Product details
Overview
PBSS304NZ-QF from Nexperia is an NPN low VCE(sat) Breakthrough In Small Signal (BISS) transistor in SOT223 (SC-73) package, designed for high-voltage switching roles where low conduction loss and thermal efficiency are critical. It delivers 60 V VCEO, 5.2 A continuous IC, 39–55 mΩ RCE(sat) at 4 A/200 mA drive, and operates up to 150 °C junction temperature - enabling compact, high-efficiency DC-DC converters and MOSFET gate drivers.
For engineers reviewing the PBSS304NZ-QF datasheet, PBSS304NZ-QF pinout, PBSS304NZ-QF application, or PBSS304NZ-QF equivalent, this page provides verified technical context, validated pin functions, real-world use cases in automotive and industrial power stages, and confirmed alternative parts with documented functional trade-offs.
Technical Context
This BISS transistor uses a proprietary epitaxial structure to achieve ultra-low saturation resistance while maintaining high current gain (hFE = 150–520 across 0.5–4 A) and fast switching (ton = 110 ns, toff = 555 ns). Its dual-collector pin configuration (Pins 2 & 4) enhances thermal dissipation on PCBs with extended copper pads.
It operates with base-emitter turn-on voltage of 0.75–0.85 V and VBE(sat) ≤ 1.05 V at 4 A/400 mA, supporting efficient drive from standard logic-level controllers. The device is qualified per AEC-Q101 for automotive applications and specified for operation from −65 °C to +150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Maximum blocking voltage in common-emitter configuration; enables use in 48 V and higher DC bus systems. |
| IC | 5.2 A continuous - Sustained collector current under FR4 PCB mounting with standard footprint; supports medium-power switching loads. |
| RCE(sat) | 39–55 mΩ at IC = 4 A, IB = 200 mA - Directly determines conduction loss (Ploss ≈ IC² × RCE(sat)) and thermal rise in high-duty-cycle operation. |
| hFE | 150–520 (IC = 0.5–4 A) - High DC current gain reduces required base drive current, easing interface with microcontrollers and gate drivers. |
| toff | 555 ns - Total turn-off time defines minimum achievable switching frequency and dead-time requirements in half-bridge topologies. |
| Tj(max) | 150 °C - Maximum junction temperature sets thermal design margin; requires Rth(j-a) ≤ 74 K/W for full 5.2 A operation on FR4 with 6 cm² collector pad. |
Pinout & Package
SOT223 (SC-73) plastic surface-mounted package with 4 leads and integrated heatsink capability; Pin 2 and Pin 4 are internally connected collectors, enabling dual-copper-pad thermal routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input terminal; accepts 50–400 mA base current to saturate transistor at target IC. |
| 2 | Collector | Main high-side current path terminal; electrically tied to Pin 4 for parallel current handling and enhanced thermal conduction. |
| 3 | Emiter | Reference node for emitter-follower or low-side switch configurations; connects to ground or load return path. |
| 4 | Collector | Second collector terminal; identical to Pin 2 - used for symmetric PCB layout and improved heat spreading across two copper areas. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | 155–220 mV at IC = 4 A/200 mA - Reduces power dissipation by >40% vs. standard bipolar transistors, lowering heatsink requirements. |
| High IC/ICM | 5.2 A continuous / 10.4 A peak - Supports pulsed motor control and inrush-current-tolerant power switches without derating. |
| High hFE at high IC | 250 (typ.) at IC = 2 A - Maintains strong current amplification under load, minimizing base drive circuit complexity and power loss. |
| Thermal resistance | Rth(j-sp) = 15 K/W - Low junction-to-solder-point resistance enables rapid heat transfer to PCB copper, critical for sustained high-current operation. |
Applications
| High-Voltage DC-DC Conversion | Automotive Motor Control |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN high-current low-saturation transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PHPT60603NX | 60 V VCEO, 6 A IC, but higher RCE(sat) (65 mΩ typ. at 4 A); SOT223-4 package with same pinout. | Lower efficiency in continuous conduction mode due to +15 mΩ RCE(sat); better suited for intermittent duty cycles. | Select when higher peak current margin is prioritized over thermal performance at full load. |
| MMBT3904-TP | 40 V VCEO, 200 mA IC, standard small-signal NPN; SOT23 package, not pin-compatible. | Not suitable for high-voltage/high-current roles; only viable for signal-level pre-driver stages. | Use only as base bias amplifier upstream of PBSS304NZ-QF - never as direct replacement. |
Compared with PHPT60603NX, PBSS304NZ-QF offers lower conduction loss and superior thermal capability on FR4; versus MMBT3904-TP, it delivers 26× higher current and 1.5× higher voltage rating - making it uniquely fit for primary power switching rather than signal conditioning.

FAQ
What is the maximum safe operating current for PBSS304NZ-QF on a standard FR4 PCB?
The absolute maximum continuous collector current is 5.2 A, but this assumes a 6 cm² copper pad on the collector terminals (Pins 2 & 4) and ambient temperature ≤25 °C. With standard footprint (no extended pad), derating to 3.5 A is recommended to maintain Tj ≤125 °C under continuous operation.
Can PBSS304NZ-QF be used in a high-side switch configuration?
Yes - its 60 V VCEO and low RCE(sat) make it suitable for high-side switching in 48 V systems. However, base drive must be referenced to the emitter (i.e., floating or bootstrapped), and VBE must remain within −5 V to +5 V to avoid damage to the emitter-base junction.
How does the dual-collector pin (Pins 2 & 4) affect PCB layout?
Pins 2 and 4 are internally shorted collectors, intended to be routed to separate large copper areas on the PCB to double thermal conduction paths. This reduces effective Rth(j-a) from 179 K/W (standard) to 74 K/W (6 cm² pad), directly improving power handling and reliability.
Is PBSS304NZ-QF compliant with automotive qualification standards?
Yes - it is qualified to AEC-Q101 for stress testing including HTGB, HTRB, and temperature cycling. The datasheet confirms operation from −65 °C to +150 °C and specifies parameters under automotive-relevant conditions such as Tj = 150 °C and pulse-tested ICM = 10.4 A.
