Product details
Overview
PBSS301PD,115 from Nexperia is a dual NPN low-VCE(sat) transistor in SOT457 (SC-74) package, with 100 V VCEO, 1 A IC, and typical VCE(sat) of 90 mV at IC = 500 mA and IB = 50 mA. It serves as a high-efficiency switching element in DC-DC converter output stages and LED driver current paths.
For engineers reviewing the PBSS301PD,115 datasheet, PBSS301PD,115 pinout, PBSS301PD,115 application, or PBSS301PD,115 equivalent, key selection criteria include saturation voltage matching, dual-transistor thermal coupling, SOIC-6 footprint compatibility, and 100 V breakdown margin for industrial 24–48 V rail designs.
Technical Context
This device integrates two matched NPN transistors on a single die to minimize parameter variation and thermal drift between channels. Its low 90 mV VCE(sat) reduces conduction loss in high-current switching nodes, while the 100 V VCEO rating supports operation across 24 V, 36 V, and 48 V industrial bus systems.
The SOT457 package provides 1.5 W power dissipation capability with low thermal resistance (Rth(j-a) = 125 K/W), enabling stable dual-channel operation without external heatsinking in ambient temperatures up to +85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - supports 48 V industrial bus with 108 % safety margin against transients |
| IC | 1 A continuous - enables 500 mA per channel in dual-switch configurations |
| VCE(sat) | 90 mV typ. @ IC=500 mA, IB=50 mA - cuts conduction loss by ~55 % vs. standard 200 mV devices |
| hFE | 160 min. @ IC=500 mA - ensures reliable base drive margin with 5 V logic-level control |
| Ptot | 1.5 W - allows dual-channel operation at full load without forced air cooling |
| Rth(j-a) | 125 K/W - enables junction temperature rise of ≤125 °C at 1.5 W in still air |

| 4 | Collector 2 | High-current output node for second channel; electrically isolated from Pin 3 |
| 5 | Base 2 | Control input for second transistor; matched gain and threshold to Pin 2 |
| 6 | Emitter 2 | Low-side return path for second transistor channel; internally tied to Pin 1 in some variants but not this part |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN with matched hFE and VCE(sat) | ΔhFE ≤ 15 %, ΔVCE(sat) ≤ 10 mV - ensures balanced current sharing in parallel or push-pull topologies |
| Low 90 mV VCE(sat) | Reduces power loss to 45 mW per channel at 500 mA - extends thermal headroom in compact layouts |
| 100 V VCEO rating | Withstands ISO 7637-2 Pulse 1/2b transients on 48 V buses without clamping circuitry |
| SOT457 thermal pad | Enables 1.5 W dissipation with PCB copper area ≥ 100 mm² - eliminates need for discrete heatsinks |
Applications
| Industrial DC-DC Converters | LED Constant-Current Drivers |
|---|---|
Use Scenario: Synchronous buck converter output stage operating from 48 V input to 5–24 V output at 1–2 A. IC Role / Device Role / Timing Role: Low-side switch pair controlling inductor discharge path and freewheeling current. Use Value: 90 mV VCE(sat) reduces conduction loss by 110 mW per channel versus 200 mV alternatives, improving efficiency by 0.8 % at full load. | Use Scenario: Multi-string LED driver with individual current regulation per string using PWM dimming. IC Role / Device Role / Timing Role: Dual-channel current sink switching each LED string on/off synchronously with MCU GPIO. Use Value: Matched VCE(sat) ensures uniform brightness across strings; 100 V rating accommodates open-circuit LED string detection. |
| Programmable Logic Output Modules | Motor Control H-Bridge Pre-drivers |
Use Scenario: PLC digital output module driving 24 V solenoids or relays with overcurrent protection. IC Role / Device Role / Timing Role: Dual low-side switches interfacing FPGA or microcontroller outputs to inductive loads. Use Value: Integrated dual structure simplifies PCB layout and reduces component count versus discrete transistors; 100 V rating handles 24 V inductive kickback. | Use Scenario: Half-bridge gate driver stage controlling external N-channel MOSFETs in 24 V BLDC motor inverters. IC Role / Device Role / Timing Role: Low-side pre-driver providing controlled turn-on/turn-off current to MOSFET gates. Use Value: Low VCE(sat) minimizes driver-stage loss; matched hFE ensures consistent gate charge timing across both legs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-VCE(sat) NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBT3904DW1T1G | VCEO = 40 V, VCE(sat) = 200 mV @ IC=50 mA - lower voltage rating and higher saturation loss | Restricted to ≤24 V systems; unsuitable for 48 V bus transient immunity | Select only for cost-sensitive 12–24 V logic-level switching where efficiency is secondary |
| DMN3020LSD-13 | Single N-channel MOSFET, RDS(on) = 28 mΩ @ VGS=10 V - different topology, no bipolar drive requirement | Requires 10 V gate drive; lacks inherent current-matching of dual bipolar die | Prefer for high-frequency (>100 kHz) switching where gate charge matters more than thermal coupling |
Compared with MBT3904DW1T1G and DMN3020LSD-13, PBSS301PD,115 uniquely delivers 100 V capability, sub-100 mV saturation, and monolithic dual matching-making it optimal for thermally coupled, medium-voltage industrial switching where bipolar drive simplicity and loss minimization are critical.

FAQ
What is the maximum allowable junction temperature for PBSS301PD,115?
The absolute maximum junction temperature is 150 °C per Nexperia's datasheet. Derating begins at 85 °C ambient; at 1.5 W total dissipation, the junction-to-ambient thermal resistance of 125 K/W limits usable ambient temperature to 35 °C unless PCB copper area exceeds 200 mm² or airflow is added.
Can PBSS301PD,115 be used in linear mode for analog current regulation?
No-it is optimized for switching operation only. Its low VCE(sat) and narrow safe operating area (SOA) make it unsuitable for sustained linear-mode bias; continuous operation above 100 mA at VCE > 2 V risks thermal runaway due to positive temperature coefficient of VCE(sat).
Is the emitter connection shared between the two transistors in PBSS301PD,115?
No. Pins 1 and 6 are independent emitters with separate internal connections. Unlike some dual-transistor packages (e.g., PBSS4041PAS), PBSS301PD,115 provides fully isolated dual NPN structures-enabling independent control, floating configurations, and true push-pull or half-bridge use without level-shifting.
Does PBSS301PD,115 require a base resistor when driven by a 3.3 V microcontroller GPIO?
Yes. With hFE ≥ 160 at IC = 500 mA, a minimum base current of 3.1 mA is required. A 1 kΩ resistor limits GPIO current to 3.3 mA at 3.3 V, ensuring saturation while staying within typical MCU output capability; values below 820 Ω risk exceeding GPIO sink limits.
