1N5382B-TP

Overview

The MCC 1N5382B-TP is a 5W Zener diode with a nominal voltage of 140V and ±5% tolerance. It operates in the -55°C to +150°C junction temperature range for DC conditions, housed in a DO-15 axial package. Key electrical parameters include a maximum dynamic impedance (ZZT) of 230 Ohms at 8mA test current, a reverse leakage current (IR) of 0.5µA at 106V, and a maximum regulator current (IZM) of 34mA. The device supports a surge current (IZSM) of 2.5A.

Feature Summary

• Provides stable voltage regulation within a wide operating temperature range suitable for demanding environments.
• Features low reverse leakage current to minimize power loss during non-conducting states.
• Constructed with epoxy meeting UL 94 V-0 flammability ratings for enhanced safety.

Applications

• Voltage reference circuits requiring high-voltage stability.
• Overvoltage protection stages in industrial power supplies.
• Clamping applications in high-voltage signal processing systems.

Procurement Notes

Verify component authenticity by checking for authorized distributor markings and original packaging seals. Confirm RoHS compliance status and specific suffix requirements such as halogen-free options if mandated by project specifications. Ensure storage conditions adhere to manufacturer guidelines to maintain lead integrity and prevent oxidation prior to soldering.

Selection Notes

Select this component when a precise 140V regulation point is required with moderate power handling capabilities. Consider the thermal resistance characteristics and derating curves for high-temperature environments. Evaluate the dynamic impedance against noise sensitivity requirements in the target circuit design.

Part Context

This part belongs to the 1N5338B through 1N5388B series of 5W Zener diodes manufactured by Micro Commercial Components. The series covers a broad voltage range from 5.1V to 200V, utilizing the standard DO-15 axial leaded package. It serves as a robust solution for general-purpose voltage regulation tasks in discrete semiconductor applications.

Replacement Considerations

Cross-reference with other manufacturers offering 140V 5W Zener diodes in the DO-15 package. Verify that substitute parts match the 230 Ohm dynamic impedance limit and 0.5µA reverse leakage specification to ensure circuit compatibility without redesign.
