Product details
Overview
PBSS4360XX from Nexperia is an NPN low VCE(sat) BISS transistor in SOT89 package, rated for 60 V VCEO, 3 A continuous collector current, and 140 mΩ RCE(sat) at IC = 2 A / IB = 200 mA. It serves as a high-efficiency switching element in DC-DC converters and battery-powered load drivers where thermal performance and voltage headroom are critical.
For engineers reviewing the PBSS4360XX datasheet, PBSS4360XX pinout, PBSS4360XX application, or PBSS4360XX equivalent, key selection criteria include its AEC-Q101 qualification, 6 A peak pulse current capability, 1.35 W power dissipation on 6 cm² copper pad, and low saturation resistance enabling reduced conduction loss in 5–24 V supply rail switching.
Technical Context
This BISS (Breakthrough in Small Signal) transistor uses optimized epitaxial base design to achieve lower VCE(sat) than standard bipolar transistors while maintaining robust hFE of 75 at IC = 3 A. Its structure supports fast switching with fT = 145 MHz and low Cc = 11 pF, making it suitable for medium-frequency PWM control.
The device operates across −55 °C to 150 °C junction temperature, with thermal resistance Rth(j-a) as low as 93 K/W when mounted on 6 cm² copper, directly supporting automotive under-hood and industrial power module designs requiring sustained 2–3 A DC switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Maximum blocking voltage in common-emitter configuration; enables use in 48 V system rails and 24 V industrial supplies. |
| IC | 3 A continuous - Sustained collector current rating at Tamb ≤ 25 °C with adequate PCB copper; supports LED driver and relay coil loads. |
| RCE(sat) | 140 mΩ at IC = 2 A / IB = 200 mA - Low on-resistance reduces power loss to <280 mW under typical drive, minimizing heatsink requirements. |
| fT | 145 MHz - Transition frequency confirms suitability for PWM frequencies up to ~10 MHz with acceptable gain margin. |
| hFE | 75 at IC = 3 A - Sufficient DC current gain to support direct microcontroller GPIO drive (e.g., 3.3 V/20 mA source) without external pre-biasing. |
| Ptot | 1.35 W on 6 cm² copper - Thermal derating allows stable operation at full current in compact SMT layouts with enhanced thermal pads. |
Pinout & Package
SOT89 (SC-62) plastic surface-mount package: 4.5 mm × 2.5 mm × 1.5 mm body, 1.5 mm lead pitch, with exposed collector tab for thermal conduction. Mounting pad area directly impacts power handling-6 cm² copper yields 1.35 W rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (E) | Current return path; connected to ground or low-side reference; requires low-inductance trace for switching stability. |
| 2 | Collector (C) | Main power output terminal; electrically and thermally tied to large copper pour for heat dissipation and current routing. |
| 3 | Base (B) | Control input; driven by logic-level signal; requires series resistor (e.g., 1 kΩ) to limit IB ≤ 500 mA absolute max. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and body electronics per stress test requirements. |
| Low VCE(sat) | 275 mV at IC = 2 A / IB = 200 mA - Reduces conduction loss by >40% vs. standard bipolar transistors at same current. |
| High ICM | 6 A single-pulse (tp ≤ 1 ms) - Supports inrush current handling in motor and solenoid drive without secondary protection. |
| Thermal robustness | Rth(j-a) = 93 K/W with 6 cm² copper - Enables operation at full 3 A load in ambient up to 70 °C without forced air. |
Applications
| DC-DC Converter Switch | Battery Charger Control |
|---|---|
|

Use Scenario: Driving 24 V DC relays and buzzer coils in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Solid-state replacement for mechanical relay contacts in high-cycle-count switching applications. Use Value: 6 A ICM safely absorbs 5× inductive kickback energy; AEC-Q101 qualification guarantees reliability over 10⁶ cycles at 85 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low-saturation switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40301MR6T1G | VCEO = 40 V, IC = 3 A, RCE(sat) = 160 mΩ - Lower voltage rating, higher saturation resistance. | Restricted to ≤36 V systems; less efficient in 48 V DC-DC stages. | Select only if board space requires SOT-23 and voltage stress remains <30 V. |
| Diodes Incorporated DXT6011000000000 | VCEO = 60 V, IC = 2.5 A, RCE(sat) = 150 mΩ - Slightly lower current and higher RCE(sat). | Marginally lower thermal headroom in continuous 3 A loads; requires larger copper area for same Ptot. | Acceptable for intermittent duty-cycle applications but not for sustained 3 A linear regulation. |
Compared with NSS40301MR6T1G and DXT6011000000000, PBSS4360XX delivers superior voltage margin, lower conduction loss, and AEC-Q101 validation-making it the preferred choice for automotive-grade 48 V subsystems and industrial power switches demanding long-term reliability at full rated current.

FAQ
Is PBSS4360XX pin-compatible with standard SOT89 NPN transistors?
Yes-PBSS4360XX uses standard SOT89 pinning: Pin 1 = Emitter, Pin 2 = Collector, Pin 3 = Base. This matches industry-standard layout for SOT89-packaged NPN transistors, enabling drop-in replacement in existing footprints without PCB revision, provided thermal and electrical margins are verified.
What is the maximum safe base current for continuous operation?
The absolute maximum DC base current is 500 mA, but for reliable continuous operation, IB should be limited to ≤200 mA (per datasheet test condition for RCE(sat)). Exceeding this risks thermal runaway at high ambient temperatures; a 1 kΩ series resistor from a 3.3 V GPIO limits IB to 3.3 mA, sufficient for 3 A IC given hFE ≥ 75.
Can PBSS4360XX replace a MOSFET in low-side switching applications?
Yes, in cases where gate drive complexity, cost, or EMI sensitivity make MOSFETs impractical. PBSS4360XX offers comparable RDS(on)-equivalent conduction loss (140 mΩ), no gate charge, and inherent avalanche ruggedness-ideal for 1–10 kHz PWM in LED drivers and relay controls where sub-ns switching is unnecessary.
Does PBSS4360XX require a flyback diode when driving inductive loads?
Yes-although the device has robust SOA, inductive loads (relays, motors, solenoids) generate reverse EMF exceeding VCEO during turn-off. A fast-recovery flyback diode (e.g., BAS21) must be placed across the load to clamp voltage spikes and prevent junction breakdown, especially in 24–48 V systems.
