Description
BC846BMB,315 is a general‑purpose NPN small-signal transistor in an SOT-23 (3‑lead) package. It’s part of the BC846 family (low‑noise, medium‑gain “B” grade).
Key points:
- Type: NPN, small‑signal transistor
- Package: SOT‑23; MB suffix indicates the vendor’s SMD variant; 315 is typically a date/lot code, not a electrical spec
- Electricals (typical, vendor varies): Vceo ≈ 45 V; Ic up to ~100 mA; hFE in the B group roughly 160–320 at Ic ≈ 2 mA
- Frequency: fT in the hundreds of MHz, suitable for moderate-speed amplification and switching
- Applications: general‑purpose amplification, buffering, sensors, small‑signal switching
- Pinout: vendor‑specific; verify with the datasheet for exact emitter/base/collector arrangement in your lot
For exact figures, consult the manufacturer’s datasheet for the BC846BMB variant you have.

Equivalent
BC846BMB,315 is the SOT‑23 BC846B NPN. Direct equivalents are BC846B parts from other manufacturers (ON Semiconductor, Vishay, Rohm, Diodes, Nexperia). Close SMD substitutes with similar specs (verify Vceo ≈80 V, Ic≈100 mA, hFE group B) include BC846B from any vendor; if unavailable, choose a similar SMD NPN (e.g., BC847B or MMBT3904) only after checking key ratings.
Features
BC846BMB,315 Features (concise)
- NPN general-purpose small-signal transistor
- SMD package (SOT-23), marking MB; tape/ reel
- Vceo = 45 V; Ic max = 100 mA
- Gain (hFE) in the B family: roughly 200–450 (typical mid-range)
- Low-noise suitable for amplification and switching
- Transition frequency (fT) in the hundreds of MHz range (fast enough for modest-speed apps)
- Wide operating temperature: -55°C to +150°C
- RoHS compliant, lead-free
- Complementary to BC856 family
Note: exact hFE range and fT vary by lot; BC846B is the mid-gain variant (A: ~110–220, B: ~200–450, C: ~420–800).
