1N5352BG

Overview

The onsemi 1N5352BG is a 5 Watt Zener diode with a nominal voltage of 15 V and ±5% tolerance. It operates in an axial lead Case 017AA package. Key electrical parameters include a maximum impedance of 2.5 Ohms at 75 mA test current, reverse leakage of 1 µA at 11.5 V, and a forward voltage of 1.2 V max at 1 A. The device withstands up to 180 W surge power (8.3 ms) and functions within -65°C to +150°C for DC conditions.

Feature Summary

• Utilizes silicon-oxide passivated junction technology for improved operating characteristics
• Features robust surge capability rated up to 180 W at 8.3 ms pulse width
• Encased in void-free, transfer-molded thermosetting plastic for environmental protection

Applications

• Voltage regulation circuits requiring high power dissipation
• Surge protection applications utilizing high peak current ratings
• General purpose reference voltage generation

Procurement Notes

Verify the specific suffix 'G' confirms Pb-Free packaging status as defined by manufacturer standards. Confirm Case 017AA mechanical dimensions match board layout requirements. Ensure thermal management design accounts for the 25°C/W junction-to-lead resistance at specified lead lengths. Validate compliance with RoHS directives if required by end-product specifications.

Selection Notes

Select this component when a 15 V regulation point is needed with 5 W continuous power handling. The ±5% tolerance suits applications requiring tighter voltage limits than standard types. Consider the axial lead format for through-hole mounting where high thermal mass is beneficial. Evaluate the low leakage current specification against circuit sensitivity requirements.

Part Context

This part belongs to the 1N53 Series of Surmetic 40 Zener Voltage Regulators. The series covers a wide voltage range from 3.3 V to 200 V. All devices share the same axial lead plastic package construction and silicon-oxide passivation process, ensuring consistent reliability across the product family.

Replacement Considerations

Cross-reference with other manufacturers offering 1N5352B equivalents. Verify that substitute parts maintain the 5 W power rating and 15 V nominal voltage. Check that replacement packages match Case 017AA dimensions for physical compatibility.
