Overview
The onsemi 1N5818RL is an axial lead Schottky barrier rectifier featuring a 30 V peak repetitive reverse voltage and a 1.0 A average rectified forward current rating. It utilizes chrome barrier metal and epitaxial construction for low power loss and high efficiency. The device operates within a junction temperature range of -65°C to +125°C and supports a non-repetitive peak surge current of 25 A. Packaged in the DO-41 (Case 59) format, it is supplied in tape and reel configurations.
Feature Summary
- Employs majority carrier conduction to achieve negligible switching losses and extremely fast switching speeds.
- Features an extremely low forward voltage drop to minimize conduction losses and maximize rectification efficiency.
- Constructed with oxide passivation and metal overlap contacts for robust reliability.
Applications
- Low-voltage, high-frequency inverters
- Free wheeling diodes in switching circuits
- Polarity protection applications
Procurement Notes
Verify that the specific ordering suffix matches the required packaging configuration, as the 'RL' designation indicates tape and reel supply. Confirm RoHS compliance status and Pb-Free markings against the latest manufacturer documentation before integration into production assemblies.
Selection Notes
Select this component for circuits requiring low forward voltage characteristics at moderate current levels. Ensure the operating ambient temperature allows for proper thermal derating based on the specified junction-to-ambient thermal resistance values provided in the datasheet.
Part Context
This part belongs to the 1N581x series of axial lead Schottky rectifiers manufactured by onsemi. The series includes variants with different reverse voltage ratings, specifically the 1N5817 (20 V), 1N5818 (30 V), and 1N5819 (40 V), all sharing identical current handling capabilities and package styles.
Replacement Considerations
Direct substitutes include the Vishay 1N5818-E3/73 and the generic 1N5818 from other manufacturers. Verify pinout compatibility and thermal resistance parameters when cross-referencing with alternative suppliers.
FAQ
What is the maximum non-repetitive peak surge current?
The maximum non-repetitive peak surge current is 25 A for one cycle under half-wave, single-phase 60 Hz conditions.
How is polarity indicated on the device?
Polarity is denoted by a cathode band on the component body.
