Product details
Overview
ZXT13N20DE6TA from Diodes Incorporated is a 20V NPN low-saturation switching transistor in SOT26 package, rated for 4.5A continuous collector current and 15A peak pulse current, with RCE(SAT) = 38 mΩ and VCE(sat) ≤ 75 mV at 1A - optimized for high-efficiency DC–DC converters and power switches in automotive-grade (AEC-Q101) applications.
For engineers reviewing the ZXT13N20DE6TA datasheet, ZXT13N20DE6TA pinout, ZXT13N20DE6TA application, or ZXT13N20DE6TA equivalent, key selection criteria include verified 20V VCEO, low 38 mΩ on-resistance, AEC-Q101 qualification, thermal resistance of 73 °C/W (RθJA), and SOT26 lead-free packaging compliant with RoHS and halogen-free "Green" standards.
Technical Context
This NPN bipolar junction transistor is engineered for fast-switching, low-loss power control in compact DC–DC topologies. Its hFE is characterized up to 15A (min 15 @ IC = 15A), supporting robust base drive design across wide load ranges.
The device features a safe operating area (SOA) validated for pulsed operation up to 100 ms, with transient thermal impedance enabling reliable performance under repetitive short-duration loads. ESD ratings meet JEDEC HBM Class 3A (4 kV) and MM (400 V), ensuring robustness in automated assembly and field environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 20 V - Maximum sustainable collector-emitter voltage before breakdown; defines upper rail limit in 12–19V automotive and industrial power stages. |
| IC (continuous) | 4.5 A - Continuous current-handling capability at TA = 25°C; supports mid-power switching without forced cooling. |
| RCE(SAT) | 38 mΩ - Equivalent on-resistance at high current; enables <100 mW conduction loss at 1.5A, critical for thermal budget in sealed enclosures. |
| VCE(sat) @ 1A | ≤ 75 mV - Confirmed saturation voltage ensures minimal voltage drop and heat generation during active switching in synchronous rectifier or load switch roles. |
| fT | 96 MHz - Current gain-bandwidth product; supports clean turn-on/turn-off transitions up to ~10 MHz switching frequencies in PWM-controlled regulators. |
| RθJA | 73 °C/W - Junction-to-ambient thermal resistance under short-duration conditions; enables >1W dissipation with modest PCB copper area (25 mm × 25 mm, 1 oz). |
| ESD HBM | 4 kV - Human Body Model rating per JESD22-A114; qualifies for handling in standard electronics manufacturing without special ESD controls. |
Pinout & Package
Package: SOT26 - surface-mount, 6-pin plastic package with exposed collector tab for enhanced thermal conduction; dimensions per AP02002 (3.00 × 2.80 × 1.10 mm); moisture sensitivity level 1 (J-STD-020); matte tin-plated leads, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Emitter terminal | Reference node for base drive; connects to ground or low-side return path in common-emitter configurations. |
| Pin 2 (Base) | Control input | Receives current-limited drive signal; requires ≥45 mA for full saturation at 4.5A IC. |
| Pin 3 (Collector) | Power output | Main current-carrying terminal; electrically and thermally connected to exposed pad for PCB heat sinking. |
| Pin 4 (Emitter) | Emitter terminal (redundant) | Dual-emitter configuration improves current sharing and reduces bond wire inductance in high-di/dt switching. |
| Pin 5 (Base) | Control input (redundant) | Second base connection lowers drive impedance and enhances switching consistency across temperature. |
| Pin 6 (Collector) | Power output (redundant) | Second collector terminal reinforces thermal and electrical connection to PCB copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| Low saturation voltage | VCE(sat) ≤ 75 mV @ 1A enables sub-100 mW conduction loss, reducing thermal stress in space-constrained power modules. |
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS power supplies requiring extended temperature (-55°C to +150°C) reliability. |
| High peak pulse current | ICM = 15A supports surge-tolerant operation during motor startup, capacitor charging, or fault transients without secondary protection. |
| Halogen- and antimony-free "Green" construction | Meets <900 ppm Br, <900 ppm Cl, <1000 ppm Sb limits - satisfies strict environmental compliance for EU, China RoHS, and OEM sustainability programs. |
| Thermal resistance optimization | RθJL = 18.6 °C/W (junction-to-lead) allows direct heat transfer to PCB copper, enabling >1.5W steady-state dissipation with minimal heatsinking. |

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 |
|---|---|---|---|
| ZXT13N50DE6TA | Higher VCEO = 50V, same SOT26 package and RCE(SAT) ≈ 38 mΩ, but lower hFE at high current (min 10 @ 15A). | Better suited for 48V industrial systems; less optimal for automotive 12V/24V due to higher capacitance and reduced gain linearity below 10V. | Select when system rail exceeds 25V and SOA margin above 20V is required; verify base drive sufficiency at 15A. |
| DMT3006LPSQ-13 | MOSFET (30V, 6.2 mΩ, SOT26), zero gate charge, but lacks AEC-Q101 qualification and exhibits higher gate drive complexity. | Enables ultra-low-loss operation in battery-powered devices; unsuitable for automotive due to missing qualification and lower ESD robustness (HBM 2 kV). | Prefer for consumer/portable designs where gate drive simplicity and <10 mΩ RDS(on) outweigh qualification needs. |
Compared with ZXT13N50DE6TA and DMT3006LPSQ-13, ZXT13N20DE6TA delivers optimal balance of AEC-Q101 compliance, 20V SOA headroom, and proven bipolar drive simplicity - making it the preferred choice for cost-sensitive, thermally constrained automotive and industrial switching where 12–24V rails dominate.

FAQ
Is ZXT13N20DE6TA pin-compatible with standard SOT23-3 transistors?
No. ZXT13N20DE6TA uses the SOT26 package - a 6-pin variant with dual emitter, dual base, and dual collector terminals. It is not pin-compatible with 3-pin SOT23-3 devices. PCB layout must follow AP02002 footprint, including dedicated thermal pad connections for pins 3 and 6 (collectors) and pins 1 and 4 (emitters).
What base drive current is required to achieve full saturation at 4.5A collector current?
To achieve VCE(sat) ≤ 230 mV at IC = 4.5A, the datasheet specifies IB = 45 mA (IC/IB = 100). This requires a base resistor ≤ 100 Ω when driven from a 5V logic source with 0.85V VBE(on), and sufficient current sourcing capability from the controller GPIO or driver stage.
Does ZXT13N20DE6TA support operation above 100°C junction temperature?
Yes. The device is rated for TJ = –55°C to +150°C and qualified to AEC-Q101. At 150°C, hFE drops to min 15 at IC = 15A, and VCE(sat) increases by ~2.5× versus 25°C. Derating is required: maximum continuous IC falls to ~2.8A at TA = 100°C with RθJA = 73 °C/W and no additional heatsinking.
Can ZXT13N20DE6TA be used in linear regulator applications?
No. While it operates in active region, its Safe Operating Area (SOA) is optimized for switching - not linear regulation. At VCE = 10V and IC = 100mA, power dissipation reaches 1W, exceeding the 1.1W PD limit at TA = 25°C unless actively cooled. Linear use risks thermal runaway and second breakdown outside pulsed SOA boundaries.
