Panasonic’s new Low CxR PhotoMOS offer the smallest housings combined with the lowest on-resistance for maximum continuous load currents of up to 1A.
The new CxR10 PhotoMOS relays belong to the successful Low CxR series PhotoMOS, with an optimized, i.e. low, product of C and R.
Especially measurement applications require the smallest possible output capacitance C at the open contact and at the same time a low on-resistance R at the closed contact for high-frequency loads. Optimizing the capacitance and the resistance component in the transistors makes this possible.
The most advanced MOSFET technology makes it possible to combine a very low contact resistance of 0.18 Ohms (typical) with a low output capacitance of 37.5pF (typical) at the same time.
The new types are available in the well proven ultraminiature VSSOP and SSOP housing types. The vertical VSSOP housing type with its minimal space requirement of 1.8mm x 2.1mm is the smallest design currently available on the market.
Furthermore, the new CxR10 PhotoMOS have a very short response time (0.2ms typical), a high I/O isolation (max. 1.5kVAC for SSOP), and a very low leakage current (< nA). The maximum switching voltage is 30V for both types, AC and/or DC.
Particularly in the areas of IC and board testers, medical technology and multipoint recording, the new CxR10 PhotoMOS relays in the VSSOP and the SSOP housing open up unprecedented opportunities in circuit-board design.
