MA2S37400L

Overview

The MA2S37400L is a silicon epitaxial planar variable capacitance diode manufactured by Panasonic Electronic Components, designed for CATV tuner applications. It operates within a maximum reverse voltage of 34 V and a peak reverse voltage of 35 V. The device exhibits a typical zero-bias capacitance of 87 pF at 1 MHz, with a capacitance ratio of 15.0 between 2 V and 25 V bias voltages. Series resistance is specified at 0.9 Ω when capacitance is 9 pF at 470 MHz. The component is housed in an SS-Mini type package (SC-79) and supports junction temperatures up to 150 °C.

Feature Summary
