Product details
Overview
ZXT13N15DE6 from Diodes Incorporated is a 15V NPN low-saturation switching transistor in SOT26 package, rated for 5A continuous collector current and 15A peak pulse current, with RCE(SAT) = 29 mΩ and VCE(sat) ≤ 70 mV at 1 A - optimized for high-efficiency DC–DC converters and motor control power switches.
For engineers reviewing the ZXT13N15DE6 datasheet, ZXT13N15DE6 pinout, ZXT13N15DE6 application, or ZXT13N15DE6 equivalent, key selection criteria include saturation voltage at high current, thermal resistance (RθJA = 113 °C/W), AEC-Q101 qualification, and SOT26 lead-frame thermal performance in compact power-switching layouts.
Technical Context
This NPN bipolar junction transistor is engineered for low-loss switching in automotive-grade power management, featuring a 15 V VCEO, 40 V VCBO, and 7.5 V VEBO to support robust operation under transient overvoltage conditions. Its fT = 72 MHz enables fast switching in PWM-controlled topologies.
The device uses a thermally enhanced SOT26 package with direct collector-lead thermal path (RθJL = 18.6 °C/W) and operates across –55 °C to +150 °C, meeting AEC-Q101 stress test requirements for humidity, temperature cycling, and ESD (HBM = 4 kV).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 15 V - Maximum safe collector-emitter voltage during switching, defining use in ≤12 V nominal rail systems |
| IC (continuous) | 5 A - Sustained load current capability without thermal shutdown under PCB heatsinking per spec |
| VCE(sat) @ 1 A | ≤70 mV - Low conduction loss enabling <0.07 W dissipation at 1 A, critical for efficiency in battery-powered DC–DC stages |
| RCE(SAT) | 29 mΩ - Equivalent on-resistance derived from VCE(sat)/IC, used for thermal modeling and layout copper sizing |
| fT | 72 MHz - Transition frequency confirming suitability for PWM frequencies up to ~5–10 MHz with adequate gain margin |
| RθJA | 113 °C/W - Junction-to-ambient thermal resistance on 25 mm × 25 mm 1 oz Cu PCB, used to calculate max ambient temp at 5 A |
| ESD HBM | 4 kV - Human Body Model rating ensuring robustness during board assembly and handling in automotive production |
Pinout & Package
SOT26 is a 6-pin, surface-mount, thermally enhanced plastic package with exposed collector pad; pin 1 is emitter, pin 2 is base, pin 3 is collector, pin 4 is emitter, pin 5 is base, pin 6 is collector - dual-emitter/dual-base configuration supports paralleled operation or complementary pair layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (E1) | Emitter | Primary emitter terminal; electrically tied to Pin 4; used for low-impedance return path in high-current switching |
| Pin 2 (B1) | Base | Control input for first transistor section; driven by PWM controller with 100 mA max base current rating |
| Pin 3 (C1) | Collector | Main power output node; thermally connected to exposed pad; rated for 5 A continuous conduction |
| Pin 4 (E2) | Emitter | Second emitter terminal; internally connected to Pin 1; enables dual-emitter layout for current sharing |
| Pin 5 (B2) | Base | Independent base terminal for second section; allows separate drive or paralleled base connection |
| Pin 6 (C2) | Collector | Second collector node; isolated from Pin 3 but same potential when used in parallel configuration |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) at high current | 70 mV max @ 1 A ensures <70 mW conduction loss, reducing thermal load in space-constrained motor drivers |
| AEC-Q101 qualification | Validated for automotive power modules including engine control units and body electronics requiring reliability beyond industrial grade |
| Dual-collector/dual-emitter structure | Enables current sharing between two internal transistors, improving thermal distribution and derating margin at 5 A |
| SOT26 thermal lead-frame | Exposed collector pad and low RθJL = 18.6 °C/W allow direct thermal coupling to PCB copper, bypassing epoxy thermal bottleneck |
| Halogen- and antimony-free "Green" construction | Meets automotive OEM environmental mandates (<900 ppm Br/Cl, <1000 ppm Sb) without compromising solderability or long-term reliability |
Applications
| DC–DC Converters | Power Management Functions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low-saturation switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXT13N50DE6 | Higher VCEO = 50 V, higher RCE(SAT) = 45 mΩ, same SOT26 package | Better for 24–48 V industrial supplies; less efficient at 12 V due to higher saturation loss | Select when system rail exceeds 15 V and thermal budget allows ≥30% higher conduction loss |
| DMT3006LPSQ-13 | MOSFET (30 V, 6.5 mΩ), logic-level gate, no base current required | Lower drive complexity and zero gate charge, but lacks bipolar ruggedness to avalanche and ESD | Prefer for low-power, high-frequency SMPS where gate drive simplicity outweighs need for AEC-Q101 bipolar robustness |
Compared with ZXT13N15DE6, ZXT13N50DE6 trades lower saturation for higher voltage tolerance, while DMT3006LPSQ-13 replaces bipolar drive with MOSFET gate control - choice depends on whether system priority is ruggedness at 12 V (ZXT13N15DE6), voltage headroom (ZXT13N50DE6), or drive efficiency (DMT3006LPSQ-13).

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum base current is 500 mA per the datasheet's Absolute Maximum Ratings table. However, for reliable continuous operation at 5 A collector current, the recommended base drive is 100 mA (IB = 100 mA at IC = 5 A), yielding hFE ≈ 50 and ensuring stable saturation without thermal runaway.
Can ZXT13N15DE6 be used in linear regulator applications?
No - this device is optimized for switching operation only. Its low VCE(sat) and high fT indicate design for saturated on/off states, not linear amplification. Linear use would exceed power dissipation limits (PD = 1.1 W) and risk thermal instability due to negative temperature coefficient of VBE.
How does the dual-emitter/dual-collector structure affect PCB layout?
The SOT26 pinout places E1/E2 and C1/C2 on opposite sides of the package, enabling symmetrical copper pours for balanced current sharing. Layout must tie E1–E2 and C1–C2 externally with minimum-length, equal-width traces to avoid current imbalance and localized heating at high duty cycles.
Is ZXT13N15DE6 compatible with lead-free reflow profiles?
Yes - it is fully RoHS-compliant and qualified for lead-free reflow per J-STD-020, with Moisture Sensitivity Level 1. The matte tin-plated leads withstand peak temperatures up to 260 °C for 10 seconds, matching standard Pb-free SAC305 process requirements without delamination or voiding.
