Présentation

Equivalent

The BC327-40 is a PNP transistor. Equivalent alternatives include:
- BC557B (similar specs, higher gain)
- 2N3906 (common PNP, lower current)
- BC328 (close match, slightly different gain)
- 2SA1015 (Japanese equivalent)
Check datasheets for exact parameters like current (500mA), voltage (45V), and hFE (250-630). Substitutes may vary slightly in gain or power handling.

Pinout

The BC327-40 is a PNP bipolar junction transistor (BJT) with 3 pins (TO-92 package):
1. Emitter (E) – Connects to the higher voltage (more negative for PNP).
2. Base (B) – Controls conduction; bias current flows into the base.
3. Collector (C) – Output; current flows out (to a lower voltage).
Key Features:
- High current gain (hFE ≈ 250–630 @ 100mA)
- Max collector current (IC) = 800mA
- Max collector-emitter voltage (VCEO) = -45V
Commonly used in amplification, switching, and low-power applications.

Manufacturer

The BC327-40 is a PNP bipolar junction transistor (BJT) manufactured by ON Semiconductor, a well-known American semiconductor company. ON Semiconductor specializes in energy-efficient innovations, providing a wide range of power management, analog, and discrete semiconductor solutions for automotive, industrial, and consumer markets.

ON Semiconductor is a global leader, known for reliability and innovation in semiconductor technology.

Application

The BC327-40 is a PNP bipolar junction transistor (BJT) commonly used in:
1. Amplification – Audio and signal amplification in low-power circuits.
2. Switching – On/off control in relays, LEDs, and small loads.
3. Signal Inversion – Logic level shifting in digital circuits.
4. Complementary Pairs – Paired with NPN transistors (e.g., BC337) in push-pull configurations.
5. Consumer Electronics – Found in toys, radios, and small appliances.
Its high current gain (hFE up to 630) and low saturation voltage make it suitable for low-voltage, low-power applications.

Package

The BC327-40 is a PNP transistor packaged in a TO-92 type. This is a small, through-hole plastic package with three leads (Emitter, Base, Collector). It is commonly used for general-purpose amplification and switching applications. The TO-92 package is compact, cost-effective, and suitable for low-power circuits.
