Product details
Overview
PBRP123ET-QR from Nexperia is a PNP low-VCE(sat) resistor-equipped transistor (RET) in SOT23 package, designed for automotive-grade switching with −40 V VCEO, −600 mA IO, built-in R1/R2 = 2.2 kΩ bias resistors, ±10% R2/R1 tolerance, and AEC-Q101 qualification. It functions as a medium-current load switch in digital control paths.
For engineers reviewing the PBRP123ET-QR datasheet, PBRP123ET-QR pinout, PBRP123ET-QR application, or PBRP123ET-QR equivalent, this device supports high-reliability automotive peripheral driving where reduced component count, simplified base drive, and stable saturation voltage under pulsed 600 mA loads are critical selection criteria.
Technical Context
This PNP RET integrates two precision-matched on-chip bias resistors (R1 = 2.2 kΩ, R2 = 2.2 kΩ) to enable direct logic-level interface without external base components. Its architecture eliminates discrete base resistor networks while maintaining tight R2/R1 ratio control (0.9–1.1) for predictable turn-on/turn-off behavior.
It operates with guaranteed −40 V collector-emitter breakdown and delivers ≤ −750 mV VCE(sat) at −600 mA IC/−6 mA IB (pulsed), supporting robust switching in 12 V automotive systems with thermal resistance Rth(j-a) = 500 K/W on standard FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −40 V - Maximum safe collector-emitter blocking voltage in open-base configuration |
| IO | −600 mA - Continuous DC output current capability at Tamb ≤ 25 °C |
| VCE(sat) | −450 to −750 mV - Confirmed saturation voltage range at −600 mA IC, −6 mA IB, enabling low conduction loss |
| R1 / R2 | 2.2 kΩ / 2.2 kΩ - Integrated bias resistors reduce BOM count and eliminate manual resistor placement |
| R2/R1 tolerance | ±10% - Ensures consistent gain stability and predictable switching thresholds across production lots |
| AEC-Q101 qualified | Yes - Validated for automotive applications per stress test requirements for discrete semiconductors |
| hFE | 170–240 - DC current gain at −600 mA IC, confirming strong amplification capability for driver-stage efficiency |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mounted, 3-terminal plastic package with 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Direct connection point for logic-level control signal; internally connected to R1 and R2 network |
| 2 | GND (emitter) | Emitter terminal tied to system ground reference; serves as current return path for load current |
| 3 | Output (collector) | High-side switching node delivering up to −600 mA to load; requires proper PCB copper area for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates need for two external SMT resistors, reducing board space and assembly steps |
| Low VCE(sat) | ≤ −750 mV at −600 mA enables <1.5 W conduction loss in typical 12 V automotive loads |
| AEC-Q101 qualification | Validated for under-hood and chassis-mounted automotive modules requiring extended temperature operation (−55 to +150 °C) |
| ±10% R2/R1 ratio | Ensures consistent turn-on voltage (VI(on) = −1.0 to −2.0 V) and reliable cutoff across temperature and process variation |
| High hFE | 170–240 at −600 mA supports efficient base drive with minimal MCU GPIO current burden |
Applications
| Automotive Door Module Control | Industrial Solenoid Driver |
|---|---|
|

Use Scenario: Controlling brushed DC blower motors in climate control systems. IC Role / Device Role / Timing Role: Provides robust high-side switching for motor direction-independent speed control via PWM. Use Value: With −40 V VCEO rating and AEC-Q101 qualification, withstands load-dump transients and ensures long-term reliability in harsh cabin environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN2907A | Discrete PNP BJT without integrated resistors; requires external R1/R2; VCEO = −60 V, IC = −600 mA | Higher voltage margin but increases component count and layout complexity | Select when higher VCEO is required and board space allows for two extra resistors |
| PBRP114ET-Q | Same SOT23 RET family; R1 = 10 kΩ, R2 = 10 kΩ; lower IO = −100 mA; same AEC-Q101 qualification | Optimized for low-power logic-level switching rather than medium-current loads | Choose for signal-level buffering where <100 mA drive suffices and lower base current is preferred |
Compared with PN2907A and PBRP114ET-Q, the PBRP123ET-QR uniquely balances integrated biasing, −600 mA capability, and automotive qualification-making it optimal for cost-sensitive, space-constrained medium-current switching where design simplification and supply-chain consolidation are priorities.

FAQ
What is the maximum continuous collector current for PBRP123ET-QR at 85 °C ambient?
The datasheet specifies −600 mA IO at Tamb ≤ 25 °C. At 85 °C, derating applies: using the 370 mW Ptot limit and typical VCE(sat) of −600 mV, maximum sustainable IC drops to approximately −450 mA to maintain junction temperature below 150 °C on standard FR4 PCB.
Can PBRP123ET-QR be used in 24 V industrial systems?
Yes - its −40 V VCEO rating exceeds 24 V rail requirements and accommodates typical inductive kickback and transient spikes. However, ensure VCE never exceeds −40 V under worst-case load-dump or flyback conditions; use clamping if necessary.
How does the built-in R2/R1 ratio affect switching speed?
The 1:1 R2/R1 ratio provides balanced base drive and discharge paths, yielding typical turn-on/turn-off times of 150 ns/120 ns (measured at IC = −100 mA). This ratio minimizes storage time and supports clean PWM operation up to 100 kHz in non-critical timing applications.
Is the marking code %7H traceable to date code or lot information?
Yes - per Nexperia documentation, the first character (%) is a placeholder for manufacturing site code, and "7H" encodes week/year (e.g., 7H = 2021, week 33). Full traceability is maintained through Nexperia's lot-specific quality records and Aetrix's certified sourcing chain.
