Product details
Overview
PBSS4021SPN,115 from Nexperia is a dual NPN/PNP low VCE(sat) Breakthrough In Small Signal (BISS) transistor in SOT96-1 (SO8) package, rated for 20 V VCEO, 7.5 A NPN and −6.3 A PNP continuous collector current, with typical RCE(sat) of 25 mΩ (NPN) and 36 mΩ (PNP) at 5 A/−5 A. It serves as a high-efficiency power switch in battery-driven motor control and charging circuits.
For engineers reviewing the PBSS4021SPN,115 datasheet, PBSS4021SPN,115 pinout, PBSS4021SPN,115 application, or PBSS4021SPN,115 equivalent, this page delivers verified electrical specs, validated dual-transistor pin mapping, real-world loadswitch use cases, thermal derating curves, and confirmed alternative parts for NPN/PNP complementary switching designs.
Technical Context
This device integrates two independent BISS transistors - TR1 (NPN) and TR2 (PNP) - sharing no internal connection, enabling fully decoupled high-side and low-side switching. Each transistor features optimized base doping and epitaxial layer design to achieve ultra-low saturation resistance while maintaining high hFE (550 typ. at 500 mA for NPN; 400 typ. at −500 mA for PNP).
Switching performance is characterized by fast turn-on (ton = 80 ns NPN, 95 ns PNP) and controlled storage time (ts = 650 ns NPN, 340 ns PNP), supporting PWM frequencies up to 10 MHz in DC-DC and motor drive applications. Thermal resistance is specified per transistor (Rth(j-a) = 170 K/W on FR4 standard footprint) and per device (Rth(j-a) = 145 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 20 V (NPN), −20 V (PNP): Maximum safe blocking voltage across collector-emitter with base open. |
| IC | 7.5 A (NPN), −6.3 A (PNP): Continuous DC collector current rating under Tamb ≤25 °C with defined PCB mounting. |
| RCE(sat) | 25–35 mΩ (NPN), 36–54 mΩ (PNP) at IC = ±5 A / IB = ±0.5 A: Directly determines conduction loss and junction temperature rise in high-current switches. |
| hFE | 300–550 (NPN), 250–400 (PNP) at IC = ±500 mA: Enables low base drive current requirements for efficient gate driving in discrete H-bridge stages. |
| toff | 725 ns (NPN), 425 ns (PNP): Total turn-off delay + fall time; critical for minimizing shoot-through risk in synchronous rectification. |
| fT | 115 MHz (NPN), 105 MHz (PNP): Transition frequency confirming suitability for RF-coupled bias networks and high-speed switching control loops. |
| Ptot | 0.86 W (per device, FR4 standard footprint): Total dissipation limit defining maximum simultaneous power handling before thermal shutdown. |
Pinout & Package
SOT96-1 (SO8) is an 8-lead, 3.9 mm body-width surface-mount plastic package with gull-wing leads, optimized for medium-power thermal dissipation on FR4 PCBs. Pin 1 is index-marked; leads are spaced at 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (TR1, NPN) | Low-side return path for NPN transistor; connects to ground or low-voltage rail in half-bridge configurations. |
| 2 | Base (TR1, NPN) | Control input for NPN switch; requires ~0.5 A peak drive for full saturation at 7.5 A load. |
| 3 | Emitter (TR2, PNP) | High-side return path for PNP transistor; ties to load or positive rail in high-side switch topologies. |
| 4 | Base (TR2, PNP) | Inverted control input for PNP switch; negative current injection enables sourcing capability up to −6.3 A. |
| 5, 6 | Collector (TR2, PNP) | Power output terminal for PNP; paralleled pins reduce current density and thermal resistance in high-current paths. |
| 7, 8 | Collector (TR1, NPN) | Power output terminal for NPN; dual-collector layout supports 7.5 A continuous conduction with <275 mV VCE(sat). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VCE(sat) | 185–275 mV (NPN) and −235–−350 mV (PNP) at full rated current, reducing I²R losses by >40% vs. standard bipolar transistors. |
| High-current gain at high IC | hFE ≥250 (NPN) and ≥150 (PNP) at IC = ±4 A, enabling direct MCU GPIO drive without external buffer stages. |
| Dual-transistor integration | Independent NPN and PNP die in single SO8 package eliminate board space for discrete complementary pairs and improve thermal coupling consistency. |
| Optimized thermal footprint | Collector pins 5–8 occupy 60% of lead count and are thermally connected to large copper pads, achieving Rth(j-sp) = 40 K/W to solder point. |
Applications
| Motor Control | Battery Charging |
|---|---|
|
Use Scenario: Bidirectional 24 V DC brushed motor driver in portable power tools. IC Role / Device Role / Timing Role: PBSS4021SPN,115 provides complementary NPN/PNP switching in H-bridge legs, with TR1 sinking current during forward rotation and TR2 sourcing during reverse. Use Value: 25 mΩ RCE(sat) limits conduction loss to <1 W at 5 A, enabling compact heatsink-free design and extending runtime per charge cycle. |
Use Scenario: Constant-current/constant-voltage (CC/CV) lithium-ion charger for medical handheld devices. IC Role / Device Role / Timing Role: TR2 (PNP) acts as high-side pass transistor regulating charging current; TR1 (NPN) controls enable/disable sequencing and fault discharge path. Use Value: −350 mV VCE(sat) at −6.3 A ensures <2.2 W dissipation during CC phase, allowing precise 2 A charging with <±1% current error. |
| Power Management | Load Switching |
|
Use Scenario: Dual-rail power sequencer in industrial IoT gateway with 5 V and 3.3 V system rails. IC Role / Device Role / Timing Role: TR1 switches 5 V rail; TR2 switches 3.3 V rail; independent base control enables staggered startup and brown-out recovery. Use Value: 7.5 A/−6.3 A rating supports peak inrush currents up to 4 A per rail, eliminating need for external current-limiting resistors. |
Use Scenario: USB-C PD power delivery load switch in docking station with 20 V/3 A capability. IC Role / Device Role / Timing Role: TR1 (NPN) serves as low-side main switch; TR2 (PNP) handles reverse-polarity protection and hot-swap sequencing. Use Value: 15 A ICM peak rating withstands 10 ms inrush surges during connector mating, preventing false overcurrent trips. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary low-VCE(sat) transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LSD-13 | Single N-channel MOSFET (30 V, 25 mΩ, 12 A); no integrated PNP complement. | Requires external PNP or PMOS for high-side switching; lacks matched thermal tracking between N/P devices. | Select when only low-side switching is needed or when gate-drive simplicity outweighs dual-transistor integration benefits. |
| BC846BPDW1T1G | Complementary NPN/PNP pair (65 V, 100 mA, 400 mΩ); 10× lower current rating and 16× higher RCE(sat). | Limited to signal-level or pre-driver stages; unsuitable for direct load switching above 200 mA. | Choose only for low-power bias networks or logic-level translation where thermal performance is non-critical. |
Compared with DMN3025LSD-13 and BC846BPDW1T1G, PBSS4021SPN,115 uniquely delivers matched NPN/PNP saturation characteristics, dual 6–7 A current capability, and integrated thermal management in one SO8 package-enabling compact, high-efficiency power stage designs without discrete pairing compromises.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum base current is 1 A per transistor (Table 6). For reliable continuous operation at full collector current, IB = 0.375 A (NPN) and IB = −0.325 A (PNP) are recommended per datasheet Fig 9/17, ensuring VCE(sat) remains within 275 mV/−350 mV limits without thermal runaway.
Can PBSS4021SPN,115 be used in linear regulator applications?
No. Its RCE(sat) is optimized for saturated switching, not linear operation. At VCE = 2 V and IC = 5 A, power dissipation exceeds 10 W-far above the 0.86 W Ptot rating. Linear use would cause immediate thermal failure.
How does the dual-collector pin configuration affect PCB layout?
Pins 5–6 (PNP collector) and 7–8 (NPN collector) must be routed to separate high-current copper pours with ≥1 cm² area each, as specified in Table 6 footnote [2]. This reduces thermal resistance by 35% versus single-pin routing and prevents localized heating at solder joints.
Is the device RoHS-compliant and halogen-free?
Yes. PBSS4021SPN,115 meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21, with chlorine <900 ppm and bromine <900 ppm. Full compliance documentation is available via Nexperia's Quality Portal using 12NC 935687151115.
