Product details
Overview
ZXTP19020DFF from Diodes Incorporated is a 20V PNP medium-power transistor in SOT23F package, rated for -5.5A continuous collector current and -15A peak pulse current, with VCE(SAT) < -44mV at -1A and RCE(SAT) = 26mΩ. It is AEC-Q101 qualified and used in MOSFET/IGBT gate driving circuits where low saturation voltage and high current gain at high IC are critical.
For engineers reviewing the ZXTP19020DFF datasheet, ZXTP19020DFF pinout, ZXTP19020DFF application, or ZXTP19020DFF equivalent, key selection criteria include guaranteed hFE ≥ 200 at -10A, thermal resistance as low as 60°C/W (50mm×50mm 2oz Cu), and complementary pairing with ZXTN19020DFF for push-pull switching stages.
Technical Context
This PNP bipolar junction transistor employs advanced process and SOT23F package design to maximize power density and thermal performance in space-constrained automotive and industrial switching applications. Its low RCE(SAT) and high-current gain stability support efficient gate drive of power semiconductors up to 20V rail voltages.
The device operates across -55°C to +150°C, features ESD ratings of 4kV HBM and 400V MM, and delivers fT = 176MHz at -50mA, enabling fast switching in motor control and DC-DC converter feedback paths where precise timing and minimal propagation delay are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -20V - Maximum safe collector-emitter blocking voltage with base open; defines upper limit for switch-off voltage in 12–20V systems. |
| IC (cont.) | -5.5A - Continuous current handling capability; supports sustained gate charging of large MOSFETs without derating at TA ≤ 70°C. |
| VCE(SAT) | < -44mV @ -1A - Low saturation voltage ensures minimal conduction loss and heat generation during active switching. |
| hFE | 200 min @ -10A - High, stable current gain at high collector current enables robust base drive with reduced IB overhead. |
| RθJA | 60°C/W - Thermal resistance with 50mm×50mm 2oz copper PCB; allows 1.5W dissipation up to +105°C ambient. |
| fT | 176MHz - Transition frequency confirms suitability for high-speed switching applications up to ~50MHz effective operation. |
| ESD HBM | 4,000V - Robust electrostatic discharge immunity reduces risk of field failure during automated assembly and handling. |

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 = -20V, IC = -3A, VCE(SAT) = -110mV @ -1A - lower current rating and higher saturation voltage. | Less suitable for >4A gate drive loads; acceptable only in low-power auxiliary switching. | Select when board space is identical but thermal budget allows higher VCE(SAT) loss. |
| MMDT3906-7-F | VCEO = -40V, IC = -200mA, hFE = 100 min @ -10mA - significantly lower current and power capability. | Only viable for signal-level logic inversion or biasing, not power switching. | Choose only for non-power functions where higher breakdown voltage is prioritized over current drive. |
Compared with ZXTP2012ZTA and MMDT3906-7-F, ZXTP19020DFF uniquely delivers -5.5A continuous current with < -44mV saturation voltage in SOT23F, making it the sole option among these three for high-current, low-loss gate driving in automotive and industrial power stages.

FAQ
What is the maximum allowable junction temperature for ZXTP19020DFF?
The absolute maximum operating junction temperature is +150°C, as specified in the Absolute Maximum Ratings table. Derating begins at +25°C ambient, with thermal resistance dropping to 60°C/W when mounted on 50mm×50mm 2oz copper, enabling full 1.5W dissipation up to +105°C ambient.
Is ZXTP19020DFF pin-compatible with any NPN complement?
Yes - ZXTN19020DFF is its designated complementary NPN counterpart, sharing identical SOT23F package, pinout (C-B-E), and thermal characteristics. Both devices are designed for matched push-pull operation in H-bridge and half-bridge gate driver stages.
Does ZXTP19020DFF require external base current limiting in typical gate drive applications?
Yes - base current must be actively limited to avoid exceeding the -1A absolute maximum rating. At -5.5A collector current, recommended base drive is -550mA (hFE ≥ 10), typically achieved using a series resistor or current-source driver stage.
Can ZXTP19020DFF be used in linear regulator applications?
No - it is optimized for switching operation, not linear regulation. Its low VCE(SAT) and high-current gain are intended for saturated switching, and its Safe Operating Area curve shows strong pulse-limited behavior rather than DC linear capability.
