Product Overview
The IRM-3638T is a compact high-performance IR remote receiver from Everlight. It integrates PIN photodiode, AGC circuit, pre-amplifier, demodulator and band-pass filter in one single through-hole SIP-3 package, operating at standard 38kHz carrier frequency. It effectively filters sunlight and ambient light interference, outputs demodulated low-level logic signal directly compatible with MCU without extra peripheral circuits. Built-in metal shielding prevents EMI interference, delivering stable, low-power wireless remote control solution for consumer appliances.
Core Advantages
Total Optical Component Integration
Consolidates the photodiode, internal AGC amplification, and decoding filters into a single compact housing, preventing parasitic layout noise and lowering total component counts.
Exceptional Ambient Light Immunity
Equipped with sophisticated internal band-pass filtering and automatic gain thresholding that isolates the 38 kHz carrier waveform, preventing accidental triggers from sunlight or fluorescent lamps.
TTL and CMOS Direct Compatibility
Natively delivers an active-low demodulated logic output that interfaces seamlessly with standard 3.3V and 5V microcontrollers, bypassing the need for analog-to-digital level conversion.
Robust Internal Electromagnetic Shielding
Features an optimized internal metal lead-frame structure that blocks external EMI/RFI noise sources, ensuring clean signal integrity in dense consumer electronic layouts.

Frequently Asked Questions
Q1: Is your stock IRM-3638T 100% original genuine?
A: All IRM-3638T in stock are brand-new original Everlight components. Every batch passes strict quality inspection and anti-static moisture-proof packaging to protect through-hole pins during delivery.
Q2: Why is 38kHz carrier frequency critical for this IR receiver?
A: Most consumer remote controllers transmit signals at 38kHz to distinguish data signals from constant ambient infrared noise such as sunlight and heat sources. The built-in band-pass filter only retains 38kHz pulses and filters out all irrelevant optical interference.
Q3: Can this module decode high-speed continuous IR communication protocols?
A: It supports mainstream burst remote protocols including NEC, RC5 and Sony format. It is not suitable for continuous high-bandwidth IR transmission, as the internal AGC needs blank intervals to adjust gain normally.
Q4: How to obtain PCB footprints or bulk customized quotation?
A: Fill in the quick inquiry form on this page, mark your order quantity and project demands. Our optoelectronics support team will send complete technical documents and customized price lists within 24 hours.
