Product details
Overview
PBSS4160QAZ from Nexperia is an NPN low VCE(sat) transistor in a DFN1010D-3 (SOT1215) leadless package, designed for high-efficiency switching in space-constrained loadswitch and battery-powered applications. It delivers 60 V VCEO, 1 A continuous IC, 170–235 mΩ RCE(sat) at IC = 1 A / IB = 0.1 A, and operates up to 150 °C junction temperature - enabling compact, thermally efficient power switches in portable chargers and motor drivers.
For engineers reviewing the PBSS4160QAZ datasheet, PBSS4160QAZ pinout, PBSS4160QAZ application, or PBSS4160QAZ equivalent, key selection criteria include verified low saturation resistance under pulsed 1 A conditions, side-wettable flanks for automated optical inspection, thermal derating behavior on FR4 PCBs, and compatibility with 0.75 mm pitch layout constraints.
Technical Context
This NPN transistor employs a silicon planar epitaxial process optimized for minimal VCE(sat) and high hFE at high collector currents - achieving 85–130 DC current gain at IC = 1 A and 150 °C ambient. Its DFN1010D-3 package integrates solderable side pads and a thermally enhanced copper-exposed collector terminal to support 1000 mW dissipation on 4-layer FR4 with 1 cm² mounting pad.
Switching performance is characterized by 100 ns turn-on time and 670 ns turn-off time under standardized test conditions (VCC = 10 V, IC = 0.5 A, IBon/IBoff = ±25 mA), with fT of 120–180 MHz confirming suitability for medium-frequency switching control in DC-DC and load management circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Maximum safe collector-emitter voltage with base open; defines maximum supply rail compatibility in loadswitch designs. |
| IC | 1 A continuous - Rated DC collector current; supports sustained operation in battery protection and fan drive circuits. |
| RCE(sat) | 170–235 mΩ at IC = 1 A / IB = 0.1 A - Directly determines conduction loss and self-heating in high-current switching paths. |
| hFE | 85–130 at IC = 1 A - Ensures reliable saturation with modest base drive, reducing gate driver complexity in discrete switch stages. |
| toff | 670 ns - Enables PWM operation up to ~1.5 MHz without significant switching loss penalty in compact power modules. |
| Rth(j-a) | 125 K/W on 4-layer FR4 with 1 cm² collector pad - Quantifies thermal bottleneck for board-level cooling design and heatsink-less operation. |
Pinout & Package
Package: DFN1010D-3 (SOT1215), 1.1 mm × 1.0 mm × 0.37 mm body, leadless, with side-wettable flanks and exposed collector terminal for thermal and mechanical robustness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input requiring ~100 mA peak drive for full saturation; connected to MCU GPIO or logic-level driver output. |
| 2 | Emitter (E) | Reference node tied to system ground or low-side return path; forms common emitter configuration with collector as switched output. |
| 3 & 4 | Collector (C) | High-current switched output terminal; pins 3 and 4 are internally joined and electrically identical - both must be soldered to maximize thermal and current capacity. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RCE(sat) | 170–235 mΩ enables <170 mW conduction loss at 1 A, reducing thermal stress and eliminating need for heatsinks in handheld devices. |
| Solderable side pads | Visible flank metallization allows automated optical inspection (AOI) and improves solder joint reliability during reflow on fine-pitch PCBs. |
| Thermally enhanced DFN | Exposed collector pad and side-wettable flanks deliver 125 K/W Rth(j-a) on 4-layer boards - 2× better than standard SOT23 at same footprint. |
| High hFE at full load | Min. 85 gain at IC = 1 A reduces required base current to ≤12 mA, easing drive requirements from low-power microcontrollers. |
Applications
| Smartphone Battery Protection | USB-C Power Delivery Switch |
|---|---|
|
Use Scenario: Isolating main battery from USB-C port during hot-plug events to prevent backfeed and overvoltage damage. IC Role / Device Role / Timing Role: Low-side loadswitch controlling battery-to-port power path; activated within 100 ns of fault detection. Use Value: 170 mΩ RCE(sat) limits voltage drop to <170 mV at 1 A, preserving PD negotiation voltage margins and minimizing heat in sealed enclosures. |
Use Scenario: Enabling/disabling 20 V/5 A power path between USB-C source and device internal rails. IC Role / Device Role / Timing Role: Discrete NPN switch driven by PD controller GPIO; handles bidirectional current blocking and fast turn-off during fault.

| Wireless Earbud Charging Case | Small Fan Speed Control |
|

IC Role / Device Role / Timing Role: High-efficiency pass element in linear charger stage; biased in active region for precise current limiting. Use Value: 130 max hFE enables stable current regulation with simple op-amp feedback, avoiding oscillation seen with lower-gain transistors. |
Use Scenario: PWM-controlled 5 V DC fan in network router or set-top box with thermal throttling. IC Role / Device Role / Timing Role: Low-side switch modulating fan voltage; driven by 25 kHz MCU timer output.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low VCE(sat) NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS12201LT1G | Higher RCE(sat) (250–350 mΩ), same 60 V rating, SOT-23 package with higher Rth(j-a) (300+ K/W). | Limited to <500 mA continuous due to thermal constraints; unsuitable for 1 A battery switches. | Select only when board space permits larger SOT-23 and thermal budget allows >2× conduction loss. |
| Nexperia PBSS4140QAZ | Lower VCEO (40 V), identical package and RCE(sat) spec, but reduced voltage margin. | Acceptable in 12–24 V systems (e.g., automotive accessories), not for 48 V or USB PD 20 V+ rails. | Choose only if system max voltage is ≤40 V and cost reduction is prioritized over voltage headroom. |
Compared with NSS12201LT1G and PBSS4140QAZ, PBSS4160QAZ uniquely balances 60 V capability, 1 A rating, and sub-235 mΩ RCE(sat) in a 1.1 mm × 1.0 mm footprint - making it the sole option among the three for thermally constrained 1 A/60 V loadswitching where side-wettable flanks are required for AOI.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum DC base current (IB) is 0.3 A per datasheet limiting values. However, for reliable long-term operation at 1 A collector current, the recommended continuous IB is 100 mA - matching the test condition for RCE(sat) specification and ensuring stable hFE and thermal performance without degradation.
Can PBSS4160QAZ be used in a high-side switch configuration?
No - PBSS4160QAZ is an NPN transistor requiring base voltage ≥ emitter voltage + 0.7 V for turn-on. In high-side configurations, this demands a charge-pump or bootstrap gate driver, which defeats its low-VCE(sat) advantage. It is strictly intended for low-side switching where emitter is grounded.
How does the dual-collector pin (pins 3 and 4) affect PCB layout?
Pins 3 and 4 are internally shorted collector terminals and must be connected to the same copper pour. Both require full-solder coverage - splitting them across separate nets causes current imbalance, localized heating, and potential solder joint failure. The recommended land pattern uses a single 1.0 mm × 0.75 mm thermal pad bridging both pins.
Is PBSS4160QAZ qualified for automotive applications?
No - PBSS4160QAZ is not AEC-Q101 qualified. The datasheet explicitly states "Non-automotive qualified products" and excludes automotive use in legal disclaimers. For automotive loadswitching, Nexperia's PMXB series or similar AEC-Q101-certified alternatives must be selected instead.
