Product details
Overview
ZXTP4003ZTA from Diodes Incorporated is a 100V PNP bipolar junction transistor optimized for LED TV backlight driving, featuring BVCEO = −100 V, continuous collector current IC = −1 A, DC current gain hFE ≥ 100 at IC = −150 mA / VCE = −0.2 V, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the ZXTP4003ZTA datasheet, ZXTP4003ZTA pinout, ZXTP4003ZTA application, or ZXTP4003ZTA equivalent, key selection factors include its high-voltage PNP switching capability, SOT89 thermal performance (RθJL = 17.46 °C/W), and verified suitability in constant-current LED string control circuits with fast turn-off timing (ts = 1348 ns @ VCC = −80 V).
Technical Context
This PNP transistor operates as a high-side switch in LED current-source configurations, leveraging its −100 V VCEO rating to withstand transient voltage spikes in backlight boost converters. Its hFE range (60–133) supports stable linear-mode biasing across temperature (−55°C to +150°C) and enables predictable base drive design.
Thermal management relies on the exposed collector pad in the SOT89 package, delivering RθJL = 17.46 °C/W to PCB copper-critical for sustained −1 A operation. Switching behavior is characterized under pulsed conditions (300 µs, ≤2% duty cycle), with tr = 388 ns and tf = 382 ns confirming suitability for medium-frequency PWM dimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −100 V: Withstands peak reverse voltage in LED string high-side switching without breakdown. |
| IC (continuous) | −1 A: Supports full-brightness operation of multi-LED strings in 4K/8K TV backlights. |
| hFE | ≥100 @ −150 mA / −0.2 V: Ensures low base drive current requirement for efficient microcontroller interfacing. |
| RθJL | 17.46 °C/W: Enables direct thermal path from junction to PCB copper, reducing heatsink dependency. |
| ts (storage) | 1348 ns @ −80 V: Defines minimum off-time in PWM dimming; impacts maximum achievable dimming frequency. |
| PD | 1.5 W @ 25°C on 25 mm × 25 mm FR4: Sets practical power limit for surface-mount thermal design. |
Pinout & Package
Package: SOT89 - thermally enhanced plastic case with exposed collector pad, UL 94V-0 rated, moisture sensitivity level 1, matte tin-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | E | Current source node; connects to LED anode or supply rail in high-side configuration. |
| Pin 2 (Base) | B | Control input; requires negative base-emitter bias (VBE(on) = −0.71 to −0.95 V) to saturate. |
| Pin 3 (Collector) | C | Power output node; electrically and thermally tied to exposed metal tab for PCB heat sinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-voltage switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTP2012ZTA | VCEO = −200 V, IC = −0.5 A, hFE = 100–200 @ −100 mA | Higher voltage margin but lower current capacity; suited for ultra-high-voltage LED supplies (>150 V). | Select when system transients exceed −100 V but average current demand is ≤500 mA. |
| MJD44H11T4G | VCEO = −80 V, IC = −8 A, TO-220 package, RθJA = 2.5 °C/W | Higher current and thermal dissipation, but larger footprint and no AEC-Q101 qualification. | Choose for industrial non-automotive designs needing >1 A and active heatsinking. |
Compared with ZXTP4003ZTA, ZXTP2012ZTA trades current capability for voltage headroom, while MJD44H11T4G offers higher power handling in a through-hole package-neither matches the combination of AEC-Q101, SOT89 thermal efficiency, and −1 A/−100 V balance.

FAQ
What is the maximum safe operating temperature for ZXTP4003ZTA?
The device is rated for junction temperatures from −55°C to +150°C. Under continuous −1 A operation on a 25 mm × 25 mm FR4 board with 1 oz copper, ambient must remain ≤85°C to maintain TJ ≤150°C, given RθJA = 83 °C/W and PD = 1.5 W.
Can ZXTP4003ZTA be used in linear (analog) dimming mode?
Yes-its hFE stability across temperature (60–133) and low VBE(on) variation (−0.71 to −0.95 V) support precise analog current regulation. However, power dissipation must be limited to ≤1.5 W, requiring careful thermal design at high VCE.
Is the SOT89 package lead-free and RoHS compliant?
Yes-ZXTP4003ZTA uses matte tin-plated terminals and halogen/antimony-free "Green" molding compound, meeting RoHS Directive 2011/65/EU and Diodes Incorporated's environmental policy without purposefully added lead.
Does ZXTP4003ZTA require a base resistor in PWM switching applications?
Yes-a series base resistor is required to limit IB to ≤−500 mA (absolute max) and ensure saturation at target IC. For −150 mA collector current and hFE ≥ 100, a 1.5 kΩ resistor with −5 V drive yields ~−3.3 mA base current, providing adequate overdrive.
