DA221TL

Diode Arrays Overview

The DA221TL is a high-reliability, small molded silicon epitaxial planar switching diode manufactured by ROHM Semiconductor. Designed for fast switching applications, it features two diode elements connected in series within a single package to achieve doubled forward voltage characteristics. The component operates with a maximum reverse voltage of 20V and an average rectified forward current of 100mA. It utilizes the EMD3 (SOT-416) surface-mount package, measuring 1.6x1.6mm with a thickness of 0.8mm. Key electrical parameters include a forward voltage of 1V at 10mA, a reverse current of 0.1µA at 15V, and a junction temperature range up to 150°C.

Diode Arrays Procurement Notes

Verify the specific suffix against official ROHM documentation to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required thermal and electrical ratings for the target application. Confirm RoHS compliance status directly from the manufacturer's latest datasheet before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component when a compact, high-speed switching solution with dual-series diode functionality is required. The 20V rating and 100mA current capacity suit low-power signal processing tasks. Consider the SOT-416 footprint for PCB layout compatibility and verify thermal management requirements against the specified junction temperature limits.

Diode Arrays Part Context

This device belongs to ROHM's line of small-signal switching diodes, engineered for efficiency and miniaturization. The DA221 series integrates multiple diode functions into a single surface-mount package, reducing board space and assembly complexity compared to discrete solutions.
