5. Absolute Maximum Ratings<br />
5.1 Electrical Maximum Ratings<br />
Mini DIP (SPM3) Application Note (2012-07-09)<br />
Turn-off Switching<br />
The IGBTs incorporated into the Mini DIP SPM have a 600V volt VCES rating. The 500V VPN(Surge) rating<br />
is obtained by subtracting the surge voltage (100V or less, generated by the Mini DIP SPM's internal stray<br />
inductances ) from VCES. Moreover, the 450V VPN rating is obtained by subtracting the surge voltage (50V or<br />
less, generated by the stray inductance between the Mini DIP SPM and the DC-link capacitor) from VPN(Surge).<br />
Short-circuit Operation<br />
In case of short-circuit turn-off, the 400V VPN(PROT) rating is obtained by subtracting the surge voltage<br />
(100V or less, generated by the stray inductance between the Mini DIP SPM and the DC-link capacitor) from<br />
VPN(Surge).<br />

The maximum allowable DC continuous IGBT collector current at<br />
Tc=25˚C.<br />
The maximum junction temperature rating of the power chips<br />
integrated within the Mini DIP SPM is 150˚C. However, to insure<br />
safe operation of the Mini DIP SPM, the average junction<br />
temperature should be limited to 125˚C Although IGBT and FRD<br />
chip will not be damaged right now at TJ = 150˚C, its power cycles<br />
come to be decreased.<br />
Under the conditions that Vcc=13.5 ~ 16.5V, non-repetitive, less<br />
than 2s.<br />
The maximum supply voltage for safe IGBT turn off under SC<br />
“Short Circuit” or OC “Over Current” condition. The power chip may<br />
be damaged if supply voltage exceeds this specification.<br />
