ZTX601ASTOA

Single Bipolar Transistors Overview

The ZTX601ASTOA is an NPN silicon planar medium power Darlington transistor manufactured by Diodes Incorporated. It features a collector-emitter breakdown voltage of 160 V and supports a continuous collector current of 1 A with a peak pulse current capability of 4 A. The device provides a static forward current transfer ratio (hFE) ranging from 1,000 to 100,000 depending on the gain group and operating conditions. Power dissipation is rated at 1 W at 25°C ambient temperature, derating by 5.7 mW/°C above this threshold. The component operates within a junction temperature range of -55°C to +200°C and utilizes a TO-92 compatible E-Line package.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official documentation to confirm pinout orientation and gain binning requirements. Ensure the ordering code matches the exact package style and marking specifications defined in the latest datasheet revision. Cross-reference the part number with authorized distributors to confirm availability and authenticity before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when circuit designs require high current gain combined with moderate voltage blocking capabilities. The wide hFE range allows flexibility in base drive resistor calculations. Consider the 1 W power dissipation limit and thermal derating characteristics for heat management in enclosed environments. Verify that the TO-92 compatible package fits the available PCB footprint constraints.

Single Bipolar Transistors Part Context

This device belongs to the ZTX600 series of NPN silicon planar medium power Darlington transistors produced by Diodes Incorporated. The series is designed for general-purpose switching and amplification tasks. The ZTX601 variant specifically offers a higher collector-emitter voltage rating compared to the ZTX600 model while maintaining similar current handling capabilities.

Single Bipolar Transistors Replacement Considerations

Consult the official datasheet for direct pin-compatible substitutes within the same family. Verify electrical parameters such as V(BR)CEO and hFE ranges match the original design requirements before substituting.
