Overview
The Fairchild Semiconductor 1N4935GP is a fast recovery rectifier diode designed for high-efficiency switching applications. It features a glass-passivated junction and metalurgically bonded construction within a DO-41 package. The device supports a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage of 200 V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 30 A, a maximum reverse current of 5 uA, and a typical reverse recovery time of 150 ns. It operates reliably across a temperature range from -55°C to +150°C.
Feature Summary
- Glass-passivated junction provides high reliability and low leakage current
- Metalurgically bonded construction ensures robust mechanical stability
- Fast switching capability optimized for high-frequency efficiency
Applications
- High-frequency rectification circuits
- Free-wheeling diodes in power supplies
- General-purpose fast recovery applications
Procurement Notes
Verify the specific manufacturer designation, as the 1N4935GP part number is historically associated with Vishay General Semiconductor. Confirm that the supplied component matches the Fairchild Semiconductor datasheet specifications if sourced under this brand name. Ensure the package type is DO-41 and the junction is glass-passulated. Cross-reference the marking code on the diode body to confirm authenticity and origin before integration into production.
Selection Notes
Select this component for designs requiring a standard 1 A fast recovery rectifier with a 200 V blocking voltage. The DO-41 through-hole package is suitable for general PCB mounting where space allows. Consider the 150 ns reverse recovery time for switching frequency limitations. Verify thermal management requirements, as the device dissipates power based on forward voltage drop and load current.
Part Context
The 1N4935 series belongs to a family of glass-passivated fast recovery rectifiers widely used in consumer and industrial electronics. These diodes are characterized by their rugged construction and consistent performance in high-reverse-voltage environments. The GP suffix typically denotes a glass-passivated junction variant, distinguishing it from plastic-encapsulated counterparts.
Replacement Considerations
Equivalent parts include the 1N4935RLG (onsemi) and 1N4935G (Vishay). Verify pinout compatibility and ensure the substitute meets the same 1 A current and 200 V voltage ratings.
