Panasonic AQY210KS PhotoMOS Relay SMD SPST-NO 350 V

The Panasonic AQY210KS PhotoMOS Relay is a surface-mount, single-pole normally-open (SPST-NO) solid-state relay with a maximum load voltage of 350 V.

The relay uses a MOSFET output to switch low-level analogue signals, providing precise control for sensitive electronic circuits. It is supplied in a compact SOP-4 surface-mount (SMD) package with gull wing terminals, and it handles both AC and DC loads with a load current of 120 mA.

Key Features

• Short-circuit protection latch mechanism for enhanced safety and device longevity in demanding applications
• Extremely low off-state leakage current, helping to minimise power loss and signal interference in the off state
• 1500 Vrms input/output isolation voltage for electrical separation between control and load circuits
• Operating ambient temperature range of -40°C to +85°C

Applications

The relay is designed for professional and industrial electronic equipment. It is commonly specified for modem and telephone infrastructure, precision measuring and testing instruments, security system control panels, and industrial automation equipment.

Specifications

• On-state resistance: 35 ohm (max)
• Off-state leakage current: 1 µA (max)
• Forward current (If): 1.1 mA
• I/O capacitance: 0.8 pF (typical)
• Width: 3.3, Depth: 1.5, Height: 4.3 (units not specified)
• Weight: 1.3 g
