STG4210QTR Description

The STG4210QTR is a high-performance, single-pole single-throw normally open (SPST-NO) switch designed by STMicroelectronics. This device is ideal for applications requiring low on-state resistance and fast switching times. The STG4210QTR features a maximum on-state resistance (R_on) of 1.3Ω, ensuring minimal power loss and high efficiency in signal routing. With a leakage current (I_S(off)) of only 100nA, the switch maintains excellent isolation when in the off state, making it suitable for low-power applications.

The STG4210QTR operates within a supply voltage range of 1.65V to 4.3V, providing flexibility in various power supply configurations. Its channel-to-channel matching (ΔR_on) is as low as 10mΩ, ensuring consistent performance across multiple channels. The switch also boasts a fast switching time, with turn-on (T_on) and turn-off (T_off) times of 55ns and 30ns, respectively, making it suitable for high-speed signal switching applications.
