B2520/B2515
N-CHANNEL DMOS FET SWITCH
VIDEO TRANSISTOR
Series
Description
Features
The B2520 series consists of enhancement-mode
MOSFETs designed for high speed low-glitch switching
in audio, video, and high-frequency applications. The
B2520 is optimized as a +-7V Switch driver. The B2515
is optimized as an Analog Switch with a 20V Source to
Body breakdown and low Drain Leakage.

•
High Input to Output Isolation – 120dB typical
Low feed through and feedback transients
Low Inter-electrode Capacitances
25V Drain-to Source breakdown for B2520
The B2500 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.
