Vishay 38 kHz IR Receiver, TSOP4138, Through Hole 3-Pin Mold Package, 2.5-5.5 V Supply, ±45° Angle, 45 m Range

Vishay's TSOP4138 is a high-performance 38 kHz infrared (IR) receiver designed for remote control and infrared communication uses. Packaged in a through hole 3-pin molded enclosure, it supports efficient infrared signal detection with excellent sensitivity and a maximum transmission range of 45 meters.

This IR receiver incorporates a ±45° angle of half transmission distance ensuring broad angular coverage for reliable remote sensing. It operates with a carrier frequency centered at 38 kHz, making it suitable for common IR remote control protocols.

The TSOP4138 requires a low supply voltage range from 2.5 V to 5.5 V and draws a minimal supply current of only 900 μA, contributing to energy-efficient designs. It provides an output current of 5 mA, capable of driving input circuits directly or through simple amplification stages.

The compact dimensions are 6.95 mm height, 6 mm length, and 5.6 mm width packaged within a durable mold, facilitating easy integration on through-hole PCBs. It is specified to function effectively in a temperature range from -25 °C to 85 °C, enabling usage in varied environmental conditions.

Typical applications include IR code learners, repeaters, infrared light barriers, and proximity sensors in consumer electronics, industrial automation, and communication devices. The component complies with DIN standards ensuring consistent quality and compatibility with system-level requirements.

Carrier frequency of 38 kHz supports standard IR remote control signals. Long maximum transmission distance of 45 meters enhances operational range. Wide reception angle ±45° ensures reliable signal capture over broad directions.

Low supply voltage and current enable efficient power usage. Compact mold package simplifies PCB assembly and integration. Wide operating temperature range for diverse applications. Three-pin through-hole mount type for robust mechanical mounting.
