ST's hi-rel- and aerospace-diode portfolio includes Schottky (1N58xx, STPSx) and bipolar rectifiers (1N66xx, BYXxx).
These devices offer very good performances within many applications and are available with a reverse voltage up to 200 V and a maximum forward current up to 40 A.
Housed in a variety of packages, including TO-254, SMD.5 and LCC2 (compatible with US D5-A/B), they have been qualified under the ESCC system.

New Generation of Power Diodes for Space
With enhanced electrical performance, extended product range and guaranteed radiation hardness, ST's new generation of high-reliability Schottky diodes and rectifiers are ideal for the design of robust space solutions and other applications working in harsh environments. Housed in a variety of hermetic packages, these radiation-hardened devices are all qualified under the ESCC system.
The 150 V, 60 A STPS60A150C and 150V, 80A STPS80A150C Power Schottky diodes housed in an SMD.5 package are SEB (Single Effect Burnout) Schottky rectifiers immune up to 60 MeV.Cm2/mg. Their through-hole counterpart, the 150 V, 40 A STPS40A150CHR, available in a TO-254AA package, is now ESCC qualified with the April 2020 release of the ESCC QPL (Qualified Part List).
Three ESCC-qualified fast recovery rectifiers support the need for 200 and 400 V diodes: up to 40 A with the STTH40200CHR in a TO-254AA package and up to 60 A with the STTH60200CHR and STTH60400HR in SMD1 packages.
All these products feature the best-in-class forward voltage drop (VF) at 125°C, at nominal current and at up to 3 other forward currents (IF) per diode, making it possible to take full advantage of the low VF, regardless of the actual current in the application. All Power Schottky diodes have a guaranteed maximum dV/dt of 10 kV/µs.
