Description

The B3520 series consists of enhancement-mode
MOSFETs designed for high speed low-glitch switching
in audio, video, and high-frequency wireless
applications. The CT3520 is optimized as a high speed
driver. With a source feedback resistor it can be uses as
a high speed LED Driver.

The B3520 series uses Bay Linear ULTRA REL DMOS
Process for reliability and robust performance.

These MOSFETs utilize lateral construction to achieve
low capacitance and ultra-fast switching speeds. An
integrated Zener diode provides ESD protection.

Features

• Low capacitance – 0.3pF typical
• Low threshold – <1.5V max
• Fast switching – ton<1ns
• CMOS and TTL Compatible Input
Application

• LED Drivers
• Level Shifting
• Switch Drivers
• VHF/UHF Amplifiers
