Overview
The DMMT3904WQ-7-F is an automotive-grade, matched pair NPN small signal transistor manufactured by Diodes Incorporated. It features a collector-emitter voltage (VCEO) of 40 V and a continuous collector current (IC) of 200 mA. The device operates within a junction temperature range of -65°C to +150°C and dissipates up to 200 mW of power. Electrical characteristics include a DC current gain (hFE) ranging from 40 to 300, a transition frequency (fT) of 300 MHz, and a base-collector breakdown voltage (BVCBO) of 60 V. The component is housed in a SOT363 surface-mount package.
Feature Summary
- Intrinsically matched NPN transistor pair with 2% matching on current gain and 2mV matching on base-emitter voltage.
- Qualified to AEC-Q101 standards for high reliability and capable of PPAP submission.
- Fully internally isolated transistors contained within a compact SOT363 surface mount package.
Applications
- Current mirrors
- Differential and instrumentation amplifiers
- Comparators
Procurement Notes
Verify the specific ordering suffix 'Q' confirms AEC-Q101 automotive qualification status as documented in the manufacturer's ordering information table. Ensure that the required reel size and tape width specifications align with automated assembly equipment capabilities before finalizing procurement orders.
Selection Notes
Select this component when precise matching between two NPN transistors is required for analog circuit performance. The intrinsic matching eliminates the need for external trimming. Verify that the 200 mA collector current and 40 V voltage ratings meet the operational requirements of the target application design.
Part Context
This part belongs to the DMMT3904W series of matched dual NPN transistors. The standard version shares identical electrical and thermal characteristics with the Q variant, which specifically denotes automotive grade compliance. Both utilize the same SOT363 package and internal die configuration.
Replacement Considerations
Standard DMMT3904W-7-F parts are electrically equivalent but lack the formal automotive qualification documentation. Other manufacturers offer MMDT3904 variants in similar packages, though intrinsic matching tolerances may differ.
FAQ
What is the intrinsic matching tolerance for the current gain?
The datasheet specifies a 2% matching tolerance for the DC current gain (hFE) ratio between the two transistors at IC = 2mA and VCE = 5V.
How does the Q suffix affect the electrical performance?
According to the manufacturer, automotive products are electrically and thermally the same as standard products, except where explicitly specified in the datasheet.
What is the maximum operating junction temperature?
The maximum operating and storage temperature range extends up to +150°C.
