Description
This device is a silicon, glass PIN diode surmount
chip fabricated with MACOMs’ patented HMIC™
process. This device features two silicon pedestals
embedded in a low loss, low dispersion glass. The
diode is formed on the top of one pedestal and
connections to the backside of the device are
facilitated by making the pedestal sidewalls
electrically conductive. Selective backside
metallization is applied producing a surface mount
device. This vertical topology provides for
exceptional heat transfer. The topside is fully
encapsulated with silicon nitride and has an
additional polymer layer for scratch and impact
protection. These protective coatings prevent
damage to the junction and the anode air-bridge
during handling and assembly.
Applications
These packageless devices are suitable for
moderate incident power applications, ≤10 W/CW or
where the peak power is ≤52 W, pulse width is
≤1 μs, and duty cycle is ≤0.01%. Their low parasitic
inductance, 0.4 nH, and excellent RC constant,
make these devices a superior choice for higher
frequency switch elements when compared to their
plastic package counterparts.

Total capacitance (CT) is equivalent to the sum of junction capacitance (CJ) and parasitic capacitance (CPAR).
Series resistance (RS) is equivalent to the total diode resistance: RS = RJ (Junction Resistance) + RC (Ohmic Resistance).
RS and CT are measured on an HP4291A Impedance Analyzer with die mounted in an ODS-1134 package.
Theta (θ) is measured with the die mounted in an ODS-1134 package.

Attachment to a circuit board is made simple through the
use of surface mount technology. Mounting pads are
conveniently located on the bottom surface of these
devices and are removed from the active junction
locations. These devices are well suited for solder
attachment onto hard and soft substrates. The use of
80Au/20Sn, or RoHS compliant solders is recommended.
For applications where the average power is ~1 W,
conductive silver epoxy may also be used. Cure per
manufacturers recommended time and temperature.
Typically 1 hour at 150°C.
8. Exceeding these limits may cause permanent damage.
Handling Procedures
All semiconductor chips should be handled with care
to avoid damage or contamination from perspiration
and skin oils. The use of plastic tipped tweezers or
vacuum pickups is strongly recommended for
individual components. Bulk handling should insure
that abrasion and mechanical shock are minimized.
When soldering these devices to a hard substrate, hot gas
die bonding is preferred. A vacuum tip pick-up tool and a
force of 60 to100 grams applied to the top surface of the
device is recommended. When soldering to soft
substrates, such as Duroid, it is recommended to use a
soft solder at the circuit board to mounting pad interface.
Position the die so that its mounting pads are aligned with
the circuit board mounting pads. While applying a
downward force perpendicular to the top surface of the
die, apply heat near the circuit trace and diode mounting
pad. The solder connection to the two pads should not be
made one at a time as this will create unequal heat flow
and thermal stress to the part. Solder reflow should not be
performed by causing heat to flow through the top surface
of the die to the back. Since the HMIC glass is
transparent, the edges of the mounting pads can be
visually inspected through the die after attachment is
completed.
Typical re-flow profiles for Sn60/Pb40 and RoHS
compliant solders is provided in Application Note M538 ,
“Surface Mounting Instructions“ and can viewed @
www.macom.com .
