Overview
The Central Semiconductor Corp 1N4700 BK TIN/LEAD is a single silicon Zener diode designed for through-hole mounting in the DO-35-2 package. It provides a nominal Zener voltage of 13 V with a 5% tolerance and a maximum power dissipation of 500 mW. The device operates within a junction temperature range of -65°C to +175°C, featuring a maximum reverse leakage current of 50 nA and a test current of 50 µA.
Feature Summary
- Provides stable voltage regulation via sharp reverse breakdown characteristics
- Constructed with hermetically sealed glass encapsulation for high reliability
- Features tin/lead plated axial leads for standard through-hole integration
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in electronic systems
- General-purpose clipping and clamping applications
Procurement Notes
Verify that the specific ordering suffix matches the required lead finish and packaging configuration. Confirm RoHS compliance status as indicated in official documentation, noting that tin/lead variants may differ from lead-free specifications. Ensure the manufacturer designation aligns with Central Semiconductor Corp requirements for the intended design implementation.
Selection Notes
Select this component when a 13 V Zener voltage with 500 mW power handling is required in a compact DO-35 form factor. Consider the specified thermal resistance and operating temperature limits relative to the application environment. Evaluate the low leakage current specification against circuit sensitivity requirements to ensure proper noise performance.
Part Context
This part belongs to the 1N47 series of silicon Zener diodes manufactured by Central Semiconductor. These components are characterized by their robust mechanical data and consistent electrical parameters across the series. The DO-35 package allows for efficient PCB layout while maintaining reliable thermal dissipation capabilities for steady-state operations.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4700 equivalents to verify pinout compatibility and parameter matching. Ensure substitute parts meet or exceed the 500 mW power rating and 13 V Zener voltage tolerance. Validate that alternative packages maintain the same axial lead spacing for direct board replacement.
