1N5353B

Overview

The onsemi 1N5353B is a silicon-oxide passivated junction Zener voltage regulator diode with a nominal reverse Zener voltage of 16 V and a maximum steady-state power dissipation of 5 W. It features a ±5% voltage tolerance, a test current (IZT) of 75 mA, and a maximum Zener impedance (ZZT) of 2.5 Ohms at the test current. The device operates within a temperature range of -65°C to +150°C for DC conditions and up to +200°C for pulsed applications. It utilizes an axial lead Case 017AA plastic package.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection.
• Provides high surge rating capability up to 180 W at 8.3 ms pulse width.
• Features robust ESD protection rated at Class 3 (>16 kV) per Human Body Model.
• Guarantees maximum limits on up to six electrical parameters for consistent performance.

Applications

• Voltage regulation across broad operating current and temperature ranges
• Circuits requiring high surge stress withstand capability
• Applications needing flexible axial-lead mounting terminals

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 (1000 units/box) or tape and reel packaging (4000 units/reel). Ensure the component meets RoHS compliance standards if required by the application specifications.

Selection Notes

Select this component for applications requiring a 16 V reference with a 5 W power handling capacity. The ±5% tolerance suits general-purpose regulation where tighter precision is not critical. Consider the thermal resistance characteristics and derating requirements above 25°C to ensure reliable operation under continuous load conditions.

Part Context

This part belongs to the 1N53 Series, a complete line of 5 Watt Surmetic 40 Zener Voltage Regulators. The series covers a wide voltage range from 3.3 V to 200 V, all housed in the same axial lead transfer-molded plastic package designed for common environmental conditions.

Replacement Considerations

Cross-reference with other manufacturers offering the JEDEC registered 1N5353B specification. Verify that substitute components match the 16 V nominal voltage, 5 W power dissipation, and DO-15/Axial mechanical dimensions to ensure physical compatibility.
