Fact Sheet 079
High-quality glass-passivated diodes
(Implotec)
BYD33J competitor investigation
This publication offers a direct comparison between Philips
Semiconductors’ glass-passivated BYD33J diode family (based on
the company’s proprietary Implotec technology) and two major
competitor products. The comparison highlights major advantages
of the Philips technology, including high reliability and excellent
thermal performance with no tendency toward delamination at the lead-
package interfaces.

Guaranteed avalanche energy
absorption capability (E

Higher leakage current due to
passivation (typ. I

T

Poor stability although level of
instability is just acceptable
Lower capability to withstand reverse
energy (E

to destruction = 2 mJ)
Glass bead moulded in plastic or
passivated chip
Lower max operating temperature
(T

•
Excellent pressure contacts due to
Implotec technology
Not sensitive to moisture,
hermetically sealed — no rejects on
humidity tests
Fatigue free because coefficients of
expansion of all used parts are
matched
Excellent thermal-fatigue performance
— no rejects in fatigue tests
•
•
Low temperature soldering
construction
Sensitive to moisture, plastic is
hygroscopic, delamination after
moulding
Plastic coefficient of expansion does
not match with the other parts,
resulting in delamination
Often rejects, chip cracks due to
coefficients of expansion
•
•
Low temperature soldering
construction
Glass-plastic is still sensitive to
moisture
With glass-plastic, delaminations are
still seen
Better than just plastic but not as good
as glass Implotec

delamination
M3D119
The SOD81 Implotec package
The graphs below show the difference in performance between
Philips’ BYD33J and a competitor type. The comparison shows
reverse leakage current (I
R
) degradation during high-temperature
reverse-bias reliability testing. The delamination, shown in the picture,
leads to contamination across the junction resulting in severe
degradation of I
R
.
