Product details
Overview
PBHV9050Z-QX from Nexperia is a PNP high-voltage low-VCEsat transistor in SOT223 (SC-73) package, rated for −500 V VCEO, −250 mA IC, and −140 mV typical VCEsat at IC = −100 mA / IB = −20 mA. It delivers high hFE (80–300) at IC = −50 mA and is AEC-Q101 qualified for automotive motor management and flyback converters.
For engineers reviewing the PBHV9050Z-QX datasheet, PBHV9050Z-QX pinout, PBHV9050Z-QX application, or PBHV9050Z-QX equivalent, this device is selected for high-voltage switching where low saturation loss, thermal robustness on FR4 PCBs, and automotive-grade reliability are required - especially in LED chain drivers and telecom hook-switch circuits.
Technical Context
This PNP bipolar junction transistor operates with reverse-polarity high-voltage blocking (−500 V VCEO) and achieves low conduction loss via optimized epitaxial structure and emitter geometry. Its hFE remains stable across −55 °C to +150 °C ambient, supporting wide-temperature automotive operation.
Switching performance is characterized by 1.675 µs turn-on time and 1.75 µs turn-off time under standardized test conditions (VCC = −20 V, IC = −50 mA), with fT = 50 MHz enabling use in medium-frequency SMPS control stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −500 V - Enables direct use in 400 V DC bus flyback and telecom line interface without external voltage clamping. |
| IC | −250 mA continuous - Supports LED chain drivers up to 200 mA load with margin for pulse surges. |
| VCEsat | −140 mV typ. @ IC/IB = 5 - Reduces conduction loss to <35 mW at 200 mA, improving thermal efficiency on standard FR4. |
| hFE | 80–300 @ IC = −50 mA - Ensures reliable base drive design with low base current overhead in discrete gate driver stages. |
| Rth(j-sp) | 20 K/W - Low junction-to-solder-point thermal resistance enables 1.4 W power dissipation with 6 cm² collector pad on FR4. |
| fT | 50 MHz - Supports switching frequencies up to ~5 MHz in optimized Class-E or quasi-resonant topologies. |
| toff | 1750 ns - Allows clean commutation in 100–500 kHz SMPS with minimal tail current and shoot-through risk. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with 4 leads, 2.3 mm pitch, and integrated heatsink pad (lead 2 and 4 both connected to collector). Dimensions: 6.5 mm × 3.5 mm × 1.65 mm body; mounting pad for collector recommended at 6 cm² for full 1400 mW rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input requiring negative bias relative to emitter; designed for low-impedance drive to ensure fast saturation. |
| 2 | Collector (C) | Main high-voltage current path; electrically tied to lead 4 and thermal pad - must be routed to large copper area for thermal management. |
| 3 | Emitter (E) | Reference node for output stage; connects to system ground or return rail in high-side switch configurations. |
| 4 | Collector (C) | Duplicate collector terminal for enhanced current handling and thermal conduction; soldered directly to PCB heatsink plane. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under temperature cycling, HTRB, and ESD stress - supports under-hood motor control modules. |
| Low VCEsat at high IC | −140 mV typ. @ −100 mA ensures <15 mW conduction loss per transistor in parallel LED string drivers. |
| High VCEO with tight distribution | Guaranteed −500 V minimum allows single-device replacement of stacked BJT solutions in 380–450 V AC/DC front-ends. |
| Stable hFE over temperature | hFE ≥ 70 @ −100 mA and Tj = 100 °C - simplifies base resistor selection across full industrial temperature range. |
| Optimized for FR4 thermal performance | Rth(j-a) = 90 K/W with 6 cm² collector pad - eliminates need for metal-core PCB in cost-sensitive automotive lighting designs. |
Applications
| Electronic Ballasts | LED Chain Driver |
|---|---|
Use Scenario: High-frequency resonant ballast for T5/T8 fluorescent lamps operating from 220–240 V AC mains. IC Role / Device Role / Timing Role: Main high-voltage PNP switch in half-bridge output stage, driven by dedicated gate transformer. Use Value: −500 V VCEO withstands reflected flyback spikes; low VCEsat reduces heat sink size by 30% vs. legacy MJD series. |
Use Scenario: Constant-current driver for 12–24 LED strings in commercial signage with dimming via PWM base control. IC Role / Device Role / Timing Role: Linear or switched-series pass element regulating current through LED chain with analog/PWM base bias. Use Value: Stable hFE across temperature prevents current drift >±3% over −40 to +85 °C ambient. |
| LCD Backlighting | Automotive Motor Management |
Use Scenario: CCFL or edge-lit LED backlight in automotive instrument clusters requiring EMI-robust discrete switching. IC Role / Device Role / Timing Role: High-side PNP switch controlling boost converter enable or inverter gate drive sequencing. Use Value: Fast toff (1750 ns) enables precise timing alignment with microcontroller PWM outputs for flicker-free dimming. |
Use Scenario: Window lift, seat adjust, or HVAC blower motor driver in 12 V systems with reverse-battery and load-dump protection. IC Role / Device Role / Timing Role: High-side switch in discrete H-bridge or half-H configuration, controlled by MCU GPIO with level-shifting. Use Value: AEC-Q101 qualification and −55 to +150 °C operation ensure compliance with ISO 16750-2 mechanical/environmental requirements. |
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 |
|---|---|---|---|
| PHPT60303SQ | −60 V VCEO, −3 A IC, SOT223 - lower voltage, higher current, MOSFET-based. | Not suitable for 400 V bus applications; limited to 24–48 V automotive subsystems. | Select only when system voltage ≤60 V and RDS(on)-driven efficiency outweighs BJT's linear gain advantages. |
| MJD44H11T4G | −80 V VCEO, −8 A IC, TO-220 - higher current but insufficient voltage rating for flyback primary side. | Requires external snubber or stacking for >100 V operation; not AEC-Q101 qualified. | Use only in non-automotive industrial SMPS where voltage derating and qualification are not mandated. |
Compared with PHPT60303SQ and MJD44H11T4G, PBHV9050Z-QX uniquely combines automotive qualification, −500 V blocking, and low-VCEsat in SOT223 - making it the only drop-in solution for space-constrained 400 V LED drivers and telecom hook switches.

FAQ
What is the maximum safe operating junction temperature for PBHV9050Z-QX?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of hFE and VCEsat. Derating is required above 25 °C ambient: total power dissipation drops linearly to zero at 125 °C ambient when mounted on FR4 with 6 cm² collector pad.
Can PBHV9050Z-QX replace older MJD series transistors in existing designs?
Yes - PBHV9050Z-QX shares the SOT223 footprint and pinout (B-C-E-C) with MJD44H11 and MJD2955, but offers −500 V VCEO vs. −80 V or −100 V. Direct replacement is viable only if voltage stress in the circuit stays within −500 V; otherwise, layout review for creepage and clearance is mandatory.
Is the collector pad (pins 2 and 4) internally connected to the die substrate?
Yes - pins 2 and 4 are electrically and thermally bonded to the collector region of the silicon die. The exposed copper pad beneath the package must be soldered to a dedicated PCB copper pour serving as both electrical connection and heatsink; floating or unconnected pads cause thermal runaway and premature failure.
Does PBHV9050Z-QX support pulsed operation beyond its DC ratings?
Yes - peak collector current (ICM) is rated at −500 mA for single pulses ≤1 ms, and base current (IBM) up to −200 mA. Pulse operation must respect SOA limits: at VCE = −400 V, maximum pulse width is 10 µs for IC = −250 mA to avoid secondary breakdown.
