Overview
The Central Semiconductor Corp 1N4624 BK TIN/LEAD is a single Zener diode designed for through-hole mounting in DO-35-2 packages. It features a nominal Zener voltage of 7.5 V with a 5% tolerance and a power dissipation rating of 250 mW. The device operates within a temperature range of -65°C to +200°C, maintaining a maximum reverse leakage current of 5 µA and a Zener impedance of 100 Ω at a test current of 5 mA.
Feature Summary
- Provides stable voltage regulation via the Zener breakdown effect in the reverse bias region.
- Engineered for high-temperature reliability with an operational limit extending to +200°C.
- Utilizes a glass-passivated junction structure compatible with standard axial leaded PCB layouts.
Applications
- Voltage reference circuits requiring precise potential levels.
- Overvoltage protection stages for sensitive electronic components.
- Clamping applications in signal processing paths.
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm plating composition and packaging format. Ensure that the requested variant matches the required thermal and electrical specifications for the intended operating environment before finalizing procurement orders.
Selection Notes
Select this component when a 7.5 V reference point is required in low-power applications. Confirm that the 250 mW dissipation rating aligns with the expected thermal load. Verify package compatibility with existing board footprints and ensure the operating temperature range meets system requirements.
Part Context
This part belongs to the 1N46xx series of glass-passivated Zener diodes manufactured by Central Semiconductor. These devices are characterized by their robust construction and suitability for general-purpose voltage regulation tasks in consumer and industrial electronics.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4624 equivalents. Verify pinout, voltage tolerance, and power ratings match exactly before substituting.
