1N5338BRLG

Single Zener Diodes Overview

The onsemi 1N5338BRLG is a single-channel Zener voltage regulator diode from the 1N53 series, designed for high-power applications. It features a nominal Zener voltage of 5.1 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at 25°C. The device utilizes an axial lead DO-15 (Surmetic 40) package for through-hole mounting. Key electrical characteristics include a reverse leakage current of 1 µA at 1 V, a maximum Zener impedance of 1.5 Ω at the test current of 240 mA, and a forward voltage of 1.2 V max at 1 A. It operates within a temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and tight parameter limits.
• Features a void-free, transfer-molded thermosetting plastic package that provides corrosion resistance and environmental protection.
• Capable of handling surge currents up to 180 W at 8.3 ms pulse width.

Single Zener Diodes Applications

• High power rating stabilization circuits
• Voltage limiting circuits

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'RLG' against official documentation to confirm tape and reel packaging specifications. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Cross-reference the part number with the manufacturer's latest datasheet revision to confirm active status and any potential design changes.

Single Zener Diodes Selection Notes

Select this component when a stable 5.1 V reference or regulation point is required in high-power environments. The 5 W power rating allows for significant current handling compared to lower-power alternatives. Consider the axial lead package constraints for PCB layout and ensure adequate thermal management is available to maintain performance within the specified operating temperature range.

Single Zener Diodes Part Context

This component belongs to the 1N53 series of 5 Watt Surmetic 40 Zener Voltage Regulators manufactured by onsemi. The series covers a wide Zener voltage range from 3.3 V to 200 V, offering various options for different voltage regulation needs while maintaining consistent mechanical and thermal characteristics across the product line.

Single Zener Diodes Replacement Considerations

Compatible replacements include other manufacturers' 1N5338B variants, such as those from Motorola or STMicroelectronics, provided they meet the same 5.1 V nominal voltage, 5 W power rating, and DO-15 package dimensions.
