Vishay launches TSOP15300 IR receiver series with a 30 kHz to 68 kHz modulation range

On 4 August 2026, Vishay Intertechnology (NYSE: VSH) announced the TSOP15300 series of infrared receiver modules, covering a modulation frequency range of 30 kHz to 68 kHz - wide enough to demodulate every major remote control code in a single component^[1].

The problem the series solves

Standard IR receivers are typically tuned to one center frequency, limiting compatibility and requiring multiple devices to cover different code sets. That forces designers to stock and place several variants on a board whenever a product needs to respond to more than one remote control protocol. The wide modulation frequency range of the TSOP15300 overcomes this limitation, reducing component counts to lower system costs and save board space.

Key specifications

In a 4-pin Heimdall package, the devices integrate a photodetector, preamplifier, and IR filter, support supply voltages from 2.0 V to 5.5 V, draw a typical current of 0.35 mA, and reach transmission distances of up to 18 m with a 50 mA emitter. The series is optimised for short burst codes and features a maximum irradiance of 0.2 mW/m² at 45 kHz.

Each receiver integrates a photodetector, preamplifier circuit, and IR filter within the 4-pin Heimdall package, and the demodulated output signal can be directly connected to a microprocessor.

Noise immunity and target applications

A recurring design challenge in consumer electronics is interference from ambient light sources and wireless radios sharing the same enclosure. TSOP15300 series receivers provide immunity against ripple noise and interference from common sources such as IR emissions in CFL lamps and LCD televisions, and RF emissions from onboard Wi-Fi antennas.

Target end-products include:

• Televisions and LCD displays
• Audio systems and soundbars
• Gaming consoles
• Set-top boxes (STB)
• Video projectors^[1]

The devices are RoHS-compliant, halogen-free, and Vishay Green.

Availability

Samples and production quantities of the TSOP15300 are available now, with lead times of six weeks, and customers can order both evaluation samples and volume quantities through existing sales channels and distributors.

The TSOP15300 series is worth watching as a signal of where Vishay sees demand in the consumer electronics supply chain. Universal remote control compatibility has become a baseline expectation in smart-home and streaming-device platforms, and a single-module solution that eliminates frequency-specific variants simplifies both BOM management and firmware. Whether the series gains traction in set-top box and projector designs - where multi-protocol IR is a common requirement - will be a practical test of how much component consolidation the market is ready to accept at this price tier.
