Dionics-USA introduces rugged
"Combat-Ready" version of its Photovoltaic MOSFET-Driver
DIG-11-8-30-DD Photovoltaic (PV) Mosfet Driver reintroduced on 11/1/2017
Dionics-USA, the originator of the Photovoltaic (PV) MOSFET-Driver,
has just introduced its new “Combat-Ready” surface mount version, part number CR54SM.
Company president, Bernard Kravitz, explained that over recent years, high-reliability Military packages for
PV MOSFET-Drivers have grown “ever smaller, more fragile, and ever more costly.
Expensive but fragile doesn’t make sense.”, he pointed out.
Inspired by the words of Thomas Edison, “There’s a way to do it better - find it.”,
Kravitz explained, “We determined to find that better way.”
The result is the company’s new rugged surface-mount part, CR54SM – “Combat-Ready”, as he states.
“It even looks bullet-proof,” he jokes, “but we haven’t tested for that yet.”
Kravitz also points out that not only is the new part physically much stronger, but it is also dramatically less costly.
Kravitz concluded: “In this increasingly hostile world, we expect many new Military equipment designs to seriously consider
replacing the earlier fragile parts with the new ‘combat-ready’ CR54SM device.”
The lastest version of the DIG-11-8-30-DD has higher Voc than previous versions.
It is an alternative drop-in part for the DIG-21-8-30-DD / DIG-21-15-30-DD product lines.
This part is available in straight-leg (DIG-11-8-30-DD) and gull-wing (DIG-11-8-30-DD GW) versions.
Samples of the new improved DIG-11-8-30-DD are available now.

New Products 8A100-1 and 8A100-2 Dual High-Current
Photovoltaic Power Source
The 8A100-1 and 8A100-2 are dual high-current Photovoltaic Isolator (PVI) milli-watt power source.
These devices achieve the highest output current of any PVI on the market today
while providing a logic-level compatible output voltage.

MOS Capacitors reintroduced as of 9/1/2014
New versions of the C 616A and C 632A capacitors are being reintroduced this month.
They are slightly smaller than the earlier versions of the C
616 and C 632.
Die thickness is now 10mils and the capacitors are for epoxy die bond only.
It is otherwise identical to the earlier version of the C
616 and C 632.
** C 616A C 632A
New Product -- C 632A MOS Precision
The C632A SOIC chip-capacitor array is housed in an 8 pin SOIC
surface mount package that provides
user-adjustable capacitance values that range from as low as
1pF up to 63pF in 1pF increments.
This enables a multivalue MOS capacitor to be soldered directly to a pc board.
The final desired value is selected by making parallel
connections to the appropriate
1 pF, 2pF, 4pF, 8pF, 16pF
and 32pF leads.

DIG-1115-SM reintroduced as of 8/1/2014
A new version of the DIG-1115-SM is being reintroduced this month.
This is in response to requests for a lower LED Forward voltage on the DIG-2115-SM.
This new version will also have a changed Isc spec as compared to the previous version.
It is otherwise identical to the earlier version of the DIG-1115-SM.

About our patented active
dynamic discharge circuitry…..
ISO-gate microcircuits designated DIG-21-8-30-DD,
DIG-21-15-30-DD and DIG-22-8-30-DDx are
optically coupled floating power sources used primarily to
control power MOSFETS when electrical isolation between input
and output is required. The dynamic discharge circuitry
additionally causes rapid, active turn-off of the MOSFET when
power to the input LED is interrupted.
patented dynamic discharge feature (US Patent 4,931,656)
guarantees break before make in most solid state relay
switching applications. And, since the turn-off is active,
the DD series is particularly effective for application in
noisy environments such as motor controllers.
the development of the DD series, photovoltaic MOSFET drivers
(ISO-GATES) consisted simply of an LED light source optically
coupled to a photovoltaic diode array. Circuitry to discharge
the MOSFET gate capacitance was either a resistor sized to
compromise the turn-on/turn-off time or some elaborate
multi-component turn-off scheme.
All of the above devices are available in a
variety of packages including gull-wing or straight leg
plastic DIPs and ceramic military packaging.
