NSR1020MW2T3G Schottky Barrier Diode | Ultra-Low Vf (0.24V) SOD-323 Surface-Mount Schottky for Avalon 1126 / 1246 Hashboard Repair and Discrete Buck / Boost Converter Designs
The NSR1020MW2T3G is a Schottky barrier diode in compact SOD-323 surface-mount package marked RE — the rectification workhorse on Avalon 1126 and Avalon 1246 hashboards. Drop-in replacement for failed Schottky diodes during hashboard repair, refurbishment, or production-line assembly.
Delivers ultra-low forward voltage of 0.24V (typical) at IF = 10 mAdc — exceptionally low Vf even for a Schottky, which is what makes this diode ideal for low-voltage / high-current paths where every millivolt of forward drop translates into avoidable I²R loss. High current capability in a compact SOD-323 footprint integrates cleanly into dense hashboard PCB layouts. Functions equally well as a blocking diode in charging applications or as part of a discrete buck / boost converter circuit.
Typical Use in Avalon Hashboard Repair
- Avalon 1126 / 1246 hashboard rebuild — Schottky failures in domain power rails.
- Discrete buck converter rectification — secondary-side rectification in step-down converters.
- Blocking diode — protecting downstream stages from reverse current.
- Production assembly — refurb shops needing bulk Schottky stock for Avalon line work.
- General low-Vf rectification — any low-voltage circuit needing minimal forward drop.

FAQ — NSR1020MW2T3G Schottky Diode
Q: Why 0.24V Vf matters in hashboard buck rectifiers?
A: ASIC hashboards run domains at ~0.3-0.8V Vcore with currents of 10-30A per chip. At those low voltages, every 100mV of rectifier drop is a significant percentage of total domain power. The NSR1020MW2T3G's 0.24V Vf at 10mA minimizes that loss vs standard Schottky (0.4-0.5V) or PN-junction (0.7V) diodes.
Q: Can I substitute another SOD-323 Schottky?
A: For functional equivalents, look for SOD-323 Schottky with similarly low Vf and matching current rating. Avoid generic substitutes — the silk marking "RE" identifies this exact part in the Avalon 1126 / 1246 BOM. For OEM-spec repair, stick with NSR1020MW2T3G.
Q: How do I test for a failed Schottky on Avalon hashboard?
A: Use multimeter diode mode. Healthy Schottky shows ~0.2-0.3V forward drop and infinite resistance reverse-biased. Failed Schottky shows short (0V both directions) or open (infinite both directions). Visible burn marks confirm catastrophic failure.
Q: Bulk pricing for Avalon repair shops?
A: Yes — email contact@lys-sz.com with your monthly Avalon hashboard rework volume for tier pricing on NSR1020MW2T3G by the reel.
