DTA043ZEBTL

Overview

The DTA043ZEBTL is a pre-biased PNP digital transistor manufactured by ROHM Semiconductor. It integrates a single bipolar junction transistor with two internal bias resistors (R1 and R2) in a compact surface-mount package. Key electrical specifications include a collector-emitter voltage (VCEO) of -50 V, a continuous collector current (Ic) of -100 mA, and a maximum power dissipation (Pd) of 150 mW. The device features a DC current gain (hFE) of at least 80 at Ic=5mA and Vce=-10V, with a transition frequency (fT) of 250 MHz. Internal resistor values are typically 4.7 kΩ for R1 and 47 kΩ for R2. It operates within a temperature range of -55°C to +150°C and is housed in an EMT3F (SOT-416FL) package.

Feature Summary

• Integrates a PNP transistor with built-in bias resistors to simplify circuit design and reduce component count.
• Provides high-speed switching capabilities with a transition frequency of 250 MHz.
• Offers robust thermal performance with an operating junction temperature up to 150°C.
• Utilizes a compact SMD package suitable for space-constrained applications.

Applications

• General-purpose switching circuits in consumer electronics.
• Driver stages for relays, solenoids, or small motors.
• Logic level translation and interface buffering between microcontrollers and peripheral devices.
• Gate driving applications for power MOSFETs or IGBTs.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and tape/reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as supply chain conditions may vary. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required for simplified PCB layout. Compare the internal resistor ratios (R1/R2) against the target logic levels and drive requirements. Verify that the -50V voltage rating and -100mA current capacity exceed the application's peak operational demands. Consider the SOT-416FL footprint compatibility during the mechanical design phase.

Part Context

This part belongs to ROHM's DTA043 series of digital transistors, which are designed to replace discrete resistor-transistor networks. The series offers various polarity options (NPN/PNP) and resistor combinations. The DTA043ZEBTL specifically denotes the PNP variant with standard resistor values in the EMT3F package, widely used in industrial and consumer control systems.

Replacement Considerations

Direct pin-compatible substitutes within the same family include DTA043ZUBTL (different resistor values). For alternative packages, verify electrical equivalence carefully. Cross-reference with other manufacturers' PNP digital transistors only if pinout, voltage ratings, and current gains match exactly.
