A 4-line, 5V TVS diode in the same SOT-23-6L package, but with higher capacitance. Requires engineering review.
NUP4114HMR6T1G is a 4-line, 5V TVS protection diode from onsemi in a SOT-23-6L package, notable for its ultra-low 0.3pF capacitance for high-speed interfaces. Finding a substitute requires matching the package, line count, and especially the low capacitance.
Higher capacitance (e.g., 0.6pF vs 0.3pF) can impact high-speed signal integrity.
Multiple candidates exist in the same SOT-23-6L package.
Several manufacturers offer similar 4-line, 5V TVS diodes.
Direct replacement for NUP4114HMR6T1G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use a parametric alternative like USBLC6-4SC6-ES, but verify pinout and test for signal integrity issues due to higher capacitance.
Signal degradation due to higher capacitance in substitutes.
