Overview
The 1N4758G R0G is a silicon Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 56V with a tolerance of ±5% and a power dissipation rating of 1W. The device utilizes a DO-41 glass axial package, which is hermetically sealed to ensure stability and reliability. It operates within a temperature range of -65°C to +200°C and includes a tin-lead solder finish on its terminals.
Feature Summary
- Hermetically sealed glass compression bonded construction for corrosion resistance
- DO-41 through-hole package mounting type
- Zener voltage range spanning from 3.3V to 56V
Applications
- Voltage regulation in industrial circuits
- Clipping applications in entertainment systems
- Military and space electronic equipment
Procurement Notes
Verify the specific suffix 'R0G' against official Taiwan Semiconductor documentation to confirm reel packaging specifications. Ensure the component matches the standard 1N4758G electrical characteristics. Confirm lead material composition and RoHS compliance status as defined in the manufacturer's datasheet for the exact part number variant.
Selection Notes
Select this component for general-purpose applications requiring stable voltage reference at 56V. The DO-41 package suits through-hole designs. Consider the high operating junction temperature capability for demanding environments. Verify thermal derating requirements above 50°C when designing the circuit layout.
Part Context
This part belongs to the 1N47XXG series of 1W Zener diodes offered by Taiwan Semiconductor. The series covers voltages from 3.3V to 56V. These devices are designed for robust performance in harsh conditions due to their hermetic sealing and glass passivation.
Replacement Considerations
Compatible substitutes include the 1N4758A from other manufacturers such as onsemi or Central Semiconductor. Ensure the replacement maintains the DO-41 package and 1W power rating. Verify that the substitute meets the same hermetic sealing and voltage tolerance requirements.
