Product details

Overview

PBSS4360ZX from Nexperia is an NPN low V_CE(sat) BISS transistor in SOT223 (SC-73) package, designed for high-efficiency switching in medium-power applications. It delivers 60 V V_CEO, 3 A continuous I_C, 140 mΩ R_CE(sat) at 2 A/200 mA drive, and AEC-Q101 qualification - enabling use in automotive-grade DC-DC converters and LED backlight drivers.

For engineers reviewing the PBSS4360ZX datasheet, PBSS4360ZX pinout, PBSS4360ZX application, or PBSS4360ZX equivalent, key selection criteria include its low saturation resistance, thermal performance on FR4 PCBs with extended collector pad, peak current capability up to 6 A, and suitability for inductive load switching with fast turn-on and minimal conduction loss.

Technical Context

This BISS (Breakthrough In Small Signal) transistor employs optimized epitaxial base design and emitter geometry to achieve ultra-low V_CE(sat) while maintaining robust SOA and high h_FE (75 min at 3 A). Its dual-collector-pin configuration (Pins 2 & 4) enhances thermal dissipation and current handling in surface-mount layouts.

The device operates with V_BE(sat) ≤ 400 mV at I_C/I_B = 10, supports pulsed I_C up to 6 A (tp ≤ 1 ms), and exhibits f_T = 75–145 MHz - confirming suitability for medium-frequency switching control rather than RF amplification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - Maximum safe blocking voltage across collector-emitter with base open; defines upper rail limit in 48 V automotive supply switching.
I_C	3 A continuous - Sustained DC current rating under T_amb = 25 °C with standard SOT223 footprint; enables direct replacement of legacy TO-220 transistors in space-constrained designs.
R_CE(sat)	140 mΩ at I_C = 2 A, I_B = 200 mA - Low on-resistance reduces power loss to <140 mW at 2 A, minimizing heatsink requirements in battery-powered systems.
h_FE	75 min at I_C = 3 A - High DC current gain ensures reliable saturation with modest base drive (e.g., 300 mA IB for 3 A IC), easing MCU GPIO interface.
P_tot	1.35 W with 6 cm² collector pad - Thermal derating allows >1 W dissipation on standard FR4 PCBs, supporting sustained operation in ambient up to 75 °C.
f_T	75–145 MHz - Transition frequency confirms stable operation in PWM frequencies up to ~5 MHz, suitable for synchronous buck controller output stages.

Pinout & Package

SOT223 (SC-73) plastic surface-mounted package with 4 leads, featuring an enlarged copper collector pad for enhanced thermal transfer. Pin 1 = Base, Pins 2 & 4 = Collector (internally connected), Pin 3 = Emitter.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input requiring ~300 mA drive for full saturation at 3 A; low V_BE(sat) (<400 mV) eases logic-level interfacing.
2 & 4	Collector	Dual-terminal collector connection improves current sharing and thermal spreading; both pins must be soldered to PCB copper pour for rated P_tot.
3	Emitter	Power return path; tied to system ground or low-side switch node; requires low-inductance layout for fast switching stability.

Key Features

Feature	Design Value
Low V_CE(sat)	≤400 mV at 3 A/300 mA drive - cuts conduction loss by >50% vs. standard bipolar transistors, directly improving efficiency in 12–48 V DC-DC stages.
AEC-Q101 qualified	Stress-tested per automotive discrete semiconductor standard - validated for temperature cycling, HTRB, and ESD, enabling drop-in use in infotainment and body control modules.
High I_CM	6 A peak (1 ms pulse) - supports motor startup surges and relay coil energization without secondary protection, reducing BOM count.
Thermal resistance	R_th(j-sp) = 16 K/W - junction-to-solder-point metric confirms rapid heat extraction into PCB copper, critical for reliability in sealed enclosures.

Applications

DC-DC Converter Switch

Battery Charger Control

Use Scenario: Step-down regulation in 24 V to 5 V/3.3 V power rails for automotive ECUs and industrial sensors.

IC Role / Device Role / Timing Role: Low-side synchronous rectifier switch operating at 200–500 kHz PWM frequency.

IC Role / Device Role / Timing Role: Precision current-pass element modulated via DAC-driven base current.

Use Value: Tight h_FE tolerance (75–150 typ.) and low V_CE(sat) drift ensure ±2% current regulation across temperature.

LCD Backlight Driver

IC Role / Device Role / Timing Role: High-side or low-side constant-current switch driven by 3.3 V MCU GPIO with external base resistor.

Use Value: V_CE(sat) ≤ 275 mV at 2 A enables <550 mW loss per channel, permitting compact 4-layer PCB layout without thermal vias.

Use Scenario: Driving 12 V automotive relays (e.g., HVAC actuators) and piezoelectric buzzers in door modules and lighting controls.

IC Role / Device Role / Timing Role: Fast-switching load switch with integrated flyback diode requirement handled externally.

Use Value: 6 A I_CM withstands relay coil inrush (typically 3–5× steady-state), eliminating need for snubber networks in most cases.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN low-V_CE(sat) transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NSS40201MR6T1G	Lower V_CEO (40 V), higher R_CE(sat) (200 mΩ @ 2 A), same SOT223 package.	Restricted to ≤36 V systems; less efficient in 48 V DC-DC but lower cost for 24 V battery management.	Select when V_CEO margin is sufficient and thermal budget allows higher conduction loss.
Diodes Incorporated DXT60110PSQ-13	Higher V_CEO (100 V), similar R_CE(sat) (150 mΩ), AEC-Q101 qualified, same pinout.	Supports 72 V hybrid vehicle architectures; slightly higher V_BE(sat) increases base drive power.	Prefer for future-proofing in 48 V+ platforms where overvoltage transient immunity is critical.

Compared with NSS40201MR6T1G and DXT60110PSQ-13, PBSS4360ZX offers optimal balance of 60 V rating, 140 mΩ conduction resistance, and proven thermal performance on standard FR4 - making it ideal for cost-sensitive yet thermally demanding 12–48 V automotive subsystems.

FAQ

Is PBSS4360ZX pin-compatible with standard SOT223 NPN transistors?

Yes - PBSS4360ZX uses the standard SC-73 (SOT223) outline with Pin 1 = Base, Pins 2 & 4 = Collector, Pin 3 = Emitter. Its dual-collector configuration matches industry-standard SOT223 footprints, including those for MMBT4401 and ZTX653, though thermal pad layout should follow Nexperia's recommended 6 cm² copper area for full power rating.

What is the maximum allowable base current for continuous operation?

The absolute maximum DC base current is 500 mA per datasheet Table 5. For reliable long-term operation at 3 A collector current, Nexperia specifies 300 mA base drive (I_C/I_B = 10); exceeding 500 mA risks accelerated degradation of h_FE and increased V_BE(sat) drift over temperature.

Does PBSS4360ZX require an external flyback diode when driving inductive loads?

Yes - PBSS4360ZX is a bare transistor without integrated clamping. When switching relays, motors, or solenoids, a fast-recovery or Schottky diode (e.g., PMEG4010CPA) must be placed across the load to suppress inductive kickback and prevent V_CEO overshoot beyond 60 V.

How does thermal performance change with different PCB copper areas?

R_th(j-a) varies from 192 K/W (standard footprint) to 93 K/W (6 cm² collector pad), per Table 6. Using the full 6 cm² pad enables 1.35 W dissipation at T_amb = 75 °C, whereas the standard footprint limits continuous power to ~0.65 W - a 2× difference in usable output current before thermal shutdown.
