1N5343BRL

Single Zener Diodes Overview

The onsemi 1N5343BRL is a 5 Watt Zener diode from the Surmetic 40 series, housed in an axial lead Case 017AA plastic package. It provides a nominal reverse Zener voltage of 7.5 V with a ±5% tolerance range spanning 7.13 V to 7.88 V at a test current of 175 mA. The device features a maximum Zener impedance of 200 Ω and supports a maximum DC regulator current of 630 mA. It withstands surge currents up to 180 W at 8.3 ms pulses and offers an ESD rating exceeding 16 kV per the Human Body Model.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and tight electrical limits.
• Encased in void-free, transfer-molded thermosetting plastic that resists corrosion and ensures solderability.
• Capable of handling high maximum DC currents when paired with adequate heat sinking due to low thermal resistance design.

Single Zener Diodes Applications

• Voltage regulation across broad operating current and temperature ranges
• Protection against high surge stresses in electronic circuits
• General purpose voltage reference applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'G' indicates Pb-Free packaging availability as stated in the datasheet. Confirm the 'R' suffix corresponds to the Tape & Reel shipping format containing 4000 units per reel. Ensure the component matches the JEDEC registered type number designation for the required ±5% tolerance level before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a stable 7.5 V reference is required within a 5 Watt power dissipation envelope. The axial lead configuration allows for flexible mounting positions and compatibility with standard through-hole assembly processes. Consider the thermal resistance characteristics and derating requirements above 25°C to ensure reliable operation under steady-state conditions.

Single Zener Diodes Part Context

This part belongs to the 1N53xxB series of 5 Watt Zener voltage regulators manufactured by onsemi. The series covers a wide voltage selection from 3.3 V to 200 V, utilizing robust axial lead packages designed for common environmental protection. The 1N5343B variant specifically targets the lower end of the mid-voltage spectrum, offering precise regulation capabilities for various industrial and commercial electronics.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5343 equivalents ensuring identical 7.5 V nominal voltage, 5 Watt power rating, and axial lead package dimensions. Verify that substitute components meet the same ±5% tolerance and impedance specifications to maintain circuit performance integrity.
