Toshiba SSM3K329R,LF N-Channel Switching MOSFET 30V 3.5A SOT-23F Obsolete 5-Pack
$5.95
This listing is for a 5-pack of (5 pcs) genuine Toshiba SSM3K329R,LF silicon N-channel MOSFETs from original Mouser Electronics distributor-labeled stock. The SSM3K329R is a compact surface-mount switching device designed by Toshiba for high-speed switching and power-management switch applications.
The device is rated for a maximum drain-source voltage of 30V and continuous drain current of 3.5A and uses Toshiba's compact 3-pin SOT-23F surface-mount package. It is part of Toshiba's U-MOSIII generation and supports low-voltage gate drive down to 1.8V. Maximum drain-source on-resistance is specified at 126 mOhm with a 4V gate drive, 170 mOhm at 2.5V, and 289 mOhm at 1.8V. Typical total gate charge is approximately 1.5nC at VGS 4V. These characteristics make the device useful for switching, load-control, power-management, DC control, and compact electronic repair applications.
At this time the Toshiba SSM3K329R is an obsolete / end-of-life device. Toshiba currently identifies the part as EOL announced, so this original distributor stock is particularly useful for legacy equipment repair, maintaining older circuit designs, restoration work, and technician bench stock where the original Toshiba device is desired.
Historical Note: Toshiba traces its industrial roots to enterprises established in Japan beginning in 1875, eventually becoming one of Japan's major electrical and electronics manufacturers. The SSM3K329R entered commercial production in February 2010 as part of Toshiba's small low-on-resistance MOSFET family for high-speed switching and power-management applications. With the device now at end-of-life, genuine original distributor stock has increased relevance for servicing equipment and circuit designs that were originally engineered around this Toshiba MOSFET.
These devices came from an original Mouser Electronics distributor package and have been repackaged by RF Boneyard into a convenient 5-piece quantity for repair technicians, electronics restorers, experimenters, and service benches that need original Toshiba stock without purchasing factory-reel quantities.
