Overview
The Diodes Incorporated 1N4936-T is a single-phase, fast recovery rectifier diode housed in a DO-41 plastic package. It features a peak repetitive reverse voltage of 400 V and an average rectified output current of 1.0 A at +75°C ambient temperature. The device exhibits a maximum forward voltage drop of 1.2 V at 1.0 A and a peak reverse current of 5 µA at rated DC blocking voltage. Its non-repetitive peak forward surge current rating is 30 A for an 8.3 ms half-sine wave. The component operates within a junction and storage temperature range of -65°C to +150°C.
Feature Summary
- Fast switching characteristics designed for high efficiency applications
- Low forward voltage drop combined with high current capability
- Surge overload rating supporting up to 30 A peak current
- Low reverse leakage current performance
Applications
- High frequency rectification circuits
- Free-wheeling diode implementations
- General purpose rectification in power supplies
Procurement Notes
Verify the specific ordering suffix matches the required tape and reel packaging configuration. Confirm compliance with applicable RoHS directives and lead-free finish requirements before procurement. Ensure the selected variant aligns with the manufacturer's current production status and availability constraints.
Selection Notes
Select this component for designs requiring a 400 V reverse voltage rating with a 1.0 A continuous current capacity. Consider the 200 ns reverse recovery time for high-speed switching requirements. Evaluate thermal management needs based on the specified junction-to-ambient thermal resistance and derating curves for ambient temperatures exceeding +75°C.
Part Context
This part belongs to the 1N4933 through 1N4937 series of fast recovery rectifiers manufactured by Diodes Incorporated. The series offers varying reverse voltage ratings from 50 V to 600 V while maintaining consistent current handling capabilities. The 1N4936 specifically targets applications requiring 400 V blocking capability.
Replacement Considerations
The datasheet explicitly recommends using the RS1A through RS1J series as replacements. These alternative components are suggested for new designs instead of this discontinued or not recommended for new design product.
