Descripción general

Description

BC817-40-7-F is a small-signal NPN transistor (BC817 family) in a TO-92 (through-hole) package. The -F suffix generally means RoHS/lead-free. The -40 and -7 are vendor-specific variant codes that indicate a particular current-gain (hFE) group and lot/package details; the exact hFE and limits depend on the manufacturer, so you should consult the specific datasheet for this exact part.
Typical general-purpose specs for BC817 family (vendor variants may vary):
- Vceo (collector-emitter max): ~45 V
- Ic max: ~500 mA
- Power: ~0.5–0.6 W
- hFE: broad range depending on variant (often hundreds; exact value in the chosen group)
Usage: suitable for switching and amplification in low-power circuits.
If you need precise numbers, look up the exact datasheet for BC817-40-7-F from the supplier (to confirm hFE group, max ratings, and packaging).

Features

BC817-40-F is a general‑purpose NPN transistor in a SOT‑23 package. Key features:
- Vceo: 45 V; Ic max: ~0.5 A
- Vebo: ~5 V
- hFE: from the BC817 “40” group (high gain for this family)
- Low-noise, suitable for amplification and switching
- Vce(sat) typically around 0.2–0.5 V at moderate Ic (with proper drive)
- Temperature range: −55 °C to +150 °C
- Pb‑free / RoHS compliant; SOT‑23 / 3‑pin package
Common uses: general switching, driver stages, and small‑signal amplification.

Package

SOT-23 3‑pin surface-mount package (Pb-free).

Pinout

- Pin count: 3 (SOT-23 package)
- Function: General-purpose NPN bipolar transistor (switching/amplification)
- Typical pinout (SOT-23, flat face): Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector
