1N5925BRLG

Single Zener Diodes Overview

The onsemi 1N5925BRLG is a silicon-oxide passivated Zener voltage regulator diode belonging to the 3 W DO-41 Surmetic 30 series. It provides a nominal Zener voltage of 10 V with a tolerance of ±5%. The device operates within a temperature range of -65°C to +200°C and features a maximum steady-state power dissipation of 3 W at a lead temperature of 75°C. Electrical characteristics include a reverse leakage current of 8 µA maximum at 8 V, a maximum Zener impedance of 4.5 Ω at the test current of 37.5 mA, and 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 environmental protection.
• Features a void-free, transfer-molded thermosetting plastic package that is corrosion resistant.
• Offers high surge capability rated at 98 W for 1 ms pulses.
• Guarantees maximum limits on up to six electrical parameters for design reliability.

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Protection against electrostatic discharge (ESD)
• Surge suppression applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'RLG' confirms the axial lead configuration and Pb-Free status as documented by onsemi. Ensure the procurement specification matches the required 3 W power dissipation and 10 V nominal voltage ratings. Confirm compliance with RoHS directives if applicable to the target assembly environment. Cross-reference the package outline CASE 59-10 for mechanical fitment requirements.

Single Zener Diodes Selection Notes

Select this component when a 10 V reference or clamp is required with a 3 W power handling capacity. The wide operating temperature range supports demanding thermal environments. Consider the low Zener impedance for stable regulation under varying load conditions. Verify that the axial lead format aligns with the printed circuit board layout and mounting constraints of the final design.

Single Zener Diodes Part Context

This part belongs to the 1N59xxB series of 3 W Zener diodes manufactured by onsemi. The series covers a broad voltage range from 3.3 V to 200 V, all housed in the standard DO-41 axial-lead plastic package. The 'B' designation indicates a ±5% voltage tolerance, while the 'RLG' suffix specifies the reel packaging and Pb-Free material composition.

Single Zener Diodes Replacement Considerations

Compatible replacements include other manufacturers' 1N5925B variants meeting the same JEDEC specifications. Ensure substitute parts maintain the 3 W power rating and DO-41 package dimensions for direct interchangeability without mechanical modification.
