Product details
Overview
ZXTP25015DFH from Diodes Incorporated (formerly Zetex Semiconductors) is a PNP medium-power bipolar junction transistor in SOT23 package, rated for -15V VCEO, -4A IC(cont), 1.25W PD on 50mm×50mm PCB, and -55mV VCE(sat) @ -1A/-100mA, used in high-side driver and MOSFET/IGBT gate drive circuits.
For engineers reviewing the ZXTP25015DFH datasheet, ZXTP25015DFH pinout, ZXTP25015DFH application, or ZXTP25015DFH equivalent, key selection criteria include verified saturation voltage at high current, thermal derating behavior on defined PCB copper area, reverse blocking capability (VECO = -3V), and complementary pairing with ZXTN25015DFH.
Technical Context
This PNP transistor employs an advanced epitaxial process to achieve low VCE(sat) (-55mV typ. @ -1A/-100mA) and high DC current gain (hFE = 300–900 at -10mA). Its -15V forward blocking (VCEO) and -3V reverse blocking (VECO) ratings support bidirectional switching roles in gate drive and load switch topologies.
Thermal performance is explicitly characterized across four PCB mounting conditions: RJA ranges from 171°C/W (15mm×15mm, 1oz Cu) to 69°C/W (50mm×50mm, 2oz Cu), enabling precise junction temperature estimation under real layout constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -15 V - Maximum collector-emitter voltage before breakdown in normal forward-active operation |
| IC(cont) | -4 A - Continuous collector current rating with 1.25W dissipation on 50mm×50mm/2oz Cu PCB |
| VCE(sat) | -55 mV @ -1A/-100mA - Confirmed low saturation voltage enabling <0.055W conduction loss at 1A |
| VECO | -3 V - Reverse emitter-collector blocking capability, critical for high-side switch flyback handling |
| hFE | 90–900 - DC current gain range spanning -4A to -10mA operating points, supporting wide base drive flexibility |
| fT | 295 MHz - Transition frequency confirming suitability for fast-switching gate drive up to ~100MHz edge rates |
| RJA | 69 °C/W - Minimum junction-to-ambient thermal resistance achievable with optimized 50mm×50mm copper pour |
Pinout & Package
SOT23-3 (TO-236AB) package: compact 2.80–3.04 mm × 2.10–2.64 mm footprint, 1.12 mm max height, 3-lead surface-mount outline with gull-wing leads. Standard JEDEC MO-203AA compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current source terminal in PNP configuration; connects to positive rail in high-side switch |
| 2 (Base) | B | Control input requiring negative current injection to saturate; compatible with standard logic-level drivers |
| 3 (Collector) | C | Output node tied to load; reverse-biased during off-state to block -15V forward and -3V reverse voltage |
Key Features
| Feature | Design Value |
|---|---|
| High power dissipation in SOT23 | 1.25W on 50mm×50mm/2oz Cu - Enables discrete PNP switching without TO-220 or DPAK in space-constrained designs |
| Low VCE(sat) | -55mV @ -1A/-100mA - Reduces conduction loss by >40% vs. typical SOT23 PNP transistors (> -100mV) |
| Complementary pairing | Matched with ZXTN25015DFH NPN - Supports push-pull, H-bridge, and totem-pole output stages with balanced VCE(sat) and hFE |
| High peak current capability | -10A ICM - Supports short-duration surge loads in motor commutation and inductive load switching |

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 |
|---|---|---|---|
| ZXTP2012Z | VCEO = -20V, VCE(sat) = -120mV @ -1A/-100mA, PD = 1.0W | Higher voltage rating but higher saturation loss; lower power dissipation limit | Select when >-15V blocking is required and thermal margin allows higher VCE(sat) penalty |
| MMBT4403 | VCEO = -40V, VCE(sat) = -750mV @ -500mA/-50mA, PD = 350mW | Higher voltage rating but significantly higher saturation voltage and lower current/power capability | Select only for low-current (<500mA), high-voltage signal switching where thermal budget is not constrained |
Compared with ZXTP25015DFH, ZXTP2012Z trades lower VCE(sat) for higher VCEO and reduced thermal capacity, while MMBT4403 offers wider voltage margin at the cost of 13× higher conduction loss and 3.6× lower power handling-making ZXTP25015DFH optimal for high-efficiency, medium-current, space-limited gate drive.

FAQ
What is the maximum continuous collector current for ZXTP25015DFH under standard PCB conditions?
The maximum continuous collector current is -4A, validated at 1.25W power dissipation on a 50mm×50mm×1.6mm FR4 PCB with high-coverage single-sided 2oz copper. Derating begins at 9.6mW/°C above 25°C ambient, requiring thermal design verification for sustained operation above 85°C junction temperature.
Can ZXTP25015DFH be used as a direct replacement for ZXTN25015DFH in complementary circuits?
No-ZXTP25015DFH is a PNP device, while ZXTN25015DFH is its complementary NPN counterpart. They are designed to operate together in push-pull or totem-pole configurations, not as substitutes. Swapping them would invert circuit functionality and likely cause failure due to polarity mismatch in biasing and current flow.
What is the significance of the -3V VECO rating in practical circuit design?
The -3V emitter-collector reverse breakdown rating defines the maximum reverse voltage the device can block when the emitter is biased positive relative to the collector-critical in high-side switch configurations where inductive kickback or bus transients may reverse-bias the E-C junction. Exceeding this rating risks avalanche conduction and potential device failure.
How does the SOT23 package achieve 1.25W power dissipation despite its small size?
The 1.25W rating is achieved only with aggressive PCB thermal design: a 50mm×50mm copper pour with 2oz thickness and high coverage reduces RJA to 69°C/W. On smaller or thinner copper areas, power rating drops to 1.05W (25mm×25mm/2oz) or 0.73W (15mm×15mm/1oz), requiring layout-aware derating in actual designs.
