The ZMDC953TA is a silicon low voltage hyperabrupt varactor diode manufactured by Diodes Incorporated. It features a dual common cathode configuration with tightly controlled C-V characteristics, making it suitable for frequency control and filtering applications. The device is optimized for control voltages from 0.5V to 2.5V, ideal for 3V systems.
Key electrical specifications include a maximum reverse voltage of 12V, reverse breakdown voltage of 12V min at 10 µA, and a maximum reverse leakage current of 20 nA at 8V (typical 0.010 nA). The capacitance at 0.5V and 1 MHz is 45 pF minimum, and at 1.5V it is 37 pF nominal. The capacitance ratio (C0.5/C2.5) is a minimum of 2. The quality factor (Q) at 0.5V and 50 MHz is a minimum of 250. Forward current is limited to 100 mA.
The device is available in a surface mount SOT-323 package (also compatible with SC-70). It has a maximum power dissipation of 300 mW at 25°C ambient when mounted on SOT-323. The product is RoHS3 compliant and REACH unaffected, with MSL level 1 (unlimited).
Typical applications include VCXO and TCXO oscillators, wireless communications, pagers, mobile radio, and digital radio receivers. The part is also available as band-selected versions (FSD273) for DAB applications.
