MOSFET Tester & IGBT Tester

MOSFETs / IGBTs Functional Tester

For Industrial PCBs / Medical PCBs / Automotive ECUs

High Quality Components - High Accuracy - Functional Test - Accurate - Handmade Tester

Test Techniques:
applying a very small current to Gate of the component. a small electrostatic field causes conduction between Collector / Emitter junction In case of IGBT & In case of MOSFET , Drain / Source junction
can used with all types and Diode protection Mosfets and IGBTs

Product Application:

This Test Equipment would typically be used for Functional Test and Repair of products utilizing Switch Mode (switching) Power Supplies, Inverters or Chopper circuits. Some product examples are 115/ 230V Power Inverters, UPS Battery backup units (Uninterruptible PSU), Inverter based Welders, and Plasma Cutters.

The switching circuits in these products characteristically use either IGBT's or MOSFET's. The choice of which component is used is governed by the switching speed, current capacity and breakdown voltage requirements of the design.

It is important to note that these components are typically N-channel devices that require a positive gate voltage. MOSFET's should be enhancement-mode devices (normally off). Depletion mode devices are less common in these products.

By pressing the Test button on the IGBT & MOSFET Tester you apply a very small current to the Gate of the component. The voltage associated with this causes an electrostatic field to be setup within the Gate junction of the component. This small field causes conduction to take place in the Collector / Emitter junction (in an IGBT) or Drain / Source junction (in a MOSFET). The status of the component is displayed on the Device Conduction LED.

IGBT's (Insulated Gate Bipolar Transistor)
