High Reliability Power Rectifier Technical Data Sheet

Category: Diodes, Electronics, Microsemi Corp

Overview

This datasheet provides detailed technical specifications for the Microsemi High Reliability Power Rectifier series qualified per MIL-PRF-19500/260. The rectifiers feature a glass passivated die, glass to metal seal construction, and are capable of handling up to 25 amps surge rating with peak repetitive reverse voltage (V_RRM) ranging from 200 to 1000 volts.

Product Models Included

Devices: IN1124A, IN1126A, IN1128A, 1N3649, 1N3650
Levels: JAN, with “R” designated models representing reverse polarity versions: IN1124RA, IN1126RA, IN1128RA, 1N3649R, 1N3650R

Absolute Maximum Ratings

The datasheet specifies the absolute maximum ratings for the power rectifiers at a case temperature (T_c) of +25°C unless noted otherwise. These ratings include average forward current at T_c 150°C, peak surge forward current at 8.3ms half sinewave at T_c 150°C, and thermal resistance junction to case. Furthermore, the operating case temperature range is specified from 65°C to 150°C, and the storage temperature range from 65°C to 200°C. Packaging standard for these rectifiers is DO-20BAA (DO-4).

Electrical Characteristics

Electrical parameters are provided for an ambient temperature (T_A) of +25°C, including forward voltage at 10A for each model and reverse current for various voltage ratings both at 25°C and at an elevated temperature of 150°C. Maximum forward voltage drop is capped at 2.2 volts, and reverse current ranges from microampere to milliampere levels depending on the conditions. Moreover, a note regarding pulse tests indicates a pulse width of 300 microseconds and a duty cycle of 2%.

Graphical Data

Page 2 of the datasheet presents graphical data illustrating the typical forward and reverse characteristics of the rectifiers. Figure 1 shows the reverse voltage versus reverse current at different temperatures, and Figure 2 depicts the instantaneous forward voltage against forward current again at various temperatures. This data assists users in understanding the rectifier performance in real-world applications.
