DTA143ZE3HZGTL

Overview

The DTA143ZE3HZGTL is a PNP digital transistor from ROHM Semiconductor, housed in an SOT-416 (EMT3) surface-mount package. It features built-in biasing resistors with R1 at 4.7 kΩ and R2 at 47 kΩ, classified as the leak absorption type where R1 differs from R2. Key electrical parameters include a maximum collector-emitter voltage of -50 V, continuous collector current of -100 mA, and power dissipation of 150 mW. The device offers a minimum DC current gain (hFE) of 80 at -10 mA and -5 V, with a transition frequency up to 250 MHz. It operates within a storage temperature range of -55°C to +150°C and complies with AEC-Q101 automotive standards.

Feature Summary

• Integrates bias resistors to simplify circuit design by eliminating external input components for inverter configurations.
• Leak absorption resistor configuration reduces leakage current effects for stable switching performance.
• Automotive-grade reliability certified under AEC-Q101 standards for high-temperature operation.

Applications

• Inverter circuits requiring simplified input biasing without external resistors.
• Automotive electronic systems demanding high reliability and thermal stability.
• General-purpose switching applications in consumer and industrial electronics.

Procurement Notes

Verify the specific suffix HZGTL against official ROHM documentation to confirm packaging details such as tape and reel specifications. Ensure compatibility with AEC-Q101 requirements if used in automotive contexts. Cross-reference the part number with authorized distributors to confirm availability and lead times. Validate that the SOT-416 footprint matches the target PCB design constraints. Confirm RoHS compliance status through the manufacturer's latest environmental reports.

Selection Notes

Select this component when a PNP digital transistor with unequal bias resistors (R1=4.7kΩ, R2=47kΩ) is required. The SOT-416 package suits space-constrained surface-mount designs. Consider the -50V rating and -100mA current capacity for low-power switching tasks. The AEC-Q101 qualification makes it suitable for automotive environments. Compare with complementary NPN types like the DTC143 series for balanced design needs.

Part Context

This part belongs to the DTA143 series of bias resistor built-in transistors from ROHM. The ZE3 variant specifically denotes the automotive-grade version with the SOT-416 package. It complements the standard DTA143ZE3, which lacks automotive certification. The series provides integrated solutions for driving logic gates or switching loads directly from microcontroller outputs.

Replacement Considerations

The DTA143ZE3 serves as a non-automotive alternative but lacks AEC-Q101 certification. For NPN polarity, the DTC143ZE3HZGTL is the complementary counterpart. Verify pinout compatibility when substituting with other SOT-416 digital transistors from different manufacturers.
