Product details
Overview
ZXTP19100CZQTA from Diodes Incorporated is a 100V PNP medium-power transistor in SOT89 package, rated for -2A continuous collector current and -100mV VCE(SAT) at -1A, with AEC-Q101 qualification for automotive applications. It delivers low on-resistance (100mΩ), high breakdown voltage (BVCEO = -100V), and robust thermal performance (RθJA = 28°C/W on 50mm × 50mm 2oz Cu), used in automotive LED drivers and DC-DC converter output stages.
For engineers reviewing the ZXTP19100CZQTA datasheet, ZXTP19100CZQTA pinout, ZXTP19100CZQTA application, or ZXTP19100CZQTA equivalent, key selection criteria include verified VCE(SAT) at -2A, AEC-Q101 compliance status, SOT89 thermal pad mounting requirements, and complementary NPN pairing with ZXTN19100CZ.
Technical Context
This PNP bipolar junction transistor operates in linear and switching modes with guaranteed BVCEO ≥ -100V and BVECO ≥ -7V, supporting reverse-blocking configurations in high-side switch topologies. Its fT = 142MHz enables stable operation up to mid-frequency switching applications.
The device features a thermally enhanced SOT89 package with exposed collector pad, delivering RθJL = 4.7°C/W to lead and enabling 4.46W power dissipation under optimized PCB layout (50mm × 50mm 2oz Cu). ESD ratings meet JEDEC Class 3A HBM (4kV) and MM (400V).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTP2012ZQTA | VCEO = -100V, IC = -1.5A, VCE(SAT) = -180mV @ -1A, same SOT89 package | Lower current rating and higher saturation voltage reduce efficiency in 2A loads | Select when lower cost and reduced thermal demand justify 0.5A derating |
| MJD122T4G | VCEO = -100V, IC = -2A, but TO-252 package, RθJA = 60°C/W (no thermal pad) | Larger footprint and inferior thermal performance require larger heatsinking | Choose only if SOT89 assembly is incompatible and board space allows TO-252 |
Compared with ZXTP2012ZQTA and MJD122T4G, ZXTP19100CZQTA uniquely combines -2A rating, -130mV VCE(SAT), and SOT89 thermal pad for highest power density in automotive space-constrained designs.

FAQ
What is the maximum continuous collector current for ZXTP19100CZQTA?
The ZXTP19100CZQTA is rated for -2A continuous collector current at TA = +25°C with appropriate PCB copper area (50mm × 50mm 2oz Cu). Derating applies above +25°C ambient, reaching zero at +150°C junction temperature per the absolute maximum ratings table.
Does ZXTP19100CZQTA have an exposed thermal pad, and how must it be connected?
Yes, the SOT89 package features an exposed collector pad (Pin 3) that must be soldered directly to a minimum 15mm² copper area on the PCB. This pad serves as both the collector terminal and primary thermal path; failure to connect it results in RθJA degrading from 28°C/W to 117°C/W.
Is ZXTP19100CZQTA pin-compatible with its complementary NPN counterpart?
Yes, ZXTN19100CZ uses the identical SOT89 package with matching pinout (Emitter/Base/Collector), enabling direct layout reuse in complementary push-pull or H-bridge designs. Both share identical mechanical dimensions, thermal characteristics, and AEC-Q101 qualification.
What is the base-emitter turn-on voltage specification for ZXTP19100CZQTA?
VBE(ON) is specified as -840mV (typical) to -950mV (max) at IC = -2A and VCE = -2V. This value determines required base drive voltage headroom and influences base resistor sizing in saturated-switch applications.
