new products
diagnostic equipment, medical monitoring devices, and
dental applications.
All of the new VMS series provide output voltage options
from 12 to 58 Vdc, feature wide universal input voltage
ranges from 80 to 264 Vac, and offer no-load power
consumption as low as 0.5 W. The 180 W to 550 W
models also carry an input to output isolation of 4200
Vac with leakage current ratings as low as 0.3 mA at
230 Vac. Operating temperatures range at full load from
-40 up to +50°C with forced air cooling, derating to 50%
load at +70°C. Additional features include protections
for over voltage, over current, and short circuit, power
factor correction, and a 12 Vdc/500 mA fan output.
These medical power supplies further meet EN 55011
Class B limits for conducted and radiated emissions and
achieve an MTBF of 3.37 million hours, calculated per
Telcordia SR-332 Issue 3.
The VMS series are available immediately with prices

Automotive-Grade Regulators from Diodes
Incorporated Deliver 5V, 8V, or 12V Outputs
and Tolerate 60V Battery Transients
The ZXTR2105FQ, ZXTR2108FQ and ZXTR2112FQ
regulator transistors announced by Diodes Incorporated
are qualified to AEC-Q101 standards for high reliability
and are product part approval process (PPAP)-capable.
Designed to deliver 5V, 8V, or 12V regulated outputs
from nominal battery supplies of 12V or 24V, these
regulator transistors are well-suited for powering
vehicle electronics. These devices can tolerate battery
voltage spikes up to 60V, making possible applications
that cannot use standard linear regulators.
By monolithically integrating a transistor, Zener diode,
and resistor into a SOT23 package, these regulator
transistors reduce component count, which minimizes
PCB area and increases system reliability by reducing
PCB interconnect. The ZXTR2105FQ is targeted at
applications that require a 5V ±5% regulated supply
from a 12V battery, e.g., for a stable MCU supply
within the required 4.7V to 5.3V supply range. The
ZXTR2112FQ is aimed at cars and trucks that have 24V
batteries but need a 12V ±10% supply for applications
such as the VCC supply for gate driver ICs. All these
regulator transistors deliver an output current up to
15mA.
The 60V maximum input rating of all these regulators
ensures sufficient headroom in the event of transient
over-voltage conditions, while their line and load
regulation safeguards continuous operation by ensuring
transient voltage drops cannot cause latch-up, further
contributing to system reliability.
The automotive-qualified ZXTR21xxFQ devices provide
a highly reliable and compact solution to common
voltage regulator requirements in vehicle electronics
and are priced at $0.15 in 10k quantities.
