Product details
Overview
PBSS5160K,115 from Nexperia is a surface-mount NPN bipolar junction transistor optimized for high-voltage switching in DC-DC converters, motor drivers, and industrial power supplies. It features 60 V VCEO, 1 A IC, 100 hFE at 500 mA, 1.1 W Ptot, and SOT-223 package with thermal pad for enhanced heat dissipation.
For engineers reviewing the PBSS5160K,115 datasheet, PBSS5160K,115 pinout, PBSS5160K,115 application, or PBSS5160K,115 equivalent, key selection criteria include collector-emitter breakdown voltage, saturation voltage at rated current, DC current gain linearity, thermal resistance to ambient under PCB-mounted conditions, and compatibility with standard FR4 reflow profiles.
Technical Context
This NPN transistor operates in linear or saturated switching mode with guaranteed VCE(sat) ≤ 250 mV at IC = 500 mA and IB = 50 mA. Its base-emitter on-voltage is specified at 1.1 V under same conditions, enabling direct drive from 3.3 V or 5 V logic without external level-shifting.
The device uses an epitaxial planar die structure with integrated emitter ballasting for current uniformity. Its SOT-223 package features a thermally enhanced copper leadframe and exposed collector tab soldered directly to PCB copper for Rth(j-a) = 70 °C/W (standard footprint) and Rth(j-c) = 8.5 °C/W (with 1 cm² 2-oz copper pad).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - supports 48 V nominal bus systems with 25 % safety margin against transients |
| IC | 1 A continuous - enables single-transistor switching for loads up to 48 W at 48 V |
| VCE(sat) | ≤ 250 mV @ IC = 500 mA, IB = 50 mA - minimizes conduction loss and self-heating during PWM on-state |
| hFE | 100 @ IC = 500 mA - ensures stable current amplification with low base drive overhead |
| Ptot | 1.1 W @ Tamb = 25 °C - defines maximum steady-state power dissipation before thermal derating begins |
| Rth(j-a) | 70 °C/W - quantifies junction-to-ambient thermal resistance using JEDEC-standard 2-layer FR4 board |
| ton/toff | 25 ns / 150 ns - supports PWM switching up to 2 MHz with minimal dead-time penalty |
Pinout & Package
SOT-223 package with 4-pin configuration: three leads plus exposed collector thermal pad. Mounting requires soldering the collector tab to ≥1 cm² of 2-oz copper for rated thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-side return path; must handle full load current with <10 mΩ trace resistance |
| 2 (Base) | Control input | Driven by MCU GPIO or gate driver; requires 50 mA peak base current for full saturation at 500 mA collector |
| 3 (Collector) | High-side switched output | Connected to load supply rail; electrically and thermally tied to PCB copper pad for heat spreading |
| 4 (Collector Tab) | Thermal & electrical connection | Not electrically isolated - must be routed as part of collector net and soldered to solid copper pour |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage capability | 60 V VCEO enables use in 48 V automotive and industrial power rails without series stacking |
| Low saturation voltage | VCE(sat) ≤ 250 mV reduces conduction loss to <125 mW at 500 mA, improving efficiency in battery-powered systems |
| Thermally robust package | SOT-223 with exposed collector pad achieves Rth(j-c) = 8.5 °C/W, allowing >800 mW dissipation with minimal heatsink area |
| Logic-level compatible | VBE(on) = 1.1 V permits direct drive from 3.3 V microcontrollers without base resistors exceeding 10 kΩ |
| Fast switching | 25 ns turn-on time supports high-frequency PWM control in Class-D amplifiers and SMPS feedback loops |
Applications
| Industrial Motor Control | 48 V DC-DC Conversion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZTX653 | Higher VCEO (100 V), lower hFE (60 min), TO-92 package | Requires through-hole assembly; unsuitable for high-density SMT layouts or thermal pads | Choose ZTX653 only when higher voltage margin is critical and board space/thermal constraints allow TO-92 mounting. |
| MMBT5551 | Lower VCEO (160 V), lower IC (600 mA), SOT-23 package, no thermal pad | Limited to <300 mW dissipation; cannot sustain 1 A continuous without significant derating | Select MMBT5551 only for low-power signal switching where 600 mA max current and 350 mW Ptot are sufficient. |
Compared with PBSS5160K,115, ZTX653 trades SMT compatibility and thermal performance for higher voltage headroom, while MMBT5551 sacrifices current capacity and thermal management for ultra-compact size-neither offers the balanced 60 V / 1 A / SOT-223 thermal profile of PBSS5160K,115.

FAQ
What is the maximum continuous collector current for PBSS5160K,115?
The PBSS5160K,115 is rated for 1 A continuous collector current (IC) at Tamb = 25 °C with proper PCB thermal management. Derating applies above 25 °C ambient, reaching zero current at 150 °C junction temperature. This rating assumes the collector tab is soldered to ≥1 cm² of 2-oz copper per JEDEC standards.
Does PBSS5160K,115 support logic-level base drive from a 3.3 V microcontroller?
Yes, PBSS5160K,115 has a typical VBE(on) of 1.1 V at IC = 500 mA and IB = 50 mA, making it compatible with direct 3.3 V GPIO drive using a 47 kΩ base resistor. The device achieves full saturation with base current as low as 5 mA at 100 mA collector load, simplifying interface design.
What is the thermal resistance from junction to ambient for PBSS5160K,115?
The PBSS5160K,115 has a junction-to-ambient thermal resistance (Rth(j-a)) of 70 °C/W when mounted on a standard 2-layer FR4 PCB per JEDEC JESD51-3. With a 1 cm² 2-oz copper pad under the collector tab, Rth(j-a) improves to 50 °C/W, enabling higher sustained power dissipation without forced cooling.
Can PBSS5160K,115 replace older SOT-23 transistors like MMBT5551 in existing designs?
No - PBSS5160K,115 uses SOT-223 packaging with different pinout, thermal pad, and higher current capability. Direct replacement would require PCB layout changes, including enlarged copper pour and modified footprint. Its superior thermal performance and 1 A rating make it suitable for upgrades, but not drop-in swaps.
What is the typical saturation voltage VCE(sat) of PBSS5160K,115 at full rated current?
The PBSS5160K,115 exhibits VCE(sat) ≤ 250 mV at IC = 500 mA and IB = 50 mA, and ≤ 350 mV at IC = 1 A and IB = 100 mA. These values ensure low conduction losses in high-duty-cycle switching applications such as motor H-bridge top switches and active clamp circuits.
