Product details

Overview

PBSS5350D,115 from Nexperia is a PNP low V_CEsat transistor in SOT457 (SC-74/TSOP6) package, rated for −50 V V_CEO, −3 A continuous I_C, and 120–150 mΩ R_CEsat; designed for high-efficiency supply-line switching and battery management where minimal conduction loss and compact PCB footprint are critical.

For engineers reviewing the PBSS5350D,115 datasheet, PBSS5350D,115 pinout, PBSS5350D,115 application, or PBSS5350D,115 equivalent, key selection criteria include verified PNP low-saturation performance at −2 A/−200 mA drive, thermal resistance under defined PCB mounting conditions, and compatibility with DC-DC converter topologies requiring robust current sinking capability.

Technical Context

This device operates as a discrete PNP bipolar junction transistor optimized for saturated switching-its low V_CEsat (≤300 mV at −2 A/−200 mA) and low R_CEsat (120–150 mΩ) reduce power dissipation and enable higher efficiency than standard transistors in load-switching roles.

It features a 6-pin SOT457 package with four collector terminals (pins 1,2,5,6), one base (pin 3), and one emitter (pin 4), enabling high-current handling and improved thermal spreading via multiple collector pads connected to PCB copper area.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−50 V - Maximum safe collector-emitter voltage with base open; defines maximum supply rail tolerance in high-side switch applications.
I_C (continuous)	−3 A - Continuous collector current rating; supports sustained load switching up to 3 A without derating under specified thermal conditions.
R_CEsat	120–150 mΩ - Measured collector-emitter saturation resistance at −2 A/−200 mA; directly determines conduction loss (P = I²R) in on-state operation.
V_CEsat	≤300 mV - Maximum collector-emitter saturation voltage at −2 A/−200 mA; enables <0.6 W conduction loss at full rated current.
h_FE	≥100 - Minimum DC current gain at −2 A/−200 mA; ensures reliable saturation with modest base drive current in digital control interfaces.
T_j max	150 °C - Maximum junction temperature; sets thermal design margin for PCB layout and heatsinking requirements.

Pinout & Package

Package: SOT457 (SC-74 / TSOP6), 6-lead surface-mount plastic package with exposed collector pads for enhanced thermal performance; dimensions per Figure 8 (1.9 mm × 2.7 mm × 0.95 mm).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6	Collector (C)	Four parallel collector terminals electrically connected internally; provide low-inductance, high-current paths and improved thermal coupling to PCB copper area.
3	Base (B)	Control terminal accepting −200 mA peak base current; requires compatible logic-level or driver-stage sourcing for full saturation.
4	Emiter (E)	Emitter output node; connects to system ground or return path in high-side switch configurations.

Key Features

Feature	Design Value
Low V_CEsat	≤300 mV at −2 A/−200 mA - Reduces on-state power loss by >50% vs. conventional PNP transistors, lowering thermal stress in space-constrained designs.
High current capability	−3 A continuous I_C - Supports direct control of moderate-power loads (e.g., LED banks, motor drivers, PMIC enable rails) without external current amplification.
Multi-collector package	4 collector pins in SOT457 - Enables lower effective thermal resistance (R_th(j-a) = 100 K/W on 4-layer PCB) and higher reliability under pulsed load conditions.
Small PCB footprint	2.7 mm × 1.9 mm outline - Saves >40% board area versus TO-236AB (SOT23) equivalents while maintaining higher current rating.

Applications

Supply Line Switching

Battery Management

Use Scenario: High-side power switch for USB-C PD port power delivery or system rail enable control.

IC Role / Device Role / Timing Role: PNP transistor configured as active-low controlled high-side switch, turning on/off 5–20 V supply rails.

Use Value: Low 120–150 mΩ R_CEsat limits voltage drop to <0.45 V at 3 A, preserving regulation margin and minimizing self-heating during sustained operation.

Use Scenario: Cell-balancing or protection FET in 2–4 cell Li-ion battery packs.

IC Role / Device Role / Timing Role: Discrete PNP switch controlling charge/discharge path or isolation between battery sections.

Use Value: −50 V V_CEO rating safely accommodates stacked-cell voltages up to 16.8 V with margin; −6 V V_EBO prevents unintended turn-on from leakage currents.

DC-to-DC Conversion

Industrial Load Control

Use Scenario: Synchronous rectifier or auxiliary switch in buck/boost converter secondary side.

IC Role / Device Role / Timing Role: Low-loss PNP switch replacing Schottky diode in non-synchronous topologies or assisting gate drive in hybrid configurations.

Use Value: ≤300 mV V_CEsat yields lower forward drop than typical 0.4–0.55 V Schottky diodes at 2 A, improving conversion efficiency by 0.8–1.2% at light-to-moderate loads.

Use Scenario: Solid-state relay replacement for PLC output modules or HVAC actuator control.

IC Role / Device Role / Timing Role: Discrete high-current switch driving solenoids, relays, or indicator LEDs in industrial control panels.

Use Value: −5 A I_CM peak rating handles inrush currents of inductive loads; 150 °C T_j max supports operation in unventilated enclosures up to 85 °C ambient.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP low-V_CEsat transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NSS5350F	Same SOT457 package, −50 V V_CEO, but higher R_CEsat (180–220 mΩ); h_FE min = 80 at −2 A.	Higher conduction loss at full load; suitable only where thermal headroom exceeds 15 °C or current is limited to ≤1.5 A.	Select when cost sensitivity outweighs efficiency targets and thermal constraints allow higher ΔT.
Diodes Inc. DXT53500	SOT457 package, −50 V V_CEO, −3 A I_C, but V_CEsat = 350 mV (typ) at −2 A; no multi-collector pinout.	Larger voltage drop reduces efficiency in high-duty-cycle switching; single collector limits thermal spreading capability.	Prefer only if existing PCB layout uses identical footprint and thermal design already accommodates +0.05 V drop.

Compared with NSS5350F and DXT53500, PBSS5350D,115 delivers the lowest verified R_CEsat (120–150 mΩ) and highest thermal performance due to its quad-collector structure-making it optimal for thermally constrained, high-efficiency PNP switching where <300 mV saturation voltage is mandatory.

FAQ

What is the maximum continuous collector current for PBSS5350D,115?

The PBSS5350D,115 is rated for −3 A continuous collector current (I_C) at T_amb ≤ 25 °C with appropriate PCB copper area (6 cm² for collector pad). Derating applies above 25 °C ambient, reaching zero current at 150 °C junction temperature per the absolute maximum ratings table.

Does PBSS5350D,115 have automotive qualification?

No. Per the 2023 revision history, PBSS5350D,115 is explicitly designated as non-automotive qualified. It is not tested or certified to AEC-Q101 standards. For automotive use, Nexperia offers the −Q qualified variant PBSS5350D,115-Q, which undergoes additional stress testing and lot traceability.

How many collector terminals does PBSS5350D,115 have, and why?

PBSS5350D,115 has four collector terminals (pins 1, 2, 5, and 6) in its SOT457 package. This multi-terminal configuration lowers effective bond wire inductance and improves thermal conduction from the die to the PCB, reducing R_th(j-a) to 100 K/W on a 4-layer board and supporting higher pulsed current capability.

Can PBSS5350D,115 replace an NPN transistor in a circuit?

No-it is a PNP transistor and cannot functionally substitute for an NPN without inverting the control logic and reconfiguring biasing. Its complementary NPN part is PBSS4350D (same package, voltage/current ratings, and low V_CEsat architecture), intended for symmetric design pairing in push-pull or H-bridge topologies.
