APT27HZTR-G1

Single Bipolar Transistors Overview

The APT27HZTR-G1 is a discontinued NPN high voltage power transistor manufactured by Diodes Incorporated. It features a collector-emitter breakdown voltage (BVCEO) exceeding 450V and a collector-emitter saturation voltage (BVCES) greater than 800V. The device supports a continuous collector current of 0.8A with a maximum power dissipation of 0.8W. It is housed in a TO-92 package with joggled legs, designed for through-hole mounting. The component operates within a temperature range of -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

This component is officially marked as obsolete and discontinued by the manufacturer. Verify availability through authorized distributors or secondary markets, noting that supply may be limited or exhausted. Confirm final purchase specifications against the original datasheet DS36303 Rev. 3-4 to ensure compatibility with existing designs before acquisition.

Single Bipolar Transistors Selection Notes

Select this part only if the design requires an NPN transistor with high voltage ratings specifically suited for low-power AC-DC SMPS applications. Ensure the circuit layout accommodates the TO-92 package dimensions and thermal requirements. Consider alternative components if long-term supply continuity is required, as this specific model is no longer in production.

Single Bipolar Transistors Part Context

The APT27HZTR-G1 belongs to the APT27H series of high voltage power transistors from Diodes Incorporated. It is engineered for general-purpose switching and amplification in low-power environments. The 'Z' suffix indicates the specific tape-and-reel packaging format with joggled legs, while the 'G1' denotes environmental compliance attributes.

Single Bipolar Transistors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. As the part is obsolete, engineers must evaluate equivalent high-voltage NPN transistors from other manufacturers or newer generations within the same product family based on electrical parameter matching.
