Overview
The Diodes Incorporated 1N4935-T is a single-phase, fast recovery rectifier diode housed in a DO-41 plastic package. It features a peak repetitive reverse voltage of 200 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 5.0 µA at rated DC blocking voltage. Reverse recovery time is specified at 200 ns. It supports a non-repetitive peak forward surge current of 30 A and operates within a junction temperature range of -65 to +150 °C.
Feature Summary
- Fast switching capability 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 characteristics
Applications
- High frequency rectification circuits
- General purpose power supply designs
- DC-DC converter stages
Procurement Notes
Verify the specific manufacturer source when ordering, as the 1N4935-T designation appears across multiple vendors including Rectron and Sensitron. Confirm that the component matches the Diodes Incorporated datasheet DS26002 Rev. 8 if sourcing from this specific manufacturer. Check RoHS compliance status and lead-free finish requirements against project specifications before finalizing procurement.
Selection Notes
Select this component for applications requiring fast recovery times around 200 ns and a 200 V reverse voltage rating. Ensure the thermal environment allows for the specified 1.0 A average rectified current without exceeding the maximum junction temperature. Consider the RS1A-RS1J series as recommended alternatives for new designs due to obsolescence notices.
Part Context
This component belongs to the 1N4933 through 1N4937 family of fast recovery rectifiers manufactured by Diodes Incorporated. The 'T' suffix indicates tape and reel packaging for automated assembly. The datasheet explicitly marks these devices as not recommended for new design, suggesting newer alternatives like the RS1A-RS1J series.
Replacement Considerations
Diodes Incorporated recommends using the RS1A through RS1J series as replacements for new designs. Verify electrical compatibility regarding voltage ratings and recovery times when substituting with other manufacturers' equivalents.
FAQ
Is the 1N4935-T recommended for new designs?
No, the datasheet explicitly states that the 1N4933-1N4937 series is not recommended for new design and suggests using the RS1A-RS1J series instead.
What is the maximum operating junction temperature?
The maximum operating and storage temperature range extends up to +150 °C.
