Product details
Overview
PBHV9040Z 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 chain drivers, HID front lighting, and automotive motor management systems.
For engineers reviewing the PBHV9040Z datasheet, PBHV9040Z pinout, PBHV9040Z application, or PBHV9040Z equivalent, key selection criteria include its AEC-Q101 qualification, SOT223 thermal performance (Rth(j-sp) = 20 K/W with 6 cm² collector pad), low VCEsat enabling <0.5 W dissipation at rated current, and verified operation up to 150 °C junction temperature.
Technical Context
This PNP BJT employs epitaxial planar technology optimized for high-voltage blocking and low-saturation operation. Its structure supports stable hFE ≥100 at −50 mA and retains usable gain (hFE ≥10) even at −250 mA pulsed current, enabling reliable switching control across wide temperature ranges (−55 °C to +150 °C).
The device operates with open-base VCEO = −400 V and exhibits low leakage: ICBO ≤ −10 µA at Tj = 150 °C and ICES ≤ −100 nA at VCE = −320 V. Switching performance is characterized by ton = 1819 ns and toff = 1800 ns under standardized test conditions (VCC = −2 V, IC = −0.15 A), supporting kHz-range SMPS and ballast control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCESM | −500 V peak - enables direct interface with 400 V DC bus without external snubbing in LED/HID drivers |
| VCEsat (typ) | −110 mV at IC = −100 mA/IB = −20 mA - reduces conduction loss to <11 mW, critical for thermally constrained PCB layouts |
| hFE (min) | 100 at VCE = −10 V, IC = −50 mA - ensures sufficient DC gain for simple resistor-biased gate drive in automotive hook switches |
| Ptot (max) | 1.4 W with 6 cm² copper pad - delivers 2.8× higher power handling than standard SOT223 footprint, supporting sustained 250 mA operation |
| Rth(j-sp) | 20 K/W - enables rapid heat transfer from junction to solder point, improving transient thermal response in pulsed LED dimming |
| fT | 55 MHz - supports fast switching in >100 kHz SMPS topologies without gain roll-off limiting control loop bandwidth |
| IEBO | ≤ −100 nA at VEB = −4 V - guarantees minimal base leakage during off-state, preserving system-level standby current budgets |
Pinout & Package
Package: SC-73 (SOT223) medium-power surface-mount plastic package with 4 leads, 2.3 mm pitch, and integrated heatsink tab (lead 2 and 4 both connected to collector). Dimensions: 6.5 mm × 3.5 mm × 1.65 mm body; mounting pad for collector requires 6 cm² copper area for full 1.4 W rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input node; requires −20 mA base drive for full saturation at 100 mA collector current |
| 2 | Collector (C) | Main high-voltage current path; electrically tied to exposed thermal pad for enhanced heatsinking |
| 3 | Emitter (E) | Reference terminal for load return; connects to system ground or positive rail depending on high-side configuration |
| 4 | Collector (C) | Duplicate collector terminal - must be soldered to same net as pin 2 to maintain thermal and electrical integrity |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive motor management and lighting per stress test requirements - eliminates need for additional qualification testing |
| Low VCEsat | −110 mV typ. at rated current - cuts conduction losses by >60% vs. standard PNP transistors, directly extending thermal margin |
| High hFE at high IC | hFE ≥25 at IC = −250 mA (pulsed) - enables efficient drive with minimal base current, reducing driver-stage component count |
| Enhanced thermal resistance | Rth(j-sp) = 20 K/W - allows 30% higher ambient temperature operation vs. legacy SOT223 devices under identical PCB layout |
| High-voltage isolation | VCBO = −500 V - supports direct connection to 380 VAC rectified rails without series voltage dividers or protection networks |

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, SOT23 package - lower voltage rating but higher current capability | Not suitable for >400 V bus applications; limited to 12/24 V automotive loads | Select only when system voltage ≤60 V and peak current >0.5 A is required |
| BCP53-16 | −45 V VCEO, −1 A IC, SOT223 package - lacks AEC-Q101 qualification and has VCEsat ≈ −300 mV | Acceptable for non-automotive fluorescent ballasts but fails automotive thermal and reliability requirements | Use only in cost-sensitive industrial lighting where AEC-Q101 and low VCEsat are not mandatory |
Compared with PHPT60303SQ and BCP53-16, PBHV9040Z uniquely combines automotive-grade reliability, −500 V blocking, and sub-120 mV saturation in a thermally enhanced SOT223, making it irreplaceable in 400 V LED/HID systems requiring long-term stability.

FAQ
What is the maximum safe operating voltage for PBHV9040Z in continuous DC applications?
The PBHV9040Z is rated for −400 V collector-emitter voltage (VCEO) with open base, meaning it can safely block up to 400 V DC continuously. For transient surges, its −500 V VCESM rating applies only under specified pulse conditions (VBE = 0 V), not steady-state operation.
Can PBHV9040Z replace NPN transistors like PBHV8540Z in the same circuit?
No - PBHV9040Z is a PNP device and PBHV8540Z is its NPN complement; they are not interchangeable without redesigning biasing, polarity, and current flow paths. Swapping requires reversing supply connections, inverting drive signals, and recalculating base resistors to maintain proper saturation.
How does the dual-collector pin configuration (pins 2 and 4) affect PCB layout?
Pins 2 and 4 are internally connected to the same collector node and must be soldered to the same copper pour - typically an extended thermal pad. This dual-pin arrangement improves current sharing and thermal spreading; splitting them across separate nets causes uneven current distribution and localized overheating.
Is PBHV9040Z suitable for linear regulator applications?
While capable of linear operation, PBHV9040Z is optimized for switching use. Its low VCEsat and high hFE at high current support efficient saturated switching, but its SOA (Safe Operating Area) limits linear dissipation - continuous operation above 0.5 W requires aggressive heatsinking beyond standard SOT223 footprints.
