Product details
Overview
ZXTP03200BZTA from Diodes Incorporated is a 200V PNP bipolar junction transistor in SOT-89 package, rated for −2 A continuous collector current and −5 A peak pulse current, with VCE(sat) ≤ −160 mV at −1 A and RCE(sat) = 130 mΩ, optimized for high-voltage DC-DC converter switching stages.
For engineers reviewing the ZXTP03200BZTA datasheet, ZXTP03200BZTA pinout, ZXTP03200BZTA application, or ZXTP03200BZTA equivalent, key selection criteria include its −200 V VCEO, low saturation voltage under high-current drive, thermal performance on 25 mm × 25 mm PCBs, and SOT-89 lead-frame thermal path to PCB copper.
Technical Context
This PNP transistor operates as a high-voltage, medium-power switch with robust avalanche-rated breakdown (V(BR)CEO = −220 V min), specified for pulsed operation up to 2% duty cycle. Its fT = 105 MHz supports fast turn-off in hard-switched topologies.
Thermal design relies on direct heat conduction from the collector tab to PCB copper: RθJL = 3.23 °C/W enables high transient power handling, while RθJA varies from 28 °C/W (2 oz copper, 25 mm² pad) to 117 °C/W (15 mm² pad), defining layout-dependent derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −200 V - Withstands 200 V reverse bias across collector-emitter in active switching without breakdown. |
| IC(cont) | −2 A - Supports continuous load current up to 2 A in linear or saturated switching modes. |
| VCE(sat) | −160 mV @ −1 A - Enables <0.16 W conduction loss per device at 1 A, critical for efficiency in high-current DC-DC stages. |
| fT | 105 MHz - Ensures adequate gain-bandwidth for sub-100 ns switching transitions in PWM controllers. |
| RθJL | 3.23 °C/W - Collector tab provides low-resistance thermal path to PCB, enabling >3× higher short-duration power than ambient-limited rating. |
| hFE | 50–300 - Wide DC current gain range supports both base-driven switching and analog amplification in feedback paths. |
| Cobo | 31 pF @ −10 V - Low output capacitance minimizes switching losses and improves EMI behavior in high-frequency converters. |
Pinout & Package
Package: SOT-89 - Surface-mount plastic package with exposed collector tab for thermal dissipation and mechanical anchoring; UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Emitter (E) | Current sink terminal | Connected to ground or low-side return path; must handle full load current and support fast charge extraction during turn-off. |
| Base (B) | Control input | Receives negative drive current to saturate; requires −400 mA base drive for full −2 A collector conduction. |
| Collector (C) | High-voltage output node | Exposed metal tab electrically connected to collector; serves as primary thermal interface to PCB copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| High breakdown voltage | V(BR)CEO = −220 V min ensures reliable operation in 150–200 V bus applications like industrial SMPS and LED drivers. |
| Low saturation resistance | RCE(sat) = 130 mΩ enables <0.26 W conduction loss at −2 A, reducing heatsink requirements in space-constrained designs. |
| Enhanced thermal path | Collector-tab RθJL = 3.23 °C/W allows >38 W short-pulse dissipation, supporting burst-mode or overload protection schemes. |
| Fast switching capability | td = 21 ns, tr = 18 ns, tf = 75 ns enable <200 ns total switching time, minimizing dead-time losses in synchronous converters. |
Applications
| Industrial DC-DC Converters | High-Voltage LED Drivers |
|---|---|
Use Scenario: Step-down conversion from 170–200 V DC bus to 12–48 V for factory automation I/O modules. IC Role / Device Role / Timing Role: Main high-side PNP switch in non-synchronous buck topology, driven by discrete gate controller. Use Value: −200 V VCEO eliminates need for series-connected transistors; low VCE(sat) maintains >92% efficiency at 2 A output. | Use Scenario: Constant-current regulation for high-brightness LED strings in street lighting systems operating from rectified AC line. IC Role / Device Role / Timing Role: Series-pass current switch modulated at 1–10 kHz to control LED brightness via PWM dimming. Use Value: 105 MHz fT ensures clean square-wave switching at dimming frequencies; RθJL = 3.23 °C/W sustains 2 A continuous current without forced air. |
| Telecom Power Supplies | Motor Drive Half-Bridge Legs |
Use Scenario: Isolated flyback auxiliary supply delivering 5 V/3 A for control circuitry in 48 V telecom rectifiers. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier driver stage, interfacing with optocoupler-isolated feedback loop. Use Value: hFE ≥ 50 at −2 A ensures stable base drive margin; −7 V VEBO prevents emitter-base junction breakdown during transient overvoltage events. | Use Scenario: High-side switch in 24–48 V brushed DC motor H-bridge for HVAC actuators and industrial valves. IC Role / Device Role / Timing Role: PNP-based high-side driver paired with NPN low-side switch, controlled by complementary logic-level signals. Use Value: −160 mV VCE(sat) at −1 A reduces conduction loss by 40% vs. standard PNP alternatives, extending battery runtime in portable units. |
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 = −120 V, IC = −2 A, VCE(sat) = −180 mV @ −1 A | Limited to ≤120 V bus systems; higher saturation voltage increases conduction loss by ~12% at 1 A. | Select only when system voltage is confirmed ≤100 V and thermal margin permits higher VCE(sat). |
| MJD2955T4G | VCEO = −70 V, IC = −10 A, TO-220 package, RθJA = 3 °C/W (with heatsink) | Lower voltage rating but higher current capacity; requires external heatsink and larger board area. | Prefer for ≤60 V applications needing >5 A peak current and active thermal management. |
Compared with ZXTP2012ZTA and MJD2955T4G, ZXTP03200BZTA uniquely balances −200 V rating, SOT-89 compactness, and sub-160 mV saturation in a single surface-mount device-enabling high-density, high-voltage DC-DC designs without compromising thermal or electrical margins.

FAQ
What is the maximum safe operating voltage for ZXTP03200BZTA in continuous DC applications?
The absolute maximum collector-emitter voltage is −200 V (VCEO). For reliable long-term operation, Diodes Incorporated recommends limiting steady-state VCE to ≤ −160 V to maintain safety margin against transients and temperature-induced drift. This aligns with typical derating practices for high-voltage BJTs in industrial power supplies.
Can ZXTP03200BZTA be used as a direct replacement for an NPN transistor in a circuit?
No-it is a PNP transistor and cannot substitute for an NPN without reversing biasing, polarity, and drive logic. Its emitter must be at higher potential than collector; base drive must be negative relative to emitter. Circuit redesign-including level-shifting and complementary drive topology-is required for functional equivalence.
How does the SOT-89 package affect thermal performance compared to TO-92 or TO-220?
The SOT-89's exposed collector tab provides significantly lower junction-to-lead thermal resistance (RθJL = 3.23 °C/W) than TO-92 (typically >200 °C/W), enabling higher power density. Unlike TO-220, it lacks a mounting hole but achieves comparable RθJA (28 °C/W) when soldered to 2 oz copper on 25 mm² pads-without requiring a heatsink.
Is ZXTP03200BZTA suitable for automotive applications per AEC-Q101?
No-ZXTP03200BZTA is not AEC-Q101 qualified. It is rated for −55 °C to +150 °C operating temperature but lacks automotive-specific stress testing, lot traceability, and failure rate validation. For automotive use, Diodes' AEC-Q101-qualified ZXTP2020ZTA or similar should be selected instead.
