Product details
Overview
PBSS5255PAPSX from Nexperia is a PNP/PNP low VCEsat (BISS) double transistor in DFN2020D-6 (SOT1118D) package, designed for high-efficiency load switching with −55 V VCEO, −2 A continuous IC, and −300 mV typical VCEsat at IC = −0.7 A / IB = −7 mA. It serves as dual high-current switch in battery-powered power management and LED lighting circuits.
For engineers reviewing the PBSS5255PAPSX datasheet, PBSS5255PAPSX pinout, PBSS5255PAPSX application, or PBSS5255PAPSX equivalent, this page delivers verified electrical specs, thermal derating curves, dual-transistor terminal mapping, and AOI-compatible SMT mounting guidance for compact DC-DC and charging circuit design.
Technical Context
This dual PNP BISS transistor integrates two matched high-gain, low-saturation transistors sharing a thermally enhanced DFN2020D-6 package with side-wettable flanks. Each transistor supports independent operation with open-base VCEO = −55 V and peak ICM = −3 A under 1 ms pulses.
Its BISS architecture delivers hFE = 50–75 at IC = −2 A and VCE = −2 V, with RCEsat as low as 250 mΩ at IC = −1 A / IB = −50 mA - enabling minimal conduction loss in space-constrained load-switching nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −55 V per transistor: maximum safe collector-emitter blocking voltage with base open, defining system-level overvoltage margin in battery disconnect applications. |
| IC | −2 A continuous: rated DC collector current per transistor, supporting sustained 2 A load switching without forced cooling on standard FR4 PCBs. |
| VCEsat | −300 to −420 mV at IC = −0.7 A / IB = −7 mA: ultra-low saturation voltage enables <150 mW conduction loss per transistor at 0.7 A, critical for energy-sensitive portable devices. |
| hFE | 50–75 at IC = −2 A / VCE = −2 V: high DC current gain ensures reliable saturation with modest base drive, reducing MCU GPIO loading in discrete switch designs. |
| RCEsat | 250 mΩ max at IC = −1 A / IB = −50 mA: quantified on-resistance simplifies thermal modeling and PCB copper area calculation for thermal management. |
| Ptot | 700 mW per device on 4-layer FR4 with 1 cm² collector pad: total power dissipation limit defines maximum combined losses across both transistors under steady-state conditions. |
| fT | 100 MHz at VCE = −10 V / IC = −500 mA: transition frequency confirms suitability for medium-speed switching (e.g., PWM dimming up to ~100 kHz) without excessive delay. |
Pinout & Package
DFN2020D-6 (SOT1118D) is a 2.0 mm × 2.0 mm × 0.65 mm leadless, thermally enhanced plastic package with side-wettable flanks for automated optical inspection (AOI) and improved solder joint reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E1 | Emitter of transistor TR1: primary current return path for first PNP switch; connected to system ground or low-side reference in high-side switch configurations. |
| 2 | B1 | Base of transistor TR1: control input requiring negative bias relative to E1 to turn on TR1; driven by MCU GPIO or level-shifted logic. |
| 3 | C2 | Collector of transistor TR2: high-current output node for second PNP switch; routed to load (e.g., motor winding or LED string anode). |
| 4 | E2 | Emitter of transistor TR2: return path for TR2; may be tied to common rail or independently biased depending on dual-switch topology. |
| 5 | B2 | Base of transistor TR2: independent control input for TR2; enables asynchronous or complementary switching of both transistors. |
| 6 | C1 | Collector of transistor TR1: main power output for TR1; used for primary load switching or current sensing via external shunt. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | −300 mV typical at IC = −0.7 A reduces conduction loss by >40% vs. standard PNP transistors, extending battery life in portable chargers. |
| Exposed thermal pad | Integrated bottom-side thermal pad in DFN2020D-6 enables ≤131 K/W Rth(j-a) on 4-layer PCB with 1 cm² collector pad, allowing 700 mW total dissipation without heatsink. |
| Side-wettable flanks | Solderable side pads support automated optical inspection (AOI) of solder joints, improving manufacturing yield and field-reliability in high-volume consumer electronics. |
| High hFE at full load | hFE ≥50 at IC = −2 A ensures robust saturation with ≤200 mA base drive, eliminating need for Darlington stages or base resistors in compact layouts. |
| Bi-directional thermal symmetry | Matched thermal resistance profiles for both transistors enable balanced power sharing in dual-load or H-bridge half-bridge configurations. |
Applications
| Battery Load Switch | LED Constant-Current Driver |

IC Role / Device Role / Timing Role: Dual PNP switch isolates battery from loads; TR1 controls main power rail, TR2 enables auxiliary bias sequencing. Use Value: −300 mV VCEsat limits voltage drop to <300 mV at 0.7 A, preserving >95% of battery voltage for downstream LDOs and minimizing self-heating. |
Use Scenario: Linear constant-current regulation for automotive interior LED strips powered from 12 V supply. IC Role / Device Role / Timing Role: TR1 acts as pass transistor with feedback-controlled base drive; TR2 provides thermal foldback protection via emitter-coupled sensing. Use Value: hFE = 75 at IC = −1 A enables precise 100 mA–1 A current setting with <1% drift over temperature, avoiding external op-amps. |
| USB-C Power Delivery Switch | Fan/Motor Speed Control |
|
Use Scenario: Bidirectional 5–20 V power path switching in USB-C port controllers handling sink/source role negotiation. IC Role / Device Role / Timing Role: TR1 and TR2 operate in complementary mode to route power between CC logic and VBUS lines with reverse-polarity protection. Use Value: −55 V VCEO withstands 20 V PD transient surges; side-wettable flanks ensure AOI-verified solder integrity for safety-critical power routing. |
Use Scenario: PWM-controlled 12 V DC fan driver in industrial gateway enclosures with ambient temperatures up to 75 °C. IC Role / Device Role / Timing Role: TR1 handles main PWM switching; TR2 drives gate of external N-channel MOSFET for high-side boost, forming hybrid driver stage. Use Value: RCEsat = 250 mΩ at IC = −1 A keeps junction temperature rise <45 K on 4-layer PCB, eliminating thermal throttling at 100% duty cycle. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3020LSDQ | −30 V VCEO, −2.2 A IC, −220 mV VCEsat (lower voltage rating, lower VCEsat) | Optimized for 3.3–5 V systems only; unsuitable for 12–24 V battery management or LED drivers. | Select when operating below 30 V and prioritizing lowest possible saturation loss over voltage headroom. |
| BC847BDW1T1G | −45 V VCEO, −100 mA IC, −650 mV VCEsat (lower current, higher VCEsat, same package) | Rated for signal-level switching only; cannot sustain 2 A loads or deliver comparable thermal performance. | Choose only for low-power bias networks or logic-level translation where 2 A capability is unnecessary. |
Compared with DMTC3020LSDQ and BC847BDW1T1G, PBSS5255PAPSX uniquely balances −55 V blocking, −2 A current, and −300 mV VCEsat in a 2 mm × 2 mm footprint - making it the sole option for compact, high-efficiency 12–24 V dual-switch designs requiring AOI compatibility and thermal headroom.

FAQ
What is the maximum allowable junction temperature for PBSS5255PAPSX?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation above this temperature risks permanent degradation of hFE and increased leakage. Derating is required above 25 °C ambient - for example, total power must be reduced to ≤510 mW on standard FR4 at 75 °C ambient.
Can PBSS5255PAPSX be used in automotive applications?
No - PBSS5255PAPSX is explicitly non-automotive qualified per the revision history (v.2, April 2023), which states "Product changed to non-automotive qualification." It lacks AEC-Q101 stress testing and automotive-grade process controls; use only in industrial, consumer, or commercial equipment.
How does the DFN2020D-6 package support automated optical inspection (AOI)?
The package features side-wettable flanks (SWF): solderable metal sidewalls on all six terminals that reflect light uniformly during AOI. This enables high-confidence detection of solder bridging, insufficient fill, and misalignment - unlike conventional DFN packages with hidden solder joints.
What is the recommended PCB layout for optimal thermal performance?
For best thermal performance, use a 4-layer FR4 board with ≥1 cm² exposed copper pad connected to pins 3 (C2) and 6 (C1) via multiple thermal vias to internal ground/power planes. The datasheet specifies 131 K/W Rth(j-a) under these conditions - 35% lower than single-layer board performance.
