20L15T, 20L15TS is IRF's 20 Amp Schottky diode with ultra low forward voltage drop and optimized for OR-ing applications in parallel power supplies.
The 20L15T and 20L15TS are Schottky rectifier modules optimized for ultra‑low forward voltage drop, making them ideal for OR‑ing parallel power supplies, converters, reverse battery protection, and redundant power subsystems. The proprietary barrier technology enables reliable operation up to 125 °C junction temperature.
The bulletin lists major ratings, voltage and current limits, thermal‑mechanical data, package styles (TO‑220AC for 20L15T, D2Pak for 20L15TS), marking information, and ordering details. All specifications are subject to change without notice and are qualified for industrial‑level use.
| Maximum Forward Voltage Drop (typical) at 19 A, 25 °C | 0.41 V |
|---|---|
| Maximum Average Forward Current | 20 A (150 % duty cycle @ 85 °C) |
| Junction Temperature Range | -55 °C to 125 °C |
| Package Style (20L15T) | TO‑220AC |
The device can handle up to 20 A average forward current with a 150 % duty cycle at 85 °C.
The typical forward voltage drop is about 0.41 V under those conditions.
A minimum torque of 6 kg‑cm and a maximum of 12 kg‑cm is recommended for non‑lubricated threads.
