NOTES:

1

Unless otherwise specified VIN=5V, VC=1.5V, BOOST=VIN+5V.

2

Guaranteed by design but not tested. Typical parameters are representative of actual device performance but are for reference only.

3

Industrial grade devices shall be tested to subgroup 1 unless otherwise specified.

4

Military grade devices ("H" and "K" suffix) shall be 100% tested to subgroups 1,2,3 and 4.

5

Subgroup 5 & 6 testing available on request.

6

Subgroup 1,4,7 TC =+25°C

Subgroup 2,5

TC =+125°C

Subgroup 3,6

TC =-55°C

7

Continuous operation at or above absolute maximum ratings may adversely effect the device performance and/or life cycle.

8

The absolute maximum current of 4.5A applies for duty cycles of 0.75 or lower.

De-rate linearly from 4.5A at D=0.75 to 3.375A at D=100.

9

The internal case temperature must not exceed 175°C under any conditions.

10

Pre and Post irradiation limits at 25°C, up to 100 Krad(Si) TID (Condition A) and 50 Krad(Si) TID (Condition D), are identical unless otherwise specified.

11

Internal solder reflow temperature is 180°C, do not exceed.

12

Reference DSCC SMD 5962R11234 for electrical specification for devices purchased as such.

13

MSK5059EDU does not use RAD HARD Die, Post Irradiation specifications are not applicable.
