Important Notes
This data sheet contains only product-specific data. For a detailed description, must-
read application notes and common data that apply to the whole series, please refer to
the “Description and Application Manual for 1SD312F2 SCALE High-Voltage IGBT
Drivers”.
When applying SCALE plug-and-play drivers, please note that these drivers are
specifically adapted to a particular type of IGBT module. Therefore, the type
designation of SCALE plug-and-play drivers also includes the type designation of the
corresponding IGBT module.
These drivers are not valid for IGBT modules other
than those specified. Incorrect use may result in failure.

Footnotes to the key data
1)
Supply voltages higher than those specified can lead to the destruction of the driver and protection
circuits on the output side. The gate-emitter voltage tracks the supply voltage. (Not regulated by
the gate drive unit.) The recommended DC/DC power supply ISO3116I with high-voltage insulation
capability is a suitable separate unit.
Static power consumption of the gate driver.
If the specified power consumption of the gate driver is exceeded on average, this indicates an
overload of the gate driver and the external DC/DC power supply ISO3116I.
Under-voltage monitoring of supply voltage of the gate driver. For a voltage lower than this limit,
the power modules are switched off.
This limit is due to active clamping. Refer to the “Description and Application Manual for 1SD312F2
SCALE High-Voltage IGBT Drivers”.
Pulse width of the direct output of the gate drive unit. (Excluding the delay of the gate resistors.)
Duration of blocking the command input (keeping the gate driver and the IGBT in the off-state)
after fault detection, i.e. power supply under-voltage lock out, or – only in 2-level mode – short-
circuit detection. (For three/multilevel mode, turn-off under the short-circuit condition is managed
by the host controller.)
The gate current is limited by on-board gate resistors.
Refers to the direct output of the gate drive unit. (Excluding the delay of the gate resistors.)
Including the delay of external fiber-optic links. Measured from the turn-on transition at direct
output of the gate drive unit (excluding the delay of the gate resistors) to the transition of the
status signal at the optical receiver on the host controller side.
Application-specific self-heating of gate drivers and IGBT modules, especially at high switching
frequency, must be taken into account. The switching frequency is usually limited due to the
switching losses of the IGBT modules. Because CONCEPT cannot predict how the drivers will be
incorporated in the user’s application, no binding recommended value for self-heating and thus for
the maximum useable output power can be given. It is therefore recommended to check the gate
driver’s ambient temperature within the system.
Including the delay of external fiber-optic links. Measured from the transition of the turn-on or
turn-off command at the optical transmitter on the host controller side to the direct output of the
gate drive unit. (Excluding the delay of the gate resistors.)
Including the delay of external fiber-optic links. Measured from the transition of the turn-on or
turn-off command at the optical transmitter on the host controller side to the transition of the
acknowledge signal at the optical receiver on the host controller side.
The transceivers required at the host controller side are not supplied with the gate driver. It is
recommended to use the same types as used in the gate driver. For product information refer to
www.IGBT-Driver.com/go/fiberoptics
The connector and cable to the DC/DC power supply are not supplied with the gate driver, but via
FCI Inc. Recommended crimp contact housing: order code 65039-032; recommended crimp
contacts: 5 pcs, order code 48236-002. Refer to
www.IGBT-Driver.com/go/fci
The recommended transmitter current at the host controller is 30-35mA, suitable for plastic optic
fibers with a length of less than 2.5 meters. A higher current may increase jitter or delay at turn-
off.
The transmitter current at the gate driver is 30-35mA.
GND of the power supply is not at the same electrical potential as the auxiliary emitter terminal of
the IGBT. They should never be connected together.
