BCF240T

BCF240T
HIGH EFFICIENCY HETEROJUNCTION POWER FET CHIP (.3 µm x 2400 µm)
The BeRex BCF240T is a GaAs Power MESFET whose nominal 0.3 micron gate length and 2400 micron gate
width make the product ideally suited to applications requiring high OIP3 linearity and low phase noise
while providing high-gain and medium power from DC to 26.5 GHz. This product is well suited for either
wideband or narrow-band applications. The BCF240T is produced using state of the art metallization and
devices from each wafer are screened to insure reliability. These chips utilize SI3N4 passivation for
increased reliability.

DIE ATTACH RECOMMENDATIONS:
BeRex recommends the “Eutectic” die attach using Au-Sn (80%-20%) pre-forms. The die attach station must have
accurate temperature control, and the operation should be performed with parts no hotter than 300°C for less
than 10 seconds. An inert forming gas (90% N2-10% H2) or clean, dry N2 should be used.
HANDLING PRECAUTIONS:
GaAs FETs are very sensitive to and may be damaged by Electrostatic Discharge (ESD). Therefore, proper ESD
precautions must be taken whenever you are handling these devices. It is critically important that all work
surfaces, and assembly equipment, as well as the operator be properly grounded when handling these devices to
prevent ESD damage.
STORAGE & SHIPPING:
BeRex’s standard chip device shipping package consists of an antistatic “Gel-Pak”, holding the chips, placed inside a
sealed antistatic and moisture barrier bag. This packaging is designed to provide a reasonable measure of
protection from both mechanical and ESD damage.
Chip devices should be stored in a clean, dry Nitrogen gas environment at room temperature until they are
required for assembly. Only open the shipping package or perform die assembly in a work area with a class 10,000
or better clean room environment to prevent contamination of the exposed devices.
CAUTION:
THIS PRODUCT CONTAINS GALLIUM ARSENIDE (GaAs) WHICH CAN BE HAZARDOUS TO THE HUMAN BODY AND THE
ENVIRONMENT. THEREFORE, IT MUST BE HANDLED WITH CARE AND IN ACCORDANCE WITH ALL GOVERNMENTAL
AND COMPANY REGULATIONS FOR THE SAFE HANDLING AND DISPOSAL OF HAZARDOUS WASTE. DO NOT BURN,
DESTROY, CUT, CRUSH OR CHEMICALLY DISSOLVE THE PRODUCT. DO NOT LICK THE PRODUCT OR IN ANY WAY
ALLOW IT TO ENTER THE MOUTH. EXCLUDE THE PRODUCT FROM GENERAL INDUSTRIAL WASTE OR GARBAGE AND
DISPOSE OF ONLY IN ACCORDANCE TO APPLICABLE LAWS AND/OR ORDINANCES.

APPLICATION OR USE OF ANY PRODUCT OR CIRCUIT DESCRIBED HEREIN.
LIFE SUPPORT POLICY
BEREX PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES WITHOUT
THE EXPRESS WRITTEN APPROVAL OF BEREX.
1. Life support devices or systems are devices or systems which (a) are intended for surgical implant into the body,
or (b) support or sustain life, or (c) whose failure to perform when properly used in accordance with instructions
for use provided in labeling, can be reasonably expected to result in significant injury to the user.
2. A critical component is any component of a life support device or system whose failure to perform can be
reasonably expected to cause the failure of the life support device or system, or to affect its safety or
effectiveness.
