Product details

Overview

PBSS5330PA,115 from Nexperia is a PNP low V_CEsat Breakthrough In Small Signal (BISS) transistor in a DFN2020-3 (SOT1061) leadless package, rated for −30 V V_CEO, −3 A I_C, and 75 mΩ R_CEsat at −3 A/−300 mA drive. It serves as a high-efficiency load switch in battery-powered power management circuits with minimal board space and thermal resistance.

For engineers reviewing the PBSS5330PA,115 datasheet, PBSS5330PA,115 pinout, PBSS5330PA,115 application, or PBSS5330PA,115 equivalent, key selection criteria include its ultra-low saturation resistance, exposed collector pad for thermal dissipation, SOT1061 footprint compatibility, and PNP switching performance under pulsed DC loads up to 5 A peak.

Technical Context

This BISS transistor uses a proprietary silicon structure optimized for low V_CEsat while maintaining high current gain (h_FE = 100–160 at −3 A) and fast switching (t_on = 70 ns, t_off = 200 ns). Its base-emitter turn-on voltage is −0.75 V to −1.0 V at −1 A, enabling direct drive from 1.8–3.3 V logic with appropriate base current limiting.

The device features an exposed collector terminal acting as both electrical connection and thermal path, delivering R_th(j-a) as low as 60 K/W on ceramic PCB and 100 K/W on FR4 with 6 cm² copper pad. It operates across −55 °C to +150 °C junction temperature with guaranteed safe operation up to −30 V V_CBO and −6 V V_EBO.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−30 V - Maximum allowable collector-emitter voltage with open base; defines safe blocking capability in high-side switch configurations.
I_C	−3 A - Continuous DC collector current rating; supports sustained load switching in portable power rails and motor drivers.
R_CEsat	75 mΩ (typ) - Low saturation resistance at −3 A/−300 mA drive; reduces conduction loss to <100 mW and enables compact thermal design.
h_FE	100–160 - DC current gain at −3 A; ensures reliable saturation with modest base drive, reducing gate driver complexity.
t_off	200 ns - Turn-off time under −9 V V_CC, −2 A I_C, ±0.1 A base drive; supports PWM switching up to ~500 kHz without excessive switching loss.
R_th(j-a)	60 K/W - Junction-to-ambient thermal resistance on ceramic PCB; enables >2 W continuous dissipation without active cooling.
V_BEsat	−0.97 V (typ) - Base-emitter saturation voltage at −3 A/−300 mA; determines minimum required base drive voltage headroom.

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
PMMBT5401,115	Higher V_CEsat (−400 mV typ at −100 mA), lower I_C (−600 mA), TO-236 package	Not suitable for >1 A continuous loads; lacks exposed thermal pad	Select only for low-current signal switching where thermal performance is secondary.
PBSS5240PA,115	Same SOT1061 package, but −40 V V_CEO, −4 A I_C, higher R_CEsat (90 mΩ typ)	Offers higher voltage margin and current headroom at cost of 20% higher conduction loss	Prefer when system rail exceeds 24 V or peak load exceeds 3.5 A.

Compared with PBSS5330PA,115, PMMBT5401,115 trades thermal efficiency and current capacity for legacy package compatibility, while PBSS5240PA,115 extends voltage and current ratings at the expense of saturation resistance-making PBSS5330PA,115 optimal for 3–5 V, ≤3 A battery-switching applications demanding minimal board area and thermal overhead.

FAQ

What is the maximum continuous power dissipation for PBSS5330PA,115 on a standard FR4 PCB?

On a standard FR4 PCB with single-sided copper and tin-plated finish, PBSS5330PA,115 has a P_tot rating of 500 mW at T_amb ≤ 25 °C. Derating begins linearly above 25 °C, reaching zero dissipation at 75 °C ambient, per Figure 1 condition (1). This reflects its thermal resistance of 250 K/W in that mounting configuration.

Can PBSS5330PA,115 be used as a direct replacement for an NPN transistor in a high-side switch?

No-it is a PNP transistor and functions as a high-side switch by default, whereas NPN transistors require external level-shifting or complementary driver circuitry for high-side use. Substituting it for an NPN would invert logic polarity and may cause incorrect biasing; the NPN complement is PBSS4330PA, not PBSS5330PA,115.

What is the recommended PCB footprint for reflow soldering PBSS5330PA,115?

The official reflow footprint (Figure 17) specifies a 2.1 mm × 1.3 mm solder land for the exposed collector pad, two 0.5 mm × 0.5 mm pads for pins 1 (base) and 2 (emitter), and 0.25 mm solder mask clearance. The total occupied area is 2.3 mm × 1.7 mm, with 0.4 mm solder paste stencil aperture for the central thermal pad.

Does PBSS5330PA,115 meet automotive qualification standards?

No-PBSS5330PA,115 is not automotive-qualified. The datasheet explicitly states in Section 15.4 that "Unless this data sheet expressly states that this specific Nexperia product is automotive qualified, the product is not suitable for automotive use." It is rated for industrial and consumer applications only.
