Product details
Overview
ZXTP25020DGTA from Diodes Incorporated is a 20V PNP medium-power high-gain transistor in SOT223 package, rated for -6A continuous collector current, with hFE > 200 at -1A and ultra-low RCE(sat) of 42 mΩ. It serves as a high-efficiency load switch or motor drive transistor in automotive-grade power control circuits compliant with AEC-Q101.
For engineers reviewing the ZXTP25020DGTA datasheet, ZXTP25020DGTA pinout, ZXTP25020DGTA application, or ZXTP25020DGTA equivalent, key selection criteria include guaranteed VCEO = -20V, BVCBO = -25V, low saturation voltage under high-current switching, thermal resistance RθJA = 41.7°C/W (on 50mm × 50mm 2oz copper), and AEC-Q101 qualification for automotive reliability.
Technical Context
This PNP bipolar junction transistor operates in linear and saturated switching modes, supporting high-current DC load control with minimal conduction loss. Its design emphasizes robust safe operating area (SOA) up to -20V/-6A, low VCE(sat) down to -150 mV at IC = -1A/IB = -10mA, and stable hFE across -55°C to +150°C junction temperature range.
The device features complementary NPN pairing with ZXTN25020DG, enabling push-pull or H-bridge configurations. Its SOT223 package provides enhanced thermal dissipation via exposed collector tab, validated by RθJL = 12.9°C/W junction-to-lead measurement and JEDEC-compliant ESD ratings (HBM 4 kV, MM 400 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -20 V - Maximum allowable collector-emitter voltage before breakdown in common-emitter configuration |
| IC (cont) | -6 A - Continuous collector current rating defining maximum steady-state load-handling capability |
| hFE @ -1A | >200 - Current gain ensuring low base drive requirement for efficient switching at 1A load |
| VCE(sat) @ -6A | -245 mV - Saturation voltage determining conduction loss and heat generation at full rated current |
| RCE(sat) | 42 mΩ - Equivalent on-resistance derived from VCE(sat)/IC, critical for power loss calculation |
| RθJA | 41.7 °C/W - Thermal resistance from junction to ambient on standard 50mm × 50mm 2oz PCB, defining heatsinking needs |
| ESD HBM | 4000 V - Human Body Model ESD rating confirming robustness during board assembly and handling |
Pinout & Package
Package: SOT223 - Surface-mount plastic package with exposed collector tab for thermal management; 0.112 g weight; UL 94V-0 flammability rating; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main current-carrying terminal (emitter of internal PNP structure) | Connected to high-side supply rail; thermally coupled to PCB copper for heat dissipation |
| Emitter (E) | Current source terminal (base-collector junction anode) | Typically tied to load return path; defines reference for VCE and VEBO ratings |
| Base (B) | Control input for minority-carrier injection | Receives negative bias current to turn on; requires IB ≥ -600 mA for full -6A saturation |
| Tab / Collector Pad | Exposed metal thermal pad | Electrically and thermally connected to collector; must be soldered to large copper pour for RθJA compliance |
Key Features
| Feature | Design Value |
|---|---|
| High current gain stability | hFE > 200 at -1A and > 20 at -6A ensures consistent drive efficiency across load range |
| Ultra-low saturation voltage | VCE(sat) ≤ -245 mV at -6A minimizes I²R losses and self-heating in high-duty-cycle operation |

Applications
| Automotive Engine Control | Industrial Motor Drive |
|---|---|
Use Scenario: Switching fuel injector solenoids in 12V engine management systems. IC Role / Device Role / Timing Role: High-side PNP switch controlling current flow to inductive loads with fast turn-off and flyback protection. Use Value: Low VCE(sat) reduces power loss during extended duty cycles; AEC-Q101 qualification ensures operation at -40°C to +125°C ambient. | Use Scenario: Driving brushed DC motors in factory automation actuators. IC Role / Device Role / Timing Role: Medium-power load switch enabling bidirectional control when paired with complementary NPN ZXTN25020DG. Use Value: 42 mΩ RCE(sat) limits conduction loss to <1.5 W at 6A, reducing heatsink requirements in space-constrained enclosures. |

IC Role / Device Role / Timing Role: Precision current sink regulating LED string current via base-controlled saturation. Use Value: Tight VCE(sat) tolerance (-150 mV to -255 mV) ensures ±3% current accuracy across production lots without trimming. |
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 |
|---|---|---|---|
| ZXTP2012GTA | VCEO = -20V, IC = -3A, hFE = 250@-1A, RCE(sat) = 75 mΩ | Lower current rating and higher saturation resistance limit use to sub-3A loads | Select when lower cost and reduced thermal demand outweigh need for 6A capacity |
| MJD2955T4G | VCEO = -60V, IC = -10A, hFE = 20–70@-4A, RCE(sat) = 150 mΩ | Higher voltage rating but significantly lower gain and higher conduction loss | Prefer for legacy designs requiring 60V breakdown margin where thermal budget allows higher VCE(sat) |
Compared with ZXTP25020DGTA, ZXTP2012GTA offers lower conduction loss per amp at light loads but cannot sustain 6A continuously, while MJD2955T4G trades gain and efficiency for rugged voltage headroom-making ZXTP25020DGTA optimal for compact, high-efficiency 20V automotive and industrial switches.

FAQ
What is the maximum safe operating temperature for ZXTP25020DGTA?
The device supports junction temperatures from -55°C to +150°C. For continuous operation at full -6A current, PCB layout must maintain RθJA ≤ 41.7°C/W using 50mm × 50mm 2oz copper; derating begins above +100°C ambient per the published thermal curve.
Can ZXTP25020DGTA replace a MOSFET in high-side switching applications?
Yes, but with trade-offs: it delivers lower gate-drive complexity than a P-channel MOSFET but requires sustained base current (≥ -600 mA at -6A) and exhibits higher conduction loss than low-RDS(on) MOSFETs. Best suited where bipolar simplicity, SOA robustness, and cost matter more than ultra-low static loss.
Is the SOT223 package lead-free and RoHS-compliant?
Yes - ZXTP25020DGTA carries matte tin-plated leads, conforms to EU RoHS Directive 2011/65/EU, and is halogen- and antimony-free ("Green") per Diodes Incorporated's specification: <900 ppm bromine/chlorine and <1000 ppm antimony compounds.
How does the complementary NPN ZXTN25020DG pair with this PNP transistor?
ZXTN25020DG matches ZXTP25020DG in voltage rating (VCEO = +20V), current capability (+6A), gain profile, and SOT223 packaging-enabling symmetrical push-pull, H-bridge, or complementary Darlington configurations without thermal or timing mismatch.
