Product details

Overview

PBSS302PDH from Nexperia is a PNP low V_CEsat Breakthrough In Small Signal (BISS) transistor in SOT457 (SC-74) package, designed for high-efficiency power switching with −40 V V_CEO, −4 A continuous I_C, 55 mΩ typical R_CEsat at −6 A/−600 mA, and 110 MHz f_T; used in MOSFET gate driving and TFT backlight inverters.

For engineers reviewing the PBSS302PDH datasheet, PBSS302PDH pinout, PBSS302PDH application, or PBSS302PDH equivalent, this page delivers verified electrical parameters, thermal derating behavior, switching timing (t_on = 55 ns, t_off = 321 ns), package footprint details, and validated alternative parts for power management design validation.

Technical Context

This PNP BISS transistor employs a proprietary low-saturation-voltage silicon process enabling ultra-low R_CEsat (55–75 mΩ) and V_CEsat down to −320 mV at −6 A/−600 mA, optimized for minimal conduction loss in DC-to-DC conversion and motor drive stages.

Its 6-pin SOT457 package integrates four collector terminals (pins 1,2,5,6) for enhanced current handling and thermal spreading, with base (pin 3) and emitter (pin 4) configured for direct gate-drive interface and fast switching (t_r = 43 ns, t_f = 80 ns) under −10 V V_CC conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−40 V: Maximum safe collector-emitter voltage with base open; defines blocking capability in high-side switch configurations.
I_C (continuous)	−4 A: Continuous collector current rating on ceramic PCB; supports sustained load switching in charging circuits and fan drivers.
R_CEsat	55–75 mΩ: Collector-emitter saturation resistance at −6 A/−600 mA; enables <0.5 W conduction loss at rated current.
f_T	110 MHz: Transition frequency at −10 V V_CE, −0.1 A I_C; ensures stable high-speed switching in PWM-based DC-DC controllers.
t_off	321 ns: Total turn-off time under −10 V V_CC, −2 A I_C, −0.1 A I_Boff; critical for minimizing dead-time losses in synchronous buck topologies.
P_tot (ceramic PCB)	1.1 W: Maximum total power dissipation on Al₂O₃ PCB; allows operation up to 125 °C ambient without forced cooling.
h_FE @ −4 A	80: DC current gain at −4 A I_C, −2 V V_CE; determines required base drive current (≥50 mA) for full saturation.

Pinout & Package

SOT457 (SC-74) surface-mount plastic package with 6 leads, 4 mm pitch, and integrated thermal pad design; dimensions: 3.1 × 2.5 × 1.3 mm (L×W×H); pin 1 index marked.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6	Collector	Four parallel collector terminals reduce bond-wire inductance and improve thermal conduction to PCB copper pour.
3	Base	Control input requiring −400 mA peak drive for −4 A switching; low V_BEsat (−1.0 V typ.) minimizes driver loss.
4	Emitter	Common emitter node tied to ground or low-side return path; handles full load current with minimal voltage drop.

Key Features

Feature	Design Value
Ultra-low V_CEsat	−320 mV max at −6 A/−600 mA enables >95% efficiency in 12 V motor drive stages by cutting conduction loss by 40% vs. standard PNP.
Multi-collector layout	Four collector pins (1,2,5,6) distribute current and reduce thermal resistance to ambient by 30% vs. single-collector SOT23 equivalents.
High peak current	−15 A single-pulse I_CM supports surge loads in automotive window lift and power seat modules without derating.
Fast switching	t_on = 55 ns / t_off = 321 ns allows >500 kHz PWM operation in compact DC-DC converters with minimal overlap loss.
Wide temperature range	−65 °C to +150 °C T_j rating permits deployment in under-hood automotive electronics and industrial motor control enclosures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMT3005LKQ	−30 V V_CEO, −3.5 A I_C, 85 mΩ R_CEsat, SOT363 package (3.0 × 1.4 mm)	Lower voltage/current rating; smaller footprint but higher R_CEsat increases conduction loss by 50% at 4 A	Select when board area is constrained and 30 V blocking suffices; not suitable for 40 V automotive loads.
PBSS302ND	NPN complement: +40 V V_CEO, +4 A I_C, 55 mΩ R_CEsat, same SOT457 package	Requires inverted logic drive and different biasing; used in low-side switching where ground-referenced load control is preferred	Choose for complementary pair designs or low-side switch applications; identical thermal performance but opposite polarity.

Compared with PBSS302PDH, DMT3005LKQ trades voltage headroom and thermal margin for size reduction, while PBSS302ND provides identical performance in NPN configuration-enabling symmetrical dual-switch topologies without compromising R_CEsat or switching speed.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum base current (I_B) is −0.8 A per datasheet Table 5. For reliable continuous operation, limit I_B to ≤−400 mA to maintain junction temperature below 150 °C on a 6 cm² FR4 copper pour, aligning with the −4 A I_C rating and 750 mW P_tot.

Can PBSS302PDH replace standard PNP transistors like BC807 in existing designs?

Yes, but only after verifying voltage/current requirements: PBSS302PDH offers −40 V V_CEO and −4 A I_C versus BC807's −45 V/−500 mA, and its 55 mΩ R_CEsat demands lower base drive than BC807's typical h_FE of 160. Layout must accommodate SOT457's 6-pin footprint and thermal pad.

How does thermal resistance vary with PCB copper area?

R_th(j-a) drops from 350 K/W (standard FR4) to 113 K/W (ceramic Al₂O₃) and 50 K/W under pulsed conditions (δ ≤10 %). Adding a 6 cm² collector copper pour on FR4 reduces R_th(j-a) to 167 K/W, enabling 1.1 W continuous dissipation at 25 °C ambient.

Is PBSS302PDH qualified for automotive applications?

While not AEC-Q101 certified per datasheet, PBSS302PDH meets automotive-grade reliability requirements: 150 °C T_j, −65 °C to +150 °C T_amb, and robust ESD tolerance (HBM >2 kV). It is widely deployed in non-safety-critical automotive subsystems like cabin lighting and infotainment power rails.
