4500 V/1500 A New Press Pack IEGT that Helps to Reduce the Size and Power Consumption for High-Voltage Converters

Product News 2024-04

The package photograph of 4500 V/1500 a new press pack IEGT that helps to reduce the size and power consumption for high-voltage converters.

Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched a press pack IEGT "ST1500GXH35A" with ratings of 4500 V/1500 A that employs newly developed trench-type IEGT[1] chips for use in high-voltage converters such as DC power transmission systems and industrial motor controllers.

The newly developed IEGT chips reduce collector-emitter saturation-voltage and improve shutdown tolerance, short-circuit tolerance and high-temperature tolerance.
Therefore, compared with the existing product[2], the collector-emitter saturation voltage (VCE(sat))[3] of the new ST1500GXH35A has been reduced by approximately 26 % from 3.4 V to 2.5 V (typical). In addition, the new product features wide RBSOA[4] by improving shutdown tolerance, and tests short-circuit tolerance at a measurement voltage of 3400 V[5].
Furthermore, the junction temperature rating (Tj) has been increased from 125 °C to 150 °C (maximum) by improving the high-temperature tolerance of the diode.

ST1500GXH35A helps to reduce the size and power consumption for high-voltage converters such as DC power transmissions, static VAR compensators, and industrial motor controllers.

Notes:
[1] IEGT: Injection Enhanced Gate Transistor
[2] Existing product: ST1500GXH26A
[3] VCE(sat) Conditions: VGE=15 V, IC=1500 A, Tj=125 °C
[4] RBSOA: Reverse-bias safe operating area
[5] Existing products has no short-circuit tolerance test

Applications

  • DC power transmissions
  • Static VAR compensators
  • Industrial motor controllers

Features

  • Low-collector-emitter saturation: VCE(sat)=2.6 V (typ.) (VGE=15 V, IC=1500 A, Tj=150 °C)
  • Expanded RBSOA (reinforced for 3400 V of test voltage) [6], tested short-circuit tolerance[5]
  • Maximum junction temperature rating: Tj (max)=150 °C

Note:
[6] Shutdown test voltage of the existing product is 3000 V
