TSOP382 is compatible with all common IR remote control data formats so it can be used with common IR remotes. The operating voltage is from 2.5V to 5.5v so it can be used with both 3.3V and 5V power supplies. The TSOP38238 is similar to a normal plastic-packaged transistor in size and suitable for all kinds of infrared remote control and infrared transmission. So if you are looking for an IR Receiver diode with low power consumption, then TSOP38238 might be the right choice for you. TSOP38238 Circuit DiagramThe following is the application circuit diagram of TSOP38238. TSOP38238 Circuit Diagram How to Use TSOP38238The application circuit diagram for the TSOP38238 IR Receiver module is given above. The Resistor R1 and Capacitor C1 are used to reduce the supply ripples. TSOP38238 consists of a PIN diode, a preamplifier, and an IR filter. The receiver diode detects all frequencies of IR light, but the filter and only lets through IR at 38 kHz. Then the preamplifier modulates the signal and converts it to an electrical signal before sending it to a microcontroller. TSOP38238 CAD ModelsThe followings are TSOP38238 Symbol, Footprint, and 3D Model. TSOP38238 Symbol TSOP38238 Footprint TSOP38238 3D Model TSOP38238 Block DiagramThe following figure shows the block diagram of TSOP38238. TSOP38238 Block Diagram TSOP38238 PackageThe following diagram shows the TSOP38238 package. TSOP38238 Package TSOP38238 SpecificationAttributeValueCarrier Frequency38kHzMaximum Transmission Distance45mWavelength of Peak Sensitivity950nmOutput Current5mANumber of Pins3Mounting TypeThrough HoleDimensions5 x 4.8 x 6.95mmHeight6.95mmLength5mmMaximum Supply Voltage5.5VMinimum Supply Voltage2.5VMinimum Operating Temperature-25 °CMaximum Operating Temperature+85 °CWidth4.8mmOperating Temperature Range-25 → +85 °C TSOP38238 VS TSOP4838AttributeTSOP38238TSOP4838Carrier Frequency38kHz38kHzMaximum Transmission Distance45m45mWavelength of Peak Sensitivity950nm950nmOutput Current5mA5mANumber of Pins33Mounting TypeThrough HoleThrough HoleDimensions5 x 4.8 x 6.95mm6 x 5.6 x 6.95mmHeight6.95mm6.95mmLength5mm6mmMaximum Supply Voltage5.5V5.5VMinimum Supply Voltage2.5V2.5VMinimum Operating Temperature-25 °C-25 °CMaximum Operating Temperature+85 °C+85 °CWidth4.8mm5.6mm TSOP38238 ManufacturerVishay Intertechnology manufactures several kinds of discrete semiconductors.

TSOP38238 consists of a PIN diode, a preamplifier, and an IR filter. The receiver diode detects all frequencies of IR light, but the filter and only lets through IR at 38 kHz. What is IR receiver sensor?An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. When an object comes close to the sensor, the infrared light from the LED reflects off of the object and is detected by the receiver. Are IR receivers interchangeable?In general, IR receivers are fairly interchangeable as long as the operating parameters mentioned are met. Of course, if cosmetic / mechanical compatibility is desired, that is a challenge in itself. How does an IR receiver work?An IR receiver can detect bursts of infrared light sent by a common remote controller (like for a television), and then output a pattern of high/low signals to a Propeller I/O pin. What is an IR receiver used for?An infrared receiver is used in an IR system to control and operate devices by sending signals.
