Overview
The Diodes Incorporated 1N5819-T is a Schottky barrier rectifier housed in the DO-41 plastic package. It features a peak repetitive reverse voltage of 40 V and an average rectified output current of 1.0 A at +90°C. The forward voltage drop is specified at 0.60 V for a 1.0 A current and 0.90 V for a 3.0 A current. Non-repetitive peak forward surge current reaches 25 A under standard conditions. The device operates within a temperature range of -65 to +125 °C.
Feature Summary
- Guard ring die construction provides transient protection capabilities
- Low power loss and high efficiency design
- High surge capability with low forward voltage drop
- Lead-free finish compliant with RoHS directives
Applications
- Low-voltage, high-frequency inverters
- Free wheeling diode circuits
- Polarity protection applications
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the component meets all applicable regulatory standards required for your target market. Ensure compatibility with existing thermal management systems given the operating temperature limits. Validate that the selected variant matches the exact electrical characteristics needed for the circuit design.
Selection Notes
Select this component when a low forward voltage drop is critical for system efficiency. Consider the 40 V reverse voltage rating to ensure adequate margin for the application's peak voltages. Evaluate the thermal resistance parameters if the device will operate near maximum temperature limits. Verify that the through-hole DO-41 package fits the available board space and mounting requirements.
Part Context
This part belongs to the 1N5817-1N5819 series of 1.0A Schottky barrier rectifiers manufactured by Diodes Incorporated. The series utilizes silicon technology and offers various reverse voltage ratings to suit different circuit requirements. The product line is designed for general-purpose rectification in power supply and conversion applications.
Replacement Considerations
Consult official datasheets for cross-reference information from other manufacturers. Verify that any substitute component matches the DO-41 package dimensions and pinout configuration. Ensure the replacement maintains equivalent or superior electrical ratings for voltage, current, and thermal performance.
