In the rapidly evolving world of consumer electronics and IoT, the demand for reliable infrared (IR) communication components continues to grow. The TSOP6156TT from Vishay Semiconductor stands out as a premium 56 kHz IR receiver module, offering exceptional sensitivity (40 m range) and noise immunity for remote control systems. With its compact SMD-4 package, wide operating voltage (2.5–5.5 V), and low power consumption (700 µA), this module is ideal for smart home devices, automotive systems, and industrial automation. Read on to discover how the TSOP6156TT can enhance your design’s performance while reducing BOM costs.

The TSOP6156TT integrates a photo detector and preamplifier in a single SMD package, simplifying PCB design. Key specifications include:
| Parameter | Value | Source |
|---|---|---|
| Carrier Frequency | 56 kHz | Vishay Datasheet (Rev. 1.7, 2022) |
| Transmission Distance | 40 m (max) | |
| Viewing Angle | 50° | |
| Supply Voltage | 2.5–5.5 V | |
| Operating Current | 700 µA (typ) | |
| Output Current | 5 mA | |
| Temperature Range | -25°C to +85°C | |
| Package Dimensions | 7.2 × 5.3 × 4 mm |
Noise Immunity: Rejects interference from LEDs, Wi-Fi, and LCD backlights (per IEC 61000-4-3)
Low Power: 700 µA current extends battery life in portable devices
Wide Voltage Range: Compatible with 3.3 V and 5 V systems
RoHS Compliant: Meets environmental standards (Directive 2011/65/EU)
When choosing an IR receiver, consider these factors:
Carrier Frequency: Match the transmitter’s frequency (56 kHz for TSOP6156TT)
Voltage Compatibility: Verify against your system’s power supply
Viewing Angle: Wider angles (50° here) improve reception in movable devices
Package Size: SMD-4 saves space vs. through-hole alternatives
Smart TVs: Reliable signal decoding even near noisy LCD panels
Automotive: Keyless entry systems with 40 m range
Home Automation: HVAC and lighting control hubs
Industrial: Machinery remote controls with -25°C tolerance
According to MarketsandMarkets (2023), the IR receiver market will grow at 6.2% CAGR through 2028, driven by smart home adoption. The TSOP6156TT’s balance of cost and performance positions it well for:
Cost-sensitive mass-market devices
Applications requiring FCC/CE compliance
Designs needing <1 µA standby current (with external circuitry)
| Model | Frequency | Range | Voltage | Advantage |
|---|---|---|---|---|
| TSOP6156TT | 56 kHz | 40 m | 2.5–5.5 V | Best noise immunity |
| TSOP4838 | 38 kHz | 35 m | 2.5–5.5 V | Legacy compatibility |
| VSOP98338 | 38 kHz | 45 m | 2.0–5.5 V | Lower voltage |
≈14 ms (from signal detection to output stabilization), per Vishay’s test conditions.
No, the guaranteed operating range is 2.5–5.5 V. For 2.0 V systems, consider VSOP98338.
Built-in EMI filters reject >90% of 50–60 Hz light noise (e.g., from incandescent bulbs).
Active-low (pulls to ground when IR detected).
>100,000 hours at 25°C, based on MIL-HDBK-217F calculations.
Vishay’s roadmap indicates:
Higher-frequency variants (up to 120 kHz) for data transmission
Integration with Bluetooth/Wi-Fi coexistence circuits
Smaller packages (e.g., 3 × 3 mm) for wearables
The TSOP6156TT combines proven IR technology with modern noise-rejection capabilities, making it a versatile choice for next-gen remote controls. Its 40 m range and 50° viewing angle ensure reliable operation in diverse environments. For pricing or technical support, contact Vishay’s team at [email protected].
