DST3906DJ-7

Overview

The DST3906DJ-7 is a dual PNP surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and operates within a collector-emitter voltage (VCEO) of -40 V and a continuous collector current (IC) of -200 mA. The device dissipates up to 300 mW of power with a thermal resistance (RθJA) of 417 °C/W. Electrical characteristics include a DC current gain (hFE) ranging from 60 to 300 depending on the collector current, and a current gain-bandwidth product (fT) of 300 MHz. The component is housed in an SOT963 package and supports an operating temperature range from -55°C to +150°C.

Feature Summary

• Dual PNP configuration utilizing epitaxial planar die construction for reliable switching performance.
• Ultra-small SOT963 package designed to facilitate automated assembly processes.
• Fully RoHS compliant and halogen/antimony-free green device construction.

Applications

• General-purpose signal switching circuits
• Low-power amplifier stages
• Automated assembly compatible logic interfaces

Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the tape and reel packaging format containing 10,000 units per reel. Confirm that the SOT963 package dimensions align with the target PCB land pattern requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact dual PNP solution is required for low-voltage applications. Ensure the design accommodates the 300 mW power dissipation limit and verify that the -40 V breakdown voltage meets the circuit's maximum operational stress conditions.

Part Context

This part belongs to the DST3906 series of dual transistors produced by Diodes Incorporated. It serves as a compact alternative to discrete single transistors in space-constrained designs, offering matched electrical characteristics between the two internal PNP elements within the SOT963 footprint.

Replacement Considerations

Direct substitutes must match the SOT963 package and dual PNP configuration. Verify pinout compatibility and ensure replacement parts meet or exceed the -40 V VCEO and -200 mA IC ratings specified in the datasheet.
