Overview
The 1N4707 BK TIN/LEAD is a single Zener diode manufactured by Central Semiconductor Corp, housed in a DO-35-2 through-hole package. It features a nominal Zener voltage of 20 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 reverse leakage current of 10 nA at 15.2 V and a forward voltage of 1.5 V at 100 mA.
Feature Summary
- Provides stable voltage regulation via Zener breakdown characteristics
- Designed for through-hole mounting in standard DO-35 packages
- Capable of operation across an extended industrial temperature range
Applications
- Voltage reference circuits requiring precise 20 V levels
- Overvoltage protection stages in low-power electronics
- Clamping applications in signal conditioning paths
Procurement Notes
Verify the specific ordering suffix (BK vs TR) to confirm bulk or tape-and-reel packaging before procurement. Confirm RoHS compliance status directly with the manufacturer as specifications may vary by production batch. Ensure the tin/lead lead finish matches your assembly process requirements. Request current availability and lead times from authorized distributors as this component may be subject to special order constraints.
Selection Notes
Select this component when a 20 V Zener voltage with 500 mW power rating is required in a compact axial leaded form factor. The DO-35 package suits space-constrained PCB layouts. Consider the ±5% tolerance for applications needing moderate precision. Verify that the 10 nA leakage current meets the sensitivity requirements of the target circuit design.
Part Context
This part belongs to the 1N47xx series of Zener diodes produced by Central Semiconductor. These components are widely used in general-purpose electronic designs for voltage regulation and protection. The 1N4707 specifically targets the 20 V segment of this extensive product line, offering a reliable solution for standard voltage reference needs.
Replacement Considerations
Cross-reference with other manufacturers' 1N4707 equivalents such as those from ON Semiconductor or Vishay. Ensure substitute parts match the 20 V Zener voltage, 500 mW power rating, and DO-35 package dimensions. Verify that the replacement's leakage current and impedance characteristics are compatible with the original design specifications.
