Overview
The Taiwan Semiconductor 1N4936GHB0G is a fast recovery rectifier diode belonging to the 1N493xG series. It features a single silicon die in a DO-204AL (DO-41) package with pure tin-plated leads. The device supports an average forward current of 1 A and a repetitive peak reverse voltage of 400 V. Key electrical parameters include a maximum forward voltage of 1.2 V at 1 A, a reverse recovery time of 200 ns, and a junction temperature range from -55°C to +150°C. The component is halogen-free and meets UL 94V-0 flammability standards.
Feature Summary
- AEC-Q101 qualified for automotive reliability
- Fast switching capability for high efficiency
- High surge current capability
- Low leakage current
Applications
- DC to DC converter
- Switching mode converters and inverters
- General purpose rectification
Procurement Notes
Verify that the specific suffix 'HB0G' aligns with the manufacturer's standard ordering codes for the 1N4936G variant. Confirm the presence of the 'H' designation indicating AEC-Q101 qualification. Ensure the packaging format matches the required tape and reel or ammo box specifications. Cross-reference the date code and factory marking against the latest datasheet version I2104 to confirm authenticity and compliance.
Selection Notes
Select this component when a 400V rated fast recovery rectifier is required for general-purpose or automotive applications. The DO-204AL package suits through-hole mounting. Consider the 200 ns reverse recovery time for switching frequencies where standard rectifiers may exhibit excessive losses. Verify thermal management requirements based on the 65 °C/W junction-to-ambient thermal resistance rating under expected load conditions.
Part Context
This part belongs to the 1N493xG series, which covers reverse voltages from 50V to 600V. The 'G' suffix indicates RoHS compliance and halogen-free construction. The 'H' suffix specifically denotes AEC-Q101 qualification. The series utilizes a glass-passivated junction structure designed for high reliability and low cost in industrial and consumer electronics.
Replacement Considerations
Direct substitutes within the same series include other 1N493xG variants with different voltage ratings, such as 1N4935G or 1N4937G, provided the voltage requirement is met. Generic equivalents like the 1N400x series are not suitable due to slower recovery times. Verify pinout compatibility and thermal characteristics before substitution.
