Vishay 40 kHz IR Receiver Module Through Hole 2.5 V to 5.5 V 45 m Range ±45 ° TSOP4840

The Vishay TSOP4840 is a highly sensitive 40 kHz IR receiver module designed for remote control systems requiring reliable signal reception. It integrates a PIN photodiode and a preamplifier within a compact mold package with dimensions 6.95 mm height, 6 mm length, and 6 mm width, and features a 3-pin through hole mount design. The unit supports a wide operating voltage range from 2.5 V to 5.5 V and draws a nominal supply current of 700 μA, making it energy efficient for battery-powered devices.

This IR receiver module offers a maximum transmission distance of 45 meters and an angular half transmission distance of ±45 degrees, delivering robust reception angles to facilitate remote control operation in different device orientations. Its internal IR filter enhances noise immunity by reducing spurious pulses from Wi-Fi and compact fluorescent lamp sources, contributing to stable and accurate demodulation of IR signals. The demodulated output can be connected directly to microcontrollers or digital signal processing units for decoding the remote control commands.

The module is compliant with RoHS and halogen-free directives, ensuring environmentally safe manufacturing. It complies with DIN technical drawing standards that support mechanical compatibility and ease of integration. The operating temperature range from -25 °C to +85 °C ensures reliability in industrial, consumer electronics, and automation applications.

Vishay TSOP4840 is well-suited for application in household electronic appliances, automation systems, and industrial remote control solutions requiring consistent and interference-resistant IR signal reception. The through hole 3-pin configuration simplifies PCB mounting and replacement during assembly. Its high immunity to supply voltage ripple and optical noise improves performance where power stability may vary.

In summary, the Vishay TSOP4840 IR Receiver module offers a blend of compact size, advanced signal processing, and robust environmental tolerance, making it an excellent choice for integrating infrared remote control functionality in diverse electronic product designs.
