Why isn’t current through D2 0 in LTSPICE

ltspice

enter image description here

The current through d2 should b zero as it is reverse biased. Why dosen't ltspice software
show zero current?


If I am doing somethin wrong then kindly make correction and tell me what to do to get zero current in both D1 and D2?

without running your circuit to check, it is usual to expect leakage current in bipolar devices, and silicon diodes are p type and n type, hence the bipolar name. When one diode is reversed biased, impurities in the silicon structure allow a very small current to flow through the device. This current is very temperature sensitive. In a circuit such as this I would expect the reverse bias leakage current to be micro amps or less.
