HN1B01FU-Y(L,F,T)

Overview

The HN1B01FU-Y(L,F,T) is a PNP bias resistor built-in transistor (BRT) manufactured by Toshiba Semiconductor and Storage. It integrates a single PNP bipolar junction transistor with an internal biasing resistor network within a compact US-6 surface-mount package. The device is designed for general-purpose switching applications, offering simplified circuit design by eliminating external base resistors. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V, a maximum DC collector current (IC) of 150 mA, and a power dissipation (Pd) of 200 mW. The unit operates within a temperature range of -40°C to +125°C and complies with RoHS standards.

Feature Summary

• Integrates a PNP transistor with a built-in bias resistor network to reduce component count and board space.
• Provides consistent hFE characteristics due to the matched internal resistor configuration.
• Designed for high-density surface-mount assembly in a small US-6 package.

Applications

• General-purpose signal switching circuits
• Driver stages for logic interfaces
• Low-power switching applications in consumer electronics

Procurement Notes

Verify the specific suffix (L, F, or T) against the required reel quantity and packaging format before ordering. Confirm that the requested variant matches the intended RoHS compliance status and lead time requirements. Ensure the distributor source provides valid traceability documentation for the semiconductor batch. Cross-reference the part number with the manufacturer's latest datasheet to confirm active status and any potential obsolescence notices.

Selection Notes

Select this component when a PNP switching solution with integrated base biasing is required to simplify schematic design. Verify that the 50 V collector-emitter voltage rating exceeds the maximum circuit voltage. Ensure the 150 mA collector current capability meets the load requirements. Consider the US-6 package dimensions for PCB layout constraints. Compare internal resistance values if specific base drive currents are critical to the application timing.

Part Context

This component belongs to Toshiba's series of Bias Resistor Built-In Transistors (BRTs). These devices combine a single transistor with one or more resistors to facilitate easy interfacing with digital logic outputs. The HN1B01FU variant specifically utilizes a PNP configuration, serving as the complementary counterpart to NPN BRT models in dual-supply or push-pull driver configurations.

Replacement Considerations

Direct pin-to-pin replacements should be verified against the official Toshiba cross-reference list. Alternative suppliers may offer functionally equivalent PNP BRTs in US-6 packages, but internal resistor values and hFE ranges must be compared to ensure circuit compatibility. No specific substitute part numbers are confirmed in the provided public data.
