Handling Precautions for IGBTs

Insulated Gate Bipolar Transistors are susceptible to gate-

insulation damage by the electrostatic discharge of energy

through the devices. When handling these devices, care

should be exercised to assure that the static charge built in

the handler’s body capacitance is not discharged through

the device. With proper handling and application procedures,

however, IGBTs are currently being extensively used in

production by numerous equipment manufacturers in

military, industrial and consumer applications, with virtually

no damage problems due to electrostatic discharge. IGBTs

can be handled safely if the following basic precautions are

taken:

1. Prior to assembly into a circuit, all leads should be kept

shorted together either by the use of metal shorting

springs or by the insertion into conductive material such

as “ECCOSORBD™ LD26” or equivalent.

2. When devices are removed by hand from their carriers,

the hand being used should be grounded by any suitable

means - for example, with a metallic wristband.

3. Tips of soldering irons should be grounded.

4. Devices should never be inserted into or removed from

circuits with power on.

5. Gate Voltage Rating - Never exceed the gate-voltage rat-

ing of VGEM. Exceeding the rated VGE can result in per-

manent damage to the oxide layer in the gate region.

6. Gate Termination - The gates of these devices are es-

sentially capacitors. Circuits that leave the gate open-cir-

cuited or floating should be avoided. These conditions

can result in turn-on of the device due to voltage buildup

on the input capacitor due to leakage currents or pickup.

7. Gate Protection - These devices do not have an internal

monolithic Zener diode from gate to emitter. If gate pro-

tection is required an external Zener is recommended.

Operating Frequency Information

Operating frequency information for a typical device

(Figure 3) is presented as a guide for estimating device

performance for a specific application. Other typical

frequency vs collector current (ICE) plots are possible using

the information shown for a typical unit in Figures 5, 6, 7, 8, 9

and 11. The operating frequency plot (Figure 3) of a typical

device shows fMAX1 or fMAX2; whichever is smaller at each

point. The information is based on measurements of a

typical device and is bounded by the maximum rated

junction temperature.

fMAX1 is defined by fMAX1 = 0.05/(td(OFF)I+ td(ON)I).

Deadtime (the denominator) has been arbitrarily held to 10%

of the on-state time for a 50% duty factor. Other definitions

are possible. td(OFF)I and td(ON)I are defined in Figure 21.

Device turn-off delay can establish an additional frequency

limiting condition for an application other than TJM.

fMAX2 is defined by fMAX2 = (PD - PC)/(EOFF + EON2). The

allowable dissipation (PD) is defined by PD = (TJM - TC)/RθJC.

The sum of device switching and conduction losses must not

exceed PD. A 50% duty factor was used (Figure 3) and the

conduction losses (PC) are approximated by PC = (VCE x

ICE)/2.

EON2 and EOFF are defined in the switching waveforms

shown in Figure 21. EON2 is the integral of the

instantaneous power loss (ICE x VCE) during turn-on and

EOFF is the integral of the instantaneous power loss (ICE x

VCE) during turn-off. All tail losses are included in the

calculation for EOFF; i.e., the collector current equals zero

(ICE = 0).
