VSSOP PhotoMOS - smallest package in its class Panasonic Electric Works Europe AG
The new housing's vertical design provides for miniscule dimensions of just L x W = 2.2mm x 2.1mm at a height of 2.9mm, following the trend of ever increasing miniaturization.
The new VSSOP PhotoMOS relays belong to the successful series of "Low CxR" PhotoMOS, an optimized product combining low Capacitance with low Resistance.
Especially measurement applications require the smallest possible output capacity C at the open contact combined with a low On resistance at the closed contact for high-frequency loads. Optimizing the capacitance and resistance in the transistors makes this possible. Hence the typical output capacity for AQY221R2T (T = VSSOP) is 14pF and the On resistance is a mere 0.8Ohm. Moreover, the new RF VSSOP CxR10 PhotoMOS has a short turn-on time (typical 0.1ms), a high I/O isolation voltage (200VAC) and a low off-state leakage current (typical 20pA). The maximum switching power is 40VAC/ 250mA.
Typical application areas can be found anywhere where there are strict requirements for reliability and lifetime, and where high mounting density is demanded.
Particularly in the areas of IC and board testers, medical technology and multipoint recording, the new PhotoMOS relays in VSSOP packages make advances in circuit-board design possible that were never before even dreamed of.
