Product details
Overview
PBSS4032SPN from Nexperia is a dual NPN/PNP low VCEsat Breakthrough In Small Signal (BISS) transistor in SOT96-1 (SO8) package, rated for 30 V VCEO, 5.7 A NPN and −4.8 A PNP continuous collector current, with RCEsat as low as 45 mΩ (NPN) and 65 mΩ (PNP) at 4 A, used in high-efficiency DC-DC converters and battery power management circuits.
For engineers reviewing the PBSS4032SPN datasheet, PBSS4032SPN pinout, PBSS4032SPN application, or PBSS4032SPN equivalent, this device supports compact, thermally efficient switching in dual-polarity load control, synchronous rectification, and bidirectional current handling where low conduction loss and fast switching are critical.
Technical Context
This dual BISS transistor integrates complementary NPN and PNP structures on a single die in an SO8 package, enabling matched thermal behavior and tightly coupled switching characteristics. Its architecture delivers low saturation resistance via optimized epitaxial layer design and emitter ballasting, supporting high-current operation without external current-sharing components.
The device operates with independent base drive for each transistor, allowing asynchronous or synchronous control modes. Switching times-td = 35 ns (NPN), ts = 150 ns (NPN), toff = 215 ns (NPN); td = 30 ns (PNP), ts = 140 ns (PNP), toff = 220 ns (PNP)-are specified under defined pulse conditions (tp ≤300 μs, duty ≤0.02), confirming suitability for high-frequency (>100 kHz) power conversion topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 30 V (NPN), −30 V (PNP): Maximum safe blocking voltage across collector-emitter with base open; defines usable input/output voltage range in switching applications. |
| IC | 5.7 A (NPN), −4.8 A (PNP): Continuous DC collector current rating; sets maximum steady-state load current per transistor without derating. |
| RCEsat | 45–62.5 mΩ (NPN), 65–98 mΩ (PNP) at IC = ±4 A: Low saturation resistance directly reduces conduction loss and junction heating in high-current switches. |
| hFE | 200–500 (NPN), 40–380 (PNP) at IC = ±0.5–±2 A: High DC current gain enables low base drive current requirements, easing driver design and reducing gate-drive losses. |
| fT | 140 MHz (NPN), 115 MHz (PNP): Transition frequency confirms high-speed small-signal amplification capability and supports fast switching transitions. |
| toff | 215 ns (NPN), 220 ns (PNP): Total turn-off time under standardized test conditions; determines minimum dead-time requirements in bridge configurations. |
| Ptot | 0.86 W (FR4, standard footprint), up to 2.3 W (ceramic PCB): Total power dissipation limit defines thermal design envelope and heatsinking needs. |
Pinout & Package
SOT96-1 (SO8) is an 8-lead, medium-power surface-mount plastic package with 1.27 mm lead pitch, 3.9 mm body width, and exposed collector pads for enhanced thermal performance. Pin 1 is indexed, and the package supports reflow and wave soldering per JEDEC standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (TR1, NPN) | Low-impedance emitter connection for NPN transistor; referenced to ground in low-side switch configuration. |
| 2 | Base (TR1, NPN) | Control input for NPN transistor; requires ~0.4 A base current to fully saturate at 4 A collector current. |
| 3 | Emitter (TR2, PNP) | Emitter connection for PNP transistor; typically tied to positive rail in high-side switch configuration. |
| 4 | Base (TR2, PNP) | Control input for PNP transistor; negative base current required for turn-on; polarity-sensitive drive interface. |
| 5, 6 | Collector (TR2, PNP) | Shared high-current output node for PNP; electrically connected internally; used for high-side load connection. |
| 7, 8 | Collector (TR1, NPN) | Shared high-current output node for NPN; electrically connected internally; used for low-side load connection. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | As low as 90 mV (NPN) and −115 mV (PNP) at 1 A/50 mA drive-reduces conduction loss by >40% vs. standard bipolar transistors. |
| High current gain at high IC | hFE ≥ 200 at IC = 4 A (NPN), ≥ 60 at IC = −4 A (PNP)-enables direct microcontroller drive without intermediate buffer stages. |
| Optimized switching speed | Turn-on/off times < 220 ns with controlled storage time-supports >500 kHz PWM frequencies in synchronous buck/boost converters. |
| Thermal efficiency | Rth(j-a) = 55 K/W (FR4, 1 cm² collector pad)-enables 1.4 W dissipation without external heatsink in space-constrained PCB layouts. |
| PCB area reduction | Single SO8 replaces two discrete SOT23/SOT223 devices-saves ≥40% board area while improving thermal coupling and layout symmetry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-polarity switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PBSS4042SPN | Higher VCEO (40 V), lower RCEsat (35 mΩ NPN / 50 mΩ PNP), same SO8 package. | Better suited for 36 V automotive or industrial bus applications requiring higher voltage margin. | Select when system bus voltage exceeds 30 V or when <40 mΩ RCEsat is mandatory for thermal budget. |
| ZXTD0905N | Lower IC (3 A NPN / −2.5 A PNP), smaller SOT363 package, higher RCEsat (80–120 mΩ). | Targeted at space-constrained consumer electronics with <2 A loads and <1 MHz switching. | Choose only for ultra-compact designs where 5.7 A current capability is unnecessary and board area is premium. |
Compared with PBSS4032SPN, PBSS4042SPN offers higher voltage headroom and lower conduction loss at cost of slightly higher price, while ZXTD0905N trades current capacity and thermal performance for miniaturization-making PBSS4032SPN the optimal balance for 24–30 V, 3–5 A industrial power stages.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum base current is 1 A per transistor, as specified in Table 6 Limiting Values. However, typical drive conditions use IB = 0.4 A for NPN (at IC = 4 A) and IB = −0.4 A for PNP to achieve full saturation with margin. Exceeding 1 A risks metallization failure or bond wire overheating even with short pulses.
Can PBSS4032SPN be used in linear regulator applications?
No-it is not characterized or qualified for linear operation. The device lacks guaranteed Safe Operating Area (SOA) curves beyond pulsed conditions, and its thermal resistance (Rth(j-a) ≥ 55 K/W) limits continuous power dissipation to ≤1.4 W. Linear regulation would require stable DC biasing and SOA compliance, which are outside its design scope.
How are the two transistors electrically isolated within the SO8 package?
The NPN (TR1) and PNP (TR2) share no internal electrical connection-their collectors, emitters, and bases are fully isolated except for common thermal substrate. Pin 1/2 (TR1) and Pin 3/4/5/6 (TR2) form separate signal domains. This allows independent biasing, floating high-side PNP operation, and true complementary switching without cross-conduction risk.
Is the 115 in PBSS4032SPN,115 a date code or packaging indicator?
The "115" is a packing code indicating 1000-unit tape-and-reel packaging per Table 9, not a date code. It corresponds to the last three digits of the 12NC ordering code and specifies 8 mm tape width, 12 mm reel diameter, and EIA-481-compliant carrier tape-critical for automated SMT placement compatibility.
