Product details
Overview
PBHV9040Z-QF from Nexperia is a PNP high-voltage bipolar junction transistor (BJT) optimized for switching in high-voltage DC circuits, featuring −500 V collector-emitter peak voltage (VCESM), −0.25 A continuous collector current (IC), and low −110 mV typical VCEsat at IC = −100 mA / IB = −20 mA. It is qualified to AEC-Q101 and used in automotive motor management, LED chain drivers, and HID front lighting.
For engineers reviewing the PBHV9040Z-QF datasheet, PBHV9040Z-QF pinout, PBHV9040Z-QF application, or PBHV9040Z-QF equivalent, key selection criteria include verified high-voltage blocking capability, low saturation voltage under automotive ambient conditions, thermal resistance to solder point (Rth(j-sp) = 20 K/W), and SOT223 package compatibility with FR4 PCB heatsinking.
Technical Context
This PNP BJT employs epitaxial base technology to achieve high hFE (100–200 at IC = −50 mA) while sustaining −400 V VCEO and −500 V VCESM. Its low VCEsat is enabled by optimized emitter-base doping and thick collector drift region, supporting efficient switching in inductive loads up to 150 °C junction temperature.
Switching performance is characterized by 1819 ns typical turn-on time (ton) and 1800 ns turn-off time (toff) under VCC = −2 V, IC = −0.15 A, and IBoff = +0.03 A conditions. Transient thermal impedance data confirms stable operation under pulsed loads with duty cycles ≤ 0.75 on standard FR4 layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCESM | −500 V: Peak blocking voltage enables use in 400 V DC bus applications with safety margin. |
| VCEsat (typ) | −110 mV at IC = −100 mA / IB = −20 mA: Reduces conduction loss and self-heating in high-duty-cycle switching. |
| hFE (min) | 100 at VCE = −10 V, IC = −50 mA: Ensures reliable base drive margin across −55 °C to +125 °C ambient range. |
| Rth(j-sp) | 20 K/W: Enables direct thermal coupling to copper pour on FR4, critical for automotive under-hood thermal management. |
| Ptot (max) | 1.4 W at Tamb ≤ 25 °C with 6 cm² collector pad: Supports sustained power dissipation in compact SMT layouts. |
| fT | 55 MHz: Validates suitability for medium-frequency switching (e.g., <500 kHz SMPS) without excessive gate-drive complexity. |
Pinout & Package
The PBHV9040Z-QF is housed in an SC-73 (SOT223) plastic surface-mount package with 4 leads, 2.3 mm pitch, and integrated heatsink tab (lead 2 and 4 both connected to collector). Package dimensions are 6.5 mm × 3.5 mm × 1.65 mm with 6.7 mm × 3.7 mm outline footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal requiring −20 mA base current to saturate at −100 mA collector load; low-impedance drive needed. |
| 2 | Collector (C) | Main high-voltage current path; electrically and thermally tied to exposed metal tab for heatsinking. |
| 3 | Emitter (E) | Reference node for load return; must be routed with low-inductance trace in high-di/dt applications. |
| 4 | Collector (C) | Duplicate collector connection reinforcing thermal and electrical path to PCB copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use per stress test requirements including HTGB, HTRB, and temperature cycling. |
| Low VCEsat at high IC | −200 mV max at IC = −100 mA ensures <20 mW conduction loss per switch, reducing thermal design burden. |
| High hFE at elevated IC | Min 10 hFE at IC = −250 mA (pulsed) enables simplified base drive circuitry in high-current LED/HID ballasts. |
| Thermal robustness | Rth(j-a) = 89 K/W with 6 cm² collector pad meets ASIL-B thermal reliability targets for 15-year automotive life. |
Applications
| Electronic Ballast | Automotive Motor Management |
|---|---|
|
Use Scenario: High-frequency switching in fluorescent lamp ballasts operating from 300–400 V DC bus. IC Role / Device Role / Timing Role: Main PNP switch controlling resonant tank current; operates at 20–60 kHz with hard-switched turn-off. Use Value: −500 V VCESM prevents breakdown during inductive kickback; low VCEsat minimizes heat generation in sealed lamp housings. |

IC Role / Device Role / Timing Role: Primary switching transistor in buck-derived topology; handles repetitive 100–500 µs pulses at 100–500 kHz. Use Value: fT = 55 MHz supports clean switching edges; −100 nA ICBO at 150 °C prevents leakage-induced dimming drift. |
Use Scenario: Ignition pulse generator and main arc sustain switch in automotive HID headlamps. IC Role / Device Role / Timing Role: High-voltage switch delivering >20 kV ignition pulses and sustaining 85 V/3.5 A arc current. Use Value: −400 V VCEO rating exceeds HID lamp open-circuit voltage; 0.5 A ICM supports ignition surge current without second breakdown. |
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 |
|---|---|---|---|
| PHV9040Z-Q | Same die, non-automotive grade; no AEC-Q101 qualification; identical VCESM, VCEsat, and hFE specs. | Limited to industrial/non-safety-critical lighting or power supplies where automotive qualification is not required. | Select when cost sensitivity outweighs automotive compliance needs and lifecycle assurance is not mandated. |
| PBHV9040T-Q | SOT89 package (3-pin); no duplicate collector lead; Rth(j-a) = 120 K/W vs. 89 K/W; same electrical specs. | Suitable for lower-power LED drivers or telecom hook switches where PCB space is constrained but thermal demand is reduced. | Choose only if board layout prohibits SOT223 footprint and thermal load remains below 0.8 W continuous. |
Compared with PHV9040Z-Q and PBHV9040T-Q, PBHV9040Z-QF provides superior thermal performance via dual-collector SOT223 packaging and guaranteed automotive qualification-making it the sole choice for AEC-compliant high-power switching where junction temperature stability and long-term reliability are non-negotiable.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134. For continuous operation, derating begins at Tamb = 25 °C, with total power dissipation limited to 1.4 W on a 6 cm² FR4 collector pad. At 105 °C ambient, maximum continuous power drops to approximately 0.7 W to maintain Tj ≤ 150 °C.
Is PBHV9040Z-QF pin-compatible with NPN complement PBHV8540Z-Q?
No - PBHV9040Z-QF is a PNP device with base-emitter-collector pinout (1-B, 2-C, 3-E, 4-C), while PBHV8540Z-Q is an NPN with reversed polarity and identical SOT223 mechanical footprint but incompatible biasing and circuit topology. Direct substitution would invert switching logic and risk destruction.
Does the dual-collector configuration require separate PCB traces for pins 2 and 4?
No - pins 2 and 4 are internally shorted to the same collector node and designed to be soldered to a single large copper pour. Routing them separately defeats the thermal purpose; both must connect to the same heatsinking plane to achieve the specified Rth(j-sp) = 20 K/W.
Can PBHV9040Z-QF be used in linear amplification mode?
It is not recommended - the device is optimized for switching with low VCEsat and high-speed transitions, not linearity. Its hFE variation across IC (10–200) and significant VBEsat drift with temperature make it unsuitable for precision analog gain stages; dedicated linear transistors should be used instead.
