Overview
The Central Semiconductor Corp 1N4711 BK TIN/LEAD is a single Zener diode designed for through-hole mounting in the DO-35-2 package. It features a nominal Zener voltage of 27 V with a 5% tolerance and a power dissipation rating of 500 mW. Key electrical characteristics include a maximum reverse leakage current of 0.01 uA, a Zener impedance of 20.4 ohms, and a test current of 8.8 mA. The device operates within a temperature range of -65°C to +200°C.
Feature Summary
- Provides stable voltage regulation via Zener breakdown mechanism
- Constructed for reliable through-hole PCB integration
- Engineered for high-temperature operational environments
Applications
- Voltage reference circuits
- Overvoltage protection stages
- Power supply regulation modules
Procurement Notes
Verify the specific ordering suffix matches the required lead time and material composition. Confirm that the tin/lead plating complies with applicable environmental regulations for the intended deployment region. Ensure the DO-35-2 package dimensions align with the target board layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a 27 V reference point is required with low leakage characteristics. The 500 mW rating supports moderate current applications compared to lower-power variants. Verify that the operating environment remains within the specified thermal limits to maintain parameter stability and device longevity during continuous operation.
Part Context
This part belongs to the Central Semiconductor 1N4711 series of Zener diodes. It utilizes the standard DO-35 glass passivated junction construction. The tin/lead finish indicates a specific terminal plating option distinct from lead-free alternatives within the same product family line.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4711 specifications. Verify pinout compatibility and thermal resistance values. Ensure substitute parts meet the 27 V Zener voltage and 500 mW power dissipation requirements.
