Product details
Overview
PBSS8110AS,126 from NXP Semiconductors is a 100 V, 1 A NPN low-VCEsat BISS transistor in SOT54 (TO-92) through-hole package, featuring 200 mΩ equivalent on-resistance and 200 mV VCEsat at 1 A/100 mA drive, used for high-efficiency DC/DC converter switching and automotive 42 V power line control.
For engineers reviewing the PBSS8110AS,126 datasheet, PBSS8110AS,126 pinout, PBSS8110AS,126 application, or PBSS8110AS,126 equivalent, key selection criteria include verified VCEsat ≤ 200 mV at 1 A, RCEsat = 165–200 mΩ, ICM = 3 A peak, Tj = 150 °C max, and SOT54 mechanical compatibility with legacy TO-92 footprints.
Technical Context
This NPN BISS (Breakdown-Immune Super-Saturation) transistor delivers enhanced saturation performance over standard bipolar devices via optimized epitaxial layer design and emitter geometry, enabling lower conduction losses in medium-power switching applications. Its 100 V VCEO rating and 120 V VCBO support robust operation in 42 V automotive systems and telecom supply rails.
The device operates with DC collector current up to 1 A and peak current up to 3 A, supported by thermal resistance Rth(j-a) = 150 K/W on FR4 PCB (single-sided copper), and maintains hFE ≥ 80 at 1 A, ensuring stable gain under full-load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - supports 42 V automotive systems with 2× safety margin against transients |
| IC (DC) | 1 A - continuous switching capability for LED drivers and relay coils |
| ICM | 3 A - enables short-duration surge handling in motor and buzzer drive |
| VCEsat @ 1 A | 200 mV - reduces conduction loss to 200 mW at full load, minimizing heatsink need |
| RCEsat | 165–200 mΩ - quantifies effective on-state resistance for loss modeling in power stages |
| hFE @ 1 A | 80 min - ensures sufficient base drive margin for reliable saturation in discrete switch designs |
| Tj max | 150 °C - allows operation in under-hood automotive environments and sealed industrial enclosures |
Pinout & Package
SOT54 (TO-92) plastic single-ended leaded through-hole package with 3 leads, standardized footprint per JEDEC TO-92 outline, compatible with manual soldering and wave soldering processes on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Collector | Main current path input; connected to switched high-side rail or inductive load return |
| 2 | Base | Control terminal requiring 100 mA DC drive for full saturation at 1 A collector current |
| 3 | Emitter | Reference node for bias and current sensing; tied to system ground or low-side return path |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | 200 mV at 1 A/100 mA drive - cuts conduction loss by >50% vs. standard bipolar transistors |
| High ICM | 3 A peak - sustains inrush currents in relay and solenoid switching without secondary protection |
| BISS architecture | Breakdown-immune saturation design - prevents secondary breakdown during inductive turn-off |
| Thermal robustness | Rth(j-a) = 150 K/W on FR4 - enables 830 mW dissipation at 25 °C ambient without forced cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low-VCEsat transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZTX851 | VCEO = 60 V, VCEsat = 300 mV @ 1 A, RCEsat ≈ 300 mΩ | Not suitable for 42 V automotive or 100 V telecom rails due to lower voltage rating | Select only for ≤36 V industrial or consumer applications where cost is prioritized over efficiency |
| MJD127 | VCEO = 100 V, but TO-220 package, VCEsat = 1.2 V @ 1 A, RCEsat ≈ 1.2 Ω | Requires heatsink and PCB area; unsuitable for space-constrained SOT54-replacement designs | Choose only when higher power dissipation (>2 W) or surface-mount incompatibility mandates TO-220 form factor |

FAQ
What is the maximum continuous collector current for PBSS8110AS,126?
The PBSS8110AS,126 supports a maximum continuous collector current (IC) of 1 A at Tamb ≤ 25 °C with standard FR4 PCB mounting. Derating applies above 25 °C ambient, following the specified thermal resistance of 150 K/W. This rating is validated per IEC 60134 limiting values and confirmed in the 2004 product data sheet.
Does PBSS8110AS,126 have a documented pin-to-pin replacement?
No documented pin-to-pin replacement for PBSS8110AS,126 is published by NXP. While ZTX851 and MJD127 serve similar NPN switching functions, neither matches its SOT54 footprint, 100 V rating, and 200 mV VCEsat simultaneously. Any substitution requires validation of mechanical fit, thermal performance, and electrical behavior in the target circuit.
What is the typical VCEsat of PBSS8110AS,126 at 1 A collector current?
The typical VCEsat of PBSS8110AS,126 is 200 mV at IC = 1 A and IB = 100 mA, as specified in the Characteristics table of the official NXP product data sheet. This value is measured at Tj = 25 °C and reflects the device's BISS architecture optimized for minimal saturation voltage.
Can PBSS8110AS,126 be used in automotive 42 V systems?
Yes, PBSS8110AS,126 is explicitly qualified for automotive 42 V power applications per its 100 V VCEO rating and 120 V VCBO, which exceed ISO 7637-2 load-dump transient requirements. Its 150 °C junction temperature rating and robust BISS structure further support under-hood deployment without derating.
What package type does PBSS8110AS,126 use?
PBSS8110AS,126 uses the SOT54 plastic single-ended leaded (through-hole) package, also known as TO-92 or SC-43A. Its dimensions and pinning (1 = collector, 2 = base, 3 = emitter) conform to JEDEC standards and match legacy TO-92 footprints for drop-in compatibility in existing designs.
