SMBT1565LT1

Single Diodes Overview

The SMBT1565LT1 is a high-voltage special purpose NPN transistor manufactured by onsemi. It is housed in an SOT-23 surface-mount package and is designed for switching and amplification applications. The device features a collector-emitter voltage rating of 65 V and supports a continuous collector current of 100 mA. With a maximum power dissipation of 300 mW, it operates within a temperature range of -55°C to +150°C. The component exhibits a DC current gain (hFE) minimum of 220 and a maximum operating frequency of 100 MHz, making it suitable for general-purpose digital transistor tasks requiring high voltage tolerance.

• Digital logic interface buffers

Single Diodes Procurement Notes

Verify the specific ordering suffix LT1G or similar variants against the official onsemi datasheet to ensure compatibility with required tape-and-reel quantities and RoHS compliance status. Confirm that the SOT-23 footprint matches the target PCB design. Check for AEC-Q100 qualification if automotive reliability standards are mandated for the end application.

Single Diodes Selection Notes

Select this component when a single NPN transistor with high-voltage handling is required in a small outline package. Ensure the circuit design accounts for the 300 mW power dissipation limit at elevated temperatures. Compare hFE characteristics against load requirements to verify adequate gain for the intended switching speed and drive capabilities.

Single Diodes Part Context

This part belongs to onsemi's portfolio of special purpose transistors. It complements other small-signal devices in the BC856/BC848 series but offers distinct high-voltage specifications. The SOT-23 form factor aligns with industry-standard surface-mount assembly processes used in consumer electronics and industrial control modules.

Single Diodes Replacement Considerations

Cross-reference with equivalent high-voltage NPN SOT-23 transistors from other manufacturers such as BC847HV or BCR4xx series components. Verify pinout compatibility and thermal resistance parameters before substitution.
