scope:

This specification covers the detail requirements for B type (standard polarity) and RB type (reverse polarity), 50 watt, silicon, voltage regulator diodes. Four levels of product assurance are provided for each device type as specified in MIL-S-19500.

See figure 1 (DO-5).

Maximum ratings are as shown in columns 3, 7, and 9 of table V herein and as follows:

Derate P_T = 50 W at T_C ≥ ±75°C at 0.5 W/°C above T_C ≥ ±75°C.

−65°C ≤ T_C ≤ 150°C; −65°C ≤ T_STG ≤ +175°C.

Primary electrical characteristics are as shown in columns 1, 8, 11, and 13 of table V herein, and as follows:

Thermal resistance (R_ΘJC) = 2.0°C/W maximum.
