Product details
Overview
FMMT560QTC from Diodes Incorporated is a PNP bipolar junction transistor rated for -500V collector-emitter voltage, -150mA continuous collector current, and AEC-Q101 qualified for automotive use in high-voltage switching applications such as ignition systems and LED drivers.
For engineers reviewing the FMMT560QTC datasheet, FMMT560QTC pinout, FMMT560QTC application, or FMMT560QTC equivalent, key selection criteria include breakdown voltage margin, pulse current capability, hFE linearity at -100mA, thermal resistance (RθJA = 250°C/W), and SOT23 lead-free packaging compliance.
Technical Context
This PNP BJT operates with VCEO = -500V and IC = -150mA under DC conditions, supporting high-voltage off-state blocking and moderate-current switching. Its fT = 60MHz enables fast turn-on (ton = 110ns) and controlled turn-off (toff = 1.5µs) in pulsed power circuits.
The device delivers hFE = 100–300 across IC = -1mA to -100mA at VCE = -10V, with VCE(sat) ≤ -500mV at IC = -50mA/IB = -10mA. It uses a fully RoHS-compliant, halogen- and antimony-free "Green" molding compound and matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -500V - supports primary-side switching in >400V DC bus applications without derating |
| IC (continuous) | -150mA - sufficient for driving automotive solenoids or medium-power LED strings |
| ICM (pulse) | -500mA - enables short-duration surge handling in ignition coil drivers |
| hFE | 100–300 @ IC = -1mA to -100mA - ensures stable base drive design across operating range |
| VCE(sat) | ≤ -500mV @ IC = -50mA/IB = -10mA - limits conduction loss in linear or saturated switching |
| RθJA | 250°C/W - requires thermal pad or copper pour for sustained >100mA operation |
| ESD HBM | 4000V - provides robust handling during automotive PCB assembly |
Pinout & Package
Package: SOT23 - surface-mount plastic case, 0.008g weight, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal | Connected to higher potential rail; must maintain VE ≥ VC + 7V to avoid EB junction breakdown |
| 2 (Base) | Control input | Receives negative current to saturate; IB = -10mA required for full IC = -50mA switching |
| 3 (Collector) | Current sink terminal | Connected to load and high-voltage rail; handles -500V reverse bias when off |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive temperature cycling (-55°C to +150°C), vibration, and ESD stress per JESD22 |
| Lead-free & Green construction | Meets RoHS 3 (2015/863/EU); Br+Cl <1500ppm, Sb <1000ppm - supports eco-compliant manufacturing |
| High BVCEO margin | -500V rating provides ≥25% headroom over 400V automotive battery transients |
| Low VCE(sat) at high current | -500mV at IC = -50mA reduces power dissipation to ≤25mW in saturation |
| Stable hFE vs. IC | hFE remains ≥100 up to -100mA - simplifies base resistor selection across load range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZTX653 | VCEO = -300V, IC = -1A, SOT89 package, hFE = 100–300 @ -500mA | Higher current but lower voltage rating; unsuitable for >350V bus applications | Select only where bus voltage ≤300V and thermal mass permits larger SOT89 footprint |
| MMBT560 | VCEO = -400V, IC = -100mA, same SOT23 package, hFE = 60–240 @ -50mA | Lower voltage and current ratings; reduced pulse capability (ICM = -300mA) | Acceptable for cost-sensitive non-automotive 24–48V systems with relaxed transient margins |
Compared with ZTX653 and MMBT560, the FMMT560QTC uniquely combines -500V rating, AEC-Q101 qualification, and SOT23 form factor-making it the only option for space-constrained automotive HV switching where both voltage margin and qualification are mandatory.

FAQ
What is the maximum safe operating voltage for FMMT560QTC in continuous DC mode?
The absolute maximum collector-emitter voltage (VCEO) is -500V at TA = +25°C. Derating is required above +25°C: RθJA = 250°C/W implies ~2.0V/°C reduction in VCEO per °C rise in junction temperature. At +125°C junction, max safe VCEO drops to approximately -300V under steady-state conditions.
Does FMMT560QTC support pulsed operation beyond its continuous current rating?
Yes - peak pulse current (ICM) is rated at -500mA for pulses ≤300µs with ≤2% duty cycle. This enables use in ignition coil drivers and flyback snubbers where brief high-current demands occur without exceeding thermal limits.
Is the SOT23 package of FMMT560QTC compatible with standard reflow profiles?
Yes - the device is moisture sensitivity level 1 (MSL-1), meaning it can be stored indefinitely at ≤30°C/60% RH and processed using standard IPC/JEDEC J-STD-020 reflow profiles without baking. Matte tin plating ensures compatibility with lead-free soldering at peak temperatures up to 260°C.
How does the hFE variation affect base drive design across temperature?
hFE is specified at +25°C (100–300), but typical data shows ~20% reduction at -40°C and ~15% reduction at +125°C. For robust design, base current should be sized using hFE(min) = 100 at room temperature and verified at extremes using the hFE vs. IC curves in DS37020 Rev. 2, page 5.
