Product details

Overview

PBSS5480X,135 from Nexperia is a PNP low V_CEsat (BISS) transistor in SOT89 package, rated for −80 V V_CEO, −4 A continuous collector current, and 75 mΩ equivalent on-resistance. It serves as a medium-power switching device in DC-DC converters, motor drivers, and strobe flash circuits where low conduction loss and thermal efficiency are critical.

For engineers reviewing the PBSS5480X,135 datasheet, PBSS5480X,135 pinout, PBSS5480X,135 application, or PBSS5480X,135 equivalent, key selection criteria include verified V_CEsat ≤ 340 mV at −4 A/−200 mA drive, h_FE ≥ 80 at high current, thermal resistance R_th(j-s) = 16 K/W, and SOT89 collector-pad thermal design compatibility.

Technical Context

This BISS (Bipolar Integrated Schottky) transistor integrates a Schottky-clamped PNP structure to suppress saturation delay and reduce V_CEsat without compromising breakdown voltage. Its −80 V V_CEO and −10 A I_CM support robust operation in inductive load switching with flyback energy management.

Designed for surface-mount thermal performance, it features a dedicated collector pad optimized for 1–6 cm² copper mounting areas, enabling P_tot up to 2.5 W at T_amb ≤ 25 °C with 6 cm² FR4 layout. The 125 MHz f_T supports fast turn-off in PWM-driven applications like TFT inverters and LAN power switches.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−80 V: Maximum safe collector-emitter blocking voltage in open-base configuration, enabling use in 48 V industrial bus and 60 V automotive subsystems.
I_C (DC)	−4 A: Continuous collector current rating at T_amb = 25 °C with 6 cm² copper pad, sufficient for fan/motor drivers and battery charger switches.
V_CEsat	−220 to −340 mV at −4 A/−200 mA: Ultra-low saturation voltage reduces conduction loss and self-heating in high-duty-cycle switching.
R_CEsat	75 mΩ max: Equivalent on-resistance directly determines I²R loss in linear-mode or quasi-saturated operation.
h_FE	80–150 at −4 A: Sustained DC current gain ensures reliable base drive margin without excessive IB overhead in power control stages.
f_T	100–125 MHz: Transition frequency supports clean turn-off in PWM frequencies up to ~5 MHz with minimal storage time.
R_th(j-s)	16 K/W: Junction-to-solder-point thermal resistance enables direct thermal coupling to PCB ground plane for stable T_j < 150 °C.

Pinout & Package

SOT89 (SC-62) plastic surface-mounted package with exposed collector pad for enhanced thermal dissipation; 3-terminal configuration optimized for medium-power switching layouts.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current exit node; connected to system ground or low-side return path in high-side switch configurations.
2	Collector	Main power output terminal; electrically and thermally tied to large copper area for heat spreading and current handling.
3	Base	Control input; requires −200 mA drive for full −4 A conduction, compatible with standard logic-level or microcontroller GPIO via series resistor.

Key Features

Feature	Design Value
Low V_CEsat architecture	BISS structure achieves ≤ 340 mV at −4 A, cutting conduction loss by >40% vs. standard PNP transistors.
High-current h_FE	Minimum 80 at −4 A ensures stable switching with modest base drive, reducing driver IC cost and board space.
Thermally optimized SOT89	Exposed collector pad and 16 K/W R_th(j-s) allow 2.5 W dissipation on standard FR4-no heatsink required below 2 A avg.
Robust pulsed capability	−10 A I_CM (tp ≤ 1 ms) supports surge currents in motor startup and camera flash discharge events.
Wide temperature range	Specified from −65 °C to +150 °C junction, supporting industrial and automotive under-hood environments.

Applications

Fan & Motor Drivers

Strobe Flash Units

Use Scenario: Driving 12–24 V DC cooling fans or small PMDC motors in networking equipment and industrial controllers.

IC Role / Device Role / Timing Role: High-side PNP switch controlling motor current path with fast turn-on/turn-off governed by base drive timing.

Use Value: Low V_CEsat minimizes voltage drop and heat generation during continuous 2–4 A operation, extending fan life and simplifying thermal design.

Use Scenario: Discharging high-voltage capacitor banks into xenon or LED flash arrays in digital cameras and smartphones.

IC Role / Device Role / Timing Role: Primary discharge switch triggered by microcontroller pulse; must handle short-duration −5 A peaks.

Use Value: −10 A I_CM and 125 MHz f_T enable clean, jitter-free flash triggering with sub-microsecond response and minimal tail current.

TFT Display Inverters

LAN/ADSL Power Switches

Use Scenario: Generating high-voltage AC waveforms for LCD backlight inverters in portable displays and monitors.

IC Role / Device Role / Timing Role: Half-bridge high-side switch in resonant inverter topology; commutated at 50–200 kHz.

Use Value: Low storage time and 125 MHz f_T reduce switching losses and EMI during high-frequency hard-switching operation.

Use Scenario: Enabling/disabling phantom power or auxiliary supply rails in Ethernet PHY and DSL line interface units.

IC Role / Device Role / Timing Role: Controlled power gate between PoE injector and downstream PHY; switched at system boot or fault recovery.

Use Value: −80 V V_CEO safely isolates 57 V PoE voltage; low R_CEsat prevents voltage droop across the switch under 300–500 mA load.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP medium-power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
PBSS5380X,115	Same SOT89 package but −60 V V_CEO and −3 A I_C; V_CEsat slightly higher (≤ 400 mV @ −3 A).	Lower voltage/current rating limits use to ≤ 36 V systems and < 3 A loads.	Select when lower cost and reduced voltage margin are acceptable in consumer-grade power rails.
MMBT5401LT1G	SOT23 package, −60 V V_CEO, −0.6 A I_C, no collector pad; R_CEsat > 1 Ω at rated current.	Not suitable for > 1 A continuous switching; lacks thermal capacity for sustained power dissipation.	Only appropriate for signal-level or low-current biasing-not a functional replacement for PBSS5480X,135's power role.

Compared with PBSS5380X,115, PBSS5480X,135 delivers 33% higher voltage margin and 33% higher current capacity with superior thermal performance; versus MMBT5401LT1G, it provides 6.7× higher current rating and integrated thermal pad-making it the only viable option for medium-power discrete switching.

FAQ

Is PBSS5480X,135 pin-compatible with its NPN complement PBSS4480X?

Yes-PBSS5480X,135 (PNP) and PBSS4480X (NPN) share identical SOT89 package dimensions and pinout: Pin 1 = emitter, Pin 2 = collector, Pin 3 = base. This allows symmetrical layout in complementary switch designs such as H-bridges or push-pull drivers without footprint redesign.

What is the maximum allowable PCB copper area for optimal thermal performance?

The datasheet specifies three mounting conditions: standard footprint (0.55 W), 1 cm² collector pad (1 W), and 6 cm² collector pad (2.5 W). For full 2.5 W dissipation, use ≥ 6 cm² single-sided tin-plated copper on FR4, centered under Pin 2 (collector), per Figure 16 in the original datasheet.

Can PBSS5480X,135 be used in avalanche mode?

No-PBSS5480X,135 is not rated for repetitive avalanche operation. Its absolute maximum V_CEO of −80 V applies only under clamped inductive switching with external snubbers or freewheeling diodes; unclamped inductive turn-off may exceed this limit and cause failure.

Does the marking code *1Z indicate country of origin or date code?

The marking "*1Z" follows Nexperia's legacy NXP coding: * denotes manufacturing location (p = Hong Kong, t = Malaysia, W = China), and "1Z" is a date/batch code per internal lot traceability-full decoding requires Nexperia's material traceability system and is not publicly standardized.
