IGBT: Ic-Vge for Expander Test

Measures Ic-Vge transfer characteristics for IGBT devices with multiple Vce values.

Used with:

  • B1506A: IGBT DUT

  • B1505A: IGBT DUT, IV test type
- Available only if you choose the H51 or H71 Instrument option in the Hardware Configuration dialog.
- This test requires Ic-Vge PD1000A.xtdconfiguration file. See Install PD1000A Configuration Files for more information.

 

Set the test parameters based on the specifications in the device's data sheet:
- If the data sheet lists a maximum test limit for a parameter, use that value.
- If there is no maximum test limit, use a typical value.

Test Schematic

Gate Parameters

Gate: The SMU connected to Gate terminal, primary sweep voltage output. Select Gate SMU from the drop-down menu.

VgeStart (V): The Sweep start voltage for gate pulse bias.

VgeStop (V): The Sweep stop voltage for gate pulse bias.

VgeStep (V): The Sweep step voltage for gate pulse bias.

IgLimit (A): The Upper limit of gate current.

VgeBase (V): The Gate pulse baseline voltage.

VgeWidth (s): The Gate pulse width (in seconds).

VgeDelay (s): The Gate pulse delay time (in seconds).

Emitter: The GNDU:GND connected to Emitter terminal. This field cannot be changed.

Gate Resistance: Specify the desired Gate Resistance for the device, either 0 (default), 10, 100, or 1000 W.You must set the same Gate Resistance value in two places: 1) in the parameters for this test; and 2) in the EasyEXPERT software for your B1505A or B1506A power analyzer. See Additional IV and CV Test Information.

Collector Parameters

Collector: The SMU connected to Collector terminal, secondary sweep voltage output. In general, use the Input UHCU for this test.

VceStart (V): The Sweep start voltage for Collector terminal.

VceStop (V): The Sweep stop voltage for Collector terminal.

VceStep (V): The Sweep step voltage for Collector terminal.

IcLimit (A): The Upper limit of collector current.

VceBase (V): The Collector pulse base line voltage.

VceWidth (s): The Collector pulse width.

VceDelay (s): The Collector pulse delay time.

PulsePeriodMode (s): The Pulse period mode, AUTO or MANUAL.

ManualPulsePeriod (s): The Pulse period, effective if PulsePeriodMode = MANUAL.

MeasTime (s): The Actual measurement time for a pulse period.

PulseAvgCnt: The Pulse averaging count.
