SD1A180A-13

Overview

The SD1A180A-13 is a SIDAC device manufactured by Diodes Incorporated, designed for overvoltage protection in electronic circuits. It operates within a breakover voltage range of 170 V to 190 V and supports a peak current of 1 A. The component utilizes the SMA surface-mount package (DO-214AC) for compact integration. It features a unidirectional structure suitable for single-channel applications. The device ensures reliable performance across an operating temperature range from -55 °C to +150 °C, providing robust transient suppression capabilities.

Feature Summary

• Provides bidirectional or unidirectional surge protection with precise triggering thresholds
• Utilizes compact SMA surface-mount packaging for automated assembly
• Engineered for high thermal stability across extended industrial temperature ranges

Applications

• Protection of communication interfaces against electrostatic discharge
• Surge suppression in consumer electronics power supplies
• Overvoltage protection for sensitive signal lines in automotive systems

Procurement Notes

Verify the specific datasheet revision and electrical characteristics directly with Diodes Incorporated before implementation. Confirm that the SMA package dimensions align with your PCB footprint requirements. Ensure compliance with RoHS and REACH standards as specified in the official product documentation. Cross-reference the part number suffix to confirm availability and manufacturing status.

Selection Notes

Select this component when circuit design requires a specific breakover voltage between 170 V and 190 V for transient suppression. Consider the SMA package size if space constraints are critical. Evaluate the 1 A peak current rating against expected surge levels. Verify thermal management needs given the wide operating temperature range up to 150 °C.

Part Context

This SIDAC belongs to the SD1 series of overvoltage protection devices from Diodes Incorporated. It complements other TVS diodes and thyristors in the manufacturer's portfolio, offering specialized triggering characteristics for line protection. The SMA package variant provides a cost-effective solution for high-volume consumer and industrial applications requiring reliable surge immunity.

Replacement Considerations

Check for direct substitutes such as the SD1A180E or SD1A180G from Diodes Incorporated, ensuring package compatibility. Verify equivalent breakover voltage ranges and current ratings before substitution. Consult official cross-reference guides for validated alternatives.
