what is the safety EOS range

[王剑翰]

Part No. :AFT21S230SR3

Description :Recent,I recieved the case about AFT21S230SR3. After FSL analysis confirmed, they both have gross damage from an EOS event. For the result, customer advise me for the safety EOS range.

For the part, whether is there the safety EOS range? And what is the safety EOS range?

Thank you & Best regard

We do not have a fixed safe operation graph for our RF devices.  Rather, we have a set on max ratings that can never be exceeded.

From the dada sheet, page 2, table 1, here is the list of max ratings for that part.

Drain--Source Voltage VDSS                                                                                 -0.5, +65 Vdc

Gate--Source Voltage VGS                                                                                     -6.0, +10 Vdc

Operating Voltage VDD                                                                                          32, +0 Vdc

Storage Temperature Range Tstg                                                                            -65 to +150°C

Case Operating Temperature Range TC                                                                  -40 to +150°C

Operating Junction Temperature Range TJ                                                             -40 to +225°C

CW Operation @ TC = 25°C when DC current is fed through drain lead, pin 5    CW 161W    1,7 W/°C

    Derate above 25°C

CW Operation @ TC = 25°C when DC current is fed through pin 4 and pin 6      CW 104W    0,41W/°C

    Derate above 25°C

The junction temperate is calculated using the thermal resistance rating of the part, the operating condition and the flange temperature, which is controlled by the customer.
