Product details
Overview
MMBT2907AT-7-F from Diodes Incorporated is a PNP small-signal surface-mount transistor in SOT-523 package, rated for VCEO = −60 V, IC = −600 mA, PD = 150 mW, and fT = 200 MHz. It operates from −55 °C to +150 °C and serves as a general-purpose switching or linear amplification device in space-constrained DC-DC bias networks and low-power logic interfaces.
For engineers reviewing the MMBT2907AT-7-F datasheet, MMBT2907AT-7-F pinout, MMBT2907AT-7-F application, or MMBT2907AT-7-F equivalent, key selection criteria include verified PNP saturation performance at IC = −500 mA, hFE stability across −55 °C to +150 °C, and lead-free SOT-523 thermal resistance (RJA = 833 °C/W) under JEDEC-standard PCB layout.
Technical Context
This PNP bipolar junction transistor uses epitaxial planar die construction for consistent gain and breakdown behavior. Its complementary NPN counterpart is the MMBT2222AT, enabling matched pair design in differential or push-pull configurations.
Electrical operation is characterized by V(BR)CEO = −60 V at IC = −10 mA, VCE(SAT) ≤ −1.6 V at IC = −500 mA / IB = −50 mA, and Cobo = 8.0 pF at VCB = −10 V - parameters validated under standard 25 °C test conditions per DS30269 Rev. 3-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −60 V: Maximum allowable collector-emitter voltage before avalanche conduction in common-emitter configuration. |
| IC (cont.) | −600 mA: Continuous DC collector current rating at TA = 25 °C with derating above 25 °C per Fig. 1. |
| PD | 150 mW: Total package power dissipation on FR-4 PCB per AP02001 pad layout; limits usable IC×VCE product. |
| fT | 200 MHz: Current gain–bandwidth product at VCE = −20 V, IC = −50 mA; defines upper frequency limit for small-signal amplification. |
| hFE | 50–300: DC current gain range across IC = −100 µA to −500 mA; supports stable biasing in active-region amplifier stages. |
| RJA | 833 °C/W: Junction-to-ambient thermal resistance on specified PCB; determines temperature rise under steady-state power load. |
Pinout & Package
SOT-523 ultra-small surface-mount plastic package (UL 94V-0), 1.60 mm × 0.80 mm × 0.50 mm footprint, lead-free matte tin plating, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal | Current sink node in PNP configuration; connects to higher potential rail in switch applications. |
| 2 (Base) | Control terminal | Receives reverse-biased current to turn on transistor; requires external current-limiting resistor in most driver circuits. |
| 3 (Collector) | Output terminal | Current source node; delivers controlled current to load when biased in active or saturation region. |
Key Features
| Feature | Design Value |
|---|---|
| Epitaxial planar die construction | Ensures repeatable V(BR)CEO, hFE, and switching timing across production lots. |
| Complementary pairing with MMBT2222AT | Enables matched PNP/NPN implementation in differential amplifiers and H-bridge drivers without gain mismatch. |
| Lead-free matte tin finish | Meets RoHS Directive 2011/65/EU and JEDEC J-STD-020A Level 1 moisture sensitivity requirements. |
| Ultra-small SOT-523 footprint | Reduces board area by >50% vs. SOT-23; suitable for wearables, hearing aids, and compact sensor modules. |
Applications
| LED Driver Circuit | Low-Voltage Logic Interface |
|---|---|
Use Scenario: Driving red/green indicator LEDs from 3.3 V microcontroller GPIO pins with current limiting. IC Role / Device Role / Timing Role: PNP switch controlling LED anode connection to VCC; base driven by inverted logic signal. Use Value: VCE(SAT) ≤ −0.4 V at IC = −150 mA ensures < 0.2 V dropout across transistor, maximizing LED forward voltage margin. | Use Scenario: Level-shifting 1.8 V CMOS output to enable 5 V analog switch control. IC Role / Device Role / Timing Role: Active-low level translator using emitter-follower or common-emitter inversion. Use Value: hFE ≥ 75 at IC = −100 µA guarantees reliable turn-on with minimal base drive current from low-power logic. |
| DC-DC Converter Bias Network | Thermal Sensor Signal Conditioning |
Use Scenario: Providing startup bias current to primary-side controller IC in isolated flyback converters. IC Role / Device Role / Timing Role: Constant-current source in feedback path; operates in linear region for precise current mirroring. Use Value: Stable hFE over −55 °C to +150 °C maintains bias accuracy across full industrial temperature range. | Use Scenario: Amplifying low-level output from silicon bandgap temperature sensors (e.g., TMP35). IC Role / Device Role / Timing Role: Small-signal common-emitter amplifier stage with fixed-gain bias network. Use Value: fT = 200 MHz exceeds required bandwidth for DC–10 kHz sensor signal amplification with margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP small-signal transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT2907AL-7-F | SOT-23 package (3.0 mm × 1.4 mm); RJA = 300 °C/W; IC = −600 mA same rating. | Higher power handling due to lower thermal resistance; requires larger PCB area. | Select when thermal budget is constrained but board space allows SOT-23. |
| DXT2907AP5-7 | SOT-883 package; same die, smaller footprint (1.0 mm × 0.6 mm); RJA = 1000 °C/W; identical electrical specs. | Used where ultra-miniaturization is critical and ambient temperature stays below 85 °C. | Select only with validated thermal simulation confirming junction temperature remains < 150 °C. |
Compared with MMBT2907AL-7-F and DXT2907AP5-7, the MMBT2907AT-7-F uniquely balances ultra-compact size (SOT-523), industry-standard thermal performance (833 °C/W), and full industrial temperature support - making it optimal for high-density consumer and portable electronics where both space and reliability are non-negotiable.

FAQ
What is the maximum operating temperature for MMBT2907AT-7-F?
The MMBT2907AT-7-F is rated for junction and storage temperatures from −55 °C to +150 °C. Its thermal resistance (RJA = 833 °C/W) assumes mounting on a FR-4 PCB per AP02001 layout; actual max ambient temperature depends on power dissipation and board-level cooling.
Is MMBT2907AT-7-F pin-compatible with MMBT2907A?
No - MMBT2907AT-7-F uses the SOT-523 package (3-pin, 1.6 mm × 0.8 mm), while legacy MMBT2907A uses SOT-23 (3-pin, 3.0 mm × 1.4 mm). Pin assignments (E-B-C) are identical, but mechanical fit and thermal performance differ significantly.
Does this part support Pb-free solder reflow profiles?
Yes - MMBT2907AT-7-F features matte tin lead-free plating and is qualified for standard Pb-free reflow per IPC/JEDEC J-STD-020D, with peak temperature up to 260 °C and moisture sensitivity level 1 (unlimited floor life at ≤30 °C/60% RH).
How does hFE vary with collector current?
Per Figure 5 in DS30269 Rev. 3-2, hFE ranges from 300 at IC = −100 µA down to 50 at IC = −500 mA (VCE = −10 V, TA = 25 °C). This inverse relationship reflects typical BJT behavior and must be accounted for in precision bias designs.
