Overview
The 2N5225 is a single Zener diode manufactured by Central Semiconductor Corp, designed for through-hole mounting in the DO-35 axial package. It features a nominal Zener voltage of 10 V with a tolerance of ±5%. The device has a maximum power dissipation of 500 mW and operates within a temperature range of -65°C to +200°C. Key electrical parameters include a maximum reverse leakage current of 5 µA at 7.4 V, a Zener impedance of 19 ohms, and a test current of 25 mA.
Feature Summary
- Provides stable voltage regulation via Zener breakdown characteristics
- Capable of operation in extreme high-temperature environments up to 200°C
- Utilizes an axial leaded package suitable for standard through-hole PCB assembly
Applications
- Voltage reference circuits requiring stable DC levels
- Overvoltage protection stages in electronic systems
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific ordering suffix TIN/LEAD to confirm tin-lead plating availability, as this affects RoHS compliance status. Confirm the manufacturer part number matches exactly to ensure correct voltage and package specifications. Check current stock levels and production lead times directly with authorized distributors or the manufacturer, as availability may vary.
Selection Notes
Select this component when a 10 V Zener reference is required in a DO-35 through-hole package. Ensure the circuit design accommodates the 500 mW power dissipation limit and the specified operating temperature range. Verify that the 19 ohm Zener impedance meets the noise and regulation requirements of the application.
Part Context
This component belongs to the 1N52xx series of glass-passivated junction Zener diodes produced by Central Semiconductor Corp. These devices are characterized by high reliability and stability, making them suitable for industrial and commercial applications where robust voltage regulation is necessary.
Replacement Considerations
Cross-reference with other manufacturers offering 1N5225 equivalents in DO-35 packages. Verify that substitute parts match the 10 V nominal voltage, 500 mW power rating, and ±5% tolerance to maintain circuit performance.
