Product details
Overview
PBRN123EK,115 from Nexperia is an NPN resistor-equipped transistor (RET) in SOT346 (SC-59A/TO-236) package, designed for medium-current switching with 40 V VCEO, 600 mA continuous output current, and low 25 mV typical VCEsat at 50 mA. It integrates matched 2.2 kΩ bias resistors (R1 = R2) and targets automotive and industrial digital load control.
For engineers reviewing the PBRN123EK,115 datasheet, PBRN123EK,115 pinout, PBRN123EK,115 application, or PBRN123EK,115 equivalent, key selection criteria include verified VCEsat performance at 600 mA, ±10% R2/R1 ratio tolerance, thermal resistance of 500 K/W on FR4 PCB, and SOT346-compatible footprint for high-density surface-mount assembly.
Technical Context
This BISS (Breakthrough In Small Signal) RET uses a monolithic NPN silicon structure with integrated base bias network (R1 = 2.2 kΩ, R2 = 2.2 kΩ) to eliminate external resistors. Its low VCEsat enables efficient switching in 3.3 V–5 V logic-driven loads, while hFE of 350–560 at IC = 600 mA supports robust saturation under high-current conditions.
The device operates across −65 °C to +150 °C ambient range with 150 °C maximum junction temperature. Absolute maximum ratings include 40 V VCEO, 10 V VEBO, and 600 mA DC output current - validated for FR4 PCB mounting with standard footprint and tin-plated copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum collector-emitter voltage before breakdown; ensures safe operation in 24 V automotive and 36 V industrial supply rails. |
| IO (DC) | 600 mA - Continuous output current rating on FR4 PCB; defines maximum steady-state load drive capability without derating. |
| VCEsat (typ) | 25 mV @ IC = 50 mA, IB = 2.5 mA - Ultra-low saturation voltage minimizes conduction loss and self-heating in logic-level switching. |
| R1 / R2 | 2.2 kΩ / 2.2 kΩ - Matched internal bias resistors reduce component count and ensure consistent turn-on behavior across production lots. |
| R2/R1 ratio | 0.9–1.1 - ±10% tolerance guarantees predictable input impedance and stable switching thresholds in digital interface circuits. |
| hFE | 350–560 @ IC = 600 mA - High DC current gain maintains deep saturation even with limited base drive, easing microcontroller GPIO design. |
| Ptot | 250 mW @ Tamb ≤ 25 °C - Power dissipation limit on standard FR4 PCB; sets thermal boundary for continuous operation without heatsinking. |
Pinout & Package
SOT346 (SC-59A/TO-236) plastic surface-mounted package, 3-lead, dimensions 3.0 × 1.7 × 1.3 mm (L × W × H), with gull-wing leads and standard reflow footprint per Figure 18.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level drive (VI(on) = 1.0–2.0 V) with built-in current limiting via R1. |
| 2 | GND (emitter) | Common reference node; ties emitter directly to ground plane, enabling low-inductance return path for switched loads. |
| 3 | output (collector) | High-current output terminal; rated for 600 mA DC and 800 mA pulsed; connects to load cathode or low-side switch node. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | 25 mV typical at 50 mA enables <10 mW conduction loss in 5 V logic interfaces, reducing thermal stress in dense layouts. |
| Integrated bias network | R1 = R2 = 2.2 kΩ eliminates two external resistors, cutting BOM cost and PCB area while improving assembly yield. |
| High hFE at high current | Min 350 at IC = 600 mA ensures reliable saturation with ≤6 mA base drive, compatible with 3.3 V MCU GPIOs without buffer stages. |
| ±10% R2/R1 tolerance | Guarantees consistent VI(on)/VI(off) thresholds across temperature and process variation, critical for noise-immune digital switching. |
| Automotive-grade reliability | Qualified per AEC-Q101 requirements (inferred from Nexperia's BISS RET family positioning and application notes); supports under-hood use. |

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 |
|---|---|---|---|
| NSV123EJXV6T1G | Same SOT346 package, but R1 = 10 kΩ, R2 = 10 kΩ; higher input impedance; VCEsat = 100 mV @ 100 mA. | Better suited for high-impedance MCU outputs; less suitable for 600 mA continuous loads due to higher saturation voltage. | Select when lower base current (<100 µA) is required and load current ≤200 mA. |
| DTC123YKAT146 | SOT-23 package; R1 = 2.2 kΩ, R2 = 10 kΩ; different R2/R1 ratio (4.55); hFE = 160–320 @ IC = 100 mA. | Lower current gain and asymmetric biasing reduce margin for deep saturation at >300 mA loads. | Choose only for space-constrained designs where SOT-23 footprint is mandatory and peak load ≤300 mA. |
