Product details

Overview

FMMT560QTA from Diodes Incorporated is a PNP bipolar junction transistor (BJT) rated for -500V collector-emitter voltage, -150mA continuous collector current, and AEC-Q101 qualified for automotive high-voltage switching applications such as ignition control and ECU load management.

For engineers reviewing the FMMT560QTA datasheet, FMMT560QTA pinout, FMMT560QTA application, or FMMT560QTA equivalent, key selection criteria include its -500V BV_CEO, SOT23 package thermal resistance (R_θJA = 250°C/W), hFE ≥100 at -1mA, V_CE(sat) ≤ -500mV at -50mA/-10mA, and IATF16949 manufacturing compliance.

Technical Context

This PNP BJT operates in linear or saturated switching mode with guaranteed breakdown at -500V across both collector-base and collector-emitter terminals. Its hFE remains stable up to -100mA, supporting precise current amplification in feedback-controlled high-voltage circuits.

V_CE(sat) of -200mV at -20mA/-2mA and -500mV at -50mA/-10mA enables low-loss switching in automotive power stages. The device's f_T of 60MHz supports fast turn-on (t_on = 110ns) and controlled turn-off (t_off = 1.5µs) under -100V V_CE conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Breakdown Voltage V_CEO	-500V - supports direct interface with 400V DC bus systems without external snubbing
Continuous Collector Current	-150mA - sufficient for driving automotive solenoids, fuel injectors, and relay coils
Peak Pulse Current I_CM	-500mA - handles short-duration inductive kickback surges in ignition circuits
DC Current Gain h_FE	100–300 - ensures reliable base drive margin across -1mA to -100mA operating range
V_CE(sat)	-500mV @ -50mA/-10mA - limits conduction loss to <25mW in saturated switch operation
Transition Frequency f_T	60MHz - enables use in high-speed PWM-driven loads up to ~5MHz fundamental frequency
ESD HBM Rating	4000V - meets automotive assembly line ESD robustness requirements per JESD22-A114

Pinout & Package

Package: SOT23 - surface-mount plastic case (UL 94V-0), 0.008g weight, moisture sensitivity level 1, matte tin-plated leads.

Pin/Terminal	Circuit Role	Design Meaning
E (Emitter)	Current source terminal	Connected to positive rail in high-side switch configuration; sets reference for base bias
B (Base)	Control input	Receives negative current to enable conduction; requires current-limiting resistor in series
C (Collector)	Switched output	Drives inductive load to ground; must observe creepage/clearance per HV design guidelines

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive temperature cycling (-55°C to +150°C), vibration, and lifetime reliability
Lead-free & halogen-free	Complies with RoHS 3 (2015/863/EU) and "Green" definition (<900ppm Br/Cl, <1000ppm Sb)
High V_CEO with low V_CE(sat)	Enables compact high-voltage switching without trade-off between blocking capability and conduction loss
Stable hFE up to -100mA	Reduces need for gain-compensating feedback in analog amplifier or linear regulator designs
SOT23 thermal performance	R_θJL = 194°C/W enables 500mW dissipation with minimal PCB copper area (15mm × 15mm 1oz)

Applications

Automotive Ignition Control

Industrial HV Power Switching

Use Scenario: High-voltage pulse generation for spark plug firing in gasoline engine ECUs.

IC Role / Device Role / Timing Role: PNP high-side switch controlling primary coil current; turns off rapidly to induce secondary voltage spike.

Use Value: -500V BV_CEO withstands flyback transients; 1.5µs t_off ensures precise spark timing control.

Use Scenario: Solid-state replacement for mechanical relays in 24–48V industrial control panels.

IC Role / Device Role / Timing Role: Load switch isolating downstream 400V-capable subsystems during fault conditions.

Use Value: -150mA I_C supports typical PLC output module loads; R_θJA = 250°C/W allows operation without heatsink.

Automotive Fuel Injector Driver

Medical HV Bias Supply

Use Scenario: Driving low-impedance fuel injector coils requiring fast current rise/fall.

IC Role / Device Role / Timing Role: Saturated PNP switch enabling precise PWM duty cycle control of injection duration.

Use Value: V_CE(sat) ≤ -500mV minimizes power loss during 10–20ms on-time; hFE ≥100 ensures stable base drive.

Use Scenario: Regulated bias supply for photomultiplier tubes or ionization sensors.

Use Value: Stable hFE up to -100mA enables accurate current mirroring; -500V rating avoids cascaded stage design.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP high-voltage switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZTX653	V_CEO = -300V, hFE = 100–300, SOT23 package	Limited to ≤300V systems; lower surge margin for ignition transients	Select when cost sensitivity outweighs 200V headroom requirement
MMBT560	V_CEO = -500V but not AEC-Q101 qualified; hFE min = 60	Not approved for automotive production; suitable only for industrial prototypes	Choose only for non-automotive designs where qualification is not mandated

Compared with ZTX653 and MMBT560, FMMT560QTA uniquely combines AEC-Q101 qualification, -500V rating, and guaranteed hFE ≥100 at -100mA-making it the sole option for production automotive high-voltage switching where reliability and specification margin are non-negotiable.

FAQ

What is the maximum safe operating voltage for FMMT560QTA in continuous DC applications?

The absolute maximum collector-emitter voltage (V_CEO) is -500V at T_A = +25°C. Derating applies above +25°C: linear reduction to -375V at +125°C per the datasheet derating curve. For continuous DC use, design must maintain ≥20% margin below rated V_CEO to ensure long-term reliability under voltage transients.

Does FMMT560QTA require a heatsink in standard SOT23 PCB layout?

No heatsink is required for ≤300mW power dissipation. With R_θJA = 250°C/W on a 15mm × 15mm 1oz FR4 copper pad, junction temperature rise is ≤75°C at 300mW-well within the -55°C to +150°C operating range. Thermal simulation is recommended if ambient exceeds +85°C or copper area is reduced.

How does the AEC-Q101 qualification impact FMMT560QTA's use in non-automotive applications?

AEC-Q101 qualification confirms enhanced robustness-including extended temperature cycling, mechanical shock, and HTOL testing-but does not restrict usage. In industrial or medical applications, it provides proven reliability margin and simplifies qualification effort, though PPAP documentation and change control processes apply only to automotive customers.

Can FMMT560QTA be used in linear amplifier configurations?

Yes-its hFE stability (100–300) across -1mA to -100mA and low V_CE(sat) support Class-A or AB linear operation. However, power dissipation must remain ≤500mW with appropriate derating; thermal design is critical due to SOT23's limited heat-spreading capability in analog bias conditions.
