It provides reliable one-way voltage control for dynamic power selection and switchover, over-voltage protection, and designs that need a stable power input.The board breaks out four channels plus ground connections in a small 15.2mm x 12.7mm footprint. Ideal diodes help minimise forward voltage drop, internal power dissipation, and reverse DC leakage current compared with a standard diode arrangement.Supporting documentation includes the schematic, KiCad files, board dimensions, ideal diode characteristics, STEP file, and GitHub hardware repo.Features:Hot-swap support: Helps keep projects powered during power supply changes.Four channels: Includes four ideal diode channels.Ground connections: Ground connections are broken out on the board.One-way voltage control: Provides reliable one-way voltage control.Efficient power delivery: Minimises forward voltage drop and internal power dissipation.Low leakage: Minimises reverse DC leakage current.Power selection: Suitable for dynamic power selection and switchover.Protection use: Suitable for over-voltage protection projects.Specifications:Board Measurements: 15.2mm x 12.7mmTypical Forward Voltage Drop: 8mV (I=0.1A, VIN=20V)Typical Forward Voltage Drop: 12mV (I=0.1A, VIN=5V)Typical Forward Voltage Drop: 26mV (I=0.1A, VIN=1.8V)Typical Forward Voltage Drop: 62mV (I=1A, VIN=20V)Typical Forward Voltage Drop: 79mV (I=1A, VIN=5V)Typical Forward Voltage Drop: 120mV (I=1A, VIN=1.8V)Typical Forward Voltage Drop: 275mV (I=4A, VIN=20V)Typical Forward Voltage Drop: 350mV (I=4A, VIN=5V)Typical Forward Voltage Drop: 350mV (I=4A, VIN=1.8V)Typical On Resistance: 69mΩ (VIN=20V, I=4A)Typical On Resistance: 62mΩ (VIN=20V, I=1A)Typical On Resistance: 78mΩ (VIN=20V, I=0.1A)Typical On Resistance: 88mΩ (VIN=5V, I=4A)Typical On Resistance: 79mΩ (VIN=5V, I=1A)Typical On Resistance: 120mΩ (VIN=5V, I=0.1A)Typical On Resistance: 160mΩ (VIN=1.8V, I=4A)Typical On Resistance: 120mΩ (VIN=1.8V, I=1A)Typical On Resistance: 260mΩ (VIN=1.8V, I=0.1A)Typical Reverse Leakage Current: -50μA (VIN=1.8V, V_fwd=-1V)Typical Reverse Leakage Current: -190μA (VIN=1.8V, V_fwd=-8V)Typical Reverse Leakage Current: -110μA (VIN=5V, V_fwd=-1V)Typical Reverse Leakage Current: -260μA (VIN=5V, V_fwd=-8V)Typical Reverse Leakage Current: -420μA (VIN=20V, V_fwd=-1V)Typical Reverse Leakage Current: -560μA (VIN=20V, V_fwd=-8V)A handy power-path building block for projects that need efficient source selection, reverse blocking, or cleaner supply switchover behaviour. **Product Type:** Power Management Breakout ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDLEYBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--343167ac96dfc2f8e85b3541016aee502e9a4781/27925-ideal-diode-breakout-feature.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDLUYBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--aeb817b6115b52c33726294a04c5079931926c5d/27925-ideal-diode-breakout-front.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDLkYBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--540d6ef9f228ac91d0282e0ffdc5c58d39f6b451/27925-ideal-diode-breakout-back.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDL0YBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--8a257a3d7fa06569c53f0c82aec592e01445dec0/27925-ideal-diode-breakout-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).
