scope:

This specification covers the detail requirements for 500-watt peak pulse, power, silicon, transient voltage suppressor diodes. Three levels of product assurance are provided for each encapsulated device type as specified in MIL-S-19500, and two levels of product assurance for each unencapsulated device type die device type as specified in MIL-S-19500.

See figures 1, 2, 3, 4, and 5.

Maximum ratings are as shown in columns 4, 6, and 7 of table III herein and as follows:

P_R = 2.5 W (T_A = room ambient as defined in the general requirements of 4.5 of MIL-STD-750) (derate at 16.7 mW/°C for nonsurface mount devices) (10 mW/°C for surface mount devices) (see figures 3, 4, and 5).

P_PR = 500 W (see figure 7) at t_p = 1 ms.

I_FSM = 80 A(pk) at t_p = 8.33 ms (T_A = +25°C).

−55°C ≤ T_op≤ +175°C; −55°C ≤ T_STG ≤ +175°C (ambient).
