High Reliability Silicon Power Rectifier Technical Data Sheet

Category: Diodes, Electronics, Microsemi Corp

Overview

This datasheet provides technical specifications for the high reliability silicon power rectifiers designed by Microsemi, identified by part numbers IN1614, IN1615, IN1616, 1N4458, 1N4459 and their respective “R” versions. These devices are qualified per MIL-PRF-19500/162 and feature glass passivated die and glass to metal seal construction, ensuring durable and reliable performance in demanding applications. Suitable applications for such components include power supply systems and converters within fields that require high reliability standards.

Absolute Maximum Ratings

The datasheet lists the absolute maximum ratings for these rectifiers, detailing parameters such as peak repetitive reverse voltage (V_RRM) ranging from 200 to 1000 volts, average forward current at a case temperature of 150°C capped at 15A, and peak surge forward current for an 8.3ms half-sine wave at a case temperature of 150°C limited to 100A. Additionally, thermal resistance from junction to case is marked at 4.5°C/W, and the operational case temperature range spans from -65°C to +175°C. The same temperature range applies to the storage temperature limits.

Electrical Characteristics

The rectifiers’ primary electrical characteristics include a forward voltage (V_F) maximum of 1.5 volts when the forward current is at 15A and the case temperature is 25°C. The datasheet specifies the reverse current (I_R) parameters under different conditions, presenting a leakage current of 50µA at a case temperature of 25°C and 500µA when the temperature is escalated to 150°C across the range of rectifiers. These values of reverse current leakage are crucial for understanding power efficiency and standby power loss within their applications.

Product Package

The available package type for the rectifiers is DO-203AB (DO-4), which is a common and robust package style used for high power devices. Its design allows for efficient heat dissipation and easy mounting onto a heatsink or chassis.
