Product details
Overview
ZXTN2011ZTA from Diodes Incorporated is a 100V NPN medium-power bipolar junction transistor in SOT89 package, rated for 4.5A continuous collector current and 10A peak pulse current, with VCE(sat) ≤ 60mV at IC = 1A and RCE(sat) = 31mΩ, designed for high-side switching and motor drive applications in industrial power interfaces.
For engineers reviewing the ZXTN2011ZTA datasheet, ZXTN2011ZTA pinout, ZXTN2011ZTA application, or ZXTN2011ZTA equivalent, key selection criteria include its AEC-Q101 qualification, low saturation voltage under high-current conditions (≤115mV at 2A), thermal resistance of 60°C/W on 50mm×50mm PCB, and validated performance up to +150°C junction temperature.
Technical Context
This NPN transistor operates as a medium-power switching device with high current gain retention-hFE ≥ 30 at IC = 5A and ≥10 at IC = 10A-enabling robust base drive efficiency in high-load scenarios. Its 100V VCEO rating and 200V VCBO support operation in 48V and 72V industrial bus systems with margin.
The SOT89 package provides low thermal resistance to ambient (60°C/W) and to lead (3.23°C/W), enabling direct mounting to copper pour without heatsink in moderate-duty cycles. Transient thermal impedance data confirms stable pulsed operation up to 10ms at full 10A peak current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - Supports switching in 48V/72V DC power rails with 2× safety margin against transients |
| IC (continuous) | 4.5 A - Enables sustained load control in motor drivers and SLIC circuits without forced cooling |
| VCE(sat) @ 1A | < 60 mV - Minimizes conduction loss (≤60 mW) and self-heating during steady-state operation |
| hFE @ 10A | ≥10 - Ensures reliable saturation with practical base drive (e.g., 1A IB) at full load |
| RθJA (50mm×50mm) | 60 °C/W - Allows 2.1W continuous dissipation at +70°C ambient without derating |
| ESD HBM | 4000 V - Meets IEC 61000-4-2 Level 4 for system-level ESD robustness in field-deployed equipment |
| TJ max | +150 °C - Qualified for under-hood automotive and high-temperature industrial environments |
Pinout & Package
Package: SOT89 - Surface-mount plastic package with exposed collector tab for thermal and electrical connection; 0.05g mass; UL 94V-0 rated; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (Tab) | Main current output path and thermal interface | Exposed metal tab electrically connected to collector; must be soldered to PCB copper pour for thermal management |
| Emitter | Current return node | Low-inductance emitter connection critical for fast turn-off and minimizing switching overshoot |
| Base | Control input | Requires current-limited drive (e.g., 100mA typical for 1A IC) to ensure saturation without overdrive loss |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per JESD22 |
| Low VCE(sat) at high current | 115 mV max at IC = 2A ensures <1W conduction loss in 24–48V motor control stages |
| High hFE retention to 10A | hFE ≥10 at full 10A pulse enables single-stage driver design without Darlington stacking |
| Green, halogen-free construction | <900 ppm Br/Cl, <1000 ppm Sb - Compliant with IPC-1752A Class 2 and EU ELV Directive |
| SOT89 thermal performance | RθJL = 3.23°C/W - Enables direct thermal coupling to PCB plane, reducing need for external heatsinks |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN2021ZTA | Same SOT89 package, but VCEO = 60V and IC = 3A; lower hFE at high current (≥5 @ 5A) | Restricted to ≤36V systems; unsuitable for 48V+ or high-voltage transient environments | Select only when lower voltage rating and reduced thermal demand justify cost savings |
| MJD122G | TO-252 package, VCEO = 100V, IC = 8A, but RθJA = 75°C/W (no copper pour); hFE drops to ≥20 @ 5A | Requires larger PCB area and heatsinking; less suitable for dense, thermally constrained layouts | Prefer when higher peak current (8A) is required and board space permits TO-252 mounting |
Compared with ZXTN2021ZTA and MJD122G, ZXTN2011ZTA uniquely balances 100V rating, 4.5A continuous current, and SOT89 thermal performance-making it optimal for space-limited 48V industrial switches where both voltage margin and thermal efficiency are critical.

FAQ
Is ZXTN2011ZTA pin-compatible with other SOT89 NPN transistors?
No-ZXTN2011ZTA uses a non-standard SOT89 pinout: Collector is the exposed tab (Pin 1), Emitter is Pin 2, Base is Pin 3. This differs from common SOT89 NPNs like MMBT4401 (Emitter-tab) and requires layout verification before substitution.
What is the maximum safe operating area (SOA) limit at 100°C case temperature?
At TC = 100°C, the SOA is limited to 1.2A at 50V or 0.6A at 100V for DC operation. Derating follows the 16.8 mW/°C linear factor above 25°C ambient, with pulse operation up to 10A permitted for ≤10ms at D ≤ 2% duty cycle.
Does ZXTN2011ZTA require a base resistor in all applications?
Yes-base current must be actively limited to prevent damage. For 1A collector current, a 100Ω resistor (with 5V drive) delivers ~45mA IB, satisfying the hFE-based requirement (IB ≥ IC/hFE ≈ 100mA at IC = 10A). Undriven base risks latch-up or thermal runaway.
Can ZXTN2011ZTA replace MOSFETs in high-side switch designs?
Yes-with caveats: it offers lower gate-drive complexity than N-channel MOSFETs but requires ~100mA base drive at 5A load versus MOSFET's µA gate leakage. Its 31mΩ RCE(sat) matches many 100V MOSFETs, though switching speed (ton/toff = 41/1010 ns) favors MOSFETs above 10kHz.
