CMZ5917B TR13

Single Zener Diodes Overview

The Central Semiconductor CMZ5917B TR13 PBFREE is a surface mount silicon Zener diode with a nominal voltage of 4.7 V and ±5% tolerance. It operates within a power dissipation range of 0.5 W to 1.5 W, depending on thermal conditions, and features a maximum reverse current of 5.0 µA at 1.5 V. The component utilizes an SMA case for compact board space efficiency and supports peak forward surge currents up to 10 A. It is designed for commercial, industrial, computer, and automotive applications requiring high reliability in small-scale designs.

Single Zener Diodes Feature Summary

• Super miniature SMA case design occupies significantly less board space than larger SMB packages
• C bend construction provides mechanical strain relief when mounted on printed circuit boards
• High reliability rating suitable for demanding commercial, industrial, and automotive environments

Single Zener Diodes Applications

• General voltage regulation circuits
• Voltage reference functions
• Over-voltage protection systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating composition and packaging format. The TR13 suffix indicates tape and reel packaging on 13-inch reels. Ensure the PB FREE designation aligns with environmental compliance requirements for your assembly process. Cross-reference the marking code C5917B with official datasheets to authenticate component identity during incoming inspection.

Single Zener Diodes Selection Notes

Select this component when a compact SMA package is required for 4.7 V regulation with tight tolerance constraints. Evaluate thermal management needs carefully, as power dissipation drops to 0.5 W without adequate copper pad area. Consider the low reverse leakage current for sensitive reference applications. Verify that the operating temperature range meets the specific environmental demands of the target deployment scenario.

Single Zener Diodes Part Context

This device belongs to the CMZ5913B through CMZ5956B series of surface mount Zener diodes manufactured by Central Semiconductor. The series covers a wide voltage range from 3.3 V to 200 V, all sharing the same SMA footprint and general feature set. This specific model represents the mid-range voltage option within the lineup, balancing performance and physical size for dense circuit layouts.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 4.7 V nominal voltage, SMA package, and 1.5 W power rating. Verify equivalent impedance and leakage specifications to ensure circuit compatibility. Check for identical marking codes if visual identification is required for quality control processes.
