Bay Linear Inspire the Linear Power 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.
