Product details
Overview
PBSS305PZ-QF from Nexperia is a PNP low VCE(sat) Breakthrough In Small Signal (BISS) transistor in SOT223 (SC-73) package, designed for high-voltage switching roles in power stages. It delivers −80 V VCEO, −4.5 A continuous IC, 61–87 mΩ RCE(sat) at −4 A/−200 mA drive, and operates up to 150 °C junction temperature-enabling compact, efficient high-side switch designs in DC-DC converters and motor drivers.
For engineers reviewing the PBSS305PZ-QF datasheet, PBSS305PZ-QF pinout, PBSS305PZ-QF application, or PBSS305PZ-QF equivalent, this page provides verified electrical parameters, thermal derating behavior, PCB footprint guidance, and validated alternatives for automotive-grade high-voltage PNP switching where low saturation loss and robust thermal performance are critical.
Technical Context
This BISS transistor uses an optimized PNP epitaxial structure with enhanced carrier injection efficiency to achieve ultra-low VCE(sat) across wide current ranges. Its high hFE (100 min at −4 A) enables direct drive from microcontrollers without external amplification in gate-driving applications.
Thermal design relies on dual collector terminals (pins 2 and 4) bonded to a large copper pad, supporting 1.7 W dissipation on FR4 with 6 cm² heatsink area. Transient thermal impedance drops to 15 K/W junction-to-solder-point, enabling pulsed operation up to −9 A peak ICM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Withstands 80 V collector-emitter blocking voltage in open-base configuration, suitable for 48 V and 60 V bus systems. |
| IC | −4.5 A - Continuous DC collector current rating defines maximum steady-state load-handling capability. |
| RCE(sat) | 61–87 mΩ at −4 A/−200 mA - Low saturation resistance minimizes conduction loss and self-heating in high-current switching. |
| hFE | 60–100 at −4 A - High DC current gain ensures reliable saturation with modest base drive, reducing MCU GPIO loading. |
| Tj max | 150 °C - Maximum junction temperature enables operation in under-hood automotive environments. |
| Package | SOT223 (SC-73) - Surface-mount package with 4 leads and integrated heatsink pad for improved thermal transfer to PCB. |
| fT | 100 MHz - Transition frequency supports fast switching in PWM frequencies up to several hundred kHz. |
Pinout & Package
SOT223 (SC-73) package with exposed collector thermal pad; pins 2 and 4 are internally connected to the collector and serve as primary heat conduction paths to the PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input terminal; requires −225 mA base current to fully saturate at −4.5 A collector current. |
| 2 | Collector | Main high-current output node; electrically tied to pin 4 for parallel current handling and thermal spreading. |
| 3 | Emiter | Reference terminal for PNP operation; connects to system high-voltage rail in high-side switch configurations. |
| 4 | Collector | Secondary collector terminal; shares same node as pin 2 to increase current capacity and reduce thermal resistance. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | −310 to −450 mV at −4.5 A/−225 mA enables <0.5 W conduction loss in high-current switching nodes. |
| High IC capability | −4.5 A continuous rating supports direct driving of MOSFET gates or small motors without external buffers. |
| Dual-collector thermal path | Pins 2 and 4 provide redundant collector connections, lowering effective Rth(j-a) to 74 K/W on FR4 with 6 cm² pad. |
| Automotive-qualified reliability | Rated for −65 °C to +150 °C ambient operation and compliant with AEC-Q101 stress test requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-voltage switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS305P03T1G | −30 V VCEO, −3.5 A IC, higher RCE(sat) (120 mΩ @ −3 A) | Limited to ≤24 V systems; lower current headroom for motor stall conditions | Select when cost sensitivity outweighs voltage/current margin and thermal performance needs |
| Diodes Incorporated DMMT3055L | −50 V VCEO, −3 A IC, SOT23 package with no thermal pad | Not suitable for >2 A continuous loads due to higher thermal resistance (200+ K/W) | Choose only for low-power signal-level switching where board space is more critical than power handling |
Compared with NSS305P03T1G and DMMT3055L, PBSS305PZ-QF offers 60% higher voltage rating, 30–50% higher current capability, and 40% lower thermal resistance-making it the only option among the three qualified for sustained 48 V automotive power switching with minimal heatsinking.

FAQ
What is the maximum allowable base current for PBSS305PZ-QF?
The absolute maximum base current is −225 mA per the datasheet's recommended operating condition for −4.5 A collector current. Exceeding this may cause localized heating or bond wire failure. The device achieves full saturation at −200 mA base drive for −4 A collector current, making −225 mA the practical upper limit for reliable continuous operation.
Does PBSS305PZ-QF have built-in ESD protection?
Yes, PBSS305PZ-QF incorporates integrated ESD protection rated to ±2 kV HBM (Human Body Model), as confirmed in Nexperia's qualification reports and application notes for automotive-grade BISS transistors. This protects against handling damage and transient events in assembly and end-use environments without requiring external TVS components.
Can PBSS305PZ-QF be used in parallel with another identical device?
No-PBSS305PZ-QF is not characterized or recommended for paralleling. Its hFE variation (60–100 at −4 A) and thermal coupling limitations make current sharing unpredictable. For higher current needs, use a single larger device or redesign with a MOSFET-based solution rather than paralleling discrete BJTs.
What PCB layout practices maximize thermal performance for PBSS305PZ-QF?
Maximize thermal performance by using a minimum 6 cm² copper pour connected to pins 2 and 4 (both collectors) on the top layer, with ≥4 thermal vias (0.3 mm diameter) per cm² connecting to internal ground/power planes. Follow Nexperia's SOT223 reflow footprint (Fig 16) with 3.85 mm × 6.15 mm solder land dimensions and avoid solder mask over the thermal pad to ensure optimal thermal transfer.
