Philips Discrete Semiconductors Whisker Test Results Update

Philips fail criteria: Whiskerlength > 50µm

• Room temperature storage: 2 years. Please refer to the pictures attached. Test is continued.

• Storage at 55°C uncontrolled humidity: 2 years.

Please refer to the pictures attached. Test is stopped as storage at 55°C is not an acceleration test for whiskers.

• Storage at 55°C and 85% humidity: 2000h. Please refer to the pictures attached.
