Product details

Overview

TSOP4836DI1 from Vishay Semiconductors is a 36 kHz infrared (IR) receiver module optimized for long-burst remote control systems, featuring AGC4 configuration for enhanced noise immunity against fluorescent lamps, LCD TV emissions, and Wi-Fi interference, with supply voltage range 2.0–5.5 V and typical supply current of 0.35 mA at 3.3 V.

For engineers reviewing the TSOP4836DI1 datasheet, TSOP4836DI1 pinout, TSOP4836DI1 application, or TSOP4836DI1 equivalent, this device is selected for RC-5, RC-6, Panasonic, and Mitsubishi IR protocols in consumer remote control designs requiring high ambient-light rejection and reliable demodulated output directly interfaced to microcontrollers.

Technical Context

The TSOP4836DI1 integrates a PIN photodiode and preamplifier on a lead-frame substrate within an epoxy package containing an integrated IR bandpass filter centered at 950 nm. Its internal AGC4 circuit dynamically adjusts gain to suppress spurious outputs from continuous or modulated ambient IR sources while preserving sensitivity to valid 36 kHz carrier bursts.

It implements a band-pass filter with Δf(3 dB) = f₀/10 (i.e., ±3.6 kHz bandwidth), supports minimum burst length of 10 cycles, requires ≥12-cycle gap between bursts, and delivers active-low demodulated output compatible with standard CMOS/TTL logic inputs without external level-shifting.

Key Specifications

Parameter	Value and Actual Design Meaning
Carrier frequency	36 kHz - precisely tuned for Panasonic and Mitsubishi IR protocols; ensures optimal signal-to-noise ratio when paired with matching emitter diodes like TSAL6200.
Supply voltage	2.0 V to 5.5 V - enables direct interface with 3.3 V and 5 V microcontrollers without external regulators or level shifters.
Supply current (typ.)	0.35 mA at 3.3 V - enables ultra-low-power operation suitable for battery-powered remotes with multi-year shelf life.
Output polarity	Active-low - provides direct compatibility with standard MCU GPIO interrupt inputs configured for falling-edge detection.
Minimum irradiance (NEC)	0.08 mW/m² - ensures reliable reception under low-signal conditions such as oblique angles or extended distances up to 39 m with TSAL6200 emitter.
Directivity (±45°)	Half-angle transmission distance - defines usable horizontal field-of-view for ergonomic remote pointing without precise aiming.
Operating temperature	−25 °C to +85 °C - supports deployment in consumer electronics operating across indoor residential and commercial environments.

Pinout & Package

TSOP4836DI1 uses the TSOP348.. package: molded epoxy, leaded, dimensions 6.0 mm × 6.95 mm × 5.6 mm, with 3-pin inline configuration and marking area on top surface.

Pin/Terminal	Circuit Role	Design Meaning
1	OUT	Demodulated active-low output signal - directly drives MCU GPIO; requires no pull-up if MCU input has internal weak pull-up or is configured for open-drain mode.
2	GND	Analog ground reference for internal amplifier and AGC circuit - must be connected to clean system ground plane to maintain noise immunity.
3	VS	Positive supply input - decoupling capacitor (e.g., 10 µF tantalum + 100 nF ceramic) recommended near pin per application circuit guidance.

Key Features

Feature	Design Value
AGC4 configuration	Optimized for long-burst codes (RC-5, RC-6, Panasonic); provides higher noise suppression than AGC2 at cost of reduced compatibility with short-burst formats.
Integrated IR filter	Blocks visible and near-IR ambient light (e.g., sunlight, incandescent, LED lighting) while transmitting 950 nm signal - eliminates need for external optical filtering.
High ambient immunity	Suppresses interference from fluorescent lamps (both low- and high-modulation types), LCD TV backlight leakage, and Wi-Fi RF harmonics via adaptive gain control and envelope detection.
Low supply current	0.25–0.45 mA typical - reduces thermal load and extends battery life in portable IR remotes without compromising sensitivity.
Direct microcontroller interface	CMOS/TTL-compatible active-low output - eliminates need for external inverters or signal conditioning circuits in most embedded designs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar IR receiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSOP34436	Different pinout: Pin 1 = OUT, Pin 2 = GND, Pin 3 = VS - same AGC4 configuration and 36 kHz tuning, but incompatible PCB layout due to swapped VS/GND.	Designed for same long-burst protocols (Panasonic, Mitsubishi), but requires board revision for pin mapping.	Select TSOP34436 only when redesigning for TSOP344.. footprint; TSOP4836DI1 maintains legacy TSOP348.. layout compatibility.
TSOP32236	TSOP322.. package: Pin 1 = OUT, Pin 2 = VS, Pin 3 = GND; identical electrical specs but different mechanical mounting and thermal profile.	Same protocol support, but lower thermal mass and different soldering profile - not drop-in for through-hole TSOP348.. sockets.	Choose TSOP32236 for space-constrained PCBs where TSOP322.. footprint is already allocated; TSOP4836DI1 suits standard TSOP348.. assembly lines.

Compared with TSOP34436 and TSOP32236, TSOP4836DI1 offers direct compatibility with existing TSOP348.. layouts and tooling, preserves mechanical robustness for wave-soldered consumer assemblies, and avoids requalification of thermal and ESD performance in production.

FAQ

What is the carrier frequency supported by TSOP4836DI1?

The TSOP4836DI1 is factory-tuned to 36 kHz, making it ideal for Panasonic and Mitsubishi IR remote control protocols. This frequency is fixed and not adjustable; deviation beyond ±3.6 kHz (Δf at 3 dB) significantly degrades sensitivity. The device does not support multi-frequency operation or software reconfiguration - its center frequency is defined by internal filter design and cannot be modified in-circuit.

Does TSOP4836DI1 require external components for basic operation?

Yes - TSOP4836DI1 requires a 10 µF tantalum (or equivalent low-ESR) capacitor and a 100 nF ceramic capacitor placed as close as possible to the VS and GND pins to suppress supply ripple and prevent false triggering. No external resistors, pull-ups, or level shifters are needed for standard 3.3 V or 5 V MCU interfaces, as the active-low output is CMOS/TTL compatible per specification.

Is TSOP4836DI1 qualified for automotive applications?

No - TSOP4836DI1 is explicitly stated in the Vishay documentation as "not qualified to automotive specifications." It is rated for −25 °C to +85 °C operating temperature and lacks AEC-Q200 stress testing, PPAP documentation, or automotive-grade traceability. For automotive infotainment remotes, Vishay recommends evaluating the TFD series or contacting Vishay Automotive for qualified alternatives.

How does the AGC4 setting in TSOP4836DI1 differ from AGC2 variants?

AGC4 in TSOP4836DI1 provides stronger noise suppression against fluorescent lamps and LCD TV emissions compared to AGC2, but reduces compatibility with short-burst protocols like Sony SIRC. AGC4 enforces stricter burst-length validation (≥10 cycles) and tighter envelope duty cycle limits, making it optimal for RC-5, RC-6, and Panasonic codes - confirmed in the Parts Table and "Best choice for" column of the Vishay datasheet.

Can TSOP4836DI1 decode raw IR signals without a microcontroller?

No - TSOP4836DI1 outputs only demodulated, active-low digital pulses corresponding to the envelope of the 36 kHz carrier; it performs no protocol decoding, timing measurement, or data framing. Full decoding of RC-5, NEC, or Panasonic commands requires an external microcontroller or dedicated IR decoder IC that interprets pulse widths and gaps per the respective protocol specification.
