1N5913BRL

Single Zener Diodes Overview

The onsemi 1N5913BRL is a silicon Zener voltage regulator diode from the 1N59xxB series, housed in an axial-lead DO-41 (Surmetic 30) plastic package. It features a nominal Zener voltage of 3.3 V with a ±5% tolerance and operates at a test current of 113.6 mA. The device provides a maximum steady-state power dissipation of 3 W at a lead temperature of 75°C and withstands a 98 W surge rating for 1 ms pulses. Electrical characteristics include a maximum reverse leakage current of 1 µA at 100 V and a maximum Zener impedance of 10 Ω at the test current.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junction technology to ensure superior operating characteristics and environmental protection within a transfer-molded plastic case.
• Offers high reliability through guaranteed maximum limits on up to six electrical parameters and robust ESD protection rated at Class 3 (>16 kV) per the Human Body Model.
• Features metallurgically enhanced internal contacts and corrosion-resistant external surfaces with readily solderable leads for secure mounting in any position.

Single Zener Diodes Applications

• Voltage regulation in automotive electronic systems
• Power supply reference circuits in industrial equipment
• Overvoltage protection in commercial and computer applications

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'RL' corresponds to the Tape & Reel shipping configuration containing 6000 units per reel as specified in the datasheet ordering information. Confirm the presence of the 'G' suffix if Pb-Free packaging is required, as standard availability may vary. Ensure compatibility with the DO-41 mechanical outline and verify lead length requirements against the thermal derating curves provided in the documentation.

Single Zener Diodes Selection Notes

Select this component when a precise 3.3 V reference is needed with a ±5% tolerance and a 3 W power handling capability. The axial-lead DO-41 package is suitable for through-hole mounting where higher power dissipation than conventional 1 W packages is required without increasing the physical footprint. Consider the specific test current of 113.6 mA for circuit design to ensure accurate voltage regulation under expected load conditions.

Single Zener Diodes Part Context

This part belongs to the 1N59xxB series of 3 W Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, all sharing the same axial-lead package and general mechanical characteristics. The 'B' suffix indicates a ±5% voltage tolerance, distinguishing it from other tolerance variants within the broader product family.

Single Zener Diodes Replacement Considerations

Compatible replacements include other manufacturers' 1N5913B devices meeting the JEDEC registered specifications for 3.3 V, 3 W Zener diodes in the DO-41 package. Verify that substitute parts match the 113.6 mA test current and 10 Ω maximum impedance to maintain equivalent performance in the application.

Single Zener Diodes FAQ
