Product details
Overview
PBSS8110X,135 from Nexperia is an AEC-Q101-qualified NPN low VCE(sat) transistor in SOT89 package, rated for 100 V VCEO, 1 A continuous collector current, and 200 mΩ typical RCE(sat) at IC = 1 A / IB = 100 mA. It serves as a high-efficiency switching element in automotive 42 V power systems, DC-DC converters, and inductive load drivers where thermal efficiency and low conduction loss are critical.
For engineers reviewing the PBSS8110X,135 datasheet, PBSS8110X,135 pinout, PBSS8110X,135 application, or PBSS8110X,135 equivalent, key selection criteria include verified VCE(sat) performance at 1 A, AEC-Q101 qualification status, SOT89 thermal derating behavior on FR4 vs. ceramic PCBs, and validated base drive requirements for reliable saturation in relay/motor driver topologies.
Technical Context
This device operates as a discrete NPN bipolar junction transistor optimized for low-saturation switching-its 165–200 mΩ RCE(sat) and 80–500 hFE (depending on IC) enable efficient current control with minimal voltage drop across the collector-emitter path. It features a maximum VCEO of 100 V and peak ICM of 3 A for short-pulse inductive loads.
Thermal design is tightly coupled to PCB mounting: Rth(j-a) ranges from 63 K/W (ceramic) to 227 K/W (standard FR4), directly impacting steady-state power handling up to 2 W under defined conditions. Its 150 °C max junction temperature and −65 °C to +150 °C operating range support automotive under-hood deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - Maximum safe collector-emitter voltage with base open; defines breakdown margin in 42 V automotive systems. |
| IC | 1 A continuous - Rated DC collector current enabling direct drive of lamps, relays, and small motors without external heatsinking on adequate PCB copper. |
| RCE(sat) | 165–200 mΩ at IC = 1 A / IB = 100 mA - Low on-resistance reduces conduction loss and self-heating in high-duty-cycle switching. |
| hFE | 80 min at IC = 1 A - Ensures sufficient DC gain for stable base-driven saturation with modest drive current. |
| Tj(max) | 150 °C - Enables operation in engine bay environments; requires thermal management per PCB layout per Figure 1. |
| AEC-Q101 | Qualified - Validated for automotive applications including temperature cycling, HTRB, and ESD robustness per stress test standards. |
Pinout & Package
SOT89 (SC-62 / TO-243) surface-mount plastic package: 4.5 mm × 2.5 mm × 1.5 mm body, 1.5 mm lead pitch, integrated heat-dissipating tab (pin 2, collector).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (E) | Current return path; connected to ground or low-side reference; thermally isolated from collector tab. |
| 2 | Collector (C) | Main power output terminal; electrically and thermally tied to exposed metal tab for PCB heat sinking. |
| 3 | Base (B) | Control input requiring ~100 mA drive for full saturation at 1 A load; sensitive to overdrive-induced storage time penalties. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | 200 mV max at IC = 1 A - Reduces power dissipation by >40% vs. standard BJT alternatives, lowering thermal load in space-constrained modules. |
| AEC-Q101 qualification | Validated for automotive use - Includes HTSL, AC/DC life test, and ESD ≥2 kV HBM, supporting functional safety-aware designs without additional qualification effort. |
| High ICM | 3 A peak (tp ≤ 1 ms) - Supports surge currents in relay coil de-energization and motor startup without secondary protection. |
| Thermal resistance optimization | Rth(j-sp) = 16 K/W - Enables rapid heat transfer from junction to solder point, improving transient thermal response during pulsed operation. |
Applications
| Automotive 42 V Power Distribution | DC-DC Converter Switching Stage |
|---|---|
|
Use Scenario: Solid-state replacement for mechanical fuses and relays in 42 V mild-hybrid vehicle subsystems (e.g., HVAC actuators, seat controls). IC Role / Device Role / Timing Role: Low-side switch controlling load current with fast turn-on/off (<550 ns off-time) and minimal voltage drop during sustained conduction. Use Value: Eliminates contact wear and bounce; enables diagnostic current sensing via VCE(sat) monitoring due to stable, linearized saturation behavior. |
Use Scenario: Main switching transistor in non-isolated buck converter supplying 5 V/3.3 V rails from 42 V battery input. IC Role / Device Role / Timing Role: High-current, low-loss synchronous rectifier alternative in low-frequency (<500 kHz) topologies where MOSFET gate drive complexity is undesirable. Use Value: Achieves >92% efficiency at 1 A output with no gate driver IC, leveraging inherent current gain and predictable saturation timing. |
| Inductive Load Driver (Relays/Buzzers) | LED/Lamp Driver in Low-Voltage Systems |
|
Use Scenario: Driving 24 V/1 A relay coils in industrial PLC I/O modules subject to frequent switching and reverse EMF transients. IC Role / Device Role / Timing Role: Clamped switching element with built-in flyback path handling (via external diode); leverages 100 V VCEO margin against L·di/dt spikes. Use Value: Withstands repetitive 80 V inductive kickback without degradation; storage time <365 ns minimizes cross-conduction risk in H-bridge variants. |
Use Scenario: Constant-current dimming driver for automotive interior LED arrays powered from 12 V or 24 V supplies. IC Role / Device Role / Timing Role: Linear current regulator configured in emitter-follower mode with feedback resistor; exploits tight VBE(sat) tolerance (±50 mV) for ±3% current accuracy. Use Value: Delivers stable brightness across temperature (−40 °C to +125 °C ambient) without digital compensation, reducing BOM count vs. op-amp-based solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low VCE(sat) transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS12201LT1G | VCEO = 60 V, RCE(sat) = 220 mΩ @ 1 A - Lower voltage rating and higher saturation resistance. | Restricted to ≤24 V systems; unsuitable for 42 V automotive or telecom infrastructure. | Select only for cost-sensitive 24 V industrial controls where 100 V margin is unnecessary. |
| Diodes Incorporated DXT75100Q-13 | VCEO = 100 V, RCE(sat) = 190 mΩ @ 1 A, but not AEC-Q101 qualified - identical voltage/current specs but unqualified for automotive. | Lacks automotive reliability validation; requires customer-level qualification for automotive programs. | Prefer for non-automotive telecom or industrial DC-DC where AEC-Q101 is not mandated. |
Compared with NSS12201LT1G and DXT75100Q-13, PBSS8110X,135 uniquely combines 100 V rating, sub-200 mΩ RCE(sat), and AEC-Q101 qualification-making it the only drop-in solution for production automotive 42 V power distribution without derating or requalification.

FAQ
What is the recommended base drive current for full saturation at 1 A collector load?
The datasheet specifies IB = 100 mA for guaranteed VCE(sat) ≤ 200 mV at IC = 1 A under pulsed conditions (tp ≤ 300 µs). For DC operation, maintain IB ≥ 100 mA with adequate PCB copper to limit base lead heating; hFE drops to ~80 at this point, confirming forced β = 10 ensures deep saturation without excessive drive overhead.
Can PBSS8110X,135 be used in parallel for higher current handling?
No-BJTs exhibit positive thermal runaway when paralleled due to decreasing VBE with rising temperature. The device lacks integrated current-sharing features or matched characteristics for parallel operation. For >1 A continuous loads, select a higher-rated single device (e.g., PBSS8115X) or implement active current balancing circuitry.
How does thermal performance differ between FR4 and ceramic PCB mounting?
Rth(j-a) is 227 K/W on standard FR4 (no extra copper), 89 K/W with 6 cm² collector pad, and 63 K/W on Al2O3 ceramic. This means at 1 A/200 mV (200 mW), junction-to-ambient rise is 45 °C on FR4 vs. 13 °C on ceramic-directly affecting maximum ambient operating temperature before hitting 150 °C Tj.
Is a flyback diode required when driving inductive loads?
Yes-PBSS8110X,135 has no internal flyback diode. When switching relays, solenoids, or motors, an external fast-recovery or Schottky diode (e.g., PMEG3010AEJ) must be placed cathode-to-collector to clamp inductive kickback. Failure to do so risks exceeding 100 V VCEO and permanent device failure.
