Vishay Intertechnology AEC-Q102 Qualified Linear Optocoupler Offers Faster Response Times, Higher Isolation Voltage and Transfer Gain Stability
November 23 2022 - 11:00AM
Vishay Intertechnology, Inc. (NYSE: VSH) today introduced the
industry’s first AEC-Q102 qualified linear optocoupler. Offering
industry-high isolation voltage of 5300 Vrms, the Vishay
Semiconductors VOA300 provides a response time that is five times
faster than competing devices while delivering increased transfer
gain stability of ± 0.005 %/°C typical and a single-ended output
for design flexibility.
The Automotive Grade device released today consists of an AIGaAs
infrared LED (IRLED) irradiating an isolated feedback diode and an
output PIN photodiode in a bifurcated arrangement. The VOA300’s
feedback photodiode captures a percentage of the LED’s flux and
generates a control signal that is used to servo the LED drive
current, while the output PIN photodiode produces an output signal
that’s linearly related to the servo optical flux created by the
LED. The time and temperature stability of the input-output coupler
is ensured by using matched PIN photodiodes that accurately track
the output flux of the LED.
The VOA300’s single-ended output can be directly connected to an
amplifier stage or an analog to digital converter. The optocoupler
is designed for galvanically isolated current and voltage
measurement in electric vehicles (EV), including on-board chargers
(OBC), traction inverters, and DC/DC converters. The device
provides reliable and fast data transfers at the rate of 1.4 MHz
for these applications, while its fast response time enables quick
detection of voltage and current ripples for battery cut-off
mechanisms (eFuses) that protect passengers and vehicles.
The linear optocoupler offers low input-output capacitance of 1
pF typical, high gain linearity of ± 0.25 %, and low power
consumption of < 15 mW. In addition, the device features an
operating temperature range up to +125 °C, making it suitable for
applications in harsh industrial environments. The optocoupler is
RoHS-compliant, halogen-free, and Vishay Green.
Samples and production quantities of the VOA300 are available
now, with lead times of 10 weeks.
