FDC6420C Description

Short technical summary and product information.

The FDC6420C is a dual N and P-Channel MOSFET array manufactured by ON Semiconductor using advanced POWERTRENCH technology. It integrates two complementary MOSFETs in a single SuperSOT-6 package, significantly reducing board space compared to separate SO-8 or TSSOP-8 devices.

 

Electrical specifications include a drain-source voltage rating of 20V for the N-Channel and -20V for the P-Channel. The N-Channel MOSFET supports a continuous drain current of 3A with a maximum on-resistance of 70 mOhm at 4.5V gate drive, and 95 mOhm at 2.5V. The P-Channel MOSFET supports -2.2A continuous drain current with a maximum on-resistance of 125 mOhm at -4.5V and 190 mOhm at -2.5V. Both channels feature logic-level gate thresholds, enabling direct drive from low-voltage logic sources.

 

The device is housed in a thin SuperSOT-6 package (TSOT-23-6), which offers a low 1mm profile and a small footprint suitable for space-constrained applications. Power dissipation is rated at 0.7W on a minimum copper pad, and up to 0.96W with an optimized 0.125 in² pad. The operating junction temperature range spans -55°C to 150°C.
