TVS Diode Arrays Hit The Road

Littelfuse unveils two series of AEC-Q101-qualified TVS Diode Arrays (SPA Diodes). The AQHV and AQHV-C series provide very fast acting over-voltage protection for power interfaces, passenger charging interfaces, and well as LED lighting modules, and low speed I/Os.

 

The 200W discrete AQHV Series (unidirectional) and AQHV-C (bidirectional) protect sensitive equipment from damage due to electrostatic discharge (ESD) and other overvoltage transients. Both series can safely absorb repetitive ESD strikes above the maximum level required by international standards without performance degradation and safely dissipate up to 8A (for AQHV12) of induced surge current with very low clamping voltages.

New VNA technologies enable mmWave broadband testing to 220 GHz, helping researchers and engineers to overcome test challenges and simplify mmWave testing.

Application development in the mmWave frequencies is growing. Broadband testing over hundreds of GHz of bandwidth is subject to repeatability/accuracy deficits, and engineers demand solutions to help overcome challenges and simplify mmWave testing.

 

Typical applications for AQHV and AQHV-C Series TVS Diode Arrays include:

  • ESD protection for automotive electronics.
  • LED lighting modules.
  • Mobile/handheld devices.
  • CAN BUS (drive-by-wire).
  • LIN BUS. RS-232 and RS-485 interfaces.
  • General-purpose low-speed I/Os.
  • Portable instrumentation.

 

AQHV and AQHV-C Series features include:

  • ESD protection up to ±30kV and surge protection up to 8A helps equipment manufacturers comply with and exceed industry standards, extending equipment life and system uptime.
  • Low dynamic resistance provides up to 60 percent lower clamping voltages than alternative technologies, offering an ideal solution for protecting modern electronics filled with small-geometry ICs.
  • The silicon diodes used in their construction are capable of handling >1000 ESD strikes or surge transients without performance degradation in contrast with alternative technologies that have an inherent wear-out factor.
