Product details
Overview
MJD32CUQ-13 from Diodes Incorporated is a 100V PNP medium-power transistor in TO252 (DPAK) package, rated for -3A continuous collector current and -100V collector-emitter breakdown voltage. It serves as a high-voltage switching or linear amplification device in automotive power supplies, motor drivers, and industrial DC-DC converters.
For engineers reviewing the MJD32CUQ-13 datasheet, MJD32CUQ-13 pinout, MJD32CUQ-13 application, or MJD32CUQ-13 equivalent, key selection criteria include VCEO = -100V, IC = -3A, VCE(sat) ≤ -700mV at -3A/-375mA, AEC-Q101 qualification, and TO252 thermal performance with RθJC = 7.3°C/W.
Technical Context
This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with verified DC current gain (hFE) of 25–50 at -1A and 10–50 at -3A under VCE = -4V. Its safe operating area supports pulsed currents up to -5A with defined thermal limits across -55°C to +150°C junction temperature range.
Designed for automotive-grade reliability, it features AEC-Q101 qualification, IATF 16949 manufacturing, and JEDEC-compliant ESD ratings (4kV HBM, 400V MM). The exposed collector pad enables low thermal resistance (RθJC = 7.3°C/W) when mounted on minimum recommended PCB copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -100 V - Maximum reverse-biased collector-emitter voltage before breakdown; defines high-side switch voltage headroom |
| IC (cont.) | -3 A - Continuous collector current rating; sets maximum steady-state load drive capability |
| VCE(sat) | -700 mV @ -3A/-375mA - Low saturation voltage ensures <2.1W conduction loss at full current |
| hFE | 10–50 - DC current gain range determines required base drive current for target collector current |
| RθJC | 7.3 °C/W - Junction-to-case thermal resistance enables direct heatsinking via exposed collector pad |
| TJ Range | -55 to +150 °C - Extended temperature operation supports under-hood automotive and industrial environments |
| ESD HBM | 4,000 V - Robust electrostatic discharge immunity simplifies handling and board-level ESD protection design |
Pinout & Package
Package: TO252 (DPAK), surface-mount, with exposed collector pad for thermal and electrical connection. Molded plastic body meets UL 94V-0 flammability rating and J-STD-020 moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main current sink terminal | Exposed metal pad - must be soldered to large copper area for thermal management and current conduction |
| Base (B) | Control input | Drives transistor into saturation or cutoff; requires current-limited drive due to hFE-dependent gain |
| Emitter (E) | Current source reference | Connected to higher potential rail in high-side switch configurations; defines common return path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS power stages |
| TO252 thermal performance | RθJC = 7.3°C/W enables >2W dissipation with minimal heatsink in compact layouts |
| High BVCEO | -100V rating supports 48V and 60V nominal systems with margin for transients and ripple |
| Lead-free & Green | Halogen- and antimony-free compound (<900ppm Br/Cl, <1000ppm Sb); compliant with RoHS 3 and automotive change control |
| Complementary pairing | Matched with NPN MJD31CUQ for push-pull, H-bridge, and differential amplifier designs |
Applications
| Automotive Power Switching | Industrial DC-DC Converter |
|---|---|
Use Scenario: High-side load switch for 12V/24V battery-fed modules such as HVAC actuators or lighting controls. IC Role / Device Role / Timing Role: PNP transistor configured as saturated switch controlling ground-referenced loads. Use Value: -100V VCEO withstands load dump transients; -700mV VCE(sat) minimizes power loss and self-heating at 3A. | Use Scenario: Output stage in non-isolated buck converter delivering 5V/2A to microcontroller subsystems. IC Role / Device Role / Timing Role: Synchronous rectifier or pre-regulator pass element in linear or quasi-resonant topology. Use Value: RθJC = 7.3°C/W allows direct thermal coupling to PCB plane, eliminating discrete heatsink in space-constrained enclosures. |
| Motor Driver Half-Bridge | Industrial Sensor Signal Conditioning |
Use Scenario: Upper transistor in half-bridge driving brushed DC motors in factory automation equipment. IC Role / Device Role / Timing Role: High-side switch synchronized with complementary NPN lower device (MJD31CUQ). Use Value: Matched hFE and VCE(sat) characteristics ensure balanced conduction and reduced shoot-through risk during commutation. | Use Scenario: Current-source biasing and active load in precision analog front-ends for pressure or temperature sensors. IC Role / Device Role / Timing Role: Linear-mode PNP current source providing stable 1–2mA excitation current. Use Value: Tight hFE spread (10–50) and low VBE(on) variation (-950mV to -1.4V) enable predictable current regulation over temperature. |
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 |
|---|---|---|---|
| MMBT3906LT1G | Lower VCEO (-40V), lower IC (-200mA), SOT-23 package, no AEC-Q101 | Not suitable for >40V systems or >1A loads; limited thermal capacity | Select only for low-voltage, low-current signal switching where TO252 footprint and automotive qualification are unnecessary |
| PN3565 | VCEO = -60V, IC = -1A, TO-92 package, no AEC-Q101, higher VCE(sat) (-1.2V @ -500mA) | Lacks automotive qualification and thermal performance; unsuitable for sustained >1A operation | Use only in cost-sensitive consumer-grade linear regulators or low-power amplifiers where thermal derating is acceptable |
Compared with MJD32CUQ-13, both alternatives lack AEC-Q101 qualification, have significantly lower voltage/current ratings, and use smaller packages with inferior thermal resistance-making them unsuitable for automotive or industrial power switching where reliability, margin, and thermal management are critical.

FAQ
What is the maximum allowable junction temperature for MJD32CUQ-13?
The absolute maximum junction temperature is +150°C, with continuous operation supported across -55°C to +150°C. Derating begins above +25°C ambient per the published thermal resistance curves; at 25mm × 25mm 1oz copper, maximum power dissipation drops to 2.30W above +25°C.
Is MJD32CUQ-13 pin-compatible with MJD31CUQ?
No - MJD32CUQ-13 (PNP) and MJD31CUQ (NPN) share identical TO252 package and pinout (C-B-E), but their complementary polarity means they cannot substitute directly. They are designed for coordinated use in push-pull or half-bridge topologies, not interchange.
Does MJD32CUQ-13 require a base resistor in switching applications?
Yes - base current must be actively limited to prevent damage and ensure saturation. With hFE = 10–50 at -3A, required IB ranges from -60mA to -300mA; typical designs use 100–375mA drive with series resistor calculated from VBE(sat) ≈ -1.2V and available drive voltage.
Can MJD32CUQ-13 be used in linear amplifier mode?
Yes - its specified hFE, fT = 3.0MHz, and VCE(sat)/VBE(on) characteristics support Class-A and AB linear amplification. However, thermal design must account for continuous power dissipation; RθJC = 7.3°C/W mandates careful heatsinking or PCB copper area allocation to avoid exceeding TJ(max).
