Product details
Overview
MMBTA56Q-13-F from Diodes Incorporated is a 80V PNP medium-power bipolar junction transistor in SOT23 package, rated for -500mA continuous collector current and 350mW power dissipation at 25°C ambient, with DC current gain (hFE) ≥100 at -10mA/-1.0V, used for low-power switching and amplification in automotive-compliant signal conditioning circuits.
For engineers reviewing the MMBTA56Q-13-F datasheet, MMBTA56Q-13-F pinout, MMBTA56Q-13-F application, or MMBTA56Q-13-F equivalent, key selection criteria include VCEO = -80V, IC = -500mA, hFE ≥100 @ -10mA, VCE(sat) ≤ -0.25V @ -100mA/-10mA, and automotive-grade qualification per AEC-Q101.
Technical Context
This PNP transistor employs epitaxial planar die construction for stable gain and low leakage, optimized for linear amplification and saturated switching in low-voltage analog and digital interface stages. Its -80V VCEO and -4.0V VEBO ratings support operation in 24V industrial control rails with margin against transients.
The device features a thermally enhanced SOT23 package with RθJA = 357°C/W on 15mm × 15mm 1oz copper, enabling reliable operation up to +150°C junction temperature. ESD robustness includes 4kV HBM and 400V MM ratings per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -80 V: Maximum safe collector-emitter voltage before breakdown in common-emitter configuration. |
| IC (cont.) | -500 mA: Continuous collector current rating defining maximum DC load drive capability. |
| PD @ TA=25°C | 350 mW: Power dissipation limit on 15 mm × 15 mm PCB copper area, dictating thermal derating above 25°C. |
| hFE | ≥100 @ -10 mA, -1.0 V: Minimum DC current gain ensuring predictable base drive requirements for switching. |
| VCE(sat) | ≤ -0.25 V @ -100 mA / -10 mA: Low saturation voltage enabling efficient switching with <250 mV conduction loss. |
| fT | 50 MHz: Transition frequency confirming usable bandwidth for audio and low-speed digital signal amplification. |
Pinout & Package
Package: SOT23 - surface-mount plastic package with matte tin-plated leads, moisture sensitivity level 1, UL 94V-0 rated molding compound, weight ≈ 0.008 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal | Connected to higher potential rail in PNP switching; defines reference for base bias and current flow direction. |
| 2 (Base) | Control input | Receives negative-going drive signal to turn on; requires ~1.2 V forward bias relative to emitter for saturation. |
| 3 (Collector) | Current sink terminal | Connected to load and lower-potential node; carries full switched current with minimal voltage drop in saturation. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 qualified variant (MMBTA56Q), enabling use in under-hood and chassis control modules without additional stress screening. |
| Green packaging | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb), compliant with RoHS 3 and environmental directives. |
| Thermal performance | RθJL = 350°C/W enables direct heat transfer from junction to solder point, improving reliability in high-temperature PCB layouts. |
| ESD robustness | 4 kV HBM rating reduces risk of handling damage during automated assembly and field service replacement. |
Applications
| Automotive Door Module | Industrial Sensor Interface |
|---|---|
Use Scenario: Driving LED status indicators and small solenoids in door latch and window control units. IC Role / Device Role / Timing Role: PNP switch controlling 24V loads with logic-level base drive from microcontroller GPIO. Use Value: -80V VCEO provides margin against load dump transients; -0.25V VCE(sat) minimizes power loss and self-heating in space-constrained modules. | Use Scenario: Level-shifting and buffering analog sensor outputs (e.g., RTD, thermistor) into ADC inputs. IC Role / Device Role / Timing Role: Emitter-follower amplifier providing low-output-impedance buffering without inversion. Use Value: hFE ≥100 ensures stable gain across temperature; -5.0V VEBO supports biasing in wide-supply-rail sensor front-ends. |
| Consumer Appliance Control Board | Medical Diagnostic Instrument |
Use Scenario: Controlling relay coils and indicator lamps in washing machine and HVAC control panels. IC Role / Device Role / Timing Role: Medium-power discrete switch replacing larger TO-92 devices to reduce board area. Use Value: SOT23 footprint saves >60% PCB area vs. TO-92; 350 mW PD supports sustained 200–300 mA coil drive. | Use Scenario: Isolating and amplifying low-level biopotential signals (e.g., ECG lead-off detection). IC Role / Device Role / Timing Role: Low-noise, low-leakage PNP stage in precision front-end signal conditioning. Use Value: ICEX ≤ -100 nA ensures minimal offset drift; fT = 50 MHz supports accurate pulse waveform reproduction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBTA56-7-F | Non-automotive grade; same electrical specs but not AEC-Q101 qualified. | Suitable for commercial/industrial use only; not approved for automotive safety-critical functions. | Select when cost-sensitive non-automotive designs require identical performance without qualification overhead. |
| PN2907A | TO-92 package; lower fT (≈200 kHz), higher VCE(sat) (≤ -0.5 V @ -100 mA), same VCEO (-60 V). | Larger footprint and lower speed limit use to DC/low-frequency switching only. | Choose only if legacy TO-92 layout compatibility is mandatory and thermal constraints allow larger package. |
Compared with MMBTA56Q-13-F, the MMBTA56-7-F offers identical electrical behavior without automotive qualification, while PN2907A trades SOT23 miniaturization and 50 MHz bandwidth for TO-92 mechanical compatibility and lower cost in non-space-constrained designs.

FAQ
What is the maximum operating junction temperature for MMBTA56Q-13-F?
The absolute maximum junction temperature is +150°C, with storage temperature range matching at -55°C to +150°C. Derating begins above +25°C ambient per the published thermal resistance curve (RθJA = 357°C/W on 15 mm × 15 mm copper), requiring power reduction of ~3.5 mW/°C above 25°C.
Is MMBTA56Q-13-F pin-compatible with MMBTA55Q-13-F?
Yes - both share identical SOT23 pinout (Emitter-Base-Collector on pins 1-2-3) and mechanical dimensions, but MMBTA55Q has -60V VCEO/VCEO ratings versus -80V for MMBTA56Q. They are complementary PNP types, not functional substitutes.
Does MMBTA56Q-13-F support pulsed operation beyond its DC ratings?
Yes - the datasheet specifies pulsed test conditions (≤300 µs pulse width, ≤2% duty cycle) for hFE and fT measurements. Pulse power dissipation follows the transient thermal impedance curve (Figure 3), allowing short-duration peak currents exceeding -500 mA with appropriate duty cycling.
What marking code appears on the top of the MMBTA56Q-13-F package?
The top-side marking is "K2G" followed by a two-character date code (e.g., "K9" for September 2023), consistent with Diodes' SOT23 marking standard. "K2G" identifies the MMBTA56 device type, not a batch or revision code.
