15 AMP ULTRA FAST RECTIFIER IN SMALL HERMETIC PACKAGE

Category: Diodes, Electronics, International Rectifier

Summary

The datasheet provides detailed information about a series of ultra-fast rectifiers that offer enhanced performance features suitable for high-reliability applications. The rectifiers, identified by part numbers OMSOO1ST through OMSOO7ST, are notable for their small form factor, high switching speed, low thermal resistance, and durable, hermetically sealed packaging.

Key Features

The rectifiers boast several crucial features that make them attractive for demanding applications:

– Small Size: The compact design is ideal for efficient use of space.

– Very Low Forward Voltage: Enhanced electrical efficiency is provided.

– Very Fast Switching Time: With times ranging from 35 to 50 ns (nanoseconds), they can switch extremely quickly.

– Hermetic Isolated Package: Ensures the components are protected from environmental factors.

– High Surge Capability: Can handle significant surge currents effectively.

– Low Thermal Resistance: They are capable of operating with minimal thermal-related performance loss.

– MIL-S-19500 Screening: Available with screening levels TX, TXV, and S, meeting the military specifications for high-reliability applications.

Description

The datasheet describes a line of rectifiers designed for power switching frequencies above 100 kHz. These devices are positioned as replacements for older DO-4 and TO-3 packaging technologies. The reference to “Hi-Rel” indicates that the rectifiers are intended for high-reliability scenarios where small size and hermetic sealing are imperative.

Absolute Maximum Ratings

Essential performance ratings included are:

– Peak Inverse Voltage: 50 to 600 V.

– Maximum Average D.C. Output Current: 15 A.

– Non-Repetitive Sinusoidal Surge Current: 180 A for 8.3 ms.

– Operating and Storage Temperature Range: -55°C to +150°C, accommodating a broad range of thermal conditions.
