Inhalt:
The efficiency of power modules is highest close to their power limits but to operate at these limits a precise power semiconductor die temperature control is essential. Historically, MELF-NTC’s are used but are limited in terms of contacting technology. A new lead free NTC chip (L860) offers established R=T characteristics (R100: 493 Ω) and can be used with sintering and Al-heavy wire bonding for operating temperatures up to 175 °C. Reliability of L860 was tested according to industrial and automotive standards (AEC-Q200). Additionally, mechanical tests are presented to study the strengths of the chip towards mechanical loads during heavy-wire bonding.
