Product details
Overview
MJD41CQ-13 from Diodes Incorporated is a 100V NPN medium-power transistor in TO252 (DPAK) package, rated for 6A continuous collector current and 10A peak pulse current, with VCEO = 100V, VCBO = 120V, and VEBO = 7V; it serves as a robust switching or linear amplification device in automotive power supplies, motor drivers, and industrial DC-DC converters.
For engineers reviewing the MJD41CQ-13 datasheet, MJD41CQ-13 pinout, MJD41CQ-13 application, or MJD41CQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, 2.7W power dissipation at 25mm × 25mm 2oz copper layout, 1.5V VCE(sat) @ 6A/600mA, thermal resistance of 46°C/W (RθJA), and complementary pairing with MJD42CQ.
Technical Context
This NPN bipolar junction transistor operates with fixed-current gain (hFE = 30–150 at IC = 0.3A–3A, VCE = 4V) and exhibits low saturation voltage (1.5V max @ IC = 6A, IB = 600mA), enabling efficient switching in medium-power loads. Its safe operating area supports DC to 100ms pulses up to 100V/6A under defined PCB thermal conditions.
The device features ESD robustness (4kV HBM, 400V MM), RoHS-compliant matte tin-plated leads, and is qualified per AEC-Q101 with PPAP capability-ensuring suitability for automotive-grade power control circuits where reliability under thermal stress and transient load conditions is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - Maximum collector-emitter voltage before breakdown; defines upper limit for DC bus or flyback clamp applications. |
| IC (cont.) | 6 A - Continuous collector current rating; determines usable load capacity without forced cooling on 25mm × 25mm 2oz copper PCB. |
| VCE(sat) | 1.5 V max @ 6A/600mA - Low saturation voltage reduces conduction loss and heat generation in switching mode. |
| RθJA | 46 °C/W - Junction-to-ambient thermal resistance with optimized 2oz copper pad; enables ~2.7W steady-state power dissipation at +25°C ambient. |
| fT | 3 MHz - Current gain-bandwidth product; suitable for audio-frequency amplification and <100kHz PWM switching, not RF. |
| ESD HBM | 4000 V - Human Body Model rating ensures handling robustness during assembly without special ESD precautions beyond standard practices. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, with exposed collector pad for thermal conduction. Molded green plastic housing (UL 94V-0), 0.34g weight, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main current sink terminal | Exposed metal pad on underside - must be soldered to large copper area for thermal management and electrical connection. |
| Emitter (E) | Current return path | Low-inductance, high-current return node; connects directly to ground or low-side switch reference. |
| Base (B) | Control input | Drives transistor into saturation or cutoff; requires ≥600mA drive for full 6A conduction with minimal VCE(sat). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive power modules requiring PPAP documentation and IATF16949 manufacturing traceability. |
| Green compound & lead-free finish | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb); compliant with EU RoHS 2015/863/EU. |
| High BVCBO | 120 V rating allows use in 48V–72V systems with margin against transients and inductive kickback. |
| Complementary PNP pair | MJD42CQ shares identical TO252 footprint and thermal profile, enabling matched push-pull or H-bridge designs. |
Applications
| Automotive Power Supply | Industrial Motor Driver |
|---|---|
Use Scenario: 12V/24V DC-DC converter output stage regulating battery-fed loads in engine control units. IC Role / Device Role / Timing Role: NPN switch controlling high-side or low-side power delivery with fast turn-on/turn-off (td = 50ns, tf = 65ns). Use Value: 100V VCEO withstands load-dump transients up to 120V; 6A IC supports >70W output with <1.5V dropout. |
Use Scenario: Half-bridge leg in brushed DC motor driver for HVAC actuators or seat positioners. IC Role / Device Role / Timing Role: Medium-power switching element handling bidirectional current up to 6A with controlled saturation. Use Value: Matched thermal behavior with MJD42CQ enables balanced conduction losses; TO252 pad improves heatsinking over TO220 in space-constrained modules. |
| LED Driver Circuit | Power Amplifier Stage |
Use Scenario: Constant-current LED string driver in commercial lighting fixtures with 36V–48V input rails. IC Role / Device Role / Timing Role: Linear or PWM-controlled current sink regulating up to 6A through high-brightness LED arrays. Use Value: Low VCE(sat) minimizes power loss and thermal rise at full current; 150°C max TJ supports sealed enclosure operation. |
Use Scenario: Output stage in Class AB audio amplifier for vehicle infotainment subwoofers. IC Role / Device Role / Timing Role: High-current emitter-follower or common-emitter amplifier delivering low-distortion analog signals. Use Value: fT = 3MHz and hFE stability across temperature ensure bandwidth and linearity up to 20kHz; VBE(on) ≤ 2V simplifies bias network design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP16NF06L | 60V VDS, 16A MOSFET (logic-level gate), RDS(on) = 0.05Ω - lower conduction loss but no inherent current gain or linear mode stability. | Replaces BJT only in fully digital-switching topologies; unsuitable for analog amplification or precise current regulation. | Select when gate drive is 3.3V/5V logic-compatible and efficiency at light loads matters more than thermal runaway immunity. |
| MJD122G | 100V VCEO, 8A IC, TO220 package - higher current rating but larger footprint and worse thermal resistance (RθJA ≈ 65°C/W). | Used in legacy through-hole designs; lacks AEC-Q101 qualification and green compound compliance. | Choose only for cost-sensitive non-automotive applications where board space permits TO220 and PPAP is unnecessary. |
Compared with STP16NF06L and MJD122G, the MJD41CQ-13 delivers optimal balance of automotive qualification, surface-mount compactness, and bipolar linearity-making it preferred for thermally constrained, safety-critical switching and amplification where gate-drive complexity or thermal derating must be minimized.

FAQ
Is MJD41CQ-13 pin-compatible with MJD42CQ?
No-MJD41CQ is NPN and MJD42CQ is PNP; they share identical TO252 pinout (C-E-B) but opposite polarity. Their complementary pairing enables push-pull or H-bridge configurations without footprint redesign, though base drive polarity must be inverted for the PNP device.
What is the minimum recommended pad layout for MJD41CQ-13?
The minimum recommended pad (MRP) layout is defined in Diodes' package outline document DS44727, with thermal pad dimensions matching the exposed collector (C) area: 5.33mm × 4.57mm. Using this layout yields RθJA = 83°C/W; doubling copper area to 25mm × 25mm 2oz reduces it to 46°C/W.
Does MJD41CQ-13 support linear (analog) operation?
Yes-its specified VCE(sat), hFE, and SOA curves support linear-mode use. At IC = 3A and VCE = 4V, hFE = 150; however, power dissipation must remain within derated limits (e.g., ≤1.5W at +85°C ambient) to avoid thermal runaway.
Can MJD41CQ-13 replace older MJD41CT devices?
Yes-MJD41CQ supersedes MJD41CT with identical electrical specs and TO252 package, plus added AEC-Q101 qualification, green compound, and RoHS 3 compliance. No circuit or layout changes are required, but PPAP documentation is available for automotive programs.
