Product details
Overview
PBSS305PZ,135 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 path control. It delivers −80 V VCEO, −4.5 A IC, 61–87 mΩ RCE(sat) at −4 A/−200 mA, and operates up to 150 °C junction temperature-enabling compact, high-efficiency DC-DC converters and MOSFET gate drivers.
For engineers reviewing the PBSS305PZ,135 datasheet, PBSS305PZ,135 pinout, PBSS305PZ,135 application, or PBSS305PZ,135 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation value, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
This PNP BISS transistor uses optimized epitaxial base and emitter structures to achieve ultra-low saturation resistance while maintaining high current gain (hFE = 100 min at −4 A). Its dual-collector configuration (pins 2 and 4) enhances thermal dissipation on PCBs with extended copper pads.
It operates with fast switching performance: ton = 100 ns, toff = 285 ns, and fT = 100 MHz at −10 V VCE, supporting high-frequency power control without sacrificing saturation voltage efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - supports high-side switching in 48 V and 60 V industrial bus systems without derating |
| IC | −4.5 A continuous - enables direct drive of medium-power loads like fan motors or solenoids |
| RCE(sat) | 61–87 mΩ at −4 A/−200 mA - reduces conduction loss to <1.4 W at full load, minimizing heatsink need |
| hFE | 60–100 at −4 A - ensures stable base drive margin even under high-current, high-temperature conditions |
| Ptot | 1.7 W on FR4 with 6 cm² collector pad - allows use on standard PCBs without ceramic substrates |
| toff | 285 ns - supports PWM frequencies up to ~350 kHz in synchronous rectifier or gate driver applications |
| VBE(sat) | −0.93 to −1.05 V at −4 A/−400 mA - defines minimum base drive voltage required for full saturation |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with 4 leads and integrated heatsink capability; pins 2 and 4 are internally connected collectors for enhanced thermal transfer to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input requiring −225 mA for full −4.5 A saturation; driven by logic-level or dedicated gate driver |
| 2 | Collector | Main high-voltage current path terminal; electrically tied to pin 4 for parallel current handling and thermal spreading |
| 3 | Emiter | Reference node for load return; connects to system ground or positive rail depending on high-/low-side topology |
| 4 | Collector | Second collector terminal, internally bonded to pin 2-must be soldered to same copper pour for optimal Rth(j-a) |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | −245 to −345 mV at −4 A/−200 mA - cuts conduction loss by >50% vs. standard PNP transistors in same package |
| Dual-collector thermal design | Pins 2 & 4 share collector current and connect to large copper area - lowers Rth(j-a) to 74 K/W on FR4 |
| High hFE at high IC | hFE ≥ 60 at −4 A - reduces base drive power and simplifies driver stage design |
| 150 °C max junction temperature | Enables operation in under-hood automotive or enclosed industrial enclosures without forced cooling |
| Fast switching (toff = 285 ns) | Supports high-frequency DC-DC topologies where switching loss dominates over conduction loss |
Applications
| High-Voltage DC-DC Conversion | High-Voltage MOSFET Gate Driving |
|---|---|
|
Use Scenario: Step-down converter in 48 V telecom power supply delivering 12 V/3 A output. IC Role / Device Role / Timing Role: PNP switch in synchronous rectifier or active clamp circuit, operating at 250 kHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-current switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN2907A | VCEO = −60 V, IC = −600 mA, RCE(sat) ≈ 500 mΩ - lower voltage rating and 8× higher saturation resistance | Only suitable for ≤24 V, ≤0.5 A loads; cannot replace PBSS305PZ,135 in 48 V or high-current roles | Select only for legacy designs with strict footprint compatibility and sub-1 A requirements. |
| MMBT3906DW | Dual PNP in SOT363, VCEO = −40 V, IC = −200 mA per device - not rated for high-voltage or high-current operation | Limited to signal-level logic inversion or bias networks; unsuitable for power switching | Use only for dual low-power switching; avoid in any load-switching or gate-driving application. |
Compared with PN2907A and MMBT3906DW, PBSS305PZ,135 uniquely combines −80 V blocking, −4.5 A current, and sub-100 mΩ saturation resistance in a thermally enhanced SOT223 package-making it irreplaceable in high-efficiency, high-voltage discrete switching where both voltage headroom and conduction loss matter.

FAQ
What is the maximum safe operating voltage for PBSS305PZ,135?
The absolute maximum collector-emitter voltage (VCEO) is −80 V with open base. Operation above this rating risks avalanche breakdown and permanent damage. For reliable long-term use in 48 V systems, design with ≤80 % of VCEO (i.e., ≤64 V) to accommodate transients and temperature derating.
Can PBSS305PZ,135 replace an NPN transistor in the same circuit?
No-it is a PNP device with opposite polarity and complementary functionality. Swapping it for an NPN (e.g., PBSS305NZ) requires inverting the drive signal, reversing supply connections, and verifying bias network compatibility. Direct substitution will prevent proper switching or cause latch-up.
How should the dual collector pins (2 and 4) be connected on the PCB?
Pins 2 and 4 are internally shorted collectors and must be soldered to the same large copper pour-ideally ≥6 cm²-for optimal thermal performance. Splitting them across separate traces increases Rth(j-a) by up to 100 % and risks localized overheating at full −4.5 A load.
Is PBSS305PZ,135 qualified for automotive applications?
Yes-Nexperia specifies PBSS305PZ for automotive applications in its official data sheet (Section 1.3), and the device meets AEC-Q101 stress test requirements for discrete transistors. Its 150 °C Tj rating and −65 °C to +150 °C Tamb range support under-hood deployment in HVAC, lighting, and body control modules.
