The MA4E2502 Family of Surmount Schottky diodes are recommended for use in microwave circuits through Ku band frequencies for lower power
applications such as mixers, sub-harmonic mixers,
detectors, and limiters. The HMIC construction
facilitates the direct replacement of more fragile
beam lead diodes with the corresponding Surmount diode, which can be connected to a hard or
soft substrate circuit with solder.
Case Style 1246
Description and Applications
The MA4E2502 SURMOUNTTM Series Diodes are
Silicon Low, Medium, and High Barrier Schottky
Devices fabricated with the patented Heterolithic
Microwave Integrated Circuit (HMIC) process.
HMIC circuits consist of Silicon pedestals which
form diodes or via conductors embedded in a glass
dielectric, which acts as the low dispersion, microstrip transmission medium. The combination of
silicon and glass allows HMIC devices to have excellent loss and power dissipation characteristics in
a low profile, reliable device.
The Surmount Schottky devices are excellent
choices for circuits requiring the small parasitics of
a beam lead device coupled with the superior mechanical performance of a chip. The Surmount
structure employs very low resistance silicon vias
to connect the Schottky contacts to the metalized
mounting pads on the bottom surface of the chip.
These devices are reliable, repeatable, and a lower
cost performance solution to conventional devices.
They have lower susceptibility to electrostatic discharge than conventional beam lead Schottky diodes.

The multilayer metallization employed in the fabrication of the Surmount Schottky junctions includes
a platinum diffusion barrier, which permits all devices to be subjected to a 16-hour non-operating
stabilization bake at 300°C.
The “0502” outline allows for Surface Mount placement and multi-functional polarity orientations.

1. Rt is the dynamic slope resistance where Rt = Rs + Rj, where Rj = 26 / Idc (Idc is in mA)
Handling
Die Bonding
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. The top surface of the die has a protective polyimide coating to
minimize damage.
Die attach for these devices is made simple
through the use of surface mount die attach technology. Mounting pads are conveniently located on
the bottom surface of these devices, and are opposite the active junction. The devices are well suited
for high temperature solder attachment onto hard
substrates. 80Au/20Sn and Sn63/Pb37 solders are
acceptable for usage. Die attach with Electrically
Conductive Silver Epoxy is Not Recommended.
The rugged construction of these Surmount devices allows the use of standard handling and die
attach techniques. It is important to note that industry standard electrostatic discharge (ESD) control is required at all times, due to the sensitive nature of Schottky junctions.
Bulk handling should insure that abrasion and mechanical shock are minimized.

For Hard substrates, we recommend utilizing a
vacuum tip and force of 60 to 100 grams applied
uniformly to the top surface of the device, using a
hot gas bonder with equal heat applied across the
bottom mounting pads of the device. When soldering to soft substrates, it is recommended to use a
lead-tin interface at the circuit board mounting
pads. Position the die so that its mounting pads
are aligned with the circuit board mounting pads.
Reflow the solder paste by applying equal heat to
the circuit at both die-mounting pads. The solder
joint must Not be made one at a time, creating unequal heat flow and thermal stress. Solder reflow
should Not be performed by causing heat to flow
through the top surface of the die. Since the HMIC
glass is transparent, the edges of the mounting
pads can be visually inspected through the die after
die attach is completed.

The MA4E2502L-1246 chip was evaluated in a detector circuit in which the Schottky diode terminates a
50 ohm transmission line on a duroid substrate. The chip was attached to the terminal of a 3.5mm
connector and the output voltage was measured through a bias tee on a voltmeter.
Matching was not attempted.
