Overview
The Diodes Incorporated 1N4933G-T is a fast recovery glass passivated rectifier featuring a DO-41 case. It supports a peak repetitive reverse voltage of 50V and an average rectified output current of 1.0A at 75°C. The device exhibits a forward voltage of 1.2V at 1.0A, with a peak reverse current of 5.0μA at 25°C. It withstands a non-repetitive peak forward surge current of 30A for 8.3ms. Electrical characteristics include a reverse recovery time of 200ns and typical junction capacitance of 15pF. Operating and storage temperatures range from -65°C to +150°C.
Feature Summary
- Glass passivated die construction ensures stable electrical performance and low leakage current.
- Fast switching design enables high efficiency in rectification applications.
- High current capability combined with low forward voltage drop optimizes power handling.
Applications
- General-purpose rectification in electronic circuits
- Free-wheeling diode applications in inductive loads
- DC-AC conversion systems
Procurement Notes
Verify the specific ordering suffix matches the required packaging configuration. Confirm that the component meets applicable RoHS directives and environmental compliance standards for the intended deployment region. Ensure lead finish specifications align with soldering process requirements. Validate that thermal management strategies accommodate the specified junction-to-ambient thermal resistance during operation.
Selection Notes
Select this component when a 50V reverse voltage rating is sufficient for the circuit's peak inverse voltage requirements. Consider the 1.0A continuous current capacity and 30A surge rating for load conditions. Evaluate the 200ns reverse recovery time against switching frequency demands. Verify that the DO-41 through-hole package fits the board layout constraints.
Part Context
This part belongs to the 1N4933G through 1N4937G series of fast recovery rectifiers manufactured by Diodes Incorporated. The series shares identical physical dimensions and electrical characteristics except for the maximum repetitive reverse voltage ratings, which vary from 50V to 600V across the lineup.
Replacement Considerations
Cross-reference with other manufacturers' 1N4933 equivalents. Verify that substitute parts maintain the same DO-41 package, 50V rating, and 1.0A current capacity. Ensure compatibility with glass passivation technology if low leakage is critical.
FAQ
What is the maximum non-repetitive peak forward surge current?
The device can withstand a peak forward surge current of 30A for a duration of 8.3ms as a single half sine-wave superimposed on rated load.
How is the polarity indicated on the component?
Polarity is identified by a cathode band printed on the molded plastic case.
