1N4700 TR PBFREE

Overview

The Central Semiconductor Corp 1N4700 TR PBFREE is a silicon Zener diode designed for low-level applications requiring extremely low operating current and leakage. It features a nominal Zener voltage of 13 V with a 5% tolerance, tested at 50 μA. The device dissipates up to 500 mW and operates within a junction temperature range of -65°C to +200°C. Packaged in the DO-35 axial leaded case, it exhibits a maximum reverse leakage current of 0.05 μA and supports a maximum regulator current of 19.0 mA.

Feature Summary

• Designed for applications requiring extremely low operating current and low leakage
• Utilizes a standard DO-35 axial leaded package configuration
• Provides stable voltage regulation across a wide thermal operating range

Applications

• Low-level voltage reference circuits
• Precision voltage regulation modules
• Electronic protection against overvoltage conditions

Procurement Notes

Verify that the ordering suffix matches the required plating specification. The PBFREE designation indicates lead-free compliant devices. Confirm the TR suffix aligns with the desired bulk packaging format. Ensure the component meets RoHS standards if applicable to your manufacturing process. Cross-reference the marking code C4700 for physical identification upon receipt.

Selection Notes

Select this component when circuit design demands minimal quiescent current consumption alongside reliable voltage clamping. The DO-35 package facilitates through-hole mounting on printed circuit boards. Evaluate the 500 mW power dissipation rating against expected thermal loads. Consider the specific test current requirements for accurate voltage regulation in sensitive analog environments.

Part Context

This part belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes manufactured by Central Semiconductor. The series covers a voltage range from 1.8 V to 43 V, all sharing identical mechanical outlines and general electrical characteristics. These components are engineered specifically for precision applications where low noise and minimal leakage are critical performance factors.

Replacement Considerations

Direct parameter-equivalent substitutes include parts from other manufacturers utilizing the DO-35 package. Verify that any replacement maintains the 13 V nominal voltage, 500 mW power rating, and comparable leakage specifications to ensure circuit compatibility.
