Product details
Overview
ZXTP19100CGTA from Diodes Incorporated is a 100V PNP medium-power bipolar junction transistor in SOT223 package, rated for -2A continuous collector current, with VCE(sat) < -130mV at -1A and RCE(sat) = 100mΩ. It features high breakdown voltage (BVCEO > -100V), AEC-Q101 qualification, and is optimized for high-side switching in motor drive circuits.
For engineers reviewing the ZXTP19100CGTA datasheet, ZXTP19100CGTA pinout, ZXTP19100CGTA application, or ZXTP19100CGTA equivalent, this device serves as a robust, RoHS-compliant, halogen-free PNP switch with validated thermal performance on 50mm × 50mm 2oz copper PCBs and documented safe operating area limits up to -100V/–2A.
Technical Context
This PNP transistor operates in linear and saturation modes with DC current gain (hFE) of 200–500 at IC = -100mA and drops to 20–28 at IC = -2A, indicating strong low-current amplification but intentional design for switching rather than analog amplification. Its fT = 142MHz confirms usable high-frequency switching capability despite power-class packaging.
The device's safe operating area (SOA) is defined for single-pulse and DC conditions, with VCEX = -110V and thermal resistance RθJA as low as 23.5°C/W under optimal 50mm × 50mm 2oz copper layout-enabling stable operation in thermally demanding industrial motor control nodes without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -100V - supports high-side switching in 48V and 72V industrial bus systems with margin |
| IC (continuous) | -2A - delivers sufficient current for small-to-medium brushed DC motors and solenoid drivers |
| VCE(sat) | -130mV @ -1A - minimizes conduction loss and self-heating during active switching |
| RCE(sat) | 100mΩ - enables accurate current-sense resistor placement in emitter-follower configurations |
| hFE | 20–500 - wide gain range allows flexible base drive design across load currents |
| fT | 142MHz - supports PWM frequencies up to ~10MHz with controlled rise/fall times (tr = 22.4ns, tf = 107ns) |
| RθJA | 23.5°C/W (50mm×50mm 2oz Cu) - permits 1.6W dissipation at ≤85°C ambient without heatsink |
Pinout & Package
Package: SOT223 - surface-mount, thermally enhanced plastic case with exposed collector tab; 0.112g mass; UL 94V-0 flammability rating; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | E | Current source terminal; connects to load return path; requires low-impedance ground routing |
| Pin 2 (Base) | B | Control input; driven with negative current to turn on; requires series resistor for IB limiting |
| Pin 3 (Collector) | C | High-side power node; electrically and thermally connected to exposed metal tab; must be soldered to large copper pour |
| Pin 4 (Collector Tab) | C (thermal) | Primary heat path to PCB; not electrically isolated; must be tied to system ground or supply rail per layout |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM 4kV) |
| Low VCE(sat) | –130mV at –1A enables <130mW conduction loss per switch, reducing thermal stress |
| High BVCEO | –100V rating supports operation in 48V battery systems with transient margin against load dump |
| Green construction | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); RoHS 2 compliant with lead-free matte tin plating |
| Thermally optimized | RθJL = 16°C/W to lead enables direct thermal coupling to PCB copper, improving power handling by 2.5× vs standard SOT-23 |
Applications
| Motor Drive | High-Side Load Switch |
|---|---|
Use Scenario: Driving brushed DC motors in automotive HVAC actuators and industrial valve positioners. IC Role / Device Role / Timing Role: PNP high-side switch controlling 24–48V motor supply rails with PWM duty cycle modulation. Use Value: Low VCE(sat) reduces I²R losses during 100% duty cycle stall conditions; AEC-Q101 ensures field longevity. | Use Scenario: Enabling/disabling power to sensor modules or communication interfaces in programmable logic controllers. IC Role / Device Role / Timing Role: High-side power switch providing controlled inrush current and reverse-polarity protection. Use Value: 100mΩ RCE(sat) limits voltage drop to <200mV at 2A, preserving downstream rail regulation accuracy. |
| Industrial Solenoid Control | Power Supply OR-ing |
Use Scenario: Actuating 24V/48V solenoids in factory automation safety interlocks and pneumatic control valves. IC Role / Device Role / Timing Role: Fast-turning PNP switch delivering peak current pulses up to –3A (ICM) for solenoid pull-in. Use Value: 660ns storage time (ts) and 107ns fall time (tf) enable precise pulse-width control for force modulation. | Use Scenario: OR-ing redundant 12V/24V power supplies in telecom shelf management units. IC Role / Device Role / Timing Role: Reverse-polarity protected high-side diode replacement using PNP configuration. Use Value: VBE(on) = –950mV at –2A provides predictable forward voltage drop lower than Schottky alternatives at high current. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-side switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTP2012GTA | VCEO = -200V, IC = -1.5A, VCE(sat) = -200mV @ -1A, SOT223 | Higher voltage rating but higher saturation voltage; lower current capability | Select when >100V transients are expected and 2A continuous current is not required |
| ZXTN19100CGTA | Complementary NPN type; VCEO = +100V, IC = +2A, same package and thermal specs | Used in low-side switching or push-pull topologies requiring matched PNP/NPN pairs | Select when designing complementary driver stages or NPN-based load switching where high-side PNP is not needed |
Compared with ZXTP2012GTA, ZXTP19100CGTA offers 30% lower VCE(sat) at 1A and 0.5A higher continuous current, making it preferable for efficiency-critical motor drives; versus ZXTN19100CGTA, it enables high-side topology without level-shifting circuitry but requires inverted control logic.

FAQ
What is the maximum allowable junction temperature for ZXTP19100CGTA?
The absolute maximum junction temperature is +150°C, with continuous operation recommended up to +125°C. Derating begins at +25°C ambient, and thermal resistance RθJA drops to 23.5°C/W only when mounted on 50mm × 50mm 2oz copper-smaller pads increase thermal impedance significantly.
Can ZXTP19100CGTA be used in parallel for higher current?
No-this PNP transistor lacks inherent current-sharing characteristics due to negative temperature coefficient of VBE(sat); paralleling risks thermal runaway. For >2A loads, use a single higher-rated device like DMTH10H025LPS or implement active current balancing.
Is the SOT223 collector tab electrically isolated?
No-the collector tab is electrically connected to Pin 3 (collector) and must be routed to the same net. It is not insulated; PCB land pattern must avoid accidental shorting to adjacent traces or planes unless intentionally tied to system ground or supply rail.
What base drive current is required to fully saturate ZXTP19100CGTA at –2A collector current?
Full saturation at –2A requires IB = –200mA (IC/IB = 10), per datasheet test condition yielding VCE(sat) = –220mV. For reliable switching, design base drive to deliver ≥–250mA peak with fast edge rates to minimize storage time ts = 660ns.
