SD1A220G

Overview

The SD1A220G is a silicon unidirectional thyristor (SIDAC) manufactured by Diodes Incorporated. It operates within an operating junction temperature range of -40°C to +125°C and features a peak repetitive off-state voltage (VDRM) of 190 V. The device supports an on-state RMS current of 1 A at 80°C ambient temperature. Its breakover voltage (VBO) ranges from 210 V to 230 V, with a maximum holding current of 60 mA. The component utilizes a JEDEC DO-15 molded plastic case and complies with RoHS 2011/65/EU standards.

Feature Summary

Compact package design for spacing saving
Lead-free plating terminals
RoHS 2011/65/EU compliant

Applications

Gas igniters

Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure compliance with the latest revision standards. Confirm that the DO-15 package dimensions match the required PCB footprint layout. Ensure storage conditions remain within the specified -40°C to +150°C range prior to assembly to maintain component integrity.

Selection Notes

Select this component when a precise breakover voltage between 210 V and 230 V is required for overvoltage protection or triggering applications. Verify that the circuit can accommodate the 1 A on-state RMS current limit. Ensure the thermal management strategy accounts for the 15 °C/W junction-to-case thermal resistance under continuous operation.

Part Context

This part belongs to the SIDAC family of silicon unidirectional thyristors designed for high-voltage triggering applications. It serves as a reliable switching element in circuits requiring stable breakover characteristics. The DO-15 package provides robust mechanical stability for through-hole mounting in industrial environments.
