Product details
Overview
PBSS4160DSZ from Nexperia is a dual NPN low VCEsat transistor pair in SOT457 (TSOP6) package, designed for high-efficiency switching in space-constrained automotive and industrial control circuits. It delivers 60 V VCEO, 1 A continuous collector current per transistor, 200–250 mΩ RCEsat at IC = 1 A / IB = 100 mA, and AEC-Q101 qualification - enabling use in dual motor/fan drivers where thermal efficiency and PCB area reduction are critical.
For engineers reviewing the PBSS4160DSZ datasheet, PBSS4160DSZ pinout, PBSS4160DSZ application, or PBSS4160DSZ equivalent, key selection criteria include verified dual-transistor pin mapping (E1/B1/C2/E2/B2/C1), low-saturation performance under pulsed 1 A loads, thermal resistance down to 179 K/W on ceramic PCB, and AEC-Q101 compliance for automotive-grade reliability validation.
Technical Context
This device integrates two matched NPN transistors in a single TSOP6 package with shared thermal path and symmetrical layout optimized for dual-switch topologies. Its low RCEsat (200–250 mΩ) and high hFE (100–180 at IC = 1 A) enable efficient operation at high current density without forced cooling.
The pinout supports independent base drive and emitter referencing for each transistor, with collectors assigned to pins 1 and 3 (C1 and C2) and emitters to pins 2 and 4 (E1 and E2). Switching parameters include ton = 90 ns and toff = 500 ns under standardized test conditions (IC = 0.5 A, IBon/IBoff = ±25 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Maximum safe collector-emitter voltage with base open; defines maximum supply rail compatibility in 48 V automotive systems. |
| IC (continuous) | 1 A per transistor - Sustained DC current handling capacity; enables direct driving of small DC motors or fans without external current boosting. |
| RCEsat | 200–250 mΩ at IC = 1 A / IB = 100 mA - Low saturation resistance minimizes conduction loss and heat generation in high-duty-cycle switching. |
| hFE | 100–180 at IC = 1 A - High DC current gain reduces required base drive current, easing MCU GPIO or driver IC interface design. |
| Tj max | 150 °C - Maximum junction temperature; supports operation in under-hood automotive environments with appropriate PCB thermal management. |
| AEC-Q101 | Qualified - Meets stress-test requirements for discrete semiconductors in automotive applications, including temperature cycling and HTRB. |
Pinout & Package
SOT457 (TSOP6) surface-mount plastic package with 6 leads, 1.7 mm width, and 3.0 mm length; optimized for reflow soldering with defined footprint per Figure 16 (sot457_fr) and wave soldering per Figure 17 (sot457_fw).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | C1 | Collector of Transistor 1 - Primary high-side switch node; electrically isolated from C2 but thermally coupled within same die. |
| 2 | E1 | Emitter of Transistor 1 - Reference node for TR1; tied to ground or load return in low-side switch configuration. |
| 3 | C2 | Collector of Transistor 2 - Independent high-side node for second switch leg; enables dual-channel control without cross-coupling. |
| 4 | E2 | Emitter of Transistor 2 - Dedicated return path for TR2; allows separate current sensing or independent grounding schemes. |
| 5 | B2 | Base of Transistor 2 - Direct CMOS/TTL-compatible input; requires ~100 mA base current for full saturation at 1 A collector load. |
| 6 | B1 | Base of Transistor 1 - Mirror-symmetric control input; pin 6 placement supports standard routing from adjacent microcontroller GPIOs. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | 200–250 mV at IC = 1 A - Reduces power dissipation to ≤250 mW per transistor, enabling compact thermal design without heatsinks. |
| Dual NPN pairing | Matched hFE and RCEsat across TR1/TR2 - Ensures balanced current sharing and timing in dual-load applications like H-bridge half-drivers. |
| High peak current | ICM = 2 A (1 ms pulse) - Supports inrush current handling for brushed DC motors and solenoid actuation without device failure. |
| Thermal performance | Rth(j-a) = 179 K/W on Al2O3 PCB - Enables >400 mW total power dissipation at 25 °C ambient, exceeding typical FR4 limits by 40 %. |

|---|---|---|---|
| ON Semiconductor NSS40201MR6T1G | 60 V VCEO, 0.8 A IC, 300 mΩ RCEsat, SOT-563 package (smaller footprint, lower current rating) | Limited to sub-1 A loads; higher RCEsat increases thermal load in sustained operation | Select when PCB area is primary constraint and peak current remains below 0.8 A. |
| Diodes Incorporated DMMT3904W-7-F | 40 V VCEO, 200 mA IC, 350 mΩ RCEsat, SOT-363 package (lower voltage/current, higher saturation) | Not suitable for 48 V or 1 A automotive loads; requires derating in thermal-limited designs | Use only in low-power signal-switching roles, not power switching applications. |
Compared with NSS40201MR6T1G and DMMT3904W-7-F, PBSS4160DSZ delivers 25 % higher continuous current, 20 % lower RCEsat, and AEC-Q101 certification - making it the only option qualified for direct integration into automotive body control modules without additional qualification testing.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum base current (IB) is 300 mA per transistor, but continuous operation above 100 mA is not recommended without thermal derating. At IC = 1 A, the datasheet specifies IB = 100 mA for full saturation - exceeding this increases power dissipation in the base region and risks localized heating, especially on FR4 PCBs.
Can PBSS4160DSZ be used in linear (analog) amplification mode?
No - PBSS4160DSZ is optimized for switching operation, not linear amplification. Its hFE is specified only at high IC (1 A) and pulsed conditions, and thermal characteristics assume switching duty cycles. Linear operation would exceed safe operating area limits due to simultaneous high VCE and IC, risking thermal runaway.
Is the SOT457 package lead-free and RoHS compliant?
Yes - PBSS4160DSZ uses a lead-free, halogen-free, and RoHS-compliant SOT457 package per Nexperia's product compliance documentation. The device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and is rated for standard reflow profiles up to 260 °C peak temperature.
How does thermal resistance change between FR4 and ceramic PCB mounting?
Rth(j-a) improves from 278 K/W (ceramic, standard footprint) to 431 K/W (FR4, standard footprint) - a 55 % increase. This means the same power dissipation raises junction temperature ~85 °C higher on FR4 than on Al2O3. For 1 A continuous operation, ceramic mounting extends usable ambient range by ~30 °C compared to FR4.
