Renesas: Radiation Tolerant Plastic Products

The ISL71xxx family of products, radiation-tolerant plastic-package ICs, enable cost-effective solutions for short-duration low Earth orbit (LEO) mission profiles.

Intersil radiation-tolerant plastic products include:

One-time radiation and electrical characterization during development for:

  • Total ionizing dose (TID) up to 30krad (Si) at a dose rate of ≤10mrad/sec.
  • Single event effects (SEE) with a linear energy transfer (LET) up to 43MeV
  • Military temperature range of -55°C to +125°C.

Automotive AEC-Q100 “like” qualification

  • 2000 hours of burn-in
  • 500 Temperature Cycles 
  • Package moisture sensitivity testing 
  • Outgassing of molding compound tested to ASTM E 595 specification 
  • Small form factor surface mount plastic packages, typically with Nickle/Palladium/Gold (Ni/Pd/Au) lead finishes

Manufacturing

  • 25ºC electrical screening (w/ -55C to +125C guard banded limits)
  • No ongoing in-line quality monitors, i.e. burn-in
  • High-reliability materials: Lead frame (NiPdAg or NiPdAg-Au plated to mitigate tin whiskers), Bond wires (Gold only, not copper)
  • Enhanced products (EP) policy in terms of change control and controlled base line (assembly & testing)
