Description
The EHHD036A0F [HAMMERHEAD*] Series, eighth-brick, low-height power modules are isolated dc-dc converters which provide a
single, precisely regulated output voltage over an ultra-wide input voltage range of 18-75Vdc. The EHHD036A0F provides 3.3Vdc nominal
output voltage rated for 36Adc output current. The module incorporates GE’s vast heritage for reliability and quality, while also using the
latest in technology, and component and process standardization to achieve highly competitive cost. The open frame module
construction, available in through-hole packaging, enable designers to develop cost and space efficient solutions. The module achieves
typical full load efficiency greater than 90% at VIN=24Vdc and VIN=48Vdc. Standard features include remote On/Off, remote sense, output
voltage adjustment, overvoltage, overcurrent and overtemperature protection. An optional heat plate allows for external standard,
eighth-brick or quarter-brickheat sink attachment to achieve higher output current in high temperature applications.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only,
functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of
the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of
sophisticated power architectures. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum
safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 15
A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input
current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.
