Single Bipolar Transistors datasheet and documents for MPSA44BK

MPSA44BK

Single Bipolar Transistors Overview

The MPSA44BK is a high-voltage NPN silicon small-signal transistor manufactured by Diotec Semiconductor. It features a collector-emitter voltage of 400 V and a maximum DC collector current of 300 mA. The device operates within a junction temperature range of -55°C to +150°C with a total power dissipation of 625 mW. It utilizes a TO-92 bulk package with a 1.27 mm lead pitch, indicated by the BK suffix. The component provides a minimum DC current gain (hFE) of 40 and a gain-bandwidth product exceeding 50 MHz.

Single Bipolar Transistors Feature Summary

High collector-emitter voltage capability for demanding switching applications
Bulk packaging configuration with specific lead spacing for through-hole mounting
Compliance with RoHS directives and REACH regulations without exemptions

Single Bipolar Transistors Applications

Signal processing circuits
Electronic switching systems
Amplification stages

Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix 'BK' corresponds to the bulk packaging variant with a 1.27 mm lead pitch rather than the standard ammo-pack format. Confirm compliance requirements against specific project standards, noting that standard versions are commercial/industrial grade while AEC-Q101 variants require distinct suffixes. Ensure thermal management aligns with the specified 625 mW dissipation limit under operating conditions.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage NPN transistor is required for signal processing or amplification tasks. The MPSA44 offers superior voltage handling compared to lower-rated counterparts. Verify that the 300 mA current rating meets circuit demands. Consider the TO-92 form factor for space-constrained through-hole designs requiring robust mechanical stability in industrial environments.

Single Bipolar Transistors Part Context

This part belongs to the MPSA series of high-voltage NPN transistors produced by Diotec Semiconductor. The MPSA44 variant specifically targets applications requiring higher voltage tolerance than the MPSA42. The series is designed for general-purpose use in commercial and industrial electronics, providing reliable performance across a wide temperature range.
