G3VM-21LR is a MOS FET relay produced by OMRON. It has the characteristics of the smallest SSOP package in the world, the realization of low C×R=5pF·Ω new MOS FET relay, the load voltage 20V type, and the output terminal capacitance of 1pF (standard) with special emphasis on high frequency characteristics.
This document describes the Omron G3VM-21LR MOS FET relay, the world’s smallest SSOP‑package relay designed for low‑capacitance high‑frequency applications. It includes mechanical dimensions, mounting information, and a wiring diagram for surface‑mount installation.
Key electrical characteristics such as LED forward current, forward voltage, maximum load current, contact resistance, and operating temperature ranges are listed, along with recommended operating conditions to ensure reliable switching performance. This manual is written in Chinese.
| LED forward current (IF) | 50 mA |
|---|---|
| LED forward voltage (VF) | Typical 1.0 V, Max 1.3 V |
| On‑state resistance (R_on) | 5 mΩ – 8 mΩ |
| Inter‑terminal capacitance (C_oss) | 1 pF (standard) |
| Operating temperature range | -20 °C to +85 °C |
| Storage temperature range | -40 °C to +125 °C |
| Package type | SSOP |
| Mounting style | Surface mount |
It is recommended to operate the relay between –20 °C and +85 °C.
The LED forward voltage is typically 1.0 V and can be as high as 1.3 V.
It uses an SSOP (Super Small Outline Package) housing.
