CMXSH-3 TR PBFREE

Diode Arrays Overview

The CMXSH-3 TR PBFREE is a surface mount silicon triple isolated Schottky diode manufactured by Central Semiconductor Corp. It contains three isolated switching diodes in an SOT-26 package with a marking code of XH3. Key electrical parameters include a peak repetitive reverse voltage (VRRM) of 30 V, continuous forward current (IF) of 100 mA, and peak forward surge current (IFSM) of 750 mA. The device operates within a junction temperature range of -65 to +150 °C. Forward voltage drop ranges from 0.29 V at 2.0 mA to 1.00 V at 100 mA, with a typical reverse leakage current of 500 nA at 25 V.

Diode Arrays Procurement Notes

Verify the specific ordering suffix when purchasing. The manufacturer specifies that adding 'PBFREE' indicates lead-free plating, while 'TIN/LEAD' denotes tin/lead plating options. Confirm the exact part number matches the required plating specification to ensure compliance with project material constraints and environmental regulations.

Diode Arrays Selection Notes

Select this component when a design requires three independent Schottky diodes in a minimal footprint. The SOT-26 package provides isolation between internal diodes, eliminating the need for external isolation components. Ensure the 30 V reverse voltage rating and 100 mA continuous current capacity align with the circuit's operational limits and thermal dissipation requirements.
