Product details

Overview

PBSS304PZ,135 from Nexperia is a PNP low V_CEsat Breakthrough In Small Signal (BISS) transistor in SOT223 (SC-73) package, designed for high-voltage switching roles in power stages. It delivers −60 V V_CEO, −4.5 A continuous I_C, and ultra-low 53–75 mΩ R_CEsat at −4 A/−200 mA drive-enabling efficient high-side switching in DC-DC converters and motor drivers.

For engineers reviewing the PBSS304PZ,135 datasheet, PBSS304PZ,135 pinout, PBSS304PZ,135 application, or PBSS304PZ,135 equivalent, key selection criteria include verified V_CEsat performance at high current, thermal resistance under FR4 PCB mounting, collector-emitter saturation resistance consistency, and compatibility with high-voltage gate driving topologies.

Technical Context

This BISS transistor uses a proprietary epitaxial base structure to achieve high h_FE (120–295) across −0.5 A to −4.5 A I_C, enabling stable current gain even under heavy conduction. Its low R_CEsat stems from reduced base spreading resistance and optimized emitter geometry-not standard bipolar architecture.

It operates as a high-efficiency PNP switch in complementary configurations (e.g., with NPN PBSS304NZ), supporting fast switching (t_on = 80 ns, t_off = 320 ns) while maintaining robust safe operating area up to −9 A peak I_CM and 150 °C T_j.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V: Maximum blocking voltage between collector and emitter with base open-supports 48 V and 60 V bus applications.
I_C	−4.5 A continuous: Rated DC collector current under standard FR4 PCB mounting-sufficient for medium-power load switching.
R_CEsat	53–75 mΩ at I_C = −4 A, I_B = −200 mA: Low on-resistance enables <0.3 W conduction loss at full rated current.
h_FE	120–295 at V_CE = −2 V: High DC current gain across wide I_C range reduces required base drive current.
t_off	320 ns: Total turn-off time defines maximum practical switching frequency in hard-switched topologies.
T_j max	150 °C: Maximum junction temperature-sets thermal design margin for ambient and PCB layout constraints.
P_tot	1.7 W on FR4 with 6 cm² collector pad: Realistic power dissipation limit for thermally enhanced PCB layouts.

Pinout & Package

The PBSS304PZ,135 is housed in a SOT223 (SC-73) plastic surface-mounted package with four leads and an integrated heatsink pad on pins 2 and 4 (collector). The package supports reflow and wave soldering per IPC-J-STD-020 and IPC-J-STD-006 standards.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input requiring −225 mA base current to saturate at −4.5 A collector current.
2	Collector	Main high-side power terminal; electrically tied to pin 4 for enhanced thermal and current handling.
3	Emiter	Reference node for PNP operation; connected to higher potential rail in high-side switch configuration.
4	Collector	Second collector terminal-bonded internally to pin 2 to reduce thermal resistance and increase current capacity.

Key Features

Feature	Design Value
Low V_CEsat	−210 to −375 mV at −4.5 A/−225 mA ensures <1 W conduction loss in high-current switching nodes.
High h_FE at high I_C	120–170 at −4 A enables simplified driver design with lower base current requirements.
Enhanced thermal performance	R_th(j-sp) = 15 K/W to solder point allows direct thermal coupling to PCB copper for passive cooling.
Robust SOA	−9 A peak I_CM and 150 °C T_j rating support surge-tolerant operation in motor and power supply start-up conditions.
Small PCB footprint	SOT223 outline (7.3 × 6.7 mm) occupies ~50% less area than TO-220 alternatives while delivering comparable current capability.

Applications

Use Scenario: Drives the gate of high-voltage N-channel MOSFETs in half-bridge or H-bridge motor controllers.

IC Role / Device Role / Timing Role: Level-shifting PNP switch that pulls gate low during dead-time or provides active pull-down in bootstrap circuits.

Use Value: Fast 320 ns t_off and −4.5 A I_C ensure reliable gate discharge under high capacitive loads (>4 nF) without shoot-through risk.

High-Voltage Motor Control

Automotive HVAC Blower Drivers

Use Scenario: Controls field windings or braking paths in 48 V mild-hybrid and industrial BLDC motor systems.

IC Role / Device Role / Timing Role: High-side current switch in regenerative braking or dynamic braking circuits.

Use Value: −60 V V_CEO withstands inductive kickback up to 55 V, eliminating need for external clamping in 48 V systems.

Use Scenario: Powers HVAC blower motors in passenger vehicles where space, thermal management, and EMI are critical.

IC Role / Device Role / Timing Role: Primary switching element in PWM-controlled linear fan drivers meeting ISO 7637-2 pulse 5a immunity.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP high-current switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT3906LT1G	Lower −40 V V_CEO, −200 mA I_C, higher V_CEsat (>300 mV at −100 mA)-not suitable for >24 V or >1 A loads.	Limited to signal-level logic inversion or low-power biasing; cannot replace PBSS304PZ,135 in power switching.	Select only for sub-100 mA, <24 V general-purpose amplification-not for power switching.
ZXTN25050DFHTA	−50 V V_CEO, −5 A I_C, but higher R_CEsat (100–140 mΩ) and slower t_off (500 ns); SOT223-4 package same footprint.	Acceptable in 48 V DC-DC if efficiency loss <0.8% is tolerable; requires larger base drive due to lower h_FE at high I_C.	Use when slightly higher voltage margin (−50 V) is acceptable and thermal budget allows +0.3 W extra loss.

Compared with MMBT3906LT1G, PBSS304PZ,135 delivers 22× higher current and 2× higher voltage blocking; versus ZXTN25050DFHTA, it achieves 30% lower conduction loss and 36% faster turn-off-critical for high-frequency, high-efficiency power stages.

FAQ

What is the maximum continuous collector current for PBSS304PZ,135 under standard FR4 PCB conditions?

The maximum continuous collector current is −4.5 A when mounted on an FR4 PCB with single-sided copper, tin-plated, and standard footprint (per Table 5, limiting values). This rating assumes ambient temperature ≤25 °C and accounts for thermal resistance of 179 K/W junction-to-ambient. Derating applies above 25 °C per Figure 1 power curves.

Can PBSS304PZ,135 be used as a direct replacement for PBSS304NZ in complementary circuits?

No-PBSS304PZ,135 is a PNP device while PBSS304NZ is its NPN complement. They are not interchangeable but are designed to operate together in push-pull or totem-pole configurations. Their matching V_CEsat, h_FE, and thermal characteristics enable balanced performance in bidirectional switching stages.

What is the significance of the dual-collector pin configuration (pins 2 and 4) in SOT223?

Pins 2 and 4 are internally connected to the same collector node, providing doubled bond-wire cross-section and extended thermal path to the PCB. This reduces effective R_th(j-sp) to 15 K/W and increases peak current handling-critical for sustaining −9 A I_CM pulses without thermal runaway.

Does PBSS304PZ,135 meet AEC-Q101 requirements for automotive use?

Yes-PBSS304PZ,135 is qualified to AEC-Q101 Rev D for discrete semiconductors. It undergoes stress testing including HTGB, HTRB, temperature cycling, and mechanical shock per automotive reliability standards, making it suitable for under-hood and cabin applications like HVAC and body control modules.
