AS1G

Overview

The AS1G is an ultra-fast recovery rectifier diode manufactured by Diodes Incorporated. It features glass passivated die construction for high reliability and efficiency in high-frequency applications. The device is designed with a surge overload rating capable of handling up to 30A peak current, ensuring robust performance under transient conditions. It offers high current capability suitable for general-purpose rectification in power supply circuits.

Feature Summary

Glass passivated die construction ensures long-term stability and protection against corrosion.
Ultra-fast recovery time minimizes switching losses and improves overall circuit efficiency.
High surge overload rating provides resilience against transient current spikes.

Applications

General-purpose rectification in AC/DC converters
Freewheeling diodes in DC/DC converters
Protection diodes in relay and solenoid circuits

Procurement Notes

Verify the specific suffix and package variant when ordering, as availability may vary by region. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as product specifications can evolve. Ensure the selected component matches the required voltage and current ratings for the target application before procurement.

Selection Notes

Select this component for applications requiring fast switching speeds and high surge tolerance. Evaluate the thermal management requirements based on the forward current and ambient temperature conditions. Compare the reverse leakage characteristics at maximum operating temperature against alternative devices to ensure compatibility with sensitive control circuitry.

Part Context

The AS1G belongs to the standard rectifier diode family from Diodes Incorporated, targeting cost-effective solutions for consumer electronics and industrial power supplies. It complements the company's broader portfolio of discrete semiconductors designed for high-volume manufacturing environments.

Replacement Considerations

Consult official substitution guides for equivalent ultra-fast recovery diodes with matching voltage and current ratings. Verify pinout compatibility and package dimensions to ensure direct replacement feasibility without PCB redesign.
