NCE Power
An upgrade with higher current and lower RDS(on), but requires review of gate drive due to higher gate charge.
Find and compare alternatives for the NCE0117K, a 100V 17A N-Channel MOSFET. This guide reviews potential upgrades and parametric alternatives, highlighting key differences in performance and packaging to aid in your selection.
Gate charge (Qg) mismatch in upgrades can impact timing and gate driver load.
Most candidates use the same TO-252-2L package, but cross-vendor options require footprint verification.
Candidates are from active production lines from NCE Power and ROHM.
No verified direct drop-in replacement has been identified. NCE0130KA and NCE0140KA are strong upgrade candidates from the same manufacturer and package family, but require engineering review.
Upgrade to NCE0130KA or NCE0140KA for better performance, provided the gate drive circuit can handle the increased gate charge (Qg).
The primary risk when substituting is a mismatch in gate charge (Qg), which can affect switching speed and efficiency. For downgrades, the lower current rating is a critical risk.

| Feature / factor | NCE0117K | NCE0130KA | NCE0140KA | NCE0115K | Compatibility / risk |
|---|---|---|---|---|---|
| Package | TO-252-2L | TO-252-2L | TO-252-2L | TO-252-2L | TO-252-2L — Same package family.; NCE0140KA: Same package family.; NCE0115K: Same package family. |
| Voltage | 100V | 100V | 100V | 100V | 100V — Drain-Source Voltage (VDS) matches.; NCE0140KA: Drain-Source Voltage (VDS) matches.; NCE0115K: Drain-Source Voltage (VDS) matches. |
| Current | 17A | 30A | 40A | 15A | 30A / 40A / 15A — Higher continuous drain current (ID).; NCE0140KA: Higher continuous drain current (ID).; NCE0115K: Lower continuous drain current (ID). |
| Resistance | 70mΩ | 32mΩ | 12mΩ | 75mΩ | 32mΩ / 12mΩ / 75mΩ — Lower RDS(on) improves efficiency.; NCE0140KA: Significantly lower RDS(on) improves efficiency.; NCE0115K: Slightly higher RDS(on). |
| Gate Charge | 30nC | 67.2nC | 94nC | 22.3nC | 67.2nC / 94nC / 22.3nC — Higher gate charge (Qg) may slow switching.; NCE0140KA: Much higher gate charge (Qg) may slow switching and require a stronger driver.; NCE0115K: Gate charge (Qg) is a close match. |
The best alternatives are NCE0130KA or NCE0140KA. They offer higher current handling and lower on-resistance, which can improve efficiency. However, you must verify your gate driver circuit can handle their higher gate charge (Qg).
