Product details

Overview

PBSS304PX,115 from Nexperia is a PNP low V_CEsat transistor in SOT89 package, rated for −60 V V_CEO, −4.2 A continuous collector current, and 48–69 mΩ R_CEsat at −4 A/−200 mA drive. It serves as a high-efficiency power switch in automotive high-voltage gate driving and DC-DC conversion circuits.

For engineers reviewing the PBSS304PX,115 datasheet, PBSS304PX,115 pinout, PBSS304PX,115 application, or PBSS304PX,115 equivalent, this device is selected for its AEC-Q101 qualification, low saturation resistance, thermal performance on FR4 and ceramic PCBs, and validated use in motor control and power switching where reduced conduction loss and compact footprint are critical.

Technical Context

This PNP bipolar junction transistor operates with fixed-current gain (h_FE) of 60–100 at −6 A, exhibits fast switching with t_on = 80 ns and t_off = 320 ns under −12.5 V V_CC, and maintains stable V_CEsat down to −220 mV at −4.2 A/−210 mA drive. Its f_T of 130 MHz supports medium-frequency switching applications.

Thermal design is enabled by three defined R_th(j-a) values: 208 K/W (standard FR4), 76 K/W (FR4 with 6 cm² collector pad), and 60 K/W (ceramic Al₂O₃), allowing precise derating per mounting condition. Junction temperature is rated to 150 °C, with storage and ambient ranges spanning −65 to +150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V - Maximum safe collector-emitter voltage with base open; enables use in 48 V automotive and industrial HV rails.
I_C	−4.2 A - Continuous DC collector current rating; supports sustained load switching without thermal runaway under proper heatsinking.
R_CEsat	48–69 mΩ - Low saturation resistance at −4 A/−200 mA; reduces conduction loss to ≤275 mW, minimizing board-level heating.
h_FE	60–100 - DC current gain at −6 A/−2 V; ensures reliable saturation with modest base drive, easing driver circuit design.
t_off	320 ns - Turn-off time under −12.5 V V_CC, −3 A I_C, ±0.15 A base drive; supports PWM frequencies up to ~300 kHz.
f_T	130 MHz - Transition frequency at −10 V V_CE, −100 mA I_C; confirms suitability for medium-speed switching and analog amplification.
C_c	90–120 pF - Collector capacitance at −10 V V_CB; limits high-frequency Miller effect, aiding stability in gate-drive configurations.

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
ON Semiconductor NSS30400PZT1G	V_CEO = −40 V, I_C = −3.5 A, R_CEsat = 60–90 mΩ - Lower voltage/current rating and higher saturation resistance.	Not suitable for 48–60 V systems; limited to 24 V automotive accessories or industrial sensors.	Select only if system voltage ≤40 V and thermal margin allows higher conduction loss.
Diodes Incorporated DXT30400P5-13	V_CEO = −60 V, I_C = −3.5 A, R_CEsat = 55–85 mΩ - Same voltage rating but lower current and less consistent h_FE above 2 A.	Acceptable for non-critical 60 V loads below 3.5 A, but not recommended for AEC-Q101–mandated designs.	Use only in cost-sensitive industrial applications lacking automotive qualification requirements.

Compared with PBSS304PX,115, NSS30400PZT1G trades voltage headroom and efficiency for broader distributor availability, while DXT30400P5-13 offers similar voltage rating but lacks AEC-Q101 validation and delivers 17% higher conduction loss at full load - making PBSS304PX,115 the preferred choice for automotive-grade 48–60 V power switching.

FAQ

What is the maximum allowable base current for continuous operation?

The datasheet specifies I_B = −210 mA at I_C = −4.2 A for V_CEsat testing, but continuous base current must be limited to avoid bond wire overheating. For sustained operation, keep I_B ≤ −150 mA with adequate PCB copper area on pin 3; pulse conditions allow up to −400 mA for ≤300 µs with duty cycle ≤2%.

Can PBSS304PX,115 replace an NPN transistor in the same circuit?

No - PBSS304PX,115 is a PNP device requiring reversed polarity: emitter connects to higher potential, collector to load, and base driven negative relative to emitter. Direct NPN substitution would invert logic and violate biasing; use its NPN complement PBSS304NX,115 instead for identical footprint and mirrored ratings.

How does thermal performance differ between FR4 and ceramic PCB mounting?

On standard FR4, R_th(j-a) is 208 K/W, limiting continuous power to ~0.6 W at 25 °C ambient. With a 6 cm² collector pad, it drops to 76 K/W (1.65 W max). On Al₂O₃ ceramic, R_th(j-a) is 60 K/W, enabling 2.1 W dissipation - a 3.5× improvement over standard FR4, critical for sealed automotive enclosures.

Is the SOT89 package lead-free and RoHS compliant?

Yes - PBSS304PX,115 is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The package uses SnAgCu solderable finish, and marking code %5L includes site-specific identifiers per Nexperia's traceability protocol.
