NSTB1002DXV5T1

Overview

The NSTB1002DXV5T1G is a dual complementary Bi-Transistor (BRT) featuring integrated bias resistors, housed in an SOT-553 surface-mount package. It combines a PNP transistor (Q1) and an NPN transistor (Q2) with monolithic base and base-emitter resistors into a single component. The PNP section supports a maximum collector current of -200 mA with voltage ratings of -40 V for both collector-base and collector-emitter junctions. The NPN section provides a maximum collector current of 100 mA with voltage ratings of 50 V for collector-base and collector-emitter junctions. Total device power dissipation reaches 500 mW under two-junction heating conditions at 25°C ambient temperature.

Feature Summary

• Integrates a PNP and NPN transistor with built-in biasing networks to replace discrete components
• Utilizes compact SOT-553 packaging for space-constrained low-power applications
• Simplifies circuit design by eliminating external resistor requirements

Applications

• Low-power surface mount digital switching circuits
• Space-constrained printed circuit board designs
• Complementary logic interface buffering

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm exact electrical characteristics and tape-and-reel specifications. Ensure the requested part number matches the required voltage and current ratings for the target application environment.

Selection Notes

Select this component when a complementary pair of biased transistors is required in a minimal footprint. Verify that the integrated resistor values meet the specific drive requirements for the connected logic levels and load conditions without additional external components.

Part Context

This component belongs to onsemi's BRT series, designed to simplify biasing networks in digital circuits. The SOT-553 package allows for high-density mounting, making it suitable for modern portable and industrial electronics where board real estate is limited.

Replacement Considerations

Check for direct pin-compatible substitutes within the same BRT family. Ensure any replacement maintains the same complementary configuration and integrated resistance values to preserve circuit timing and bias stability.
