Product details
Overview
ZXTP01500BGTC from Diodes Incorporated is a 500V PNP high-voltage transistor in SOT223 package, rated for -150mA continuous collector current and -500V VCEO, designed for high-voltage switching in offline power supplies, flyback controllers, and industrial snubber circuits.
For engineers reviewing the ZXTP01500BGTC datasheet, ZXTP01500BGTC pinout, ZXTP01500BGTC application, or ZXTP01500BGTC equivalent, key selection criteria include breakdown voltage margin, safe operating area under pulsed loads, thermal resistance with PCB copper area, and ESD robustness in high-noise environments.
Technical Context
This PNP bipolar junction transistor operates with a minimum BVCEO of -500V and supports peak pulse currents up to -500mA, enabling use in high-voltage transient suppression and energy recovery stages. Its hFE ranges from 15 to 300 across -1mA to -100mA collector currents, supporting both linear biasing and saturated switching.
The device features low VCE(SAT) of -500mV at -50mA/-10mA drive and fT of 60MHz, allowing fast turn-off (tOFF = 1.5µs) in high-frequency flyback topologies while maintaining stable gain under high-voltage stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -500V - Withstands full mains-referenced collector potentials in 230VAC offline designs without breakdown. |
| IC (cont.) | -150mA - Supports sustained current in auxiliary power rails and gate-drive isolation stages. |
| VCE(SAT) | -500mV @ -50mA/-10mA - Minimizes conduction loss in high-side switch configurations with low base drive overhead. |
| RθJA | 41.7°C/W (50mm×50mm 2oz Cu) - Enables 3W dissipation with ≤125°C junction rise above 25°C ambient in thermally optimized layouts. |
| fT | 60MHz - Supports clean switching transitions up to ~5–10MHz practical operating frequencies in resonant converters. |
| tOFF | 1.5µs - Ensures reliable blanking and timing control in PWM controllers with tight dead-time requirements. |
| ESD HBM | 4000V - Provides robust handling during PCB assembly and field-level surge events in industrial controls. |
Pinout & Package
Package: SOT223 - Surface-mount plastic package with exposed collector tab for thermal and electrical connection; 0.112g mass; UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (C) | Main high-voltage current path | Exposed metal tab - must be soldered to ≥25mm² copper pour for thermal management and voltage isolation compliance. |
| Emitter (E) | Current return node | Connected to high-side reference rail; requires creepage clearance ≥4.5mm per IEC 62368-1 at 500V working voltage. |
| Base (B) | Control input | Low-impedance drive required; -10mA base current needed for full saturation at -50mA collector load. |
Key Features
| Feature | Design Value |
|---|---|
| 500V breakdown rating | Enables direct replacement of older -400V PNP transistors in legacy 230VAC SMPS without redesigning snubber networks. |
| Green RoHS & halogen-free | Meets IPC-1752A Class 2 reporting requirements and automotive PPAP material declarations without CoC exceptions. |
| 14.8°C/W RθJL | Allows >80% of heat to transfer directly from junction to PCB via collector lead, reducing reliance on board-level thermal vias. |
| 1.5µs turn-off time | Permits use in 100kHz+ quasi-resonant flyback controllers where slow PNP devices previously limited efficiency. |
Applications
| Industrial Flyback Power Supply | High-Voltage Snubber Circuit |
|---|---|
Use Scenario: Primary-side switching in 12–24W offline AC/DC adapters for PLC I/O modules. IC Role / Device Role / Timing Role: High-side PNP switch controlling transformer primary current with zero-crossing synchronized gate drive. Use Value: -500V VCEO eliminates need for external clamping diodes, reducing BOM count by one high-voltage component. |
Use Scenario: Passive RCD snubber network across MOSFET drain in 400V DC bus inverters. IC Role / Device Role / Timing Role: Fast-recovery clamp transistor absorbing inductive kickback during IGBT turn-off. Use Value: 1.5µs tOFF ensures sub-microsecond clamping response, limiting dv/dt-induced shoot-through in half-bridge legs. |
| Capacitor Discharge Ignition (CDI) | Isolated Gate Drive Stage |
Use Scenario: Energy storage discharge switch in motorcycle and small-engine ignition systems. IC Role / Device Role / Timing Role: High-voltage PNP switch releasing stored capacitor charge into ignition coil primary winding. Use Value: -500mA ICM supports 10–15kV spark generation with single-pulse reliability over 10⁶ cycles. |
Use Scenario: Level-shifting stage driving high-side N-channel MOSFET in 3-phase motor gate drivers. IC Role / Device Role / Timing Role: Inverting level translator translating logic-level signals to ±15V referenced gate drive. Use Value: -900mV VBE(SAT) ensures minimal voltage drop across base-emitter path, preserving gate threshold margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage PNP switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTP01500BGT | Same die, tape-and-reel packaging differs (2,000 pcs vs. 4,000 pcs); identical electrical specs and thermal performance. | No functional difference; selected when smaller reel size aligns with SMT line changeover frequency. | Preferred for low-volume pilot builds or mixed-part feeders requiring shorter tape lengths. |
| MJD44H11T4G | -400V VCEO, -6A IC, TO-252 package; higher current but lower voltage rating and 3× larger footprint. | Suitable only where board space permits and system max voltage stays below 400V; not drop-in for 500V designs. | Consider only if thermal budget allows TO-252 mounting and design tolerates 100V lower breakdown margin. |
Compared with ZXTP01500BGT, the TC variant offers higher reel quantity for production continuity; versus MJD44H11T4G, it trades current headroom for critical 100V higher blocking capability in compact SOT223 form factor.

FAQ
What is the maximum allowable PCB copper area for thermal derating compliance?
The datasheet specifies two thermal test conditions: 25mm × 25mm and 50mm × 50mm 2oz copper. For full 3W power dissipation, the 50mm × 50mm layout is required. Smaller copper areas reduce allowable power linearly per the derating curve - e.g., 30mm × 30mm yields ~2.4W max at 25°C ambient.
Can ZXTP01500BGTC replace older PNPs like BD139 in high-voltage applications?
No - BD139 has only -80V VCEO and is unsuitable above 100V. ZXTP01500BGTC is intended to replace obsolete -400V to -500V PNP transistors such as MJE15033 or BU508A in new designs where SOT223 footprint and green compliance are required.
Does the SOT223 package require special soldering profile considerations?
Yes - the exposed collector tab acts as a thermal mass. Reflow profiles must ensure ≥220°C peak temperature for ≥60 seconds to achieve full wetting. Diodes Incorporated recommends using ENIG finish and avoiding OSP on the collector pad to prevent voiding and delamination.
Is ZXTP01500BGTC qualified for automotive applications?
No - the standard ZXTP01500BGTC is industrial-grade. The automotive-qualified version is ZXTP01500BGQ, which undergoes AEC-Q101 testing and ships with PPAP documentation. Mixing part numbers risks non-compliance in automotive programs.
