1N4712 TR PBFREE

Overview

The Central Semiconductor Corp 1N4712 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 28 V with a 5% tolerance, tested at 50 μA. The device operates within a junction temperature range of -65°C to +200°C and dissipates up to 500 mW. Packaged in the DO-35 axial leaded case, it includes a maximum reverse leakage current of 0.01 μA and a maximum regulator current of 8.5 mA.

Feature Summary

• Designed for applications requiring extremely low operating current and low leakage
• Utilizes a standard DO-35 axial leaded package for through-hole mounting
• Operates reliably across an extended junction temperature range from -65°C to +200°C

Applications

• Low-level voltage regulation circuits
• Reference voltage sources in sensitive analog designs
• Protection against overvoltage transients in low-power systems

Procurement Notes

Verify that the ordering suffix PBFREE confirms lead-free plating compliance as specified by the manufacturer. Ensure the reel or cut tape packaging matches the assembly requirements. Confirm the specific marking code C4712 on the component body aligns with the datasheet documentation for quality assurance purposes.

Selection Notes

Select this component when circuit design demands minimal quiescent current consumption alongside stable voltage reference capabilities. The DO-35 package facilitates easy integration into traditional through-hole layouts. Consider the 50 μA test current requirement to ensure compatibility with low-power biasing networks.

Part Context

This part belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 1.8 V to 43 V, all sharing identical power dissipation ratings and package styles while varying in specific Zener voltage characteristics.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4712 equivalents in the DO-35 package. Verify that substitute parts maintain the same 50 μA test current and 500 mW power rating to ensure functional parity in existing designs.
