1N5352B

Overview

The onsemi 1N5352B is a single Zener voltage regulator diode with a nominal reverse Zener voltage of 15 V and a maximum steady-state power dissipation of 5 W. It features a ±5% tolerance, a test current (IZT) of 75 mA, and a maximum Zener impedance (ZZT) of 2.5 Ω at the test current. The device operates within a junction temperature range of -65°C to +200°C, with a maximum DC operating temperature of 150°C. It utilizes an axial lead Case 017AA plastic package.

Feature Summary

• Utilizes silicon-oxide passivated junctions for improved operating characteristics
• Features surge rating capability up to 180 W at 8.3 ms pulse width
• Provides protection in common environmental conditions via transfer-molded plastic packaging

Applications

• Voltage regulation circuits requiring 15 V reference
• High-power transient suppression applications
• General-purpose rectification and clamping

Procurement Notes

Verify the specific ordering suffix when purchasing. The 'G' suffix indicates a Pb-Free package. Confirm whether the requirement is for bulk box shipping or tape and reel configuration, as these are distinct part numbers within the series. Ensure the component meets RoHS compliance standards if required by the application specifications.

Selection Notes

Select this component for applications requiring a 15 V Zener voltage with high power handling capabilities. The 5 W dissipation rating allows operation at higher currents compared to lower-power variants. Consider the thermal resistance and ambient temperature derating requirements to ensure the junction temperature remains within the specified limits during continuous operation.

Part Context

This device belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators. The series covers a wide voltage range from 3.3 V to 200 V. The 1N5352B specifically addresses the 15 V segment of this lineup, offering tight electrical limits and robust construction suitable for demanding industrial environments.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5352B equivalents that meet the same JEDEC registration standards. Verify that replacement parts maintain the 5 W power rating, 15 V nominal voltage, and ±5% tolerance to ensure circuit compatibility.
