Product details
Overview
PBRP123YT-QR from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 package, rated for −40 V VCEO, −600 mA output current, with integrated bias resistors R1 = 2.2 kΩ and R2 = 10 kΩ (R2/R1 = 4.55), optimized for automotive load switching where low VCEsat (−270 mV typ. at −600 mA) and AEC-Q101 qualification are required.
For engineers reviewing the PBRP123YT-QR datasheet, PBRP123YT-QR pinout, PBRP123YT-QR application, or PBRP123YT-QR equivalent, this device serves as a drop-in replacement for discrete base-resistor transistor configurations in medium-current digital switching, reducing PCB area and assembly cost while maintaining thermal robustness up to 150 °C junction temperature.
Technical Context
This PNP RET integrates two precision bias resistors (R1 = 2.2 kΩ ±30 %, R2/R1 = 4.55 ±10 %) directly into the die substrate, eliminating external base resistors and enabling single-pin control of collector current. Its −40 V VCEO rating and −600 mA continuous output support 12 V automotive rail switching with margin.
The device operates with guaranteed hFE ≥ 190 at −600 mA/−6 mA drive, and achieves VCEsat ≤ −450 mV (max) under pulsed conditions-critical for minimizing conduction loss in high-duty-cycle loads like LED drivers and solenoid interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −40 V - Withstands reverse collector-emitter voltage up to automotive battery transients without breakdown. |
| IO | −600 mA - Continuous DC load current capability suitable for driving relays, LEDs, and small motors. |
| R1 | 2.2 kΩ (1.54–2.86 kΩ) - Sets base current magnitude; enables predictable turn-on with standard logic-level inputs. |
| R2/R1 ratio | 4.55 (4.1–5.0) - Defines feedback ratio for stable saturation and improved noise immunity against leakage currents. |
| VCEsat | −270 mV (typ.) at −600 mA - Reduces power dissipation to <160 mW, easing thermal design on FR4 PCBs. |
| hFE | 190–270 at −600 mA - Ensures sufficient current gain for reliable saturation with minimal base drive overhead. |
| Tj max | 150 °C - Supports operation in under-hood automotive environments without derating below ambient. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, tin-plated terminations compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Internal connection to R1 and R2 network; accepts logic-level control signal (VI(on) ≤ −0.8 V typical). |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path for load current and bias network reference. |
| 3 | Output (collector) | High-current output node; connects to load anode (for high-side switch configuration) or cathode (low-side sink). |
Key Features

| AEC-Q101 qualified | Validated for automotive applications including engine control modules and body electronics per stress test requirements. |
| Low VCEsat | −270 mV typical at full load ensures <160 mW conduction loss, enabling use without heatsinking on standard FR4. |
| ±10 % R2/R1 tolerance | Guarantees consistent saturation behavior across temperature and process variation, improving batch-to-batch reliability. |
| Thermal resistance Rth(j-a) | 338 K/W (with 1 cm² collector pad) allows >300 mW safe continuous dissipation at 25 °C ambient. |

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 |
|---|---|---|---|
| PBRP123YT-Q | Original part; R1 = 2.2 kΩ, R2 = 10 kΩ, AEC-Q101 qualified | Designed for automotive-grade reliability and thermal stability | Select when AEC-Q101 compliance and −40 °C to +150 °C operation are mandatory |
| NSV12300T1G | PNP RET with R1 = 2.2 kΩ, R2 = 10 kΩ, but only industrial temp range (−55 °C to +150 °C), no AEC-Q101 | Suitable for non-automotive industrial use; lower qualification cost | Choose for cost-sensitive consumer or industrial designs where automotive qualification is not required |
Compared with NSV12300T1G, PBRP123YT-QR adds AEC-Q101 validation and tighter R2/R1 tolerance (±10 % vs. ±15 %), making it preferable for safety-critical automotive loads, while retaining identical pinout and electrical specs for seamless migration.

FAQ
What is the maximum continuous collector current for PBRP123YT-QR?
The maximum continuous collector current is −600 mA at Tamb ≤ 25 °C on a standard FR4 PCB with 35 μm copper. Derating applies above 25 °C per the power derating curve: total power dissipation drops to 250 mW at 70 °C ambient and 0 mW at 150 °C.
Can PBRP123YT-QR be used as a high-side switch?
Yes-it is a PNP RET configured for high-side switching: emitter connects to VCC, collector drives the load to ground. Pin 2 (GND/emitter) must be tied to the positive rail, and load connects between pin 3 (collector) and ground. VI(on) ≤ −0.8 V ensures compatibility with 3.3 V or 5 V logic.
How does the built-in R2 resistor improve noise immunity?
R2 provides base-emitter feedback that shunts leakage currents away from the base junction, raising the effective VI(off) threshold to −0.6 V (min). This prevents unintended turn-on from ESD-induced transients or PCB contamination, especially critical in automotive harness environments.
Is there a direct NPN complement to PBRP123YT-QR?
Yes-the NPN counterpart is PBRN123YT-Q, which shares identical R1/R2 values (2.2 kΩ / 10 kΩ), SOT23 package, AEC-Q101 qualification, and −600 mA rating. It supports complementary low-side switching topologies and is pin-compatible for layout reuse in dual-drive circuits.
