High-speed photodetectors with ± 35° angle half sensitivity

Date: 09/08/2013
Vishay Intertechnology has unveiled high-speed photodetectors in miniature gullwing, reverse gullwing, and side-view packages with wide-view dome lenses. Offered with or without daylight blocking filters, featuring a ± 35° angle of half sensitivity, and AEC-Q101-qualified, the VEMD2xx3(SL) PIN photodiodes have a typical output current of 10 µA and an extremely low dark current of 1 nA while the VEMT2xx3(SL) phototransistors have a typical output current of 2.7 mA. For applications requiring emitter-detector pairs, these new photo detectors have matching emitters in Vishay’s high-speed ± 25° and ± 28° VSMB2943xX01 series.

These photo detectors can be used as photo interrupters, detectors for optical switches, counters, encoders, position sensors, and for IR remote control and data transmission in automotive applications, infrared (IR) touch panels, light curtains and barriers, and metering systems. Offering black dome lenses and spectral bandwidth ranging from 750 nm to 1050 nm, devices with daylight blocking filters are responsive to infrared light, while suppressing ambient light to increase the signal-to-noise ratio. Clear epoxy devices without daylight blocking filters offer a broader wavelength range of 350 nm to 1120 nm and are sensitive to visible and near infrared radiation.

The VEMD2xx3(SL) and VEMT2xx3(SL) series devices feature compact 2.3 mm by 2.3 mm by 2.55 mm gullwing and reverse gullwing packages, and side-view packages measuring 2.3 mm by 2.55 mm by 2.3 mm. Each device consists of an adapted lens radius for a wide ± 35° angle of half sensitivity, resulting in typical photo currents of 10 µA for the photodiodes and 2.7 mA for the phototransistors at 1mW/cm2 and 950 nm.

The photodiodes and phototransistors offer operating and storage temperature ranges from -40 °C to +100 °C. With a moisture sensitivity level (MSL) of 2a, per J-STD-020, the VEMD2xx3(SL) and VEMT2xx3(SL) series provide a floor life of four weeks. Compatible with lead (Pb)-free reflow soldering, the devices are RoHS-compliant, halogen-free, and conform to Vishay “Green” standards.

Samples and production quantities of the new photodiodes and phototransistors are available now, with lead times of eight weeks for larger orders.
