概述

Description

BC807-25W is a PNP general‑purpose transistor in the BC807 family (complement to BC817). The “-25W” suffix is a vendor-specific gain/lot group, not a 25 W power rating, and varies by manufacturer.
Key points:
- Package: TO‑92 (through‑hole) or equivalent.
- Configuration: PNP small‑signal transistor.
- Vceo: about 45 V; Ic: up to ~0.5 A.
- Ptot: typically in the low‑hundreds of milliwatts (depends on mounting and ambient temperature).
- Gain (hFE): vendor‑specific for the -25W group; usually several hundred.
- Features: simple biasing, moderate speed, suitable for switching and amplification.
Applications:
- General switching/driver stages, preamplifiers, level shifting, relay drivers.
Design notes:
- Ib ≈ Ic / hFE; ensure Ic stays within max ratings.
- Check the exact datasheet for the -25W variant you’re using (hFE range, leakage, and thermal limits) to size biasing and cooling correctly.

Features

BC807-25W is a PNP silicon small-signal transistor (TO-92) from the BC807 family (complement to BC817). Key features:
- Package: TO-92 plastic
- Type: PNP, small-signal switching/amplification
- Ic max: up to ~500 mA
- Vceo: up to 45 V
- Vebo: up to ~5 V
- Pd max: about 0.6–0.8 W (at Tc=25°C)
- DC gain (hFE): wide range; grouped by gain (the -25 variant indicates a mid-range group; actual hFE varies with Ic and temp)
- Temperature range: roughly -55°C to +150°C
- Complementary to BC817 (NPN)
- Applications: low-power switching and amplification in DC/analog circuits
Note: exact values (especially hFE group and Pd) vary by manufacturer and lot. Check the specific datasheet for your part.

Package

TO-92 plastic package (three-lead) for the BC807-25W PNP small-signal transistor.

Pinout

The BC807-25W is a PNP bipolar transistor with 3 pins: emitter (E), base (B) and collector (C). It is used for low‑power amplification and switching. (Package pin order can vary by manufacturer/package — consult the specific datasheet for the exact pin numbering for your package.)

Manufacturer

- Manufacturer: Vishay Intertechnology.
- Company type: Vishay is a global (multinational) semiconductor and passive-component manufacturer, designing and producing discrete transistors, diodes, resistors, capacitors, inductors, and related components.

Application

BC807-25W is a general-purpose PNP transistor. Applications include:
- Low-power switching and small-signal amplification
- High-side switching and biasing in DC power supplies/regulators
- Emitter-follower or pre-driver stages in audio circuits
- Relay and LED driver circuits
- Level shifting and small-signal switching in microcontroller interfaces
Used where a PNP device with moderate current gain is convenient.

Equivalent

Common equivalents for the BC807-25W (PNP small-signal transistor) include BC557-25, 2N3906 (or SMD MMBT3906), 2N2907 (for higher current), and BC327 (higher-power alternative). Verify pinout, Vce, Ic and hFE before substituting.
