BC557 PNP Transistor General Purpose

BC556, BC557 and BC558 PNP Amplifier Transistors are not only popular today but very ancient, it is used as a General Purpose device and a popular LED control in small products.

BC557 PNP Transistor - Amplifier

This Silicon device along with some others replaced Germanium Devices in Preamplifiers and Portable Transistor Radios  and Portable Tape Recorders. A Complement is the BC547 NPN General Purpose Transistor. Now for Specs 45V, 100mA, 200 beta approx.

BC557 PNP Transistor General Purpose

I will explain in a way most can comprehend. Do not use this for circuits working around 30-40 Volts. Use it for circuits upto 24 volts on the safer side. (45 V max rating)

Do not subject the base emmiter (diode path ) to any kind of reverse bias. That includes kickback from coils of relays or solenoids. This will damage the device, protect with a diode if needed.

Do not work it hot, it is not a metal device, use it for small signal. Reed Relay driving is possible, Single LED drive is also ok. Microphone Amplifiers, Bass, Treble and Presence controls. LED Flashers, Graphic Equalizers are things you could make with this, using Filter Circuits.

Continuous current rating is 100mA, this is fine if transistor is saturated or fully on, when voltage across device is very less and current is 100mA. Power Dissipation is tolerable. If Transistor is just partially ON or Switching fast, The Power Dissipation can peak and eventually damage the device. The device can manage to survive say 500 mW or a little more, but remember that the battery is draining fast.

A 200 Beta is pretty good, it depends on temperature, voltage and other factors. 100uA base drive can can turn on a LED at 20mA in the collector path. You can drive a LED from Opamp or Logic IC using this device, just add a 22k in series to the base.

Design products that are safe, last long and use very little power. That is pretty Green.

Circuit Note CN0147 - Powering a Fractional-N Voltage Controlled Oscillator (VCO) with Low Noise LDO Regulators for Reduced Phase Noise

Circuit Note CN0147 - Analog Devices

This circuit uses low noise, low dropout (LDO) linear regulators to supply power to a wideband integrated PLL and VCO. Wideband voltage controlled oscillators (VCOs) may have increased sensitivity to power supply noise, hence, ultralow noise regulators are recommended for best performance.

The evaluation board, which uses the ADP150 LDOs to power the ADF4350. The ADP150 represents the industry’s lowest noise LDO in the smallest package at the lowest cost.
