Product details

Overview

PBSS301PZ,135 from NXP Semiconductors is a PNP low V_CEsat Breakthrough In Small Signal (BISS) transistor in SOT223 (SC-73) package, designed for high-efficiency switching in power control circuits. It delivers −12 V V_CEO, −5.7 A continuous I_C, and ultra-low R_CEsat of 32.5 mΩ at I_C = −4 A / I_B = −200 mA, enabling compact DC-DC converters and MOSFET gate drivers.

For engineers reviewing the PBSS301PZ,135 datasheet, PBSS301PZ,135 pinout, PBSS301PZ,135 application, or PBSS301PZ,135 equivalent, this device is selected for high-current, low-saturation-voltage PNP switching where thermal efficiency, PCB area reduction, and fast turn-off (t_off = 325 ns) are critical in motor control and charging circuits.

Technical Context

This BISS transistor uses an optimized PNP epitaxial structure to achieve significantly lower V_CEsat and higher h_FE at high collector currents compared to standard small-signal transistors. Its dual-collector pin configuration (Pins 2 & 4) supports enhanced thermal dissipation on FR4 PCBs with extended copper pads.

It operates with V_EB up to −5 V and maintains stable h_FE from −0.5 A to −7 A (min 100 @ −7 A), supporting wide dynamic range in PWM-driven loads. Switching performance is characterized with t_d = 10 ns, t_r = 55 ns, and t_f = 160 ns under −12.5 V V_CC, −3 A I_C, and ±0.15 A base drive.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−12 V - Maximum safe collector-emitter voltage with open base; defines upper rail limit in high-side switch configurations
I_C	−5.7 A - Continuous DC collector current; enables direct driving of medium-power loads without external heatsinking on standard FR4
R_CEsat	32.5 mΩ (typ) - Low saturation resistance reduces conduction loss and self-heating in high-duty-cycle applications
h_FE	250–400 (at I_C = −0.5 A) - High DC current gain allows low base drive current, easing MCU GPIO or logic-level driver requirements
t_off	325 ns - Fast turn-off time supports high-frequency switching (>1 MHz) in synchronous rectifiers and Class-D drivers
P_tot	1.7 W (FR4 w/6 cm² collector pad) - Thermal capability enables >1 W sustained power handling without forced cooling
f_T	140 MHz - Transition frequency confirms suitability for RF-coupled pre-driver stages and broadband amplification

Pinout & Package

SOT223 (SC-73) plastic surface-mounted package with four leads and integrated heat sink; Pin 1 = Base, Pins 2 & 4 = Collector (electrically common), Pin 3 = Emitter.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input node requiring −285 mA base current for full saturation at I_C = −5.7 A (IC/IB ≈ 20)
2 & 4	Collector	Dual-terminal collector connection improves thermal spreading and current sharing; must be tied together externally
3	Emitter	Common emitter reference; connects to system ground or negative rail in high-side switch topologies

Key Features

Feature	Design Value
Low V_CEsat	−170 mV (typ) at I_C = −5.7 A / I_B = −285 mA - Reduces conduction loss by >50% vs. conventional PNP transistors
High I_C capability	−5.7 A continuous rating - Supports direct replacement of TO-220 devices in space-constrained designs
Thermal robustness	R_th(j-sp) = 15 K/W - Enables rapid heat transfer from junction to solder point, improving reliability under pulsed loads
PCB area reduction	4-lead SOT223 footprint occupies ~30% less board area than comparable SO-8 or DPAK packages
High h_FE at high I_C	150 (min) at I_C = −4 A - Maintains strong current amplification even near maximum rating, easing drive design

Applications

IC Role / Device Role / Timing Role: Active pull-down stage providing fast, low-impedance discharge path for MOSFET gate capacitance.

Use Value: 325 ns t_off ensures <50 ns dead-time margin at 500 kHz switching, preventing shoot-through in bridge topologies.

Use Value: Stable h_FE across temperature (±15% from −55 °C to 100 °C) enables accurate current mirroring without calibration.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMT3005LKQ	−30 V V_CEO, −5 A I_C, R_CEsat = 45 mΩ (typ); SOT-23 package	Lower voltage rating and smaller package limit use to ≤15 V systems with tighter space constraints	Select when board area is critical and voltage stress remains below 15 V; not suitable for 12 V bus with transients
BC807-40,115	−45 V V_CEO, −500 mA I_C, V_CEsat = −300 mV @ 100 mA; SOT-23	Rated for general-purpose switching only; insufficient current capacity for motor or charging loads	Use only for signal-level biasing or low-power logic interfacing-not a functional substitute for PBSS301PZ,135

Compared with DMT3005LKQ and BC807-40,115, PBSS301PZ,135 uniquely combines −12 V/−5.7 A rating, sub-200 mV V_CEsat, and SOT223 thermal performance-making it the only viable option for high-current, thermally constrained PNP switching in DC-DC and motor control.

FAQ

What is the maximum allowable base current for PBSS301PZ,135?

The absolute maximum peak base current is −400 mA per the datasheet limiting values table. For reliable continuous operation, I_B should not exceed −285 mA, which corresponds to the specified test condition for I_C = −5.7 A (IC/IB = 20). Exceeding this may cause localized heating at the base-emitter junction and degrade long-term h_FE stability.

Can PBSS301PZ,135 be used in linear regulator applications?

No-it is not optimized for linear operation. The device lacks guaranteed Safe Operating Area (SOA) curves beyond pulse conditions, and its R_CEsat-based design prioritizes saturated switching over analog gain linearity. Use only in switching modes (e.g., PWM, on/off control); linear regulation risks thermal runaway due to positive temperature coefficient of V_CEsat.

Is the SOT223 package lead-free and RoHS compliant?

Yes. Per NXP's product change notification PCN-2006-01 and the PBSS301PZ_2 datasheet revision history, the SOT223 package uses lead-free terminations and complies with EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) for reflow soldering.

How does the dual-collector pin configuration affect PCB layout?

Pins 2 and 4 are internally connected to the same collector region and must be shorted together on the PCB. This dual-pin arrangement increases copper area for heat spreading-designers should route both pins to a shared thermal pad ≥6 cm² on FR4 or use ceramic substrates to achieve the 1.7 W power rating. Isolating either pin degrades thermal performance and violates the specified mounting condition.
