CMXSTB400 BK PBFREE

Diode Arrays Overview

The Central Semiconductor CMXSTB400 BK PBFREE is a surface mount silicon forward reference diode (stabistor) housed in an SOT-26 case. It contains four internal diodes configured for controlled forward voltage characteristics, serving as a surface mount alternative to the 1N5179 leaded device. The component operates within a junction temperature range of -65°C to +150°C and supports a maximum power dissipation of 350 mW at 25°C ambient conditions.

Diode Arrays Feature Summary

• Multi-chip silicon construction providing stable forward voltage references
• Designed for precise voltage regulation, sensing, and comparing applications
• Surface mount packaging optimized for board space efficiency

Diode Arrays Applications

• Voltage regulation circuits
• Signal sensing networks
• Voltage comparison logic

Diode Arrays Procurement Notes

Verify current availability status as this series has been transitioned to End of Life by the manufacturer. Confirm if stock-only fulfillment applies or if final shipments are restricted. Ensure ordering suffixes match required plating specifications, such as PBFREE or TIN/LEAD, when requesting quotes from authorized distributors.

Diode Arrays Selection Notes

Select this component when a surface mount stabistor with specific forward voltage tolerances is required. Verify that the SOT-26 package dimensions align with the PCB layout. Consider the internal pin configuration where Pin 1 serves as Anode D1 and Pin 3 acts as Cathode D2 for testing purposes between pins.

Diode Arrays Part Context

This part belongs to the CMXSTB200 Series family of surface mount silicon forward reference diodes. The series includes variants like the CMXSTB200 and CMXSTB300, which offer different forward voltage ranges while sharing the same SOT-26 mechanical outline and multi-chip architecture designed for compact circuit integration.
