|---|---|---|---|---|
| FFF Compatibility | Identical 8-pin DFN/QFN package pinout with pins 1-3 as Source, pin 4 as Gate, and pins 5-8/exposed pad as Drain.Housed in a standard 5mm x 6mm Power 56 (PQFN8) package that matches the physical footprint dimensions of the original 8-VSONP.Features slightly lower continuous drain current rating (78A vs 100A) and slightly higher Rds(on) max (7.2 mOhm vs 6.4 mOhm). | Matches the exact standard pinout layout: pins 1-3 Source, pin 4 Gate, pins 5-8 Drain, and center pad Drain.Standard QFN 5mm x 6mm package is physically interchangeable with the original VSONP 5x6 package.Meets or exceeds all safety-critical parameters including 100V breakdown, 100A continuous current, and lower on-resistance. | ||
 AI Summary | CSD19531Q5A by Texas Instruments: N-Channel 100 V 100A (Tc) 3.3W (Ta), 125W (Tc) Surface Mount 8-VSONP (5x6). | An excellent general-purpose alternative from onsemi's PowerTrench line that offers identical physical dimensions and pin layouts. While it carries a slightly higher maximum on-resistance and a slightly lower continuous current rating, it compensates with significantly lower gate charge and input capacitance for improved high-speed switching efficiency. This makes it highly compatible for synchronous rectification or motor control applications.
| A highly robust alternative that matches the 100A current capacity of the original while offering a lower on-resistance of 5.0 mOhm. It features an outstanding power dissipation capability of 250W and operates in temperatures up to 175°C. This makes it an exceptionally safe and high-performance choice for thermally demanding designs.
