Overview
The Lumimax Optoelectronic Technology 1N4735A is a silicon planar power Zener diode housed in a JEDEC DO-41 glass package. It provides a nominal Zener voltage of 6.2V with a tolerance of ±5%. The device supports a maximum power dissipation of 1W and features a low Zener impedance of 2 Ohms. Electrical characteristics include a maximum reverse leakage current of 10µA at 3V and a forward voltage of 1.2V at 200mA. The component operates within a junction temperature range up to 200°C and a storage temperature range from -65°C to +200°C.
Feature Summary
- Glass passivated junction construction for enhanced stability
- Low Zener impedance and low regulation factor
- High temperature soldering capability guaranteed
Applications
- Voltage reference circuits
- Overvoltage protection systems
- Clipper and clamper applications
Procurement Notes
Verify the manufacturer designation as Lumimax Optoelectronic Technology, distinct from other producers like Nexperia or onsemi offering identical part numbers. Confirm the specific electrical parameters match the provided datasheet, particularly the 2 Ohm impedance value. Ensure the DO-41 glass package type is specified correctly for your mounting requirements.
Selection Notes
Select this component when a stable 6.2V reference is required in through-hole designs. The DO-41 glass package offers robust thermal performance suitable for high-temperature environments. Consider the low impedance characteristic for applications demanding tight voltage regulation under varying load conditions.
Part Context
This component belongs to the 1N47xxA series of Zener diodes manufactured by Lumimax Optoelectronic Technology. The series covers a wide voltage range from 3.3V to 75V, all sharing the same DO-41 glass package and 1W power rating. The 'A' suffix consistently denotes a ±5% voltage tolerance across the entire product line.
Replacement Considerations
Compatible substitutes include the 1N4735A from manufacturers such as Nexperia, onsemi, and Microchip, provided they meet the same DO-41 package and 6.2V specification constraints.
