Product details
Overview
ZXTN19100CFFTA from Diodes Incorporated is a 100V NPN medium-power low-saturation transistor in SOT23F package, delivering 4.5A continuous collector current, VCE(SAT) < 60mV @ 1A, RCE(SAT) = 38mΩ, and AEC-Q101 qualification-designed for high-side switching in motor drives and SLIC applications.
For engineers reviewing the ZXTN19100CFFTA datasheet, ZXTN19100CFFTA pinout, ZXTN19100CFFTA application, or ZXTN19100CFFTA equivalent, key selection criteria include breakdown voltage (BVCEO = 100V), thermal resistance (RθJA = 60°C/W on 50mm×50mm 2oz Cu), safe operating area at 100μs–DC, and complementary PNP pairing with ZXTP19100CFF.
Technical Context
This NPN bipolar junction transistor uses an advanced process to achieve high-voltage blocking (BVCEX = 200V) while maintaining low saturation resistance. Its base-emitter breakdown (BVECO = 5V) and emitter-collector reverse blocking capability support robust operation in bidirectional line-switching topologies.
The device operates across –55°C to +150°C with ESD ratings of 4kV HBM and 400V MM. Thermal performance is defined under three PCB mounting conditions: RθJA = 149°C/W (15mm×15mm 1oz Cu), 93°C/W (25mm×25mm 2oz Cu), and 60°C/W (50mm×50mm 2oz Cu).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100V - Enables use in 48V and 72V industrial bus switching without derating. |
| IC (continuous) | 4.5A - Supports sustained load currents in DC fan and small-motor drivers. |
| VCE(SAT) @ 1A/100mA | <60mV - Minimizes conduction loss and self-heating in high-duty-cycle switches. |
| RCE(SAT) | 38mΩ - Directly determines I²R power dissipation at full rated current. |
| PD (max, 50mm×50mm) | 2.0W - Achievable only with optimized copper pour; derates linearly above +25°C ambient. |
| fT | 150MHz - Sufficient for PWM frequencies up to ~10MHz with stable gain margin. |
| hFE @ 5A | 25–500 - Wide gain spread requires external base-current limiting for consistent saturation. |
Pinout & Package
SOT23F is a low-profile, surface-mount plastic package with exposed collector pad for enhanced thermal transfer. It maintains pin compatibility with standard SOT23 but delivers higher power density via improved thermal resistance (RθJL = 43.8°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitting terminal for majority carriers | Low-impedance return path; must be routed with minimal inductance in high-dI/dt switching. |
| 2 (Base) | Control electrode for carrier injection | Requires current-limited drive (IB ≤ 1A) to avoid second-breakdown during turn-on. |
| 3 (Collector) | Current collection node with exposed pad | Exposed metal pad connects directly to PCB ground/power plane for thermal and electrical integrity. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress. |
| Low VCE(SAT) at high current | 45mV typical @ 1A/100mA enables <100mW conduction loss in 48V high-side switch designs. |
| High BVCEX = 200V | Supports flyback energy recovery and transient clamping in inductive load switching. |
| Complementary PNP pair | ZXTP19100CFF shares identical SOT23F footprint and voltage/current specs for H-bridge layout symmetry. |
| Green, halogen-free construction | Meets J-STD-020 Level 1 moisture sensitivity and RoHS 2 / EU Directive 2011/65/EU requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN high-voltage switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN2010F | VCEO = 100V, IC = 3A, VCE(SAT) = 85mV @ 1A, SOT23F | Lower current rating and higher saturation voltage reduce efficiency in 4A+ loads. | Select when lower cost is prioritized over thermal margin and peak current headroom. |
| MJD122G | VCEO = 100V, IC = 5A, TO-220 package, RθJA = 65°C/W (with heatsink) | Larger footprint and leaded package incompatible with dense SMT layouts; superior heat spreading. | Choose for high-reliability industrial systems where manual assembly and heatsinking are acceptable. |
Compared with ZXTN2010F and MJD122G, ZXTN19100CFFTA uniquely balances 4.5A current, ultra-low 38mΩ RCE(SAT), and SOT23F compactness-making it optimal for thermally constrained, high-density motor and line-switching designs requiring AEC-Q101 compliance.

FAQ
What is the maximum safe operating voltage for ZXTN19100CFFTA in continuous forward-blocking mode?
The maximum continuous collector-emitter voltage is VCEO = 100V, verified per JEDEC JESD78 testing. In forward-blocking configuration with base open, operation beyond this rating risks avalanche-induced secondary breakdown. For transient tolerance, BVCEX = 200V applies only under pulsed conditions with RBE < 1kΩ or VBE between –1V and +0.25V.
Can ZXTN19100CFFTA be used in parallel configurations to increase current handling?
No-ZXTN19100CFFTA lacks built-in current-sharing features such as matched hFE or integrated emitter resistors. Its hFE variation (25–500 at 5A) causes severe current imbalance. Parallel operation requires external emitter ballast resistors and individual base drive, which negates the thermal and layout advantages of the SOT23F package.
Is the SOT23F package's exposed collector pad required to be soldered to a thermal pad on the PCB?
Yes-the exposed collector pad is electrically and thermally part of the collector terminal. Per datasheet Note 9, RθJL = 43.8°C/W assumes the pad is fully soldered to ≥15mm² of 1oz copper. Omitting this connection degrades RθJA by up to 90°C/W and risks thermal runaway at >1.5A continuous current.
Does ZXTN19100CFFTA support reverse-biased operation as an emitter-follower?
It supports limited reverse operation: BVECO = 5V and VECO = 5V define emitter-collector breakdown with base open. However, hFE in reverse mode is not characterized, and safe operating area curves apply only to forward-active and saturation regions. Use in reverse-emitter configurations requires external clamping and is not recommended for production designs.
