MA2S35700L

Overview

The MA2S357 is a silicon epitaxial planar variable capacitance diode designed for CATV tuners. It operates with a maximum reverse voltage of 34 V and a peak rating of 35 V, maintaining a junction temperature limit of 150 °C. At 1 MHz, the zero-bias capacitance reaches 58.0 pF, dropping to approximately 2.92 pF at 25 V reverse bias. The device achieves a capacitance ratio of 11.0 between 2 V and 25 V. Series resistance is specified at 0.54 Ω when capacitance is 9 pF at 470 MHz.

Feature Summary

• Large capacitance ratio for effective tuning range
• Small series resistance to minimize signal loss
