1N5352BRLG

Overview

The onsemi 1N5352BRLG is a single-channel Zener voltage regulator diode from the 1N53 Series, designed for robust performance in axial lead applications. It features a nominal Zener voltage of 15 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at a lead temperature of 75°C. The device operates within a junction and storage temperature range of -65°C to +200°C. Key electrical parameters include a test current (IZT) of 75 mA, a maximum Zener impedance (ZZT) of 2.5 Ω, and a maximum reverse leakage current of 1 μA. It utilizes a DO-15 (Case 017AA) plastic package.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and tight parameter limits.
• Features a void-free, transfer-molded thermosetting plastic case that provides corrosion resistance and protection in common environmental conditions.
• Offers high surge capability with a rating of up to 180 W at 8.3 ms pulse width.
• Includes an ESD rating of Class 3 (>16 kV) per the Human Body Model.

Applications

• Voltage regulation in general-purpose electronic circuits
• Surge protection for sensitive components
• Reference voltage sources in power supplies

Procurement Notes

Verify the specific ordering suffix 'RLG' corresponds to the tape and reel shipping configuration (4000 units/reel) as defined in the manufacturer's ordering information. Confirm RoHS compliance status and Pb-Free packaging availability through official documentation before procurement. Ensure the application environment remains within the specified thermal derating curves to maintain the 5 W power dissipation limit.

Selection Notes

Select this component when a stable 15 V reference with high power handling is required. The 1N5352B variant specifically offers a tighter ±5% voltage tolerance compared to standard variants. Consider the axial lead package dimensions and thermal resistance characteristics for heat sinking requirements. Verify that the maximum DC Zener current does not exceed the calculated limit based on the actual Zener voltage and 5 W power constraint.

Part Context

This part belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators. The series covers a wide Zener voltage range from 3.3 V to 200 V. All devices in this family share the same mechanical Case 017AA axial lead package and utilize silicon-oxide passivation technology for enhanced reliability and environmental protection.

Replacement Considerations

Compatible substitutes within the same series include other 1N53xxB devices with similar voltage ratings, such as 1N5351B or 1N5353B, provided the specific Zener voltage matches the circuit requirements. Cross-referencing with other manufacturers' 5 W axial Zener diodes requires verification of pinout, package dimensions, and electrical tolerances.
