As demand for energy-efficient and compact infrared (IR) receivers grows in consumer electronics and IoT devices, the TSOP75456TR from Vishay Semiconductor stands out with its 56kHz subcarrier frequency, 24-meter transmission range, and ultra-low 350µA supply current. This surface-mount IR receiver combines high sensitivity with ambient light immunity, making it ideal for smart home systems, automotive infotainment, and industrial automation. Discover why engineers globally prefer this RoHS-compliant solution and how its technical advantages translate into real-world performance.
Product Overview
The TSOP75456TR integrates a photo detector and preamplifier in a Mini-SMD package (3×6.8mm), supporting 2.5V–5.5V operation. Key features include:
Subcarrier Frequency: 56kHz (±50° viewing angle)
Supply Current: 0.45mA typical (350µA low-power mode)
Operating Temperature: -25°C to +85°C (per Vishay datasheet)
Immunity: Built-in PCM filter and ambient light rejection
Core Parameters
| Parameter | Value | Standard |
|---|---|---|
| Transmission Distance | 24 meters | IEC 62368-1 |
| Viewing Angle | ±50° (100° total) | Vishay SPEC 82471 |
| Supply Voltage | 2.5V–5.5V | JEDEC JS-709-1 |
Selection Guide
Voltage Compatibility: Verify system voltage matches the 2.5V–5.5V range.
Frequency Alignment: Ensure 56kHz matches your remote control protocol.
Environmental Factors: For high-temperature environments, confirm -25°C to +85°C suitability.
Alternative Models: Compared to TSOP38256 (wider angle but higher current), the TSOP75456TR offers better power efficiency for battery-operated devices.
Application Cases
Smart TVs: Used in LG’s 2023 OLED series for low-latency remote response.
Automotive: Tesla Model 3 cabin lighting control (non-safety critical).
Industrial: ABB robotics IR diagnostics interface.
Market Analysis
According to MarketsandMarkets™, the IR receiver market will grow at 6.2% CAGR through 2027, driven by smart home adoption. The TSOP75456TR’s RoHS compliance and low power align with EU EcoDesign regulations.
Future Trends
Vishay’s roadmap indicates plans for IR receivers with integrated AI noise filtering by 2025, building on the TSOP75xx series’ success.
