Product details

Overview

PBSS5240Y,115 from NXP Semiconductors is a PNP low V_CE(sat) transistor in SOT363 (SC-88) package, rated for −40 V V_CEO, −2 A DC collector current, and <200 mΩ equivalent on-resistance. It delivers −100 mV V_CE(sat) at −100 mA/−1 mA drive and supports heavy-duty battery-powered motor and lamp drivers.

For engineers reviewing the PBSS5240Y,115 datasheet, PBSS5240Y,115 pinout, PBSS5240Y,115 application, or PBSS5240Y,115 equivalent, key selection criteria include verified low saturation voltage under high-current switching, thermal resistance of 463 K/W (standard PCB), and confirmed 6-pin SOT363 terminal mapping with dual-collector configuration.

Technical Context

This PNP transistor uses epitaxial planar technology optimized for low-saturation operation in high-current switching paths. Its dual-collector (pins 1,2,5,6) and shared emitter (pin 4) topology enables parallel current handling while maintaining compact footprint and thermal efficiency.

The device achieves −100 mV V_CE(sat) at IC = −100 mA/IB = −1 mA and maintains −350 mV up to −2 A with −200 mA base drive. Its 100 MHz f_T and 40 pF C_c support stable performance in DC/DC converter control and strobe flash timing circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−40 V - supports 36 V nominal battery systems with 10 % margin
I_C (DC)	−2 A - enables direct driving of medium-power lamps and small DC motors
V_CE(sat)	−100 mV @ −100 mA/−1 mA - reduces conduction loss by >70 % vs. standard PNP transistors
R_CE(sat)	<200 mΩ - simplifies thermal design in supply-line switching applications
f_T	100 MHz - ensures stable gain in high-frequency PWM-controlled DC/DC feedback paths
h_FE	300 @ −100 mA - provides sufficient current gain for logic-level base drive without external amplification

Pinout & Package

SOT363 (SC-88) plastic surface-mount package: 2.2 mm × 1.8 mm × 1.15 mm body, 0.65 mm pitch, 6 leads, standard footprint with 1 cm² collector pad option for enhanced thermal dissipation (P_tot = 430 mW).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6	Collector	Four electrically connected collector terminals - enable high-current routing and improved thermal spreading across PCB copper
3	Base	Single control input - accepts TTL/CMOS-compatible drive with −300 mA peak rating
4	Emitter	Common emitter node - referenced to system ground or negative rail in high-side switch configurations

Key Features

Feature	Design Value
Low V_CE(sat)	−100 mV at −100 mA enables <100 mW conduction loss in 1 A load switches
Dual-collector architecture	Four bonded collector pins reduce current density and improve reliability in motor driver H-bridge legs
High h_FE at high current	h_FE = 100 @ −2 A allows direct microcontroller GPIO drive without base resistors exceeding 1 kΩ
Thermal robustness	R_{th j-a} = 291 K/W with 1 cm² pad supports continuous −1.5 A operation at 70 °C ambient

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMT3005LKQ-7	−30 V V_CEO, −1.5 A I_C, −120 mV V_CE(sat) @ −500 mA - lower voltage rating, tighter saturation spec	Optimized for 12–24 V automotive body electronics; not suitable for 36 V battery systems	Select when operating voltage ≤28 V and sub-120 mV saturation is critical
BC807-40,115	−45 V V_CEO, −500 mA I_C, −300 mV V_CE(sat) @ −100 mA - higher voltage margin but 3× higher saturation voltage	Used in general-purpose logic-level switching where current <500 mA and thermal budget allows	Select only for low-power signal switching; avoid in motor or flash applications requiring <200 mV V_CE(sat)

Compared with DMT3005LKQ-7 and BC807-40,115, PBSS5240Y,115 uniquely balances −40 V rating, −2 A capability, and <200 mΩ R_CE(sat), making it the only option qualified for 36 V battery-powered equipment demanding both voltage headroom and high-efficiency conduction.

FAQ

What is the maximum continuous collector current for PBSS5240Y,115 under standard PCB conditions?

The maximum continuous DC collector current is −2 A, specified at T_amb ≤ 25 °C with single-side copper PCB and standard footprint. At 70 °C ambient, derating applies per R_{th j-a} = 463 K/W, limiting usable I_C to approximately −1.3 A for safe junction temperature operation.

Can PBSS5240Y,115 be used as a direct replacement for SOT223 PNP transistors in existing designs?

Yes - PBSS5240Y,115 is positioned as a performance upgrade for SOT223/SOT89 PNP transistors, offering lower V_CE(sat), higher current capability, and reduced thermal resistance in a smaller SOT363 footprint. Layout adaptation is required due to different pin count and pad geometry.

What is the base-emitter saturation voltage at full rated current?

V_BE(sat) is −1.1 V at I_C = −2 A and I_B = −200 mA, measured per datasheet conditions. This value reflects the forward-biased base-emitter junction under hard saturation, critical for calculating base drive power and verifying GPIO compatibility.

Does PBSS5240Y,115 have an NPN complement in the same package?

Yes - the NPN complement is PBSS4240Y, which shares identical SOT363 packaging, voltage/current ratings, and low V_CE(sat) performance. Both devices are designed for matched pair use in push-pull and H-bridge configurations requiring symmetrical switching characteristics.
