Overview
The SD5401CY is a quad N-channel lateral DMOS switch in a SOIC-14L package. It features four enhancement-mode MOSFETs with Zener input protection, rated for ±5-V analog signals. Key parameters include a maximum drain-source breakdown voltage of 10 V, a threshold voltage max of 1.5 V, and an on-resistance of 75 Ω at VGS = 5 V. The device exhibits ultra-low reverse capacitance (Crss) of 0.2 pF typical and turn-on times as fast as 1 ns.
Feature Summary
- Quad SPST Switch with Zener Input Protection
- Ultra-High Speed Switching
- Low Interelectrode Capacitance and Leakage
- Single Supply Operation
Applications
- Fast Analog Switch
- Fast Sample-and-Holds
- Pixel-Rate Switching
- Video Switch
- Multiplexer
Procurement Notes
Verify the specific ordering suffix to confirm the package type matches the required SOIC-14L configuration. Ensure the component meets RoHS compliance standards if applicable to your manufacturing process. Confirm that the ±5-V signal rating aligns with your system's voltage requirements before procurement.
Selection Notes
Select this component when low insertion loss and high-speed switching are critical for analog signal routing. The low turn-on threshold simplifies driver requirements for TTL and CMOS logic. Consider the ±5-V limit carefully; use the SD5400 series if higher voltage handling up to ±10 V is necessary.
Part Context
This part belongs to the SD5000/5400 series of monolithic switches built on a proprietary DMOS process. The lateral construction minimizes capacitance and crosstalk. While similar to the SD5400, the SD5401 variant is specifically optimized for lower voltage applications, distinguishing it within the broader family of high-frequency RF switches.
Replacement Considerations
For TO-206AF or TO-253 packages, consider the SD211DE/SST211 series. Verify pinout compatibility and electrical ratings against existing designs when substituting.
