Overview
The DTC143ZE3HZGTL is an NPN digital transistor from ROHM Semiconductor, housed in a SOT-416 (EMT3) surface-mount package. It integrates bias resistors with R1 at 4.7 kΩ and R2 at 47 kΩ. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, continuous collector current of 100 mA, and power dissipation of 150 mW. The device features a minimum DC current gain (hFE) of 80 at 10 mA and 5 V, with a maximum operating frequency of 250 MHz. It operates within a temperature range of -55°C to +150°C and meets AEC-Q101 automotive grade standards.
Feature Summary
- Integrates dual bias resistors (R1=4.7kΩ, R2=47kΩ) for simplified circuit design
- Qualified to AEC-Q101 automotive reliability standards
- High switching speed with 250 MHz transition frequency
- Compact SOT-416 surface-mount packaging
Applications
- Automotive interface circuits
- Inverter logic applications
- Driver circuits requiring built-in biasing
Procurement Notes
Verify the specific suffix HZGTL against official ROHM documentation to confirm automotive qualification status and tape-and-reel specifications. Ensure compatibility with SOT-416 footprint requirements during PCB layout. Confirm RoHS compliance details through the manufacturer's latest environmental declaration before finalizing procurement orders.
Selection Notes
Select this component when an NPN digital transistor with unequal bias resistor ratios (R1/R2 = 1:10) is required. It serves as a direct replacement for standard DTC143ZE variants where automotive-grade reliability is mandated. Consider the 50V rating and 100mA current capacity for low-power switching tasks in constrained spaces.
Part Context
This part belongs to the DTC143 series of bias-resistor-built-in transistors. The ZE variant specifically denotes the NPN polarity with distinct internal resistor values. The HZG suffix indicates automotive-grade processing and specific packaging configurations compliant with AEC-Q101 standards, distinguishing it from commercial-grade equivalents.
Replacement Considerations
DTC143ZE3HZGT is the base part number without reel specification. DTC143ZE3 is the non-automotive equivalent. Verify pinout compatibility with SOT-416/SC-75A packages when substituting.
