Product details
Overview
BF723-QX from Nexperia is a PNP high-voltage bipolar junction transistor in SOT223 (SC-73) package, rated for VCEO = −250 V, IC = −100 mA, and hFE ≥ 50 at −25 mA/−20 V; designed for high-voltage switching and linear amplification in automotive-grade power control circuits.
For engineers reviewing the BF723-QX datasheet, BF723-QX pinout, BF723-QX application, or BF723-QX equivalent, key selection criteria include verified AEC-Q101 qualification, low feedback capacitance (Cre = 2.5 pF), thermal resistance to solder point (Rth(j-sp) = 25 K/W), and dual-collector SOT223 layout enabling enhanced heatsinking in space-constrained HV designs.
Technical Context
This device operates as a high-voltage PNP switch with open-base collector-emitter breakdown of −250 V and peak collector current capability of −200 mA. Its DC current gain (hFE) is specified ≥50 under −25 mA/−20 V conditions, and saturation voltage is ≤−0.6 V at −30 mA/−5 mA drive.
Thermal performance is defined for PCB mounting with 1 cm² single-sided copper pad: Rth(j-a) = 106 K/W and Rth(j-sp) = 25 K/W. Cut-off leakage is tightly controlled - ICBO ≤ −10 nA at −200 V/25 °C and ≤ −10 µA at 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −250 V: Maximum safe collector-emitter voltage with base open; enables use in >200 V DC bus switching. |
| IC | −100 mA continuous: Rated collector current defines steady-state load handling capacity. |
| hFE | ≥50 at −25 mA/−20 V: Ensures reliable base drive margin for switching applications. |
| VCE(sat) | ≤−0.6 V at −30 mA/−5 mA: Limits conduction loss and self-heating during saturation. |
| Cre | 2.5 pF at −30 V: Low feedback capacitance supports stable high-frequency operation up to 60 MHz fT. |
| Rth(j-sp) | 25 K/W: Junction-to-solder-point thermal resistance enables direct thermal path to PCB copper. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with 4 leads, 2.3 mm pitch, 6.5 mm × 3.5 mm × 1.65 mm body, and integrated heatsink pad on collector terminals (pins 2 and 4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal for biasing; requires current-limited drive to ensure hFE-based operation. |
| 2 | Collector (C) | Primary high-voltage output node; electrically and thermally connected to heatsink pad. |
| 3 | Emitter (E) | Reference terminal for PNP topology; tied to higher potential rail in typical switch configuration. |
| 4 | Collector (C) | Duplicate collector terminal for improved current sharing and thermal dissipation via second PCB pad. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature range (−65 °C to +150 °C) and reliability stress testing. |
| Low feedback capacitance | Cre = 2.5 pF minimizes Miller effect, supporting stable switching up to 60 MHz fT. |
| Dual-collector SOT223 | Pins 2 and 4 both connect to collector, doubling thermal interface area and reducing Rth(j-sp). |
| High VCEO rating | −250 V enables direct interface with industrial 200 V DC lines without external snubbing. |
Applications
| Automotive Door Lock Actuator | Industrial HV Sensor Bias Supply |
|---|---|
Use Scenario: Driving solenoid loads in 12 V/24 V automotive door modules with transient spikes up to 150 V. IC Role / Device Role / Timing Role: PNP high-side switch controlling ground-return solenoid current. Use Value: −250 V VCEO withstands load-dump transients; AEC-Q101 ensures field reliability over 15-year vehicle life. | Use Scenario: Providing stable −100 mA bias current to avalanche photodiode (APD) arrays in industrial laser sensors. IC Role / Device Role / Timing Role: Linear current source with low noise and tight hFE consistency. Use Value: ICBO ≤ −10 nA at 25 °C ensures minimal dark-current error; low Cre prevents signal coupling in high-gain analog stages. |
| LED Driver for Street Lighting | AC-DC Auxiliary Supply Switch |
Use Scenario: High-voltage series pass element in constant-current LED driver for 100–277 V AC input systems. IC Role / Device Role / Timing Role: Linear regulator pass transistor dissipating up to 1.2 W. Use Value: Ptot = 1.2 W with Rth(j-sp) = 25 K/W allows direct PCB heatsinking-no external heatsink required at <1 W dissipation. | Use Scenario: Primary-side switch in auxiliary flyback supply powering control ICs in industrial SMPS. IC Role / Device Role / Timing Role: High-voltage start-up switch activated during initial power-up. Use Value: Dual-collector layout improves thermal cycling endurance under repeated surge stress; −200 mA ICM handles startup inrush safely. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-voltage transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BF722-Q | NPN complement; same package, VCEO = −250 V, IC = −100 mA, but opposite polarity and drive logic. | Requires inverted control signal and emitter-follower vs. common-emitter topology. | Select when NPN high-side or low-side switching fits system-level bias architecture. |
| MJD2955T4G | TO-220 package; VCEO = −60 V, IC = −10 A, higher power but lower voltage rating and no AEC-Q101 qualification. | Used in high-current, low-voltage linear regulators-not suitable for >100 V transient environments. | Choose only for non-automotive, high-current, low-voltage thermal management where SOT223 footprint is insufficient. |
Compared with BF722-Q and MJD2955T4G, BF723-QX uniquely combines automotive qualification, −250 V capability, and dual-collector SOT223 thermal design-making it irreplaceable for compact, high-reliability HV switching where voltage margin and board-level heatsinking are critical.

FAQ
Is BF723-QX pin-compatible with standard SOT223 PNP transistors?
No-BF723-QX uses a 4-pin SC-73 (SOT223) variant with two collector pins (2 and 4), unlike conventional 3-pin SOT223. PCB layout must allocate separate pads for both collectors to achieve rated thermal and current performance.
What is the maximum allowable PCB copper area for optimal thermal performance?
For Rth(j-sp) = 25 K/W, Nexperia specifies a 1 cm² single-sided copper pad, tin-plated, dedicated to the collector terminals. Increasing pad area beyond this yields diminishing returns unless multilayer thermal vias are added.
Does BF723-QX support pulsed operation above its continuous IC rating?
Yes-peak collector current ICM is rated at −200 mA. Operation within this limit requires duty cycle and pulse width constraints per Nexperia's Safe Operating Area (SOA) curves to avoid secondary breakdown or thermal runaway.
Can BF723-QX replace BF723 in existing designs?
BF723-QX is the automotive-qualified (AEC-Q101) version of BF723. It shares identical electrical specs and pinout but adds stress-test validation for automotive use. Drop-in replacement is permitted if AEC compliance is required; otherwise, standard BF723 remains acceptable for non-automotive applications.
