Product details
Overview
ZXT10N20DE6TA from Diodes Incorporated is a 20V NPN low-saturation switching transistor in SOT26 package, rated for 3.5A continuous collector current and 19A peak pulse current, with RCE(SAT) = 55 mΩ and VCE(SAT) ≤ 90 mV at 1 A - optimized for high-efficiency DC–DC converters and motor control switches.
For engineers reviewing the ZXT10N20DE6TA datasheet, ZXT10N20DE6TA pinout, ZXT10N20DE6TA application, or ZXT10N20DE6TA equivalent, key selection criteria include verified AEC-Q101 qualification, low on-resistance under high-current drive (IC/IB = 50), thermal resistance of 73 °C/W (RθJA, short pulse), and ESD robustness (4 kV HBM).
Technical Context
This NPN bipolar junction transistor operates as a saturated switch in power management circuits, featuring fully characterized hFE up to 6 A and guaranteed BVCEO ≥ 20 V. Its low VCE(SAT) (90 mV max @ 1 A) and tight RCE(SAT) tolerance (55 mΩ typ.) enable minimal conduction loss in high-duty-cycle switching.
The device uses a thermally enhanced SOT26 package with exposed collector lead, delivering RθJL = 18.6 °C/W and supporting linear derating to 13.6 mW/°C above 25 °C. It meets AEC-Q101 stress testing for automotive-grade reliability and exhibits 4 kV HBM ESD immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 20 V - Ensures safe operation in 12 V automotive and industrial bus systems with margin against transients. |
| IC (cont.) | 3.5 A - Supports sustained load switching in compact DC–DC converter output stages without forced cooling. |
| RCE(SAT) | 55 mΩ - Delivers <190 mV VCE(SAT) at 3.5 A, minimizing I²R losses and thermal rise in high-current paths. |
| fT | 140 MHz - Enables fast switching (>1 MHz PWM) with controlled turn-on (170 ns) and turn-off (400 ns) times. |
| RθJA | 73 °C/W (t ≤ 5 s) - Allows >1.7 W pulsed power dissipation on standard FR4 PCBs with minimal copper area. |
| ESD HBM | 4,000 V - Reduces risk of assembly-line damage and improves field reliability in unshielded power modules. |
Pinout & Package
Package: SOT26 - surface-mount, 6-pin plastic package with exposed collector tab for thermal enhancement; moisture sensitivity level 1 per J-STD-020; weight ≈ 0.015 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (C) | Collector | Primary high-current output node; electrically and thermally connected to exposed metal pad for heatsinking. |
| 2 (E) | Emiter | Current return path; tied to ground or low-side reference in common-emitter switching configurations. |
| 3 (B) | Base | Control input; requires ~100 mA drive at 3.5 A IC to maintain saturation with IC/IB = 35. |
| 4 (C) | Collector (redundant) | Second collector connection - paralleled internally with Pin 1 to reduce lead inductance and improve thermal spreading. |
| 5 (E) | Emiter (redundant) | Second emitter connection - reduces bond wire resistance and enhances current sharing in high-pulse applications. |
| 6 (B) | Base (redundant) | Second base connection - lowers drive impedance and improves switching consistency under high-frequency PWM. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power electronics including engine control modules and body electronics. |
| Low VCE(SAT) (90 mV @ 1 A) | Reduces conduction loss by >40% vs. standard BJT alternatives, enabling higher efficiency in 5–12 V buck converters. |
| hFE characterized to 6 A | Enables predictable base drive design across full operating range - no gain roll-off uncertainty at rated current. |
| SOT26 dual-collector/dual-emitter layout | Improves current handling and thermal distribution versus 3-pin SOT23, supporting 19 A peak pulses without bond-wire failure. |
| Halogen- and antimony-free "Green" construction | Meets IPC-1752A material declaration requirements and supports RoHS-compliant manufacturing flow. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXT13N50DE6TA | Higher VCEO = 50 V, lower hFE (100–200 @ 6 A), RCE(SAT) = 120 mΩ | Better suited for 48 V industrial supplies; less efficient at 12 V due to higher saturation voltage | Select when system bus voltage exceeds 25 V and thermal budget allows higher VCE(SAT) |
| MJD122-TP | TO-252 package, VCEO = 100 V, IC = 8 A, RCE(SAT) = 150 mΩ, no AEC-Q101 qualification | Requires larger PCB footprint and lacks automotive qualification; higher power handling but lower efficiency | Choose only for non-automotive 100 V applications where SOT26 size constraint does not apply |
Compared with ZXT10N20DE6TA, ZXT13N50DE6TA trades off efficiency for higher voltage capability, while MJD122-TP sacrifices miniaturization and qualification for raw current capacity - making ZXT10N20DE6TA optimal for space-constrained, AEC-Q101–required 12–20 V switching.

FAQ
What is the maximum continuous collector current for ZXT10N20DE6TA?
The ZXT10N20DE6TA is rated for 3.5 A continuous collector current at TA = +25 °C with proper PCB thermal relief. Derating applies above 25 °C: 13.6 mW/°C for t ≤ 5 s, and 8.8 mW/°C for steady-state operation on a 25 mm × 25 mm 1 oz copper pad.
Is ZXT10N20DE6TA suitable for automotive applications?
Yes - ZXT10N20DE6TA is explicitly qualified to AEC-Q101 standards and marked "AEC-Q101" in its ordering information. It undergoes stress testing for temperature cycling, humidity, and mechanical shock required for under-hood and body electronics use.
How many collector terminals does the SOT26 package have?
The SOT26 package has two dedicated collector terminals (Pins 1 and 4), both electrically and thermally connected to the same internal die region and exposed metal pad - this dual-collector configuration reduces effective lead resistance and improves thermal spreading.
What is the typical VCE(SAT) at 3.5 A collector current?
At IC = 3.5 A and IB = 100 mA (IC/IB = 35), the typical VCE(SAT) is 190 mV, with a maximum of 250 mV per the datasheet's electrical characteristics table - measured under pulsed conditions (≤300 µs, ≤2% duty cycle).
