Product details
Overview
ZXTN19100CGTA from Diodes Incorporated is a 100V NPN medium-power low-saturation transistor in SOT223 package, rated for 5.5A continuous collector current and 10A peak pulse current, with VCE(sat) < 65 mV at 1 A and on-resistance RSAT = 43 mΩ at 6 A. It serves as a high-reliability high-side switch in motor drive and SLIC applications.
For engineers reviewing the ZXTN19100CGTA datasheet, ZXTN19100CGTA pinout, ZXTN19100CGTA application, or ZXTN19100CGTA equivalent, key selection criteria include its AEC-Q101 qualification, 100V BVCEO, low saturation voltage under high-current switching, and thermal resistance of 42 °C/W (52 mm × 52 mm 2 oz copper).
Technical Context
This NPN bipolar junction transistor features a rugged silicon die optimized for medium-power linear and switching operation, with specified hFE up to 5.5 A ensuring stable gain retention under load. Its 200 V BVCBO and 100 V BVCEO support robust line-switching in industrial power rails.
The device delivers fast switching performance (tON = 51.9 ns, tOFF = 1095 ns) and exhibits low output capacitance (COBO = 15.7–25 pF), enabling efficient operation in DC fan drivers and subscriber line interface circuits where voltage transients and thermal cycling are common.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - supports operation across 48 V and 72 V industrial bus systems without breakdown risk |
| IC (cont.) | 5.5 A - enables direct driving of small DC motors or solenoids without external current amplification |
| VCE(sat) | < 65 mV @ 1 A - minimizes conduction loss and self-heating in high-duty-cycle switching |
| RSAT | 43 mΩ @ 6 A - provides predictable on-state resistance for accurate power loss modeling |
| hFE | 25–500 - wide gain range ensures reliable base drive design across temperature and current extremes |
| fT | 150 MHz - sufficient for PWM frequencies up to ~10 MHz with margin for layout parasitics |
| RθJA | 42 °C/W - requires ≥52 mm × 52 mm 2 oz copper pad for full 3.0 W dissipation at ambient |
Pinout & Package
Package: SOT223 - surface-mount plastic package with exposed collector tab for enhanced thermal conduction; 0.112 g mass; UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Emitter connection | Low-impedance return path; tied to ground or low-side reference in high-side switch configurations |
| Pin 2 (Base) | Control input | Receives current-limited drive signal; requires ≥550 mA base current for full 5.5 A saturation |
| Pin 3 (Collector) | Power output | Exposed metal tab - must be soldered to large copper area for thermal management and electrical connection |
| Pin 4 (Collector Tab) | Collector connection | Primary current-carrying and heat-dissipating terminal; electrically identical to Pin 3 |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HBM ESD (4 kV), and mechanical shock |
| Low VCE(sat) at high IC | 65 mV @ 1 A enables <100 mW conduction loss per switch in 12–48 V systems |
| High-current hFE specification | hFE = 190 @ 5.5 A ensures predictable base drive sizing without derating assumptions |
| Green, halogen-free construction | Meets RoHS 2 and JEDEC J-STD-020 Level 1 moisture sensitivity for standard reflow compatibility |
Applications
| Motor Driving (DC Fans) | High-Side Switches |
|---|---|
Use Scenario: Controlling 24 V/1 A brushless DC cooling fans in industrial PLC enclosures with ambient temperatures up to +85 °C. IC Role / Device Role / Timing Role: NPN power switch operating in saturated on/off mode, driven by microcontroller GPIO via base resistor network.

IC Role / Device Role / Timing Role: Linear-mode current source and switching element in hybrid SLIC front-end stages. Use Value: Stable hFE up to 5.5 A enables precise loop current regulation; low COBO (15.7 pF) preserves signal integrity in 20 kHz ringing waveforms. |
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 |
|---|---|---|---|
| ZXTN2010ZTA | Lower VCEO (80 V), higher VCE(sat) (120 mV @ 1 A), same SOT223 package | Not suitable for 100 V line-switching; acceptable only in ≤48 V motor drives with relaxed efficiency targets | Select only if cost is primary constraint and 80 V rating suffices |
| MJD122G | Higher VCEO (100 V), lower IC (3 A), TO-252 package with higher RθJA (60 °C/W) | Requires larger PCB area and additional thermal vias; unsuitable for space-constrained SOT223 layouts | Choose when legacy TO-252 footprint compatibility is mandatory |
Compared with ZXTN2010ZTA and MJD122G, ZXTN19100CGTA uniquely balances 100 V rating, 5.5 A current capability, ultra-low saturation voltage, and SOT223 thermal performance-making it optimal for compact, high-efficiency industrial switching where both voltage headroom and conduction loss matter.

FAQ
What is the maximum allowable junction temperature for ZXTN19100CGTA?
The absolute maximum operating junction temperature is +150 °C, with storage temperature ranging from –55 °C to +150 °C. Derating begins at +25 °C ambient, and full 3.0 W power dissipation requires a 52 mm × 52 mm 2 oz copper pad per the datasheet's thermal test condition.
Is ZXTN19100CGTA suitable for linear (analog) operation?
Yes-it is characterized for linear use with specified hFE up to 5.5 A and VBE(on) = 0.95–1.05 V at 5.5 A. However, safe operating area (SOA) limits must be observed: at 100 V VCE, maximum continuous current drops to ~100 mA due to second breakdown constraints.
Does ZXTN19100CGTA require a heatsink in typical SOT223 mounting?
No dedicated heatsink is required if mounted per recommended layout: soldered to ≥52 mm × 52 mm 2 oz copper with thermal vias. On smaller pads (e.g., 25 mm × 25 mm 1 oz), RθJA rises to 78 °C/W, limiting continuous power to ~1.6 W at +25 °C ambient.
How does the SOT223 pinout differ from standard transistor packages?
ZXTN19100CGTA uses a 4-terminal SOT223: Pins 1 (E), 2 (B), 3 (C), and an exposed collector tab (Pin 4). Unlike TO-92 or SOT-23, the collector tab is electrically and thermally integral to Pin 3-both must be connected to the same net and thermal plane for proper operation and reliability.
