Nexperia USA Inc. NX6020CAKSX

Overview

NX6020CAKSX from Nexperia is a complementary N/P-channel Trench MOSFET in SOT363 (SC-88) package, rated for 60 V (N-ch) and −50 V (P-ch), with continuous drain currents of 170 mA and −160 mA respectively, and R_DS(on) values of 3 Ω (N-ch @ V_GS = 10 V) and 4.5 Ω (P-ch @ V_GS = −10 V); used in compact relay drivers and level-shifting circuits requiring dual-channel switching in space-constrained PCBs.

For engineers reviewing the NX6020CAKSX datasheet, NX6020CAKSX pinout, NX6020CAKSX application, or NX6020CAKSX equivalent, this device serves as a verified dual-channel discrete switch optimized for high-speed line driving, power supply converter control, and bidirectional signal translation where low gate charge (0.33 nC N-ch / 0.26 nC P-ch) and ESD protection are critical.

Technical Context

This dual MOSFET integrates independent N-channel (TR1) and P-channel (TR2) devices sharing a common SOT363 thermally enhanced footprint. Each channel features trench-gate architecture enabling fast switching (t_d(on) = 6 ns N-ch, t_d(off) = 48 ns P-ch) and low threshold voltages (V_GS(th) = 1.1–2.1 V N-ch, −1.1 to −2.1 V P-ch).

Thermal performance is defined by junction-to-ambient R_th(j-a) of 500 K/W (N-ch) and 390 K/W (P-ch) on standard FR4, with derating curves confirming stable operation up to T_j = 150 °C. Safe operating area (SOA) plots validate pulsed current capability (I_DM = ±680 mA) under short-duration conditions.

FAQ

What is the maximum continuous drain current for each channel at 100 °C ambient?

At T_amb = 100 °C, the N-channel supports 100 mA continuous drain current (V_GS = 10 V), and the P-channel supports −100 mA (V_GS = −10 V), per Table 5 limiting values. Derating is linear above 25 °C, with full-rated current only guaranteed at T_amb ≤ 25 °C on standard FR4 PCB with 1 cm² drain pad.

Can NX6020CAKSX be used in a high-side P-channel switch configuration?

Yes - Pin 4 (S2) is the P-channel source and must be connected to the positive supply rail; Pin 5 (G2) is driven negative relative to S2 to turn on. The −50 V V_DS rating and −1.6 V typical V_GS(th) enable reliable operation with 3.3 V or 5 V logic-level gate drive using a simple inverter or charge pump.

Is the SOT363 package lead-free and RoHS-compliant?

Yes - NX6020CAKSX is manufactured in a lead-free, halogen-free, RoHS-compliant SOT363 package per Nexperia's product compliance documentation (document ID: "NX6020CAKS v.2", January 2018). Terminal finish is matte tin (Sn) over nickel (Ni) on copper leadframe.

Does the device include body diode conduction capability in both channels?

Yes - both channels feature integrated source-drain diodes: N-channel V_SD = 0.7 V typ at 115 mA (forward), P-channel V_SD = −0.85 V typ at −115 mA. These diodes support freewheeling in inductive loads and are characterized in Table 10 (V_SD parameters) with temperature-dependent curves (Figs. 19 and 30).
