1N5371B

Overview

The onsemi 1N5371B is a silicon Zener diode with a nominal voltage of 60 V and ±5% tolerance. It operates in an axial leaded Surmetic 40 package (DO-201) for through-hole mounting. The device dissipates up to 5 W at 25°C, derating linearly above this temperature. Electrical characteristics include a maximum impedance of 40 Ω at 20 mA test current, reverse leakage of 1.2 µA at 45.5 V, and a maximum DC current of 79 mA. It withstands a surge rating of 180 W for 8.3 ms pulses.

Feature Summary

• Utilizes silicon-oxide passivated junction technology for stable operation across environmental conditions.
• Features a void-free, transfer-molded plastic case providing corrosion resistance and solderability.
• Offers high surge current capability suitable for transient protection applications.

Applications

• Voltage regulation in power supply circuits
• Transient voltage suppression against electrical surges
• Reference voltage generation in electronic instrumentation

Procurement Notes

Verify the specific ordering suffix when purchasing. The 'G' suffix indicates a Pb-Free package compliant with RoHS standards. Confirm that the required component matches the standard JEDEC B-suffix designation for ±5% tolerance. Ensure the procurement specification aligns with the manufacturer's current packaging options, such as box or tape-and-reel quantities.

Selection Notes

Select this component for designs requiring a precise 60 V reference point with moderate power handling capabilities. The axial lead configuration facilitates easy integration into printed circuit boards using standard through-hole assembly techniques. Consider the thermal resistance characteristics when designing heat dissipation strategies for continuous high-current operations.

Part Context

This part belongs to the 1N53 Series, a comprehensive family of 5 Watt Zener regulators manufactured by onsemi. The series spans a wide voltage range from 3.3 V to 200 V, utilizing identical mechanical packaging. This standardization allows designers to maintain consistent board layouts while adjusting voltage parameters across different product variants within the same line.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N5371B JEDEC designation. Verify that substitute components match the 5 W power dissipation, 60 V nominal voltage, and DO-201 package dimensions. Ensure equivalent electrical parameters, specifically the 40 Ω impedance and 1.2 µA leakage current limits.
