Overview

The TSAL6200 is a high-power infrared emitting diode featuring a 940nm peak wavelength, housed in a standard 5mm (T-1 3/4) clear plastic package. It is designed for high radiant intensity and high reliability, making it a staple component for infrared data transmission and remote control applications. This emitter supports high pulse current operation and is spectrally matched to silicon photodetectors.

Why Choose This Part

The TSAL6200 offers a narrow 34-degree viewing angle for focused radiant intensity of 40mW/sr at 100mA. Its low forward voltage of 1.35V and ability to handle high peak currents make it highly efficient for battery-powered pulse-modulated applications.

Applications

Infrared Remote Controls
High-power emission for television, audio, and air conditioning remote control units.
Optical Counters
Used as a reliable IR source for industrial counting systems and optical encoders.
Free Air Transmission
Suitable for short-range wireless data links and wireless infrared audio systems.
Card Readers
Acts as the illumination source in magnetic or optical card sensing hardware.

Getting Started

To drive the TSAL6200, use a constant current driver circuit or a current-limiting resistor sized for the 100mA continuous forward current. For remote control applications, use a MOSFET or transistor to pulse the LED at common carrier frequencies like 38kHz. Ensure the cathode (shorter lead) is connected to the low side of the circuit.
