Vishay sensor modules TSSP93038xx

Vishay Intertechnology introduces two new fixed-gain infrared (IR) sensor modules designed to lower costs and increase stability for outdoor sensor applications. Offering typical irradiance of 1.3 mW/m² in compact Minimold packages, the surface-mount TSSP93038DF1PZA and leaded TSSP93038SS1ZA provide robust operation in direct sunlight, while still providing enough sensitivity for light barrier applications. Designed to receive IR pulses from an emitter with a peak wavelength of 940 nm.

Key features

• Reduced sensitivity eliminates the need for extremely low emitter forward currents
• Controlled sensitivity allows them to operate in full sunlight without unwanted pulses
• Offering typical irradiance of 1.3 mW/m² in compact Minimold packages
• Increase stability for outdoor sensor applications

Additional features

• Detection threshold of 1.3 mW/m² makes the receiver robust even in direct sunlight
• No additional parts are needed to protect the receiver
• Sensitivity for light barriers of up to 10 m range with a standard TSAL6100 emitter at 100 mA forward current
• Longer ranges can be achieved when using a more focused emitter like the VSLY5940 or by increasing the emitter forward current
• Low supply voltage range from 2.0 V to 3.6 V, low supply current of 0.8 mA, and carrier frequency of 38 kHz

Applications

• For the consumer market:
  • Soap dispensers, toilet flush
  • Metering - water level sensors
  • Toys - drones, robots, and vicinity switches
