Product details
Overview
PBSS302PD,115 from Nexperia is a PNP low VCEsat Breakthrough In Small Signal (BISS) transistor in SOT457 (SC-74) package, designed for high-efficiency power switching in compact DC-DC converters and MOSFET gate drivers. It delivers −40 V VCEO, −4 A continuous IC, 55–75 mΩ RCEsat at −6 A/−600 mA, and operates up to 150 °C junction temperature - enabling robust thermal performance in motor control and TFT backlight inverters.
For engineers reviewing the PBSS302PD,115 datasheet, PBSS302PD,115 pinout, PBSS302PD,115 application, or PBSS302PD,115 equivalent, key selection criteria include verified low saturation resistance, dual-collector thermal path design, pulsed current capability up to −15 A, and compatibility with FR4 PCB layouts using standard or extended collector pads.
Technical Context
This BISS transistor uses a proprietary epitaxial structure to achieve ultra-low VCEsat and RCEsat while maintaining high hFE (≥200 at −0.5 A). Its six-terminal SOT457 package integrates four collector leads (pins 1,2,5,6) for enhanced current handling and thermal dissipation - distinct from conventional 3-pin transistors.
Switching behavior is characterized by ton = 55 ns and toff = 321 ns under −10 V VCC, −2 A IC, and ±0.1 A base drive, supporting high-frequency operation in synchronous rectification and PWM-driven power stages without requiring external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −40 V: Maximum safe collector-emitter voltage with open base; defines blocking capability in high-side switch configurations. |
| IC (continuous) | −4 A: Continuous DC current rating at Tamb ≤25 °C on ceramic PCB; supports sustained load switching in battery-powered systems. |
| RCEsat | 55–75 mΩ at −6 A/−600 mA: Low conduction loss enables >95% efficiency in 12 V input DC-DC stages with minimal heatsinking. |
| hFE | ≥200 at −0.5 A: High DC current gain reduces required base drive current, easing microcontroller GPIO interface design. |
| toff | 321 ns: Fast turn-off time minimizes cross-conduction losses in half-bridge topologies operating above 100 kHz. |
| Tj max | 150 °C: Maximum junction temperature allows operation in sealed industrial enclosures without active cooling. |
| Ptot (FR4, 6 cm² pad) | 2.5 W: Total power dissipation with optimized PCB copper area; enables 1.1 W continuous operation on standard FR4 without thermal vias. |
Pinout & Package
Package: SOT457 (SC-74), surface-mount plastic package with six leads and integrated thermal path via four collector terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Collector | Four parallel collector connections reduce bond wire inductance and distribute current, lowering effective RCEsat and improving thermal spreading. |
| 3 | Base | Single base terminal for standard current-limited drive; compatible with 3.3 V/5 V logic-level microcontrollers via series resistor. |
| 4 | Emitter | Common emitter reference point; connects to ground or low-side return path in high-side switch applications. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RCEsat | 55–75 mΩ at −6 A enables <0.3 V drop in 5 A load switches, reducing heat generation by >40% vs. standard PNP transistors. |
| Dual thermal path layout | Four collector pins + large solder pad footprint provide Rth(j-a) as low as 113 K/W (FR4, 6 cm²), eliminating need for external heatsinks. |
| High peak current capability | −15 A single-pulse rating supports surge currents in motor startup and capacitor charging circuits without device failure. |
| Wide temperature operation | Specified from −65 °C to +150 °C ambient ensures reliability in automotive under-hood and industrial outdoor environments. |
| Low VBEsat | −0.84 to −1.1 V at −4 A simplifies base drive design and reduces power loss in driver stage compared to conventional bipolar devices. |
Applications
| Motor Control Switching | DC-DC Converter Synchronous Rectifier |
|---|---|
|
Use Scenario: Driving brushed DC motors in portable power tools with PWM frequencies up to 20 kHz. IC Role / Device Role / Timing Role: High-side PNP switch controlling motor supply rail; handles bidirectional current during regenerative braking. Use Value: 55 mΩ RCEsat limits conduction loss to <1.5 W at 5 A, enabling fanless enclosure design and extending battery runtime. |
Use Scenario: Secondary-side synchronous rectification in isolated 12 V → 3.3 V flyback converters for industrial IoT gateways. IC Role / Device Role / Timing Role: Low-loss replacement for Schottky diodes; driven by transformer-coupled gate signal synchronized to primary switch. Use Value: −320 mV VCEsat at −4 A cuts rectifier loss by 60% vs. 40 V/5 A Schottky, raising conversion efficiency from 82% to 89%. |
| TFT LCD Backlight Inverter | MOSFET Gate Driver Stage |
|

IC Role / Device Role / Timing Role: Fast-switching PNP transistor in resonant half-bridge output stage; commutates at 50–100 kHz. Use Value: 321 ns toff prevents shoot-through during dead-time transitions, ensuring stable lamp ignition and flicker-free operation. |
Use Scenario: Level-shifting and current amplification for driving high-capacitance N-channel MOSFETs in 24 V industrial PLC outputs. IC Role / Device Role / Timing Role: Active pull-down transistor in totem-pole gate driver; sinks ≥0.8 A peak base current during turn-off. Use Value: −1.1 V VBEsat at −4 A ensures full MOSFET enhancement even with 3.3 V MCU outputs, reducing gate drive loop inductance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low-VCEsat transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3005LPSQ-13 | −30 V VCEO, −5 A IC, 45 mΩ RCEsat; smaller DFN2020-6 package with no exposed collector pad. | Limited to ≤30 V systems; lower thermal mass restricts pulsed operation to <10 ms duty cycles. | Select when board space is critical and voltage stress remains below 25 V; verify PCB thermal relief for sustained 4 A loads. |
| BC807-40,115 | −45 V VCEO, −500 mA IC, 300 mΩ RCEsat; standard SOT23-3 package with single collector lead. | Insufficient current rating for motor or converter use; suitable only for signal-level switching or bias networks. | Use only for low-power logic interfacing or sensor conditioning where <100 mA load current suffices. |
Compared with DMTC3005LPSQ-13 and BC807-40,115, PBSS302PD,115 uniquely balances −40 V blocking, −4 A continuous current, and sub-75 mΩ RCEsat in a thermally optimized 6-lead package - making it the only viable option for compact, high-efficiency 12–24 V power switching without derating.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum continuous base current (IB) is −0.8 A per the datasheet limiting values table. Operation beyond this risks metallization electromigration and long-term parameter drift. For reliable 4 A collector current, a base drive of −400 mA (hFE ≈ 10) is recommended, staying well within the −0.8 A limit and providing margin for temperature-induced hFE degradation.
Can PBSS302PD,115 be used in linear regulator applications?
No - PBSS302PD,115 is not characterized or rated for linear-mode operation. Its RCEsat and thermal resistance specifications assume saturated switching conditions. Linear operation would exceed the 2.5 W Ptot limit at moderate VCE and IC, risking thermal runaway due to positive temperature coefficient of VCEsat. Use dedicated linear pass transistors instead.
How does the four-collector pin configuration affect PCB layout?
The four collector pins (1,2,5,6) must be routed to a common copper pour with minimum trace width of 1.5 mm and direct connection to internal ground/power planes. This configuration requires a custom footprint matching the SOT457 mechanical drawing - especially the 3.1 mm × 2.7 mm body and 0.95 mm pin pitch - to ensure uniform current sharing and avoid localized heating at any single bond wire.
Is PBSS302PD,115 compliant with AEC-Q101 for automotive use?
PBSS302PD,115 is not AEC-Q101 qualified. While its −65 °C to +150 °C operating range meets automotive ambient requirements, Nexperia's official qualification documentation confirms only specific variants (e.g., PBSS302PD-Q) carry AEC-Q101 certification. For automotive applications, consult Nexperia's qualified parts list and specify the -Q suffix variant.
