Product catalog summary
Overview
The Antiparallel TSC-AP-02020 is a GaAs Schottky diode designed for high-frequency applications, featuring a junction capacitance as low as 1fF, allowing for a cutoff frequency greater than 2THz. It is characterized by very low parasitic capacitance and ultra-low series resistance, making it suitable for high-performance applications.

Key Features
  • Junction capacitance: 1fF
  • Parasitic capacitance: < 9fF
  • Ultra-low series resistance
  • Airbridged anode contact for reduced parasitic effects
  • Fully passivated by SiN
  • Flip chip and beamlead geometry
  • Anode metallization optimized for reliability
  • MMIC backend process available
  • Gold stand-off platforms for ruggedness

Specifications
  • Ideality (N): 1.1 - 1.2
  • Junction Capacitance (Cj): 4 fF
  • Total Capacitance (Ct): 20 fF - 26 fF
  • Series Resistance (Rs): 8.5 ohms
  • Forward Voltage (VF): 0.7 V - 0.85 V at 1mA
  • Reverse Breakdown Voltage (VBr): -5 V at -5uA
  • Saturation Current (Is): 1e-14 A

Measurement Details
  • Ideality is calculated using a specific formula involving thermal voltage and current measurements.
  • Saturation current is measured at a specific voltage.
  • Reverse breakdown voltage is measured at a reverse bias current compliance of -5uA.
  • Forward voltage is measured at a forward current of 1mA.
  • Series resistance is calculated using a specific voltage and current measurement method.
  • Junction capacitance is calculated based on device area and fixed capacitance per unit area.
