DTB523YE3TL

Overview

The DTB523YE3TL is a PNP digital transistor manufactured by Rohm Semiconductor, housed in an SOT-416 (EMT3) surface-mount package. It integrates bias resistors to simplify circuit design. Key electrical specifications include a collector current of -0.1 A and a supply voltage of -50 V. The internal resistor configuration consists of an input resistance (R1) of 2.2 kΩ and an emitter-base resistance (R2) of 10 kΩ. The device features a power dissipation rating of 0.15 W and a minimum DC current gain (hFE) of 33. It operates within a storage temperature range of -55°C to 150°C.

Feature Summary

• Integrates built-in biasing resistors to enable inverter circuit configuration without external input components.

Applications

• General-purpose switching applications requiring compact digital logic interfaces.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives if required by the target assembly process. Confirm availability status directly with authorized distributors as stock levels fluctuate. Cross-reference the JEITA package code SC-75A for footprint verification during PCB layout design.

Selection Notes

Select this component when a PNP digital transistor with R1=2.2kΩ and R2=10kΩ is required in an SOT-416 package. Compare hFE requirements against the minimum specification of 33. Evaluate thermal constraints based on the 0.15 W power dissipation limit. Consider alternative packages like SOT-723 if smaller footprints are needed for high-density designs.

Part Context

This part belongs to Rohm's standard digital transistor series, which combines transistors with integrated bias resistors. These devices replace multiple discrete components, reducing board space and assembly costs. The SOT-416 package offers a balance between thermal performance and size for general consumer electronics.

Replacement Considerations

The DTC123YUB is listed as a similar NPN specification but differs in polarity. For direct PNP replacement, verify equivalent resistor values and package dimensions. No identical public substitute is confirmed in the provided data; consult the manufacturer for qualified alternatives.
