20 kV Diode Teardown

Teardown of a 20 kV 5 mA high voltage diode (2CL77) in a DO-312 package manufactured by GETAI Electronic Devices Co. Ltd. (广州市格泰电子器件有限) under the brand HGVT Semiconductor.


Since posting this video I measured the diode with a PSU at some currents:
15.5 V @ 1 mA (0.70 V/die) 
21.2 V @ 5 mA (0.96 V/die) 
24.8 V @ 10 mA (1.12 V/die)
