Introduction of SNM2300S N-channel MOSFET
In DC-DC conversion, load switching, battery management, and portable device power supply applications, SOT-23 packaged small-signal MOSFETs are widely used solutions due to their small footprint, fast switching speed, and ease of PCB layout.
Semiware's SNM2300S N-channel MOSFET, in a standard SOT-23 package, is optimized for low-power power conversion and load switching applications and can serve as an alternative to the commonly available MCC, the SI2300S.

This article will provide a detailed comparison of the SNM2300S and SI2300S in terms of key parameters, electrical performance, and application scenarios.
Key Features of SNM2300S
- Compact SOT-23 package for easy PCB design and replacement applications
- 20V N-channel MOSFET solution suitable for a wide range of low-voltage switching circuits
- Low on-resistance (RDS(ON)) reduces conduction losses and improves efficiency
- Wide range of applications, including DC/DC converters, load switches, battery-powered devices, and portable electronics
SNM2300S vs SI2300S Key Parameter Comparison
| Parameter | Semiware SNM2300S | MCC SI2300S |
| Channel | N-Channel | N-Channel |
| Package | SOT-23 | SOT-23 |
| Drain-Source Voltage (VDS) | 20V | 20V |
| Gate-Source Voltage (VGS) | ±10V | ±12V |
| Continuous Drain Current (ID) | 4.5A | 4.3A |
| RDS(ON) @ VGS=4.5V | ≤40mΩ | ≤33mΩ |
| RDS(ON) @ VGS=2.5V | ≤60mΩ | ≤53mΩ |
| Pulsed Drain Current | 15A | 17.2A |
Why Can the SNM2300S be an Alternative to the SI2300S?
As shown in the table above,
- both the SNM2300S and SI2300S are 20V N-channel SOT-23 packaged small-signal MOSFETs, and they have a high degree of compatibility in key electrical parameters.
- Both products use a standard SOT-23 package, which simplifies the replacement design process.
Therefore, for consumer electronics, IoT devices, power management, and low-voltage switching applications using the SI2300S, the SNM2300S can be a reliable alternative.
➡️ For high-current continuous conduction, high-frequency high-speed switching, or high-reliability applications, engineers are advised to carefully compare the datasheet parameters and verify them through sample testing before replacement to ensure that the final application requirements are met.
