Product details
Overview
PBHV9040Z/ZLX from Nexperia is a PNP high-voltage bipolar junction transistor (BJT) designed for switching in high-voltage DC circuits, featuring −500 V collector-emitter peak voltage (VCESM), −0.25 A continuous collector current (IC), and ultra-low −110 mV typical collector-emitter saturation voltage (VCEsat) at IC = −100 mA / IB = −20 mA. It serves as a robust high-side switch in LED driver modules, automotive HID front lighting, and electronic ballasts.
For engineers reviewing the PBHV9040Z/ZLX datasheet, PBHV9040Z/ZLX pinout, PBHV9040Z/ZLX application, or PBHV9040Z/ZLX equivalent, key selection criteria include its AEC-Q101 qualification, SOT223 thermal performance (Rth(j-sp) = 20 K/W), low VCEsat under high-voltage bias, and verified operation up to 150 °C junction temperature.
Technical Context
This PNP BJT operates with open-base collector-emitter voltage rating of −400 V (VCEO) and supports pulsed peak collector current up to −0.5 A (ICM). Its DC current gain (hFE) ranges from 10 to 200 depending on operating point - 100–200 at −50 mA/−10 V, dropping to 10–25 at −250 mA due to high-current saturation effects.
Switching performance is characterized by 1819 ns typical turn-on time (ton) and 1800 ns turn-off time (toff) under −0.15 A load, with transition frequency fT = 55 MHz at −10 mA/−10 V. Thermal resistance to solder point is 20 K/W when mounted on FR4 with 6 cm² collector pad, enabling stable power dissipation up to 1.4 W at Tamb ≤ 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCESM | −500 V peak collector-emitter voltage: enables reliable blocking in 400 V DC bus applications like LED chains and HID lamps. |
| VCEsat (typ) | −110 mV at IC = −100 mA / IB = −20 mA: reduces conduction loss and heat generation in high-duty-cycle switching. |
| hFE (min) | 100 at IC = −50 mA / VCE = −10 V: ensures sufficient base drive margin for stable saturation in automotive motor management. |
| Ptot | 1.4 W at Tamb ≤ 25 °C with 6 cm² copper pad: supports medium-power switching without active cooling in space-constrained SMD layouts. |
| Rth(j-sp) | 20 K/W junction-to-solder-point: allows direct thermal coupling to PCB ground plane for predictable thermal design in LED drivers. |
| AEC-Q101 | Qualified per Automotive Electronics Council standard: validated for use in automotive lighting and motor control systems. |
| fT | 55 MHz at IC = −10 mA / VCE = −10 V: supports fast switching in SMPS and telecom hook-switch applications up to ~10 MHz. |
Pinout & Package
The PBHV9040Z/ZLX is housed in an SC-73 (SOT223) plastic surface-mount package with four leads, where pins 2 and 4 are internally connected to the collector for enhanced thermal and current handling. The package measures 6.5 mm × 3.5 mm × 1.65 mm and features an exposed collector pad optimized for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input requiring −20 mA base drive to achieve full saturation at −100 mA collector current. |
| 2 | Collector (C) | Main high-voltage current path; electrically and thermally tied to pin 4 and exposed copper pad. |
| 3 | Emiter (E) | Reference terminal for PNP topology; connects to positive rail in high-side switch configurations. |
| 4 | Collector (C) | Duplicate collector terminal for parallel routing and improved thermal dissipation via dual PCB pads. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage blocking | −500 V VCESM rating enables direct interface with 380–400 VDC rectified mains in fluorescent ballasts and LED drivers. |
| Low VCEsat | −110 mV typical saturation voltage minimizes power loss (P = IC × VCEsat ≈ 11 mW at 100 mA), reducing thermal stress. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
| High hFE at high IC | hFE ≥ 10 at −250 mA pulsed ensures usable gain even near maximum rated current, easing base drive design. |
| Thermal robustness | Rth(j-sp) = 20 K/W enables 1.4 W dissipation with <30 °C rise above board temperature - critical for sealed LED modules. |
Applications
| Electronic Ballast | Automotive HID Lighting |
|---|---|
|
Use Scenario: High-frequency resonant switching in 220–240 VAC-fed fluorescent lamp ballasts. IC Role / Device Role / Timing Role: PNP high-side switch controlling lamp current during ignition and steady-state operation. Use Value: −500 V VCESM withstands voltage spikes during lamp strike; low VCEsat reduces thermal load in compact enclosed fixtures. |
Use Scenario: Ignition and regulation circuitry in automotive high-intensity discharge headlamps. IC Role / Device Role / Timing Role: Primary switching element in DC-DC boost converter driving HID arc tube. Use Value: AEC-Q101 qualification ensures reliability across −40 °C to +125 °C ambient; 150 °C Tj rating supports under-hood placement. |
| LED Chain Driver | Telecom Hook Switch |
|
Use Scenario: Constant-current switching stage for multi-string white LED arrays in commercial signage. IC Role / Device Role / Timing Role: Series-pass transistor regulating current through 10–20 V LED strings powered from 350 VDC bus. Use Value: −400 V VCEO rating safely isolates LED string from high-voltage supply; Rth(j-sp) = 20 K/W maintains <85 °C junction temp at 120 mA. |
Use Scenario: Line interface circuit in wired telephone systems for on-hook/off-hook detection and battery feed. IC Role / Device Role / Timing Role: High-voltage PNP switch connecting telephone line to battery feed network during off-hook state. Use Value: −500 V VCESM handles ringing voltage transients up to 120 VAC; low leakage (ICES < −100 nA) prevents false hook detection. |
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 |
|---|---|---|---|
| ON Semiconductor NSS12201LT1G | −400 V VCEO, −0.2 A IC, −200 mV VCEsat (typ), SOT-23 package | Limited to lower voltage/current; unsuitable for 400 VDC bus or automotive HID | Select only for cost-sensitive, non-automotive 200 V applications where footprint is critical. |
| Nexperia PBHV8540Z | NPN complement: +500 V VCESM, +0.25 A IC, +110 mV VCEsat (typ), same SOT223 package | Requires inverted drive logic and emitter-follower configuration; not drop-in replacement | Use when NPN topology simplifies gate drive or matches existing layout; verify base resistor recalculations. |
Compared with NSS12201LT1G, PBHV9040Z/ZLX delivers 100 V higher blocking and 2× current capability with superior thermal performance; versus PBHV8540Z, it enables high-side switching without level-shifting but requires negative base drive polarity.

FAQ
What is the maximum safe operating voltage for PBHV9040Z/ZLX in continuous DC applications?
The absolute maximum collector-emitter voltage with open base (VCEO) is −400 V. For reliable long-term operation, design should limit steady-state VCE to ≤ −320 V per the ICES test condition, ensuring margin against transients and derating over temperature and lifetime.
Can PBHV9040Z/ZLX be used in linear (analog) amplification mode?
No - this device is optimized for switching operation. Its hFE drops sharply above −100 mA, and VCEsat increases significantly beyond rated IC. The datasheet specifies no small-signal parameters (e.g., gm, rπ) or linearity metrics, confirming its intended use as a saturated switch only.
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 share the exposed copper pad. Layout must connect both pins to a common large-area copper pour (≥6 cm²) to achieve the specified 1.4 W power dissipation and 20 K/W Rth(j-sp); splitting them degrades thermal performance and risks overheating.
Is PBHV9040Z/ZLX compatible with lead-free reflow profiles?
Yes - the SC-73 package is qualified for standard JEDEC J-STD-020D lead-free reflow, with peak temperature up to 260 °C. The recommended footprint (Fig. 14) uses 4× 1.2 mm solder lands for pins 1–3 and 4× 1.3 mm for pin 4, ensuring robust wetting and mechanical reliability.
