With a 30V drain-source rating and 3.8A continuous drain current rating, it is suited to controlling higher-power loads from a low-power control signal.Its low gate threshold voltage makes it logic-level compatible, so it can be driven directly from 3V–5V microcontrollers such as Arduino or ESP32 boards, or from a mechanical switch. The low on-resistance helps reduce losses when switching loads.The DMP3099L-7 is a surface-mount component for PCB assembly and integration into custom designs.Features:P-channel MOSFET: For power management and load-switching applicationsLogic-level compatible: Can be controlled from 3V–5V microcontrollersLow on-resistance: Helps minimise power loss while switchingLow gate threshold voltage: Suitable for low-power control signalsControl options: Can be driven by microcontrollers such as Arduino or ESP32, or by mechanical switchesSurface-mount design: Intended for PCB assemblySpecifications:FET Type: P-ChannelTechnology: MOSFET (Metal Oxide)Drain to Source Voltage (Vdss): 30VCurrent - Continuous Drain (Id) @ 25°C: 3.8A (Ta)Drive Voltage (Max Rds On, Min Rds On): 4.5V, 10VRds On (Max) @ Id, Vgs: 65mOhm @ 3.8A, 10VVgs(th) (Max) @ Id: 2.1V @ 250µAGate Charge (Qg) (Max) @ Vgs: 5.2 nC @ 4.5VVgs (Max): ±20VInput Capacitance (Ciss) (Max) @ Vds: 563pF @ 25VPower Dissipation (Max): 1.08W (Ta)Operating Temperature: -55°C ~ 150°C (TJ)Mounting Type: Surface MountMfg #: DMP3099L-7A handy part for custom PCB designs that need microcontroller-friendly P-channel switching. **Product Type:** MOSFET ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDEsYCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--359289052baa81b699810eba569039c8ca624da7/30225-MOSFET-P-CH-30V-3p5A-Feature.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDE8YCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--f792031f91a24fc356d3bab3d11345d40080474e/30225-MOSFET-P-CH-30V-3p5A-Front.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDFMYCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--0edb32861b9a96d93bfb1d7b4776304871938ff0/30225-MOSFET-P-CH-30V-3p5A-Back.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDFcYCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--a73c09e4e5f511d2f11fdef356218a8eb1aaa197/30225-MOSFET-P-CH-30V-3p5A-Scale.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
