DMMT3906W-7-F-79

Overview

The DMMT3906W-7-F is a matched PNP small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction housed in a SOT-363 molded plastic case with UL 94V-0 flammability rating. The device provides a collector-base voltage of -40 V, collector-emitter voltage of -40 V, and emitter-base voltage of -5.0 V. Continuous collector current is rated at -200 mA with power dissipation of 200 mW. Thermal resistance from junction to ambient is 625 °C/W. Operating temperature ranges from -55°C to +150°C. DC current gain (hFE) varies from 30 to 300 depending on collector current. Current gain-bandwidth product is 250 MHz.

Feature Summary

Intrinsically matched PNP pair built with adjacent dies from a single wafer
Provides 2% matched tolerance for hFE, VCE(SAT), and VBE(SAT)
Small surface mount package suitable for automated assembly

Applications

General purpose switching applications requiring matched transistor pairs
Analog circuits utilizing intrinsically matched characteristics
Surface mount designs constrained by space requirements

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm lead-free plating status. Confirm that the requested part number matches the exact electrical specifications and packaging configuration required for the design. Ensure compatibility with standard SMD reflow processes.

Selection Notes

Select this component when matched transistor performance is critical for circuit accuracy. The intrinsic matching reduces the need for external trimming. Verify thermal management capabilities as power dissipation is limited to 200 mW. Consider the SOT-363 footprint constraints during PCB layout.

Part Context

This component belongs to the DMMT3906 series of matched PNP transistors. It is designed as a complementary pair within a single compact package. The device serves as a surface-mount alternative to through-hole matched transistor configurations, offering consistent electrical characteristics across manufacturing batches.
