Product details
Overview
PBRN113EK,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 35 mV typical VCEsat at 50 mA. It integrates R1 = 1 kΩ and R2 = 1 kΩ bias resistors with ±10 % ratio tolerance, enabling direct digital logic interface in automotive and industrial load control circuits.
For engineers reviewing the PBRN113EK,115 datasheet, PBRN113EK,115 pinout, PBRN113EK,115 application, or PBRN113EK,115 equivalent, key selection criteria include its 600 mA DC output rating, 1 kΩ input bias resistor value, SOT346 thermal resistance of 500 K/W (FR4 standard footprint), and verified use in peripheral driver and LED load switching roles.
Technical Context
The PBRN113EK,115 implements a Breakthrough In Small Signal (BISS) NPN structure with monolithically integrated base bias network (R1 and R2) to eliminate external resistors. Its design targets simplified digital-to-analog interface where logic-level inputs directly drive switched loads without discrete base biasing.
It operates with VCE ≤ 40 V and supports IO up to 600 mA under continuous DC conditions on FR4 PCBs, with peak pulsed capability of 800 mA (tp ≤ 1 ms). The 25–35 mV typical VCEsat at low currents enables high-efficiency switching in space-constrained applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum collector-emitter voltage before breakdown; defines safe operating range for 24 V and 36 V system loads. |
| IO (DC) | 600 mA - Continuous output current rating on FR4 PCB with standard footprint; sets maximum steady-state load capacity. |
| VCEsat (typ) | 25 mV @ 50 mA / 2.5 mA - Ultra-low saturation voltage minimizes conduction loss and self-heating in logic-driven switches. |
| R1 | 1 kΩ (0.7–1.3 kΩ) - Integrated input bias resistor enables direct connection to 3.3 V or 5 V CMOS/TTL outputs without external components. |
| R2/R1 | 1.0 ±0.1 - Precise resistor ratio ensures stable current gain and predictable turn-on threshold across temperature. |
| hFE (min) | 40 @ 50 mA - Minimum DC current gain guarantees reliable saturation under worst-case drive conditions. |
| Ptot (max) | 250 mW @ Tamb ≤ 25 °C - Power dissipation limit on standard FR4 board; determines thermal derating requirements. |
Pinout & Package
SOT346 (SC-59A/TO-236) surface-mount plastic package with 3 leads, 1.3 mm max height, and 2.5 × 1.7 mm body footprint. Optimized for reflow soldering per JEDEC J-STD-020.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level voltage (0–10 V) to control transistor switching state. |
| 2 | GND (emitter) | Common reference node; ties emitter to ground plane and serves as return path for base and load currents. |
| 3 | output (collector) | Switched high-side output node; connects to load (e.g., relay coil, LED string) with 600 mA DC capability. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | R1 = 1 kΩ + R2 = 1 kΩ eliminates two external resistors, reducing BOM count and PCB area by ≥3 mm². |
| Low VCEsat | 25 mV typical at 50 mA enables <15 mW conduction loss, critical for thermally constrained modules. |
| ±10 % R2/R1 tolerance | Ensures consistent IC/IB ratio across production lots, minimizing variation in switching thresholds. |
| 800 mA pulsed capability | Supports short-duration inrush or surge loads (e.g., solenoid pull-in) without device failure. |
| JEDEC TO-236 compatible | Enables drop-in replacement in legacy designs using standard SOT23/SOT346 footprints and assembly processes. |
Applications

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 |
|---|---|---|---|
| NSV11301T1G | Higher VCEO (50 V), lower IO (500 mA), R1 = 2.2 kΩ, R2 = 47 kΩ - different bias ratio and lower current capability. | More suitable for higher-voltage but lower-current sensing interfaces than load switching. | Select when >40 V system margin is required and load current stays below 500 mA. |
| MMBT3904LT1G | No integrated resistors; requires external RB; higher VCEO (40 V), same package, but hFE min = 100 - discrete solution with higher gain but added components. | Used where precise base current control or variable gain is needed, not for fixed-ratio logic interface. | Choose only if design requires adjustable base drive or higher hFE stability across temperature. |
Compared with NSV11301T1G and MMBT3904LT1G, the PBRN113EK,115 delivers optimal balance of 600 mA drive strength, ultra-low 25 mV VCEsat, and matched 1 kΩ/1 kΩ bias network - making it uniquely suited for cost-sensitive, space-constrained digital load switching where minimal external components are mandatory.

FAQ
What is the maximum continuous output current rating for PBRN113EK,115?
The PBRN113EK,115 has a maximum continuous output current (IO) of 600 mA when mounted on an FR4 PCB with standard footprint and ambient temperature ≤25 °C. This rating drops with increasing temperature per the published derating curve, reaching zero at 125 °C ambient. The 600 mA value is confirmed in Table 2 and Table 6 of the Nexperia datasheet.
Does PBRN113EK,115 have built-in bias resistors, and what are their values?
Yes, the PBRN113EK,115 integrates two bias resistors: R1 = 1 kΩ (input resistor) and R2 = 1 kΩ (base-emitter resistor), with R2/R1 ratio tightly controlled at 1.0 ±0.1. These values are specified in Table 2 (Quick Reference Data) and Table 8 (Characteristics), enabling direct logic-level drive without external components.
What is the typical collector-emitter saturation voltage (VCEsat) for PBRN113EK,115 at 50 mA collector current?
The typical VCEsat for PBRN113EK,115 is 25 mV at IC = 50 mA and IB = 2.5 mA, as stated in Table 8 of the datasheet. This ultra-low saturation voltage reduces conduction losses and thermal stress, especially important in high-density or thermally limited PCB layouts.
Which package does PBRN113EK,115 use, and is it compatible with standard SOT23 footprints?
The PBRN113EK,115 uses the SOT346 (SC-59A/TO-236) package, which shares mechanical compatibility with SOT23 but has distinct pinout (1=base, 2=emitter, 3=collector). While footprint dimensions overlap, the pin assignment differs - SOT23 variants use 1=emitter, 2=base, 3=collector - so PCB layout must match SOT346-specific land patterns shown in Figure 18 of the datasheet.
Can PBRN113EK,115 be used in automotive applications, and what qualifications support this?
Yes, the PBRN113EK,115 is qualified for automotive body electronics per its inclusion in Nexperia's AEC-Q101-qualified BISS RET portfolio and documented use in automotive segments (Section 1.3 Applications). Its 150 °C junction temperature rating, −65 °C to +150 °C operating range, and robust thermal performance on FR4 PCBs meet typical under-hood environmental requirements.
