Product details
Overview
PBSS4032PZ,115 from Nexperia is a PNP low VCE(sat) Breakthrough In Small Signal (BISS) transistor in SOT223 (SC-73) package, rated for −30 V VCEO, −4.4 A IC, and 58–86 mΩ RCE(sat) at −4 A/−400 mA drive. It delivers high hFE up to 350 at −500 mA and supports fast switching with ton = 90 ns and toff = 220 ns. Used in DC-to-DC converters where low conduction loss and thermal efficiency are critical.
For engineers reviewing the PBSS4032PZ,115 datasheet, PBSS4032PZ,115 pinout, PBSS4032PZ,115 application, or PBSS4032PZ,115 equivalent, key selection criteria include verified VCE(sat) ≤ −345 mV at −4 A, AEC-Q101 qualification for automotive-grade reliability, thermal resistance Rth(j-a) as low as 65 K/W on ceramic PCB, and confirmed 4-pin SOT223 pinning with dual collector terminals.
Technical Context
This PNP BISS transistor uses optimized epitaxial base and emitter structures to achieve ultra-low saturation voltage while maintaining high current gain across wide operating ranges. Its dual-collector configuration (pins 2 and 4) enables enhanced thermal dissipation and current handling beyond standard SOT223 transistors.
It operates with VEB ≤ −5 V and Tj up to 150 °C, supporting robust performance in power management circuits under transient load conditions. The device's fT of 130 MHz and Cc of 65 pF confirm suitability for medium-frequency switching applications up to several hundred kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −30 V - Maximum safe blocking voltage with base open; defines upper limit for DC-to-DC converter input stage selection. |
| IC | −4.4 A - Continuous collector current rating; supports high-current battery charging paths without forced cooling. |
| RCE(sat) | 58–86 mΩ at −4 A/−400 mA - Directly determines conduction loss (Ploss = I² × R); enables >95% efficiency in compact 5–12 V buck stages. |
| hFE | 60–350 - DC current gain varies with IC; ensures stable base drive design from light-load (−500 mA) to full-load (−4 A) operation. |
| toff | 220 ns - Total turn-off time under VCC = −12.5 V, IC = −1 A; limits minimum achievable switching period in PWM controllers. |
| AEC-Q101 | Qualified - Validated for automotive temperature range (−40 °C to +125 °C ambient) and mechanical stress; suitable for under-hood power modules. |
Pinout & Package
The PBSS4032PZ,115 is housed in a 4-lead SOT223 (SC-73) plastic surface-mount package with an extended copper pad for thermal enhancement. Pins 2 and 4 are internally connected to the collector, enabling parallel routing for lower inductance and improved heat spreading on PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal requiring −400 mA base drive for full saturation at −4 A; low VBE(sat) (−0.99 V) reduces driver power loss. |
| 2 | Collector | Main high-current output path; electrically identical to pin 4; used for primary PCB trace connection and thermal pad anchoring. |
| 3 | Emiter | Reference node tied to system ground or positive rail in high-side switch configurations; handles full load current with minimal voltage drop. |
| 4 | Collector | Redundant collector terminal; enables symmetric layout, dual-sided copper pour, and reduced thermal impedance when both pins are soldered to large copper areas. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | −230 mV typical at −4 A/−400 mA - cuts conduction losses by ~40% vs. conventional PNP transistors, reducing heatsink requirements. |
| Dual collector terminals | Pins 2 & 4 - Enable 2× current-carrying capacity per lead and reduce effective thermal resistance by distributing heat across two PCB pads. |
| High hFE at high IC | 100 min at −4 A - Allows simplified base drive circuitry with lower gate-driver current demand and smaller bias resistors. |
| AEC-Q101 qualification | Validated for automotive use - Ensures reliability under temperature cycling, humidity, and mechanical vibration per industry-standard stress tests. |
| Optimized switching speed | ton/toff = 90/220 ns - Supports PWM frequencies up to 500 kHz without excessive switching loss, ideal for space-constrained portable chargers. |
Applications
| DC-to-DC Converters | Battery Charging Circuits |
|---|---|
|
Use Scenario: Step-down (buck) conversion in automotive infotainment power supplies delivering 3.3 V/2 A from 12 V battery. IC Role / Device Role / Timing Role: High-side PNP switch controlling energy transfer to output inductor; operates at 250 kHz PWM with <100 ns dead-time margin.

IC Role / Device Role / Timing Role: Precision current-regulating pass element in constant-current (CC) phase; biased via op-amp feedback loop. Use Value: Stable hFE ≥ 100 at −2 A ensures ±2% current regulation accuracy over temperature; low VBE(sat) minimizes op-amp output swing requirement. |
| Power Management ICs | Load Switches in Portable Devices |
|
Use Scenario: Secondary-side synchronous rectification enable switch in isolated flyback adapters for medical IoT sensors. IC Role / Device Role / Timing Role: Fast-turning PNP gate driver for N-channel MOSFET; triggered by transformer auxiliary winding timing signal. Use Value: toff = 220 ns allows clean turn-off before next cycle, preventing shoot-through; −30 V VCEO accommodates reflected voltage spikes. |
Use Scenario: System-level load switch isolating backup battery from main PMIC during deep-sleep mode in asset trackers. IC Role / Device Role / Timing Role: Low-leakage (ICES ≤ −100 nA) high-current disconnect switch controlled by microcontroller GPIO.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low VCE(sat) transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3005LPSQ-13 | N-channel MOSFET (30 V, −5.3 A), requires gate driver; RDS(on) = 32 mΩ @ VGS = −4.5 V | Not directly pin-compatible; needs level-shifting for high-side use; superior RDS(on) but higher gate charge | Select when designing new high-efficiency topologies with available gate drive resources; not drop-in for existing BJT-based layouts. |
| PBSS4041PZ,115 | PNP BISS variant: −40 V VCEO, −4.1 A IC, RCE(sat) = 70–105 mΩ - higher voltage rating, slightly lower current and higher saturation resistance | Same SOT223-4 package and pinout; AEC-Q101 qualified; suitable for 24 V systems where −30 V margin is insufficient | Choose for 24 V automotive subsystems requiring extended blocking capability; trade-off is +15% conduction loss at same current. |
Compared with PBSS4032PZ,115, DMT3005LPSQ-13 offers lower on-resistance but demands added gate-drive complexity, while PBSS4041PZ,115 provides higher voltage headroom at the cost of increased RCE(sat) - making PBSS4032PZ,115 optimal for cost-sensitive, thermally constrained 12 V DC-DC designs.

FAQ
What is the maximum continuous collector current for PBSS4032PZ,115?
The maximum continuous collector current (IC) is −4.4 A at Tamb ≤ 25 °C on FR4 PCB with standard footprint. Derating applies above 25 °C ambient: power dissipation drops linearly to zero at 150 °C junction temperature, with Rth(j-a) = 180 K/W limiting usable current in still-air conditions.
Is PBSS4032PZ,115 suitable for automotive applications?
Yes - it is fully AEC-Q101 qualified for discrete semiconductors, tested across temperature cycling, humidity, mechanical shock, and ESD. Its guaranteed operation from −40 °C to +125 °C ambient and 150 °C junction temperature meets automotive under-hood requirements for body control modules and ADAS power rails.
How does the dual-collector configuration improve thermal performance?
Pins 2 and 4 are internally shorted collector terminals, allowing simultaneous connection to large copper pours on both sides of the PCB. This doubles effective thermal path area, reducing Rth(j-a) from 180 K/W (standard FR4) to 65 K/W (ceramic PCB), enabling 2.4× higher power dissipation before reaching 150 °C junction limit.
What is the typical VCE(sat) at 4 A collector current?
At IC = −4 A and IB = −400 mA, VCE(sat) is typically −230 mV (max −345 mV), measured per pulse test conditions (tp ≤ 300 μs, duty cycle ≤ 0.02). This value is confirmed in Table 7 of the official Nexperia datasheet Rev. 01 (2010).
