Product details
Overview
PBSS301PX,115 from Nexperia is a PNP low-VCE(sat) transistor in SOT89 package, rated for −12 V VCEO, −5.3 A IC, and 28 mΩ RCE(sat) at −4 A/−200 mA drive. It serves as a high-efficiency power switch in automotive-grade DC-DC converters, motor drivers, and charging circuits where thermal performance and board space are critical.
For engineers reviewing the PBSS301PX,115 datasheet, PBSS301PX,115 pinout, PBSS301PX,115 application, or PBSS301PX,115 equivalent, key selection criteria include verified AEC-Q101 qualification, pulsed RCE(sat) ≤ 40 mΩ, junction-to-solder-point thermal resistance of 20 K/W, and SOT89 footprint compatibility with FR4 or ceramic PCBs.
Technical Context
This device operates as a saturated-switching PNP transistor with fixed emitter-collector polarity and base-controlled conduction. Its design targets low-loss switching in 12 V automotive systems, supporting peak currents up to −10.6 A with pulse widths ≤1 ms and duty cycles ≤2%.
Thermal behavior is defined across three mounting conditions: standard FR4 (208 K/W Rth(j-a)), enhanced FR4 with 6 cm² collector pad (76 K/W), and Al₂O₃ ceramic (60 K/W). Junction temperature is limited to 150 °C, with storage and ambient ranges spanning −65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −12 V - Maximum allowable collector-emitter voltage with base open; defines safe blocking capability in 12 V rail applications. |
| IC | −5.3 A - Continuous DC collector current rating; supports sustained load switching in fan/motor control without derating at 25 °C. |
| RCE(sat) | 28 mΩ (typ) - Measured at −4 A IC/−200 mA IB; enables <112 mW conduction loss at full rated current. |
| hFE | 130–200 - DC current gain at −6 A IC/−300 mA IB; ensures robust saturation with moderate base drive in high-current switching. |
| VCE(sat) | −145 mV (typ) - At −5.3 A IC/−265 mA IB; confirms deep saturation for minimal voltage drop and heat generation. |
| toff | 325 ns - Turn-off time under −12.5 V VCC, −3 A IC, ±0.15 A base drive; suitable for PWM frequencies up to ~1 MHz. |
| AEC-Q101 | Qualified - Certified for automotive discrete semiconductor stress testing; validated for under-hood temperature cycling and humidity exposure. |
Pinout & Package
SOT89 (SC-62/TO-243) plastic surface-mount package: 3-lead, 1.5 mm pitch, 4.5 mm × 2.5 mm × 1.5 mm body; thermally optimized with exposed collector tab for solder-pad heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter | Current exit terminal; connected to system ground or low-side return path in high-side switch configurations. |
| 2 | Collector | Main power output terminal; electrically and thermally tied to PCB copper pour for heat dissipation and current routing. |
| 3 | Base | Control input; requires −265 mA drive for full saturation at −5.3 A; compatible with standard logic-level or dedicated gate drivers. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | −145 mV typical at −5.3 A ensures <0.8 W conduction loss, reducing heatsink requirements in space-constrained modules. |
| High IC capability | −5.3 A continuous rating enables direct replacement of larger TO-220 transistors in compact DC-DC and motor driver PCBs. |
| AEC-Q101 qualification | Validated for automotive use per stress test standard; eliminates need for additional qualification effort in Tier-1 designs. |
| Optimized thermal resistance | Rth(j-sp) = 20 K/W to solder point allows >2 W power dissipation on standard FR4 with 6 cm² collector pad. |
| Fast switching | 325 ns toff supports high-frequency PWM control in synchronous rectifiers and battery protection IC interfaces. |

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 |
|---|---|---|---|
| ON Semiconductor NSS30100PZT1G | VCEO = −12 V, IC = −3.5 A, RCE(sat) = 45 mΩ @ −2 A - lower current rating and higher saturation resistance. | Not qualified to AEC-Q101; limited to industrial/commercial temperature range (−55 °C to +150 °C). | Select when cost sensitivity outweighs automotive compliance and full 5.3 A capability. |
| Diodes Incorporated DXT30100P5-13 | VCEO = −12 V, IC = −5 A, RCE(sat) = 32 mΩ @ −4 A - slightly higher RCE(sat), same SOT89 package. | AEC-Q101 qualified but lacks published toff and thermal resistance data for ceramic PCB mounting. | Prefer for legacy designs already using Diodes Inc. supply chain; verify thermal performance in final layout. |
Compared with NSS30100PZT1G and DXT30100P5-13, PBSS301PX,115 delivers superior current handling and lower conduction loss while providing complete thermal characterization across FR4 and ceramic substrates-critical for production-ready automotive thermal modeling.

FAQ
What is the maximum allowable junction temperature for PBSS301PX,115?
The absolute maximum junction temperature is 150 °C, as specified in Table 5 (Limiting values). Operation beyond this limit risks permanent degradation of hFE and increased leakage. Derating curves in Figure 1 confirm 2.1 W total power dissipation is permissible only on ceramic PCBs at 25 °C ambient; FR4 mounting requires stricter thermal management.
Is PBSS301PX,115 pin-compatible with its NPN complement PBSS301NX,115?
No-PBSS301PX,115 (PNP) and PBSS301NX,115 (NPN) share identical SOT89 package dimensions and pin numbering (Emitter–Collector–Base), but their internal polarity and biasing requirements differ fundamentally. Direct substitution would invert circuit functionality and likely cause failure without redesign of base drive and load topology.
Does PBSS301PX,115 require a heatsink in standard FR4 PCB applications?
A dedicated heatsink is not required if the collector pad is implemented per Nexperia's recommended 6 cm² copper area (Table 5 footnote [2]). With that layout, Rth(j-a) drops to 76 K/W, allowing 1.65 W dissipation at 25 °C ambient. Without the extended pad, Rth(j-a) rises to 208 K/W, limiting usable power to ~0.6 W-insufficient for full 5.3 A operation.
Can PBSS301PX,115 be used in linear regulator applications?
No-it is optimized for saturated switching, not linear operation. Its Safe Operating Area (SOA) is not characterized for linear mode, and prolonged operation in the active region risks thermal runaway due to positive temperature coefficient of VCE(sat) and insufficient SOA margin at high VCE/IC combinations.
