1T405A - Variable Capacitance Diode

General Description

The 1T405A is a variable capacitance diode designed for electronic tuning of wide-band CATV tuners using a super-small-miniature flat package (SSVC).

High capacitance ratio (C25/C28) is improved to support guard band.

Key Features

  • Super-small-miniature flat package.
  • Low series resistance 0.85 Ω Max.
  • Large capacitance ratio 12.5 Typ. 1.03 Min.
  • Small leakage current 10 nA Max.
  • Capacitance deviation within 2 % M-290 (f=470 MHz) (C2/C25) (C25/C28) (VR=28 V) Absolute Maximum Ratings (Ta=25 °C).
  • Reverse voltage VR 34.
  • Operating temperature Topr.
  • 20 to +75.
  • Storage temperature Tstg.
  • 65 to +150 V °C °C.
