Product details
Overview
PBRN113ET-QR from Nexperia is a 40 V, 600 mA NPN resistor-equipped transistor (RET) in SOT23 package, designed for automotive-grade switching with built-in 1 kΩ bias resistors (R1 = R2), low 320–550 mV VCE(sat) at 600 mA, and AEC-Q101 qualification. It functions as a medium-current digital switch in load control circuits requiring reduced component count and simplified PCB layout.
For engineers reviewing the PBRN113ET-QR datasheet, PBRN113ET-QR pinout, PBRN113ET-QR application, or PBRN113ET-QR equivalent, this page delivers verified electrical parameters, thermal derating behavior, bias resistor tolerance (±10 %), and automotive-compliant switching performance - critical for ECU output stage design, LED driver staging, and peripheral interface validation.
Technical Context
This NPN RET integrates two precision-matched 1 kΩ on-die base bias resistors (R1 = R2, ratio tolerance ±10 %) to enable single-resistor drive logic compatibility and eliminate external bias network design. Its low saturation voltage (320–550 mV at IC = 600 mA, IB = 6 mA) supports efficient power delivery in thermally constrained automotive modules.
The device operates within a −65 °C to +150 °C ambient range, with junction-to-ambient thermal resistance of 500 K/W (standard FR4 PCB) and 338 K/W (enhanced pad), enabling reliable operation in under-hood environments where thermal management is limited by board area and copper thickness.
Key Specifications

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 |
|---|---|---|---|
| PBRN113ET,115 | No AEC-Q101 qualification; identical electrical specs and SOT23 package | Not approved for automotive production; suitable for industrial prototypes or non-safety-critical consumer designs | Select when automotive qualification is not required and cost sensitivity outweighs long-term reliability assurance |
| NSV11201T1G | Higher VCEO (50 V), lower IO (300 mA), tighter R2/R1 tolerance (±5 %), same SOT23 footprint | Better suited for higher-voltage but lower-current applications such as sensor interface protection or low-power relay driving | Choose when system voltage exceeds 40 V or when tighter resistor matching is needed for precision biasing |
Compared with PBRN113ET-QR, PBRN113ET,115 offers identical performance without automotive qualification, while NSV11201T1G trades current capability for higher voltage rating and improved resistor matching - guiding selection based on voltage headroom, current demand, and qualification requirements.

FAQ
What is the maximum continuous current rating for PBRN113ET-QR under standard PCB conditions?
The PBRN113ET-QR is rated for 600 mA continuous output current when mounted on a standard FR4 PCB (single-sided, 35 μm copper, tin-plated, standard footprint). This rating assumes ambient temperature ≤25 °C and accounts for thermal resistance of 500 K/W. Derating applies above 25 °C per the published power derating curve.
Does PBRN113ET-QR require an external base resistor for logic-level drive?
No. PBRN113ET-QR integrates both R1 (1 kΩ) and R2 (1 kΩ) bias resistors internally, enabling direct connection to 3.3 V or 5 V CMOS/TTL outputs without external components. The input pin (Pin 1) accepts logic-high signals to activate the transistor, with VI(on) specified at 1.0–1.8 V at 20 mA collector current.
How does the AEC-Q101 qualification impact the use of PBRN113ET-QR in industrial applications?
AEC-Q101 qualification ensures PBRN113ET-QR meets rigorous stress-test requirements for temperature cycling, humidity, mechanical shock, and ESD - exceeding typical industrial standards. While not required for industrial use, this qualification provides extended reliability, longer field lifetime, and reduced failure-in-time (FIT) rates, making it ideal for mission-critical or maintenance-intolerant deployments.
Can PBRN113ET-QR be used in parallel configurations to increase current capacity?
Parallel operation is not recommended due to mismatch in VCE(sat) and hFE between units, which causes current imbalance and potential thermal runaway. The device is characterized for single-unit operation only. For higher current needs, select a higher-rated RET (e.g., PBRN213ET-QR) or implement discrete transistor solutions with emitter ballasting resistors.
