{"title":"Ideal Diode Breakout","handle":"sparkfun-ideal-diode-breakout","url":"/products/sparkfun-ideal-diode-breakout","description":"Keep your project powered through power-supply hot swaps with this compact ideal diode breakout from SparkFun. 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.","vendor":"SparkFun","product_type":"Power Management Breakout","in_stock":true,"options":[],"variants":[{"id":15572,"title":"Default Title","sku":"SF-COM-27925","mpn":"COM-27925","price":11.3,"on_sale":false,"in_stock":true,"available_quantity":92}]}
