CMLSH-4DO TR PBFREE

Diode Arrays Overview

The CMLSH-4DO is a surface mount silicon dual, isolated opposing Schottky diode in an SOT-563 package. It contains two electrically isolated 40V Schottky diodes of opposing polarity. Key electrical parameters include a continuous forward current (IF) of 200 mA and a peak repetitive reverse voltage (VRRM) of 40 V per diode. The device operates within a junction temperature range of -65 to +150 °C. Typical forward voltage drop ranges from 0.29 V at 2.0 mA to 1.0 V at 200 mA. Reverse leakage current is typically 500 nA at 25 V. The package thermal resistance (ΘJA) is 500 °C/W.

Diode Arrays Procurement Notes

Verify the specific ordering suffix when purchasing. The provided model includes the PBFREE suffix, indicating lead-free plating. Central Semiconductor specifies that adding the TIN/LEAD suffix requests Tin/Lead plated devices. Ensure the required plating option matches the project specifications before finalizing orders to avoid compatibility issues with assembly processes or environmental regulations.

Diode Arrays Selection Notes

Select this component when a compact solution requires two isolated Schottky diodes with opposing polarities. The SOT-563 package offers space efficiency compared to discrete components. Consider the 200 mA continuous forward current rating and 40 V reverse voltage limits. The low forward voltage drop makes it suitable for low-power applications where efficiency is critical. Verify thermal constraints given the 500 °C/W thermal resistance.
