Overview
The Vishay 1N4246GPHE3/73 is a glass-passivated junction plastic rectifier featuring the Superectifier structure. It provides a maximum repetitive peak reverse voltage of 400 V and supports a maximum average forward rectified current of 1.0 A. The device exhibits a low leakage current of 1.0 μA at rated DC blocking voltage and handles a peak forward surge current of 25 A. It operates within a junction temperature range of -65 °C to +160 °C and utilizes the DO-41 (DO-204AL) axial through-hole package.
Feature Summary
- Superectifier structure designed for high reliability applications
- Cavity-free glass-passivated junction construction
- Low forward voltage drop characteristics
- High forward surge capability
Applications
- General purpose rectification in power supplies
- Inverter circuits
- Converter applications
- Freewheeling diode usage
Procurement Notes
Verify component authenticity by checking manufacturer markings against datasheet specifications. Confirm RoHS compliance status via the E3 suffix designation. Validate package dimensions and lead finish against JESD standards. Ensure storage conditions maintain integrity prior to soldering. Review official documentation for any recent product change notices or obsolescence alerts.
Selection Notes
Select this component when a 400 V reverse voltage rating is required alongside a 1.0 A continuous current capacity. The DO-41 package suits through-hole mounting requirements. Consider the Superectifier technology for enhanced reliability compared to standard junctions. Verify thermal management capabilities align with the specified junction temperature limits during operation.
Part Context
This part belongs to the 1N424xGP series, which includes variants with different reverse voltage ratings ranging from 200 V to 1000 V. All members share identical physical packages and forward current characteristics. The GP designation indicates the Superectifier structure, while the E3 suffix confirms RoHS compliance. This specific model represents the 400 V option within the lineup.
Replacement Considerations
Direct replacements include other 1N4246GP variants from Vishay with different packaging codes such as /54. Cross-manufacturer equivalents must match the 400 V reverse voltage, 1.0 A forward current, and DO-41 package form factor.
