DTC123YE3HZGTL

Overview

The DTC123YE3HZGTL is an NPN digital transistor manufactured by ROHM Semiconductor, housed in a compact SOT-416 (EMT3) surface-mount package. It integrates bias resistors with values of R1 = 2.2 kΩ and R2 = 10 kΩ to simplify circuit design. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current (Ic) of 100 mA, and a power dissipation (Pd) rating of 150 mW. The device features a minimum DC current gain (hFE) of 33 and operates within a temperature range of -55°C to +150°C. This component is qualified under the AEC-Q101 standard for automotive applications.

Feature Summary

• Integrates built-in biasing resistors (R1=2.2kΩ, R2=10kΩ) to eliminate external input components
• Qualified for automotive environments under the AEC-Q101 reliability standard
• Supports high-temperature operation up to +150°C storage and working limits

Applications

• Automotive electronic control units requiring AEC-Q101 compliant components
• Inverter circuits utilizing built-in biasing without external resistors
• Signal switching and level shifting in compact consumer electronics

Procurement Notes

Verify the specific suffix HZGTL against official ROHM documentation to confirm the exact tape-and-reel packaging configuration and lead time requirements. Ensure that the ordering quantity aligns with the manufacturer's standard packing quantity of 3000 units per reel. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards and environmental compliance regulations before finalizing procurement orders.

Selection Notes

Select this component when an NPN digital transistor with unequal bias resistors (R1≠R2) is required for space-constrained designs. The SOT-416 package offers a small footprint suitable for dense PCB layouts. Consider the 50V voltage rating and 100mA current capacity to ensure adequate headroom for the target application. Verify that the AEC-Q101 qualification meets the specific automotive grade requirements of the end product.

Part Context

This part belongs to the DTC123 series of bias resistor built-in transistors from ROHM. The 'YE3' designation typically indicates the specific resistor ratio and package type within the family. The 'HZGTL' suffix denotes the automotive-grade variant packaged in reels. It serves as a direct replacement for discrete resistor-transistor combinations, reducing board space and assembly complexity in both industrial and automotive systems.

Replacement Considerations

The DTC123YE3HZG is listed as a related part number. Verify pinout and electrical parameter equivalence before substitution. Ensure any alternative maintains the same SOT-416 package dimensions and AEC-Q101 qualification status.
