circuits.
- -25 suffix: denotes a gain (hFE) grade within the BC807 family; exact gain varies by vendor and operating conditions.
- Typical ratings (approximate; check datasheet for the exact part): Vceo ≈ 45 V; Ic max ≈ 500 mA; Pd (power) around 0.3–0.6 W in TO‑92.
- Gain: hFE varies with Ic and temperature; -25 parts are mid-to-high gain variants in practice.
- Frequency: ft is in the tens to hundreds of MHz range, depending on model and conditions.
- Package: TO‑92; complement to BC817 (NPN).
Use when you need a small, general-purpose PNP transistor. For exact numbers, refer to the specific BC807-25 datasheet from the manufacturer, as parameters can vary by lot and supplier.

Manufacturer: NXP Semiconductors (formerly Philips Semiconductors).
What kind of company: Dutch multinational that designs and manufactures semiconductors and related electronic components (discrete transistors, ICs, etc.). The “-25” is a gain/grade variant; “215” is likely a date/lot code.

BC807-25 and BC807-215 are PNP general‑purpose transistors for low‑power switching and amplification.
Common applications:
- High‑side switching and pull‑ups in logic circuits
- Small‑signal amplification and buffering (audio, signal conditioning, preamps)
- Emitter‑follower/buffer stages for level shifting
- Simple regulator circuits and as a pass element in positive regulators
- Driving relays, LEDs, or protection/control circuits
Key notes:
- Similar ratings: Vceo ≈ 45 V, Ic up to ~500 mA
- -25 and -215 denote different gain (hFE) groupings; select by required gain. Check datasheet for exact specs.

TO-92 (through-hole) package. BC807-25 is the TO-92 version; “215” is likely a date/lot code, not a different package.
