1N5371B-AP

Overview

The MCC 1N5371B-AP is a silicon planar Zener diode designed for voltage regulation applications. It operates in the breakdown region to maintain a stable reference voltage across varying load and line conditions. The device features a nominal Zener voltage of 60 V with a tolerance of ±5%. It supports a maximum power dissipation of 5 W at ambient temperatures up to 75°C, derating linearly above this threshold. The component utilizes an axial leaded package suitable for through-hole mounting on printed circuit boards.

Feature Summary

• Provides precise voltage regulation within a tight manufacturing tolerance band
• Capable of handling high continuous power dissipation for robust thermal performance
• Utilizes silicon planar technology for consistent electrical characteristics

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in power supply inputs
• Clamping applications in signal conditioning paths

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm availability and exact electrical tolerances. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the part number with current datasheets to validate compliance with RoHS and REACH standards prior to finalizing orders.

Selection Notes

Select this component when a 60 V regulated voltage point is required in high-power environments. Consider the 5 W power rating and thermal management requirements for the intended operating temperature range. Verify that the axial package style aligns with the mechanical constraints of the target PCB layout and assembly process.

Part Context

This component belongs to the 1N53xx series of high-power Zener diodes manufactured by Micro Commercial Components. The series offers a wide range of voltage options within the same physical footprint, allowing designers to standardize on a single package type while adjusting voltage ratings via different part numbers in the lineup.

Replacement Considerations

Direct replacements include the 1N5371B-TP variant from the same manufacturer, which shares identical electrical specifications but may differ in packaging format. Other manufacturers producing JEDEC registered 1N5371 equivalents with matching 60 V, 5 W, and ±5% tolerance ratings are also viable substitutes.
