Product details

Overview

PBSS305PD,115 from NXP Semiconductors is a PNP low-V_CEsat Breakthrough In Small Signal (BISS) transistor in SOT457 (SC-74) package, rated for −100 V V_CEO, −2 A continuous I_C, and 88–125 mΩ R_CEsat at I_C = −2 A / I_B = −200 mA. It serves as a high-efficiency high-voltage switch in DC-DC converters, MOSFET gate drivers, and automotive power stages.

For engineers reviewing the PBSS305PD,115 datasheet, PBSS305PD,115 pinout, PBSS305PD,115 application, or PBSS305PD,115 equivalent, key selection criteria include verified low saturation resistance, thermal performance on ceramic PCBs (R_th(j-a) = 113 K/W), high h_FE ≥145 at I_C = −1 A, and six-terminal collector-dominant layout for parallel current handling.

Technical Context

This BISS transistor uses an optimized PNP epitaxial structure to achieve sub-250 mV V_CEsat at −2 A with −200 mA base drive, enabling reduced conduction loss in high-side switching topologies. Its dual-collector configuration (pins 1,2,5,6) supports current sharing and thermal spreading across the SOT457 footprint.

It operates with guaranteed h_FE of 55–75 at I_C = −2 A and V_CE = −2 V, and exhibits f_T = 110 MHz - sufficient for fast-switching applications up to several hundred kHz. Switching times are characterized with t_on = 210 ns and t_off = 366 ns under −2 A load conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−100 V: Enables use in 80 V bus systems with 20 % safety margin
I_C (cont.)	−2 A: Supports sustained load current without derating on FR4 with 6 cm² collector pad
R_CEsat	88–125 mΩ: Reduces conduction loss to ≤0.5 W at −2 A, lowering thermal stress
h_FE	55–75 @ I_C = −2 A: Ensures reliable saturation with modest base drive (I_B/I_C = 0.1)
t_off	366 ns: Allows PWM operation up to ~300 kHz with minimal dead-time overhead
f_T	110 MHz: Confirms adequate small-signal gain for high-speed switching control loops
P_tot (ceramic)	1.1 W: Permits 1.1 W dissipation on Al₂O₃ PCB, supporting higher ambient temperatures

Pinout & Package

SOT457 (SC-74) 6-lead surface-mount plastic package with exposed collector terminals for thermal and current handling; dimensions: 3.1 × 2.7 × 1.3 mm (L × W × H), pitch = 0.95 mm.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6	Collector	Four parallel collector terminals reduce effective R_CEsat and improve thermal path to PCB
3	Base	Single base input controlling all collector paths; requires −200 mA for full −2 A saturation
4	Emitter	Common emitter reference; tied to system ground or negative rail in high-side configurations

Key Features

Feature	Design Value
Low V_CEsat	−175 to −250 mV at −2 A/−200 mA enables >98 % efficiency in 12–48 V switching stages
High I_C capability	−2 A continuous rating with −3 A peak allows robust motor and fan drive without external paralleling
High h_FE at high current	Min 55 at −2 A ensures stable saturation even with base drive tolerance or temperature drift
Thermal resistance	R_th(j-a) = 113 K/W on ceramic PCB enables operation at T_amb = 100 °C with <1.1 W dissipation
Small PCB footprint	SOT457 occupies 8.4 mm² - 40 % less area than TO-236 while delivering comparable current

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
PN2222A	V_CEO = −40 V, I_C = −800 mA, R_CEsat ≈ 1 Ω - significantly lower voltage/current capability	Only suitable for ≤30 V logic-level switching; cannot replace PBSS305PD in 48 V+ systems	Select only for low-voltage, low-power signal switching where cost is primary concern.
MBT3906DW1T1G	Dual PNP in SOT-363; each device rated −40 V / −200 mA - no single-device match for −100 V / −2 A	Limited to dual low-current bias or logic functions; lacks thermal and current capacity for power switching	Use only when space-constrained dual-channel biasing is required; not a functional substitute.

Compared with PN2222A and MBT3906DW1T1G, PBSS305PD,115 uniquely delivers −100 V blocking, −2 A current, and sub-125 mΩ R_CEsat in a single SOT457 package - enabling compact, thermally efficient high-voltage switching unattainable with legacy or dual transistors.

FAQ

What is the maximum safe operating junction temperature for PBSS305PD,115?

The absolute maximum junction temperature (T_j) is 150 °C per the datasheet limiting values table. Operation above this threshold risks permanent degradation of h_FE and increased leakage. Derating is required above 25 °C ambient - for example, maximum continuous power drops to 600 mW on standard FR4 at 70 °C ambient.

Can PBSS305PD,115 be used in linear (analog) mode, such as constant-current sources?

Yes - its specified h_FE range (55–75 at −2 A) and low V_CEsat variation support stable linear operation. However, power dissipation must remain within P_tot limits: ≤1.1 W on ceramic PCB or ≤750 mW on FR4 with 6 cm² collector pad. Thermal design is critical to avoid thermal runaway.

Is PBSS305PD,115 pin-compatible with its NPN complement PBSS305ND?

No - although both use SOT457, their pinouts differ. PBSS305PD (PNP) has pins 1/2/5/6 as collectors, pin 3 as base, and pin 4 as emitter. PBSS305ND (NPN) reverses polarity but retains identical physical pin mapping - meaning collector/emitter roles are swapped, requiring board layout revision for direct substitution.

Does PBSS305PD,115 require a base resistor when driven by a 3.3 V microcontroller GPIO?

Yes - a series base resistor is mandatory. With V_BEsat ≈ −0.85 V and required I_B = −200 mA for −2 A saturation, a 3.3 V GPIO would need R_B ≈ (3.3 − 0.85) V / 200 mA = 12.3 Ω. Use a 12 Ω, 1 W resistor with appropriate thermal relief on PCB.
