Product Description
Vishay TSOP31238 is a 38 kHz infrared (IR) receiver module designed primarily for remote control systems. Featuring a built-in PIN diode and preamplifier, this device is housed within a robust TSOP epoxy package that includes an infrared filter, ensuring excellent noise rejection and signal integrity.
The module operates with a supply voltage range from 2.5 V to 5.5 V and draws a low supply current of approximately 900 μA, making it highly efficient for battery-powered applications. Its 3-pin through-hole mount and compact package size of 12.5 mm height, 10 mm length, and 5.8 mm width facilitates straightforward integration into electronic designs.
Engineered to perform over a wide operating temperature range from -25°C to 85°C, the TSOP31238 maintains reliable reception within ±45° half-angle and can operate effectively up to a 45-meter transmission distance. The device produces an output current of 5 mA suitable for direct connection to microcontroller inputs for signal decoding.
This receiver adheres to JEDEC quality standards and offers an internal PCM filter to minimize the influence of ambient light. The TSOP31238 series, unlike the newer TSOP314 series, is compatible with older AGC2 technology, making it ideal for legacy product support.
Built-in photodiode and preamplifier ensure high sensitivity and low noise. Wide temperature operating range supports industrial and commercial applications. Compact through-hole package simplifies PCB layout and assembly.
Low power consumption suits battery-operated devices. Internal IR filter enhances immunity against ambient light interference. High output current enables direct microprocessor interfacing without additional stages. Compliant with JEDEC standards for enhanced reliability and quality.
Designed primarily for remote control of consumer electronics and automation systems.
Used extensively in industrial, commercial, and consumer infrared remote control applications, this component delivers consistent and reliable IR signal reception. Its compatibility with a broad voltage range and compact design make it versatile for many electronic control systems including audio-visual equipment, HVAC controls, and home automation interfaces.
