Study of Recovery Time of Diodes with power supply and 1 meter Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12269
Indian Lab Suppliers supplies the Study of Recovery Time of Diodes with power supply and 1 meter (Product ID: 12269) as part of its electronics engineering lab equipment range. It measures the reverse recovery time of diodes and how it changes with switching frequency and forward current.
Quick Answer
When a conducting diode is suddenly reverse biased, stored charge lets reverse current flow for a short time before the junction blocks; this is the reverse recovery time. The board carries seven diodes and a 65 mm rectangular DC meter for setting the switching current. A function generator drives the diode and the recovery interval is read on a 20 MHz CRO, repeated at different frequencies and currents. The meter range is given as 0-50 mA on a microammeter, and no built-in supply is listed, so please confirm the meter range and whether a power supply is included at quotation.
