Product details
Overview
PBHV9050Z from Nexperia is a PNP high-voltage bipolar junction transistor (BJT) designed for switching in high-voltage DC-DC and AC-DC power stages. It delivers 500 V collector-emitter peak voltage (VCESM), 250 mA continuous collector current (IC), and ultra-low 140–350 mV VCEsat at IC = −100 mA / IB = −20 mA, enabling efficient operation in LED chain drivers and flyback converters.
For engineers reviewing the PBHV9050Z datasheet, PBHV9050Z pinout, PBHV9050Z application, or PBHV9050Z equivalent, key selection criteria include verified high-voltage blocking capability, low saturation voltage under pulsed high-current conditions, thermal resistance to solder point (Rth(j-sp) = 20 K/W), and SOT223 package suitability for medium-power surface-mount thermal management.
Technical Context
This PNP BJT operates with open-base VCEO = −500 V and peak VCESM = −500 V, supporting robust isolation in telecom hook-switch and SMPS primary-side switch applications. Its hFE ranges from 70 to 300 (at IC = −10 mA to −100 mA, VCE = −10 V, pulsed), ensuring reliable base drive efficiency across load conditions.
Switching performance is characterized by ton = 1675 ns and toff = 1750 ns under standardized test conditions (VCC = −20 V, IC = −0.05 A, IBon = −5 mA, IBoff = 10 mA), with fT = 50 MHz confirming usable gain-bandwidth for moderate-speed switching control loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCESM | −500 V: Enables safe operation in 400 V DC bus and 380 VAC rectified systems without derating. |
| VCEsat (typ) | −140 mV at IC = −100 mA / IB = −20 mA: Reduces conduction loss and self-heating in sustained on-state operation. |
| hFE (min) | 70 at IC = −100 mA: Ensures sufficient current gain to minimize base drive power in discrete driver circuits. |
| Rth(j-sp) | 20 K/W: Supports direct thermal coupling to PCB copper pour, enabling 1.4 W dissipation with <1°C/W board-level thermal path. |
| fT | 50 MHz: Validates usable small-signal gain up to switching frequencies typical of 100–500 kHz flyback and LED driver topologies. |
| Cc | 6 pF at VCB = −20 V: Limits Miller capacitance impact on gate/base drive dynamics in high-dV/dt environments. |
Pinout & Package
The PBHV9050Z is housed in an SC-73 (SOT223) plastic surface-mount package with integrated heatsink pad (pin 4), measuring 6.5 mm × 3.5 mm × 1.65 mm and featuring a 2.3 mm lead pitch. The collector is internally connected to pins 2 and 4 for enhanced thermal and current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal accepting negative base current to turn on the PNP device; requires current-limiting resistor in series with driving source. |
| 2 | Collector (C) | Main high-voltage current sink node; electrically and thermally tied to pin 4 for dual-path conduction and heat spreading. |
| 3 | Emitter (E) | High-side reference node connected to positive rail; carries full load current and defines output polarity in common-emitter configuration. |
| 4 | Collector (C) | Dedicated thermal and electrical extension of collector; must be soldered to ≥6 cm² copper pad for rated 1400 mW power dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage blocking | −500 V VCESM rating enables direct use in 380 VAC-derived supplies without series stacking or snubbers. |
| Low VCEsat | −140 mV typical saturation voltage reduces conduction losses by >40% vs. standard PNP transistors at 100 mA load. |
| Medium-power SMD package | SOT223 with dual-collector terminals supports 1.4 W dissipation on FR4 with 6 cm² copper, eliminating need for through-hole alternatives. |
| High hFE at high IC | hFE ≥ 70 at −100 mA ensures stable switching with minimal base drive current, easing design of discrete gate drivers. |
Applications
| Electronic Ballasts | LED Chain Drivers |
|---|---|
|
Use Scenario: High-frequency resonant ballast for T5/T8 fluorescent lamps operating from 220–240 VAC mains. IC Role / Device Role: PNP switch controlling lamp current in half-bridge inverter primary side. Use Value: −500 V rating withstands reflected flyback spikes; low VCEsat minimizes thermal stress during 25–50 kHz switching. |
Use Scenario: Constant-current driver for 10–20 LED series strings in commercial signage. IC Role / Device Role: Series-pass switch regulating current in buck-derived topology with isolated feedback. Use Value: Stable hFE across temperature ensures consistent current regulation; SOT223 thermal pad maintains <90 °C junction rise at 200 mA. |
| LCD Backlighting | Flyback Converters |
|
Use Scenario: CCFL or edge-lit LED backlight in industrial panel displays powered from 12–24 VDC input. IC Role / Device Role: Primary-side switch in self-oscillating or PWM-controlled flyback stage generating 300–600 V bias. Use Value: Fast switching (ton/toff < 1.7 µs) supports >100 kHz operation; low Cc limits capacitive coupling noise into feedback circuitry. |
Use Scenario: 5–15 W offline flyback converter for industrial sensor power supplies. IC Role / Device Role: Main switching transistor in discontinuous conduction mode (DCM) primary circuit. Use Value: −500 V VCEO eliminates need for external clamping diodes; Rth(j-sp) = 20 K/W allows full 250 mA rating without heatsink. |
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 |
|---|---|---|---|
| PHPT60303XK | Lower VCEO (−300 V); higher VCEsat (−250 mV typ); same SOT223 package. | Restricted to ≤265 VAC-derived inputs; less suitable for telecom hook-switch or 400 V bus designs. | Select only when system peak voltage remains ≤300 V and thermal margin permits higher saturation loss. |
| BCP56-16 | Lower VCEO (−100 V); higher hFE (100–250); TO-261AA (SOT-223 variant) with single collector pin. | Not viable for >120 V applications; lacks dual-collector thermal path for >700 mW dissipation. | Use only in low-voltage (<100 V) linear or switching regulators where cost sensitivity outweighs voltage/thermal requirements. |
Compared with PHPT60303XK and BCP56-16, PBHV9050Z uniquely combines 500 V blocking, sub-200 mV VCEsat, and dual-collector SOT223 thermal design-making it the only option among the three qualified for 400 V DC bus flyback and telecom hook-switch duty cycles without derating.

FAQ
What is the maximum continuous collector current for PBHV9050Z?
The PBHV9050Z supports a maximum continuous collector current (IC) of −0.25 A at Tamb ≤ 25 °C with proper PCB thermal management (6 cm² collector pad). At elevated ambient temperatures, current must be derated per the power derating curve in Figure 1-e.g., to ~180 mA at Tamb = 75 °C.
Can PBHV9050Z replace a MOSFET in high-voltage switching applications?
No-it is a bipolar PNP transistor requiring sustained base current for conduction, unlike voltage-driven MOSFETs. While it offers lower VCEsat than many PNP alternatives, its base drive demand and slower switching versus modern HV MOSFETs make it unsuitable as a direct MOSFET replacement without circuit redesign.
Is PBHV9050Z automotive-qualified?
No. Per Nexperia's revision history (v.3, October 2024), PBHV9050Z is explicitly designated as non-automotive qualified. It has not undergone AEC-Q101 stress testing or automotive-specific qualification-use in automotive systems requires verified alternatives such as the PBHV9050Z-Q series.
How does the dual-collector pin (pins 2 and 4) affect PCB layout?
Pins 2 and 4 are internally shorted to the same collector node and must both be soldered to a shared thermal pad. The pad should be ≥6 cm² of 1 oz copper on the component layer, connected via multiple thermal vias to inner-layer ground or power planes to achieve the rated 1400 mW dissipation and 20 K/W Rth(j-sp).
