Product details
Overview
ZXTP19100CFFTA from Diodes Incorporated is a 100V PNP medium-power transistor in SOT23F package, rated for -2A continuous collector current, -100V VCEO, and 1.5W power dissipation. It delivers low saturation voltage (VCE(SAT) = -120mV @ -1A) and 95mΩ on-resistance, making it suitable for high-efficiency DC-DC boost converters and gate driving of MOSFETs/IGBTs in industrial power management.
For engineers reviewing the ZXTP19100CFFTA datasheet, ZXTP19100CFFTA pinout, ZXTP19100CFFTA application, or ZXTP19100CFFTA equivalent, key selection criteria include verified VCEO ≥ -100V, hFE ≥ 200 at -100mA, RCE(SAT) ≤ 95mΩ, AEC-Q101 qualification, and SOT23F thermal performance with RθJA = 60°C/W on 50mm × 50mm 2oz Cu PCB.
Technical Context
This PNP bipolar junction transistor operates in linear and switching modes with characterized hFE up to -2A and guaranteed VCE(SAT) < -120mV at -1A/-100mA drive. Its breakdown ratings-VCBO = -110V, VEBO = -7V, and VECO = -7V-support robust blocking in bidirectional or reverse-polarity protection circuits.
The device uses a thermally enhanced SOT23F package with exposed collector pad, enabling 1.5W dissipation and RθJL = 43.8°C/W to lead. Transient thermal impedance data confirms stable pulsed operation up to 100ms, supporting motor and relay drive waveforms with peak IC = -3A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -100V - Ensures safe operation in 48V–72V bus systems with margin against transients. |
| IC (continuous) | -2A - Supports sustained load currents in lamp, relay, and siren drivers without derating. |
| VCE(SAT) | -120mV @ -1A/-100mA - Minimizes conduction loss and self-heating in high-duty-cycle switching. |
| hFE | 200–500 @ -100mA to -2A - Enables predictable base drive sizing across full current range. |
| RCE(SAT) | 95mΩ - Directly determines on-state power loss (P = I²R) in power switch applications. |
| PD | 1.5W (on 50mm × 50mm 2oz Cu) - Enables compact layout in space-constrained DC-DC modules. |
| ESD HBM | 4000V - Reduces handling sensitivity during automated assembly and field service. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTP2012ZTA | VCEO = -200V, IC = -1.5A, VCE(SAT) = -180mV @ -1A, SOT23 package (no exposed pad) | Higher voltage rating but lower current and worse thermal performance (RθJA = 200°C/W) | Select when >100V blocking is required and power density is secondary to voltage margin. |
| MMBT4403LT1G | VCEO = -40V, IC = -0.6A, VCE(SAT) = -0.75V @ -0.5A, SOT23 package | Lower voltage/current capability; unsuitable for 48V+ systems or >1A loads | Acceptable only in legacy 12V logic-level switching where thermal constraints are minimal. |
Compared with ZXTP19100CFFTA, ZXTP2012ZTA trades current capacity and thermal efficiency for higher voltage headroom, while MMBT4403LT1G lacks both the voltage rating and conduction performance needed for modern power management-making ZXTP19100CFFTA the optimal balance of 100V blocking, 2A drive, and 1.5W thermal capability in SOT23F.

FAQ
What is the maximum continuous collector current for ZXTP19100CFFTA?
The ZXTP19100CFFTA is rated for -2A continuous collector current at TA = +25°C with proper PCB copper area (50mm × 50mm, 2oz Cu). Derating applies above +25°C ambient per the 12.0 mW/°C linear factor specified in Note 7 of the datasheet, reaching zero power at +150°C junction temperature.
Is ZXTP19100CFFTA pin-compatible with standard SOT23 footprints?
Yes-the SOT23F package maintains the same 1.9mm × 2.9mm outline and 0.95mm lead pitch as industry-standard SOT23, allowing drop-in replacement on existing layouts. However, the exposed collector pad requires matching thermal pad design on the PCB to achieve rated 1.5W dissipation and 60°C/W RθJA.
How does the hFE performance vary across operating conditions?
hFE is characterized from -100mA to -2A: minimum 200 at -100mA/VCE = -2V, 135 at -1A, and 30 at -2A. This wide-range validation enables accurate base resistor calculation across full load conditions without extrapolation, supporting both linear regulation and saturated switching modes.
What thermal design guidance applies to ZXTP19100CFFTA's exposed collector pad?
The exposed collector pad must be soldered to a minimum 15mm × 15mm 1oz Cu area for basic operation (RθJA = 149°C/W), but achieving the full 1.5W rating requires connection to a 50mm × 50mm 2oz Cu plane. Thermal vias under the pad are recommended to enhance heat transfer to internal layers, especially in multilayer boards.
