Diodes Incorporated MMDT2907AQ-7-F

Overview

MMDT2907AQ-7-F from Diodes Incorporated is a dual PNP small-signal transistor in SOT363 package, rated for −60 V V_CEO, −600 mA I_C, and 200 mW power dissipation, with h_FE = 100 (I_C = −1.0 mA, V_CE = −10 V), used in automotive-grade low-power switching and amplification circuits.

For engineers reviewing the MMDT2907AQ-7-F datasheet, MMDT2907AQ-7-F pinout, MMDT2907AQ-7-F application, or MMDT2907AQ-7-F equivalent, key selection factors include AEC-Q101 qualification, dual PNP topology in SOT363, V_CEO/V_CBO = −60 V, I_C = −600 mA, and f_T = 200 MHz for timing-critical switching designs.

Technical Context

This dual PNP transistor uses epitaxial planar die construction to deliver consistent gain and low saturation voltage across both elements. It supports simultaneous low-voltage switching (V_CE(sat) = −0.4 V at I_C = −150 mA, I_B = −15 mA) and high-speed operation (t_on = 45 ns, t_off = 100 ns).

Thermally, it is rated for −55°C to +150°C operation with R_θJA = 625°C/W on minimum FR-4 pad layout. Its ESD robustness (HBM = 4 kV, MM = 400 V) and halogen/antimony-free "Green" construction meet automotive reliability requirements.

FAQ

Is MMDT2907AQ-7-F pin-compatible with standard SOT363 dual transistors?

Yes - it uses the industry-standard SOT363 pinout (C1/E1/B1/C2/E2/B2) defined in JEDEC MO-178. Pin assignments match other dual PNP devices like NSVD2907AT1G and ZXTD2020Z, enabling direct PCB footprint reuse without layout changes.

What is the maximum operating temperature for continuous use?

The device is rated for continuous operation from −55°C to +150°C junction temperature. At ambient temperatures up to +85°C, full I_C = −600 mA and P_D = 200 mW are supported when mounted on minimum recommended FR-4 pad layout with 1 oz copper.

Does MMDT2907AQ-7-F require external base resistors in switching applications?

Yes - base current must be limited to prevent damage. For I_C = −150 mA with h_FE ≈ 100, minimum I_B = −1.5 mA is required; a 3.3 kΩ resistor from −5 V logic rail provides appropriate drive while staying within V_BE(sat) limits.

How does the "Q" suffix affect specifications versus MMDT2907A-7-F?

The "Q" suffix denotes automotive qualification: identical electrical and thermal specs, but with full AEC-Q101 stress testing, PPAP documentation capability, and enhanced traceability (K2F marking, automotive-specific lot controls). No performance trade-offs are introduced.
