The SL80F40 is a Fast Recovery Diode
A varistor effectively bypasses all transient surge voltages and prevents them from reaching the devices' internal circuitry
MQ-7 Gas Sensor Module 30A Hyper Fast Soft Recovery Diode Input voltage DC 5V DigitalMQ 7 is used for sensing CO concentrations in the air. The MQ 7 can detect CO levels ranging from 10 to 500 parts per million. This sensor has high sensitivity and a fast response time. The output of the sensor is an analog resistance. The sensor works in temperatures ranging from 10 to 50C and consumes less than 150 mA at 5 V. Both digital and analog outputs are available on this module. The threshold level for digital output can be easily adjusted
