Phototransistors are compatible with lead-free reflow soldering.

Press Release Summary:

Including Models VEMT3700, VEMT3700F, and VEMT4700, VEMT Series phototransistors have 2 µsec rise and fall times and ±60° angle of half intensity. Compatible with lead-free reflow soldering processes according to JEDEC-STD-020D, devices feature optical/electrical/mechanical compatibility to serve as pin-to-pin and functional equivalents for TEMT series phototransistors. Units suit object/proximity sensing, optical switching, shaft encoding, data transmission, and touch key applications.

Original Press Release:

Vishay's Releases New VEMT Series of Silicon NPN Phototransistors in PLCC-2 Package That Is Compatible with Lead (Pb)-Free Soldering

Featuring 2µs Rise and Fall Times and ±60° Angle of Half Intensity, Devices are 100% Compatible with Current TEMT Series for Easy Replacement

MALVERN, PENNSYLVANIA - April 4, 2008 - Vishay Intertechnology, Inc. (NYSE: VSH) continues to broaden its optoelectronics portfolio with the release of a new series of wide-angle phototransistors in a PLCC-2 surface mount package that is compatible with lead (Pb)-free soldering. Devices in the VEMT series serve as pin-to-pin and functional equivalents for the current TEMT series of phototransistors, enabling simple and quick migration to meet lead (Pb)-free soldering requirements.

Vishay's current TEMT series of phototransistors are lead (Pb)-free PLCC-2 devices, but they require lead (Pb)-based solder. The new VEMT series of phototransistors feature the same specifications as the TEMT series devices, but are compatible with lead (Pb)-free reflow soldering processes according to JEDEC-STD-020D. Optical, electrical, and mechanical compatibility allow for easy replacement of the TEMT phototransistors.

The VEMT3700, VEMT3700F, and VEMT4700 are optimized for object sensing, optical switching, proximity sensing, shaft encoding, data transmission, thumb wheel sensors, and touch key applications in distribution products such as ATMs, coin machines, and vending machines; consumer products; and automotive, EMS, and industrial systems

Samples and production quantities of the new VEMT series of phototransistors are available now, with lead times of four to six weeks.Pricing for U.S. Delivery in 10,000-piece quantities is $0.27 per piece.
