ZTX601ASTOB

Single Bipolar Transistors Overview

The ZTX601ASTOB 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 total power dissipation of 1 W at 25°C. The device exhibits a static forward current transfer ratio (hFE) ranging from 1,000 to 100,000 depending on the gain group and operating conditions. It operates within a junction temperature range of -55°C to +200°C and utilizes an E-Line TO-92 compatible package.

Single Bipolar Transistors Feature Summary

• High DC current gain capability suitable for amplification applications
• Robust thermal performance allowing operation up to 200°C junction temperature
• Medium power handling with 1W dissipation in standard through-hole packaging

Single Bipolar Transistors Applications

• High-gain amplifier circuits
• Power switching loads
• Driver stages for relays or motors

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'ASTOB' against the manufacturer's official documentation to confirm pinout orientation and reel specifications. Ensure the component matches the required hFE gain group (A or B) as defined in the datasheet electrical characteristics table before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when high current gain and moderate voltage blocking are required in a compact form factor. Consider the derating curve for ambient temperatures exceeding 25°C to ensure safe power dissipation limits are maintained during operation.

Single Bipolar Transistors Part Context

This part belongs to the ZTX600 series of NPN Darlington transistors produced by Diodes Incorporated. The series includes variants like the ZTX600 with lower voltage ratings. These devices are designed for general-purpose medium-power applications requiring high input impedance and low drive current requirements.

Single Bipolar Transistors Replacement Considerations

Cross-reference with other ZTX601 variants such as ZTX601BSTZ or ZTX601ASMTA for package differences. Verify that substitute parts maintain the same 160V VCEO rating and 1A Ic specification.
