Lifetime Test of Power Semiconductors
The lifetime of power semiconductors is ensured by meeting test standards like AQG 324 and AECQ-101. To qualify their DUT according to these requirements, engineers perform intermittent operational life (IOL) and power cycling tests where the DUTs are switched on and off continuously to thermally stress them at the chip-near joins. Test systems for these applications must meet the following requirements:
- Meeting test standards like AQG 324 and AECQ-101
- Achieving high throughput, high efficiency, and high measurement quality
- Tests are relevant for silicon-based as well as SiC and GaN power semiconductors
IOL and Power Cycling Test Systems
NI’s IOL and power-cycling test systems help engineers to perform these tests efficiently with high channel density and high flexibility in terms of DUT package dimensions, seamless monitoring, and low costs.
Intermittent Operational Life (IOL)
- Testing discretes with loads up to 150 A
- Up to 80 channels per system, 8 channels per drawer
- Monitoring parameter: Tc, Iload, Vload, VReverse (VF), Rth, Tvj (Tjmax – Tjmin)
- The test system is MIL-STD-750D compliant
Power Cycler
- Up to 12 measurement channels at two current paths; gate drive from -18 up to +20 V
- Load current of up to 1000 A, 30 V at PSU output
