DTB523YMT2L

Overview

The DTB523YMT2L is a PNP digital transistor with built-in resistors manufactured by Rohm Semiconductor. It features a collector-emitter voltage of -12 V and a continuous collector current of -0.5 A. The device includes an internal base resistor (R1) of 2.2 kOhms and an emitter-base resistor (R2) of 10 kOhms. Key electrical parameters include a DC current gain (hFE) of at least 140, a transition frequency of 260 MHz, and a maximum power dissipation of 150 mW. It is housed in the EMT3 surface-mount package.

Feature Summary

• Integrates biasing resistors to simplify circuit design
• Provides high-speed switching capabilities
• Offers compact surface-mount packaging

Applications

• General-purpose logic level shifting
• Driver circuits for small-signal loads
• Interface between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix 'T2L' against official Rohm documentation to confirm tape-and-reel quantity and marking details. Ensure compatibility with the EMT3 footprint during procurement planning. Cross-reference datasheet revisions to confirm RoHS compliance status and lead times directly from the manufacturer.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required for space-constrained designs. Verify that the -12 V rating meets system voltage requirements. Confirm that the 2.2 kOhm input resistance aligns with the driving source impedance. Check thermal constraints given the 150 mW power dissipation limit in the EMT3 package.

Part Context

This part belongs to the DTB523 series of digital transistors. It serves as the tape-and-reel variant of the DTB523YM. The series provides pre-biased solutions for PNP applications. It replaces discrete resistor networks in standard switching topologies. The EMT3 package offers a small form factor for dense PCB layouts.

Replacement Considerations

DTB523YM is the cut-tape equivalent. DTA123EM is a similar PNP type but with different voltage ratings. Verify pinout compatibility before substitution. Check if alternative packages meet spatial requirements.
