SOT23 Marking Code

SOT23 is commonly known for a 3 pins SMD package and is also known as SOT23-3. There is also 5 pins package (SOT23-5), and 6 pins package (SOT23-6). The SOT package is small and normally the full part number cannot be printed on the chip itself. Normally the part number is represented by a marking code printed on top of the SOT23 package.

The follows presents some of the SOT23 components marking code, which is useful for reverse engineering use.

Warning Note: Please ensure the context of the component used in the electronic design is correct. It is possible to misinterpret the part with same marking code. This marking code reference guide is meant for your convenient. Always check the datasheet to confirm if your marking code matches the part number.

Temperature of Electronic Under Hot Sun

temperature under hot sunSingapore is located near the equator and the weather here is hot all year round. Electronic installed outdoor is subjected to the fierce heat of the direct sun. As a designer, you may be wondering if your electronic can withstand the high temperature for your electronic deployment in Singapore.

We have done a simple survey to measure the temperature that the electronic can be subjected to for outdoor installation in Singapore.

Temperature of Electrical Box Under the Hot Sun

For this measurement, a digital thermometer is placed inside a black plastic box. After under the hot sun (a day without any cloud) for at least over 30minutes, the temperature inside the box is recorded.

The temperature inside the enclosed box can typically go up to 40°C to 49°C in a normal environmental temperature of 30°C to 33°C.

temperature inside a black plastic box reading of the temperature inside a black plastic box

reading of 48.8°C, the temperature inside this black box.

 

Temperature of Object Directly Under the Hot Sun

temperature under direct sun lightThe thermometer measurement probe under direct sunlight can go up to 50°C to 55°C (usually 10 to 15°C above temperature under shade).

The normal weather temperature that we always get from the weather station is a temperature of the surrounding air under a shade. No direct sunlight with the thermometer.

 

 

Designing Electronic to Operate Under the Hot Sun

Most electronic are design to operate in the range of -40°C to +85°C. For most outdoor installation, it is not too much of a problem even in a place like Singapore. For special high-temperature application, it is important to select electronic components that can withstand high temperature.

Manual Wiring on Prototyping Circuit Board, Electronic Design

Prototyping boards allows electronic components to be manually soldered and secure neatly onto a board platform. Compare to plugging the electronics component onto a temporary breadboard, a prototyping board offers a better reliability. It is robust enough for a one-time project deployment. There are many types of prototyping board to suit your prototyping needs.

Benefits of manually wired prototype circuit

  • Design changes flexibility during the development phase of the first prototype.
  • Less initial investment for proof of concept.
  • PCB Design drawing need not be drawn first.

Disadvantages

  • A Slow and Expensive method if your production quantity is large. (eg. > 10pcs)
  • Not suitable for fine pitch IC chips and components.
  • Limited choice of connectors.

 

Some samples of designed electronic prototype circuit manually wired on a prototyping circuit board.

Neat custom component layout with the point to point soldering using wire wrap wires on an FR4 prototyping board. The FR4 board prototype boards have rows/columns of holes which are inter-connection on both sides of the board. The top of the PCB is neatly mounted with through hole components, while the back of the PCB has the electronic connection with the point to point soldering.
