Overview
The PDTC143EQB is a 50 V, 100 mA NPN Resistor-Equipped Transistor (RET) from Nexperia. It integrates bias resistors R1 and R2, both nominally 4.7 kΩ, into an ultra-small DFN1110D-3 (SOT8015) leadless package with side-wettable flanks. The device features a collector-emitter breakdown voltage of 50 V, a maximum output current of 100 mA, and a transition frequency of 230 MHz. Total power dissipation reaches 340 mW at 25 °C on a standard FR4 PCB. The component operates within an ambient temperature range of -55 °C to +150 °C.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count.
- Ultra-thin package height of 0.5 mm suitable for space-constrained applications.
- Side-wettable flanks facilitate Automatic Optical Inspection (AOI) of solder joints.
Applications
- Digital logic applications
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and reel specifications. Confirm that the requested part number matches the exact electrical characteristics and marking code required for the design. Cross-reference the datasheet revision date to ensure compliance with current product specifications before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN switching solution with integrated base biasing is required. The DFN1110D-3 package offers a low profile ideal for modern surface-mount assembly. Ensure the application voltage does not exceed the 50 V collector-emitter rating and that thermal management accommodates the specified power dissipation limits on the target PCB footprint.
Part Context
This device belongs to the PDTC143/114/124/144EQB series, which shares the same SOT8015 package and general electrical structure but varies in internal resistor values. The EQB suffix denotes the specific DFN1110D-3 leadless package variant with side-wettable flanks, distinguishing it from other package types within the broader RET family.
Replacement Considerations
Direct pin-compatible substitutes within the same series include PDTC114EQB, PDTC124EQB, and PDTC144EQB, provided their respective resistor values align with the circuit requirements. PNP complements such as PDTA143EQB are available for complementary logic designs.
