Product details
Overview
PBRN123ES,126 from Nexperia is an NPN resistor-equipped transistor (RET) in TO-92 (SOT54) package, designed for medium-current switching with 800 mA output capability, 40 V VCEO, and low 630 mV VCEsat at 800 mA/8 mA drive-used in automotive load control and industrial peripheral drivers.
For engineers reviewing the PBRN123ES,126 datasheet, PBRN123ES,126 pinout, PBRN123ES,126 application, or PBRN123ES,126 equivalent, key selection criteria include verified R1/R2 bias resistor values (2.2 kΩ each), thermal resistance (179 K/W on FR4), collector-emitter saturation voltage across operating current range, and through-hole SOT54 mechanical compatibility.
Technical Context
This BISS (Breakthrough In Small Signal) RET integrates two precision bias resistors (R1 = R2 = 2.2 kΩ, ±10% ratio tolerance) to eliminate external base components and simplify digital interface design. Its NPN structure supports direct TTL/CMOS logic-level drive without additional level-shifting circuitry.
The device operates with VCEO = 40 V and VEBO = 10 V, enabling robust performance in 24 V industrial systems and 12 V automotive environments. Junction temperature rating of 150 °C and ambient range of −65 °C to +150 °C support extended reliability in harsh thermal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum safe collector-emitter voltage under open-base condition; enables use in 24 V supply rails with margin. |
| IO | 800 mA - Continuous DC output current rating; supports driving solenoids, relays, and LED arrays directly. |
| VCEsat @ 800 mA | 0.63 V typical - Low saturation voltage reduces power loss (≤500 mW dissipation at full load) and heat generation. |
| R1 / R2 | 2.2 kΩ / 2.2 kΩ - Integrated input and feedback bias resistors eliminate external components and reduce PCB footprint. |
| hFE @ 800 mA | 340–550 - High DC current gain ensures reliable saturation with minimal base drive current (8 mA). |
| Rth(j-a) | 179 K/W - Thermal resistance on FR4 PCB defines maximum power handling before derating; supports 700 mW at 25 °C ambient. |
| VI(on) | 1.0–2.0 V - On-state input voltage threshold compatible with standard 3.3 V and 5 V logic families. |
Pinout & Package
Package: SOT54 (JEDEC TO-92, JEITA SC-43A), plastic single-ended leaded through-hole package with 3 leads; body length 14.5 mm, lead spacing 2.54 mm, total height ≤5.2 mm.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level drive signal; requires no external pull-up/down. |
| 2 | output (collector) | Main high-current output node; soldered to PCB pad for thermal conduction; rated for 800 mA continuous. |
| 3 | GND (emitter) | Common reference terminal; tied to system ground; forms return path for load current and bias network. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | R1 = R2 = 2.2 kΩ ±30% absolute, 0.9–1.1 ratio tolerance - eliminates two external resistors and associated layout area. |
| Low VCEsat | 630 mV max at 800 mA - cuts conduction loss by >40% vs. standard small-signal transistors, improving efficiency in battery-powered loads. |
| High IO capability | 800 mA continuous - supports direct switching of higher-power peripherals without external driver stages. |
| Automotive-grade reliability | −65 °C to +150 °C operating range and 150 °C junction limit - qualified for under-hood and engine-control module applications. |
| Through-hole mounting | SOT54 package with 2.54 mm lead pitch - enables manual assembly, rework, and high-vibration mechanical retention. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSV123ES,126 | Same SOT54 package, identical R1/R2 values, but optimized for AEC-Q101 automotive qualification with tighter hFE binning. | Required for ASIL-B functional safety subsystems where traceable qualification data is mandated. | Select NSV123ES,126 when automotive OEM compliance documentation (PPAP, test reports) is contractually required. |
| PDTC123ES,115 | SOT346 (SMD) package, same electrical specs, lower Rth(j-a) (500 K/W), but only 600 mA IO rating and no through-hole option. | Suitable for space-constrained PCBs where reflow assembly is preferred and peak current demand stays below 600 mA. | Choose PDTC123ES,115 for high-volume automated production where board density outweighs serviceability needs. |
Compared with PBRN123ES,126, NSV123ES,126 adds automotive qualification overhead without electrical improvement, while PDTC123ES,115 trades mechanical robustness and current headroom for surface-mount compatibility-making PBRN123ES,126 optimal for repairable, high-reliability through-hole designs.

FAQ
What is the maximum continuous collector current for PBRN123ES,126?
The PBRN123ES,126 supports 800 mA continuous output current under standard FR4 PCB conditions (single-sided copper, tin-plated, standard footprint). This rating is confirmed in Table 2 and Table 6 of the official Nexperia datasheet, with derating applied above 25 °C ambient per Figure 2.
Does PBRN123ES,126 require external base resistors?
No, PBRN123ES,126 does not require external base resistors. It integrates R1 = 2.2 kΩ (input) and R2 = 2.2 kΩ (feedback) internally, as specified in Table 2 and Table 8 of the datasheet-enabling direct connection to logic outputs without additional components.
What is the package type and lead configuration of PBRN123ES,126?
PBRN123ES,126 uses the SOT54 package (JEDEC TO-92, JEITA SC-43A), a through-hole plastic single-ended leaded package with three leads arranged in linear order: Pin 1 = input (base), Pin 2 = output (collector), Pin 3 = GND (emitter), per Table 3 and Figure 14.
What is the typical VCEsat of PBRN123ES,126 at full load?
The typical VCEsat of PBRN123ES,126 is 0.63 V at IC = 800 mA and IB = 8 mA, with a maximum of 1.15 V under worst-case conditions. This value is documented in Table 8 under "collector-emitter saturation voltage" and reflects its low-loss switching capability.
Is PBRN123ES,126 suitable for automotive applications?
Yes, PBRN123ES,126 is suitable for automotive applications due to its −65 °C to +150 °C ambient operating range, 150 °C junction temperature limit, and qualification within Nexperia's automotive-grade BISS RET portfolio-commonly deployed in body control modules and lighting systems.
